    摘要: In an injection-locked laser system, a timing system for assuring the locking of an injection-locked oscillator to the frequency of a master oscillator. The system automatically controls the firing of the injection-locked oscillator in accordance with the difference in time between the production of a master oscillator pulse and the time that a predetermined population inversion level has been reached in the injection-locked oscillator as measured by a predetermined level of fluorescence produced by the injection-locked oscillator.

    摘要: Jewelry, such as finger rings and earrings, which flash in synchronism with the wearer's heartbeat. A pulsed IR signal is directed into the wearer's tissue and a reflected or transmitted signal is monitored to determine when the wearer's heart beats at which time one or more light emitting sources in the jewelry flashes. The monitored signal is utilized to determine the wearer's heart rate. At least two light emitting sources are provided one of which flashes with each heart beat and the other flashes when the heart rate reaches or exceeds a predetermined range or increases faster than a predetermined rate. Preferred embodiments include three visible LED's (red, green and blue) and a micro-processor which calculates pulse rate and causes the red LED to blink on each pulse, the green LED to blink on each pulse when the wearer's pulse rate is greater a first threshold and the blue LED to blink on each pulse when the wearer's pulse rate is greater than a second threshold corresponding to extreme excitement. These threshold values may correspond to increased heart rates of typical persons engaged in exercise and love-making. The monitor may also be self calibrating to adjust the thresholds based on measurements of the wearer's heart rate over extended periods which would include periods of rest as well as periods of exertion or excitement. Other preferred embodiments vary the brightness of the LED's depending on the estimated blood pressure that also increases by about the same degree as pulse rate.

    摘要: A data gathering system comprising a single optical fiber having one or more modulators formed thereon, means for launching into the fiber an interrogating light pulse which propagates in a first direction, means for generating at each modulator an optical return signal which propagates in the fiber in a second direction opposite the first direction and which has an intensity which is variable in response to variations in an external signal incident at the modulator, and means for detecting and processing each such return signal. The return signal comprises a portion of the interrogating light pulse which is coupled into the fiber in the second direction via evanescent coupling. The return signal from each modulator (or array of modulators) is identified via time division multiplexing. A signal processing means may be coupled to the fiber for generating a unique return signal from each of one or more modulator arrays, each array comprising a selected subset of the modulators. In a preferred embodiment, each modulator comprises a looped section of the fiber having a coupling region in which the distance between adjacent fiber segments is variable in response to variations in an external signal incident thereon. In another embodiment, each modulator comprises a short fiber segment positioned adjacent to the main fiber and separated therefrom by a distance variable in response to pressure changes incident on the modulator.

    摘要: A level sensor for measurement of the level of molten metal in an electron beam evaporator which operates to sense directly the position of the point or line source of evaporant by detection of radiation such as light emitted therefrom. Compensation is provided for variations in electron beam deflecting magnetic field to avoid interpreting lateral movement of the point or line source from field variations as level changes. Compensation is also provided in the detection circuit for variations in detected light intensity that would otherwise provide an erroneous indication of level change. Detection of further conditions that produce unreliable level sensing and system inhibition in response thereto is provided as a safety feature.

    摘要: A system for multiplexing or demultiplexing pulsed laser radiation having an acousto-optical device which is electrically controlled to switch a common path of high pulse rate laser radiation between a plurality of spatially distinct paths for relatively lower pulse rate laser radiation at which the pulses are sequenced according to a predetermined time pattern. The acousto-optical element typically includes a Bragg cell which is electrically driven by a set of distinct frequencies, causing deflection of radiation passing therethrough at a predetermined set of angles whereby pulsed radiation on a single path may be distributed onto the plural separate paths or radiation on plural separate paths of time-sequenced pulses of radiation can be combined into a single path of augmented pulse rate. The control of the acousto-optical element may be provided by selectively switching the output of a plurality of fixed frequency oscillators of different frequency to the acousto-optical element in accordance with the pattern of pulses on the common or plural distinct paths or a voltage-controlled oscillator may be sequenced through a repeating set of frequencies which are sampled one or more times per sequence to develop an error signal resulting in feedback control over the oscillator to eliminate long-term drift.

    摘要: Apparatus for use with a standard television (TV) receiver for superimposing information or images over portions of the broadcast scene. Scynchronization signals are generated by locking onto the horizontal sweep electromagnetic interference (EMI) generated by all television receivers. A wideband noise (RF) burst is generated and coupled to the antenna input leads of the television receiver. The picture content of the TV scene at the time of the noise burst is disrupted and various effects are created by controlling the level of the noise bursts. By controlling the position of the RF noise, an image may be created and superimposed over any part(s) of the scene. The scene may be derived from any source, such as standard television broadcast, a video cassette recorder (VCR), electronic game or computer monitor. No modification of the television receiver is required, and no change to the apparatus is needed when the TV is tuned from one broadcast channel to another.
