The present invention also provides an anti-peep method applicable to the anti-peep display device.

Abstract: A semiconductor device includes a single diffusion break (SDB) structure dividing a fin-shaped structure into a first portion and a second portion, an isolation structure on the SDB structure, a first spacer adjacent to the isolation structure, a metal gate adjacent to the isolation structure, a shallow trench isolation (STI around the fin-shaped structure, and a second isolation structure on the STI. Preferably, a top surface of the first spacer is lower than a top surface of the isolation structure and a bottom surface of the first spacer is lower than a bottom surface of the metal gate.

Abstract: In some examples, a device can include an antenna to emit waves in a radiation pattern having a first beamwidth, a directional radiation control device located in a path of the waves, where the directional radiation control device is to receive the waves from the antenna and is shaped to cause the waves to be directed in a different radiation pattern having a second beamwidth that is larger than the first beamwidth.

Abstract: A portable traffic warning device releasably mounted on the underside of a lift gate of an automobile includes, in combination three elongated members set up in a triangular shape having a triangular hollow therethrough; a support leg pivotably secured to an upper central portion on a rear surface of the elongated members; a plurality of lamps arranged as a triangle on a front surface of the elongated members; and a rechargeable battery and controller mounted on the rear surface of the elongated members, the rechargeable battery and controller being electrically connected to an automotive battery of the automobile; wherein the lamps are controlled by the rechargeable battery and controller to operate in a first mode of continuously emitting light or a second mode of flashing.

Abstract: An electronic device (100) having a speaker (30) located in a sealed and separate speaker enclosure is described. The electronic device includes a housing (20), a circuit board (70), a cover (60), and two connecting bodies (50). The housing includes a cavity (22) defined therein for receiving the speaker. The circuit board is electrically connected to the speaker. The cover has through holes (622) defined thereon and is disposed between the housing and the circuit board. In addition, one end of the connecting bodies connects to the speaker, and the other end of the connecting bodies is configured to resist the circuit board via the through holes to electrically connect the speaker and the circuit board.

Abstract: An electronic device (100) having a speaker (30) located in a sealed and separate speaker enclosure is described. The electronic device includes a housing (20) having a cavity (22) receiving the speaker with at least one conductive post (342), a circuit board (70), and a cover (60) with at least one through hole (622). The cover is disposed between the housing and the circuit board. One end of the conductive post passes through the through holes and electronically connects the speaker to the circuit board.

Abstract: The present invention discloses a cigarette box structure capable of collecting cigarette ashes and cigarette buds, and the cigarette box reserves a collecting space, and includes surfaces a refractory adhesive material enclosed around the collecting space, such that after a smoker lights up a cigarette, the smoker can use the collecting space in the cigarette box to collect cigarette ashes and cigarette buds appropriately or put out a cigarette to avoid cigarette ashes from flying all over the place, dumping cigarette buds anywhere, or causing a fire or a dirty visual effect.
