Title: Stairlift and method of operating a stairlift
Inventor: GAVIN PUGH
IPC: B66B9/08
Filed: 2018-10-18
Abstract: A stairlift includes a stairlift rail 11, a carriage 15 mounted on the rail 11, a chair 20 pivotally mounted on the carriage 15, at least one motion sensor 30, 114, 27, a chair levelling motor 26 operable to pivot the chair 20 relative to the carriage 15 as the carriage 15 traverses the rail 11, memory and a control system. The control system is operable at step 414 to store a record (310/320 fig. 8) of an undesirable movement of the chair 20 such as chair levelling oscillations or overall chair angular lag from the upright position. The record (310/320 fig. 8) includes an indication of the position along the rail at which the undesirable movement occurred (336 fig. 8). The control system is also operable, during a subsequent traversal of the rail 11 by the carriage 15, to apply a remedy to attempt to prevent a reoccurrence of the undesirable movement of the chair at the position indicated in the record (310/320 fig. 8). The control system is further operable to determine at step 416 whether the undesirable movement of the chair reoccurred and, if it did reoccur, to reduce the speed of the carriage 15 during a subsequent traversal of the rail 11. Remedies may include using an anti-oscillation unit (122 fig. 4) to adjust or block the output from a low gain unit (116 fig. 4) forming part of a control signal (102 fig. 4) or to dynamically modify a primary signal (108 fig. 4) using a slow filter (124 fig. 4) receiving a signal from a gyroscopic gain unit (120 fig. 4) or to reduce the speed of the carriage 15 along the rail 11.

Title: Image demosaicing
Inventor: GARETH JOHN MCCAUGHAN
IPC: H04N9/04
Filed: 2019-06-26
Abstract: Image data from an image sensor has a pixel value for each pixel of the sensor. The image sensor has a colour filter array (e.g. Bayer CFA) with one colour filter over each pixel. Demosaicing determines a first colour value of a target pixel (covered by a filter of a second colour) and includes compensating for chromatic aberration by correcting a position of the target pixel or a neighbouring set of pixels which are covered by a filter of the same first colour (e.g. by applying an x and y offset to the position) and spatially interpolating between pixel values of the neighbouring pixels (e.g. using bilinear interpolation). The first colour value is adjusted based upon an image brightness variation in a region around the target pixel, for example by convolution over pixels in the region. The adjustment may be modified based on the chromatic aberration position correction.

Title: Method and apparatus for encoding and decoding a video bitstream for merging regions of interest
Inventor: NAËL OUEDRAOGO
IPC: H04N19/88
Filed: 2020-01-13
Abstract: Encoding and decoding video data comprising pictures into a bitstream of logical units, where the pictures are divided into picture portions and the picture portions are spatially divided into sub-portions. A parameter set applying to a sub-portion is determined, a first identification information of the determined parameter set is determined, and a second identification information associated with the sub-portion is determined. A parameter set identifier is determined based on the first and second identification information. The bitstream has a first, a second, and an additional logical unit. The first logical unit is the sub-portion which may be a Tile Group encoded into a VCL NAL unit. The second logical unit has the parameter set for the sub-portion and the parameter set identifier. The additional logical unit has the association between the sub-portion and the second identification information. The present invention solves the APS or PPS identifier collision problem when merging tile groups or sub-pictures from different bitstreams without amending the tile group structure by introducing a second identification information associated to each tile group in a parameter set of the bitstream.

IPC: H01M8/2483
Filed: 2018-04-18
Abstract: Fuel cell stack assemblies 100 having a positive end plate 200 and a negative end plate 300 are described. The end plates are formed from a plurality of separate components including a central structural element (220, 320; figs 2, 3), covered by an end plate cover (210, 310; figs 2, 3) on one face and an end plate manifold for fluid flow (230, 330; figs 2, 3) on its other face. The positive and negative end plates are provided on either end of a stack of cathode plates 150­1-150n and fuel cell assemblies 2501-250n. The positive end plate has airflow channels with straight walls from a first side edge to an opposing side edge, and the negative end plate has airflow channels of a sinusoidal wave shape running from a first side edge to an opposing side edge. This arrangement ensures that relatively less heat exchange takes place at the positive end plate since it is adjacent to a cathode plate 150n, while relatively more heat exchange takes place at the negative end plate since it is adjacent to a heat-generating fuel cell assembly 2501.

Filed: 2019-03-14
Abstract: A method of trapping ions in an ion trapping assembly comprising an ion trap (100, Fig. 2) and an ion cooling device, e.g. a collision cell (120), comprises: applying an RF trapping voltage having a first amplitude V1 to the ion trapping assembly to capture introduced ions within a first range of m/z ratios; cooling said trapped ions; and then reducing the amplitude of the RF voltage to a second, lower amplitude V2 to reduce the low mass cut-off (LMCO) of the ion trapping assembly; and trapping, at said second RF amplitude, introduced ions within a second range of m/z ratios, the lower mass limit of the second mass range being below the LMCO when the first RF amplitude is applied. Further intermediate RF trapping amplitudes (V3–V5, Fig. 6) may be applied to the trapping assembly to successively reduce the LMCO and the lower mass limit of introduced ions that are trapped therein. The same effect may also be achieved by increasing the frequency of the RF trapping voltage.
