Abstract: 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.

Abstract: A 1×N wavelength selective switch which can function as a dynamic channel equalizer when N=1. In an exemplary arrangement, the present invention is a free-space device that includes a linear array of micromachined reflective elements for beam steering of individual wavelength channels. In at least some embodiments the array of reflective elements of the present invention provides a substantially seamless design such that the optical spectrum appears flat across the transition between actuators. Various embodiments provide high channel bandwidth with flat-top channel performance, low polarization dependence loss, low vibration sensitivity, extinction ratios greater than 40 dB over all temperatures, and very low levels of electrical and optical channel cross-talk.

Abstract: 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.
