  • Publication number: 20080225419
    Abstract: A varifocal mirror and a camera module comprising the same are disclosed. The varifocal mirror comprises a substrate, a thin film having a circumference supported by the substrate and a variable radius of curvature, and a reflective plane attached to the thin film to reflect light. The reflective plane has a radius of curvature varying in response to variation in the radius of curvature of the thin film. The camera module embodies focus and optical zoom functions via actuation of the varifocal mirror instead of using an electromagnetic actuator, a step motor and the like when adjusting positions of lens units, significantly reducing a volume of the overall system. With this structure, the camera module can be applied to various portable digital assistances requiring a minimized camera module, such as PDAs, mobile phones and the like.

    Abstract: A multiple aperture optical system is provided that overcomes many limitations of wide field of view imaging systems. A basic component of the multiple aperture optical system is an “eye strip”, which comprises an array of imaging apertures physically mounted onto a flexible circuit strip and a master processor. Each imaging aperture generates an aperture output based on the imaging aperture's field of view. The master processor takes as input the aperture outputs generated by the apertures on the eye strips, and generates an output in response. In one embodiment, the multiple aperture optical system enables obtaining an omnidirectional image in a structure that is thin and can be physically conformed to an underlying structure.

  • Publication number: 20080225424
    Abstract: A method of making optical devices includes applying an energy sensitive protective material and an energy sensitive advanced optical material to a surface. The surface can be on the optical device or on a carrier, such as a thin sheet, to be applied to the optical device. Light energy is applied through a special production filter to cure the energy sensitive protective material on the surface while blocking light energy outside a selected wavelength spectrum from reaching the material. A portion of the optical device can then be masked, and light energy outside the spectrum filtered by the special production filter can be applied to activate the unmasked portion of the advanced optical material. The special production filter allows curing of the protective material using light energy in a limited (e.g., visible) spectrum so that the advanced optical material can be activated using light energy in the ultraviolet spectrum.

  • Publication number: 20080225427
    Abstract: Dynamic fly height (DFH) control is obtained for a read/write head by use of a heating element having two laterally separated heat sources symmetrically spaced around the track center line of the head. The two heating sources create a protrusion profile relative to the undistorted ABS that recesses the read element and main write pole at the track center line relative to off-track positions. The resulting DFH control also protects the head from HDI events that are either the result of calibration procedures or normal HDD operation.

    Abstract: A method and apparatus for restoring power to loads connected to a feeder powered by a power source. The feeder is provided with a plurality of switching devices and a master electronic device which is in operative communication with the switching devices and has a plurality of power restoration plans stored therein. Upon occurrence of a fault in a zone of the feeder, the identity of the switching device which is closest to and upstream from the faulted zone relative to the power source is used in order to select a power restoration plan and restore power to some or all the loads connected to non-faulted zones of the feeder from one or more additional feeders.

  • Publication number: 20080225456
    Abstract: An over-current protection circuit of a semiconductor circuit including a power transistor for outputting current output, a first output current detection circuit and a current limiter circuit for limiting the output current by stopping the output current of the power transistor for a predetermined period in response to a first detection signal from the output current detection circuit when the output current of the power transistor reaches a predetermined limit value. The over-current protection circuit has an output current detection transistor current-mirror connected to the power transistor and a second output current detection circuit for generating a second detection signal according to an output current of the output current detection transistor when the output current reaches the predetermined limit value. Further, the output current of the power transistor is cut off for the predetermined period by operating the current limiter circuit in response to the second detection signal.

  • Publication number: 20080225457
    Abstract: The invention relates to a safety switching device, with which a safety-related device, preferably an electric drive, can be set into a safe state. The safety switching device (900) has a microprocessor or microcontroller (822), which can set, for example, an electric drive to be protected into a safe state both if an emergency circuit breaker, protective door switch, and/or two-hand switch is activated and also if there is faulty operation of the safety-related device or electric drive. For this purpose, the microprocessor (822) is preferably implemented such that it can determine from at least one analog signal to be measured whether a predetermined parameter, preferably the amplitude of the analog signal, lies outside a predetermined operating range. In addition, the microprocessor (822) can be a component of a safety device (810) which is constructed for multiple-channel control of a safety-related electric drive.

  • Publication number: 20080225460
    Abstract: An apparatus and method for minimizing contamination buildup on corona emitters that are employed in an ionizer. Contamination buildup control is accomplished with solely electronic means. High voltage is applied to the emitters with waveforms that serve to push contaminants away from the emitter, rather than attracting contaminants toward the emitters. The results are fewer cleaning cycles, more time between cleaning cycles, and more stable ionizer operation.
