Abstract: A switching power supply (100) having a power steering clamp (116) is disclosed. The power supply (100) may suitably include a pulse width modulator controller which controls a first switch for controlling the flow of energy into and out of a transformer (120). The power steering clamp (116) suitably includes a second switch, clamp diodes, and circuitry for driving the gate of the second switch. The circuitry for driving the gate of the second switch is preferably controlled by the pulse width modulator controller. Use of the power steering clamp (116) permits leakage energy to be rerouted subsequently to the transformer. This feature may improve the efficiency of the circuit and also avoids the need for heat sinks to prevent overheating of circuit components. Such a switching power supply (100) is particularly suitable for use in high density devices, such as a banknote or bill in high density devices, such as a banknote or a bill validator.

Abstract: A new and improved unshielded horizontal magnetoresistive head (100) is disclosed which utilizes multiple pairs of magnetoresistive elements (1, 2, 3, 4). The present invention provides a device which is characterized by reduced output signal undershoot amplitudes, and an increased central peak pulse amplitude, while not significantly affecting the resolution of the device. The device is also characterized by increased signal to noise and signal to interference ratios. Magnetoresistive elements (1, 2, 3, 4) utilized in the device may be fabricated and/or manufactured by simplified processes, resulting in fabrication, manufacturing and cost benefits for the magnetoresistive head. Any number of additional magnetoresistive head. Any number of additional magnetoresistive element pairs may be utilized dependent on the accuracy and resolution required by the specific application.

Abstract: A coin mechanism having a coin storage tube (102) and an optical sensor for sensing the level of coins in the tube, the sensor comprising a light source (108) arranged to direct a light beam across the tube, means for returning the beam across the tube and a light detector (112) for detecting the returned beam, characterised in that the means for returning the beam is a concave mirror (114) having a curvature such as to give the beam an area, where it approaches the detector, substantially greater than the effective area of the detector. This enables, in a compact sensor, the light intensity at the detector to be enhanced and at the same time the sensivity to misalignment of components to be reduced.

Abstract: A device for selectively routing coins (2) moving edgewise on to either of two paths (D, E), comprising a flap (12) lying generally in the plane of movement of a coin, the flap being pivoted (Y-Y) such that its upstream end is selectively movable between two positions to cause the coin to go either to one side or to the other side of the flap depending upon the position of the flap, a coin support (16) arranged to support a coin going to said one side of the flap, so that the coin continues edgewise (on path D) past the flap, and an opening into which a coin going to said other side of the flap will fall edgewise (on path E).

Abstract: A coin testing device comprising two parts (2, 4) which in an operating, closed, condition of the device define between them a narrow space (6) in which coins travel edgewise, and one or more coin sensor elements (12, 12', 14, 14', 16, 16') mounted on at least one of the parts, the two parts being capable of relative movement apart from each other for access to the space between them, characterised in that the two parts are provided with location-defining features (20, 20', 22, 22', 24, 24') at three positions which are spaced apart to form a triangle, that when the two parts are being brought together from their apart position they are sufficiently displaceable relative to each other to be able to adopt final closed positions determined only by contact between the location-defining features, and that means (28, 56) is provided for urging the parts towards each other at a position within said triangle. Accurate location of the two parts relative to each other is achieved despite manufacturing tolerances.

Abstract: A magnetically encoded card (2) has a recording track (6, 8) containing data (10, 14, 16, 18) which can be read and re-written by a card reader (30), and a further recording (12) at a much higher spatial bit density than the data (10, 14, 16, 18). The high density recording (12) is formed using a special write head capable of operating at greater bit densities than the head of the card reader used to write information to the card. The card (2) is deemed valid only if the presence of the high density recording (12) is detected by a read head (34) of the card reader.
