Title: Method, system and computer program for comparing images
Inventor: RUSSELL KING
IPC: H04W12/06
Filed: 2014-03-28
Abstract: A method of determining whether a user of a mobile device corresponds to a user that has been previously authenticated via an identity document (110) that has an integrated circuit (IC) component storing a digital image of said user, e.g of a face. The method comprises: using the mobile device 300 to cause a chip reader to access the IC component, and to retrieve the digital image of the previously-authenticated user; also using the mobile device to cause a camera to capture a first image of a user of the mobile device. The method further comprises comparing, by the processing system of the mobile device, the retrieved digital image and first image, to determine whether they represent the same user. If they do the mobile device forms an association between the previously-authenticated user and the mobile device, so that the mobile device is verified as being owned by said authenticated user. The chip reader and camera could be connected to or integral with the mobile device.

Title: Vehicle with event recording
Inventor: MICHAEL EDWARD LOFTUS
IPC: G08B13/196
Filed: 2017-06-23
Abstract: Sensors on a vehicle make a primary detection 704. For example, a break-in or hit-and-run may be detected by perpetually running accelerometers, ultrasonic sensors, microphones or sensors for detecting window breakage or door opening. Objects 708 within a focus area 706 are listed and marked as partially or fully identified 710. For example, optical character recognition software may analyse an image including a license plate and mark it as fully identified if each character is resolved. Connected vehicles are selected based on estimated velocities 714 of the partially identified objects and instructed (e.g. by hand-off 716) to record those objects and transmit the recordings to an address. The list may be an active tracking list and objects may be removed from it upon being fully identified. The focus area may be calculated based on a side of the vehicle identified from the primary detection and an elapsed time and objects outside the focus area may be excluded from the tracking list.

Title: Application certificate
Inventor: CHRIS LORESKAR
IPC: H04L29/06
Filed: 2017-09-01
Abstract: A specified application installed on an electronic device is enrolled into a chain of trust provided by a public key infrastructure (PKI). In the chain-OF-trust, child certificates are validated by attestors associated with parent certificates. Enrolling includes generating an application certificate 20-A for verifying that the application is installed on the electronic device, where application certificate 20-A is a descendant of device certificate 20‑D. The application certificate, e.g. X.509, is signed with a private key 24 to provide identity of the electronic device. The application is installed after successful PKI verification of the electronic device. An enrolment flag in installation commands specifies whether the application is to be enrolled, the commands having an embedded certificate signing request. Enrolling is under control of code executed in a trusted environment. The application certificate specifies a version identifier and is generated newly when updating to a new version. Uses includes Internet-OF-Things (IoT) devices.

Title: One trip tubular cutting and milling down tube and associated collars
Inventor: George N Krieg
IPC: E21B29/00
Filed: 2016-07-05
Abstract: In a plug an abandon environment with casing and a tubular string running through the casing a tool is placed at a desired location for a severing of the inner tubular. A first set of blades is extended from a housing to cut radially until the inner tubular is severed. A second set of blades are then extended for axial milling with a reach limit of the outside wall of the severed tubular at a location between upsets. As the axial milling reaches an upset, the second set of blades is allowed to retract and a third set with a longer reach is extended to axially mill the upset. Thereafter the third set of blades is allowed to retract and the second set is extended to continue axial milling. The second and third sets of blades can be reversed so that initial axial milling can be at the upset rather than between the upsets followed by milling between the upsets with the shorter reach blades.

Title: Network vulnerability detection
Inventor: Jacques Louw
IPC: G06F21/57
Filed: 2019-05-14
Abstract: Monitoring a directory environment of a computer network to detect vulnerabilities by changing a configuration of a directory environment at a first computer on the network 301, then with a domain replication service, replicate the change at a second computer 302. It then extracts information relating to the change from the replication service 303 and uses that information to detect a vulnerability in the director environment 304. It may also generate a representation of the directory environment 305, and may also change the configuration, replicate the change with the replication service, extract information relating to the change, detect the vulnerability, and repeat those steps until the vulnerability has been eliminated 306. The step of extracting the information may be performed at intervals of 1-60 seconds. The vulnerability may be a control path in the directory environment and it may be eliminated when the change closes the control path.

Title: Reading device / sounding stick
Inventor: KATHERINE SUSAN MCKENZIE
IPC: G09B17/02
Filed: 2020-10-26
Abstract: A reading device for helping to learn to read comprises a body 2 which has an elongated through opening forming a reading window 3. The window is sized and shaped to enable at least a part of a single row of reading text to be displayed in the window. A panel 4 is moveably mounted on the body so as to be longitudinally movable relative to the body. It variably overlaps the window from one side in order to restrict the width of the window and thereby obscure some of the text aligned with the window. The panel can slide longitudinally across the window. Only a single moveable panel can be mounted on the body to slide from one side to the other, to completely close the window. The body can include a fixed panel on the opposite side to the moveable panel, with the fixed panel acting as a stop to limit the movement of the moveable panel. Locking means can be provided to lock the moveable panel in position. An arm (13b, fig. 2) can be attached to each panel with movement of the panel being controlled by the arm.

Title: Training a neural network
Inventor: MUHAMMAD ASAD
IPC: G06N3/08
Filed: 2020-12-22
Abstract: A method of training a neural network which combines a set of coefficients with input data values. The method begins by training a test implementation of the neural network. A pruner applies sparsity to the coefficients according to a level of sparsity parameter. The test neural network is then operated on training input data using the coefficients to produce training output data. The sparsity parameter is updated based on the accuracy of the test neural network, and a runtime implementation of the neural network is configured using the updated sparsity parameter. Training the test neural network may be performed iteratively and may include updating the coefficients based on the accuracy of the test neural network. Applying sparsity to coefficients may comprise setting a coefficient or group of coefficients to zero. The sparsity parameter may be updated based on an optimisation technique which balances the level of sparsity against accuracy, such as a cross-entropy loss equation. Applying sparsity may comprise modelling the coefficients using a differentiable function and applying sparsity based on an identified threshold value, such that the sparsity parameter can be updated by modifying the threshold value by backpropagating a gradient vector using the differentiable function.
