Title: Balance circuits for battery cells
Inventor: GUOXING LI
IPC: H02J7/00
Filed: 2018-04-09
Abstract: A balance circuit 200A for a set of battery cells 220 includes a set of switch circuits 212A and control circuitry 202A coupled to the switch circuits. Each switch circuit of the switch circuits is coupled to a corresponding battery cell of the battery cells, and enables a bypass current to flow out from a positive terminal of the corresponding battery cell if the switch circuit is turned on. The switch circuit includes a first switch QN11, QN21, QN31, QN41 having a first diode, and includes a second switch QN12, QN22, QN32, QN42 having a second diode reversely coupled to the first diode. The second switch disables the bypass current if the second switch is turned off. The control circuitry balances the battery cells by controlling the switch circuits. The switches may be MOSFETs. The control circuit may monitor the status of each battery and balance the cells based on a comparison to a reference voltage.

Title: Vehicle control method and apparatus
Inventor: Robin Boyd
IPC: B62D15/02
Filed: 2018-04-24
Abstract: A control system 1 for a host vehicle 2, comprising a processor operable to track a target vehicle 3 and generate a target vehicle trace, correlate a host vehicle location and/or trajectory with the target vehicle trace, and output a deviation signal if the correlation between the host vehicle and the target vehicle exceeds a predefined deviation threshold, or output a correlation signal if the correlation falls within the predefined threshold. The predefined threshold may be a divergence in steering angle between the two vehicles, or a distance between their current locations. Sensors could be provided on the host vehicle as a means of image capture to generate the target vehicle trace. Such sensors could include LIDAR, radar, or ultrasonic. Associated methods for operating system and non-transitory computer-readable mediums for storing the method are also described.

Title: Ultrasound imaging probe
Inventor: ADRIEN DESJARDINS
IPC: A61B8/12
Filed: 2018-06-15
Abstract: Ultrasound (US) imaging probe 10 comprises a light guide, e.g a multi-mode transmission fibre 130. An optically absorbent material 135 e.g. a polydimethylsiloxone coating generates ultra-sonic beam 171 via the photo-acoustic effect. A portion of probe 10 such as the absorbent material (figure 2B), fiber 130 or reflector turns, e.g. at 60Hz, rotating the ultra-sonic beam while it projects substantially perpendicularly to longitudinal axis z. The beam reflects from structures in tissue 30, e.g. an atrial tumour. Ultrasound waves then impinge on receiver 155, e.g. a concave Fabry-Perot optical cavity, interrogation light in fibre 150 being reflected according to cavity separation and thus ultra-sonic waves, giving a volumetric US image. The rotation angle is possibly determinable using cross-talk between transmitter and receiver, and a double-clad fibre may be used. The probe may be used in medical instrument 100 such as a cannula or guide-wire, the small diameter supporting intra-vascular use.

Title: Video sequence processing
Inventor: MICHAEL JAMES KNEE
IPC: G06T7/246
Filed: 2012-04-04
Abstract: In an apparatus for motion vector assignment partial filters are applied to two or more regions 402-409 of pixel-to-pixel dissimilarity values between a plurality of video frames in a sequence. Outputs of the partial filters are combined to estimate motion between the plurality of video frames. The partial filters may take a maximum or a mean of the pixel difference values in the regions. The regions may define line segments or octants arranged radially around a pixel 401 for which the motion is to be determined. The outputs may be combined by a non-linear operation, for example taking the minimum from diametrically opposed regions. The apparatus may be used during motion searching and the filtering may assess how well-matched pixels in regions near a pixel are to regions near a point indicated by a candidate motion vector.

Title: Configuring cryptographic systems
Inventor: DEVEN J ANTHONY
IPC: G06F21/31
Filed: 2016-07-29
Abstract: This application aims to provide an improved way of updating the cryptographic systems of aircraft 400. It does so by first generating a cryptographic key configuration (CKC) on a remote terminal that is separate from the aircraft. This is done by first receiving data that is indicative of a user specifying a CKC action 402, which includes modifying a cryptographic ignition key. It then accesses a database that stores the cryptographic information 404, and generates the CKC 406. The CKC is then transferred to a removable data cartridge via a connector with one or more pins that provide a mechanical and an electrical connection, or storage device 408. The user can then engage this device with an avionic transfer system 410, and the avionic transfer system is then automatically configured based on the CKC 412, where the configuration is transmitted via the one or more pins of the connector.

IPC: H04N19/82
Filed: 2019-06-21
Abstract: A method of controlling an Adaptive Loop Filter (ALF), for filtering an image portion made up of a plurality of blocks. ALF parameters are obtained which define filters that are applicable to blocks of the image; and a limit is imposed on a maximum number of filters usable for filtering the blocks of the image portion.
