Abstract: A liquid crystal display (LCD) device may include a scan line that is parallel and adjacent to a compensation signal line. A compensation signal transmitted on the compensation signal line may be the inverse of a scan signal transmitted on a scan line. Consequently, feed-through voltage may be reduced and gray levels may be more properly displayed in pixels.

Abstract: A manufacturing method of an artificial strip for imitative rattan/willow furniture is to mix unicolor or multicolor polyethylene (PE) with a catalyst that makes the mixture foam after heating. Then, the mixture is extruded via special shaped opening on a shaping mold to perform the artificial strip with chap and crank patterns. Moreover, the color distribution on the artificial strip can be performed evenly or unevenly to create more versatile appearance. Thereby, the artificial strip has a verisimilitude texture approximately like the natural willow or rattan strips to make the manufactured imitative rattan/willow furniture have excellent appearance.

Abstract: A safety lock mechanism of a lighter, including a lighter main body, a press key and a safety shift plate. A gas container for containing gas and an ignition unit are disposed in the lighter main body. The press key is disposed on upper side of the ignition unit. A top side of the press key is formed with a slot perpendicular to a pressing direction of the press key. The safety shift plate is slidably disposed in the slot of the press key. The safety shift plate is pushed by a resilient member, whereby in normal state, one end of the safety shift plate extends into a dent of the lighter main body to restrict the press key from being pressed down. Under such circumstance, the lighter is in a locked safety state. When a user desires to ignite the gas, the user only needs to first outward push the safety shift plate along the slot with a finger. At this time, the end of the safety shift plate is extracted from the dent and the press key is released from the restriction.

Abstract: A system, modules, means, and computer readable media for and a method of compensating disturbances that cause track shape irregularities on a disc in a disc drive during a disc servo-writing process performed by a servo-writer are disclosed. The disturbances substantially attributable to a nonrepeatable runout (NRRO) are present during the servo-writing process. A substantial component of the NRRO is a cage frequency generated by a spindle motor mechanism in the disc drive. A reference cage frequency is determined during a servo-writing process by using a position sensor. Then a feed-forward input signal is determined based at least on the reference cage frequency during the servo-writing process. In addition, the feed-forward input signal is feed-forwardly transmitted to the servo-writer.

The slant plane and the perpendicular plane work with the stoppers on the fixing ring to ensure that the valve can be easily closed but is difficult to open.

Abstract: A control circuit and method for managing multicast packets is implemented in a network switch to improve the efficiency of bandwidth utilization. The control circuit comprises an internal control buffer which is subdivided into multiple storage sections. Each storage section consists of buffer-control records including valid bit, counter value, control pointer, and tag number. When the tag number of a coming multicast packet indicates that the internal control buffer is full, the control data of the coming multicast packet will be copied to an external control memory. On the other hand, the control data of the coming multicast packet will be directly stored in the control buffer if otherwise. After each multicast packet transmission, the control data in the control buffer can be accessed and updated. Consequently, the traffic between the network switch and the external memories can be reduced to the minimum, thereby to improve the efficiency of the bandwidth utilization.
