Abstract: A throttle control method for a mobile device include collecting input data, generating a first set of user experience indices according to the input data, and checking whether a user experience index of the first set of user experience indices satisfies a UEI threshold. The input data includes common information data, current configuration data and a plurality of throttle control parameters. Each user experience index of the first set of user experience indices is corresponding to at least one of throttle control parameter of the plurality of throttle control parameters.

Abstract: A tank valve for a lavatory has a body having a plug with a hollow. A flange is formed on a top edge of the plug. A pair of arms is formed on the flange and extends outwards. An upper ring made of a metal is mounted on a top surface of the flange. A lower ring made of a metal is mounted on a bottom surface of the flange. When a user releases a handle, the valve is immediately pivoted downwards to close a water outlet. Thus, a flow-out capacity of water can be controlled by a time of holding a handle, and a lot of water can be saved.

Abstract: A safety device for a blender has a press movably mounted on top of the handle and having two first extensions selectively extending into the two holes in the handle and a sliding block selectively engaged by the two first extensions and movably received in the handle. The sliding block has two second extensions formed on a bottom of the sliding block to correspond to two holes in the base of the blender. The movement of the press forces the sliding block to move accordingly, such that movement of the two second extensions forces a first contacting plate which is connected to a motor to engage with a second contacting plate which is connected to a power source to complete a circuit of the blender so that the motor is able to drive the blade to rotate.

Abstract: A single ended sense amplifier that not only preserves the high speed feature of the ordinary .vertline.V.sub.TP .vertline., the threshold voltage of a PMOS transistor, but also eliminates the current leakage problem of conventional designs. The single-ended sense amplifier uses seven transistors and one phase clock instead of eleven transistors and two phase clocks as used in the prior art.
