Abstract: A hard drive particle cleaning system includes an air source, an ionizer module coupled to the air source via upstream tubing, a mechanical shock system configured to secure a hard drive and apply a mechanical shock to the hard drive to dislodge particles inside the hard drive, and an exhaust system. The ionizer module includes a shell and an inlet nozzle arranged in a first end of the shell and coupled to the upstream tubing for supplying a stream of air from the air source into the shell.

Abstract: Disclosed is a system and method to monitor and count particles removed from a component. The particle monitoring system includes a jet spray device, a snow generator, a particle collection device, and a particle counter. The jet spray device includes an outlet that is disposed locally relative to the component. The snow generator is operable to generate cleaning snow comprising a stream of ice particles, wherein the cleaning snow is emitted from the outlet of the jet spray device onto the component to cause the ejection of particles from the component. The particle collection device includes a collector that is disposed locally around the component to collect particles ejected from the component. The particle counter is coupled to, and in fluid communication with, the particle collection device. The particle counter is operable to detect and count particles ejected from the component.

Abstract: A device for locking skis in a crossed relationship. A pair of elongated, flat ski engageable members are hinged together at adjacent ends for relative movement into and out of operative positions in which the members are longitudinally aligned with each other. A central triangular wedge is mounted rigidly to one of the flat members. An inwardly facing U-shaped channel at the outer end of each of the flat members receives one side edge margin of a respective ski. The other side edge margin of the ski engages and is held against the adjacent side face of the central triangular wedge. A lock plate carried by the triangular wedge is movable into overlapping relationship to the side faces of the wedge to form channels near the zone of hinging to capture the other side edge margins of the ski to thereby secure the skis to the device. The members can be moved out of their operative positions and into side-by-side relationship to make the device sufficiently compact to fit easily into a garment pocket.
