Title: Sampling for feature detection
Inventor: TIMOTHY SMITH
IPC: G06K9/46
Filed: 2018-04-05
Abstract: The invention relates to a computer-implemented method for generating a feature descriptor 1016 for a location in an image suitable for use in performing descriptor matching when analysing the image. The method comprises determining a set of samples 1012 characterising a location in an image by sampling scale-space data 1006 representative of the image, the scale-space data comprising data representative of the image at a plurality of length scales. The method then generates a feature descriptor in dependence on the determined set of samples. The scale-space data could comprise pre-filtered data, possibly low-pass or Gaussian filtered, in the form of an image pyramid (800) or cone. The different length scales, in which structures are successively suppressed, or smoothed out, at progressively larger length scales enables structures at coarser (longer) length scales to be obtained from corresponding structures at finer (shorter) length scales. The sampling process could use a descriptor pattern, e.g. in the shape of a ring, circle or polygon, or a plurality of concentric such shapes (see Fig. 8C). Independent claims are also included for a system and a method of manufacture of such a system.

Title: Methods and apparatuses for vehicle wading safety
Inventor: SCOTT VINCENT MYERS
IPC: G01F23/00
Filed: 2018-05-22
Abstract: Techniques and examples pertaining to vehicle water wading safety are described. A Processor implementable to a vehicle approaching a water body receives topographic data related to the water body from one or more above-water or under-water sensors. The processor determines a top surface and a bottom profile of the water body, and calculates one or more critical trajectories of water-sensitive components of the vehicle if the vehicle is to wade through the water body by traversing the bottom profile. The processor may then determine the wading safety based on the critical trajectories and the top surface of the water body. The processor may further determine a wading route, and autonomously drive the vehicle to wade the water body via the optimal wading route.

Title: Reverse polarity protection circuit for a DC-DC converter
Inventor: FRANK WARNES
IPC: H02H11/00
Filed: 2019-03-21
Abstract: A reverse polarity protection circuit 200 for a DC-DC converter having an inductive component. When the DC-DC converter is connected to a power supply with correct polarity the inductive component of the converter receives power via a body diode of a protection switch 207. Once the inductive component begins to charge and discharge as controlled by a driving switch, the protection switch turns on and allows full power to be provided to the inductive component. When the DC-DC converter is connected with reverse polarity, a clamping switch 209 fed by the power supply turns on and connects a control input of the protection switch to ground, turning off the protection switch. The clamping switch is protected by a switch protection device 230 configured to lower the voltage difference between a control input of the clamping switch and an input of the clamping switch.
