Title: Back-up and restoration of data between volatile and flash memory
Inventor: KELVIN WONG
IPC: G11C16/10
Filed: 2016-07-12
Abstract: Back up data to flash memories are organized into stripes comprising pages with the same block and page address across all flash-memory devices, dies, planes. Planes have data transfer caches for when the memory is busy performing array operations. Cache program commands to three stripes are sent simultaneously (104). The stripe also indicates the handling of cache program commands. If a grown bad block is encountered (106) whilst saving a stripe, the stripe is re-written (116) to the next available page address, avoiding the bad block. Metadata of known and grown bad planes (102, 103) are used to determine the planes where to send cache program commands (104) avoiding bad planes for current logical block addresses (LBA). The metadata refer to the planes having bad blocks at a block address. Cache program commands to three stripes allow data transfer for a second page program while a previous one is being completed.

Title: Method and apparatus for detecting a laser
Inventor: Christopher David Burgress
IPC: H04N7/18
Filed: 2017-12-08
Abstract: In a laser detector apparatus and method, a pixel (sensor) array 3 is arranged behind a lens arrangement 4 such that any point-like distant (distal) objects 9 (in general, effectively at infinity) are out of focus at the pixel array, giving rise to a characteristic out of focus (unfocussed) image on the array. Any substantially point-like proximal (near) light sources 10 result in a different image. The (e.g., binary) images are evaluated by a computer processor to detect distal laser light sources by identifying the characteristic out of focus images, disregarding different images and their associated light sources. Identified characteristic image features may be of known size and shape (e.g. circular spots of known diameter/width). Thus, distant laser threats may be distinguished from nearby bright objects, whilst protecting the pixel array from powerful laser sources - as laser energy is not focussed to a point, it is less likely to damage the pixel array. The laser wavelength may be determined from the ratio of colours in the laser spot image. Laser sources across a wide range of brightness, and also multiple laser sources, may be detected.

Title: Directional shift control in vehicles
Inventor: CHRISTOPHER WYNKOOP
IPC: F16H61/16
Filed: 2018-08-30
Abstract: A method of controlling gear selection in a transmission, e.g. powershift transmission, of a vehicle in response to a directional shift (e.g. forward to reverse) requested by an operator, e.g. via a joystick. The method compares a current transmission output speed with a predetermined direction shift threshold transmission output speed. If the current transmission output speed is less than or equal to the predetermined direction shift threshold transmission output speed, the transmission shifts from an initial first direction gear to a same second direction gear, or a next highest second direction gear. If the current transmission output speed is greater than the predetermined direction shift threshold transmission output speed, the direction shift is inhibited until the current transmission output speed slows to less than or equal to the predetermined direction shift threshold transmission output speed. Reference is also made to a control system for controlling gear selection to manage directional shifts in vehicles and to a vehicle the control system.

Title: Low precision efficient multiplication free convolutional filter bank device
Inventor: BRENDAN PATRICK RUFF
IPC: G06F7/544
Filed: 2019-01-29
Abstract: A convolutional neural network CNN comprises banks of convolutional filters and input, output, and filter coefficients represented with low-precision significands, preferably 3 or 4 bits, for which no loss of accuracy is found This allows a simple look-up table to replace multiplications in convolutional CNNs for all possible product values of significands of input tensors and filter coefficients. Therefore, the accumulated result across coefficients of each filter is efficiently formed by summing the shifted and filter centre aligned output of this look up table. Implementing convolutional filtering is simplified with less computational cost than devices employing higher-precision and multiplication. Implementations comprise creating and sharing low-precision and padded significand product intermediate results 37, which are indexed by the filter depth index and shifted to from a filter center aligned 2D tensor 26. Tensor 26 is accumulated and reformatted to higher precision (11). Input tensors can be input 2D slices or tiles.
