Patent KR-900007374-B1 (KR)
Title: Bit clock signal generating apparatus of digital demodulating apparatus
Inventor: HAYAMA ATSIC
IPC: H04L7/027
Filed: 1987-09-29
Granted: 1990-10-08
Abstract: The pulse generator includes an input terminal for an ETMsignal, a phase-lock loop comprising a comparison circuit, a lowpass filter end voltage controlled oscillator. Also included is a circuit for playback drive, a change-over switch and generator circuits for the detection-window pulse used as a comparison wave for the PLL. The generator circuit for the detection-window pulse are designed so that the window pulse can be generated with different pulse-widths, depending on the changes in the bit rate of the digital signal to be demodulated, e.g. to give a window pulse having a pulse-width suitable for magnetic recording-replay systems equipped with rotary heads. Each of the generator circuits is based on an XOR-gate and a delay circuit.

Granted: 1994-06-16
Abstract: An over the needle catheter with adapter (10) that has an integral valve (11) in a passage (14). Distal (12) and proximal (13) parts form the adapter (10) along an axis "A". The distal part (12) communicates with a catheter (15). A hub (17) conjugates with the proximal part (13) and has a needle (18) extending along the axis "A" and through the passage (14) when the hub (17) is within the proximal part (13). A valve assembly (19) has an elongate resilient member (20) captured in the passage (14) between the parts (12,13). A proximal portion of the valve assembly (19) is engaged by a fitting (22) to open the valve. A valve seat (23) in the passage has a frusto-conical surface (24) located coaxial about the axis "A" and facing the distal part (12). The seat (23) engages a chamfered surface (25) on the elongate resilient member (20) to seal and prevent flow and to allow flow when the seal is broken by axial compression of the elongate resilient member (20) by the fitting (22). A septum like end (28) across the elongate resilient member (20) permits the needle (18) to pass therethrough in a resealable fashion. The elongate resilient member (20) has a diametrically reduced cylindrical body (32) extending to the septum like end (28). The passage (14) has an annular space (33) about the reduced cylindrical body (32) and terminates in a distal area (34). The distal area (34) has flow channels (37) which extend between the annular space (33) and the distal part (12). A method has steps of locating the parts along an axis "A" and capturing the elongate resilient member (20) by engaging the axially aligned parts (12,13) to force the elongate resilient member (20) against a valve seat (24) for sealing the passage (14) and preventing flow. Placing a needle (18) carried on a hub (17) along the axis "A" and through a septum like end (28) of the elongate resilient member (20) allows the needle (18) to be withdrawn from the septum like end (28) and to reseal the passage (14). Applying fastening means to secure the parts is a step.   <IMAGE>   <IMAGE>

Abstract: A method and apparatus for achieving reliable transmission of signalling messages in a cellular system in which the frequency plan, frequency/time slot allocation plan, code channel allocation plan, or dynamic/adaptive channel allocation rule of the system is violated by allowing adjacent base stations to reuse particular frequencies/time slots/channels for signalling a particular mobile station. In situations where signalling messages, such as handoff commands, which are communicated between a base station and a mobile station are not properly received by the mobile station, an alternate communications channel will be established to ensure the reception of these messages. The alternate channel is provided by repeating the message through a channel associated with a base station which has better radio characteristics. The channel selected for transmission of the message by the new base station will be on the same frequency/time slot/code as used by the established connection. <IMAGE>

Abstract: The invention relates to a circuit arrangement suitable for operating a low-pressure mercury discharge lamp by means of a high-frequency current, comprising   circuitry (I) for generating the high-frequency current from a supply voltage, and a modulator (II) for the substantially square-wave modulation of the amplitude of the high-frequency current with a modulation frequency f.   According to the invention, the circuit arrangement is further provided with circuitry (V) for limiting an amplitude of a re-ignition voltage across the low-pressure mercury discharge lamp to a voltage Vi. It is achieved by this that the interference with infrared systems caused by a lamp operated on the circuit arrangement is substantially fully suppressed. <IMAGE>

Abstract: 본 발명은 비디오 라이트장치에 관한것이다. 그의 주요구성은 다음과 같이 이루어진다. 리드스위치는 비디오 카메라와 밧데리팩 회로부사이에 설치된다. 비디오 카메라기 작동할때의 전류흐름은 리드스위치에 의해 감지된다. 비디오 라이트는 감지된 전류값에 따라 온, 또는 오프된다. 전원이 특정전압에 미치지 못할 경우에는 비디오 라이트는 꺼진다. 
     다른 실시예로는, 촬영시의 광량이 포토 트랜지스터에 의해 전류로 변환된다. 전류가 임계레벨보다 적을때, 비디오 라이트는 켜진다. 
     임계레벨은 가변 레지스터에 의해 변화된다.
