Title: High power factor AC/DC convertor
Inventor: TERAMOTO SUSUMU
IPC: H02M3/335
Filed: 1992-10-01
Abstract: A converter comprises a rectifying circuit (RC1) which rectifies AC power supply (Ei), a switching transistor Q, which turns on and off so that the rectified voltage is applied across the primary winding (n1) of the transformer (Tr1) to provide a high frequency voltage across the secondary winding (n2). The secondary winding voltage is rectified by circuit (D1, D3, L2, C2) connected across the secondary winding. A choke coil (L1) and a diode (D1) are interposed between the rectifying circuit (RC1) and a smoothing capacitor (C1), and a capacitor (C3) is interposed between a first junction and a second junction. The first junction connects the choke coil (L1) to the diode (D1) and the second junction connects the switching device (Q1) to the primary winding (n1) of the transformer (Tr1). A control circuit U, coupled to a detection and comparison circuit (DET1) drives the switching transistor Q1 on and off at a high frequency (100 kilohertz) relative to the supply frequency and the inductance of the choke provides effectively a constant current at the high frequency. A power factor of up to 0,98 is achieved. In further embodiments (Figures 6, 11) the power factor may be 0.996. <IMAGE>
Patent GB-2260468-A (GB)
Title: Portable radio telephone
Inventor: YAMADA JUN
IPC: H04W88/06
Filed: 1992-10-07
Abstract: This equipment monitors the control channel number of a cellular mobile telephone system, (CMTS), through a radio transmission section (24) and a control section (26) for common use to CMTS and a microcellular system, (MCS), and answers a call from a base station or performs transmission. On the other hand, this equipment selectively receives the control channel number of MCS and answers a call from a base station or performs transmission. Either one of these actions is automatically selected on the basis of the reception level and system ID of the control channel number. At this time, standby-state reception is performed on the judgement as to which one of CMTS and MCS is to be accessed, by automatically detecting the positional condition of the equipment in use. When the equipment is moved to a different area in CMTS or MCS, either one of CMTS and MCS is automatically accessed after position registration. <IMAGE>
Patent GB-2261567-A (GB)
Title: Method and device for image coding of a video signal
Inventor: BRUSEWITZ HARALD
IPC: H04N7/50
Filed: 1992-10-13
Abstract: The video signal is converted to a bit stream by coding and quantising. The bit stream is stored in a buffer store before it is sent at a constant bit rate to a transmission line. Overflow in the buffer store and the buffer store being emptied prematurely have been problems giving rise to a deterioration in image quality. At the same time, the buffer store content should be as small as possible. According to the invention, the content in the buffer store is regulated by varying the step height in the quantiser. With the frame rate at the input being known and the frame rate and bit rate at the output being known, the ideal buffer store content can be determined. The actual buffer store content is sensed and compared with the ideal buffer store content and the difference between these two values is determined. The step height in the quantiser is adjusted as a function of the difference. The device according to the invention is preferably constructed as an integrated circuit, for example, a VLSI circuit. The method of coding may comprise hybrid transform/predictive coding. <IMAGE>

Title: Fish bite indicator
Inventor: HOFGARTNER JOHN LAWRENCE STIRL
IPC: A01K97/12
Filed: 1994-02-19
Abstract: A ball flasher bite indicator has a flashing or constant light (1) which is attached on one side to the line clip (3) and on the other side to a swinging arm (2). The fishing line runs through the line clip (3) thus rotating the swinging arm (2). When the arm rotates, it operates the switch (4) which completes the circuit therefore operating the light and the sound box (5). It should be noted that the sound box (5) is optional. The purpose of the flashing or constant light, during darkness, is to draw the attention of the fisherman to the fact that a fish has taken the bait. Consequently the fish is pulling the line of the particular rod on which the light is flashing or remains constant. The ball flasher bite indicator is supported by attaching it to a bank stick, via the clip (6). The bank stick would already be in use by the fisherman. <IMAGE>
