Abstract: A method for optimizing group communication services, the method including determining a current location and an assigned home server for one or more devices associated with each of a plurality of group members, determining whether the one or more devices of the plurality of group members has moved to a visiting location, wherein the visiting location is a location outside of locations associated with the assigned home server based on the current location and assigned home server for the one or more devices, and assigning a group control application server associated with the visiting location to the to the one or more devices to serve as the assigned home server.

Abstract: A method for optimizing group communication services, the method comprising instantiating an adaptive homing tool as a virtual network function, the adaptive homing tool communicating with a centralized database in a multiple region telecommunications network; storing a user identification for plural group members in the database; when a service request is made by at least one group member that has moved outside of connectivity with a group home server, receiving group member location data for the plural group members in real time; assigning a group control application server to at least one group member when a group member initiates a service request; wherein the common service tool assigns the group application control server based on at least one of the priority data, group member location data, least network resources used, best path performance, shortest path performance, and quality of service.

Abstract: A machine gun unit comprises a machine gun mounted to a support by a mounting permitting pivoting movement of the machine gun relative to the support in azimuth and/or elevation. Angle encoders provide position signals representing angular displacement of the machine gun relative to the support. An aiming system comprises a sensor, for example a CCD sensor, which provides a video signal representing a field of view for the aiming system, a display device for displaying the field of view, a manual input interface, a graphics artifact generator, and a digital signal processor (DSP). The DSP monitors the outputs of the angle encoders and controls the graphics artifact generator to combine the output of the graphics artifact generator with the output of the CCD sensor for display by the display device. Various graphics artifacts can be provided. Masks may be provided for delimiting field of fire. A cursor may be repositioned to reflect superelevation requirements.

Abstract: In apparatus, such as a weapon sight, the speed of an object moving relative to a scene is determined by processing a plurality of successive frames of data, each obtained by scanning the scene, and detecting motion of the object relative to the background/foreground features of the scene. Each frame is compared with a reference comprising a different one of the frames and corresponding background features registered. Once the frames are registered, light intensity values of corresponding elements of the frames are subtracted. The registered background features, being stationary, cancel leaving the object features. Displacement of the object features over a predetermined number of frames is used to calculate the crossing speed of the object relative to the background features.
