Description of the application for registration of a utility model

Haar, 24 April 1992 Haar, 22 June 1992 Page 1/2,

State of the art:

Screen display devices such as television/video/satellite receivers which are equipped with cathode ray tubes generate electromagnetic radiation and an electrostatic charge due to the electron acceleration and deflection voltages required and the subsequent electron deceleration when the electrons hit the image-generating surface of the cathode ray tube, (generally referred to as a 'screen' or 'color screen').

Problem:

The invention specified in the protection claim is based on the problem

that when approaching a switched on screen display device with

Braun tube of the observer depending on his distance

to the screen surface is exposed to electromagnetic radiation.

Due to the simultaneous electrostatic charging of the Screen surface additionally charges dust particles from this

attracted but also repelled.

(different charges attract / similar charges repel)

In order to prevent any possible damage to the viewer’s health, especially to his eyes, a minimum viewing distance from the screen surface is recommended.

(e.g.: unsupervised children in front of the television with the habit of repeatedly walking or sitting too close to the television.)

Solution:

This problem is solved with the features listed in the protection claim

solved. This is the following device:

'Infrared controlled coaxial switch for connection to TV/video/

Satellite reception and playback devices, for the purpose of interrupting

or interference with the reception signal when approaching possible

To prevent eye damage caused by too short a viewing distance'. The device constantly measures using an infrared sensor

the distance and evaluates the result.

If an adjustable minimum distance is exceeded,

the device blocks or interferes with the reception signal, this means that

Image and sound reception may be switched off or disrupted. The device itself is installed on, next to or under the Screen display device (e.g. television) positioned. Bank accounts

Benefits achieved:

The invention ensures that when the viewer approaches a screen display device within an adjustable minimum distance, the reception signal for the screen display is automatically interrupted or disrupted.

Looking at the interrupted or disturbed signal on the screen is pointless (white noise or a shadowy image). The viewer will only remain within the minimum distance for a very short time and will therefore only be exposed to a possible health risk caused by the viewing distance being too short for a short time.

When the viewer moves away from the screen display device, e.g. television, to the minimum distance, the reception signal is switched on again and interference-free reception is possible.
