  • Patent number: 10219000
    Abstract: A method of performing motion vector correction in a sequence of video frames includes receiving, at a processor, a frame of video frames at a received rate lower than an original frame rate, identifying motion vector candidates for a frame in the sequence of video frames, detecting a cadence of the sequence of video frames using the motion vector candidates, scaling the motion vector candidates according to the cadence to produce scaled motion vector candidates, calculating motion vectors for a frame in the sequence of video frames using the scaled motion vector candidates, and interpolating at least one new frame of video data using the motion vectors.

  • Patent number: 9103968
    Abstract: A method and apparatus for detecting a group of parameters. An optical signal is sent into an optical sensor unit comprising a first reflective structure, a second reflective structure, and a cavity system located between the first reflective structure and the second reflective structure. The first reflective structure is configured to be associated with an optical fiber. A response generated by the optical sensor unit is detected. The group of parameters is identified from the response.

  • Publication number: 20140130214
    Abstract: A fiber-facet AFM probe enabling high-resolution, high sensitivity measurement of a sample surface is presented. AFM probes in accordance with the present invention include an optically resonant cavity that is defined by two mirrors, at least one of which is a photonic-crystal mirror. One of the mirrors is movable and is mechanically coupled with an AFM tip such that a force imparted on the tip by an interaction with the sample surface induces a change in the cavity length of the optically resonant cavity and, therefore, its reflectivity.

  • Publication number: 20100263204
    Abstract: A method of manufacturing a composite tape used for producing printed circuit board is provided. The method includes the steps of: providing a mold-releasing layer on a first surface of a paper substrate layer; providing a composite adhesive layer on a second surface of the paper substrate layer, the composite adhesive layer being formed by polyurethane adhesive, polyester adhesive, or a mixture thereof; providing a plastic layer on a second surface of the composite adhesive layer; and providing an adhering layer on a second surface of the plastic layer. The composite tape according to the invention can not only bear high temperature up to 280° C. for a predetermined time, but also the tape does not detach or warp.

  • Publication number: 20060243611
    Abstract: A cigarette package, in some embodiments, can comprise a tray, a cover coupled to the tray, and a cigarette holder secured to the tray and adapted to move between a first position substantially inside the tray and a second position substantially outside the tray. In some embodiments, a cigarette package can comprise a tray, a cover adapted to slide on the tray between a closed position and an open position, and a cigarette holder coupled to a first wall of the tray and adapted to move between a first position and a second position as the cover slides on the tray. In some embodiments, a consumer can operate a cigarette package of the present application with one hand to dispense at least one cigarette.
