  • Patent number: 4695752
    Abstract: A baseband receiver with a range gate interval in the order of nanoseconds. A tunnel diode, set to the low level state, is coupled across the output terminals of a bridge that is balanced in the absence of a received signal, during the range gate interval. Signals received by an antenna are coupled to a tunnel diode in an arm of the bridge causing it to change from its low level state to its high level state thereby unbalancing the bridge and establishing a voltage at the output terminals of the bridge that fires the tunnel diode coupled thereacross.

  • Patent number: 4688041
    Abstract: A method and apparatus for detecting a short pulse signal in the presence of an interfering jamming signal wherein the jamming signal is utilized as the local oscillator in a diode mixer when it is received at a sufficiently high level for efficiently mixing with a short pulse signal. When the received jamming level is insufficient to act as a local oscillator, an internal local oscillator signal is coupled to the diode to maintain an efficient mixing operation.

  • Patent number: 4678970
    Abstract: An electron beam magnetic deflection system capable of raster and stroke deflection and providing minimum power dissipation in raster mode. Automatic switching of the voltage demanded in raster mode is obtained by continuously sampling the yoke current, the power supply voltage being switched in magnitude and polarity corresponding to the direction of change and polarity of the yoke current. By returning energy stored in the yoke to the power supply during portions of the raster cycle, power efficiency is substantially enhanced.

  • Patent number: 4665401
    Abstract: A high frequency target seeking device, using a stabilized reflector antenna, performs range search and tracking functions and target angle search and tracking functions. A technique is provided for target range discrimination using several narrow band i.f. filters, also thereby improving signal-to-clutter ratio and signal-to-receiver noise ratio. Target search is accomplished with simultaneous range and antenna azimuth scanning, with the range bins and the antenna beam swept across the target. A multiplexer selects the range bin having signals indicative of the target. Target range tracking is accomplished by the multiplexer additionally automatically selecting range bins adjacent to the target's range bin and comparing their output signals. Antenna stabilization is accomplished utilizing signals from vehicle pitch, roll, and yaw rate sensors, and antenna elevation and azimuth rate and angle sensors.

    Abstract: A multibeam acoustic apparatus utilizing a linear array of hydrophone elements in a sonar system includes a cascaded ladder capacitance-inductance network for coupling electrical signals to and from the individual hydrophone elements. The hydrophone elements are connected in series and the natural capacitance of these elements provides the capacitive characteristics of the network. Shunt inductors supply the inductance characteristics and provide a phase characteristic inversely related to frequency. Variable cumulative phase delays are provided for signals applied to successive hydrophone elements whereby a sonar beam is formed in a direction determined by the frequency of the exciting signal.

  • Patent number: 4651563
    Abstract: An apparatus for detecting jet engine failures during aircraft flight. Low and high speed rotor rotation velocities of one engine are compared with low and high rotor rotation velocities of other engines and the difference between them utilized to determine engine failure. Equivalent low speed rotor velocity of an engine is computed from the high speed rotor velocity of that signal. This computed value is compared with measured low speed rotor velocity of the same and of different engines. Differences between the computed values and the actual values are compared to a computed threshold, which allows for normal differences between engines, to determine the operational state of the engine. Additional engine testing is performed by comparing low speed rotor rotational velocity to a computer windmilling value for each engine.

  • Patent number: 4644749
    Abstract: A controller for maintaining a motor operation at a desired rotational speed utilizes a phase locked loop that receives input signals from a tachometer coupled to the motor shaft. Reference frequencies for the phase locked loop are generated by a voltage control oscillator in response to voltages selected in accordance with the desired motor speed. These selected voltages are coupled to the motor speed control to establish a motor speed within the lock-in range of the phase locked loop. Tachometric feedback is applied in parallel for the phase locked loop. The open loop drive provided by the selected voltage guarantees degraded open loop control of the motor should the control circuit fall.

  • Patent number: 4644662
    Abstract: An inclinometer includes two coplanar electrodes positioned within a chamber of a metallic housing containing a high relative dielectric constant fluid and a gas. With the inclinometer positioned on a level surface equal areas of the two electrodes are immersed in the dielectric fluid creating two equal capacitors formed by the electrodes and the metallic housing. When the inclinometer is rotated through an inclination angle, unequal areas of the electrodes are immersed in the fluid causing a capacitance differential that is a measure of the inclination angle.

  • Patent number: 4642501
    Abstract: A magnetic actuator for providing a single-axis, noncontacting force capability with unconstrained cross-axis mobility utilizes flux feedback force linearization. Electromagnets cooperating with an armature suspended therebetween are energized by a bias flux and a signal derived from flux densities sensed in the air gaps. The bias flux density may be optimized to minimize the peak power required by the actuator. The flux density signals are applied in a closed force loop to provide a net force directly proportional to the commanded flux.

  • Patent number: 4642529
    Abstract: Apparatus for providing precise convergence measurements of electron beams in a CRT display by sensing the displacement of brightness peaks as an array of phosphorescent regions are sequentially illuminated by energy from the electron beams deflected by the deflection apparatus of the display system and an independent external time varying magnetic field applied by enclosing the CRT housing within a pair of external coils. Convergence is calculated by calibrating the recorded brightness peaks as a function of beam displacement. The system is adaptable to measuring both vertical and horizontal components of convergence as well as linewidth. The apparatus operates independently of and does not require interruption of dynamic functions which operate in synchronism with the deflection circuits, such as dynamic convergence correction.
