摘要： A driver circuit for lighting applications that includes a power input circuit for receiving power; a light emitting diode (LED) output current circuit for interfacing with a light source; and a light emitting diode (LED) power supply circuit for controlling current to the light emitting diode (LED) output current circuit. A controller circuit is present in the circuit for signaling the light emitting power supply (LED) to control current to the light emitting diode (LED) output current circuit. The controller is reset by removing power to the controller. A smoothing capacitor is present for stabilizing at least an output voltage. The circuit further includes a current rectifying circuit that prohibits back current traveling from the smoothing capacitor to the controller circuit when the AC power is off.

摘要： Provided is a method for encoding parameter sets at slice level. The method includes: when there are one or more parameter sets, in which the coding tool parameters are identical to the coding tool parameters of a part of coding tools used for the current slice, in the existing parameter sets, encoding the identifiers of parameter sets into bit-stream of the current slice, wherein a parameter set contains common information of the coding tools used in the process of encoding/decoding slice(s). Correspondingly, also provided is a method for decoding parameter sets at slice level and a device for encoding and decoding parameter sets at slice level, which can make full use of the encoded parameter set information when the slice header refers to a plurality of parameter sets, implement flexible configuration of the coding tools used in the process of encoding/decoding slice(s) and reduce information redundancy.

摘要： A crank circular slider mechanism includes a crankshaft having at least one crank pin; at least one circular slider with an eccentric hole which fits over the crank pin; at least one reciprocating element with a circular slider-receiving hole, which receives the circular slider in a rotatable manner; and at least one dynamic balance rotary block with an eccentric hole that fits over the crank pin. The dynamic balance rotary block and the adjacent circular slider are fixed together. By means of proper selection of a mounting place and a mass of the dynamic balance rotary block, the mechanism can convert reciprocating inertia of the reciprocating element into rotation inertia so as to obtain a balancing effect. An internal combustion engine and a compressor may be equipped with the crank circular slider mechanism.

摘要： A general anatomic self-locking plate for medial acetabulum includes a left plate and a right plate mirrored with respect to the left plate. The right plate is a one-piece and includes a horizontal plate body and a vertical plate body. The horizontal plate body and the vertical plate body form a T shape. A through-hole is provided on the vertical plate body along a length direction thereof. Hole pathways of screw holes in the horizontal plate body lean downwardly along the free end of the horizontal plate body. The self-locking plate further includes stress bridges, automatic reduction holes and temporary positioning holes. An auxiliary apparatus of an anatomic self-locking plate for medial acetabulum includes a locking sleeve, a screw placing sleeve and a pair of gripping pliers. The right plate has excellent reduction and stable fixation, and is beneficial to accurately fix fractures without shaping and cutting during operation.
