Abstract: An electronic trigger assembly for a firearm includes a firearm control mechanism, a safety actuator and a firing actuator. The firing control mechanism is configured to operate in a safe mode or a shot mode. The safety actuator is configured to actuate a safety rod linearly in a first direction to switch the firing control mechanism between the safe mode and the shot mode. The firing actuator is configured to actuate a firing plunger linearly in a second direction to actuate the firing control mechanism in the shot mode.

Abstract: A device includes: a gyroscope adapted to be mounted to a goniometer, wherein a sensitivity axis of the gyroscope is substantially perpendicular to a rotation axis of the goniometer, wherein the goniometer is adapted to provide at least a first goniometer azimuth reading (A1) at a first azimuthal direction and a second goniometer azimuth reading (A2) at a second azimuthal direction, wherein the gyroscope is adapted to provide at least a first gyroscope angular rate reading (?1) at the first azimuthal direction and a second gyroscope angular rate reading (?2) at the second azimuthal direction, wherein the device enables measurement of a tilt angle.

Abstract: A method for calibrating the attitude of a compass in relation to the platform on which the compass is installed. The compass includes an attitude determining device and an optical sighting device and the compass is integrally mounted on a platform. The method includes the steps of determining the angle between the optical sighting device and the attitude determining device, determining the attitude between the optical sighting device and the platform, and determining the attitude between the attitude determining device and the platform.
