| 20090085546 | Fast Transient Step Load Response in a Power Converter - A method of controlling a power converter having at least one switching device for supplying an output voltage and a load current to a load is disclosed. The method includes sensing the output voltage and sensing the load current. The method further includes controlling a duty cycle of the switching device according to the sensed output voltage and a voltage control loop when a rate of change of the load current does not exceed a threshold level. The method also includes adjusting the duty cycle of the switching device set by the voltage control loop when the rate of change of the load current exceeds the threshold level. | 04-02-2009 |
| 20100033143 | Switching power converter and controller - A switching power converter includes an input for receiving an input voltage, an output for providing an output voltage, a controller, and a power circuit coupled between the input and the output and including at least one switch. The controller is configured to determine a duty cycle for the switch to regulate the output voltage and control the switch with a PWM drive signal having an on-time and an off-time. The PWM drive signal has a constant frequency and a duty cycle equal to the determined duty cycle when the determined duty cycle is greater than or equal to a minimum duty cycle. The PWM drive signal has a variable frequency and a duty cycle equal to the minimum duty cycle when the determined duty cycle is less than the minimum duty cycle. | 02-11-2010 |

| 20100121157 | WIRELESS SENSOR RESIDENT ANNOTATIONS - A high percentage of preventable medical errors occur due to poor communication during the period when patient care is handed from one caregiver to another. Electronic annotations from patient specific body sensor networks are created and classified according to the caregiver and the urgency of the annotation to ensure that no information goes unnoticed during the transfer of care.
