Title: A garment air supply device
Inventor: JEFFREY PETER CROCKER
IPC: A62B17/00
Filed: 2021-02-23
Abstract: A wearable air supply apparatus 99 comprising an air supply (into 88) including a compressed air line anchored on a belt 1, 12, comprising a splitter 11 to direct the air down two lines, one of those lines being a conduit 3 which terminates in an air distribution component 4 (see also figure 2), the air distribution component extending from the exterior into the interior of the garment; such that a portion of the air supply is directed into the garment to provide cooling for a wearer. The apparatus may comprise a second splitter (2, figure 2) to direct some air towards a mask. The apparatus might form part of a set of overalls. The other side of the splitter 11 might be connected to a spray applicator downstream, like a paint applicator, such that a single air supply can both cool an operator in a protective garment and allow the use of air-powered tools.

Title: Actuator fabrication
Inventor: OLIVER HART
IPC: G03B3/10
Filed: 2021-04-08
Abstract: A method of forming an actuator assembly 2, 30 includes crimping a first shape-memory alloy wire 12 to a first patterned sheet 14 which includes a frame 15, a features 16, 19 supporting or defining crimp heads 17, 20 and connected to the frame 15 by connecting members 18, 21. The first shape-memory alloy wire 12 is crimped between the crimp heads 17, 20. A second patterned sheet 22 similarly includes crimp heads which support a second SMA wire 13. The first and second patterned sheets 14, 22 and first and second parts 3, 4 are joined to form a first assembly, in which the SMA wires are attached between the first and second parts. The first and second parts are coupled by a bearing assembly configured to couple a rotation of the second part 4 relative to the first part 3 about a primary axis to a translation of the second part relative to the first part along the primary axis, thereby providing helical movement. After assembly, the first and second connecting members 18, 21 are severed to detach the frames from the crimp heads.

Title: A business method for a financial instruments lottery implemented in software or hardware
Inventor: Heiko Ackermann
IPC: G06Q40/06
Filed: 2021-12-16
Abstract: A business method for processing financial transactions by a retail broker comprising: the retail customer getting a list, set or graphical representation of available financial instruments, selecting the financial instruments or accepting the pre-selected financial instruments, and selecting the amount of money they want to spend. The retail broker then processes the selected financial instruments sequentially or parallelly so that they are bought and sold after a specified timeframe or based on market events. The processing is finished when all selected instruments are processed or until no money is left. The invention also envisages at least one server including a connection to a market maker, automated trading system, exchange or financial intermediate to buy or sell financial instruments, providing a web service, an API, or Web GUI for interacting with customers through a user interface to obtain a ticket in electronic form, and processing the elements of the electronic ticket.

Title: User voice activity detection methods, devices, assemblies, and components
Inventor: Jiajin An
IPC: H04R3/00
Filed: 2018-02-13
Abstract: A user 101 wears a headset 110 with microphones FFA, FFB, FBA, FBB near the user’s ears 102A, 102B and a microphone 120 near the user’s vocal region 101V. The microphones near the user’s ears may be used for active noise cancellation (ANC). Two of the microphones near the user’s ears are used to detect if the user is speaking. Similarity between the phase and magnitude of sound detected by a microphone at a user’s first ear and another microphone at a user’s other ear may be used to identify the sound as the user’s voice. Alternatively, differences in the magnitude or arrival time of the sound detected at two microphones at the same ear may be used to identify the sound as the user’s voice. The microphones at the same ear may have different acoustic coupling to the user’s vocal region. They may be a feedforward FFA, FFB and a feedback FBA, FBB microphone. On detecting that the user is not speaking the microphone near the user’s mouth may be muted or attenuated.

Patent GB-2614757-A (GB)
Title: A system for harnessing a pressure fluctuation of a liquid
Inventor: PAUL ANDREW BATEMAN
IPC: F03B13/00
Filed: 2022-01-18
Abstract: A system for harnessing water pressure fluctuation comprises an accumulator 2 with a water space 3 connected e.g. to a potable water system, and a pneumatic space 4 containing air or other gas, separated by a flexible diaphragm 5. The air is connected to a pneumatic actuator which drives an electrical generator. Pressure fluctuations in the liquid pipework therefore drive the pneumatic actuator and generate electricity. The pneumatic actuator may be a piston in a cylinder, driving the generator via a crankshaft. The pressure fluctuations may result from water hammer, e.g. when a tap or valve is opened or closed, and water hammer may be produced deliberately to increase power output.
Patent GB-2605281-A (GB)
Title: Modulation of packetized audio signals
Inventor: Gaurav Bhaya
IPC: G10L19/018
Filed: 2017-08-31
Abstract: A system for modulating an output signal receives a first voice input from eg. a microphone, parses it to identify a request and a trigger keyword corresponding to the request, selects a first content item associated with a third-party provider device and determines its context. It then selects a first audio modulation (eg. a frequency/amplitude shift, overlay or audio watermark), different to a default modulation (eg. none), to apply to an output signal of data packets corresponding to the first content item which are transmitted to eg. a smart speaker. Detecting a different network activity may then terminate the communication session.
