20080303900 | Miniature Low Cost Pan/Tilt Magnetic Actuation For Portable And Stationary Video Cameras - A pan/tilt apparatus for a camera includes a base, a stage mounted on the base to rotate around a vertical pan axis, an optical apparatus mounted on the stage, a pan actuating mechanism, and a tilt actuating mechanism. The optical apparatus includes a frame that supports a magnetic structure and a mirror such that they are pivotable around a horizontal tilt axis. The mirror receives an image directed along an incident axis, and redirects the image along the pan axis, e.g., to a camera that is disposed on or below the base. The pan actuating mechanism engages and rotates the stage into a desired pan direction. The tilt actuating mechanism modulates (alters) a magnetic field applied to the mirror/magnetic structure by, for example, moving a permanent magnet that is mounted on the base. | 12-11-2008 |
20090161197 | AGILE BEAM STEERING MIRROR FOR ACTIVE RASTER SCAN ERROR CORRECTION - Scan line position error resulting in banding, bow, skew, etc. is corrected by way of an agile beam steering mirror assembly in a ROS printing system and the like. The agile beam steering mirror system comprises a piezoelectric bending actuator fixedly mounted to a substrate at a proximate end thereof. A mirror structure is mounted at a free distal end of the bending actuator. Voltage applied to the bending actuator causes rotation of the mirror to thereby correct for positional errors of the scan line. Correction waveforms may be stored in control memory associated with the agile beam steering mirror assembly. A capacitive sensing circuit using a sensing electrode located beneath the free end of the bending actuator may be used in a feedback arrangement to determine and control mirror position. | 06-25-2009 |
20090322845 | ANISOTROPICALLY CONDUCTIVE BACKSIDE ADDRESSABLE IMAGING BELT FOR USE WITH CONTACT ELECTROGRAPHY - An addressable imaging belt for use in printing applications having embedded anisotropically conductive addressable islands configured for electric contact on a first side of the belt by a write head consisting of an array of compliant cantilevered fingers with contact pads/points to which a voltage can be applied. The conductive addressable islands electrically isolated from one another and extending substantially through the thickness of the belt in order to allow charge to flow through the belt towards a second side of the belt, in order to form a latent electrostatic image on the second side and develop this latent image by attracting colorized toner or other electrically charged particles to the second side. | 12-31-2009 |
20100085585 | DIGITAL IMAGING OF MARKING MATERIALS BY THERMALLY INDUCED PATTERN-WISE TRANSFER - An imaging system including an image receiving structure including a material layer having a tunable energy transfer characteristic; and an energy source to emit an energy beam at the material having the tunable energy transfer characteristic such that marking material is pattern-wise transferred to the image receiving structure. | 04-08-2010 |
20100231639 | VARIABLE DATA IMAGING - According to some embodiments, a method for printing an image on a substrate includes applying a clear liftoff material to a surface of the substrate to form a sacrificial pattern, the clear liftoff material being substantially optically clear, and applying a first marking material to the surface of the substrate to form a first static pattern, a portion of the first static pattern arranged directly above a portion of the sacrificial pattern. The method further includes removing the portion of the first static pattern from the surface of the substrate, and removing the sacrificial pattern from the surface of the substrate. | 09-16-2010 |
20110012980 | LATENT RESISTIVE IMAGE LAYER FOR HIGH SPEED THERMAL PRINTING APPLICATIONS - An imaging system including an image receiving structure including a tunable-resistivity material; and an energy source to emit an energy beam at the image receiving structure to pattern-wise program the tunable-resistivity material. A resistivity can be pattern-wise changed. Marking material can be pattern-wise adhered in response to the pattern-wise changed resistivity. | 01-20-2011 |
