Abstract: 1285882 Analog/digital converters PLESSEY CO Ltd 17 Oct 1969 [17 Oct 1968] 49354/68 Heading G4H In an analogue/digital converter for an analogue input signal S (Fig. 1) comprising a plurality of stages each including a differential amplifier Al... A5, the input S n  to the amplifier of the nth stage is proportional to S-D¢- D 2/4 -. . . D m-1 / 2m-1  where D i  is the digital out- 4 put bit from the ith stage and is positive or negative in dependance on whether S i  is less than or greater than 0. As described the binary weighted fractions of each digital output signal are obtained by feeding e.g. the signal D i  via resistances weighted 2 i R to the lower stages the input S to each stage being fed via a resistor R. The first output bit Dl represents the polarity. In a modification to give a binary coded decimal output the input resistances have the value 1.6 R and a signal from a + 6 V source is also fed via a resistance of value 2À66 R to each stage. The feedback resistances connecting the units decade outputs to lower stages are ten times larger than the corresponding resistance for the tens decade outputs.

Title: Ultrasonic system for detecting absence of movement
IPC: G08B13/16
Filed: 1965-12-21
Abstract: 1,072,090. Stopping trains. CLEVELAND TECHNICAL CENTER Inc. Dec. 21, 1965 [Dec. 21, 1964], No. 54064/65. Heading B7N. [Also in Divisions H3 and H4] In a system for detecting the absence of movement of a body within a predetermined period of time, ultrasonic energy is transmitted towards and received after reflection from the body and an alarm is actuated if a Doppler frequency shift in the received signal is not detected within that period. In the illustrated embodiment (Figs. 1 and 2, not shown), for actuating an alarm and applying the vehicle brakes if the operator of a vehicle makes no conscious movement within a predetermined time period, signals received by a transducer (17) are amplified and mixed, in circuitry (18) with a signal at the transmitted frequency. The resulting Doppler signal output from the mixer (if the operator moves) is amplified, rectified by diode 152, and holds transistor 170 conducting, thereby ensuring capacitor 175 is discharged. If no Doppler signal occurs within the predetermined time period, capacitor 175 charges to a voltage at which unijunction transistor 180 is triggered into conduction, the charge time defining the period. The triggering of transistor 180 fires silicon-controlled rectifier (SCR) 186, thus energizing an alarm-actuating relay 190. The firing of SCR 186 renders transistor 198 non-conductive, whereby capacitor 206 charges over a second predetermined time period. If the operator fails to reset the alarm by opening switch 192 within this second period, the voltage on capacitor 206 reaches a value at which unijunction transistor 210, and hence SCR 218, are rendered conducting. The firing of SCR 218 energizes a vehicle-brake-actuating relay 222.
