Abstract: A robot control system determines which of a number of discretizations to use to generate discretized representations of robot swept volumes and to generate discretized representations of the environment in which the robot will operate. Obstacle voxels (or boxes) representing the environment and obstacles therein are streamed into the processor and stored in on-chip environment memory. At runtime, the robot control system may dynamically switch between multiple motion planning graphs stored in off-chip or on-chip memory. The dynamically switching between multiple motion planning graphs at runtime enables the robot to perform motion planning at a relatively low cost as characteristics of the robot itself change. Various aspects of such robot motion planning are implemented in particular systems and methods that facilitate motion planning of the robot for various environments and tasks.

Abstract: A vertical or block chain connector for linking between two closed chain links includes a lower element and an upper element configured to engage with the lower element to form the chain connector in an assembled condition. In use the lower element is disposed vertically below the upper element in the assembled connector. The upper element is a sliding fit with the lower element and the direction of the sliding connection is in a straight line perpendicular to the longitudinal axis of the connector and in a plane which is parallel to the horizontal axis when the connector is vertically oriented in use.

Abstract: Malware detections are received from a plurality of endpoints in one or more enterprise networks. A first and second set of indicators of breach may be identified from the malware detections and, where appropriate, grouped by specific customers. The pattern of progressive deployment of malware directed toward a customer can then be used as a basis for identifying generalized targeting of the customer, or extended staging for a specific attack on the customer such as a ransomware attack.

Abstract: A metal detector apparatus having a balanced coil system, a receiver unit, a drive coil with at least one capacitor forming a series resonant circuit connected to a transmitter unit having a converter, and a drive controller. The metal detector apparatus configuration generates a first square wave signal set to a fixed/selectable operating frequency which is applied to a first drive switch connected on one side to a first voltage potential and on another side to a centre tap of a half-bridge circuit. A second square wave signal set is generated to the fixed/selectable operating frequency and is applied to a second drive switch connected on one side to a second voltage potential and on another side to the centre tap, via which a drive current is supplied to the drive coil.
