Abstract

A feature pack coupled to and interfaced with a cellular phone, which is able to relieve the cellular telephone from performing tasks associated with several of battery power draining features of the cell phone thus preserving the power of the battery of the cellular telephone. The feature pack, while interfaced and coupled to the cellular telephone, uses its own circuitry and battery to perform these tasks. The feature has a compartment within which the cellular telephone (or other device with which it is coupled) is disposed. The feature pack has circuitry separate from the coupled device, but is able to use audio and other types of signals from the coupled device to perform such tasks as using speakers, microphones, recording voice and audio signals and communicating with external devices via a Blue Tooth interface.

Description

FIELD OF THE INVENTION

The present invention generally relates to the field of electronic devices. In particular, the present invention provides a feature pack coupled to a portable device to enhance many of the features of the device during operation.

BACKGROUND OF THE INVENTION

In the past decade, manufacturers of portable communication devices (e.g., smart cellular phones, tablets, laptops, notebooks) have been designing and manufacturing these devices with increasing amounts of new features. While many of the relatively new features are quite useful, the main and most important features are the standard features that existed in the earliest version of such devices and are still resident in virtually all of these devices. These features are a device's ability to provide relatively high quality of voice signal processing, the ability to play music and the ability to record voice and audio signals. In particular, the audio output power and the quality of the audio output signals when playing music, or when conversing in a telephone conversation or recording a conversation during a meeting are key features.
It is well known by many users of such portable communication devices that the constant use of such main features necessarily results in the drainage of battery power. A portable device operating under reduced battery power inevitably leads to a reduction in the quality of voice, audio related features and other features whose usage tend to significantly drain the battery power of such devices. Also, the range of the volume of the output speakers are necessarily lowered, which makes it difficult to use the device as a speaker phone especially for users who are hearing impaired. Even though the batteries can be recharged to full level (assuming the user has his/her battery charger available), in many cases users are caught with low battery power during inopportune moments such as during important phone calls. Further, after discovering a relatively low battery level, users will often opt to refrain from listening to music and/or opt to switching off the device to save battery power. Neither one of these two options is desirable as each severely limits the usefulness of such devices and are in conflict with the main reasons for which they were designed.
It is therefore a desire of users of such devices to use the features provided by such devices without having to drain the battery power thus avoiding lowered quality of operation of such devices.

SUMMARY OF THE INVENTION

The present invention provides a feature pack device which when coupled to and interfaced with a portable device is able to perform a plurality of tasks typically performed by the portable device thus helping to preserve the energy level of the battery of the portable device. The feature pack comprises circuitry controlled by a microprocessor that can be interfaced with a user via user accessible actuators where such circuitry and associated components are able to process the signals from the portable device to perform the plurality of tasks. The feature pack of the present invention uses a power source for its circuits, components, and user accessible actuators that are separate and distinct from any power source used by the portable device.
In one embodiment, the feature pack of the present invention comprises a compartment within which a cellular telephone can be snugly disposed allowing said telephone to couple to and interface with the feature pack. The cellular phone provides a plurality of signals to the feature pack, which processes said signals using a plurality of circuitry, electrical and electronic components and user accessible actuators all of which are separate from the cellular telephone.

DETAILED DESCRIPTION

The present invention provides a feature pack device, which when coupled to and interfaced with a portable device is able to perform a plurality of tasks or many of the features typically performed by the portable device thus helping to reduce the burden on the battery of the portable device and, therefore, helps to preserve the energy level of the battery of the portable device. The feature pack device comprises user accessible actuators coupled to a plurality of circuits to facilitate processing of received portable device signals and to perform tasks heretofore performed by the portable device. The circuitry of the feature pack is controlled by a microprocessor that can be interfaced with a user via the user accessible actuators where such circuitry and associated components are able to process signals from the portable device to perform the tasks and/or provide the features previously done by the portable device, but which are now done by the feature pack. The performance of tasks and/or provision of features by the feature pack using its own power source separate and distinct from any power source of the portable device where such tasks and features were heretofore done by the portable device significantly relieves the power burden on the portable device. The portable device may be electrically, electronically and mechanically coupled to and interface with the feature pack which performs many of the features using its own power source (e.g., a rechargeable battery), that it uses to power its own circuits and components to process voice, audio, and other types of signals that would normally be processed by the portable device. The feature pack may be coupled and interfaced with the portable device so that both devices may be physically combined into a unit where the feature pack is able to receive signals from the portable device.
In one embodiment, the feature pack of the present invention comprises a compartment within which a portable device such as a cellular telephone can be snugly disposed allowing said telephone to couple to and interface with the feature pack. The cellular phone provides a plurality of signals to the feature pack, which processes said signals using a plurality of circuitry, electrical and electronic components and user accessible actuators all of which are separate from the cellular telephone and all of which are powered by the battery of the feature pack. Thus, the feature pack, using its own battery, takes on the burden of many of the processing tasks that would normally be performed by the portable device thus reducing the burden on the battery of the portable device.
One embodiment of the feature pack of the present invention is shown in FIGS. 1-4. In particular, FIGS. 1-4 depict a feature pack that is designed to couple and/or interface with a portable electronic device and perform many of the features of the electronic device. In the embodiment shown in FIGS. 1-4, the feature pack shown is designed to interface and/or couple with a portable smart cellular telephone having a particular physical configuration. It will be understood, however, that the feature pack of the present invention can be designed for different types of devices including portable electronic devices and other electronic devices; that is, the feature pack is not limited to be used only with a smart cellular telephones as discussed with respect to FIGS. 1-4. The embodiment shown in FIGS. 1-4 is used for illustrative and ease of explanation purposes and does not, in any manner, limit the usage of the feature pack to portable cellular telephones. Devices such as laptops, notebooks, tablets can also be used with the feature pack of the present invention.
Referring to FIG. 1, there is shown a front view of an embodiment of the feature pack 100 of the present invention designed for a cellular telephone. The feature pack 100 has a compartment 104 in which a cellular telephone (not shown) can be disposed. Feature pack 100 is designed so that a cellular telephone disposed in compartment 104 fits snugly within said compartment. Further, the cellular telephone is assumed to have a female RCA jack positioned so that when the phone is placed in compartment 104, male RCA jack 300 is in alignment with the corresponding female jack of the cellular phone and a connection is made. Similarly, male connector 330 of the feature pack aligns with a corresponding female connector (not shown) of the cellular phone. Male connector 330 is connected to external charger cord 416 whose end has an AC (Alternating Current) plug and charging circuit that provides DC (Direct Current) power to the feature pack 100 and to the cellular telephone disposed within compartment 104. Feature pack 100 further has microphone 302 and telephone speaker 350. Also, feature pack 100 has a relatively small chamber within the rear surface of compartment 104 where a memory card 338 can be disposed. A metal strip 102 is fused into the material (e.g., rubber, silicone) used to construct the body of feature pack and can possibly be used for an additional antenna component for the feature pack. The material can be layered and voids (not shown) can be formed between the layers of the material wherein electronic circuits along with their components may reside. The feature pack may also have a relatively large void for storing its battery. Other components of the feature pack of the present invention are shown in FIG. 2.
Referring now to FIG. 2, there is shown a rear view of the feature pack 100 of FIG. 1. In particular feature pack 100 has openings 102 and 116, which may be used as access locations to control buttons and other user interface actuators of the cellular phone when snugly fit within compartment 104 of the feature pack of the present invention. Openings 112 and 118 are other examples of the feature pack 100 of the present invention providing access to user actuators (e.g., buttons, sliding switches) of the cellular telephone when disposed in compartment 104 of the feature pack of the present invention. A control button or a user accessible actuator of the feature pack 100 is an electrical or electro-mechanical component of the feature pack of the present invention designed to be used, manipulated, operated or otherwise physically activated by a user of the feature pack to input signals, set conditions or otherwise alert the feature pack of occurrences of a physical condition initiated by the user. A metal strip 108 embedded in the material of the feature is available for use as an antenna for the feature pack or an antenna that can be coupled to an antenna of the portable device disposed in compartment 104. As will be discussed herein, the feature pack 100 has several user accessible actuators located on its rear surface whereby such actuators are directly electrically connected, coupled or otherwise interfaced to circuitry located within the layers of material of the feature pack body 100.
Sliding control actuator (or volume control actuator) 130 has a sliding button, which can be slid right or left by a user to control the volume of speakers 348 and 346, which may be stereo speakers. Volume control actuator 130 can be used to control the volume of speaker 350 (see FIG. 1) located at the front of the feature pack. Thus, depending on the speaker being used, volume control actuator 130 can directly control the volume of the selected speaker based on the manipulation of actuator 130 by a user. Actuator 132 may be a two-position actuator that allows a user to select which set of speakers he/she wants to use. In particular, the user may select to use speaker 350, say for a telephone call, or speakers 346 and 348 when listening to music originating from the telephone or from an external device in communication with the feature pack 100 via a blue tooth connection as will be described infra Audio recording actuator 114 is another type of sliding actuator; this actuator may be a three-position sliding actuator (Play-Off-On) whereby a user of the feature pack 100 can play recorded voice or audio signals stored in memory card 338 (see FIG. 1). Accordingly, a user can also record incoming voices, incoming audio signals, his/her own voice and any other audio signals that can be received by the feature pack or any other voice/sounds within the hearing vicinity of the feature pack user. The feature pack, of course, has a microphone 302 (see FIG. 1) that may be used for voice and/or sound recordings.
Continuing with the various actuators shown in FIG. 2, there is shown a two-position actuator 124 that can be used by a user of the feature pack to switch ON or OFF a Blue Tooth circuit of the feature pack. The feature pack of the present invention has a Blue Tooth circuit (which will be discussed infra; see FIG. 4, circuit 332) that can receive voice, audio and other types of signals from an external device paired with the feature pack 100 of the present invention. Also, the Blue Tooth circuit is able to transmit voice, audio and other types of signals to the external device. The term “Blue Tooth” is a well-known term that refers to a telecommunication standard developed to allow mobile or fixed devices to communicate with each other over relatively short distances using specifically defined electromagnetic signals.
Actuator 128 is a two-position switch and is used to switch ON or OFF a tone generator circuit (see FIG. 4, circuit 336), which is used by a user when recording a telephone call in order to comply with any law requiring that the user disclose to the party to whom he/she is talking that the call is being recorded and to periodically insert tones of certain frequencies into the conversation while the conversation is being recorded. The inserted tones are done with the tone generator circuit 336 (see FIG. 4 discussed infra). In addition to inserting tones into a conversation being recorded, the feature pack of the present invention allows users to record various rings of the cellular telephone so that it can recognize when a cellular phone in compartment 104 is receiving a call. A ring tone detect circuit is able to detect the ring tone resulting from an incoming telephone call.
Actuator 122 is used to store the ring tones as will be discussed infra Components 352 and 354 are not actuators but are indicators of the status of the memory card 338 and the amount of power left in the battery (326; see FIG. 4) of the feature pack respectively. When the memory card is full, light component 358 is activated indicating to the user that memory card 338 has reached its capacity. An outline 134 of the battery compartment for the feature pack is shown in dashed lines. Finally, two-position actuator 120 when set in an ON position causes a charge circuit 416 of connected to the feature pack to charge the battery of the feature pack and also the battery of the cellular phone coupled to the feature pack.
FIG. 3 shows the right side of FIG. 2 where a female RCA jack is positioned to receive a male counterpart from a headset-microphone device connected to the feature pack by a user. All of the aforementioned actuators engage directly the electrical and electronic circuits residing within voids formed by layers of material. A block diagram of such circuits is shown in FIG. 4.
Referring now to FIG. 4, the various circuits of the feature pack are shown. The feature pack is still being described in the context of a cellular telephone disposed within compartment 104. In order to fully describe the operation of the various circuits of the feature pack, at least three modes of operation of the feature pack will be discussed.
In a first mode of operation a device such as a cellular telephone is disposed in compartment 104 of the feature pack and thus such device is coupled to the feature pack via the male RCA jack 300 and a corresponding female RCA jack (not shown) of the cellular telephone. Also, in this mode of operation, the external headset/mic shown in FIG. 4 is not connected to the feature pack of the present invention. It should be noted that a portable device such as a cellular telephone may have another type of connector with which it connects to external devices such as the feature pack. In other cases, the feature pack of the present invention will be constructed and designed with a matching connector; that is the feature pack design is not limited to only one type of connector. The connection between the feature pack and the cellular telephone thus disconnects audio and microphone lines of the female RCA jack connector (not shown) from circuits within the cellular phone. The signals on the audio line and microphone line of the female connector (not shown) of the cellular telephone are thus available to the feature pack as those lines are now directly connected to RCA jack 300 and are no longer connected to the internal circuitry of the cellular telephone. In interface circuit 308, the microphone line 304 of the feature pack is connected to the microphone line of the RCA jack 300. Also, audio line 306 of the RCA jack 300, which is now connected to the audio line of the cellular telephone, is also connected to one end of switch S1 and to the input of Audio/Mic select circuit 324 as shown. Because the external headset and microphone shown in FIG. 4 are not connected to the feature pack, the detection circuit 314 does not detect any energy on microphone line 318 of the external headset/mic and sends an appropriate signal to microprocessor 360 via two-way control line 364. In response, microprocessor determines that no external headset/mic is connected to female RCA jack 310 and thus keeps switch S1 in the open position as shown.
Continuing with this first mode of operation, in the embodiment shown and considering the discussion above, there are three signals that can be received by the feature pack of the present invention. They are (i) signals from audio line 306 which are audio signals being received by RCA jack 300 from the cellular telephone disposed in compartment 104 of the feature pack; (ii) signals from microphone 304 of the feature pack; because the headset/microphone is not connected to the feature pack, there are no microphone signals on line 318 (no energy detected by detector 314) and thus microprocessor 360 sends a control signal via control line 402 to select microphone 302 to allow signals from microphone 302 to pass through Mic Select circuit 316 to path 320 and onto the input of Audio/Mic select circuit 324; and (iii) Blue Tooth signals received wirelessly by Blue Tooth circuit 332.
In particular, microphone signals from male RCA jack 300 and female RCA jack 310 are fed to Mic Select circuit 316. Because no energy is detected by Detection circuit 314 Microprocessor 360 receives a signal from circuit 314 indicating that the headset and microphone are not connected (no energy is detected on the microphone line 318; i.e., no signal from female RCA jack 310) and thus keeps switch S1 open and selects the microphone 302 of the feature pack; that is, signals from microphone 302 appear on microphone line 304 and are caused to be routed through microphone select circuit 316 onto path 320 to one of the inputs of Audio/Mic Select circuit 324. Signals on Audio line 306, which may be audio signals from the cellular phone disposed in compartment 104 of the feature pack, are present at the input to Audio/Mic select circuit 324 on path 306. Finally, signals received wirelessly by Blue Tooth circuit 332 appear on path 372 and are thus present at the input to Audio/Mic Select circuit 324
Therefore, the input to Audio/Mic Select circuit 324 may be (i) a signal from the external device coupled and interfaced with the feature pack, (ii) a wireless signal received by the Blue Tooth circuit 332 or (iii) a signal from the microphone 302 of the feature pack.
Depending on the setting selected by a user of the feature pack for actuator 136, one of the inputs to Audio/Mic select circuit 324 will be selected by microprocessor 306 with the use of a control signal sent by the microprocessor via control line 368. For example, if the user sets the Blue Tooth actuator 124 to its ON position, and the Select Input actuator 136 is set to BT (i.e., Blue Tooth) then the Blue Tooth signal on path 372 will be selected (recorded and stored if actuator 114 is set to ON) and played on either speakers 346, 348 or speaker 350 depending on the set of speakers selected by the user using actuator 132. If, however, actuator 124 is set to the MIC (microphone) position, the signal from microphone 302 is selected (recorded and stored if actuator 114 is set to ON) and played on either speakers 346, 348 or speaker 350 depending on the set of speakers selected by the user through the user of actuator 132. Finally, if actuator 136 is set to AUD (audio), then the signal on path 306 is passed through circuit 324 to path 382 (recorded and stored if actuator 114 is set to ON) and played on either speakers 346, 348 or speaker 350 depending on the set of speakers selected by the user through the use of actuator 132. The selection of the input is done by microprocessor 360, which transmits the proper control signal to Audio/Mic Select circuit 324 via control line 368.
It should be noted that in this first mode of operation, the broadcasting of Blue Tooth signals by Blue Tooth circuit 332 is received by any device having Blue Tooth capability and where said device is paired with the Blue Tooth circuit 332 of the feature pack. The feature pack will automatically pair with nearby Blue Tooth devices, which have been loaded with a code associated with the feature pack. In this first mode, signals received wirelessly are presented onto path 372, recorded, stored and played in real time through the front speaker 350 or the rear stereo speaker 346 and 348. Also, either audio signals on path 306 or microphone signals (from headset microphone or microphone 302) on path 320 are transmitted to nearby external Blue Tooth-enabled devices. The feature pack can be designed so that audio signals from path 306 are transmitted to nearby Blue Tooth devices and that the microphone signals are not transmitted by the Blue Tooth circuit 332; this can be a default setting, which can be changes based on user preference.
In the case of interruptions where the feature pack is operating in the first mode and an interrupting signal of relatively high priority is received, the feature pack may be programmed to a default setting for such occurrences. For example, when the device disposed in compartment 104 of the feature pack is a cellular phone or any other device with communication capabilities and an incoming call has been detected, a ring detect circuit 322 will detect the ring and temporarily postpone whatever task, if any, was being performed by the feature pack and answer the call. The feature pack is able to detect a ring because the ring signal will be present on audio line 306, which is directly connected to ring detect circuit 322. The various ring signals of the device disposed in compartment 104 can be stored in ring detect circuit 322 as follows.
Select ring signal button 122 is depressed twice in quick succession signaling to the feature pack that the user desires to store one or more rings in ring detect circuit 322. The user can then operate the device in compartment 104 to generate different rings and after each ring, the user depresses the ring select button 122. This procedure can be repeated as many times as the number of rings that the user desires to store. The user can then again depress button 122 twice in quick succession to signal end of storing of rings. When any of the stored rings are detected, the feature pack selects path 306 using the proper control signal on control line 368 to allow the user to participate in the telephone call. The user can record the phone call by activating 114 to the ON position and setting actuator 128 to the ON position so that audio tones are injected into the conversation notifying the calling party that the call is being recorded. The user of the feature pack preferably also advises the calling party that the call is being recorded in addition to switching ON the Tone Generator 336.
In the second mode of operation, the headset shown is connected to the feature pack. Still referring to FIG. 4, when the headset is connected (via female RCA jack connector 310; see FIGS. 3 and 4), whether an external device is positioned within compartment 104 of the feature pack is irrelevant. This is because, once microprocessor 360 receives a signal from Detector circuit 314 indicating that a second microphone has been detected and thus an external Headset/Microphone has been connected to the feature pack, the feature pack gives priority to the external headset. In particular, microprocessor 360 causes switch 51 of input circuit 308 to close (by transmitting the proper control signal onto control signal line 362) thus connecting audio line to 306 to the external headset. Further, the microphone of the headset is selected by microprocessor 360 at Mic Select circuit 316. The user still has the capability to record either his voice from the use of the headset microphone or any signal on path 306. Either one of these signals can be selected by the user through activation of actuator 136 to the proper position. As with the first mode, the user activates actuator 114 to the ON position to do a recording. Also, as with the first mode, an incoming call will be handled by the feature pack Ring Detect circuit 322 detecting a ring signal and then allowing the user to answer the call using the external headset/microphone. Microprocessor 360 selects path 306 in case the user wants to record the call. Again, as with the first mode, the user preferably switches ON the Tone Generator 336 and notifies the calling party that the telephone call is being recorded. The recorded call is stored in detachable memory card 338 as previously described. Upon termination of the telephone call, the feature pack returns to the task, if any, that it was performing immediately prior to the telephone call.
In a third mode of operation, there is no external device connected to the feature pack. In this mode, the feature pack can be receiving signals via the Blue Tooth circuit 332 and may also be used to record a user's voice when the external headset/microphone is connected to the feature pack. When the headset/microphone is not connected to the feature pack, the microphone 302 of the feature pack can be used to record voice signals and other sounds detected by microphone 302.
Referring temporarily to FIG. 2, when actuator 124 is set to ON and actuator 132 is set to BT (for Blue Tooth), and the feature pack is paired with a nearby device, the signals received via Blue Tooth circuit of FIG. 4 are on path 372, which is one of the inputs to Audio/Mic select circuit 324. Continuing with FIG. 4, when no headset/mic is connected to the feature pack and actuator 136 is set to BT (for Blue Tooth) the Blue Tooth signals are selected by Audio/Mic select circuit 324 and such signals appear on path 382 where they may be recorded when actuator 114 is set to ON. The recorded Blue Tooth signals may then be stored within memory card 338. Also, the Blue Tooth signals on path 382 may be amplified by amplifier 330 and applied to either stereo speakers 346 and 348 or speaker 350 depending on which set of speakers is selected through the use of actuator 132. Continuing with FIG. 4, if the headset microphone is connected to the feature pack, then Detection circuit 314 will detect energy from the microphone of the headset and send that information to microprocessor 360. The microprocessor 360 will activate Mic Select circuit 316 to pass signals from the headset microphone onto path 320, which is another input to Audio/Mic select circuit 324. If the actuator 114 is set to ON and actuator 136 is set to MIC, then the signals from the headset microphone are selected (by microprocessor 360 sending the proper control signal onto control line 368), and thus appear on path 382 to the input of Audio recording circuit 334 where they are recorded and stored in memory 338 via path 336. A user can thus use the feature pack as a personal recording device by its user.
Still continuing with FIG. 4, when the headset/microphone device is not connected to the feature pack via RCA female jack 310, the microprocessor 360 selects feature pack microphone 302 (through a control signal on control line 402) and all signals (i.e., voice and/or sounds) captured by microphone 302 are transferred onto path 320 and appear at one of the inputs to Audio/Mic Select circuit 324. When actuator 136 is set to MIC, the signals from microphone 302 are selected and pass onto path 382. If actuator 114 is set to ON, then the sounds and/or voices from microphone 302 are recorded and stored in memory card 338. It is thus that the feature pack of the present invention can be used to record sounds, voices and other types of audio signals. For example, a user at a conference or attending a meeting may use the feature pack of the present invention to record such events.
Referring now to FIGS. 5-7, another embodiment of the feature pack of the present invention is shown. This embodiment operates in much the same fashion as the embodiment of FIGS. 1-4 including the operation of the circuitry disclosed in FIG. 4. FIG. 5 shows a front view of a feature pack having a speaker 212, a microphone 218, a compartment 230, within which a portable device (such as a cellular telephone) can be snugly disposed. The portable device can connect to the feature pack via male RCA jack 214 or some other connector appropriate for the portable device. The feature pack of FIG. 5 also contains connector 216 that interfaces with charger 220 comprising a connector at one end and an AC plug at the other end. The feature pack of FIG. 5 further has an extended portion part of which is a rest area 208 for a user's finger. The rest area is directly above an opening 206 through which a user can pass through a chain like object or a string like object to carry the device around his/her neck. Speaker 212, is positioned so as to be useful to users who are hearing impaired. A mechanical switch 200, which when depressed by a user causes light 204 (may be an LED) to illuminate thus serving as a small flashlight to assist users in poorly lit situations, where for example, a user has difficulty inserting his/her key into a keyhole. The mechanical switch 200 can be accessed through opening 202. Opening 236 may be used depending on the architecture of the portable device residing in compartment 230. For example, opening 236 shown in FIG. 6 may be an opening for a camera lens available in many portable devices such as cellular telephones.
FIG. 6 is a rear view of FIG. 5 showing openings 206, 236 and 202 already discussed above. Further, FIG. 6 show an actuator 238 that can be set by a user of the feature pack to select which speakers he/she wants to use. Stereo speakers 234 and 235 are shown positioned at the bottom of FIG. 6. Speaker 212 can be seen in FIG. 5 where it is shown positioned at the top of the feature pack. Actuator 210 (also shown in FIG. 5) is a sliding volume control actuator used to control the volume level of the speakers. Another view of the volume control is shown in FIG. 7, which shows a left side view of FIG. 5. FIG. 7 also shows opening 228 (also depicted by FIGS. 5 and 6) which is used to store a magnifying glass. The compartment 224 shows the outline of the space 224 and a pull out opening 222 providing access to the compartment in which the magnifying glass is stored.
While various aspects of the present invention have been described above, it should be understood that they have been presented by way of example and not limitation. It will be apparent to persons skilled in the relevant art(s) that various changes in form and detail can be made therein without departing from the spirit and scope of the present invention. Thus, the present invention should not be limited by any of the above described exemplary aspects, but should be defined only in accordance with the following claims and their equivalents.
In addition, it should be understood that the figures in the attachments, which highlight the structure, methodology, functionality and advantages of the present invention, are presented for example purposes only. The present invention is sufficiently flexible and configurable, such that it may be implemented in ways other than that shown in the accompanying figures.
