A system for determining load capacity for a photovoltaic module includes a clip to position a photovoltaic module surface at a load test position and a load test device proximate to the clip, including a pressure applicator and an actuator, wherein the actuator is capable of moving the pressure applicator toward the load test position.

An insert damper for assembly in a tubular drive shaft of a motor vehicle includes a tubular sleeve, a helically wound, resiliently deformable wiper secured to the sleeve, and a corrugated winding secured to the sleeve. The wiper includes an arcuate bead in the form of an arch that spans mutually spaced supports. The insert damper is sized to fit in the bore of the drive shaft such that the bead frictionally engages the surface of the bore and secures the insert in place within the shaft with a resilient press fit. The bead projects radially outward toward the bore beyond the radially outer surface of the winding.

A moving platform/target system (10) for traveling along a predetermined path. The moving platform/target system (10) includes a track (14) defining a predetermined path and a platform (12) engaging the track (14) for movement along the track (14). The platform (12) includes a housing from which wheels (22) extends from opposite sides thereof and facing parallel to the track (14). A guiding device (26, 28) extends from the housing and engages the track (14), retaining the platform (12) in alignment with the track (14). A power circuit (62, 64, 66, 68, 70) is positioned within the housing and is connected to turn the wheels (22) and impart motion to the platform (12). A sensor (32) senses a position of the platform (12) and pauses the forward motion upon sensing a predetermined position along the track (14). The sensor (32) constantly transmits a position signal which is reflected back towards the sensor (32) upon passing of reflectors (16) positioned along the length of the track (14) wherein movement of the platform (12) is ceased for a predetermined time period upon receipt of a reflected signal. The motion of the platform (12) may also be ceased in the same manner using a second sensor (84) and additional reflectors. Furthermore, the pause time of the platform (12) is adjustable as its speed. Control of the platform's movement may be remotely through a transmitter device (126) and the platform (12) may also house a second motor (122) for moving the platform (12) in a forward, reverse, left and right direction.
