Title: A method and apparatus for detecting defective cells within a battery
Inventor: TIMOTHY JOHN HUGHES
IPC: G01R31/396
Filed: 2019-05-02
Abstract: A method of detecting defective cells in a battery by measuring a characteristic of a plurality of cells as a time-series at multiple times, arranging results for a certain time in a histogram, comparing histograms of different times and identifying cells results that have changed positions or that assume extreme positions in the distribution as deteriorating. The amount a cell needs to move to qualify as degrading may be based on a threshold in sigma, percentage change in peak value or parameter value or position within a ranking according to magnitude. Cells identified as deteriorating may be replaced or repaired. The characteristic measured may be open-circuit voltage, internal resistance, cell current, charge capacity, state of charge, temperature, or an electrochemical parameter. Deteriorating cells may be identified when the distribution of a histogram changes from a normal to a log-normal distribution. The method may be executed by an apparatus with monitoring equipment for measuring cell parameters, a processor to generate a histogram, a memory, and a comparison unit that outputs an indication of cells that are identified as deteriorating.

Title: Method and apparatus for encoding and decoding a video bitstream for merging regions of interest
Inventor: ERIC NASSOR
IPC: H04N19/88
Filed: 2019-12-17
Abstract: Encoding video data comprising frames into a bitstream of logical units, where the frames (204, fig 2) are spatially divided into frame portions (205, 206, fig 2), the frame portions are divided into subportions, and the subportions may be grouped. The subportions may be rectangular tile groups or slices (203, fig 2); or alternatively, the subportions may be layers (202, fig 2). The quantisation parameter (QP) information associated with each subportion is determined. The group of subportions are encoded into a first logical unit and the association between an index of the subportions and corresponding QP information is encoded into a second logical unit. A merged bitstream 602 may include a Picture Parameter Set (PPS) 620 which may include a default initial QP value (init_qu_minus26) and an association table comprising QP offset values (tile_group_qp_offset). Alternatively, instead of the offset, the initial QP value may have a different default initial QP value associated to each subportion. Alternatively, the tile_group_qp_offset parameter only applies for a subset of subportions. The present invention solves the quantisation parameter delta problem when merging subportions from different bitstreams without amending the tile group NAL unit by introducing QP information associated with each subportion in a parameter set.
