摘要:
An optically addressable display includes a plurality of receptor and emitter pairs where each pair is for receiving optical display information and for generating light indicative of the display information. Each individual receptor and emitter pair is coupled electrically by an associated control circuit that facilitates driving the emitter so it generates either the received display information or annotation information generated by a light wand that is capable of being optically coupled to individual ones of the plurality of receptors. Each control circuit has a pulse density capture circuit that receives a pulse train signal indicative of a desired brightness or hue levels and drives an individual one of the emitters on and off at a determined duty cycle to produce the desired brightness or hue levels. In another embodiment sets of receptor and emitter pairs are grouped in cells, where each cell is capable of generating N of shades of different colors.

A display system and method are provided. The system typically includes a display configured to control visible light, as well as to sense an optical signal projected thereon, the display being adapted to freeze a projected image by storing the optical signal associated with the live projected image in memory associated with the display and controlling visible light corresponding to the stored optical signal to form a frozen projection image.
摘要:
A display system including a projector and a display. The projector is adapted to wirelessly transmit image information associated with an image to be displayed. The display includes a plurality of display cells that are configured to collectively display the image based on the image information transmitted by the projector. Each display cell includes a receiver, display element and storage device. The receiver is configured to wirelessly receive a portion of the image information, and the storage device is adapted to store a control signal corresponding to the received portion of the image information. The display element is configured to display the corresponding portion of the image in response to application of the control signal from the storage device.
摘要:
A method is disclosed for positioning an optical labeling mechanism substantially close to a particular track of a labeling surface on an optical disk. The method can include the operation of positioning the optical labeling mechanism adjacent to the particular track. A further operation can be measuring a first surface texture of the labeling surface using the optical labeling mechanism. Another operation can involve positioning the optical labeling mechanism adjacent to a different track. A further operation can be moving the optical labeling mechanism from the different track toward the particular track location. Another operation can involve measuring a second surface texture of the labeling surface using the optical labeling mechanism. A further operation can be comparing the first and second surface textures to determine if the optical labeling mechanism is positioned substantially near the particular track.

A method of creating a memory circuit preferably includes (1) forming a first plurality of select-lines in a plane substantially parallel to a substrate, (2) forming a second plurality of select-lines in a plane substantially parallel to the substrate, where the second plurality of select-lines is divided into first and second groups, where the first group is formed in a direction normal to that of the first plurality of select-lines and the second group is formed in a direction substantially diagonal to that of the first group, (3) forming a plurality of pillars normal to the substrate, and (4) forming an array of memory cells, each memory cell being respectively coupled to a pillar and one of each of said first and second pluralities of select-lines.
摘要:
Interconnection structures for integrated circuits have a first array of cells, at least a second array of cells parallel to the first array, and interconnections disposed for connecting cells of the first array with cells of the second array, at least some of the interconnections being disposed along axes oriented obliquely to the first and second arrays. First and second sets of oblique axes of interconnections may be parallel or opposed to each other. The interconnections may include obliquely slanted pillars or stair-stepped pillars disposed along the oblique axes. Methods for fabricating and using such structures are disclosed.

A recordable medium having a data side and a label side has one or more template patterns printed on the label side, and has at least first indicia including a template-reference-position mark.
摘要:
A method of an embodiment of the invention rotates an optical disc having an optically writable label side. The optical disc is radially scanned with a laser incident to the optically writable label side, from a first edge of the optical disc to a second edge of the optical disc. While the laser is radially scanned from the first edge to the second edge of the optical disc, a first radius at which markings have not been written to the optically writable label side of the optical disc, next to a second radius at which markings have been written to the optically writable label side of the optical disc, is detected.
摘要:
This invention relates to a label having improved security, comprising: a label substrate having a recessed portion; a layer of an energy activated material substantially located along a section of the recessed portion; and an optically transparent cover located substantially over the energy activated material such that the cover is substantially located within the recess.
