Abstract: Calibration technique comprises the production of a calibration signal hag a single sideband of modulation which is locked to an incoming carrier. The sideband may be on either side of the carrier and is phase adjusted to be amplitude modulated, frequency modulated or a combination of the two modulation forms.

Abstract: An electric generator with winding and rotor design so that it powers and multiplexes several sensor inputs during rotor rotation. The rotor may be rotated by any means such as fluid (gas or liquid) or electric motors.

Abstract: A passive radio frequency (rf) sensor is used to track the beacon of a bastic nonguided rocket. Azimuth and elevation data are obtained in conventional radar fashion, but range data is obtained by range tracking the beacon pulse which is timed by a precision crystal controlled clock.

Abstract: An angular rate sensor is conceived which operates by utilizing electrica conducting fluid flowing in a transverse magnetic field. The electric field induced in the flow direction due to rotation will produce a signal that is proportional to angular rate.

Abstract: Sensing elements are located at various required levels in a vacuum dewar. esistance changes are detected external to the container and used to indicate the presence of a liquid at a particular level.

Abstract: The switch is mounted on a cantilever spring which has a contact that can be positioned over and engage individual contacts of a large bank of contacts. A device is mounted on the spring so as to be responsive to forces either electrostatic, magnetic, gas or liquid pressure. These forces selectively select one of the contacts of the bank of contacts.

Abstract: A P-band uniform loop antenna system simulating the small uniform in-phase urrent loop by using a number of smaller radiating elements that are connected in phase so that each current in each element is in phase. Thus, a small uniform loop radiation pattern is simulated, but the loop elements are arranged on a radius that is not small compared to a wavelength, and are located around a cylinder.

Abstract: This device uses an oxide-metal matrix material to enable the integration either constant or pulsed image readout without the use of electron scanning. It takes advantage of a new materials's ability to serve as both a field effect emitter and a matrix channel for the emitted electrons to enable improved resolution.

Abstract: A circuit for determining the acceleration of an object being tracked by a oppler radar wherein a part of the received signal is delayed and then subtracted from the received signal to produce a first signal; a portion of the delayed signal is further delayed and then subtracted from the delayed signal to produce a second signal; and the first and second signals are subtracted to produce a signal representative of the acceleration of the object being tracked by the CW Doppler radar.

Abstract: A corner reflecting antenna is truncated by a reflecting plate. Two rows of ipoles are placed near the throat of the corner reflector (but in front of reflecting plate) and aligned parallel to sides of the antenna. The dipoles are placed at locations that are near multiples of odd quarter-wavelengths from the truncated surfaces. Dipoles lie in the same plane parallel to the truncated surface and equidistant from the sides of the antenna. The rows of the dipoles fed separately by way of two power splitters, a phase shifter and a magic-tee.

Abstract: A system including a pulsed laser for illuminating targets. A detector has shutter synchronized by a radio link from the laser, so that the shutter allows the detector only to be energized when the laser pulses.

Abstract: A light pipe is used between the ground voltage and the extremely high voge end of a system whereby a pulse can be transmitted from the ground potential end to the high voltage end with safety and without distortion.

Abstract: The tracker tracks on a center of contrast on a selected target while trang gates are adjusted automatically to fit the target contrast area's shape and size. The appropriate bright or dark contrast detector is adjusted to allow discrimination of the target contrast from its background, thus allowing a tracking window to encompass the selected contrast area. Orthogonal error signals are provided for servoing a vidicon camera to maintain the viewed field centered on the target.

Abstract: A lifting body missile is controlled by pitch and roll commands wherein the aw autopilot is caused to change in accordance with the roll and estimated angle of attack input information. A command logic is provided to determine the polarity of the command signals to the autopilot.

Abstract: The off axis angle detector of a radar is sampled at discreet intervals by special purpose digital computer. Each sample is directed to one of a plurality of registers in accordance to the angle indication of the sample. Each register being a counter which will give an output when it is in an overflow condition; therefore, each register acts as a threshold device. Upon one register overflowing and giving an output of that indication, the sample process is stopped and the output of the register is sent to a converter to indicate the direction of the jammer. This is done both for the azimuth and elevation angle of the radar receiver.

Abstract: A copper plated styrofoam dielectric planar array antenna having adjacent otted waveguide sections bonded with a silver loaded conducting epoxy. The sections are fabricated by plating a thin film of copper on a preformed styrofoam dielectric material. The slots are machined into the copper plated sections.

Abstract: Alignment of sync pulses is provided by an automatic selection of a proper ath, which is delayed or not delayed, of the sync pulses. The selection is made on the basis of error criteria. A comparator compares the sync pulses and sends an error signal to a sync pulse adjuster which makes the determination of the path to which a sync pulse is directed.

Abstract: Laser light is polarized and sent through a low loss rotator. The amount of otation is modulated by a modulator source. The laser light is then sent through a further polarizer where its intensity will be modulated in accordance with the variable rotation imparted upon it.

Abstract: The power meter provides an analog output voltage which is proportional to ower for both sine wave excitation and all other excitation types. The circuit of the meter involves the use of electronic multipliers to produce the low-ampere product of voltage and current in real time, and sums the results to produce the total power output representation for all phases.

Abstract: The pressure of the atmosphere is sensed by a pressure transducer which causes a resistance to vary. The variance of this resistor is converted to a variable frequency. The number of cycles of this frequency in a set amount of time is counted by a counter and displayed by a digital display. An up/down counter is loaded with the count of the last digital readout in the previous cycle and counts down the number of cycles in the frequency of the next reading and displays the difference on a digital display or activates a sonic output if the countdown is greater than the stored previous count.
