Title: Device for deriving a synchronizing signal
Inventor: PETERS JOSEPH H
IPC: H04L7/08
Filed: 1986-09-23
Granted: 1994-12-19
Abstract: The device for deriving a synchronizing signal comprises a synchronizing signal detector (1), an output (3) of which is coupled both directly and via a delay unit (18) to inputs (4 and 19, respectively) of a signal combination unit (5). The output (6) thereof is coupled to an input (7) of a flywheel counter (8). One output (9) of the flywheel counter (8) supplies the synchronizing signal. Another output (9) is coupled to an input (11) of the signal combination unit (5). The first input (4) and the second input (11) of the combination unit (5) are coupled to inputs of a time slot circuit (12). The first input (4) and the third input (19) of the combination unit (5) are coupled to inputs (20, 21) of a further combination unit (14). The output of the time slot circuit (12) is also coupled to an input (13) of the combination unit (14).The delay time (T) of the delay unit (18) is equal to n times the period of the synchronizing signal. Therefore the device is less sensitive to "false lock" and can capture the synchronization rapidly again after a loss of synchronization.

Title: Owner identification system for electronic equipment, particularly automotive audio equipment
Inventor: HARARUTO BOCHMAN
IPC: G08B13/04
Filed: 1987-02-26
Granted: 1998-12-01
Abstract: To provide recognition of personal data, for example the registration number of a vehicle in which a car radio is installed, the car radio includes a non-volatile memory (4) which can be selectively connected to a data input arrangement (2) for the electronic equipment (1) to store the registration number therein. A recall switch (S2) is provided to selectively connect the non-volatile memory (4) to the display (3) for displaying the personal recognition data or, in normal operation, to connect the display to the output of the electronic equipment, to display data pertinent to the operation of the electronic equipment, for example the frequency of a tuned station. Two additional memories (5, 6) store, respectively, a predetermined code word and, upon entry from the data entry arrangement, the same code word. Unless the two code words agree, the recall switch (2) is changed to display only the personal recognition data, for example the vehicle registration. Thus, the vehicle from which a radio has been stolen will be indicated unless the correct code is entered into the additional, and comparison memory. Few electronic components are needed which form part of the electronics of the car radio so that attempts to override the memory or destroy it will result in overall destruction of the electronic equipment.

Granted: 1990-05-10
Abstract: The p-channel MOS transistor is connected in series to a floating gate n-channel MOS transistor forming a memory cell, so that the p- channel MOS transistor functions as the load of the memory cell. The operational characteristic of the p-channel MOS transistor determines the data-writing current of the memory cell. Hence, hardly any change occurs in the data-writing current, even if the operation characteristic of the memory cell changes. A semiconductor memory includes memory cells constituted by floating gate n-channel MOS transistors. The memory further includes a data-reading, column- selecting circuit comprising p-channel MOS transistors.

Abstract: VTR(Video Tape Recorder)에 있어서 헤드 스위칭 제어회로에 관한 것으로 특히, 고밀도 기록을 위해 드럼속도를 높혔을 시 헤드 스위칭 제어회로에 관한 것이다. 드럼모타로부터 FG의 신호를 입력하고 PG의 신호를 리세트단에 입력하여 헤드 스위칭 펄스의 타이밍을 출력하는 카운터와, 카운터의 출력신호 및 수평동기신호를 입력하여 헤드 스위칭 펄스시간을 검출하는 검출수단과, 검출수단의 출력신호 및 임의의 주파수를 가진 클럭신호를 입력하여 헤드 스위칭 제어신호를 발생하는 제어수단으로 구성된다. 따라서, 고밀도 기록시 테이프상의 2트랙 또는 3트랙을 1필드로 할 경우 1필드 기간내에 발생하는 헤드 스위칭 제어신호를 수평귀선소거기간에 발생하여 수직귀선소거기간이 아닌 기간에서 헤드 스위칭이 발생될 때 생기는 스위칭노이즈를 없앨수 있는 이점이 있다.

Abstract: 채널 가산/삭제방법은 가산/삭제기능을 갖는 방송수신장치에 있어서 해당 채널을 선국하지 않고도 가산/삭제모드를 설정하기 위한 것이다. 이를 위하여 키입력수단을 통해 가산 또는 삭제모드를 설정하기 위한 제어신호가 인가되는 지를 체크하기 위한 키체크과정; 가산 또는 삭제하기를 원하는 방송채널정보가 인가되는 지를 체크하고, 방송채널정보가 인가되면 소정 메모리에 저장 또는 삭제하기 위한 가산 또는 삭제처리과정; 키체크과정에서 가산 또는 삭제모드를 제어하는 신호가 인가될 때 이미 시스템자체에 모드가 설정되어 있는 경우에는 가산 또는 삭제모드를 해제하는 과정을 포함하도록 구성된다. 따라서 가산 또는 삭제모드설정이 용이하다.
