Patent GB-2202702-A (GB)
Title: Analogue to digital converter
Inventor: JACKSON JOHN
IPC: H03M1/20
Filed: 1987-03-27
Abstract: A high resolution analogue to digital converter is provided, typically of 12 bit resolution, which has the speed of a full flash ADC but which has far fewer active components, typically 16 times less, and hence much lower power consumption. A coarse digital prediction 3 of the signal to be digitised is converted, DAC to analogue form and subtracted, 2, from the signal, 1. The difference, consisting of relatively few bits, is digitised, ADC, at speed and added, ADC, to the prediction, 5, to provide the full digitised signal 10. In many applications a prediction can be obtained from the immediate or longer term history of the signal. The input signal, 1, may be derived from an array of infra-red detectors viewing a scene. <IMAGE>

Patent GB-2198807-A (GB)
Title: Vibrator mechanisms
Inventor: WILLETTS DAVID JOHN
IPC: B06B1/10
Filed: 1987-11-18
Abstract: A vibrator mechanism includes a finger (9) which rides on a disc (7) which is bolted to one end of a shaft (1) so as to rotate eccentrically about the axis of the shaft (1) as the shaft (1) rotates. The other end of the finger (9) is pivoted, for rotation about an axis (A), to a housing (3) of the shaft (1). As the shaft (1) rotates the eccentric rotation of the disc (7) causes the finger (9) to oscillate about the axis (A). A roller (15) mounted in a block (13) rests on the finger (9) at the point at which the oscillating motion of the finger (9) is to be transferred by the block (13) to a member (12) to be vibrated. A telescopic ram (17) moves the block (13) and hence point of rest of the roller (15) on the finger (9) along the length of the finger (9) and thereby alters the amplitude of the vibrations transferred to the member (12). <IMAGE>
