Title: A surface cleaning apparatus
Inventor: RICHARD WATERS
IPC: A47L9/16
Filed: 2017-12-05
Abstract: A surface cleaning apparatus comprises a housing supporting a suction source, a cyclonic separator device 18 having an elongate axis A which lies in a plane (Q1, fig 8), a user graspable handle (20, 21 fig 4) having an elongate axis (C, fig 5) and a passage member (19, fig 5) for transporting dirt-laden air to the dirt separation having an elongate axis (B, fig 3). The elongate axis (B, fig 3) of the passage member and the elongate axis (C, fig 5) of the user graspable handle lie in a plane (P1, fig 3), and the elongate axis A of the device intersects the plane (P1, fig 3). The cyclonic separator device 18 includes a first separating chamber 18c fluidly connected to the passage member for separating relatively coarse dust or debris from any dirt laden air received from the passage member, an inlet through which dirt-laden air is drawn into the first dirt separating chamber, a first dirt collection chamber 18b for receiving dirt separated by the first separating chamber, a shroud 100, an outlet through which cleaner air exits the first separating chamber and a baffle 62 positioned in the first dirt collection chamber which lies in a plane (R1, fig 8). In side view the plane (Q1, fig 8) is perpendicular to the vertical and the baffle 62 is positioned above the plane (Q1, fig 8) such that, in normal use, dirt collected in the first dirt collection chamber 18b reaches the plane (Q1, fig 8) before the dirt reaches the baffle 62. Various other arrangements are also disclosed.

Title: Electronic receipt system and method
Inventor: ANDREW PETER LYON CARROLL
IPC: G07G1/00
Filed: 2013-07-19
Abstract: A Point of Sale (POS) system 101 sends a transaction record in an unknown format to an output e.g. a printer 102 or serial port and a data reader redirects the data to obtain a copy of the transaction record. When available customer identity information is collected and the transaction record is sent to a parser to be converted into an electronic receipt of known format to be correlated with the customer identity information and stored electronically for viewing, e.g. using a web browser 307-308 or mobile device app 306. A paper receipt may also be printed. The parser may be unique to the retailer or POS terminal and the system may include a parser builder arranged to initially generate the parser (Figures 10a-c), identify regions in the transaction record data corresponding to states in a state machine and/or identify similar previous transaction records in a library. The parser may check electronic receipt data for correctness, the builder refining the parser if errors are detected. Thus electronic receipts to be generated using existing POS equipment without the co-operation of the POS supplier in providing information about the format or software used.

Title: Failsafe industrial actuator
Inventor: Jan Welzien
IPC: F16H61/12
Filed: 2018-01-11
Abstract: An industrial actuator 10 comprising a first and second parallel drive train 12, 14 having respective first and second coaxial outputs 13, 15. A clutch assembly 17, 18 selectively connects drive from an input 16 to move one of the drive trains. A latching mechanism 20 selectively maintains an energy store 19 coupled to the first output in an energised state. A rotary ratchet coupling between the first and second output is configured such that the clutch assembly connects the drive to the first drive train and drives the first output in a forward direction energising the energy store; the clutch assembly connects the drive to the second drive train to drive the second output, such that the output may move a drive shaft coupled to the second output from a first, failsafe, position to a second position. Releasing the latching mechanism releases the energy from the energy store, causing the first output to be driven in a reverse direction, and the ratchet coupling provides a rotary engagement between the first and second output in the reverse direction such that the drive shaft is urged towards a failsafe position.

Title: Execution unit in Processor
Inventor: Jonathan Mangnall
IPC: G06F7/556
Filed: 2019-03-11
Abstract: Execution unit 300 receives an instruction with a floating-point operand and op-code to generate an exponential of the operand. Multiplier 410 multiplies the operand and a fixed multiplicand, logged to the base 2 (e), log2e, provided by a control circuit which also extracts integer and fractional parts from the multiplier result. An exponent Ey of the exponential result is formed by the integer part stored in an exponent register. The mantissa of the exponential result, My, is obtained by multiplying (320a) an estimated fractional component 2f1’ and a value 2f0’ accessed from look up table (LUT) 415, wherein the LUT is accessible by a bit sequence representing a fractional part f. A preparatory circuit splits the mantissa into sub‑components by extracting at least two bit-sequences from the mantissa of the operand, using one bit sequence f1’ to generate the estimated fractional component, and the other bit-sequence f0’ to access the value from the lookup table. Pre‑multiplying the operand with the fixed multiplicand allows re-writing the exponential function as the split product of two powers of two. Uses comprise neural networks.

Title: A water desalination process
Inventor: TOM MARREN
IPC: C02F103/08
Filed: 2019-11-15
Abstract: A water desalination process comprises the steps of submerging, in saltwater, a container 3 having a charging inlet 5 covered by a reverse osmosis (RO) membrane 7 to a filling depth where the water pressure external the container adjacent the RO membrane exceeds the osmotic pressure of the RO membrane, preferably wherein the filling depth is at least 270m; filling the container with permeate water and harvesting the permeate water from the interior of the container. The permeate harvesting may involve raising the container from the filling depth such that at least part of the container is above the saltwater surface. In this instance, the permeate can be harvested sequentially from a series of discharge outlets which are spaced apart along the height of the container. Alternatively, the permeate harvesting may involve pumping the water from the submerged container. The submerging can comprise driving the container downwards along a guide assembly 11 comprising a pulley 15, a cable 13 led around the pulley, and a counterweight. The counterweight can be a second container, wherein the pair of containers may be operated in a funicular fashion. The energy requirement for passing the saltwater through the RO membrane is significantly reduced.

Title: Processing mass spectral data
Inventor: JEFFERY MARK BROWN
IPC: H01J49/40
Filed: 2016-10-14
Abstract: A method of mass spectrometry comprises transforming mass spectral data (e.g. using Fourier transform or wavelet transform) to produce frequency domain mass spectral data. The frequency-domain mass spectral data is modified to produce modified frequency-domain mass spectral data by attenuating or removing one or more frequency ranges that relate to noise associated with peaks of interest in the mass spectral data. The modified frequency domain mass spectral data is then transformed to produce modified mass spectral data, which may have a lower level of background noise, peak skirts or baseline artefacts. The method may be applied to time-of-flight mass spectral data. The frequency ranges to attenuate or remove is selected on the basis of the average number of collisions experienced by ions or the collision cross section of ions corresponding to the peaks of interest. Step, window, apodisation or tapering functions having maximum and/or minimum frequency may be used.

Title: Integrated interactive image segmentation
Inventor: BRIAN LYNN PRICE
IPC: G06T7/194
Filed: 2021-01-27
Abstract: Methods and systems are provided for optimal segmentation of an image based on multiple segmentations. In particular, multiple segmentation methods can be combined by taking into account previous segmentations. For instance, an optimal segmentation can be generated by iteratively integrating a previous segmentation (e.g., using an image segmentation method) with a current segmentation (e.g., using the same or different image segmentation method). To allow for optimal segmentation of an image based on multiple segmentations, one or more neural networks can be used. For instance, a convolutional RNN can be used to maintain information related to one or more previous segmentations when transitioning from one segmentation method to the next. The convolutional RNN can combine the previous segmentation(s) with the current segmentation without requiring any information about the image segmentation method(s) used to generate the segmentations.
