Title: Passive combined indoor positioning system and method based on intelligent terminal sensor
Inventor: ZENGKE LI
IPC: G01C21/00
Filed: 2023-01-05
Abstract: An indoor positioning system comprises collecting geomagnetic data, angular velocity data, and acceleration data pertaining to a target user at a current time point. A dead reckoning module detects a user gait based on acceleration. A step length of the user is estimated based on a step length regression model. The step length regression model is constructed based on a step frequency of the target user and an acceleration inertia integration result. A geomagnetic matching module determines a candidate fingerprint database based on the current dead reckoning result. A geomagnetic matching weight is determined for each particle in the candidate fingerprint database. A single-point matching module is configured to determine coordinates and a weight of each particle in the candidate fingerprint database based on the geomagnetic data. A sequence matching module matches geomagnetic data of a current sequence segment data of each fingerprint segment in the geomagnetic fingerprint database giving coordinates and a weight of each fingerprint segment. A positioning module determines a final positioning result of the current particle based on the coordinates and the weight of each particle in the candidate fingerprint database. An error correction module corrects the step length regression model.

Title: Methods and systems and apparatus to support reduced energy and water usage
Inventor: Peter Konowalczyk
IPC: F24H15/156
Filed: 2021-07-02
Abstract: A processor 150 and memory 151 are used to control a heat pump in an installation 100. The installation includes an in-building hot water supply system 110, the heat pump 120, which is arranged to heat water in the hot water supply system, and an energy storage arrangement 140 containing a mass of energy storage medium, possibly a phase change material (PCM). The processor is configured to provide a signal to the heat pump based on the opening of an outlet 130 of the hot water supply system. The processor receives information on the status of the energy storage arrangement, such as a status of the PCM that is in turn indicative of the thermal energy available from the energy storage arrangement. The memory is operatively coupled to the processor and stores instructions that are used by the processor control the heat pump. When the processor senses opening of the outlet, the processor determines whether to provide a start signal to the heat pump based on a sensed hot water flow rate, the status of the energy storage arrangement, and the status of the heat pump.

Title: Computer-implemented method of generating PWM control signals, and corresponding computer program, computer-readable storage medium and apparatus
Inventor: MARK EASTON
IPC: H04N23/66
Filed: 2021-12-14
Abstract: A computer-implemented method driving an actuator component that drives movement of a movable part relative to a support structure, an image sensor fixed relative to the movable part or the support structure. The image sensor carries out CDS so as to read, offset in time by a sampling period, a reference signal and a light-sensing signal, and outputs a sync signal prior to CDS. The method comprises receiving the sync signal; generating PWM control signals at a PWM frequency substantially equal to an integer multiple of the reciprocal of the sampling period; during a sensing interval, suspending generating PWM control signals to drive the actuator component; and scheduling the sensing interval to start a time delay after receiving the sync signal, such that the sensing interval overlaps with both or neither of a duration of reading the reference signal and a substantially equal duration of reading the light-sensing signal by the image sensor.

Abstract: The present invention relates to stable aqueous suspension concentrates or aqueous flowable compositions of the low-melting dinitroaniline pesticide, pendimethalin, alone or in combination with secondary pesticide(s) melting at temperatures greater than 70<o>C or pesticides which are water soluble. Preferred compositions of the invention comprise on a weight to volume basis, about 5.0% to 50.0% pendimethalin; about 0% to 50.0% of one or more secondary pesticide(s); about 3.0% to 30.0% of coformulants, such as surfactants, dispersing agents, wetting agents, antifreezing agents, antifoaming agents, thickening agents, gums, preservatives and 20.0% to 92.0% water. The stable compositions of the invention are readily prepared by forming an emulsion of molten pendimethalin in water containing the coformulants, surfactants, dispersing and/or wetting agents, antifoaming agents and suspending agents. This emulsion has an average droplet size in a range of less than 2 microns to about 10 microns, preferably 2 microns to 6 microns. This is then cooled and optionally milled to obtain an average particles size of suspended particles of less than 20 microns, preferably less than 5 microns.

Abstract: In a method and apparatus for the electronic measurement of the electricity used by a load, a rectified voltage signal proportional to the load voltage is generated, and a frequency modulated pulse train is generated in response to this rectified voltage signal, with the frequency of the pulses being proportional to the instantaneous amplitude of the rectified voltage. A load current signal is generated that is proportional to the load current and is gated during each pulse of the frequency modulated pulse train to generate a signal representing the product of the instantaneous load voltage and the instantaneous load current. This signal may be integrated over time to generate a signal representing the amount of electric energy used by the load.

Abstract: The invention is a method of forming a solder bump (17) on an under bump metallurgy (13) in which a contact pad (11) on a substrate material is partially covered by a passivation layer (12) upon the substrate material which is non-wettable by solder and in which the under bump metallurgy (13) covers the portions of the contact pad (11) which are not covered by the passivation layer (12) and in which the under bump metallurgy overlaps from the contact pad to cover portions of the passivation layer. The method comprises depositing a layer of solder soluble metal upon the under bump metallurgy so as to cover the under bump metallurgy with the solder soluble metal; coating the deposit of solder soluble metal with a layer of solidified solder while substantially avoiding complete dissolution of the solder soluble metal in the solder; and heating the solder until the layer of solder melts and the deposit of solder soluble metals substantially completely dissolves in the melted solder and the surface tension of the melted solder draws the solder and dissolved solder soluble metal away from the non-wettable passivation layer (12) and into a spheroid solder bump (17).
