Abstract: 1,234,291. Pulse modulation circuits. HAWKER SIDDELEY DYNAMICS Ltd. 26 June, 1969 [26 March, 1968], No. 14545/68. Heading H4L. A pulse width modulator is provided with means for keeping the pulse repetition frequency constant. An input signal V1 is supplied to an integrating amplifier 12 operating a hysteresis switch 21 which assumes a first state when its input reaches an upper level and remains in that state until its input falls to a lower level and it assumes a second state. The hysteresis switch controls an electronic switch 20 so that in the first state the output terminal 19 is connected to a voltage source V2 and in the second state is connected to a source - V2. The output on terminal 19 is also supplied via resistor 18 to the input of the amplifier 12 so that the polarity of the sum of the two inputs changes and the amplifier oscillates, the output V out  having a mark-to-space ratio dependent on the input signal V 1 . In order to prevent the unwanted frequency change which normally would occur, a pulse generator 22 derives pulse trains B, C, Fig. 2, from pulses A having a repetition frequency higher than the maximum frequency which would be reached by the modulator when the mark-space ratio is unity. The pulses B, C are supplied via oppositely poled diodes 26, 27 respectively to the input of the hysteresis switch so that when the mark-space ratio is greater than one, Fig. 2D, the positive pulses on the combined input take the input above the upper level 28 the negative pulses having no effect since they occur after the input has changed over on reaching the lower level 29. Similarly, when the mark-space ratio is less than one, Fig. 2E, the negative pulses synchronize the operation and the positive pulses are ineffective.

Abstract: 1,259,223. Training vehicle drivers. IOWA STATE UNIVERSITY RESEARCH FOUNDATION Inc. 2 March, 1970, No. 9952/70. Heading B7H. [Also in Division G4] In a driving simulator including a movie projector for projecting a film 18 portraying a series of driving situations on to a screen in view of a driver station 12 at a drive training unit 10 having simulated driving controls, there is provided a digit-tracking adaptive stressor unit which subjects the trainee driver to an auditory loading by detecting and evaluating the driver's verbal repetition of a series of spoken digits as he is simultaneously engaged in controlling the simulated vehicle. The adaptive stressor unit plays a continuous series of " zeroes " and " ones " selected at random from two channels on an endless recording tape 30 to the driver over a single earphone on a headset 16. A microphone 24 detects the verbal responses of the driver and converts them into electronic waveforms fed to an auditory pattern recognition system which utilizes three different characteristics of the spoken word in combination to determine by a majority decision whether a zero or one or neither of these was said by the driver. The spoken words are compared with those played from the tape and if correctly repeated the rate of word presentation is automatically increased, but if they are repeated incorrectly the word rate is reduced. Errors are counted and the word rate recorded on a paper strip recorder for subsequent analysis. The simulated controls on the trainer unit 10 are electrically linked to a comparator logic unit which registers operation of the brake, clutch and accelerator pedals and steering wheel, turn signals, light switch operation, and the driver's  glance direction which is sensed by accelerometers on the headset 16. The film 18 has a sound track 20 and carries an added ferrite strip 22 on which twenty-two tones detectable as the film runs through the projector provide twenty-two channels for driving control commands which are decoded by a decoder unit and compared by the comparator logic unit with the actions of the driver. Errors are recorded on magnetic tape and by the paper strip recorder and are indicated to the driver by indicator lamps on a display panel on the trainer unit 10. One of the command channels on the film 18 provides a frequency signal which is compared with a signal from a reference oscillator by a frequency discriminator to provide an error signal for controlling the speed of the projector motor.
