Abstract: A latching mechanism for holding an electronic card on a printed circuit board, includes an insulative fixing device mounted to the printed circuit board and a metallic latching device attached to the fixing device. The fixing device provides the positioning post extending through the positioning hole of the electronic card and the latching device provides a hook section downwardly pressing the electronic card so as to have the electronic card in a parallel relation with the printed circuit board. A card edge connector is provided on the printed circuit board for cooperatively holding the electronic card thereon.

Abstract: A card edge connector (100) comprises an insulative housing (1) defining a central slot (10) with a plurality of contacts (2) by two sides. Two arms (3) are positioned at two opposite ends of the insulative housing. Each arm includes a plastic portion (30) and a metal portion (31) attached to the plastic potion. The plastic portion includes a locking lug (301) and a restraint head (302). The metal portion is retained to the housing and extends inwardly a guidance stud (316) and a stop tag (317) for covering the locking lug and the restraint head respectively, and the stop tag is as high as an upper end of the guidance stud. While a card module is inserted into the central slot in a correct position and rotated downwardly to directly engage and push the guidance studs, the metal portions together with the plastic portions can be deflected outwards so that the card module is secured held.

Abstract: An apparatus includes a microphone to generate a voice signal. The apparatus further includes an adjustable gain circuit coupled to the microphone to selectively apply a gain to the voice signal. In addition the apparatus includes an analog front end circuit coupled to the adjustable gain circuit to transmit the voice signal via a telephone line. Also, the apparatus includes a control circuit coupled to the adjustable gain circuit. The control circuit is operative to detect an average level of energy of the voice signal outside of a voice frequency band. The control circuit is further operative to control, based at least in part on the detected average level of energy, an amount of gain applied to the voice signal by the adjustable gain circuit.
