  • Patent number: 6219475
    Abstract: The device concerns measuring the propagation and bending losses that take place in the individual mode of the multi-mode waveguide. The method applied is a new one comprising butt-couple and prism-couple together with phase-modulation method. Electrodes are made on the waveguide, and applied with voltage. The electro-optical effect is used to modulate the effective length of the waveguide in forming a Fabry-Perot etalon. From here, the contrast of the butt-couple's output and the loss can be measured. At the same time, as the prism-couple is able to separate the multiple modes individually, and measure the contrast and loss of each mode through every output mode which are then compared with the butt-couple, each mode's propagation and bending losses values of the multi-mode waveguide can be derived.

  • Patent number: 6216500
    Abstract: A device for unlocking a tubular-type door lock in conjunction with the indoor handle is disclosed. A hollow shaft is fitted into the outdoor plate, while a hollow sleeve is axially received in the hollow shaft to be movable in opposite directions. The sleeve is normally and rotatably positioned in the opening of the outdoor plate to be unlocked, but selectively engages with the locking slot of the outdoor plate to be locked. A ratchet unit, consisting of locking and unlocking ratchets, is received in the sleeve, thus being operable in conjunction with the indoor handle to selectively move the sleeve. The two ratchets, individually having a ratchet face, engage with each other at their ratchet faces to be relatively slidable on their slope surfaces in conjunction with the indoor handle, thus selectively and axially moving the sleeve from the locked to the unlocked position.

  • Patent number: 6219103
    Abstract: An input first video signal is converted by video format conversion into a second video signal to be encoded. The number of effective scanning lines of the second video signal is different from the number of effective scanning lines of the first video signal. The first video signal is further converted into a third video signal for which spatial aliasing noise is suppressed. The motion of each picture carried by the third video signal is estimated to obtain first motion vector data. The motion of the second video signal is searched using the first motion vector data to obtain second motion vector data. The second video signal is then encoded by motion-compensated prediction using the second motion vector data.

  • Patent number: 6217720
    Abstract: A method is described for depositing a complex optical multilayer coating on a substrate. The coating consists of multiple layers of at least two material types. The layers are sequentially deposited in a deposition chamber by reactive deposition; preferably sputtering, and the thickness of the deposited layers is determined one or more times during the layer deposition by taking optical measurements of the deposited layer and fitting theoretical values derived from a model of the deposited layers to the corresponding actual values obtained from said measurements. A process variable is continually controlled to ensure homogeneity of the deposited layers so that a valid thickness determination can be made from said theoretical model.

    Abstract: A resilient watertight light baton is disclosed having multicolored light source and power source mounted therein. The light sources are in electrical communication with the power source via interior electronics and solid state light sources. The exterior walls of the light baton are machined to effectively transmit light from the light source. The baton is extremely easy to use with only one hand and is controlled with a single button. By pressing the button the unit turns on and a steady glow color is emitted. By pushing the button again the color changes. By pressing and holding the button the selected color flashes. Ten colors or more may be selected or caused to flash using this procedure. This type of design is extreme robustness and can withstand extreme depths of submergence, making it useful for deep diving and submergence signaling applications.
