摘要： A multi-function detector has at least two different sensors coupled to a control circuit. In a normal operating mode the control circuit, which could include a programmed processor, processes outputs from both sensors to evaluate if a predetermined condition is present in the environment adjacent to the detector. In this mode the detector exhibits a predetermined sensitivity. In response to a failure of one of the sensors, the control circuit processes the output of the remaining operational sensor or sensors so that the detector will continue to evaluate the condition of the environment with substantially the same sensitivity.

摘要： An optical signal receiver for rapid and error free translation of optical signals into electrical signals is disclosed. The receiver is coupled to a light source. The light source is amplified and then split into two segments. One of the segments is delayed by a specific amount of time. Both segments are optically coupled to a photo detector. Each photo detector is coupled in parallel and are connected by two output terminals. When the voltage output by each photo detector is equal, the output terminals are balanced and will not have any voltage. The circuit will provide a voltage output on the terminal only on differential photocurrents sensed by the detector elements. The quiescent magnitude of the voltage output is a function of the value of the reverse bias voltage applied by the two voltage sources.

摘要： The present invention relates to a transmission method and device for efficient compression of digital data. The invention uses an optoelectronic coupler to receive light signals from a light transmitter at two bandwidths. A modulated signal generator is coupled to the transmitter which coverts voltage phase data signals to light signals. The data signals are modulated with a plurality of master profiles and subprofiles with different cycle time variations. The optoelectronic coupler has a pair of photodiodes. Light filters disposed on both diodes allow either the first or second bandwidth of light to pass. Conductors electrically couple the anode of the each photodiode to the cathode of the other photodiode which produce the voltage phase signal. A signal receiver is connected to the coupler and decodes the voltage-phase signal.

摘要： An image processing system for capturing and compressing images into a digital format is disclosed. The system has an array of imaging pixel elements which consist of two photodiode detectors (Opsistor). One photodiode detector is a capture detector while the other detector is a reference detector. The capture detector has an anode electrically coupled to the cathode of the reference detector. The cathode of the capture detector is electrically coupled to the anode of the reference detector. An image may be compared to a reference image detected by the reference detector. Different levels of light between the captured image and the reference image change the electrical output of the opsistor. Image compression is facilitated since only pixel elements which change from frame to frame need be stored. Additionally, a processing and compression circuit may use column and row scans to eliminate unchanged pixels and store only pixels with different light levels between images.

摘要： The Present Invention relates to methods and systems particularly useful in electrical products used to monitor and detect very weak signals. These products include, for example, night vision binoculars and remote listening devices. More specifically, the methods and systems of the Present Invention provide a signal conditioning technique that attenuates electrical noise generated within the product while at the same time preserving the integrity of the input signal. This provides a high signal-to-noise ratio within the product electronics and a dramatically clear final image. The Present Invention includes a method and system for chopping or splitting an input signal into two components, tagging each of the split signal components with opposite polarities, and a second reverse chopping step that combines the split and tagged input signal components into a restored input signal. The combining step, in addition to restoring the original input signal, cancels and attenuates internally generated, and untagged, electronic noise, providing image quality and detection in an efficient and economical manner that could not be obtained in the past.

摘要： An optical operational amplifier is disclosed. The operational amplifier has a first photodiode with an anode and a cathode. A second photodiode with an anode coupled to the cathode of the first photodiode, and an anode coupled to the cathode of the first photodiode to form an output terminal. A resistor is coupled in parallel with the first and second photodiodes. The inputs to the operational amplifier are light sources which generate different currents in the first and second photodiodes. The output voltage from the output terminal is a function of the difference in currents across the first and second photodiode. The output voltage is amplified in proportion to the value of the resistor. The basic optical operational amplifier configuration may be used in a variety of useful circuits. One example is the use of the amplifier in a position sensing device which determines position of a light beam by the output of photodiode sensing elements. A second example is the use of the operational amplifier in a retinal stimulator device. The output waveform of the operational amplifier may be shaped by the resistor and added capacitative elements to be more compatible with retina cells.
