Abstract: 1528640 Transistor amplifiers and oscillators HITACHI Ltd 17 Feb 1976 [28 Feb 1975] 06233/76 Heading H3T An amplifier, Fig. 5, comprises at least one amplifying IGFET having its gate connected to an input terminal and its drain connected to an output terminal, a bias resistor R F  connected between the input and output terminals of the amplifier, first and second capacitors C G1 ,   C G2  respectively, connected in series across the power supply terminals, and defining a voltage divided from the supply voltage equal to a bias voltage produced via the bias resistor, the divided voltage being applied to the input terminal. C G2  may for example be a parasitic capacitance, and in the absence of C G1 , the bias potential of the input terminal would be slow to follow a transient decrease in the supply voltage - V DD . In the circuit of Fig. 5, with equivalent FET's Q N , Q P , the bias voltage will remain proportional to VDD provided that C G1  is made equal to C G2 . In another embodiment, Fig. 4, a quartz crystal oscillator circuit 1 for a watch, comprises an amplifier as above having a positive feedback path which includes capacitors C D , C G <SP>1</SP>. The value of a capacitor C G <SP>11</SP> is selected such that the biasing of the gates of Q N1 , Q P1  is proportional to the supply voltage V DD  even under transient conditions. A transient drop in supply voltage may occur when the motor winding M of the watch is pulsed. The quartz oscillator QO is used as an inductive element, and may alternatively be substituted by an inductor.

Title: Heart rate meter based on heart muscle contractions - uses two injection electrodes and two scanning electrodes
IPC: A61B5/308
Filed: 1977-02-04
Abstract: The heart rate and rhythm meter has four electrodes fitted to the patient being monitored. Two are injection electrodes applying a high frequency current. The other two are scanning electrodes between the first pair, coupled to a detector, filter and shaping channel for the rheographic signal. This channel is coupled to a heart rate counter. A channel is provided to eliminate variations in the lung impedance. It is coupled to the inection electrodes and supplies a rheographic lung signal. The detector filter and shaping channel has a recombination stage in which the rheographic lung signal is subtracted from the rheographic signal. The meter is used for monitoring pacemaker patients. The system is absolutely safe as it relies on mechanical contractions of the heart muscle rather than generated electrical signals.

Abstract: A multi-mode pacemaker includes a microprocessor 100 and a memory 102 programmable with a variety of processes for stimulating a heart and/or a sensing and transmitting to an external device conditions of the heart or pacemaker. The microprocessor controls a multiplexer 106 to input via a scaling amplifier and a/d converter 108 signals from atrial and ventricular leads 17, 19, the power source 126, a reed switch 23 operable by an external magnet, or redundant leads on lines 138d,e. The output comprises latch drivers 134 a-d with respective output select switches 130 a-d selectively operable to supply stimulation pulses to the leads or allow sensing. External apparatus 104 may transmit coded information to change the stored program or operation of the reed switch may select a different program starting address. Pulse width, rate and amplitude may be controlled in response to sensed heart activity or power source level and different pacing modes (demand, asynchronous, etc.) or multi-site pacing to disrupt arrhythmias may be selected automatically or externally. In an aid converter 308 (Figure 8), counter 400 counts up the output of VCO 402 controlled by unknown signal V(X) and then counts down to zero the output of VCO 402 then controlled by reference EREF and during such countdown a counter 412 counts clock pulses so that when counter 400 reaches zero the output of counter 412 depends on V(X) but not on the scale factor of VCO 402. <IMAGE>

Title: Distortion detector for pipelines, building materials etc. - uses optical fibre placed along object so that distortion causes change in transmission characteristics
IPC: G01K5/72
Filed: 1984-04-27
Abstract: An optical fibre (3) runs along the component (1) to be monitored. At intercals it is fixed to the component. Between fixing points (4), the fibre is bent over obstacles (2).
