Title: Arrangement for interfacing a keyboard with a microprocessor
Inventor: GARTH IAN MURRAY
IPC: H03M11/20
Filed: 1994-11-10
Abstract: An arrangement for interfacing a keyboard comprising an array of keys operatively associated with a matrix of rows (11 - 15) and columns (6 - 10) of conductive elements with control line terminals (P1 - P5) of a microprocessor (16) programmed to decode key operations from signal conditions applied to the control line terminals. Each row is connected to a respective control line terminal via a diode (D1 - D5) and each column is connected to a respective control line terminal. Pull-up resistors (R17 - R21) couple a voltage source to the columns. Upon operation of a key (22) a current path is established via an associated diode (D4) to a control line terminal (P2) rendered LOW by a scanning cycle routine of the microprocessor. The forward bias current of the diode causes another control line terminal (P4) to be pulled LOW. The microprocessor decodes the state of the two charged control line terminals and identifies the operated key in a known manner. The arrangement permits a reduction in the number of control lines required for a given number of keys. <IMAGE>

Patent GB-2308441-A (GB)
Title: Rotation Sensor
Inventor: GILES TERENCE GEORGE
IPC: G01D4/00
Filed: 1995-12-22
Abstract: A sensor for counting rotations of a Ferraris disk in an electricity meter, the disk having a broad stripe 18, comprises two IR LEDs 12, 14 and a central a photo-transistor 16 receiving light reflected from the disk. The LEDs are spaced in the direction of rotation by at least the width of the stripe, so that as the stripe passes across the detector, the output signal has shoulders on its falling and rising edges. By detecting this characteristic pattern and checking that the LEDs which contribute to the signal at the shoulders are in the correct sequence for the normal rotation, it is possible to detect false counts caused by jitter, tampering or changes in ambient light level. During production the LEDs are balanced by a calibration process so that the photodetector signal is essentially steady, despite the switching of the LEDs when the sensor is exposed to a normal reflective surface.
