Abstract: A method and apparatus are disclosed for regulating the operation of a TWT. The TWT regulation is achieved by detecting the operating condition of the TWT, e.g., by measuring dynamic gain, and regulating feedback of the TWT output in response to the TWT operating condition. The invention is preferably implemented so as to augment the TWT input drive from an exciter source to induce the TWT to drive itself into saturation. The inventive technique comprises determining whether the TWT is operating in a desired operating condition, e.g., saturation, feeding back to the TWT input a portion of the TWT output power to the TWT input, and regulating the feedback signal to keep the TWT operating in the desired condition. Determination of whether the TWT is operating in a saturation condition may be affected through measurement of the TWT dynamic gain. The invention permits dynamic management of the feedback to accommodate variations in gain of the TWT, e.g.

Abstract: A radio frequency (rf) probing technique is disclosed for determining whether an rf signal injected into one termination of a series-connected string of photovoltaic (PV) modules has been conducted to successive positions in the string. A signal generator is provided for generating a carrier signal which is modulated by an audio frequency tone. The generator is capacitively coupled to one of the terminations of the module string to inject the modulated carrier signal into the string. A receiver is tuned to the carrier frequency and adapted to demodulate the audio tone. Rf signals are coupled to the receiver by a probe including a shielded plate electrode, which may be disposed adjacent the active surfaces of successive ones of the modules in order to detect the presence or absence of the rf signal at that point in the string. An alternate technique is disclosed, whereby a measurement of the capacitance-to-ground of the string is compared against a reference capacitance value of a fault-free system.

Abstract: A prism assembly for a single light valve, full-color projector is disclosed. The prism assembly is adapted to polarize and separate the white illumination light into the three primary colors. Three separate input images corresponding to the information for the red, green and blue components of the full image are applied to separate regions of the light valve photoresponsive layer. The prism assembly comprises three channels, one for each of the primary colors. Each channel polarizes the illumination light into P-polarized colored light which is reflected onto the region of the light valve corresponding to the respective input image. The illumination light in each channel is reflected by the respective region of the light valve as respective beams each including an image bearing component of one polarization state and a second beam component of the opposite polarization state.

Abstract: A method is disclosed for synchronizing the operation of frequency hopping, spread spectrum communication devices in a network. One device (the "NTU") is deemed to be keeping the network time, to which the other devices must synchronize in order to communicate over the network. In a broadcast mode of the method an unsynchronized unit (a "RTU") operates in an idle state to receive on a discrete set of receive frequencies. The total communication time period is divided into intervals, and a unique synchronization code is generated for each time interval which defines the idle state frequencies and time information transmit frequencies to be employed in accordance with the method. The time kept by the RTU is assumed to within a predetermined number of time interval of the present network time interval.

Abstract: An M-bit all-capacitive analog-to-digital (A/D) converter is disclosed which includes 2.sup.N switched capacitors of substantially identical capacitance for use in determining the N most significant bits. Each of the capacitors have one terminal connected to a common node and its other terminal switchable to either ground or a positive reference voltage. At the beginning of a conversion cycle, the common node is at a potential indicative of a sampled analog input voltage, a first group of 2.sup.N-1 capacitors are switched to ground, and a second group of 2.sup.N-1 capacitors are switched to the positive reference voltage. For a given conversion cycle, selected capacitors of one of the capacitor groups are sequentially switched to drive the common node voltage to ground. A method is also disclosed for converting analog signals to digital signals utilizing parallel capacitive elements of substantially identical capacitance.

Abstract: A mounting and stowage mechanism erects a head-up display combiner into the pilot's line-of-sight. One end of a crank is mounted on the combiner and is pivoted on a first link which is pivoted to a frame. A support link is pivoted on the combiner and on a drag link which is pivoted to the frame. A connecting link is pivoted to both the first link and the outer pivot of the drag link to complete a compound 4-bar linkage which controls the path of the combiner between the erected position and a stowed position out of the pilot's line-of-sight. Manual control is through a handle which is mounted on a slider for linear motion and is connected to the end of the crank remote from the combiner. The mechanism is rendered insensitive to motion in the combiner-erect position by assuring that the instant centers of the links carrying the combiner are located at twice the focal length from the combiner along a line that runs through the center of curvature of the combiner and its focal point.

Abstract: A bistatic sonar employing LMS adaptive spatial prediction is used to process against surface reverberation from the convergence zone (CZ). Hydrophones spatially separated from the primary array are used as references. The critical behavior exploited by the invention is that since the reverberation may be viewed as an extended source for the reverberation, the correlation drops off with separation between the reference and primary sensors, while it stays a constant for the plane wave target return. The reverberation is non-stationary, functionally dependent on the signal (even though the back scatter is statistically uncorrelated with the signal), and spatially extended over the sector of the CZ annulus cut out by the transmitter azimuth beamwidth. The detection of the target is based on the sudden appearance of one strong target point source within a densely packed region of weak point sources that have been constantly present and whose sum is much larger than the target.

Abstract: A narrow-band phase shift beamformer system is disclosed. The outputs from the elements in a transducer array are each divided into two components whose amplitudes are respectively proportional to the sine and cosine of the required phase shift, which are then processed so that the steered beam may be formed by coherent summation. The proportionalities of the respective sine and cosine components are achieved by switched capacitor circuits, which are preferably implemented by LSI circuits, permitting substantial hardware savings and yielding highly accurate component proportionalities.

Abstract: A circuit for reducing noise and increasing the reliability of touch panels involves the use of a supplemental noise or electromagnetic interference pickup lead which extends generally coextensively with the parallel connected outputs from a series of successively coupled photodetectors and a high pass filter for substantially reducing the noise signals created by variations in the level of ambient light. When the photodetectors output is connected to one of the inputs of a differential operational amplifier, and the compensating pickup lead is connected to the opposite polarity other input, the noise is substantially cancelled out, and a cleaned-up photodetector pulse is provided. A pulse forming circuit squares up the photodetector output signal pulse; and a hysteresis type storage or buffer 15 circuit is employed to indicate the presence or absence of photodetector output signals, from successive photodectors, thereby indicating whether or not the light beams are interrupted either fully or partially.
