摘要： A coin discrimination sensor having an excitation coil and two detector coils arranged to detect eddy currents in a passing coin. The excitation coil is provided a composite waveform formed by adding a low frequency signal (30 KHz) with a high frequency signal (480 KHz). The two detector coils are arranged at different distances from the passing coin, and are calibrated to eliminate the common-mode voltage when no coin is present. As a coin passes by the sensor, eddy currents are induced in the coin which result in phase and amplitude shifts in the low and high frequency components of the detector signal. The low and high frequency components are separated from the detector signal, and their respective phases and amplitudes are ascertained and compared against values stored in a lookup table. These values represent the composition, thickness, and diameter characteristics of known coins, and if the signature of the processed coin does not appear in the lookup table, it can be flagged as an invalid coin.

摘要： A coin processing system includes a coin processing machine configured to receive a plurality of randomly oriented coins in a coin input region thereof, process the coins, and determine a total amount of the coins. The coin processing system also includes a sensor configured to measure a pre-determined property associated with a component of the coin processing machine and/or an operational state of the coin processing machine and to output to a controller a signal related thereto. The coin processing system also includes an actuating device disposed to influence the pre-determined property. A controller is configured to monitor the signal output by the sensor and, responsive to a deviation of a value of the signal from an acceptable value for the signal, to execute an error recovery instruction set at least once. Execution of the error recovery instruction set by the controller causes an actuation of the actuating device to influence the pre-determined property to attempt to restore the operational parameter to a condition wherein the signal output by the sensor is within an acceptable value for the pre-determined property.

摘要： A four current transistor temperature sensor comprises a p-n junction, preferably the base-emitter junction of a bipolar transistor, which is driven with four different currents in a predetermined sequence. Each of the four currents induces a respective base-emitter voltage, which is measured. The temperature of the transistor is calculated based on the values of the four driving currents and the four measured base-emitter voltages. The four driving currents (I1, I2, I3 and I4) are preferably arranged such that I1=2*I3, I2=2*I4, I1/I2=A and I3/I4=A, where A is a predetermined current ratio. I1 and I2 produce respective base-emitter voltages which are subtracted from each other to produce &Dgr;Vbe1, and I3 and I4 produce respective base-emitter voltages which are subtracted from each other to produce &Dgr;Vbe2. When so arranged, the difference between &Dgr;Vbe1 and &Dgr;Vbe2 is entirely due to the effect of series base and emitter resistances rb and re. Therefore, the &Dgr;Vbe1−&Dgr;Vbe2 value provides a correction factor which enables temperature measurement errors due to rb and re to be eliminated.

摘要： For locating a ferromagnetic object, a device has a non-magnetic housing with a perimeter wall, a front surface, and a rear surface. The perimeter wall defines a chamber within the housing. A stop element is located within the chamber between the front surface and the rear surface. A magnet element is housed within the chamber and is movable between a resting position, where the magnet element is proximate the stop element, and an active position, where the magnet element is proximate the front surface. The device has a mechanism for returning the magnet element to the resting position in the absence of a ferromagnetic object located proximate the front end of the device.
