Abstract: A phase jump amplitude and timing controller is used in a fiber optic gyroscope for suppressing color noise. The phase jump amplitude and timing controller inserts a phase/voltage jump into the feedback signal of the loop closure electronics of the fiber optic gyroscope. This phase/voltage jump breaks the repeated pattern of the drive signal. The IOC time-dependent characteristics are totally eliminated by the randomized feedback signal because no repeated signal is applied to the IOC. The randomized amplitude is preferably within the full ±π phase such that the optical errors average to zero. A fixed frequency higher than the interested spectral region can shift the color noise to higher frequency. A randomized frequency can spread the color noise over full spectrum, and totally eliminate the RDS. In other words, the color noise caused by the nonlinearity of the driving circuit and IOC spreads out over a wide range of spectrum such that no distinct frequency peaks are apparent in the spectral domain.

Abstract: A disposable syringe after one time usage includes an outer tube having an inner teeth set formed on the inner wall of the outer tube and an inner tube having an outer teeth set formed on the outer wall of the inner tube and a safety guide. The inner teeth set of the outer tube meshes with the outer teeth set of the inner tube. The single direction design of the teeth sets allows the outer tube to be pulled away from the inner tube, but not to be pushed back. The pulling force of the outer tube will pull the safety guide to form a damaged groove and the outer tube is adapted to enclose a needle so that the needle is not exposed outwardly, which prevents the needle from poking people accidentally. The syringe is unable to be reused.

Abstract: A liquid crystal display device having a sealing material close to display area while maintaining a uniform liquid crystal cell gap is disclosed. The liquid crystal display comprises two transparent electrode substrates having a trench near the display area to stop the sealing material overflowing to display pixels. Thus, the effective display area of a liquid crystal display device is increased by dispensing a sealing material to a trench area at a predetermined position surrounding the display area. A spacer used in the sealing material is larger in size than that used in the display area to compensate the depth of the trench. After the liquid crystal is injected into the space surrounded by the substrates and a sealing material, a uniform liquid crystal cell gap over the entire display area is obtained. The liquid crystal display device thus obtained results in a closer distance between the sealing material and display area without any unevenness in color over the entire display area, and lends itself very useful as unit display device or as one of the panels in a tiled liquid crystal display device.
