Title: Method and apparatus for encoding and transmitting at least a spatial part of a video sequence
Inventor: NAËL OUEDRAOGO
IPC: H04N19/70
Filed: 2017-03-20
Abstract: Encoding video data comprising at least one spatial part (for instance a region of interest or tile) by determining additional data for signalling in the bitstream an encoding constraint associated with the at least one spatial part of the video sequence, encoding the spatial part using the indicated encoding constraint and applying a hash function to each spatial part and signalling the result of the hash for each spatial part in the encoded video data. The encoding constraint is a set of coding dependency constraints related to the location of a predictor block, use of an interpolation or deblocking filter, or a particular motion vector prediction mechanism. The hash is preferably a cyclic redundancy check (CRC), md5 or checksum and is signalled in a supplemental enhancement information (SEI) message appended to the HEVC/H265 bitstream. In embodiments the signalling is done using a motion-constrained tile set (MCTS) hash SEI message as in Figure 18.

Title: Methods and systems for modulating energy usage
Inventor: Peter Konowalczyk
IPC: F24H9/20
Filed: 2021-08-02
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 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 and time periods may be set by a user, or by a machine learning algorithm to optimise for lowest cost. The control module may store upper and lower temperatures for plural users.

Title: Annular linear induction pump having axial guide vanes
Inventor: RUIJIE ZHAO
IPC: H02K44/06
Filed: 2021-01-07
Abstract: The present invention provides an annular linear induction pump having axial guide vanes. M axial guide vanes are circumferentially and uniformly arranged in a flow channel of the pump, m is the same as the number of external stators, and the length of the guide vanes is jointly determined by the number of the external stators, the central radius of the flow channel, the Reynolds number of a magnetic field and the wave number of a traveling wave magnetic field. The axial guide vanes can obviously reduce the influence of circumferential non-uniform disturbance of a magnetic field and a flow field on the stability of the flow field, such that the flow stabilizing effect is achieved, and the flow stability of a large-flow pump under eccentric working conditions is greatly improved.
