Appl. No.:

09/550781

Inventors:

David D. Bohn - Fort Collins CO 80525

International Classification:

B62K 2508

US Classification:

280276, 280 5513

Abstract:

An electronically controlled anti-dive suspension apparatus for a two-wheeled vehicle includes a suspension system, a sensor, an electronics module, and an actuator. The sensor mounted to the vehicle senses deceleration of the vehicle due to a braking action and produces an input representative thereof. The electronics module mounted to the vehicle and connected to the sensor receives and processes the input from the sensor and produces an output corresponding to a desired predetermined response to the deceleration of the vehicle. The actuator mounted to the vehicle and coupled to the suspension system receives the output from the electronics module and in response thereto causes the suspension system to reduce its amount of contraction and thereby prevent any resulting dive of the front end of the vehicle downward toward the ground.

International Classification:

H01J 4014

US Classification:

250214R, 2502081

Abstract:

An electronic device and method of manufacturing the electronic device are disclosed herein. The electronic device comprises a substrate with at least a first and a second linear optical component mounted thereto. Each of the linear optical components includes a photodetecting portion and an interface portion, wherein the photodetecting portions are electrically connected to the interface portions. The photodetecting portions of the linear optical components are aligned along a first axis. The interface portion of the at least one first linear optical component is offset from the first axis in a first direction. The interface portion of the at least one second linear optical component is offset from the first axis in a second direction, which is different from the first direction. This arrangement of optical components reduces the size of the electronic device, which in turn, reduces the size of any device that incorporates the electronic device.

International Classification:

H01L 2700

US Classification:

2502081, 358473

Abstract:

A position sensing device for determining the position of an object to which the position sensing device is attached is disclosed herein. The position sensing device may comprise a substrate, an actuator and a two-dimensional photosensor array wherein the substrate is attached to the object. The actuator may have a first portion and a second portion wherein the actuator first portion is attached to the substrate and wherein the actuator second portion is movably mounted to the actuator first portion along a first axis. The two-dimensional photosensor array may be attached to the actuator second portion. The position sensing device determines the position of the object by electronically and mechanically tracking distinct features on the surface. The electronic component of the tracking involves determining the position of the distinct features relative to the two-dimensional photosensor array. The mechanical component of the tracking involves moving the two-dimensional photosensor array to track the distinct features.

Abstract:

In general, the present invention provides an efficient and effective means for positioning multiple documents over a scanning surface of a scanner or copier without a users intervention. More specifically, the present invention provides an apparatus and process for allowing a plurality of photographic prints to be moved from a tray to a scanning surface and back to the tray without being damaged. Each document is scanned through a transparent belt that protects the document as it moves through the inventive photofeeder and across an associated surface of a scanner or copier.

International Classification:

G01N 2186

US Classification:

25055929, 250216, 250234

Abstract:

A position sensing device having a single photosensing element is disclosed herein. The position sensing device determines the location of an object to which the position sensing device is attached relative to a surface. The position sensing device has a plurality of light paths that direct light from different area portions of the surface to the single photosensing element. Each area portion of the surface is associated with a light source wherein each light source may be activated individually. A processor illuminates these area portions individually. As the area portions are illuminated, the photosensing element creates image data representative of the image of the area portion being illuminated. The processor analyzes the image data and identifies distinct features in the area portions. As the object is moved relative to the surface, the locations of these distinct features relative to the photosensing element move.

Assignee:

Hewlett-Packard Co. - Palo Alto CA

International Classification:

H01J 314

US Classification:

250234, 2502081

Abstract:

The present invention provides an optics module for a scanning device such as a portable scanner. The optics module includes an illumination source and guide that transmits light through an optical window of the scanning device casing before reflecting off of the object to be scanned. The reflected light from the object travels back through the optical window and a lens before reaching a photosensor for evaluation by an associated microprocessor. The optical window of the scanning device provides a recessed portion in the scanning device casing. The recessed portion of the window is formed using the functional components of the optics module to eliminate a piece of glass typically used within the optical window that can be easily scratched or broken and provides a loss during the illumination process. By using the functional components of the optics module to form the recessed optical window, manufacturing costs to secure and replace a typical glass window contained therein can be eliminated, size of the optics module is reduced, and any contaminates that gather around the optics module can be easily removed by the user.
