The present invention is to provide a method and apparatus for driving an AC PDP, where background luminance is reduced and the time required for a reset period is shortened while the stability and an address margin are sufficiently maintained, thus improving reset performance. The present invention provides a method of driving an Alternating Current (AC) Plasma Display Panel (PDP) comprising the steps of: applying a drive signal including a plurality of successive short pulses during the reset period; addressing at least a part of the discharge cells by applying data pulses to at least a part of said electrodes to enable selective discharge of said discharge cells according to image data during the address period; wherein, during the reset period, the plurality of short pulses form a plurality of discharges each duration of which is limited; and wherein a standardized wall charge is formed in each of the discharge cells due to the plurality of discharges so that the selective discharge is easily generated by application of data pulses during the address period.

The invention discloses a restoration device for billiards. The restoration device comprises a support which is arranged above a billiard table in a vertical corresponding mode and further comprises a controller. Cameras capable of shooting the whole table surface are mounted on the support, beams capable of moving along the length or width direction of the support are mounted on the support through a main translation mechanism, positioning lamps which move along the beams and capable of casting light spots are mounted on the beams through an auxiliary translation mechanism, and by means of the controller, a coordinate system corresponding to the billiard surface in a picture shot by the cameras can correspond to a coordinate system corresponding to the moving range of the positioning lamps, and the light spots cast by the positioning lamps can be moved to table surface positions corresponding to center positions of specified billiard balls. The restoration device is reasonable in structure, capable of indicating restoration positions accurately, small in restoration error, simple to operate, applicable to various billiard training, particularly applicable to professional billiards such as Snooker and capable of improving fairness and shortening restoration time.

A system and method for allowing adjustments of various parameters associated with the operation of charge-coupled devices adapted for use in biological analysis devices. Gate voltage signal applied to the CCDs can be adjusted to advantageously affect the manner in which charge is transferred from pixels. The manner in which transferred charges from the pixels are processed in a readout process can also be adjusted to advantageously change the speed of the CCD based detector. Various methods of performing such adjustments are disclosed.

The invention discloses an oil return structure of a hydrostatic trigger which belongs to a safe scavenging device that is additionally arranged on the hydrostatic trigger and has speed regulating function. The hydrostatic trigger comprises a base, an outer casing, an oil cylinder and a pump body which are respectively fixed on the base, an oil storing cavity which is formed between the outer casing and the oil cylinder, a piston rod which is arranged in the cavity of the oil cylinder and is provided with piston components that are arranged on a bottom end part, a top cap which is respectively connected with the outer casing and the top of the oil cylinder and is used for supporting the piston rod and a pump core which is arranged in the pump body. The scavenging structure of the hydrostatic trigger is characterized in that the base of the hydrostatic trigger is also provided with a spill valve which comprises a spill valve body, a spill valve rod, a first spring, a steel ball, a second spring, a washer, a third spring and a throttle valve body. The scavenging structure of the hydrostatic trigger has the advantages that the scavenging structure is simple; the scavenging structure facilitates the processing and the assembly of parts and the maintenance is convenient; quick drop during the idle loading and slow drop during the loading can be ensured.
