Abstract: A silicon photonics optical transceiver device includes a silicon photonics optical module and a heat conducting housing that accommodates the silicon photonic optical module therein. The heat conducting housing has an inner surface formed with a first heat dissipation portion that wraps around and is in contact with transmitter optical sub-assemblies of the silicon photonics optical module to realize thermal conduction, and a second heat dissipation portion that is in contact with a digital signal processor of the silicon photonics optical module to realize thermal conduction.

Abstract: An optical tracking device includes an optical detection module and a target component. The optical detection module includes an optical receiver. The target component includes a light penetrating body with at least one mark and movably disposed adjacent to the optical detection module. The target component allows an illumination beam penetrating into the light penetrating body, so that the optical detection module acquires a detection image containing a pattern of the mark for tracking a relative movement between the target component and the optical detection module.

Abstract: A zipper includes a slide and two tapes each having a row of helically arranged teeth sewn to a lateral edge thereof. The slide includes two opposed boards whose first ends are connected by a central guide. A second end of at least one of the boards includes two flanges respectively extending along two lateral edges thereof toward the other board, defining a substantially Y-shaped channel between the boards and the central guide. A flange extension extends from each flange toward the first end of the board, with a distance between each flange extension and the central guide being the same as a width of each tooth of the zipper. At least one of the flange extensions extends to a level aligned with or beyond a maximum width of an inner end of the central guide and includes an end edge with a stop corner.

Abstract: A convenience high-brightness breakdown alarm lamp of car comprises a base, a circuit unit, a light source, and a lampshade. The circuit unit is disposed in the base. The light source is electrically connected to the circuit unit so that the required electricity can be inputted to the light source. The lampshade is made of transparent material, and is connected with the base. The light source is received in the lampshade. The breakdown alarm lamp has a high brightness and a better alarming effect, and can be placed conveniently.

Abstract: A brassiere with replaceable cups mainly comprises cups placed on the breast and a girdle band holding the brassiere in place over the user's back and chest. The cup frame comprises two pieces of symmetrical cups and three pieces of joint elements for holding the cups in place and forming a buckling element in the central area of the cup frame. Thus, the cups of the cup frame can be replaced by joining and splitting the three pieces of joint elements for better comfort. In the mean time, the girdle band can be used even after the cups are replaced to reduce the cost for purchasing the brassieres.

Abstract: Apparatus for Mandarin Chinese speech recognition by using initial/final phoneme similarity vector, for improving the Chinese speech recognition accuracy and downsizing the needed memory is provided.
