Title: Motion converting device
Inventor: NICHOLAI SALOVICH
IPC: F01B9/02
Filed: 2022-03-24
Abstract: Disclosed is a linkage mechanism for converting between motion in different directions or planes, specifically a scotch yoke, where there is a magnetic protrusion 12 or patch on one component 20 and a track 22 with magnetic properties on another component 10 replacing a crank pin, such that relative motion of one component in a first mode gives rise to movement of the second component in a different mode, ie, rotation translates to reciprocating, the magnetic protrusion has a shape that is less than 30% different from the width of the track and that is less than 30% of the length of the track. The protrusion may have at least two magnetic poles facing the track, each pole may interact with a different portion of the track. The track may be a permanent magnet. The protrusion may include electromagnets. The device may be used to transfer motion across a hermetic seal.

Title: Apparatus, methods and computer programs for noise suppression
Inventor: Paschalis TSIAFLAKIS
IPC: G10L21/0208
Filed: 2022-04-06
Abstract: Speech signals captured by (eg. phone or earbud) microphones are noise-suppressed while minimising speech distortion by a Deep Neural Network (DNN) machine learning program 205 which receives inputs 203 and obtains two outputs 207 for each frequency band along with accompanying tuning parameters 209 (eg. Acoustic Echo Cancellation measurements, wind or SNR estimates, spatial audio metadata or Voice Activity Detection). Post-processing block 211 then adjusts DNN 205 so that the outputs 207 ultimately yield an adjusted gain coefficient G 213 which a Noise Suppressor 217 uses to supress noise at certain frequencies in microphone inputs S- 215 to output enhanced speech S^ 219. The gain adjustment uses uncertainty measurements of the gain coefficient based on eg. the difference between the two outputs 207.

Title: I/O server services configured to facilitate control in a process control environment by containerized controller services
Inventor: ANTHONY AMARO JR
IPC: H04L67/12
Filed: 2022-06-15
Abstract: Bidirectional communication between field devices and active containerized controller services in a process control environment. An I/O server service within a container 511A receives 540, 542A-B a set of process outputs obtained by field devices 531-533 e.g. measurements from a particular portion of an industrial process at a process plant. The I/O server service generates from the process outputs a plurality of sets of controller inputs 543A-C, each with the same values, and sends each set to a different one of containerised controller services 521A-C. Each controller service executes the same control routine 525A-C to control the same portion of the same industrial plant by generating a set of controller outputs on a plurality of I/O channels 544A-C. The plurality of sets of controller outputs are received by the I/O server service and include an active set of controller outputs. The active set of controller outputs are then transmitted to the field devices to drive a process output and control a particular portion of the industrial process. Prior to transmission it may be verified that the active set of controller outputs have been refreshed within a given time period to confirm that they are not stale.

Abstract: A fingerprint classification and identification method and apparatus including circuitry to analyze a fingerprint image in the form of an N x M matrix of data elements, such data being analyzed in three basic scan windows which are clocked through a matrix array of data elements each containing either intensity data, direction data or both. The first window and its associated circuitry (114,140,200,220) serve to estimate data element directions by analyzing the intensity data in selected direction slits in the window to establish the slit having the ieast summed contrast between data elements spaced apart in the slit by a selected number of data elements. or to establish that there does not clearly exist such a slit. The second window passes through the matrix such that its data elements have already been passed through the circuitry (114,140,200,220) associated with the preliminary direction estimate window and have a preliminary direction estimate of one of the slit directions or "no direction". This second window and its associated circuitry (114,230) enhance the direction estimates made during passage of the first window according to various logic tests which generally seek to identify a slit direction which, along with the directions adjacent to it, are the directions of the predominant number of data elements in the window, or which is the average of the two slit directions which comprise the largest and second largest number of data elements, if they are sufficiently close in direction. The final window examines data elements having enhanced directions and with its associated circuitry (240,210,114), enhances the intensity data of a center data element in the third window, provided the center data element has an enhanced direction other than "no direction", according to an analysis of the center data element and the neighboring slit data elements in the slit with the direction of the enhanced direction of the center data element. The center data element and the neighboring slit data elements are compared with each other for direction data and intensity data and are compared with a mean intensity value for the scan window to derive a correction value for the center data element intensity to arrive at an enhanced intensity value. Separate logic is used to enhance the center data element intensity when it has a direction of "no direction", after which the data is passed into classification and matching circuitry (161).
