Patent GB-2593257-A (GB)
Title: Cyber-security protocol
Inventor: MICHAEL MAASS
IPC: H04L29/08
Filed: 2020-12-03
Abstract: A cyber-security protocol for validating messages being exchanged between two devices of an autonomous vehicle includes the independent generation of multiple encryption or session keys by both devices. The encryption keys are generated based on a random number provided by each device 1602. In some embodiments, the random numbers can be accompanied by a shared secret key installed on both devices that can help prevent an unauthorized device from creating a shared set of encryption keys with one of the devices. A first device receives a series of three messages 1604, 1606, 1610 from a second device, each message including a hash generated using one of the encryption keys and a message sequence counter value. This helps prevent the injection of previously transmitted messages as a means of disturbing operation of the autonomous vehicle. The first device then authenticates the second and third of the messages 1608, 1612. The three messages may be received across a first channel and the second device may transmit messages to the first device using a second, discrete channel. The devices may perform independent rekeying operations for both channels. The first device may be a velocity sensor or object detection sensor.

Filed: 2022-06-28
Abstract: Aspects of the present disclosure relate to an apparatus. Instruction receiving circuitry receives, as part of a program flow, a branch instruction, said branch instruction identifying a function. Instruction authentication circuitry determines, based at least in part on the function, an instruction authentication value. The instruction authentication circuitry then combines the instruction authentication value with the branch instruction to produce an authenticatable branch instruction. Branch circuitry authenticates the authenticatable branch instruction based on a function authentication value. Responsive to a successful authentication of the authenticatable branch instruction, the branch circuitry executes a jump in the program flow to said function.

Title: Identifying one or more quantisation parameters for quantising values to be processed by a neural network
Inventor: SZABOLCS CSEFALVAY
IPC: G06N3/084
Filed: 2022-06-30
Abstract: A neural network (e.g. Deep Neural network DNN) model has quantisation blocks for quantising sets of values (e.g. input activations, weights, biases) input to a layer of the NN into a respective fixed-point number format defined by one or more quantisation parameters (e.g. bit widths) for implementing the NN in hardware (e.g. for configuring a NN accelerator). Quantisation parameters are identified by: determining an output of the model of the NN responsive to training data; determining a cost metric that combines an error metric (e.g. mean squared error or SoftMax function) and an implementation metric representing the hardware costs of implementing the NN based on the quantisation parameters and being dependent on, for each of a plurality of layers of the NN, a sum or product of a first contribution representing an implementation cost of an output from that layer and a second contribution representing an implementation cost of an output from a layer preceding that layer; back-propagating a derivative of the cost metric with respect to at least one quantisation parameter to generate a gradient of the cost metric for the at least one quantisation parameter; and adjusting the at least one quantisation parameter based on the gradient.

Abstract: Techniques are disclosed relating to context switching in a SIMD processor. In some embodiments, an apparatus includes pipeline circuitry configured to execute graphics instructions included in threads of a group of single-instruction multiple-data (SIMD) threads in a thread group. In some embodiments, context switch circuitry is configured to atomically: save, for the SIMD group, a program counter and information that indicates whether threads in the SIMD group are active using one or more context switch registers, set all threads to an active state for the SIMD group, and branch to handler code for the SIMD group.

Title: A thermal management system
Inventor: Ananthan Rajagopalan
IPC: F02D41/04
Filed: 2022-10-18
Abstract: A thermal management system controls cooling of an engine system during shutdown, the engine system being configured to provide power to a working machine. The thermal management system comprises a controller to receive a signal indicative of an engine shutdown command and to derive, infer or receive a temperature parameter of the engine system (e.g. exhaust temperature, coolant temperature). The controller is configured to determine whether the temperature parameter exceeds a first predetermined threshold. In a first aspect, if the first predetermined threshold is exceeded when the engine shutdown command is received the controller is configured to signal the progressive reduction of a speed of the engine (see figures 3a-3b for stepped, linear and exponential reduction of engine speed) prior to issuing a signal to shutdown the engine, thereby cooling the engine system prior to engine shutdown. In a second aspect, if the first predetermined threshold is exceeded when the engine shutdown command is received the controller determines whether engine speed exceeded a speed threshold within a given time period prior to the engine shutdown command being received. If so, the controller signals the engine to run for an extended period after receipt of the engine shutdown command.

Abstract: A method of decoding video data from a bitstream where the video data has multiple slices. The bitstream has a Picture Header (PH) 608 for syntax elements to be used when decoding a picture comprising one or more slices, and a Slice Header (SH) 610 for syntax elements to be used when decoding a slice. When decoding, syntax elements are parsed from the PH to indicate whether Luma Mapping with Chroma Scaling (LMCS) and/or Scaling List are enabled for the picture; and when enabled, syntax elements relating to the LMCS APS ID and/or Scaling List APS ID are parsed from the PH. When LMCS are enabled, syntax elements are parsed from the SH indicating whether the decoding tool of LMCS is to be used for the slice immediately after a syntax element related to an ID of ALF APS in the SH. When Scaling List is enabled syntax elements are parsed from the SH indicating whether the decoding tool of Scaling List is to be used for the slice, immediately after the at least one syntax element indicating whether the decoding tool of LMCS is to be used, and prior to syntax elements related to one or more decoding tools.

The invention relates to a control method for improving the positioning precision of a pan-tilt camera. The control method comprises: firstly, initialization is performed; a panoramic image of an application scenario is displayed on a display screen of a computing platform, a user selects a region of interest in the panoramic image of the application scenario, an image of the region of interest is stored as a target image, and the user selects one target image from a plurality of target images as a target to be rotated. The beneficial effects of the invention are that: control is performed on a software layer, so there is no need to modify the hardware elements of a traditional camera, the target can be accurately positioned through software operation even if the rotating axis of a camera is inaccurate, and there is no need to replace camera devices. Thus, hardware deployment costs can be greatly reduced, and the service life of camera hardware is prolonged. The present invention allows the user to balance the speed and precision of panorama composition and matching calculations based on the actual situation. The present invention is highly flexible.
