The drive member comprises engaging pockets defined by spaced apart rollers (8) joined by rigid connecting members, a first pocket 401 defined by first 32 and second 34 rollers adjacent to one another, a second pocket 402 defined by the first roller and third roller 322 and third pocket 403 defined by the second roller and fourth roller 422. The third roller is adjacent the first roller and the fourth roller is adjacent the second roller. A first articulation angle a1 is formed by the connecting member connecting the first and second rollers and the connecting member connecting the first and third rollers. A second articulation angle a2 is formed by the connecting member connecting the first and second rollers and the connecting member connecting the second and fourth rollers. The magnitude of the first articulation angle when the first, third and fourth rollers are in contact with a tooth is different to the magnitude of the second articulation angle when the first, second and fourth rollers are in contact with a tooth. In use only every other engagement pocket may engage with a tooth.

Patent GB-2606040-A (GB)
Title: Implementation of discrete Fourier-related transforms in hardware
Inventor: Sandra La Mantia
IPC: G06F17/14
Filed: 2021-10-18
Abstract: Discrete Fourier transforms are carried out by fixed function circuitry to perform convolution operations. Convolution kernel derived from a weight matrix representing a matrix multiplication may be used to execute a discrete Fourier related transform. Input data containing a real value input tensor may undergo a fast Fourier transform. Another dimension of the input tensor may be Fourier transformed to produce a fast Fourier transform of the input data. A short time Fourier transform may be implemented using convolution kernels where strided convolution operations correspond to an amount of overlap between overlapping parts of input data. The convolution kernel may be generated by reshaping of permutating dimensions of a weight matrix, before input data is obtained. A second tensor comprising imaginary parts of values may also undergo discrete Fourier transform, and a concatenated tensor produced. Further splitting the convolution output may provide further multiplied tensors.

Title: Haircare appliance
Inventor: BARTOSZ SLAK
IPC: A45D20/12
Filed: 2021-12-23
Abstract: A haircare appliance (100, fig 1) arranged for detecting moisture content of hair comprises a processing element, at least one light emitting element 204 adapted to emit at least two wavelengths to irradiate a portion of hair to be treated, and a spectral sensor element 206. The sensor element is adapted to receive a sensor reading from an acquisition region 208 of the irradiated hair and generate a sensor signal dependent on this. Based on this signal, the processing element determines a moisture content of at least the irradiated portion of the hair 208. Further disclosed appliances do not require the light 204 to emit two wavelengths or the sensor 206 to be a spectral sensor, but also include an accessory which is either attachable to and/or detachable from a main body of the appliance, or integrally connected with the main body.
Patent GB-2615769-A (GB)
Title: Synchronization of frequency measurements in a demand response system
Inventor: Stef Peeters
IPC: G01R29/18
Filed: 2022-02-17
Abstract: A method of determining a synchronization offset for measurement data relating to an electrical power supply network. First 202 and second 204 sets of measurement data are received from first source and second sources (102, 110, figure 1). Each data set includes measurements of an electrical parameter, e.g. frequency or voltage measured at the respective source, together with time information indicating the times of the measurements. The second data are sampled with a reference clock (111, figure 1), while the first data are sampled with a less accurate clock (103, figure 1). A plurality of different time shifts are applied 208 to the second data and a correlation measure 210 is determined between each of the time-shifted second data and the first data. The highest correlation value 212 indicates the true value of the synchronisation offset between the first and second measurements. This synchronization offset is used 214 to correct time information in measurement data from the first source.

Patent GB-2608908-A (GB)
Title: Optical system with waveguide
Inventor: ANDRII VOLKOV
IPC: G02B27/01
Filed: 2020-09-21
Abstract: An optical system includes a waveguide 120 with opposing first and second major surfaces, input optics and an image source 110. The input optics includes an input mirror 136 and an in-coupling diffraction grating. The input mirror is proximal the first waveguide surface and the image source is proximal the waveguide second surface so that light from the image source passes through the waveguide, is reflected by the mirror and is coupled into the waveguide by the in-coupling diffraction grating. The waveguide may be cylindrical and the first and second opposing major surfaces may be concentric opposing surfaces defining a common cylinder axis. The input optics may receive light from the light source, reflect and diffract the light into the waveguide so that all rays originating from the same image source pixel are incident on a surface of the cylindrical waveguide at the same angle relative to the surface normal and at the same angle relative to a plane normal to the cylinder axis, at each point of incidence. The in-coupled light may thus retain its direction angle as it propagates along the cylindrical waveguide. An optical display device and a head mounted display may include the optical system.
