Abstract: A laser system for processing conductive link structures includes a seed laser generating a seed laser beam. The seed laser is sliced by a modulator into a user configurable series of pulses and the pulses are optically amplified and applied to a conductive link structure. Preferably, the bandwidth of the seed laser is less than 1 nm with an IR center frequency, and the frequency of the laser light of the pulses is doubled or quadrupled prior to application to the conductive structure. Preferably, the pulses are about 1-18 nanosecond pulsewidth and are separated by 100-400 nanoseconds.

Abstract: A laser processing system includes a first positioning system for imparting first relative movement of a beam path along a beam trajectory with respect to a workpiece, a processor for determining a second relative movement of the beam path along a plurality of dither rows, a second positioning system for imparting the second relative movement, and a laser source for emitting laser beam pulses. The system may compensate for changes in processing velocity to maintain dither rows at a predetermined angle. For example, the dither rows may remain perpendicular to the beam trajectory regardless of processing velocity. The processing velocity may be adjusted to process for an integral number of dither rows to complete a trench. A number of dither points in each row may be selected based on a width of the trench. Fluence may be normalized by adjusting for changes to processing velocity and trench width.

Abstract: A drag reducing device includes an air flow turning component having a curved surface adapted to turn air flow passing over the curved surface, a first mounting component for connecting the air flow turning component to a rear door of the vehicle, and a second mounting component for connecting the air flow turning component to one of the opposite side walls of the vehicle. The mounting components are configured so that the air flow component is automatically in a deployed position when the rear door is closed, so the air flow turning component turns air flow passing along the side the vehicle inward to thereby reduce drag. The mounting components are further configured so that the air flow component is automatically stowed between the rear door and the vehicle side wall when the door is fully opened. The air turning component is sized for a minimal prominence when stowed.

Abstract: Braking current generated by an electrical motor on mining equipment during a retard interval is switched through one or more grid resistors that are liquid cooled. Under low ambient temperatures, a heating current can be switched through the grid resistors when the electrical motor is not operating in a retard interval. An integrated cooling system can be used to cool grid resistors and power modules. Heat dissipated by the grid resistors and the power modules can be circulated through auxiliary heating loops to heat portions of the mining equipment under low ambient temperatures. Multiple liquid-cooled power modules, liquid-cooled grid resistors, auxiliary heating loops, control modules, radiators, and pumps can be coupled by a liquid distribution system with various combinations of parallel and serial branches. Temperature, pressure, and flow rate in each branch can be independently controlled. Operation of the integrated cooling system can be controlled by a computational system.

Abstract: A strut clip for facilitating attachment of pipe hangers, electrical conduit, or other structures to open channel unistruts. The strut clip includes an assembly of a face element and a nut element. The face element includes a centrally located threaded aperture, a face element rear surface, and a pair of flanges extending rearwardly from the face element rear surface. The nut element includes a nut element rear surface, an unthreaded aperture for free passage of a fastener, and a pair of openings therein. The flanges of the face element extend through the openings in the nut element thereby forming the strut clip assembly. Nut element further includes a narrow side, a wide side, and beveled edges that enable attachment to a unistrut by simply inserting the narrow side of the nut portion into the open channel of the unistrut and rotating the assembly by 90 degrees.

Abstract: A hygiene compliance module is configured to be retrofit with a compatible dispenser to enable hygiene compliance monitoring functions. The hygiene compliance module is configured to be coupled to the dispenser via a communication interface to receive power, ground, and dispenser actuation signals therefrom. In addition, the hygiene compliance module is enabled to communicate with a wireless data tag that is worn by a user of the dispenser and with a remote hygiene compliance monitoring station.

Abstract: A storage tote includes a base and a selectively movable lid. A support assembly is secured to the base and movable between a folded position and a deployed position. In the folded position, the support assembly extends generally parallel to the surface upon which it is supported. In the deployed position, the support assembly extends generally downwardly to support the base at a height substantially above the support surface. The support assembly may include a pair of opposing legs. The support assembly may additionally include a one or more pairs of wheels for selective movement of the storage tote from one location to another. A leg retention assembly may be provided for securing the legs in the folded position to prevent accidental or otherwise unwanted movement of the legs from the folded position.

Abstract: A sighting device replicates the spread pattern of pellets exiting the barrel of a shotgun. The sighting device includes a light source (preferably a laser) and a power source connectable to the light source. The device may also include a mount to attach the sighting device to a shotgun. The sighting device preferably projects a circular pattern of individual light beams wherein the circumference of the circular pattern increases as the light beams move farther from the sighting device to replicate the spread of shotgun pellets. The sighting device may also project a beam of light in the center of the pattern.

Abstract: A dispenser housing has a closure mechanism that serves to hold the dispenser housing closed. A key either can be carried by an individual to be employed to override the closure mechanism to permit the opening of the dispenser or can be selectively mounted to the dispenser housing to position a release mechanism appropriately to permit the release mechanism to be manipulated to override the closure mechanism. When the key is not mounted to the dispenser, the release mechanism cannot be appropriately manipulated to override the closure mechanism.
