  • Patent number: 5349359
    Abstract: Spatially variant apodization is a digital image processing technique for eliminating sidelobes produced by Fourier transform of finite data sequences without compromising mainlobe width. This process allows each sample or pixel in an image to receive its own frequency domain aperture amplitude weighting function from an infinite number of possible weighting functions. In its simplest form the weight is a function of the negative of the current sample divided by the sum of the neighboring samples, and the function is limited to a predetermined range such as the range between zero and one half.

  • Patent number: 5347267
    Abstract: A group of cabinets or other units each have a solenoid operated lock controlled by an electronic lock accessible by one or more electronic keys. The locks are linked together in a chain by power and data lines so that power is supplied through a single 12 volt transformer, and key codes are transmitted from a lock that reads a key to other locks, to open any cabinet programmed with an access code matching the transmitted key code. To limit power requirements, when one solenoid is being energized a busy signal is transmitted to prevent concurrent operation of other solenoids. A user installed master code stored in the lock and a corresponding master key are used to permit programming or erasing of other access key codes. A factory installed permanent reset code is stored in the lock and a secret algorithm known only to the manufacturer can derive the reset code from the cabinet serial number.

  • Patent number: 5343766
    Abstract: A micromachined accelerometer includes two capacitors comprising a pair of fixed capacitor electrodes and an intermediate movable proof mass serving as a common electrode which is displaced under acceleration to differentially vary the capacitances. A circuit holds the common electrode at a bias voltage and a switching circuit rapidly alternating between two phases separately connects the fixed electrodes to a main reference voltage and to ground during a first phase and to a common intermediate voltage during a second phase. A charge amplifier senses capacitance changes due to acceleration to produce an output voltage and an attenuating amplifier responsive to the output voltage produces the common intermediate voltage. A compensation servo circuit responsive to the output voltage generates the bias voltage which controls an electrostatic balancing force which is applied to the proof mass during the first phase to maintain the proof mass near a rest position.

  • Patent number: 5343351
    Abstract: A starter motor energized through a relay is protected from low voltages by a circuit which senses low voltages and turns off the motor relay via a transistor switch. A generator voltage sensing circuit also turns off the relay via the same switch when a generator voltage threshold is reached. For operation over a wide system voltage range, the coil of the relay is protected against high voltages by a chopper circuit which operates the transistor switch at a duty cycle of 100% at low voltages across the coil and lower duty cycles at high voltages. For a 12 volt relay the average current at higher voltages is maintained at a value approximating that obtained at a steady state 12 volts.

  • Patent number: 5341204
    Abstract: Method and apparatus for analyzing the deformation of an object resulting from the application of stress. A novel optical element is used to perform shearometric analysis upon a test object. The novel optical element has an overall pattern of first and second pluralities of regions having significantly different indices of transmissivity. The pattern of variations causes pairs of light rays which are reflected from two distinct points on the test object at a divergent angle to emerge from the optical element so that they are nearly parallel. The nearly parallel rays are then received upon a photoelectrical sensing means such as a video camera or photoelectric array. Because the rays impinging thereon are nearly parallel, they may be adequately resolved by the photoelectric sensing means, thus enabling shearometric analysis to be performed electronically in a rapid and cost-effective manner.
