    Abstract: The present invention discloses a charge control circuit for supplying power from an external power source to a first common node and charging a second common node from the first common node. A regulator circuit is coupled between the external power source and the first common node, and a transistor is coupled between the first common node and the second common node. The present invention detects an operation parameter of the transistor and controls an internal voltage source to generate a non-predetermined voltage difference accordingly. When the sum of the voltage at the second common node and the non-predetermined voltage is equal to or higher than the reference voltage, the voltage at the first common node is regulated to a level higher than the voltage at the second common node, and the transistor is in an optimum conductive state.

    Abstract: Some techniques feature a computer-implemented method for messages associated with a user location. The method involves determining, by a mobile computing device, an estimated geographic location of the mobile computing device. The method includes receiving, at the mobile computing device, one or more messages associated with an area within the estimated geographic location, where the one or more messages include messages posted by users of a system that associates messages that those users posted about the area within the estimated geographic location. The method involves providing, on a display of the mobile computing device, one or more posted message icons that are presented in a layer over a map, where the one or more posted message icons represent the one or more posted messages. In a system, the one or more posted messages may not appear on mobile devices after a predetermined amount of time from their respective postings.

    Abstract: An automatic switch method and apparatus are used to set the output current of a USB by slowly increasing the output current under monitoring the voltage on the USB. If the USB could normally operate until the output current reaches a threshold value, a higher level is set for the output current, otherwise a lower level is set instead. The process may be performed periodically to dynamically determine the output current for the USB.

    Abstract: A power safety system includes a first MOS, a second MOS, a switch and a body controller. The first MOS is connected between a power input and a power output. The second MOSFET is connected between the power output and a charging output. The switch has an end connected to the body of the first MOS, and the opposite end switched between the source and the drain of the first MOS. A body controller controls the switch according to the voltage at the power input and the voltage at the power output, to connect the body of the first MOS to the source or the drain of the first MOS. By switching the switch, the first MOS will have a parasitic diode effective to prevent a reverse current from the power output to the power input.
