Abstract: 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.

Abstract: 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.

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.

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: A simple and robust heat actuated steering device for use with mirrors and other optical components of optical telecommunications equipment is described, together with systems which implement such devices. The device uses differential heating between two legs of a flexured mount to allow tilting that can be used to steer an optical beam. Disturbances in the optical alignment, caused by temperature changes, of an optical device containing this component can be compensated by measuring the device temperature and using this to determine a command signal, for example as provided through a lookup table, to correct for device misalignment. Techniques for calibrating the device and establishing the correction data are also disclosed.

Abstract: An apparatus using a resonator probe for determining an electronic property of a conductor across a dielectric. The apparatus has a device for inducing lateral mechanical oscillations of the resonator probe and a voltage source for producing a voltage difference between the resonator probe and the conductor to create an electronic drag between the conductor and resonator probe, thus damping the mechanical oscillations of the probe. The electronic property, such as charge carrier mobility, surface resistance, charge carrier lifetime and the number of charge carriers is determined from the damping experienced by the probe.

Abstract: Different solvents for a dampening fluid are disclosed. The solvent is a volatile hydrofluoroether liquid or a volatile silicone liquid. Such liquids have a lower heat of vaporization, a lower surface tension, and better kinematic viscosity compared to water, which is the conventional solvent used in dampening fluids. The dampening fluids, which are relatively nonpolar, can be used in a combination with polar inks to form a new type of digital lithographic printing system.
