  • Patent number: 5448303
    Abstract: An apparatus and method for generating a modified video signal consisting of a correction signal and a video input signal. The correction signal is derived from a digitized video input signal by at least a frequency-band limiter and an amplitude limiter. The video input signal is delayed by the processing time of the correction signal before the two signals are combined. To avoid unwanted harmonics the amplitude limiter uses a transfer function which can be exactly described by a rational integral function of the nth degree,y=a.sub.0 +a.sub.1 *x+a.sub.2 *x.sup.2 +a.sub.3 *x.sup.3 . . . a.sub.n *x.sup.nwith 1<n<f.sub.n /f.sub.s, where f.sub.n is the Nyquist frequency, f.sub.s is the maximum frequency of the frequency-band-limited video signal, x is the input to the amplitude limiter a.sub.0 to a.sub.n are scale factors, and y is the output of the amplitude limiter.

  • Patent number: 5446852
    Abstract: A method utilizing a predetermined set of instructions in a wait routine reduces spurious signals caused by the power consumption of processors, particularly digital signal processors, which is dependent on the instruction code being executed. These spurious signals occur, for example, in processors performing cyclically recurring program routines which are initiated by interrupts where, during the run time of the routines, a first mean power consumption results, and where the run time of the program routines is shorter than the time between two successive interrupts. The cyclic changes in power consumption caused by this mode of operation of the digital signal processor are avoided by performing a wait routine between successive program routines which includes instructions selected to cause a mean power consumption of the processor during the wait routine to correspond to that during the program routines.

  • Patent number: 5443083
    Abstract: The valving element is positively tied to a pressure-sensing and -responsive diaphragm, via a diaphragm-carried insert. The connection is so arranged as to permit relative angular displacement, between the valving element and the diaphragm, so that cocking of the element, in its axial movement, will not occur. The gas filter is formed of a sintered plastic to avoid corrosion and flaking off of metallic particles. An aspirator hole communicates the diaphragm with the low-pressure chamber outlet, but has an artificially lower pressure, than the outlet pressure, introduced to the diaphragm, through the use of an ejector nozzle. A hole formed in the bonnet establishes atmospheric pressure above the diaphragm, but a porous plug in the hole prevents any ingestion of water, from puddle-splashing, take up from wet roads, and the like.

  • Patent number: 5444568
    Abstract: A night vision goggle device is fabricated for consumer use. The device employs interpupillary and diopter adjustments for each eye of the user. The combined adjustment mechanism incorporates manually operable control knobs located on the housing and one knob for each of the eye pieces. Each control knob is capable of moving both in a forward and rear mode and in a transverse mode. The knob can provide diopter focus adjustment for a front to back motion and for lateral movement or transverse movement the control provides for interpupillary adjustment. The movement of the knob and the removal of pressure or force from the knob enables the optical assemblies to be locked in position by a friction fit.

  • Patent number: 5443309
    Abstract: A solenoid valve which has a valve-dome-enclosed armature which, in dependence on a current energized magnet coil arranged on the valve dome, performs a stroke motion, so that a valve tappet movable with the armature and partially surrounded by a magnet core acts on a valve seat in a valve housing. For the purpose of damping valve operating noises that possibly might form, at least one recess of defined length, width and depth is arranged on a circumferential surface of the valve tappet which is remote from the armature, with the recess partially extending in the longitudinal direction.

  • Patent number: 5444507
    Abstract: An apparatus and associated method of joining a night vision device to a camera device to record images during night time or low light conditions. The present invention includes a substantially rigid mounting plate that connects to the bottom surfaces of both the night vision device and the camera device, whereby the objective lens assembly of the camera device is held in optical alignment with the ocular lens assembly of the night vision device. As a result, the night vision device and camera device are joined together both physically and optically, while each is also independently supported by the mounting plate. The mounting plate is configured to compensate for size differentials between the night vision device and the camera device. Accordingly, the mounting plate aligns the optical axis of the night vision device with the optical axis of the camera device even if these optical axes normally do not align.

  • Patent number: 5443133
    Abstract: The invention is related to a brake shoe with a chamfered edge lining, the chamfered edge achieving desired surface configuration of the lining after only a few braking actions while increasing the service life of the lining. The chamfer has a profile shape which features a hyperbolic contour, steeply angled at the top adjacent the outer face and very shallowly angled at the bottom adjacent the backing plate so that the increment of wear of each braking operation decreases in a strongly degressive way.

  • Patent number: 5441317
    Abstract: A superlock assembly includes a motor having a pinion mounted on its output shaft and meshed to an output gear. A blocking arm is secured to the output gear. To engage the superlock assembly when the arm of the locking actuator is extended, the motor is powered to move the blocking arm into the path of the retractable arm. In this position, the arm cannot be retracted either through manual force or electric operation of the actuator, thereby preventing a door latch from being unlocked.

  • Patent number: 5435750
    Abstract: A boardlock is provided to hold a connector flange (20, FIG. 2) above a circuit board (14), which securely holds the flange in position. The boardlock (30) includes a body (40) with an upper portion (42) mounted on the connector flange and a lower end (44) lying above the circuit board. A pair of beams (50, 52) extend down from the body lower end to project through a circuit board hole (54) and engage a lower surface of the circuit board. A pair of standoffs (80, 82) extend down from the body lower end and abut the upper face of the circuit board. While the beam upper parts (74) can bend, the standoffs are rigid against bending and are horizontally spaced from the upper parts of the beams. A boardlock designed for machining, has beams and standoffs that are part of a form of circular shape but with a wide slot (98, FIG. 4 ) separating the form into separate beams and standoffs.

  • Patent number: 5435664
    Abstract: The tank has vertical walls joined to a horizontal bottom with a diagonal wall bridging between an intermediate portion of one of the vertical walls and the bottom. The diagonal wall has an access opening formed therein, and it cooperates with the one vertical wall and the bottom to form a sheltering recess, in the tank, for pumping station components. The pumping station has the relevant components emplaced in the tank, and sewage water admitting and discharging facility, with a submersible pump and water-handling piping. Station components, and portions thereof, are sheltered in the recess of the tank, to accommodate an optimum water flow in the tank, and to minimize an entanglement of solid objects with the components.

  • Patent number: 5432442
    Abstract: An air gap detector for use in antilocking brake systems includes an active integrator that integrates an output signal from a wheel speed sensor, that depends in part on the relative spacing between the wheel axle and its associated bearing, to thereby produce a signal that is inversely proportional to the air gap between the axle and bearing. The integrated signal is processed by peak detecting means to produce a peak signal that is proportional to the size of the air gap. The peak signal is then amplified and adjusted to produce a D.C. signal that is proportional to the size of the air gap.
