Appl. No.:

09/811310

International Classification:

G02B 6/00

US Classification:

385135

Abstract:

A device for storing and deploying cable, including but not limited to optical fiber cable. The device includes a substantially planar bottom support surface having juxtaposed thumb segments and an intervening finger segment. An outer wall is affixed to the bottom surface about its perimeter and extends upwardly therefrom. A substantially circular guide wall is disposed on the bottom surface extending upwardly therefrom. A substantially circular inner wall is concentrically arranged with respect to the guide wall. A top flange is joined to the support surface by the outer wall and, together with the thumb segments, form entry and exit ports for the cable. The guide wall and the inner wall define a guide track that is dimensioned so as to enable continuous adjustment of variable lengths of cable in an area of the device bounded by the guide track, the outer wall and a transverse barrier that extends the length of the finger segment. The guide track operates to secure the cable in the device once an appropriate length has been accumulated or deployed.

International Classification:

G09G 5/08

US Classification:

345166, 345163, 345164, 345165, 345167

Abstract:

An optical tracking assembly for an optical mouse includes a light source, an optical sensor chip, and an integral optics assembly. The integral optics assembly includes lenses and alignment features receiving the light source. The alignment features center the light source to the lenses and control a distance the light source is placed away from a navigation surface that reflects light onto the optical sensor chip. The lenses may include (1) collimating lenses for collimating light from the light source along a first optical axis to the navigation surface, and (2) imaging lenses for imaging reflected light from the navigation surface along a second optical axis to the optical sensor chip.

International Classification:

G09G 5/08

US Classification:

345163, 345156

Abstract:

A contaminant-neutralizing cradle comprises a base and a support surface configured to removably receive a coherently-illuminated mouse. A neutralizing element is disposed on the support surface for alignment with at least one exposed surface of an optics module of the mouse and is configured to neutralize the optical effect of a contaminant on the at least one exposed surface. A method of neutralizing contaminants for an optical mouse comprises providing a mouse containing an optics module having at least one surface exposed to an opening of the mouse and interposing a barrier in the mouse between a contaminant and the at least one exposed surface. A method of detecting contaminants comprises aligning an optics module of a mouse with an imaging surface, obtaining a first image of the imaging surface, via application of coherent illumination from the optics module to the imaging surface, analyzing the first image to identify an interference pattern associated with a contaminant, alerting a user if a parameter of the interference pattern exceeds a threshold value.

Inventors:

Paul D. Welch - Milpitas CA

Assignee:

Sun Microsystems, Inc. - Mountain View CA

International Classification:

A47G 1908

US Classification:

211 4117

Abstract:

During processing, such as wave soldering, it is necessary to support a printed circuit board (PCB) above a pallet or carrier without sagging. A support rod has hooks which fit through holes in the PCB and engage the margins of the holes. Ends of the rod are provided with second hooks which engage the pallet or carrier to support the rod above the pallet and thereby support the PCB. Preferably the rod is multi-sectional and spring biased so that the hooks may be conveniently installed in the holes.
