  • Publication number: 20200141762
    Abstract: This invention describes a small sized precision displacement sensor at sub-micron accuracy level with a cost of a fraction of those of existing commercial devices. The basic concept of the new sensor system is to apply a mechanical mechanism to magnify a sub-micron displacement to be measured by about 100 times so that the magnified displacement becomes within the measurement range of a low cost sensor such as a Hall sensor.

  • Patent number: 9383502
    Abstract: A backlight module including a light guide plate, a light conversion layer, a light source, and a reflecting surface is provided. The light guide plate has a light emitting surface, a back surface, a first side, and a second side. The light emitting surface is opposite to the back surface, and the first side and the second side are connected between the light emitting surface and the back surface. The light conversion layer is disposed on the light emitting surface. The light source is disposed at the first side. The reflecting surface is located at the second side. An included angle between the reflecting surface and an extending direction of the light emitting surface is an acute angle. A light beam emitted by the light source enters the light guide plate through the first side, and is reflected by the reflecting surface after being transmitted through the light guide plate.

  • Patent number: 7146885
    Abstract: Disclosed is a sectionless length adjustment mechanism for the shank of a tool (e.g., screwdriver) and for releasably locking the shank in any one of a plurality of positions relative to the handle. In one embodiment the mechanism comprises a sleeve having a front flared end, a spring anchored in the sleeve, a shell including two opposite bars on its surface, and a nut secured to the sleeve. Pulling the shank forward will move the bars outward forward along the flared end to expand the spring. Pushing the shank rearward will move the bars inward rearward along the flared end to compress the spring. Stopping sliding will lockingly engage the shank. Loosening the nut will move the shell forward and expand the spring until the shank is free to slide with the bars disposed at a mouth of the flared end and disengaged from the shank.
