A patch antenna for operation within a high temperature environment. The patent antenna typically includes an antenna radiating element, a housing and a microwave transmission medium, such as a high temperature microwave cable. The antenna radiating element typically comprises a metallization (or solid metal) element in contact with a dielectric element. The antenna radiating element can include a dielectric window comprising a flame spray coating or a solid dielectric material placed in front of the radiating element.

A card connector includes an insulating housing defining a receiving chamber and an inserting chamber connected with the receiving chamber, electrical terminals assembled in the insulating housing, and a shielding shell enclosing the insulating housing. Two receiving fillisters are opened in two inner sides of two side walls forming at two opposite sides of the receiving chamber. Two restraining members each has a base strip disposed in the receiving fillister, and an elastic arm inclined inward into the receiving chamber. The elastic arms are pressed into the receiving fillisters when a SIM card is inserted in the receiving chamber. In the process of inserting a micro SIM card into the card connector, the elastic arms resist against two opposite side edges of the micro SIM card to guide a rear of the micro SIM card to be smoothly inserted into the inserting chamber.

A hot swap fan includes a fan frame and a terminal seat. A corner of the fan frame has an accommodating space and two connecting parts. The connecting parts are disposed adjacent to the accommodating space. The terminal seat has a seat body and two coupling elements. The coupling elements are disposed at two sides of the seat body and disposed corresponding to the connecting parts, respectively, so that the seat body can be disposed at the accommodating space. The diameters of the connecting parts are larger than those of the coupling elements so that the terminal base can be slightly movable in the accommodating space.

A novel image sensor structure formed on a substrate of a first conductivity type includes a photosensitive device of a second conductivity type and a surface pinning layer of the first conductivity type. A trench isolation region is formed adjacent to the photosensitive device pinning layer. The structure includes a dopant region comprising material of the first conductivity type formed along a sidewall of the isolation region that is adapted to electrically couple the pinning layer to the substrate. The corresponding method facilitates an angled ion implantation of dopant material in the isolation region sidewall by first fabricating the photoresist layer and reducing its size by removing a corner, or a corner portion thereof, which may block the angled implant material. To facilitate the angled implant to the sidewall edge past resist block masks, two methods are proposed: 1) a spacer type etch of the imaged photoresist; or, 2) a corner sputter process of the imaged photoresist.
