Abstract: A method and system for optimizing the behavior of a charger connected to a portable device when the portable device current exceeds the charger current limit. The system includes a configuration module configured to set a maximum current limit and a register-based current limit values. The system further includes a port power switch configured to limit the portable device current, in the event that the portable device current exceeds the maximum current limit value. The port power switch is configures to modify the portable device current to a predetermined constant current value or reset the current to zero based on the relation between the maximum current limit and the register-based current limit value.

Abstract: A system and method are presented for aligning a rotor in a motor. The motor may include the rotor and a plurality of pairs of electromagnets. One or more pairs of electromagnets may be excited at a first excitation level. The one or more pairs of electromagnets may be less than all of the plurality of pairs of electromagnets. The excitation of the one or more pairs of electromagnets may be increased to a second excitation level over a first period of time. The excitation of the one or more pairs of electromagnets may be decreased to a third excitation level over a second period of time. Exciting the one or more pairs of electromagnets, increasing the excitation, and decreasing the excitation may cause the rotor to stop in a known position.

Abstract: An emulation system for charging any arbitrary portable device through a communication port on the portable device. The system includes a receptacle port for communicating with the portable device and a profile database for storing multiple charging profiles. Each charging profile including a set of parameters and at least one exit condition. Further, an emulation module applies a first charging profile to the portable device and monitors the set of parameters associated with the charging profile to identify an associated exit condition. Upon a determination that the exit condition for the first charging profile is met, the emulation module applies a next charging profile to the portable device.

Abstract: A system for measuring a voltage drop between two nodes in an electrical circuit, comprising a switched capacitor integrator (SCI), a comparator and a counter. The SCI alternately (a) captures charge onto a set of sampling capacitors and (b) selectively accumulates/transfers the charge onto a pair of integration capacitors, where the charge includes a first portion that is based on the voltage drop and a second portion that depends on a digital indicator signal. The comparator generates the digital indicator signal based on whether an analog output of the SCI is positive or negative. The counter counts a number of ones occurring in the digital indicator signal during a measurement interval. At the end of the measurement interval, the count value represents a measure of the voltage drop. Knowing the resistance between the two nodes, the voltage drop may be converted into a current measurement.

Abstract: System and method for determining closure of an electronic device. The electronic device may include a top portion and a bottom portion, and may be connecting via a hinge or other closing mechanism. The top portion and/or the bottom portion may include one or more capacitive sensors which provide signals corresponding to physical contact and a controller coupled to the one or more capacitive sensors. The controller may operate to receive the signals from the one or more capacitive sensors, determine if the electronic device has been closed based on the received signals, and initiate a sequence of events corresponding to the closure of the electronic device. The sequence of events may result in the device entering a low power state.

Abstract: A method for transferring data between a host device and an external device is described. The external device has FAT32 file system. The method accepts parameters for an incoming data file from the host device. Further, the method allocates memory blocks for the incoming file data on the external device based on the parameters and indexes the allocated memory blocks on a memory index table to create a file footprint. The method reads the memory index table to identify the file footprint and receives the incoming file data from the host device.
