Title: Television receiver and remote control unit system esp. for video text reproduction separate from screen
Inventor: SEEGERT BERNHARD DIPL ING
IPC: H04N5/44
Filed: 1995-05-30
Abstract: The system includes a television receiver (FS) and a remote control unit (FB). The receiver (FS) has an arrangement for receiving and providing time selective analysis of a video text signal (VT) transmitted in the vertical sampling gaps. The digital video signal is time selectively separated from the television signal. The video signal (VT) is transmitted without demodulation and remodulation via a wireless transmission path (22), from the TV receiver (FS) to the remote control device (FB), where it is represented on an image play-back unit (26). The play back unit (26) is preferably an LCD image screen (26). The transmission path (22) is preferably a high frequency or infrared path. The play back unit (26) may be used for selectively reproducing other information e.g. electric timing, alarms or small images for an image, in image play-back.

Title: Inflatable airbag for vehicle
Inventor: NAKAYAMA KAZUHIRO
IPC: B60R21/2342
Filed: 1995-11-07
Abstract: The airbag comprises inflater side material and an occupant side material of the same size. The two pieces of material are sewn together at the edges. The inflater side material has a central through opening for attachment of the inflater. The two pieces of material can be attached by tearable stitches which are torn by unfolding pressure. The tearable stitches are arranged in sections in the circumferential direction at spaces about the opening. Some of these stitches are weaker than others so that, by unfolding, the weaker ones tear before the stronger ones. Thus the airbag unfolds from the outside in.

Patent DE-19617630-A1 (DE)
Inventor: KAPANEN PEKKA
IPC: G10L25/78
Filed: 1996-05-02
Abstract: The invention relates to a method for mutual synchronization of the transmitter's speech encoder and the receiver's speech decoder in a communication system utilizing discontinuous transmitter between the transmitter and the receiver. The discontinuous transmission comprises temporally sequential frame periods of which some periods will contain transmitted frames and some periods contain no transmission; whereby the method contains steps to generate information transmission periods (200) comprising at least one frame and containing information given by a user to said transmitter device, and silence periods (208, 209) having a length of at least one frame period and containing other information than that given by the user. The discontinuous transmission further comprises an irregularly occurring period (T) comprising at least one frame between the information transmission period (200) and the next silence period (208, 209), the irregular period forming a hangover period to determine the information relating to the silence period. In the method according to the invention the number of frame periods is counted in the receiver until a certain moment; the beginning of said silence period (208, 209) is detected; and based on said counted number of frame periods and the beginning of the silence period (208, 209) it is decided whether or not there is a hangover period (T) of said type between said information transmission period (200) and the silence period (208) following the information transmission period.
