Patent GB-2140643-A (GB)
Title: Optical fibre system
Inventor: CHOWN DAVID PHILIP MARTIN
IPC: H04B10/43
Filed: 1983-05-19
Abstract: @ In an optical fibre receiver, the modulated light falls on a p-i-n diode (PD) connected to the input of an operational amplifier (A). This amplifier is shunted by a load resistor (R), which in turn is shunted by a non-linear Schottky diode (SD). This prevents a large pulse from spoiling the sensitivity of the receiver to a following smaller pulse.This also provides the receiver with a low pass response having a relatively long time constant. In addition to this, the a.c. coupling response for the connection to the next stage of the system has a relatively short time constant. These two time constants combine to give an overall characteristic with a relatively narrow bandwidth, which enhances the above effect.Finally, when the line muting function is needed, as between messages, the bit stream as detected includes a double amplitude pulse whose detection initiates the line muting function. This can be implemented by a double length pulse included in the bus bit stream which is so detected as to give a double amplitude pulse.

IPC: H01C7/04
Filed: 1983-12-03
Abstract: Thin film negative temperature coefficient (NTC) thermistors (10, 11, 12, 13, 14, 15) can be fabricated with mutual thermal coupling whilst remaining electrically isolated to form slow speed logic devices. If both thermistors 10 and 11 are driven to the negative resistance state by applied voltages they will heat thermistor 12. This structure functions as an AND gate. If either thermistor 13 or thermistor 14 is driven to the negative resistance state thermistor 15 will be heated. This structure functions as an OR gate. Switching speeds are fast enough for e.g. protective circuits for electrical equipment. <IMAGE>

Title: Shape sensors
Inventor: PATEL MINOO HOMI EDALJI
IPC: G01B11/245
Filed: 1984-03-29
Abstract: A contactless shape sensor comprises a ring (3) to encircle the body the shape of which is to be determined, the inner surface (7) of the ring having at least one array of electromagnetic radiation (EMR) emitters encircling the ring and a corresponding array of EMR sensors. The EMR emitters are capable of emitting a signal over a wide angle and the EMR sensors have a wide field of view. When an EMR emitter A is switched on, the EMR sensors at B and C detect the edges of the shadow cast by the body thus defining lines AB and AC tangential to the shape (1) within the ring. By switching the emitters (A) around the ring in turn further tangential lines to the shape can be defined, and the resulting information can then be used to re-create the image of the body encircled by the ring. The device is particularly useful for determining the shape of a person's leg at a location where an amputation has been made. <IMAGE>

Title: Inductive loop vehicle-sensing
Inventor: JEFFERIS BRIAN CHARLES
IPC: G08G1/042
Filed: 1984-11-05
Abstract: In an inductive loop detector for sensing the presence of vehicles, in which a road loop is coupled as part of the inductance in the tank circuit of an oscillator, the operating frequency of the oscillator is tuned by application of a parallel digital number, (e.g. from a microprocessor) to a tuning control circuit which changes the inductance in the tank circuit in response to change in the digital number. In one arrangement, the digital number is applied to a controllable network, such as a digital-to-analog converter, having a voltage output or voltage characteristic that varies according to the digital input, and the varying voltage or voltage characteristic is employed to vary the tuning inductance coupled to the oscillator. In another arrangement, the road loop is coupled to the oscillator tank circuit by a multi- tap transformer the transformer ratio of which varies in accordance with the applied digital number. <IMAGE>

Patent GB-2175399-A (GB)
Title: Selective chemical detection by energy modulation of sensors
Inventor: STETTER JOSEPH ROBERT
IPC: G01N31/10
Filed: 1986-05-08
Abstract: A portable instrument for use in the field in detecting, identifying, and quantifying a component of a sampled fluid includes a sensor which responds to the component of interest or a derivative thereof, means for supplying energy to the sample before it is applied to the sensor, and modulating means for continuously varying the energy supply (and hence the reaction rate) between two values sufficient to produce the chemical reaction. In response to this modulation, the sensor produces a modulated output signal. When the energy is supplied by a heated filament and the sensor is electrochemical, the sensor output modulation is a function of the activation energy of the chemical reaction, which activation energy is specific to the particular component of interest and its concentration. Microprocessor means compares the modulated output signal with standard responses for a plurality of components to identify and quantify the particular component of interest. In particular, the concentration of the component of interest is proportional to the amplitude of the modulated output signal, while the identifying activation output energy of the chemical interaction indicative of that component is proportional to a normalized parameter equal to the peak-to-peak amplitude divided by the height of the upper peaks above a base line signal level. Other sensors and forms of energy modulation are disclosed. <IMAGE>
