Abstract: A lighting device is provided for attachment to a component that defines an open area. The lighting device includes a mounting plate and a light emitting diode (LED) assembly. The mounting plate extends longitudinally, and is disposable within the open area. The mounting plate presents a first mounting surface and a second mounting surface. The LED assembly is operatively attached to the first mounting surface, with the LEDs being operatively attached to the first mounting surface, such that the LEDS form at least two columns. Each LED is configured to emit a respective field of light in response to being energized. The LED assembly is configured such that a field of light projected from the LEDs for one of the at least two columns is projected radially away from the field of light projected from the LEDs for the other of the at least two columns.

Abstract: A conveyor assembly is provided for movably supporting a tire of a vehicle. The conveyor assembly includes a track, a dolly, and a trapdoor assembly. The track is configured for supporting the tire of the vehicle. The track terminates at an edge, and a gap is defined beyond the edge. The dolly is configured to move along the track to the edge so as to guide the tire along the track to the edge. The trapdoor assembly is configured to substantially cover the gap when in a closed position and is movable to an open position to uncover the gap and allow the dolly to translate around the edge. The trapdoor assembly includes a device configured to prevent a human from inadvertently opening the trapdoor assembly.

Abstract: An axially expanding spacer (10) has respective first and second spacer rings (11,12) with complementary helical ramped faces (16,17) and abutment faces (18,19). By relative rotation of the spacer rings (11,12), the height of the spacer (10), between annular faces (14,15) can be expanded or contracted. Compression springs (20) between the abutment faces (18,19) urge the spacer (10) to its “expanded” configuration.

Abstract: A heated towel dispenser includes a roll of a semi-absorptive medium that can be readily separated into individual sheets. The dispenser includes one or more different fluids to be applied to each of the sheets as directed by a user. The dispenser includes a heating element therein to heat each of the sheets prior to them being emitted from the dispenser. A plurality of sensors are disposed in the dispenser to monitor conditions within the dispenser.

Abstract: A rotary finishing device including a generally circular hub having an inner periphery and an outer periphery. The outer periphery includes a plurality of slots formed thereabout, which are defined by a pair of side portions. The plurality of slots are generally uniformly spaced about the outer periphery of the hub. Each of the slots has at least one finishing sheet secured therein by an adhesive.

Abstract: A method, system, and storage medium for implementing intelligent team management services. The method includes associating selected individuals with a datastore. The datastore houses content designated as key information and the selected individuals are designated as an entity. The method also includes creating a distribution list in a messaging application. The distribution list includes the selected individuals. The method further includes providing the selected individuals with access to the datastore.

Abstract: A rotary finishing device includes a generally circular hub having a front surface, a back surface, an inner periphery and an outer periphery. The inner periphery of the device defines a throughhole. The front surface of the hub has a plurality of slots formed therein. Each of the plurality of slots has a plurality of finishing sheets secured therein by an adhesive. Each of the finishing sheets is of sufficient length such that when the generally circular hub rotates at a slower speed, the plurality of sheets remain within the outer periphery of the generally circular hub and provide a relatively flexible device for contacting a surface to be finished. Further, when the generally circular hub rotates at a higher speed, the plurality of sheets extend beyond the outer periphery of the generally circular hub and provide a relatively stiff device for contacting a surface to be finished.

Abstract: An active cancellation device receives a model of a first signal from a local wireless transmitter. The first signal causes a coupled signal that interferes in a second signal received by a local wireless receiver from a remote wireless transmitter. The active cancellation device generates a cancellation signal based on the model of the first signal, and provides the cancellation signal to the local wireless receiver. At the local wireless receiver, the cancellation signal combines with the coupled signal and the second signal. The cancellation signal reduces the interference in the second signal caused by the coupled signal.

Abstract: A vehicle, such as a mini-van, is modified to include a vehicle kneel pump system and a ramp pump system. The kneel pump system lowers the rear end of the vehicle. The ramp pump system controls a rearwardly folding ramp to enable entrance and egress from the vehicle of a wheelchair bound person. A loading control system integrated into the vehicle includes a loading controller which controls the ramp pump system and the vehicle kneel pump system. In response to pushing a button of a remote controller, a powered door operating system controls the door. In response to signals received from the door operating system, the loading controller controls the kneel pump system and the ramp.

Abstract: In an automobile conveyor having an endless conveyor chain within a framework having top plates to support the tire of an automobile, and a plurality of roller dollies spaced along the length of the chain normally positioned for movement within the framework, the improvement which comprises a split collar clamp having first and second sections that are clamped around the driven shaft of the conveyor. The first section of each clamp is angled with respect to the vertical so that the shaft is cradled against the pulling force of the drive sprocket. The second section of the clamp is removably attached to the first section so that the clamp is accessible from the top plate of the conveyor for easy access and removal of the driven sprocket, bearing members and transverse sprocket shaft through the top plate.

Abstract: An automobile conveyor having an endless conveyor chain within a framework having top plates to support the tire of an automobile and a plurality of roller dollies spaced along the length of the chain normally positioned for movement within the framework. Each of the roller dollies includes at least one upright mounting plate connected to the conveyor chain. The plate supports three equally spaced rollers which substantially form an equilateral triangle with one roller forming the vertex of the triangle and the other two rollers being coplanar forming the base of the triangle. The one roller is adapted to operatively engage to automobile tire with the other two rollers adapted for supported movement upon the top plates.

Abstract: A power operated elevator ramp for use in an automobile conveyor having an endless conveyor chain within a framework having top plates to support the tire of an automobile and a plurality of roller dollies spaced along the length of the chain normally positioned for movement within the framework, the ramp having a solenoid controlled valve, air cylinder assembly and related linkage mechanism, for selectively deflecting a dolly onto the top plates for movement thereover and for advancing the vehicle tire thereon. An elongated flexible belting overlies the framework throughout its length and protectively covers the top plates, roller dollies and conveyor chain and provides a protective cover for personnel. A deflected roller dolly forms a transverse wave in the belting for operative pushing engagement with the vehicle tire.
