Parameter, which is configured, can be or including one or more turn around parameters.The example of turn around parameters includes：Steering angle, it is all Such as mechanical tilting device is configured or the angle of one or more elements of energy converter can be configured；Diffusion angle such as exists Occur in ultrasonic beam (for example, being expressed as the beam width of angle) such as the angles of threshold power；Focal length, such as ultrasonic beam gather Burnt degree it is maximum by centimetre as unit of distance etc.；Sender location, such as receiver relative to transmitter angle and away from From, transmitter relative to a distance from the receiver or absolute position of transmitter or receiver (for example, relative to given datum mark) It puts；And the relative orientation of transmitters and receivers, such as represented with parallel degree, transmitter energy converter and receiver change Difference of relative orientation of energy device etc..For example, in the case where an energy converter is parallel to another energy converter, it is believed that the two There are 0 degree of offsets for energy converter.In an energy converter in the case where being oriented perpendicularly to another energy converter, the two energy converters can To have 90 degree of offsets etc..

Another mechanism is to change the first turn around parameters, to adjust and/or improve the transmission of the ultrasonic energy to receiver Efficiency.Even if in the case of via the input received by communication device without new (second) value of specified turn around parameters, Can also turn around parameters be changed based on the input.For example, can at transmitter communication device from receiver come receive including The input of amount (for example, 120dB) for emitting ultrasonic energy just received.In response, transmitter can be by turn around parameters The value of (for example, relative orientation) changes into second value (for example, changing into 0 degree of offset from 90 degree of offsets) from the first value.As changing Change/adjustment turn around parameters as a result, can be improved to the efficiency of transmission of the ultrasonic energy of receiver, and what is just received is sent out Penetrating the amount of ultrasonic energy can increase (for example, increasing from 120dB as 140dB).For example, quantity of power at receiver can be by Receiver is monitored, and as generating the benchmark for the input that be sent to transmitter, is configured in parameter with adjusting it One or more configuration parameters.It in this way can be for example by changing inclining for the mechanical steering gear used in transmitter energy converter Tiltedly, by changing the power level of emitted ultrasonic energy, being turned by changing the electronics of the ultrasonic energy at transmitter To with beam shaping etc., to change the mode of sender to receiver transmitting ultrasonic energy.In this way, receiver can will in real time or The feedback of near real-time is provided to transmitter so that transmitter can send the sender to receiver mode of ultrasonic energy It is tuned, to improve the duration of the rate of transmission energy (for example, power), the continuity of energy transmission, energy transmission Deng.
