  • Patent number: 6364043
    Abstract: A locking mechanism limits the motion of a vehicle cab that swings down on the vehicle chassis to rest on a floating bracket, where the floating bracket is supported by shock absorbers mounted to a chassis. The mechanism prevents upward movement of the floating bracket and thereby prevents upward swing of the cab from the chassis. The locking mechanism includes a flat arm fixed to the floating bracket and a fulcrum member fixed to the flat arm. The fulcrum member pivotally mounts a swing arm having a projection at one end. The mechanism is in a locking condition when the projection engages a mounting bracket fixed to the chassis. At different times when the cab swings down to the floating bracket, the cab's alignment with the chassis varies. The locking mechanism has features which allow it to adjust three-dimensionally to variations in this alignment.

  • Patent number: 6290313
    Abstract: An improved track end connector for a double-pin track assembly of a tracked vehicle includes a novel connector body, a bolt in the connector body, track pins held by the bolt, and a retainer ring engaging both the body and the bolt. The connector body defines a smooth bore having a relief groove holding the retainer ring. The bolt is inserted through the smooth bore until threads at one end of the bolt engage a second, threaded bore in the connector body. As the bolt screws into the threaded bore, a ramp near the bolt's head expands the retainer ring. As the bolt screws further into the threaded bore, a retention groove on the bolt is clinched by the retainer ring, so that the bolt can not unscrew from the threaded bore. A smooth shank portion of the bolt seats with concave depressions in the track pins, so that the track pins do not escape from the connector body.

  • Patent number: 6257340
    Abstract: A rapidly actuating fire extinguishing system incorporates a shock tube construction. The system includes first and second shock-tube sections joined by flanges and sealed from one another by a diaphragm. The first shock tube section contains either fluid under high pressure, or a gas generator or an arc vaporization mechanism. The second shock tube section contains a volatile fluid extinguishant. When the system actuates, the diaphragm is ruptured, so that pressure in the first shock tube section initiates a shock wave that propagates through the extinguishant in the second shock tube section. The shock wave energizes the extinguishant so that it becomes highly pressurized and ruptures a second diaphragm, which is disposed between the second shock tube section and a conduit. The extinguishant then travels along the conduit to a spray head from which the extinguishant is dispersed.

  • Patent number: 6164736
    Abstract: A shock absorbing, tracked wheel assembly of an off-road vehicle has a set f spoke-like structures radiating from the assembly's center or spider. The spoke-like structures include cylinders affixed to the spider and pistons axially translatable in the cylinders. The pistons are biased radially outward by coil springs in the cylinders. The springs' action is dampened by a flow restrictive collar girding the piston and separating fluid in the cylinder into separate chambers. Struts extend from the pistons and the struts have track engagement shoes on their outer ends. The shoes have a generally arcuate sector that engages a track or band in tractive contact with the ground. Rotating the struts about their longitudinal axis will vary the distance between the cylinder and the track shoe so that tension on the track can be adjusted. Sufficient strut rotation allows the track to be removed from the assembly for purposes of track repair or replacement.

  • Patent number: 6100923
    Abstract: The method herein images an object repeatedly moving about an axis. The mod uses signals to track the object's position with respect to the axis while a camera views the object. A reflection is cast from the object toward the camera in such a way that the camera scans both the reflection and the object. The camera outputs representations of video lines, which depict parts of the object and the reflection. These video lines have known positions relative to a reference plane, which passes through the image plane of the camera. Certain of the video lines are selected. The selected lines come from a chosen position relative to the reference plane and occur within a chosen time of the position signals. The selected video lines are arrayed according to their particular position signals and are used to compile a planar composite image representing the object's outer periphery. The composite image is conformed to a shape resembling the periphery, thereby creating a three dimensional representation of the object.

  • Patent number: 6081753
    Abstract: A method to determine the probability of detection, P(t), of targets within infrared-imaged, pixelated scenes includes dividing the scenes into tar blocks and background blocks. A plurality of .DELTA.T metrics are applied to the blocked scenes to derive various .DELTA.T values for each scene. Factor analysis is then used on the various .DELTA.T values to derive a relative .DELTA.T for each scene. The scenes are divided again, into cells of pixels, in accordance with a plurality of clutter metrics. These clutter metrics are used to derive various clutter values for each scene. Factor analysis is used on the various clutter values to derive relative clutter values for each scene. The relative .DELTA.T values and the relative clutter values are used in determining the probabilities of detection of the targets in the scenes. Based on the probabilities of detection, the optimum scene or set of scenes is selected.
