A method for reducing harmonic distortions and switching losses in a power factor correction circuit of a quasi-resonant voltage converter, wherein using data derived from the sensing a voltage impressed on the switching device in the power converter, a multitude of event times can be calculated that will align the timings of the drive circuitry of the power converter to those of the natural resonance transitions of reactive elements of the converter. An over-sampling of the voltage impressed on the switching device voltage allows accurate sensing of a âzero-currentâ cross-over condition in an inductance of the converter.

A device for managing health data provides a first housing portion including a data storage system that stores health data and a second housing portion including a data communications element. The data communications element provides data communications between the data storage system and a processing device that processes the health data according to a data-management software. The first housing portion and the second housing portion are connected by a cable that communicates signals between the data communications element and other components in the first housing portion. Another device for managing health data provides a first housing portion including a health data management system and a data communications element that provides data communications between the health data management system and an external processing device. The second housing portion is removably coupled to the first housing portion, and includes at least one component used by the health data management system.

The present invention is directed to a system and method for delivery of encoding video data over a data network such as an IP network. In addition to having a server capable of sending multiple layers of data into the data network, the system comprises adaptive nodes located intermediate the server and clients located downstream of the adaptive node where these clients may be receivers and/or other adaptive nodes. Receivers and adaptive nodes may be capable of analyzing network capacity by perceiving network congestion conditions of the data network at that device and dynamically changing the channel subscriptions to which the receiver and/or the adaptive node have subscribed based on the perceived network congestion conditions. It is emphasized that this abstract is provided to comply with the rules requiring an abstract which will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure. It is submitted with the understanding that it will not be used to interpret or limit the scope of meaning of the claims.

A system and method is provided to facilitate the transmission of scalable coded video over IP networks. A proposed pre-processing method is disclosed, referred to as multi-track hinting, efficiently structures layered video into a flexible format so that it can be easily streamed over packet-switching networks in accordance with changing network conditions, complexity constraints and user preferences. A general purpose MPEG server, without major modification, is capable of automatically using multiple channels (i.e., RTP connections), thereby providing the streaming system the flexibility to adapt to changing network conditions, complexity constraints and user preferences by adjusting the number of scalable layers to be transmitted. Accordingly, the multi-track hinting method extends the functions of standard Internet streaming protocols (RTSP, SDP) to enable flexible adaptation.

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 () as a separate stream from the media data stream (). 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.

A circular buffer, i.e., a chain of buffers forming a circle, is provided for managing packet loss detection in Internet streaming. The detection latency is determined by the size of the buffer chain, which can be dynamically adapted to network conditions and application requirements. The present invention can achieve reasonable detection accuracy.

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.

This invention provides a system and method to dynamically adapt a wireless link retry limit in real-time according to channel conditions and workload intensity in order to maximize MAC throughput and minimize packet loss. In wireless local area networks (WLANs), such as IEEE 802.11b or a, packets can get lost due to either link error or interface queue overflow. Retry is deployed by a wireless link as a link error protection mechanism to reduce packet loss due to link error. However, an improper configuration of this retry limit (such as too high) may cause more packet loss due to queue overflow than link error. The retry-limit adaptation system and method of this invention strikes a balance between queue drops and link losses. Consequently, it achieves much better network performance in terms of a significant reduction of overall packet loss when compared with situations where the retry limit is statically configured, as recommended by the current standard. For video applications, this dynamic adaptation can be configured in such a way that the video quality for a particular network condition is optimized.
