Abstract:
A motion sensing device includes a housing defining a chamber that includes a number of sidewalls. A number of movable members are connected to the sidewalls and able to move toward the sidewalls. Each movable member includes a number of conductive grooves opposing the sidewalls and having a resistance layer. A number of conductive spring members are respectively fixed to the sidewalls and each include a free end movably received in one conductive groove. An inertial weight is movably received in a space defined by the movable members. When the motion sensing device is jerked, the inertial weight moves and is able to apply a pushing force to one of the movable members, causing one of the movable members to move and causing two of the free ends in the same conductive groove to move toward each other.

Abstract:
The present disclosure provides an electronic device with a remote control earphone electrically connected to the main body of the device. The remote control earphone includes seven sensing units, which are substantially arranged in a “8” shape. Sensing signal generated by each sensing unit in response to a touch from the user includes an identification code for identifying itself. The remote control earphone transmits the generated sensing signal to the main body. The main body includes a cache unit to store at least one identification code corresponding to the sensing signal, a storage unit to store the relationship between the identification codes and numbers the identification codes corresponding to, and a processing unit to determine which one of the numbers is input according to the at least one identification code and the relationship.

The printed circuit board is fixed parallelly to the bottom plate. The port connector includes an outer angled plate having a first wall, a second wall, and first pins and second pins. The first wall is attached to the bottom plate and defines first ports. The second wall is attached to the side plate and defines second ports. Each of the first pins is retained within one of the first ports and contacting the printed circuit board. Each of the second pins is retained within one of the second ports and contacting the printed circuit board.
Abstract:
A shield case is configured for supporting a memory card. The shield case includes a recessed portion, and a first edge, a second edge, and a third edge arranged around the recessed portion. The first edge forms a first support plate. The second edge forms a second support plate. The first support plate and the second support plate cooperatively support the memory card.
Abstract:
A portable electronic device includes a housing, a rotation sensor, and a processor. The rotation sensor includes a supporting plate fixed to the housing, a cylindric carrier, an electron emitting device, a magnet, a number of strip-shaped electrodes, and a detecting device. The cylindric carrier is disposed on the supporting plate and is rotatable relative to the supporting plate. The electron emitting device is disposed on the supporting plate and emits electrons along the center axis of the cylindric carrier. The magnet provides a magnetic field substantially parallel to the supporting plate. The detecting device detects the falling position of the electrons and generates a signal representing the parameters of the rotation of the portable electronic device. The processor receives the signal generated by the detecting device and generates an operating signal for operating the portable electronic device.
