Patent GB-2543107-A (GB)
Title: Adaptive filter control
Inventor: ZHENGYI XU
IPC: H03H21/00
Filed: 2015-11-24
Abstract: A sound processing circuit 203 (for eg. speech enhancement on a multi-microphone device 200) comprises two circuits 204 & 210 with adaptive filters 205 & 211 for receiving input signals x and y. The first calculates an error between the second input signal y and the output of the first adaptive filter (eg a noise filter) Ty, and outputs an error signal Ny to the second adaptive filter (eg. a noise cancellation filter) which subtracts an output of the second adaptive filter Nx from the first input signal x to generate a final output signal Tx. The adaptation of the filters is controlled 207 based on a magnitude coherence Mcoh(k,l) between the first and second input signals. This will be small when eg. a user is not speaking, providing slow adaptation, but converges more quickly when target speech is detected (ie. the two microphones are picking up very different signals)

Title: Transmitting and receiving data using polar codes
Inventor: Michal Palgy
IPC: H04L1/00
Filed: 2017-05-05
Abstract: A method to transmit and receive data over a physical channel using a polar code. A data block of D data bits for transmission has a scrambling pattern applied based on S additional data bits to be transmitted as well. Error detection data is also included which may comprise a cyclic redundancy check (CRC). At the receiver one or more hypotheses are generated as to which scrambling format has been applied to the data block. Each hypothesis is tested by descrambling the data and using error detection to ascertain whether errors are present. Once the correct scrambling sequence has been identified the S additional data bits and block of D data bits can be determined. The S additional data bits may be transferred with no increase in the polar coding rate. The S additional data bits may represent uplink or downlink control such as ACK/NACK, RNTI, cell ID or puncturing information in eMBB multiplexing.

Title: Boiler control system and method
Inventor: DEREK COPE
IPC: G05D23/19
Filed: 2018-12-11
Abstract: The boiler control system controls a heating device in a boiler 1, such as a burner 2. A delayed cycle controller 20 activates and deactivates the burner based on an output of a drive signal detection means 94 and on an upper threshold temperature and a lower threshold temperature. An interrupt switch, ideally a relay 28, is arranged to selectively prevent an enable signal 26 from reaching the device/burner. Preferably the enable signal is from a building management system (BMS) 24 and is barred from reaching the burner by the relay until a boiler temperature measured by a temperature sensor 22 falls to a lower target temperature set by the controller 20 that is less than the lower threshold temperature. The lower target allows residual heat in the boiler to be used before the burner is fired, increasing boiler efficiency. The system may perform a calibration operation whereby the controller monitors normal boiler operation to determine the internal upper and lower temperature thresholds by taking temperature measurements when the drive signal detection means senses starting and stopping of the burner. A method is also claimed.
