Title: Amplifiers
Inventor: ANGUS BLACK
IPC: H03F3/217
Filed: 2021-05-28
Abstract: A class-D amplifier that has a first feedback path Sfb1 taken from the output Sout and a second feedback path Sfb2 taken from a digital section of the forward signal path. In a first mode a combiner 203 selects feedback from the first feedback path and in a second mode the combiner selects feedback from the second feedback path. When operating in the second mode, a calibration module 204 reduces any DC offset in the first feedback path. A controller 201 may select the operating modes and use variable gain elements 202 to transition between the first and second modes over a transition period using inverse gains. While operating in the second mode the calibration module may apply a zero-reference voltage to the first feedback path, via a switchable reference REF or via the amplifier output Sout, to determine a DC offset and adjust a compensation signal Comp or Scal. The circuit may operate a start-up sequence where the second mode is selected (t0-t1,Fig.3) so the first feedback path can undergo calibration before the first mode is selected (t2-t3,Fig.3). Calibration can also occur at a later time (t4-t6,Fig.3). The amplifier circuit may drive an audio output transducer.

Title: Methods and systmes for modulating energy usage
Inventor: Peter Konowalczyk
IPC: F24H9/20
Filed: 2022-02-07
Abstract: A hot water system providing heated water to one or more water outlets (e.g. shower) comprises a control module and a heat pump that heats a medium (e.g. paraffin wax) in a thermal energy store, the store being used to heat water for the outlet(s). The control module modulates energy consumption of the system so that overall energy usage is reduced. When a water outlet is opened/turned on, the module controls the system so that the temperature of water at the outlet alternates between an upper temperature (e.g. 41°C) and a lower temperature (e.g. 37°C). The upper and lower temperatures are determined based on an energy consumption target, which may be set by a user or predetermined by factory setting (e.g. based on energy consumption considerations and/or health benefit considerations). The upper temperature may be maintained for a first time period (e.g. 1 minute) before the lower temperature is used for a second time period (e.g. 1 minute). The upper and lower temperatures could be profiled to specific users, or optimized through machine learning algorithms and tariff costs. The control module may store upper and lower temperatures for plural users.

Title: Low complexity enhancement video coding
Inventor: GUIDO MEARDI
IPC: H04N19/30
Filed: 2020-03-18
Abstract: A bitstream for transmitting enhancement residuals plane(s) suitable to be added to a set of preliminary pictures obtained from a decoder reconstructed video, comprises a decoder configuration for controlling a bitstream decoding process, and encoded enhancement data comprising encoded residual data representing differences between a reference video frame and a decoded version of the video frame (as per LCEVC / MPEG 5). The decoder configuration comprises a transform_type variable, wherein a value of the transform_type variable indicates a type of transform to be applied to transform coefficients in the decoding process. The enhancement coding may operate on top of a base layer, which may provide base encoding and decoding. Spatial scaling may be applied across different layers. Only the base layer encodes full video, which may be at a lower resolution. The enhancement coding instead operates on computed sets of residuals. The sets of residuals are computed for layers, which may represent different levels of scaling in one or more dimensions. Encoding / decoding tools are described, which may involve applying transformations, quantization, entropy encoding and temporal buffering. At an example decoder, an encoded base and enhancement stream(s) may be independently decoded and combined to reconstruct a video.
