摘要： A system and method is provided for providing integrated over-current protection in a switching power supply. In one embodiment, a switching power supply could comprise a gate drive circuit operative to receive a pulse-width modulated (PWM) signal and to drive at least one power field effect transistor (FET) between alternating activated and deactivated states based on a pulse-width of the PWM signal. The switching power supply could also comprise a current sense circuit operative to measure a current associated with the at least one power FET during the activated state. The switching power supply could also comprise a first over-current protection circuit providing a first adjustment to the PWM signal in response to the current being substantially between a first threshold and a second threshold. The second threshold could be greater than the first threshold. The switching power supply could further comprise a second over-current protection circuit providing a second adjustment to the PWM signal in response to the current being substantially greater than the second threshold.

摘要： A system and method provides a realistic architecture and specifies the protocols that are necessary for carrying out adaptive and efficient protection, thereby allowing applications to dynamically switch between different protection strategies. Protection is uniquely achieved by providing the protection track (206, 208, 210) as a separate stream from the media data stream (202, 204). In this manner, changing the protection data can change the protection level or strategy, but the protection procedures remain the same. Further, the method uses Real-time Transport protocol (RTSP) instead of Internet Group Management protocol (IGMP) which can achieve faster protection and provide more flexibility to applications.

摘要： A power supply comprising a flyback converter and a controller is disclosed. The flyback converter drives a load when electrically coupled to an alternating current power source. The controller controls a soft switching during each switching time period of the flyback converter. Upon an initial switching time period, the controller determines each acceptable switching frequency for the subsequent switching time periods and selects one of the acceptable switching frequencies for soft switching the flyback converter over one or more switching time periods during a constant load.

摘要： A communication system comprises a set of specialized backend servers 100 and groups of terminals (210, 220) connected through the Internet. Users of the communication system can make video calls and share text messages, images and video clips through the terminals (210, 220). The terminals in this system are organized into private terminal groups 200 of varying sizes. Each group has only one controller terminal 210 and one or more display terminals 220. Both types of terminals provide an easy-to-use graphic user interface for the user to access the communication services provided by the system. Communication and information sharing between any display terminals must be pre-authorized by their controllers. This communication system, while ensuring security and privacy, addresses the needs of caregiver groups that include caregiver professionals, family members and care receivers, to facilitate private conference calls, information sharing and caring activity coordination.

摘要： The present invention relates to a method and an apparatus for estimating a clock skew. The method comprises: obtaining a basic clock skew of each clock tree in the circuit; judging whether two units are in a same clock domain; if they are in different clock domains, estimating the clock skew between units to be a larger one of basic clock skews of the clock trees corresponding to these two unit; if these two units are in the same clock domain, further judging whether they are in a same hierarchical logic block; if they are in different hierarchical logic blocks, estimating the clock skew between units to be the basic clock skew of the clock tree of these two units plus additional clock skew caused by different hierarchical logic blocks. The apparatus is corresponding to the method. With the method and apparatus, the clock skew in the circuit can be estimated more accurately, which improves the efficiency of circuit design.

摘要： Embodiments provide methods and systems wherein analyte concentration readings taken over a first period of time are collected and processed to determine one or more analyte concentration averages. The methods include collecting samples with a measurement system (e.g., a Blood Glucose Meter) over a first period of time, dividing the first period of time into smaller time increments, and calculating an average analyte concentration based on first sub-averages obtained from each of the smaller time increments. Systems for carrying out the analyte concentration averages are described, as are other aspects.

摘要： A receiver-driven streaming method is provided. The method includes receiving an original coded video stream from a transmitter 102 at a receiver 104. An available bit rate is measured at the receiver 104. A request for a different coded video stream and a switching stream is sent from the receiver 104 to the transmitter 102 based on the available bit rate. The requested switching stream is received from the transmitter 102 at the receiver 104. The requested coded video stream is received from the transmitter 102 at the receiver 104. According to one embodiment, switching streams 132a-132f are stored separately from coded video streams 130a-130c, and each switching stream 132a-132f and coded video stream 130a-130c is stored in a separate track from each other. In this way, switching streams 132a-132f maybe generated offline. Also, the receiver 104 controls the streams provided by the transmitter 102 by requesting specific switching streams 132a-132f and coded video streams 130a-103c.

摘要： A so-called “Virtual Clock” with varying frequency is provided for used by a multimedia streaming server to adapt its transmission rate dynamically to changing network conditions. The “Virtual Clock” system and method of the present invention compensates for a potential limitation of the Internet Real-time Transmission Protocol (RTP), that stamps every packet it delivers with a timestamp and expects the server using this timestamp to schedule the transmission of this particular packet accordingly. Consequently, the transmission rate is pre-determined by the encoded multimedia content when RPT is used. Using the “Virtual Clock” of the present invention, the streaming server has a mechanism to overcome this RTP limitation and can conduct transmission rate adaptation in a way that can balance the bandwidth requirement of the content with the bandwidth availability of the network.
