Abstract: A method for a mouse is provided. The mouse includes a housing, a timing unit. A container is secured in the housing. The container is full of insulated liquid. A sphere suspends in the liquid. First sensors and second sensors are attached to the container. Each first sensors is charged, each second sensors is uncharged. The first sensors are spaced from each other by one second sensor. When any adjacent first sensor and second sensor are simultaneously contacted by the sphere, the contacted second sensor is thus charged. The method includes: determining whether any second sensor is charged; generating a position signal, controlling the timing unit to time within the period the any second sensor being charged; determining the movement direction of the a cursor; determining the movement distance of the cursor; and generating cursor control signal for controlling movement of the cursor.

Abstract: The subject invention relates to a scratch-resistant optical film, which comprises: (a) a transparent substrate having a first surface and a second surface; (b) a diffusion layer on the first surface of the substrate, which has a convex-concave structure and is comprised of a first hard coat layer comprising organic particles; (c) a scratch-resistant layer on the second surface of the substrate, which is comprised of a second hard coat layer; wherein the organic particles in the first hard coat layer are formed from a polyacrylate resin which comprises at least one multi-functional acrylate monomer as polymerization units, said multi-functional acrylate monomer being in an amount from 30 to 70 wt % based on the total weight of the monomer used, and wherein the organic particles have a single mean particle size and have a particle size distribution in the range within about ±5% of the mean particle size.

Abstract: A liquid optical lens, including a transparent container, an elastic membrane, a first liquid and a second liquid, is provided. The transparent container is divided into a first chamber and a second chamber by the elastic membrane. The first liquid fills the first chamber. The second liquid fills the second chamber. The curvature of the elastic membrane is regulated by changing the volume ratio between the first liquid and the second liquid, so as to adjust the focal length of the liquid optical lens. Moreover, a liquid optical lens module including the above liquid optical lens and a volume adjustment mechanism is also provided. The focal length of the liquid optical lens can be precisely adjusted by using the volume adjustment mechanism.
