Abstract: An encoder applied to a rotatable device including a code disc set, at least one bearing, a bearing housing, a main housing, a sensor and an elastic assembly. The code disc set is disposed on a rotation end of the rotatable device. The bearing is disposed around the rotation end, and the bearing housing is disposed around the bearing. The main housing is connected with a first end of the bearing housing. The sensor is disposed on the main housing and corresponds to the disc wheel set, and there is an interval between the sensor and the code disc set. The elastic assembly is connected with a second end of the bearing housing and a fixing end of the rotatable device. Therefore, the interval between the sensor and the code disc set is maintained to be fixed, and the good position detection performance and stable signals are obtained.

Abstract: A method and apparatus for measuring thickness of a film in a solar cell provides for directing light emitted at multiple emission wavelengths, to a surface of the solar cell. Each emission results in the generation of a responsive photo current. The photo currents are read by a current meter having one contact coupled to a surface of the solar cell and another contact coupled to another surface. The currents associated with each of the different light emissions are identified and the thickness of a film in the solar cell is calculated based on the two currents or associated quantum efficiencies, and associated absorption coefficients. In one embodiment, the film thickness is the thickness of a CdS or other buffer film in a thin film solar cell.

Abstract: A solar cell comprises a back contact layer, an absorber layer on the back contact layer, a buffer layer on the absorber layer, and a front contact layer above the buffer layer. The front contact layer has a first portion and a second portion. The first and second portions of the front contact layer differ from each other in thickness or dopant concentration.

Abstract: A method recognizing dice dots comprises the steps: projecting at least one dice with a plurality of different angle light sources; capturing a plurality of images of the dice according to the projecting times of the light sources on the dice; and recognizing dice dots based on the images through calculation methods. When recognized results obtained through the calculation methods are judged same by the recognizing module the dice dots are confirmed and accepted. If the recognized results done through the calculation methods are different, the dice is rolled anew.

Abstract: An apparatus for recognizing dice dots includes a dice cup to hold at least one dice, and a light source module and a capturing module located in the dice cup. The light source module generates a plurality of light sources to project to the dice. The capturing module captures images of the dice a number of times according to the light sources projection times to generate a plurality of image information. The image information are sent to a recognizing module which stores a plurality of calculation methods to recognize dice dots according to the image information. When recognized results obtained through the calculation methods are judged same by the recognizing module the dice dots are confirmed and accepted. If the recognized results done through the calculation methods are different, the dice is rolled anew.
