摘要： A clock system for a fiber optic gyroscope is provided that includes a highly-tunable clock for the bias modulation and a separate asynchronous high-speed clock for the photodetector sampling. By separating the two clocks rather than using two derivatives of the same clock, the clock system and method can provide both the tunability objective of the bias modulation clock and the high-speed objective of the sampling clock, while using readily available, lower performance, radiation-hardened electronics parts.

摘要： According to the preferred exemplary embodiments of the present invention, there is provided a phase jump amplitude and timing controller for suppressing the voltage-dependent errors responsible for the dead band. 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. The phase/voltage jump is provided at a frequency regular enough to ensure that the fiber optic gyroscope will not have enough time to settle into the dead band before the phase/voltage jump is supplied to the loop closure electronics. By providing a recurring phase/voltage jump with amplitude sufficient to move the signal out of the dead band, the loop closure electronics averages the voltage-dependent errors over the full feedback voltage range. This error averaging process effectively eliminates the voltage-dependent errors that cause the dead band phenomenon and allows the loop closure electronics to sense the actual rate of rotation for the fiber optic gyroscope.

摘要： 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.

摘要： 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.

摘要： 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.

摘要： A video reproducing/recording and playing system and a method thereof for setting and playing video sections are provided. The system includes a host computer with a data buffer and a database, a video module, and a monitor. While continuously receiving video signals, the video module sets a first section index when a scene difference between a first frame and a second frame represented by a portion of the video signals is greater than a predetermined scene difference wherein the first section index points to a start time of the second frame. Then, the video module stores the first section index and stores the video signals corresponding to the second frame into the data buffer. After retrieving the first section index, the monitor presents the video signals from the second frame points by the first section index.
