Patent GB-2254758-A (GB)
Title: Bias stabilizing ciucuit.
Inventor: JANG JONG-JIN
IPC: H04L25/06
Filed: 1991-12-02
Abstract: There is disclosed a circuit for stabilizing the bias of a paging receiver. An oscillation control signal of a first period is generated (104) at a time when a voltage source 106 is connected to RF components 101, 102, 103. An oscillation means 107, 108 generates a center frequency signal of a received modulated signal in response to the oscillation control signal. A demodulation means 102 demodulates the center frequency signal so as to generate a signal of a second voltage that is received by a waveform reshaping means 103 to stabilize the bias to the level of the second voltage. An RF receiver 101 converts the received RF modulated signal into a signal offset by a frequency deviation from the center frequency during a second period after the termination of the first period. The demodulation means 102 generates a demodulation signal of a first or third voltage according to the logical state of the received modulated signal. The waveform reshaping means 103 compares the received demodulated signal with the bias so as to generate a digital signal of a constant duty ratio. Application is to a battery saving circuit. <IMAGE>

Title: Magazine rack positional adjustment system
Inventor: TANI OKIE
IPC: H05K13/00
Filed: 1993-01-18
Abstract: An adjustment/transport system for a magazine rack (50) for containing a stack of printed circuit boards includes a conveyer line (122/123) for introducing magazine racks 50 into a production process. As a new magazine rack is introduced to the line, a positional adjustment mechanism (101-114) is active to position the magazine rack on the conveyer. In addition, the alignment of the magazine rack on the conveyer may be adjusted and a present accommodating width of the magazine rack may be detected and compared with an accommodating width required by a process being carried out on the conveyer. If the detected accommodating width of the magazine rack is other than the required accommodating width, the rack may automatically be adjusted by the adjustment mechanism prior to being added to the conveyer or at a predetermined position on the conveyer.   <IMAGE>

Title: Huffman decoder architecture for high speed operation and reduced memory.
Inventor: ALLEN JAMES
IPC: H04N7/30
Filed: 1993-04-26
Abstract: The speed of decoding a Huffman coded signal such as a still, moving or high definition image signal, is increased by memory efficient architectures. The coded signal contains coded units, each of which represents a block of pixels and comprises token bits (which define at least the length of the coded unit) and mantissa bits (of variable number). A shift register 24 holds a number of bits from, on average, a plurality of coded units, and each cell of the shift register is connected to an input of a memory 30 or look-up table to decode simultaneously the plurality of tokens. The total bit length of the coded units represented by the valid tokens is fed back to the shift register to feed through a whole number of coded units. This permits simultaneous decoding of a plurality of variable length coded units. <IMAGE>
