Abstract: An electronic device includes multi-touch screen and a password input system. The multi-touch screen can detect a sequence of user inputs, each of which involves tapping at least one point thereof. The password input system includes a determining unit, a storing unit, an indexing unit, and an outputting unit. The determining unit can count the numbers of touch point(s) of the user inputs. The storing unit stores a character database which includes a collection of numbers of touch point(s) and a collection of corresponding machine-readable characters. The indexing unit can look up matching machine-readable characters for the user inputs in the character database. The outputting unit can output the matching machine-readable characters sequentially as a password.

Abstract: An electrical connector includes a printed circuit board, a plug fixedly and electrically connected to the printed circuit board, an electromagnetic shielding cover configured for encompassing the printed circuit board, a reinforced frame configured for framing the plug and the electromagnetic shielding cover to the circuit board and, a housing configured for housing the printed circuit board, the plug, the electromagnetic shielding cover and the reinforced frame therein.

Abstract: A heat dissipating assembly capable of being placed between a circuit board and a casing of an electronic device includes a fan assembly and a bracket. The fan assembly is mounted on the circuit board. The fan assembly includes an enclosure defining a chamber and an opening at a side wall thereof, along with a blower received in the chamber. The bracket is located between the fan assembly and the casing of the electronic device. The bracket has a side wall thereof defining a cutout connected with the chamber. The cutout and the opening of the enclosure are defined at two different sides of the heat dissipating assembly.

Abstract: An example embodiment of the present invention may be directed to a method for transmitting a short message using a voice channel. In the example embodiment, a short message may be composed using a first short message service (SMS) device for a set of intended recipients. The first SMS device may identify whether a voice channel exists between the first SMS device and at least one member of the set of intended recipients. The first SMS may then transmit the short message to the at least one member of the set of intended recipients using the voice channel.
