Patent GB-2315617-A (GB)
Title: Identifying battery type and brand
Inventor: BARKAT SHAKIL H
IPC: H01M10/44
Filed: 1997-07-01
Abstract: A battery 101 has a memory 402 storing data identifying the battery type (NiCd, NiMH, alkaline, or Li-ion) and brand and also storing a multi-character message. The type and brand data and the message must match predetermined data before the battery can be used or charged, whereby only batteries which are known to be reliable and safe can be used or charged. A portable apparatus, particularly a portable cellular radio telephone, is powered by removable main and auxiliary batteries 101, 102 having respective memories 402, 410 storing such data. The apparatus is powered down if it detects that a battery with non-matching data is attached, and charging of a battery by an internal charger circuit 444 (or by an external charger) is terminated if the battery does not have the matching data. When the apparatus is in an operating mode it is powered by an external supply 430, if present. If the supply 430 is absent, the apparatus is first powered by the auxiliary battery 102 and then by the main battery 101 when the auxiliary battery voltage has dropped to a predetermined level. The charging circuit 444 first charges the main battery from the external supply 430 for a predetermined time at a regulated current, as determined by data in the memory 402. The auxiliary battery 102 is then similarly charged, followed by maintenance charging of both batteries. A controller 306 detects the presence of either battery 101, 102 by a voltage drop across respective thermistors 406, 414 therein.

Title: Using simulations to decide when to stop production line equipment for inspection
Inventor: SAKAKIBARA TAKAKO
IPC: G06F19/00
Filed: 1997-08-28
Abstract: The number of work pieces handled by a production line machine to be tested is simulated and possible inspection periods are recognised by detecting this number falling below a threshold value. The output of the production line is then simulated assuming that the line will stop for one of the recognised periods and that period becomes a permissible inspection period if the overall output of the production line for the entire simulation does not fall below a required value. If there are several permissible periods then the one yielding the highest production line output for the simulation period is chosen to become the actual inspection period. If several of the machines on the production line are to be stopped for inspection then an inspection period is chosen on the basis of the permissible periods indicated by simulation having regard to all the machines to be inspected.
Patent GB-2329557-A (GB)
Title: Viterbi decoder using pre-calculated look-up tables
Inventor: JAKOBSEN KEN
IPC: H03M13/23
Filed: 1997-09-19
Abstract: Data for transmission may be convolutionally encoded and punctured prior to transmission. The invention relates to a method and apparatus for decoding such data. In accordance with the invention, a table of error metrics is prepared when a given group (Gt) of n bits is received at a particular time (t). The error metrics (Mti) are calculated for comparisons of the n bits received with each possible permutation (Pi) of n bits. These error metrics (Mti) are placed in the metric table. Next a look-up table (Tt) is consulted which lists each state change (Sj) which the encoder could have undergone at the particular time (t) together with the permutation (Pi) of bits which would have been produced by the encoder for that state change. The look-up table (Tt) is particular to the puncturing scheme which the encoder uses at the particular time (t). The metric table is then used to add to the look-up table (Tt) the error metric (Mti) appropriate to each state change (Sj) in the table (Tt). These error metrics are then used to update the cumulative metric of the decoder. The look-up table (Tt) may be one of a set of such tables with different tables being used in dependence on the particular puncturing scheme being used.

Title: Subthreshold conduction sigmoid ramp converter for a neural network
Inventor: HAN IL SONG
IPC: G06N3/063
Filed: 1997-10-02
Abstract: Capacitor C is initially charged by the input voltage or current via switch S1 and then switch S2 is closed so that the capacitor voltage is modified by the diode-connected MOS transistors M1 and M2, the final capacitor voltage being a sigmoid function of the initial capacitor voltage. The flat portions of the curve occur where the initial voltage is clamped by one of the transistors to a high or low level, the linear portion occurs when neither transistor conducts, and the transition regions A and B (figure 2b) occur when one transistor conducts in the subthreshold region. Because subthreshold MOS conduction has an exponential character, the shape of the transition regions A and B (figure 2b) may be described as a function of an exponential function.

Title: Dual subframe quantisation of spectral magnitudes
Inventor: HARDWICK JOHN CLARK
IPC: G10L25/93
Filed: 1998-03-16
Abstract: A speech signal is digitized into digital speech samples that are then divided into subframes 300,305. Model parameters that include a set of spectral magnitude parameters Mo.....Me that represent spectral information for the subframe are estimated for each subframe. Two consecutive subframes from the sequence of subframes are combined into a block and their spectral magnitude parameters are jointly quantized 320. The joint quantization includes forming predicted spectral magnitude parameters from the quantized spectral magnitude parameters from the previous block, computing the residual parameters as the difference between the spectral magnitude parameters and the predicted spectral magnitude parameters, combining the residual parameters from both of the subframes within the block, and using vector quantizers to quantize the combined residual parameters into a set of encoded spectral bits. Redundant error control bits are added to the encoded spectral bits from each block to protect the encoded spectral bits within the block from bit errors. The added redundant error control bits and encoded spectral bits from two consecutive blocks 330 are combined 340 into a 90 millisecond frame 350 of bits for transmission across a satellite communication channel.
Patent GB-2329785-A (GB)
Title: Encoding a binary shape signal
Inventor: CHO SUNG-RYUL
IPC: H04N19/00
Filed: 1998-04-27
Abstract: Apparatus, for use in context-based arithmetic encoding of a binary shape signal, generates a bordered block having a border of width D around a target block. In order to produce the bordered block, the apparatus first calculates a weighted mean for each of the border pixels in the bordered block PS1 by using N neighboring pixels A1 to A4 for pixel P1. Each of the weighted means is compared with the larger binary value to thereby assign either the larger or the smaller binary value to each of the border pixels. After the binary value to be assigned to each of the border pixels is determined, the apparatus constructs the bordered block based on the binary values assigned to the border pixels and the binary shape signal.
