摘要： An automated indoor pistol range target carrier has an overhead power rail along which a target-supporting, -lighting and -rotating carriage travels toward and away from the firing line. The carriage supports, rotates, repositions and lights the target and is controlled by and feeds back information as to the target's position to a central controller. Portions of the power rail are electrically insulated one from the other and function as bus bars to carry d.c. current used to operate motors and circuits in the trolley without using electrical cables. Electrical pickups in the form of wheeled trolleys wipe the bus bars to supply power to motors and lights to operate the various target carrier systems. All system components are located within the carriage which may easily be removed from the rail for service without requiring the disconnection of any power cords or cables.

摘要： A sector scanning search unit which supports a transducer for oscillation about a virtual pivot axis extending medially across the face of the transducer. The scanner unit is an elongate hand held unit in which the transducer is supported near one end of a chassis. The transducer's face is oriented transversely of a longitudinal axis of the chassis and on a side of the transducer opposite its supporting structure. The sector scanner is also provided with a mechanism for readily adjusting the magnitude of the sector being scanned, even while such scanning is taking place.
