Abstract: In an embodiment, a chemical mechanical planarization (CMP) system includes: a monolithic platen within a platen housing, wherein the monolithic platen is formed of a single piece of material, wherein the monolithic platen includes: a first portion within a first opening, and a second portion within a second opening, wherein the first portion has a different diameter than the second portion; and a polishing fluid delivery module above the monolithic platen, wherein the polishing fluid delivery module is configured to deliver slurry to the monolithic platen during performance of CMP.

Abstract: A light emitting device comprising a light guiding frame and a light source is provided. The light guiding frame has a recess, and an edge of an opening of the recess defines a light-emitting opening. The light guiding frame comprises a first light guiding structure and a second light guiding structure connected to the first light guiding structure. The light source is disposed on a bottom of the recess and has a light-emitting surface. The first light guiding structure is extended along a direction away from the light-emitting surface and the light-emitting opening. The second light guiding structure is extended along a direction away from the light-emitting surface but close to the opening.

Abstract: A lighting device is provided. The lighting device includes an optical reflection plate, a light holder, and at least one light source. The optical reflection plate includes a non-reflective region located in the center of the optical reflection plate, and a plurality of reflection regions surrounding the non-reflective region in sequence. The light holder is located on the non-reflective region of the optical reflection plate and includes a circle side-light concave portion. A light-emitting opening of the side-light concave portion faces to the reflection regions. The light source is located in the side-light concave portion of the light holder. When the light source emits light, the light emitted from the light source is reflected by the reflection regions.

Abstract: A light-guiding element, an illumination module and a laminate lamp apparatus are provided. The light-guiding element comprises an upper reflection member extended along a longitudinal axis direction, and a lower reflection member extended along the longitudinal axis direction thereof and coupled to the upper reflection member. The lower reflection member comprises a first reflective portion with at least a first inclined flat plate, and the upper reflection member comprises a second reflective portion facing towards the first reflective portion. A light placement portion and a light outputting trough are formed between the first reflective portion and the second reflective portion. The light outputting trough is gradually expanded largely according to a direction of being away from the light placement portion.

Abstract: A rotation angle regulating device and a rotatable lamp using the same are provided. Through N passive rotating elements used for regulating the rotation angle, the rotation angle of the active rotating element relative to the fixing element is increased, wherein N is a positive integral equal to or more than 1. In addition, each passive rotating element has a first stopper and a second stopper. The active rotating element, when rotating, drives and makes the passive rotating elements rotating on the fixing element, so that the rotation of the lamp can be stopped at any designated angle through the operations of the first and second stoppers of each passive rotating element.

Abstract: A slave and a master of serial peripheral interface, system thereof and method thereof are provided. The invention saves the read address during the process of data-read in the serial peripheral interface (SPI) and adds a new data-read command so that when the former data address is followed by the next one, the transmission of the read address is ignored by using new read command in order to increase the efficiency of data read in the serial peripheral interface.

Abstract: A method and apparatus for avoiding bi-directional signal fighting of a serial interface is disclosed. The serial peripheral interface includes a clock signal line and a data line. In this method, during normal operation, a first clock signal is received and transformed to output a second clock signal in the clock signal line, wherein the second clock signal has a first duty period. When the output of the data in the data line switches to input, the second clock signal switches to have the second duty period, wherein the second duty period is larger than the first duty period.
