摘要： A proportional control circuit for the direction and precise speed control of D.C. electric motors such as those used to drive camera tilt/pan mountings. The circuit applies current to D.C. motors in a push/pull proportional scheme whereby slewing speed is smoothly and precisely controlled and electromotive force provides motor braking. A single current source powers the motors through an "H" bridge switching amplifier arrangement responsive to the balance between two voltage dividers, one of which includes a controlling potentiometer that regulates both direction and speed.

摘要： A control system for a surveillance vehicle (V) is disclosed. The vehicle includes a rapid deployment and retraction mechanism (A') and a jack system (B') for continuously maintaining a detection device (28) a top a mast (12) within a prescribed vertical condition when extended. The control system includes a jack leveling logic circuit (C), a jack pressure control circuit (D), a ram control circuit (E), and a mast control circuit (F). Ram control circuit (E) controls a ram (52, 54, 56) which deploys and retracts mast (12). Jack pressure control circuit (D) senses the pressure on jacks (142a, 142b, 142d) at the four corners of the vehicle. Jack leveling logic circuit (C) receives pressure signals representing the pressure on the jacks and controls extension and retraction of the jacks in pairs at diagonal corners to maintain the vehicle within prescribed leveling conditions and to prevent the over extension or over adjustment under certain unleveling conditions. Mast control circuit (F) receives a signal representing the level condition of the vehicle so that the mast is extended and retracted only under prescribed leveling conditions.

摘要： A rapid deployment surveillance vehicle is disclosed for detecting illegal immigration across national borders and the like. An off-the-road vehicle (V) is equipped with a rapid mast erection/retraction assembly (A) which includes a carriage mechanism (24) which carries a telescoping mast (12). A track mechanism (20) slidably carries the carriage mechanism (24) by means of a fixed support (22) and pivoting support arms (26). Ram air cylinders (52, 54, 56) move the carriage mechanism in translational and rotational movement as guided on the track mechanism in a manner that the mast (12) is moved from a stowed horizontal position to an erect vertical position. During erection of mast (12), a longitudinal roof opening (10) is opened by means of a main door (14) and displacement door (16) in an automatic manner. Once erect, a leveling system (B) checks to ensure that the vehicle is within one degree of level. Both level sensors (182) and pressure sensors (148) ensure that the vehicle is level and that all four jack legs (150 ) are firmly engaged against the ground prior to extension of mast (12). Once the vehicle is within the prescribed level conditions, mast (12) is pneumatically extended to a height of thirty feet whereupon a detection device (28) which may be in the form of an infrared camera is ready for surveillance. Camera (28) is mounted on a pan/tilt device (30) which rotates it in a horizontal plane and tilts it in a vertical plane for increased surveillance. Wiht the mast within one degree of true vertical, a stable platform is provided for camera (28) so that a nondistorted image appears on the display of a monitor (27) remote from the camera.
