摘要： Some embodiments of the present invention provide a system that charges a lithium-ion battery. During operation, the system monitors: a current through the battery, a voltage of the battery, and a temperature of the battery. Next, the system uses the monitored current, voltage and temperature to control a charging process for the battery. In some embodiments, controlling the charging process involves: inferring electrode lithium surface concentrations for the battery from the monitored current, voltage and temperature; and applying the charging current and/or the charging voltage in a manner that maintains the inferred electrode lithium surface concentrations for the battery within set limits.

摘要： Methods and apparatuses to perform calibration of imprecise sensors for power monitoring in a data-processing system are described. The system includes a load coupled to one or more sensors. An electronic load changes a first input signal through one or more sensors by a predetermined amount. A difference in an output signal from the one or more sensors in response to the changing is obtained. The output signal is measured and sampled. A distribution of samples of the output signal is determined. The estimated parameters of the distribution that most likely to explain actual data are determined. Next, a transfer function of the one or more sensors is determined based on the estimated parameters. The input signal through the load is accurately predicted using the transfer function of the one or more sensors to monitor the power usage by the load.

摘要： A system that determines power consumption on an IC chip. The system includes a test structure located within the IC chip variations which includes one or more gates which receives power from a power source, wherein each gate has a different drive strength, and wherein the output of each gate is coupled to a load through a corresponding switch. The system also includes a current-measuring mechanism coupled to the power supply which measures the current consumed by the gates. When a specific switch is activated, the output of a corresponding gate is coupled to the load, thereby causing the corresponding gate to drive the load. The current consumed by the corresponding gate is measured by the current measuring mechanism. The measured current can be used to determine the power consumption of the corresponding gate driving the load.

摘要： A system and method for reducing reflections in a transmission line and for recovering energy from the load in the transmission during the process. At least three drive signal levels are utilized. The transition from the second level to the third level during a rising transition and the transition from the second level to the first level during a falling transition is timed to coincide with the arrival of the reflected signal from the immediately-preceding transition. A capacitor is advantageously used as the source for the intermediate drive signal levels and advantageously facilitates energy recovery and conservation.

摘要： One embodiment of the present invention provides a system that facilitates temporarily increasing the operating frequency of an electronic circuit, such as a computer system, beyond a maximum sustainable operating frequency. Upon receiving a request to operate at a higher frequency, the system determines the thermal energy level of a cooling system for the circuit. If the thermal energy level is below a threshold level for the thermal capacity of the cooling system, the system increases the operating frequency of the circuit to a frequency that is greater than the maximum sustainable operating frequency for a period of limited duration. This period of limited duration is short enough to ensure that a temperature increase, caused by increasing the operating frequency, does not raise the operating temperature of the circuit above a maximum operating temperature.

摘要： A power source, inductor and clamping device coupled to generate substantially sinusoidal drive pulses. The power source has an output capacitance. The inductor is connected to the power source and to the load to be driven. In combination with the inductor, the output capacitance of the power source and the input capacitance of the load to be driven create a resonant circuit which generates a stream of substantially sinusoidal pulses. A clamping device is connected to the inductor and prevents the stream of pulses which are driving the load from exceeding a clamping level. In one preferred embodiment, a complementary set of clamping devices and inductors are used to generate a complementary set of pulse streams.
