摘要:
This disclosure describes a lighting apparatus comprising a light hue modulating device that generates compensating light to adjust the light to a desired hue within a space regardless of the hue of the ambient light within the room.
摘要:
Optical density is enhanced on print media darkened by exposure to electromagnetic radiation. The print media is divided into at least one track. A defocused spot of electromagnetic radiation is created within the track. The defocused spot of electromagnetic radiation darkens the print media within the track.
摘要:
A method of using electromagnetic radiation to control exposure of media to electromagnetic radiation is presented. The method includes rotating the media and sensing a frequency of electromagnetic radiation radiating from a rim of the media with a stationary detector. Exposure of the media to electromagnetic radiation with a movable source is controlled with the sensed frequency to provide increased accuracy.
摘要:
An optical focusing system is configured to generate a data profile, wherein the data profile is configured to provide signals for operation of an actuator. Application of the signals from the data profile results in focus of optics within a label region of an optical disc. An image is printed on the label region of the optical disc while the optics focus on the label region of the optical disc by applying signals to the actuator according to the data profile.
摘要:
An optical disc of an embodiment of the invention is disclosed that includes an optically writable label side on which marks are optically writable. The optical disc includes a plurality of tracks on the optically writable label side. Each track has written thereto a repeating pseudorandom series of marks.
摘要:
This invention relates to a receipt generating apparatus, comprising: an article that has been purchased; and a receipt portion located substantially on the article such that the receipt portion includes an energy activated material section upon which selected receipt markings are placed.
摘要:
Disclosed are various systems, methods, and programs embodied in a computer readable medium for calibration of a lens position in an optical disc drive. In one embodiment, a method is provided that comprises manipulating a lens focus actuator to relocate the lens from a first position to a second position. The lens substantially focuses a laser onto the surface of the optical disc when in the second position. The method also comprises determining a first input setting delta to the lens focus actuator that corresponds to a predefined position offset of the lens. The first input setting delta is determined based upon a second input setting delta corresponding to a distance between the first position and the second position.
摘要:
A multi-function digital media drive, has an optical pickup unit (OPU) configured to read data from or write data to a data layer of a digital medium, the OPU being associated with an OPU sled arrangement; an optical print head (OPH) configured to write to a labeling layer, the OPH being associated with an OPH sled arrangement, the OPU and the OPH being positioned on opposite sides of the digital medium; a motor; and a drive train configured to selectively supply motivating rotational energy from the motor to at least one of the OPU sled arrangement and the OPH sled arrangement.
摘要:
An optical printhead for a medium including material that forms an optically visible spot in response to energy of a predetermined wavelength, the optical printhead includes a laser configured to impart energy of the predetermined wavelength to the material through a fixed-focus lens arrangement.
摘要:
A method is provided for recording visible marks on a recording medium using an input beam generated by an electromagnetic radiation source. The method comprises (a) substantially collimating the input beam to provide a substantially collimated beam, and (b) applying the substantially collimated beam to the recording medium to provide the visible mark on the recording medium.
