Patent GB-2208053-A (GB)
Title: A gain controlled preamplifier
Inventor: SELF DOUGLAS
IPC: H03G3/12
Filed: 1987-08-11
Abstract: A preamplifier circuit for amplifying low impedance sources has a first amplifying stage comprising two transistors Q1 and Q2 connected as a differential pair and a second amplifying stage 4. The gain of the first stage is varied by a gain resistor RG and that of the second stage 4 is varied by a reverse logarithmic resistor, these two resistors being ganged together for control by a single control knob or slider. The gain of the first amplifying stage is set by the values of emitter resistors RE, the gain resistor RG, and two feedback resistors RF each coupling the first stage output 2 to the emitter of a respective one of the transistors Q1 and Q2 of the differential pair. The gain characteristic of the first stage is attributable to the potential divider action of the resistors RE,RG and RF and sharply rises in its high gain region, whereas the gain of the second stage 4 is the familiar curve, flattened in the high gain region, attributable to a reverse logarithmic resistor. The gains of the two stages thus combine to produce an overall gain law which is substantially linear in dB's with respect to the movement of the control knob or slider. The resistors RE may be replaced by current source transistors (Q3,Q4, Fig 3) and cascade converted transistors (Q5,Q6) can be provided. <IMAGE>

Title: A method and apparatus for monitoring the driver of a vehicle
Inventor: RITCHIE WILLIAM GEORGE DAVID
IPC: G08B21/06
Filed: 1988-02-13
Abstract: The invention concerns determining if the driver's eyes are open or closed and generating an alarm signal if the driver's eyes are found to be closed. In the method signals indicative of an image including the drivers eyes are sequentially generated and compared and an alarm signal is produced if a signal is received representative of an image from which the driver's eyes are absent. Each successive sequentially generated signal may be compared with the immediately preceding such signal, or with a reference signal. The apparatus used to generate the desired signals is said to be a video camera 10 the output of which is digitised at 18 and fed to a processor 20. In one embodiment the successive signals are stored at 22 and compared at 24 with their immediate predecessors. In another each is compared with a reference signal stored in the processor. The apparatus may includes means for delaying production of an alarm until a predetermined number of sequentially generated signals have been produced each indicative that the drivers eyes are closed and means 32 ,34 for disabling generation of an alarm in dependence upon the vehicle motion or driver action. The apparatus may further provide that the drivers face is illuminated by a light source 16 the output of which is adjustable to ensure substantially constant illumination of the drivers face. Preferably the video camera is sensitive to infra-red light and the light source is a source of such light. <IMAGE>
