  • Publication number: 20040206530
    Abstract: A vented riser assembly, having a vented riser incorporated into a main riser, to protect and passively cool power conductors housed therein. The riser assembly is vertically attached to an utility pole and operates in chimney-like fashion to cool warmer air within the main riser, that had become heated due to electrical resistance in the power conductor, by drawing cooler ambient air through apertures in the vented riser while passively exhausting warmer air through the top of the main riser. The affect of reducing temperature within the riser system is to increase amperage, which is adversely affected by an increase in temperature.

  • Patent number: 6330361
    Abstract: An improved optical correlator using a coherent light beam employs a method of adaptive alignment. A test pattern modulates an input spatial light modulator. The modulated beam propagates through passive transforming optical elements to a filter spatial light modulator, which is simultaneously modulated with an independently transformed frequency domain reference. The resulting correlation or coincidence of the optically transformed pattern with the independently transformed reference is processed to yield a feedback signal indicative of any optical misalignment of the optical correlator. The feedback signal drives a beam deflector to compensate by adjusting the path of the coherent beam, thereby improving and maintaining optical alignment of the correlator.

The rails are elongated generally U-shaped members which include an intermediate semicircular portion extending outwardly and having a spring loaded lock pin mounted therein to engage the scaffold through an aperture in the rail locking the table in place. A second pair of U-shaped elongated rails extend outwardly at a right angle to the first pair of rails beneath the ends of the table and a supporting member extends between the lower portion of the first pair of rails and an intermediate portion of the second pair of rails for support purposes. A drawer may be mounted at the open end beneath the table.

  • Patent number: 5786895
    Abstract: Based upon the equation, BIAS.sub.G .alpha. (I.sub.DE -I.sub.COIL).multidot.(V.sub.DE -V.sub.OFF), where BIAS.sub.G is the bias of a multi-oscillator ring-laser gyroscope (14) as induced by gain medium dispersion effects, I.sub.DE is the proper operating coil current, I.sub.COIL is the actual coil current, V.sub.DE is the proper path length control operating voltage and V.sub.OFF is the actual offset voltage, V.sub.DE is matched by path length control offset voltage and/or I.sub.DE is matched by proper coil current, to produce a zero induced BIAS.sub.G. Matching, through dispersion equalization (DE), is effected by use of clockwise (C) and anticlockwise (A) (or counterclockwise) beams traversing paths with a frame (12). The beams are directed to photodetectors (52, 54) and power meters (56, 58).

  • Patent number: 5488622
    Abstract: At least one coil (32) is located on an exterior side face (30) of a frame (12) of a ring laser gyroscope (10) such that a significant component of the magnetic field generated by the coil is colinear with the plasma discharge of the gyroscope, and by which dispersion equalization of the gyroscope can be effected. The coil may be supported by a magnetically permeable annular bobbin (40), which is set about a mirror (26) on side face (30) and which may be partly set within grooves in the side face, to reduce the current necessary to effect dispersion equalization and to provide shielding of the mirror from the effects of tangential and transverse fields, and to increase the shielding effects for the mirror, both from Faraday rotator magnets (16) and from external magnetic fields. For those mirrors where no coils are present, the annular bobbins are used solely for their shielding properties.

  • Patent number: 5116132
    Abstract: A ring laser gyroscope output optics detection system, including a rotational sensing system and cavity length control system for a multioscillator ring laser gyroscope, is disclosed herein that can operate with a simple upright symmetric optics mechanism, where the required signal separation is performed fully electronically. In a preferred embodiment, signal separation circuitry is provided which performs a 90.degree. or .pi./2 radians phase shift to one of a set of heterodyned signals in order to extract the sagnac effect modulated Faraday frequency signals W.sub.A and W.sub.B. In order to deal with the inherent problems of crosstalk present in a Faraday biased system, alternative signal separation schemes suggest the use of a 45.degree. or .pi./4 radians phase shift, as well as a 60.degree. or .pi./3 radians phase shift. Complementary cavity length control schemes are presented in both fixed component and digitally controlled formats.
