20080297965 | CONTROL SYSTEM AND METHOD WITH CONSTANT MAXIMUM CURRENT FOR POWER CONVERTER PROTECTION - System and method for protecting a power converter. The system includes a first comparator configured to receive a threshold signal and a first signal and to generate a comparison signal. The first signal is a sum of a second signal and a third signal, and the third signal is associated with an input current for a power converter. Additionally, the system includes a pulse-width-modulation generator configured to receive the comparison signal and generate a modulation signal in response to the comparison signal, and a switch configured to receive the modulation signal and control the input current for the power converter. An amplitude for the first signal becomes larger if an amplitude for the input voltage becomes larger. The second signal is generated by receiving an input voltage for the power converter, converting the received input voltage to a fourth signal, and converting the fourth signal to the second signal. | 12-04-2008 |
20100146065 | METHOD AND APPARATUS FOR REALIZING INSTANT MESSAGING BETWEEN A PLURALITY OF MEMBERS IN AN INSTANT MESSENGER GROUP - The invention provides a technical solution for instant messaging among multiple members of an instant messenger group. An instant messenger group server is independent of an instant messenger server. At least one group identification and a member list of each group identified by the corresponding group identification are prestored in the group server. The instant messenger group server logs in to the instant messenger server as an instant messenger client, using each of said at least one group identification as an instant messenger identification, and receives instant messages sent by an instant messenger client and sends the instant messages respectively to each of the instant messenger clients corresponding to the instant messenger identifications of other members the instant messenger server. Since the instant messenger group server is independent of the instant messenger server, the instant messenger group server can support multiple instant messenger platforms. | 06-10-2010 |
20100165676 | SYSTEM AND METHOD PROVIDING OVER CURRENT AND OVER POWER PROTECTION FOR POWER CONVERTER - System and method for protecting a power converter. A system includes a threshold generator configured to generate a threshold signal, and a first comparator configured to receive the threshold signal and a first signal and to generate a comparison signal. The first signal is associated with an input current for a power converter. Additionally, the system includes a pulse-width-modulation generator configured to receive the comparison signal and generate a modulation signal in response to the comparison signal, and a switch configured to receive the modulation signal and adjust the input current for the power converter. The threshold signal is associated with a threshold magnitude as a function of time. The threshold magnitude increases with time at a first slope during a first period, and the threshold magnitude increases with time at a second slope during a second period. The first slope and the second slope are different. | 07-01-2010 |

20120221348 | IDENTIFYING A DEVIATION DURING CLINICAL PATHWAY EXECUTION - A system and method for identifying a deviation during clinical pathway execution. The system comprises: a clinical pathway storage component configured to store a clinical pathway; a semantic relationship storage component configured to store a semantic relationship between activities; a receiver component configured to receive an activity inputted from a user; and an activity matching component configured to judge, based on the semantic relationship between activities, whether the inputted activity matches the requisite activity defined in the clinical pathway, and if it is determined that the inputted activity does not match the requisite activity defined in the clinical pathway, generate a first clinical pathway execution deviation report, wherein the first clinical pathway execution deviation report indicates that an undefined redundant activity is executed. This permits the precision of identifying deviation during clinical pathway execution to be improved. | 08-30-2012 |
