  • Patent number: 6185303
    Abstract: An enclosure mounting bracket kit for attaching an enclosure with an exterior flange to a post is described. The mounting bracket includes an elongated horizontal rigid bar having first and second elongated studs protruding from the front side surface for penetrating the mounting holes of the flange; at least one through-hole in each of the first and second studs transverse to a long axis of the stud so that when each of the first and second studs penetrates a mounting hole the through-hole penetrates the flange; first and second releasable pins for positioning in each through-hole and gripping each of the first and second studs respectively; a block attached to the rear side surface of the bar between the first and second studs, the block having a surface generally conforming to the outside surface of the post; an adjustable strap attached to the rear surface for encompassing the post; and a ratchet tensioning device pivotally attached to the rear surface for tightening the strap around the post.

  • Patent number: 6054951
    Abstract: A multi-dimensional tracking sensor for tracking a moving transmitter with particular applications in virtual reality and other real time computer applications. The system employs an electro-magnetic (EM) tracking sensor having a small lightweight transmitter with a transmitting antenna located on the target to be tracked and an array receiver with several local stationary antenna elements. Multiple antenna elements of the array receiver lie on the perimeter of the measured space in positions determined by a self-calibration procedure. The proposed device calculates a cross correlation function between two signals at each receiving unit to determine a spatial position of the tracked element via a system of linear equations.

  • Patent number: 6036349
    Abstract: Predictive models have always been sought in the physical, biological and social sciences, but the application of such models may not produce reliable results. Before accepting a prediction from any model, it is essential to ascertain that the model is applicable to make the prediction. The present invention generally relates to a method for validating a model based prediction and more specifically, to a method for validating whether selected models are applicable to selected queries and comparing the performance of the predictive model on a query object or point, etc., with the performance of the predictive model on an existing object having a shortest property sensitive similarity index from the query object or point, etc. in a data processing system.

  • Patent number: 5956173
    Abstract: Our invention achieves spectral broadening of an input pulse by propagating it through a hollow fiber filled with a noble gas. The output pulse is then compressed to a shorter duration by passing it through an optical system consisting of phase dispersive elements. In a preferred embodiment, the input pulse is generated by a mode-locked laser, amplified and then subsequently compressed to produce an input pulse of high peak power. This input pulse is then focused into a hollow cylindrical fiber made of fused silica and mounted inside a pressure vessel filled with noble gas. The optics are designed to match the spatial mode volume of the input pulse to that of the entrance aperture of the hollow fiber. Light is constrained to propagate down the hollow fiber and generates additional bandwidth through self-phase modulation as it interacts with the gas contained therein. The spectrum of the pulse after propagation through the gas is frequency chirped.

  • Patent number: 5952593
    Abstract: A fretted stringed musical instrument is provided with channels which can removably accommodate frets. In a preferred embodiment of the invention, the channels are provided at locations where it is sometimes, but not always, desirable to have a fret. The frets which are standard to the instrument may remain imbedded in the fingerboard. Alternatively, channels may be provided at all possible fret locations such that the instrument can be played fretted or unfretted. This embodiment would eliminate the need for expensive, time consuming, and instrument damaging refretting operations. In another embodiment of the invention, a set of tempered frets can be used to change the temperament of the instrument, such as from equal temperament to mean temperament in an Appalachian dulcimer. In another embodiment, using frets having a variety of lengths, it also becomes possible to fret only certain strings.

  • Patent number: 5947490
    Abstract: A seat assembly for a pedestrian operated machine may be pivotally attached to the rear of the machine at (22) and comprise a frame (20) having a spine (30) with a spine extension (31) supporting a seat (32) on a stalk (34) supported by a wheel (26). The spine extension is movable between a retracted pedestrian operated mode and an extended ride-on mode when the seat can be pivoted from a fold-away position to a position of use. When in its extended position the spine extension allows the frame to be pivoted about a vertical axis (40).

  • Patent number: 5923418
    Abstract: An apparatus for maintaining an electromagnetic beam, namely a laser beam, aimed at a particular point in space and aligned with a unique propagation path. The apparatus includes one or more adjustable beam steerers located in the propagation path, and first and second spaced apart beam position detectors arranged in the beam path. The beam steerer(s) are preferably adjustable along at least two orthogonal axes of rotation for controlling the propagation direction of the beam. Error signals from the position sensors are fed into a beam steerer controller connected to the beam steerer(s) for electro-mechanically adjusting the beam steerer. The method of the invention involves fixing the propagation path on an angularly adjustable beam steering surface so that the propagation path at a different unique point in space, such as a target, can be controlled by adjusting the angular orientation of that beam steerer.

  • Patent number: 5907984
    Abstract: A method and apparatus for cutting sheet material upon an apertured support surface, the apparatus including a pair of spaced apart parallel cutters. The cutters are spaced apart by a distance greater than a dimension of the apertures, but less than an inter aperture distance so that at least one of the cutters remains in cutting contact with the support surface when the remaining cutter passes over an aperture. The method includes selectively overcutting and undercutting the line segments at an intersection to ensure continuity of cut paths of both cutters.

  • Patent number: 5901657
    Abstract: A support structure for a flexible boat cover includes an extensible bar supported entirely by at least one cord extending therefrom to cleats located at the bow and stern of the boat. This invention provides multiple supports spaced laterally from the centerline of the boat without any additional hardware. The cord preferably elastic, may extend over the top of the windshield to provide an inclined support structure to prevent collection of water in the boat cover. The bar is extensible to accommodate boats of various widths and to reduce its length for storage when not in use. Additionally, the bar can be supported by posts underneath to support ice and snow in colder climates during the winter.

  • Patent number: 5898977
    Abstract: A supporting bracket for windows which can be used on any side of a window and which can be mounted using existing central mount installation tooling is disclosed. The supporting bracket uses dual sided containment of the vent bar end for preventing sash play and uses camming surfaces to allow for immediate sash pull in which prevents weather-strip problems and prevents the supporting bracket from binding during an opening operation. In some embodiments, an end cap engages opposite sides of a symmetric vent bar end. In another embodiment, a pin attached to the vent bar is engaged on opposite sides by a track formed within the main track of the supporting bracket. In all embodiments, the vent bar and the link pivotally connecting the vent bar to the track are prevented from moving in a direction opposite the direction of opening during an opening operation. The arms of the supporting bracket may have fully rounded edges for preventing binding between adjacent arms during load.
