Title: Transmission techniques in a cellular network
Inventor: GUANG LIU
IPC: H04W72/12
Filed: 2018-07-11
Abstract: A base station schedules transmission of data to a UE and transmits a downlink control information (DCI) message indicating the scheduled transmission to the UE. The scheduled data is transmitted and if an acknowledgement message from the UE indicates the data was incorrectly received, retransmission of the data is scheduled. A further DCI message is transmitted indicating the scheduled re-transmission. The further DCI message has a reduced size compared to the original DCI message. The further DCI message may omit parameters which have been sent in a pre-configuration message to the UE. The further DCI message may specify changes to the original DCI message, define parameters from a reduced set of possible options or may not include a CRC field. The further DCI message may provide a more robust transmission format than that of the original DCI message.

Title: Apparatus and method of mapping a virtual environment
Inventor: ANDREW SWANN
IPC: G06T19/00
Filed: 2018-07-13
Abstract: Method of mapping a virtual environment, comprising: obtaining a sequence of video images output by a video game; obtaining a corresponding sequence of virtual camera positions at which the video images were created; obtaining a corresponding sequence of depth buffer values; for each of a plurality of video images and corresponding depth buffer values: obtaining mapping points, corresponding to a distribution of points sampled over the area of a respective image and their associated depth values; wherein respective mapping points are obtained by projecting coordinates derived from the sample points and associated depth values back into a world coordinate system of the video game; thus obtaining a point cloud data set of mapping points from the video image sequence. Sample points may be pixels, subsampled pixels, interpolated super-sampled pixels, Gaussian or random sample distribution. Projecting may involve transforming coordinates through inverse perspective projection matrix and inverse camera matrix or forming a frustrum between two planes and interpolating sample point positions based on depth value. Mapping points may be snapped to a volumetric grid. Meshes may be generated from point clouds using screened Poisson surface reconstruction or ball-pivot surface reconstruction. Colour data may be associated with mapping points.

Title: A personalized real-time location-based decision-making aid method and a personal assistant device for applying the method
Inventor: ADRIAN HOMUTESCU
IPC: G06Q10/10
Filed: 2018-11-27
Abstract: A personal assistant to aid decision making identifies a user and receives two categories of real time data: personal data including the user’s perceived needs, preferences and objectives; and secondary data from multiple other sources. Using both data sets, an individual user profile is built and continuously updated by ranking the data against metrics. Using the rankings, a suggested activity to aid the user meet their objectives is determined. The recommended activity is displayed alongside the impact and risks to the user’s objectives if they carry out the activity. The user indicates whether they intend to carry out the activity or not, and the user’s profile is updated accordingly. The user may specify a physical location with which suggested activities should be associated. The suggested activity may be broken down into intermediate steps to achieve an objective. The data may include vehicle parameters if the personal assistant is inside a vehicle. Also claimed is a personal assistant device which includes a localisation module to determine the device’s position and compare this with activity locations to advise on alternative suggested activities but does not receive an indication of whether the user will carry out each recommended activity.

Title: Landing gear assembly
Inventor: SEAN KERR
IPC: B64C25/10
Filed: 2019-06-28
Abstract: A landing gear assembly 1 comprising a main strut 8 moveable between an extended position and a retracted position; an actuator 12 connected to the main strut and configured to move the main strut from the extended position to the retracted position; and an accumulator 24. The accumulator may comprise a spring or a pneumatic or hydraulic accumulator, for example an air spring or spring type hydraulic accumulator and be moveable between a lower stress configuration and a higher stress configuration in which the store of potential energy in the accumulator is increased relative to the lower stress configuration.
