A chair includes a seat, a backrest, four legs, and a massage device positioned in the back and/or the backrest. The massage device consists of a frame and plural units of two rows of massage rollers. Each massage roller has plural annular projections and a center hole. An elongate shaft extends through the massage rollers of each row and pivotally connected to a side plate at two ends of each row. Two side connect plates combine pivotally the massage rollers rows with the frame by means of center short shafts pivotally connected with the side connect plates. So the two rows of the massage rollers can be rotated by movement of a user's body to get massage.

A method of controlling the capacitance of the TFT-LCD storage capacitor is provided. The gate dielectric layer of the TFT is composed of a silicon nitride layer, a dielectric layer and a silicon nitride layer, and the etching selectivity of the amorphous silicon layer over the dielectric layer is not less than about 5.0. Therefore, the dielectric layer can be an etching stop layer when a doped and an undoped amorphous silicon layers are etched to form source/drain stacked layers or a conductive layer is etched to form a gate on the gate dielectric layer. Hence, the dielectric layer thickness can be controlled; thereby the capacitance of the storage capacitor can be controlled.

This specification provides a burst synchronization and error detection device, which can generate in the synchronization module of the burst synchronization and error detection device a syndrome shared with the error detection module so as to decrease the computation time of the syndrome, shortening the processing time of error detection. The present invention also provides a burst synchronization and error detection method.

Novel techniques are disclosed for adjusting a power control setpoint to compensate for imperfect signal detection in a communication channel capable of discontinuous transmission (DTX). The power control setpoint is compensated for false detections by adjusting the power control setpoint by a dynamically determined setpoint back off amount upon detection of a Good frame. The amount of the setpoint back off is a function of the measured signal quality of the detected Good frame and the number of Erasure indications received immediately preceding the Good frame indication.

A stool includes a base and a post extending from a top of the base with a seat pivotably connected to a top of the post. A foot rest has a collar through the post extends and a recess is defined in an inner periphery of the collar. A cam member is received in the recess and a lever is connected to the cam member. A fastening member is received in the collar and mounted to the post. The cam member urges against an outside of the fastening member by operating the lever.
摘要:
The present invention is a novel and improved method and system for performing the pilot frequency tracking operation for coherent demodulation in a system employing a gated pilot signal. In particular, the present invention describes a method and apparatus in which two frequency tracking loops operate in parallel. The first frequency tracking loop performs its tracking operation based on the hypothesis that the received pilot is continuous throughout the frame's duration. The second frequency tracking loop performs the tracking operation based on the hypothesis that the received pilot is discontinuous and is only present for a portion of the frame's duration.

A light device includes a motor having a spindle, two posts provided beside the motor and each having a conductor coupled to an electric source. A circuit board is secured on the spindle and rotated in concert with the spindle and has one or more light members, and has two conductors for electrically coupling to the conductors of the posts respectively and for energizing the light member. The conductors of the circuit board may be electrically coupled to the conductors of the posts intermittently when the motor is energized, in order to energize the light members intermittently.
