摘要： An optical target is acquired by an optical scanning system according to an in-band target frequency in an input signal from an optical scanning device. Both the in-band energy level and the out-of-band energy level of the input signal from the optical scanning device are determined. These two energy levels are compared and a possible detection of the target is determined according to this comparison. A minimum threshold of in-band energy is required in order for the possible detection to be confirmed.

摘要： A low power coin discriminator detects and identifies the denomination of a coin to activate a parking meter, telephone, or vending machine device. Initially the device is in a low power, dormant state. Insertion of a coin into the discrimator trips a switch which produces a wake-up pulse which turns on a microprocessor. The coin falls upon a piezoelectric element, a signal from which causes the microprocessor to activate a photoelectric sensor. The coin moves through the photoelectric sensor which determines the net cross-sectional area of the coin. The microprocessor samples the output of the photoelectric sensor to detect the minimum light incident upon the sensor at the point of maximum eclipse of the light beam. The microprocessor also samples the output of an integrator which integrates the output of the piezoelectric element to produce a numerical value proportional to the mass of the coin. If the output of the photoelectric sensor indicates that the coin is within acceptable limits then the measured mass of the coin is also compared to the corresponding limits. If the coin is deemed to be valid, its denomination is recorded in a conventional manner. Once the discrimination process is complete the circuit automatically returns to its original low power, domant state.

摘要： A method and system for acquiring an optical target affixed to a surface of a package with an optical scanning device. Height information associated with the height of the surface of the package is sensed and a height signal representative of a scanning distance between the optical target and the optical scanning device is generated. The package surface is scanned with the optical scanning device to generate an optical target input signal. The optical target input signal is converted in accordance with a first sampling frequency to provide a converted input signal, and a second resampling frequency is adjusted in accordance with the height signal. The converted input signal is reconverted in accordance with the second resampling frequency to generate a frequency shifted optical target signal, and the optical target on the surface of the package is acquired in accordance with the frequency shifted optical target signal.

摘要： A switch (10) which uses optical signals propagating through an air media is disclosed. Transmitters (14a-14n) radiate light along projection openings (40) through a solid, opaque housing (12). The projection openings (40) parallel each other and substantially reside in a lower plane (32) within the housing (12). Periscopic plugs (30) reflect such light upward along an intermediate direction (38) within the plugs (30) and out from the plugs (30) into incidence openings (42). The incidence openings (42) parallel each other and substantially reside in an upper plane (34) within the housing (12). Optical receivers (16a-16n) receive light propagating in the incidence openings (42). The incidence openings (42) reside substantially perpendicular to the projection openings (40).
