Abstract: An assistance mechanism includes a base, a rotatable link, a lifting unit and a power unit which provides power to the lifting unit so that the lifting unit drives the rotatable link. A seat is connected to the rotatable link so that when the rotatable link is activated, the user sitting on the seat is transformed from a sit status into a stand status. This effectively assists the user who does not have sufficient muscle forces to stand up by the assistance mechanism.

Abstract: An illumination device includes a light source positioned on an illumination axis, a lens assembly having at least two biconvex lenses disposed on the illumination axis, and a reflector having a reflecting surface enclosing the lens assembly. The light source emits a first group of light beams which directly impinge of the lens assembly, and a second group of light beams which directly impinge on the reflector. The second group of light beams being reflected by the reflecting surface such that they surround the first group of light beams after being refracted by the lens assembly, without such second group of light beams impinging on the lens assembly.

Abstract: The present invention relates to a driving method of speaker and the driving circuit thereof by employing the technique of converting digital sound signals into corresponding driving signals to drive the speaker. The driving method of the speaker comprises the steps of dividing the digital sound data into higher bits data group and lower bits data group, converting one data group into driving signals represented as pulse height, and modulating the other data group into driving signals represented as pulse width. The driving circuit comprises pulse width modulation (PWM) circuit for modulating one data group into driving signals represented as pulse width and digital analog conversion circuit for converting the other data group into driving signals represented as pulse height.

Abstract: An illumination device includes a light source generating initial light beams, a lens assembly disposed on an axis, and a reflector comprising a reflecting surface. The initial light beams include a first and second reference light beams traveling along a first and second positions, respectively. The first reference light beam passes through the lens assembly to form a first predetermined light beam traveling away from the light source. A first angle is substantially formed between the first position and the axis. The second reference light beam is reflected by the reflective surface to form a second predetermined light beam traveling away from the light source. A second angle is formed between the first and second positions. The first angle is less than or equal to the second angle. The initial light beams are guided by the lens assembly and the reflector to emit the light beams in a projecting mode.

Abstract: The present invention relates to a motor shock prevention structure, which is a shock prevention structure disposed between a metal tube and a fixing hole of the bottom plate in a motor such that the metal tube and the bottom plate are not directly contacted. Moreover, the shock prevention structure includes integrating at least a shock prevention element and a gasket. As the shock prevention element is made of a flexible material being shock-absorbent and damping, the vibration amplitude during motor rotation won't be transmitted to the bottom plate and the electronic system due to the damping function of the shock prevention element, and the resonant effect and noise out of vibration occurring in an electronic system is avoided.

Abstract: This invention relates to an oil retaining structure of a spindle, wherein the outer peripheral surface of the spindle is provided with a first oil groove extending spirally along a clockwise direction and a second oil groove extending spirally along a counterclockwise direction. The first oil groove and the second oil groove across each other so as to form a plurality of collecting points. In operation, the oil film formed on the outer peripheral surface of the spindle will collect in the two oil grooves slowly, and the lubricating oil in the two oil grooves will bump into each other at the collecting points and then diffuse. As a result, an interior cycle is formed, which not only prevents the leaking of the lubricating oil but also makes the lubricating oil distribute evenly on the surface of the spindle.

Abstract: A time-division method for playing multi-channel voice signals is provided to improve voice qualities of the multi-channel voice signals. The first feature of the present invention is that after time-division sampling, the voice signals can be directly sent to a subsequent voice generator without being demodulated beforehand. The second feature is that the ratio of a specific voice signal to a synthesized voice can be easily adjusted by changing the numbers of channels occupied by the specific voice. Consequently, the adjusting circuitry can be significantly simplified.
