Abstract: A portable electronic device includes a first housing, a second housing detachably latched to the first housing through a latching tab, and a releasing mechanism. The releasing mechanism includes a button, an elastic member, and a shaft. The button surrounds the shaft and is rotatably assembled to the first housing by the shaft. The elastic member is coiled around the shaft and elastically resists the button to apply an elastic force to enable the button resisting the first housing. When the button rotates about the shaft under a pressure overcoming the elastic force, the latching tab is pushed to release the latching tab and the second housing.

Abstract: A card-loading assembly for loading a chip card in an electronic device is provided. The electronic device includes a main body, a circuit board received in the main body, and an entrance defined in the main body. The card-loading assembly includes a positioning frame and a tray. The positioning frame is secured on the circuit board and defines a sliding recess. The tray includes a support portion and an extending portion extending from the support portion. The extending portion is made of dielectric material. The support portion and the extending portion cooperatively define a receiving space for receiving the chip card. The tray is received in the main body through the entrance. The support portion is slidably received in the sliding recess. The extending portion is positioned between the circuit board and the entrance.

Abstract: A chip card holder includes a tray and a protecting member. The tray includes a receiving portion and a handle portion. The receiving portion is configured to receive a chip card. The handle portion is positioned at a side of the receiving portion. The protecting member is sleeved on the receiving portion and resists the handle portion. The protecting member is made of elastic material so as to prevent outside contamination from entering the chip card holder.

Abstract: Methods for determining the likelihood of colorectal cancer (CRC) recurrence in a subject that involve measuring the expression level of two or more micro ribonucleic acids (miRNAs) in a biological sample comprising CRC tumor cells from said subject and using the normalized, measured expression levels to determine the likelihood of colorectal cancer recurrence for said subject. In the methods, the normalized expression levels of specific miRNAs are weighted by their contribution to CRC recurrence to calculate the likelihood of CRC recurrence. Kits for measuring the expression level of specific miRNAs that can be used in determining the likelihood of CRC recurrence are also provided.

Abstract: A portable electronic device includes a housing and an antenna module detachably assembled to the housing. The housing defines at least one latching hole. The antenna module includes a base and an antenna attached to the base. The base includes at least one latching member. The base is received in the housing. The at least one latching member engages with the at least one latching hole to detachably assemble the base and the antenna to the housing.

Abstract: A key with efficiency of depth and scattered light has a key body and a light-shading layer. The key body has a key surface and a key back surface opposite to the key surface, and a pattern is formed on the key surface. The light-shading layer is partially light transmissible and covers over the key back surface. The light-shading layer has a first transparent pattern area, which is located corresponding to the patter. The area of first transparent pattern area is greater than or equal to that of the pattern.

Abstract: An edge-coupled photodetector, especially a compound semiconductor edge-coupled photodetectors, has a light funnel integrated right in front of the coupling aperture for enhancing the optical coupling efficiency. The light funnel is formed utilizing either a wet etched, crystallographically defined semiconductor slope or a dry etched, resist-profile-defined semiconductor slope covered by the planarized dielectrics. The funnel internals can be partially or fully metallized for total mirror reflection. The lightwave entering the funnel and propagating along the optical axis converges through mirror reflection or total internal reflection. Through such an invention, the edge-coupled photodetector can have both high operation speed and high quantum efficiency with enlarged alignment tolerance.

Abstract: A self-aligned fabrication method utilizes dielectric planarization process for fabricating ridge waveguide semiconductor lasers. The dielectric planarization process starts with depositing a thick dielectric film onto the ridge-structured semiconductor wafer surface, and then the resulting corrugated dielectric surface is polished into a flat surface in a self-terminated manner. This dielectric flat surface is able to uniformly expose its semiconductor ridge tops by an overall etch-back process.
