Abstract: An antenna assembly adapted to be assembled to a desktop computer includes a shielding body and an antenna body. The shielding body includes a first wall, two first shielding walls, and two second shielding walls. The first wall is connected to the two first shielding walls and the two second shielding walls and faces an outside of the desktop computer. The antenna body is at the first wall of the shielding body, and one or more portion of the antenna body is connected to the first shielding wall or the second shielding wall. The antenna body is operated at a frequency range of 2400 MHz and 2500 MHz or between 5150 MHz and 7125 MHz.

Abstract: A fan module comprises a frame, a wire-stopping structure, an impeller and a circuit board. The frame includes a frame wall, a base, a plurality of static blades and a connector. A wire groove formed on an outside of the frame wall to accommodate a wire. The static blades are radially connected to the base and the frame wall. The connector is formed on the outside of the frame wall and extended from one end of the wire groove to the base along one of the static blades. The connector includes a plurality of pins. The wire-stopping board is fixed to the frame wall to cover the wire groove. The impeller is disposed in the frame. The circuit board is disposed in the frame and located on the base. The circuit board includes a plurality of pin holes, and the pin holes are electrically connected to the pins.

Abstract: A fan includes an impeller and a fan frame. The impeller is accommodated within the fan frame. The impeller has a hub and a plurality of blades disposed around the hub. The hub has a top portion and a side wall connected with the top portion. The hub further has a plurality of flexible portions disposed and located on the side wall. The blades are connected with the flexible portions, respectively, so that the blades are connected to the hub.

Abstract: A keyboard arrangement for an electronic device has multiple keys for inputting Chinese characters, multiple of the keys represent multiple combination vowels and all of the keys are arranged in a matrix form. The matrix of the keys are arranged in four key rows including a monosyllabic vowel row and three disyllabic vowel rows. The monosyllabic vowel row includes multiple keys arranged in a row and corresponding respectively to monosyllabic vowel phonetic symbols. Each disyllabic vowel row includes multiple keys arranged in a row and corresponding respectively to disyllabic vowel phonetic symbols those have a same transition vowel phonetic symbol and consonant phonetic symbols. The keys of the disyllabic vowel rows corresponding to a same monosyllabic vowel phonetic symbol are arranged in a column. Accordingly, an inputting method for Chinese characters applied with the keyboard arrangement is easy to learn and use.

Abstract: An isolating diseaseproof and contraceptive hygienic cover including a cover body and a ring member. The cover body is substantially hoof-shaped and has an opening at a middle lower portion thereof. The ring member is coaxially fixedly connected to peripheral wall of the opening. The cover body has a wall radially extending from the opening and rearward inclined. The wall of the cover body has a thickness gradually reduced from the peripheral wall of the opening to outer edge of the cover body. The hygienic cover is sheet-like and has greatly reduced area and volume, so that the manufacturing cost and time thereof are decreased. In use, the present hygienic cover is able to provide more reliable contraceptive and diseaseproof effect and can be more conveniently and quickly put on/taken off in a-simple manner without affecting a sexual activity.
