A rigid mount, breakaway, quick coupler for fluid interconnection includes a spring-activated mechanical stop therein to prevent flow-checking. The flow check stop is supported in a cross bore in a movable inner body member of the coupler and cooperates with a ramp surface for positioning thereof in aligned or laterally displaced positions from the axially movable, flow-checking valve pin, thereby respectively to prevent or allow valve pin movement.

A proximity sensor for use with a guidance system of a smart bomb including a ranging radar proximity sensor configured for mounting on a smart bomb and a radome connected to the ranging radar proximity sensor. A laser radiation sensor system is attached to the proximity sensor, which is configured and arranged to detect laser radiation reflected from a target which passes through the radome and output the azimuth and elevation angles to the target to the guidance system.

The present invention comprises a device for determining the roll orientation of a body with respect to a local fixed coordinate system or a predetermined reference vector. The device uses a measurement of an external magnetic field, such as the Earth's magnetic field, to determine a roll orientation reference with respect to the field or an uncompensated roll orientation. The uncompensated roll orientation is then adjusted according to a bias angle, such as an angular difference between the external magnetic field and a local fixed coordinate system, to determine the roll orientation of the device with respect to the local fixed coordinate system or a compensated roll angle.

A manually actuated coupler hydraulically connects large diameter high pressure conduits while the conduits are pressurized. One of the conduits is provided with a body 11, a sleeve 12, and a lever 13 for effecting relative movement between the body and the sleeve. The other conduit is provided with a nipple 14. When the nipple and body are initially connected, they cooperatively define a chamber 43 which is hydraulically isolated from both conduits. The lever is then rotated to advance the sleeve toward the nipple and to open poppet valves 33, 34 in the sleeve and nipple to hydraulically connect the conduits through the chamber 43. The sleeve includes a pressure balancing area 48 which is in open fluid pressure communication with the chamber 43 under conditions, so that high fluid pressure from either conduit will pressure balance the sleeve.

A frequency modulated continuous wave (FMCW) radar system having a voltage controlled oscillator (VCO) for transmitting a RF signal and a linearizer for linearizing the VCO. The FMCW receives the transmitted RF signal as an input and outputs a signal to a modulator, which successively sweeps the VCO frequency over a defined range. The receiver mixes a return signal with a sample of the transmitted RF signal to derive an IF signal. An adaptive frequency sample clock drives an analog to digital converter to sample and digitize the IF signal, with the clock being derived from the transmitted RF signal.

A rigid mount coupler in which all movement required for connecting and disconnecting the nipple occurs within the coupler housing. A body member which receives the valved nipple slides within the housing to actuate a locking mechanism to retain the nipple. The body member supports the coupler valve in a spring loaded retainer so that coupler and nipple valves engage and are balanced in valve open positions. A second spring loaded device supports the coupler valve at the open position and resists further opening movement, thereby preventing flow checking at the nipple. Seals between the body member and housing isolate a stepped chamber therebetween in fluid communication with an inner chamber closed by the coupler valve. The volume of the stepped chamber changes upon movement of the body member and is dimensioned to correspond inversely to changes in volume of the inner chamber to prevent a fluid lock condition.
