Abstract: Systems and methods for a radio communications device supporting LTE cellular communications. A device includes a data interface configured to exchange modem control commands and audio data with an LTE cellular modem and a telephone interface configured to provide a two-wire analog telephone interface for connection to a telephone device. A controller control signals provided via the telephone interface to manage voice call operations with the telephone device; exchange digital voice data corresponding to voice signals exchanged with the telephone device via the telephone interface; exchange control information via the data interface to establish and manage a voice over LTE cellular call; and exchange the digital voice data via the voice over LTE cellular call via the LTE cellular modem.

Abstract: An weapon sight system includes a weapon sight having body with an optical element that is configured to superimpose a reticle that is visible through the optical element. The weapon sight includes a controller in electronic communication with and configured to control a light source. The light source may include an LED for generating a reticle image on the optical element at a plurality of different brightness conditions. The light source may include an array of LEDs for generating multiple different reticle images on the optical element. The weapon sight includes a Hall effect sensor in electronic communication with the controller to adjust user-selectable settings including reticle brightness or reticle image. The weapon sight system includes a magnetic input device for providing an input to the Hall effect sensor of the weapon sight.

Abstract: A system for controlling a vehicle powertrain is disclosed. The system includes a powertrain circuit for receiving a plurality of powertrain operating signals, processing the operating signals, and outputting a plurality of powertrain control signals for controlling the vehicle powertrain, and an air-intake manifold fixable to an engine of the vehicle powertrain and adapted to receive the powertrain control circuit. The present invention provides a self-contained vehicle powertrain that is testable before installation into a motor vehicle.
