Abstract: A connective unit to connect a roller with a seat's leg is disclosed. The connective unit comprises a supportive arm, a plastic cylindrical member, a pivotally connective member and a roller. The plastic cylindrical member may engage with a cylindrical hole provided in the supportive arm. The upper end of the pivotally connective member may engage with a first connective hole and the lower end of the pivotally connective member may engage with a second connective hole of the roller. Thanks to presence of the plastic cylindrical member, when the pivotally connective member rotates and causes the roller to rotate with it, the supportive arm doesn't have any contact with the pivotally connective member and thus noisy friction and impacts between them as in the prior art may be avoided. Therefore, the plastic cylindrical member is difficult to wear out as the pivotally connective member rotates.

Abstract: The wheel device contains a base, an axle rotatably running through the base, two sleeves each having an axial through channel for the axle to run through; and two wheel members each having an axial first socket open to an inner side of the wheel member for joining with an end of the axle. The axle has a first neck section adjacent to each end of the axle with a small diameter than the axle's other sections. Along the axial through channel of each sleeve, there is a narrower first collar section. Inside the first socket of each wheel member, there is a narrower second collar section. After the axle runs through a sleeve and joins to a wheel member, the more extensive first and second collar sections are jointly embedded in the sleeve's more reduced first neck section, thereby enhancing the wheel device's operational life and reliability.

Abstract: A method for controlling electrical power of light emission diodes (LED) is provided. The above method comprises steps of providing a supply voltage to the LED driver; providing a driving current to the LED by the LED driver; obtaining an operating voltage of the LED; and adjusting the supply voltage according to the operating voltage of the LED.

Abstract: A plasma system with an injection device is provided. The plasma system comprises a plasma cavity and an injection device. The plasma cavity comprises a first electrode and a second for generating plasma. The injection device comprises a plasma injection tube and at least a reactant injection tube. The plasma injection tube is connected to the plasma cavity. The plasma injection tube comprises an inlet, an outlet and an outer sidewall. The plasma injection tube injects the plasma from the inlet and guides the plasma out through the outlet. The outer sidewall has a width decreasing from the inlet to the outlet. The reactant injection tube is disposed outside of the outer sidewall. The reactant injection tube injects a reactant to the outer sidewall so that the reactant flows along the outer sidewall toward the outlet and mixes with the plasma at the outlet.

Abstract: A projector comprises a light-emitting device for generating light beams, a reflector for focusing the light beams to a predetermined region, a light integrator positioned at the predetermined region and a brightness-adjusting module for adjusting the brightness of the projector by changing the relative distance of the reflector and the light integrator. Preferably, the reflector is an elliptical reflector having two foci, the light-emitting device is positioned at one of the two foci and the other focus is laid in the predetermined region. The present method for adjusting the brightness of a projector is characterized in adjusting the distance between the light integrator and the reflector to adjust the brightness of the projector.

Abstract: A digital presenter has a base, an image acquiring device with an automatic focusing function, and a flexible support device connected between the base and the image acquiring device.

Abstract: Apparatus for processing video signals and which can be connected with a personal computer for further processing. An analog to digital converter samples and converts input NTSC composite video signal into digital signal for subsequent processing. A phase-locked loop provides sampling clock signal to the ADC, and also ensures accurate sample phase. Based on a theory that human eye is more sensitive to the luminance component of video signals, a double sampling circuit is included which double samples the luminance component of a video signal to improve the overall resolution of an image.

Abstract: A chip supplying apparatus for picking chips from a wafer positioned on an elastic film is disclosed. The chip supplying apparatus includes a shifting device, a clutch device, a film-expanding device, and a chip-picking device. In the present chip supplying apparatus, the input torque provided by the clutching device for driving the film-expanding device to perform a film-expanding operation is orthogonal to the resulting rotation torque of the film-expanding device. Therefore, when the film-expanding operation is performed, the film-expanding device will not shake. In other words, the present chip supplying apparatus can perform stable film-expanding operation.

Abstract: An apparatus for converting and scaling non-interlaced VGA signal to interlaced TV signal suitable to be displayed on a TV video screen is disclosed. The apparatus includes an analog to digital converter, a vertical scaling down device, a vertical scaling up device, a horizontal scaling down device, a horizontal scaling up device, a memory unit, a memory controller, and a digital to analog converter. The apparatus is capable of scaling the non-interlaced VGA signal to interlaced TV signal with any desired scaling size both in horizontal direction and in vertical direction to meet the requirement of displaying operation of the TV screen.

Abstract: A computer-aided embroidery method for preparation and testing of a predetermined pattern is disclosed. The method comprises the steps of (a) comparing the size of said pattern with an embroidery table device to determine if an intended embroidery operation will exceed a defined boundary of said embroidery table device; (b) determining an embroidery frame; and (c) providing a completed simulation and a trial embroidering process within said embroidery frame without actually lowering a needlebar for testing the validity of a pattern layout. A machine implementing this method is also disclosed.

Abstract: A needle-changing mechanism for use in a multiple-needle embroidery sewing machine is disclosed for controlling the changing of a selected sewing needle to a working position on the sewing platform of the sewing machine. The needle-changing mechanism includes a sensing plate having a gap portion sandwiched between two solid side portions. The position of the gap portion is changed by moving the sensing plate according to which needle is currently selected as the working needle. A plurality of photo detectors equal in number to the number of the needles of the sewing machine are arranged at equal intervals along a straight line relative to the axial orientation of the sensing plate such that the gap portion and the side portions of the sensing plate cause the photo detectors to output a pattern of positioning signals. A controller, which receives and processes output signals from the photo detectors, is used to control the movement of the needles so that the desired needle is positioned as the working needle.
