摘要:
A keyboard for a handheld device comprises a plurality of side-keys and a main keyboard. The side-keys are configured at one side(s) and/or back of the device and used for changing layout of the main keyboard and operated by one hand holding the device. The main keyboard is used for inputting characters/commands and operated by another hand. Some or all of the side-keys can also be re-used as mouse buttons together with a touch screen of the device being re-used as a touch pad for a mouse. Some or all of the side-keys are operated by means of releasing a finger holding a side-key first and then using the finger to press down or touch the side-key to hold it again. This method operating a side-key can also be used for other key/buttons such as mouse buttons of a touch mouse, a touch-pad mouse, etc. The main keyboard can further comprise a physical keyboard and a mapping keyboard configured on a touch screen of the device to realize much more keys by means of simultaneously pressing down and releasing two or more keys of the physical keyboard. A current layout of the physical keyboard is mapped to the mapping keyboard.

A system for determining the position of an underground sonde transmitter is disclosed. In some embodiments, the system measures a set of complex electromagnetic field magnitude and phase strengths at one or more positions while traversing a target sonde path at any angle using one or more electromagnetic coil sensors, models a set of expected complex electromagnetic strengths of a hypothetical sonde at the positions for one or more of the electromagnetic coil sensors, the set of expected electromagnetic field values corresponding to a model for the target sonde, and estimates parameters related to the target sonde based on the residual error between the measured set of complex electromagnetic field values and the modeled set of expected complex electromagnetic field strengths. A final estimated parameter set is determined after the residual error has converged to a minimum tolerance to indicate the sonde transmitter position.

A mounting apparatus includes a chassis, a bracket, and two resilient plates. The chassis includes two opposite sidewalls. A protrusion and a hook protrude from an inner surface of each sidewall. The bracket includes a fixing plate for mounting a number of fans, and two end plates. Each end plate defines a first slot, a second slot, a first notch communicating with a bottom of the first slot, and a second notch communicating with a bottom of the second slot. The resilient plates are mounted to inner surfaces of the end plates. Each resilient plate defines a hooking hole overlapping one of the second slots. The protrusions extend through the first notches and engage in the first slots. The hooks extend through the second notches and engage in the second slots and the hooking holes, to lock the bracket to the chassis.

A motor includes a base, a stator, a rotor, a circuit board and a heat-conducting insulator. The base includes a cooling plate. The stator is coupled to the base. The rotor is rotatably coupled to the base and aligned with the stator. The circuit board is received in the base and electrically connected to the stator. The heat-conducting insulator is disposed between the cooling plate and the circuit board, and abuts with the cooling plate and one face of the circuit board.

A fixing apparatus includes an elongated base and a fixing member fixed to a bottom of a fan. The base defines a number of pairs of latching holes spaced in a longitudinal direction of the base. Two pairs of latching feet protrude from a bottom surface of the fixing member to extend through two pairs of the latching holes and engage with a bottom of the base. A hook extends from the fixing member to engage with a side of the base. The fixing member can fix the fan to different places of the base.
