Abstract: SPLIT-BAND REDUNDANT AMPLIFIER SYSTEM                      ABSTRACT   A split-band, redundant amplifier system is disclosed.  The system has at least two identical amplifiers (1, 2) each capable of amplifying signals having fequencies within a predetermined pass band. A first filter (3) divides signals into at least two contiguous split-bands within the pass band.  A second filter (5) combines the signals in the split-bands.  In normal operation, the amplifiers are connected in parallel between the two filters, and each amplifier amplifies signals in only one of the split-bands.  Switches (SW1, SW2, SW3, SW4, SW5, SW6, SW7, and SW8) are connected to the amplifiers and the filters and are operative to selectively connect an input signal to the first filter or to one of the amplifiers and to selectively connect the output of the second filter or the output of one of the amplifiers to the output of the system.  A sensing circuit (7) is connected to the outputs of each of the amplifiers and detects when an amplifier becomes inoperative.  When an amplifier becomes inoperative, the sensing circuit disconnects the inoperative amplifier from the first and second filters and connects an operative amplifier to the input and output of the amplifier system.

A DC motor is provided with a bidirectional driving circuit, a servo circuit for controlling the driving circuit, and a rotation detector associated with the for shaft to provide a phase signal that depends, in magnitude and polarity, on the particular rotational angle of the shaft, regardless whether the motor is turning.  A stop control circuit then includes an amplifier whose output varies according to the phase signal, and a switch that normally provides the servo signal to the driving circuit, but, upon command, switches over to provide thereto the output of the amplifier as a brake signal.  Alternatively, the rotation detector can include two sensor elements separated by   and the stop control circuit can include an inverting amplifier, a non-inverting amplifier coupled to one of the sensor elements, and a switch circuit with inputs coupled respectively to these amplifiers.  A comparator provides a switch signal to the switch circuit in dependence on the phase signal from the other sensor element.  In another embodiment, a differential amplifier provides a brake signal in dependence upon both the phase signals from the two sensor elements.

Abstract: Abstract In a pulse radar apparatus target returns are detected, sampled, digitised per range quant and frequency analysed. The apparatus comprises a cell classification unit (5) for deriving from the spectrum of the target returns a cell classification signal, whose logical values indicate that the target returns within a radar cell are classified, in the first instance, to be from a moving target and from a fixed target. In a microprocessor (15) the cells, which collectively cover one single target, are combined to form a cluster, while a signal representative of the target covered by the cluster is determined. Furthermore in the microprocessor (15) a cluster classification signal is derived, whose logical values indicate that the target returns within the cluster are classified to be from a moving target and from a fixed target. The signal representative of the target covered by the cluster is read out if it is derived from target returns classified to be from moving targets.

Abstract: ABSTRACT      A stop-light monitor device comprises a source of cur-rent, a lighting circuit connected with the source and hav-ing a stop-light switch actuated by the brake pedal.  The lighting circuit has incandescent lamps which are energized when the brake pedal is depressed. A magnetic reed switch is connected to control a solid-state switch which in turn controls a pilot light that becomes illuminated when the solid-state switch is closed in consequence of the reed switch being opened.  A current-sensitive means connected with the lighting circuit, opens the reed switch in response to normal energization of the stop lights, whereby the pilot lamp is energized.  If a stop light burns out, the reed switch closes, opening the solid-state switch whereby the pilot light is extinguished, giving an indication of the mal-function.  The advantage of the present invention over the devices of the prior art is that the monitor device can be connected to the existing wiring of the vehicle with very simple modification thereof, involving only breaking one exist-ing lead and connecting the resulting ends to two terminals of the device.  In addition, malfunctions of the stop lights or their associated wiring are positively detected, regard-less of whether such malfunctions are in the nature of short circuits, or burn-outs in one or more of the bulbs.
