摘要:
An optical device and methods thereof are described. The device includes a first light source adapted to emit light onto a surface, and a detector adapted to receive light reflected from the surface. The reflected light produces a speckle pattern. The distance between the optical device and the surface can be measured using a quantifiable attribute associated with the speckle pattern.

A test system in accordance with the invention includes a field effect transistor (FET) sensor that is operable to detect an electric field present in an area located adjacent to a sensor surface of the FET sensor and generate thereby, a change in the drain-source current of the FET sensor. The change in drain-source current is typically detected by a current detector of the test system.

An imaging system comprising a filter array adapted to filter electromagnetic waves, a lens array adapted to focus electromagnetic waves, and an image sensor configured to receive the focused electromagnetic waves. The filter array and the lens array are configured into elements that filter and focus electromagnetic waves that represent an object image window onto portions of the image sensor and each portion of the image sensor receives filtered electromagnetic waves that represent the object image window from one of the elements.

Imaging systems and methods are provided. One exemplary system incorporates multiple lenses that are individually configured to receive visible light from an object to be imaged, and to direct this light upon a corresponding sensor array. Luminance information is then derived from signals generated in one or more of the sensor arrays. When chrominance information is desired, an optical filter is interposed between a lens and the corresponding sensor array. The mosaic pattern contained in the optical filter is tailored to provide advantageous chrominance information. One or more such filters with different mosaic patterns may be employed. The luminance and chrominance information obtained from the sensor arrays are combined to generate an image of the object.

The color image sensor generates an image signal representing a subject. The color image sensor has a light sensor and imaging elements arranged to form images of the subject in light of different colors on respective regions of the light sensor. The light sensor includes sensor elements and is operable to generate the image signal in response to light incident on it.

A print controller with simplified video data storage operation. A single microprocessor provides a controller with a start address and a start command. The controller monitors a stream of digitized video data as it fills a two part serial register in a video random access memory ("VRAM"). As each successive part of the serial register is filled, the controller writes the contents of the filled part of the serial register to the VRAM. Upon receipt of a signal indicating the end of the image, digitized video data remaining in the register is written to the VRAM. Images are effectively streamed in, as opposed to the line by line storage of images used in known print controllers.
摘要:
A document entering a document transport system is assigned an address identification corresponding to a storage location in a shunt command storage member and the shunt command information at the designated location is addressed as the document approaches a document shunt location to determine if the document is to be shunted or permitted to continue in the transport.
摘要:
The movement of a document through a transport system is simulated electronically and compared to the actual movement of the document to detect a document feed jam.

A touch device includes a touch panel and a vibration device to provide tactile feedback to a user to locate a key on a display of the touch panel. A processor generates a drive signal to the vibration device when the position on the display touched by a finger or stylus corresponds to a location of a key on the display. The vibration device causes the display to vibrate in response to the drive signal to provide a tactile key location indication to the user while the key is touched.

An emulated hard key that emulates a key of a user-selected keyboard is generated on a reconfigurable keyboard. In one exemplary embodiment, the reconfigurable keyboard has an array of microchambers. Each microchamber is operable to change from a first height to a second height. A keyboard emulator controller controls the array of microchambers to set a first group of microchambers to the second height. When set to the second height, the first group of microchambers collectively emulates a first key of the user-selected keyboard.
