Abstract: A beam layout is optimised for a given traffic distribution and network state by determining optimum beam centre positions and generating a beam layout so as to meet system requirements and minimise the distances of locations within a coverage area from the optimum beam centre positions. Adjacent beams in low traffic areas may be merged.

Abstract: Embodiments described herein are directed to posture assistance devices that may include a motor coupled to a frame, where the frame attaches to a wheelchair. In some cases, the devices include a shaft coupled to the motor, where the motor is configured to rotate the shaft. The devices can also include an extension arm attached to the frame, where the extension arm includes a redirection surface. The extension arm can be selectively adjustable to change the distance between the redirection surface and the shaft. The devices can also include a connection line coupled to the shaft and configured to engage with the redirection surface, such that rotation of the shaft changes a length a fed-out portion of the connection line. The connection line can also include an attachment mechanism that couples the connection line to a user.

Abstract: The disclosed computer-implemented method may include identifying and notifying requestors that may be candidates for a particular autonomous vehicle in order to find those candidates that may be willing or able to relax their travel constraints to match the autonomous vehicle. A request flow may involve surfacing the potential option of matching to an autonomous vehicle before setting a specific destination. For example, the request flow may involve determining that an autonomous vehicle is sufficiently near an in-session potential requestor. Before the potential requestor enters a specific destination, the request flow may present the possibility of the potential requestor being matched with the autonomous vehicle. In some examples, the request flow may then provide available drop-off locations that are compatible with the autonomous vehicle for selection by the potential requestor. Various other methods, systems, and computer-readable media are also disclosed.

Abstract: Computer systems and methods are disclosed to implement a role manager that automatically analyzes code accessing various resources to generate a role with the necessary resource permissions to execute the code. In embodiments, the role manager may be implemented as part of a workflow orchestration or resource provisioning system that employs code requiring access to different types of resources. In embodiments, the role manager may analyze a code segment to identify the different resources accessed by the code segment and the permissions needed for each access, and generate a role that has the needed permissions. In embodiments, the role manager may automatically manage these roles based on changes to associated code segments. Advantageously, the disclosed role manager removes the need to manually create roles need by code segments ahead of time, and creates roles with minimal privileges required for the code, thereby simplifying achievement of system security.

Abstract: A High Bandwidth Individual Channel Control via Optical Reference Interferometry (HICCORI) system actively controls the phase and/or polarization of the optical emission of each element in a tiled optical array. It can also actively align any high-frequency broadening waveform applied to the array beams for spectral broadening or data transmission. By maintaining consistent polarization and manipulating the phase relationships of the beams emitted by the array elements, the HICCORI system can manipulate the spatial pattern of constructive and destructive interference formed as the individual emissions coherently combine. Active feedback control allows the desired phase, polarization, and/or spectral broadening alignment to be maintained in the presence of external disturbances.
