Abstract: A wearable display apparatus has a support that mounts the display apparatus against the head of a viewer; a ball joint that is fitted within the support and coupled to a clamp that extends from the support; a slide that is translatable within the clamp in a first direction and that holds a display module for forming the display image; and a display coupled to the display module and rotatable in a first arc about a vertical axis that extends in a second direction that is orthogonal to the first direction and further rotatable in a second arc about a horizontal axis that is substantially orthogonal to the vertical axis.

Abstract: A bore sight including a rear casing, a front casing sized to cooperatively engage the rear casing and define a first cavity and a separate second cavity, a laser disposed within the first cavity, and a battery in the second cavity. The bore sight further includes a switch selectively connecting the battery and the laser, an elongate mandrel releasably engaging the rear cavity, the mandrel having a free-end, a tapered seating collar having a through hole sized to receive a length of the mandrel, the seating collar being a separate components from the mandrel and the rear casing, wherein the seating collar can be formed of a different second material than the mandrel and the rear casing; and an adaptor releasably engaging a free end of the mandrel.

Abstract: A pre-charged pneumatic airgun includes a reservoir, a stopper, a barrel and a manually actuated degassing tool. The reservoir contains a volume of compressed fluid and includes a discharge port disposed therein through which the compressed fluid is selectively discharged from the reservoir. The stopper is disposed in the discharge port and is moveable between a normal position sealing the discharge port in an actuated position allowing passage of the compressed air through the discharge port. The stopper is biased to the normal position by a biasing force. The barrel is in fluid communication with the discharge port. When the stopper is disposed in the discharged position, the compressed fluid discharged through the discharge port is further exhausted through the barrel.

Abstract: This hinged adjustable component holder for electronic component cabinets relies on a holster with adjustable brackets for holding a wide variety of types and sizes of gateway devices. The holster is provided with openings on all sides to allow heat venting by a wide variety of types and sizes of gateway devices. It is also hingably connected to the component cabinet in which it is mounted so that it can be easily and simply swung in and out for mounting, adjustment, and repair purposes. Further, the holster is provided with a spacing element connecting its hinge and its body so that ample space for connecting cables is left between the gateway device and the component cabinet. Finally, the holster is firmly held in position when swung into place in the component cabinet, but can be easily detached when opened by simply lifting it off of its hinges.

Abstract: The steering wheel together with other controls of an earth moving vehicle such as a motor grader are mounted on a pedestal which may be selectively tilted for optimum positioning for different operators and to enable a particular operator to sit or stand at his convenience. The pedestal is defined by links pivoted together in a configuration which maintains the steering wheel at a substantially constant inclination and which maintains the other controls at preferred positions relative to the steering wheel and is provided with latch means for locking and releasing the pedestal at a selected inclination with a minimum of effort and diversion of attention. The pedestal and controls are arranged to increase safety by obstructing forward pitching of the operator in the event of abrupt vehicle stoppage while providing for rapid escape from the operator's station at either side of the vehicle. .Iadd.
