  • Publication number: 20150031965
    Abstract: A method for monitoring physiological parameters associated with a subject using a hand held device is described herein. In an implementation, the method includes obtaining a plurality of sample photoplethysmographic (PPG) features associated with a sample subject, from a video of a body part of the sample subject. From among the plurality of sample PPG features, at least one relevant sample PPG feature associated with the physiological parameter, is selected based on a ground truth value of the physiological parameter for the subject. Further, based on the at least one relevant sample PPG feature and the ground truth value of the physiological parameter, a mathematical model indicative of a correlation between the relevant sample PPG feature and the physiological parameter, is determined. The mathematical model can be deployed for monitoring the physiological parameter in real time.

  • Publication number: 20110055229
    Abstract: An improved system and method for generating a valuation of online sessions on a website following a keyword search. The revenue generated for online sessions of users for pairs of keyword/referrer may be calculated from activities performed on the website during the online sessions and may be added to a sum representing the session value for the pair of keyword/referrer on the website. In an embodiment, the revenue opportunity of the pairs of keyword/referrer for a website may be estimated by multiplying the session value by the difference of a total count of clicks for multiple websites on search results by a referrer for the keyword and a count of clicks for the website on search results by a referrer for the keyword. The pairs of keyword/referrer may be ranked for the website by the estimated revenue opportunity, and then applied to optimize monetization of online content.

  • Patent number: 7152033
    Abstract: A method for multi-modal data fusion (100), a multi-modal system data fusion system (10) and module (24) that in use operates by receiving segments (125) of multi-modal data associated respectively with a modalitiy. Initiating (130) a dynamically variable wait period after one of the segments is received is then performed. The dynamically variable wait period has a duration determined from data fusion timing statistics of the system (10). A waiting (140) for reception of any further segments during the dynamically variable wait period is then effected and thereafter a fusing (145) of the segments received provides fused data that is sent (160) to a dialog manager (25).

  • Publication number: 20040083277
    Abstract: A method of designing a network for an Internet Service Provider (ISP) is taught. The ISP provides routers that handle predetermined traffic demands and that are connected by links. An ordered sequence of (source-destination) pairs of routers is obtained. A particular (source-destination) pair and a minimum capacity on each potential link for the predicted traffic demands on the selected (source-destination) pair are selected. The differential cost of the link is then found, followed by a determination of the least-cost path for the selected (source-destination) pair. The current capacity and current cost of the network are then updated. The process repeats for all (source-destination) pairs in the ordered sequence. Least-cost paths can be determined using the Bellman-Ford method. The output of the basic method can be further refined by the Link Removal Heuristic (LRH) method, and/or a Flow Removal Heuristic (FRH) method.

  • Publication number: 20030214908
    Abstract: A network device that is inserted in the path of traffic in a packet network, and the associated procedures and controller algorithms for monitoring the performance of aggregates of short lived Transmission Control Protocol (TCP) Connections flowing over a bottleneck link and dynamically managing their performance. TCP operates by allowing a certain window of data to be outstanding between the source and the receiver of each transfer and if many transfers attempt to share the network, congestion occurs, thus reducing the transmission rate of ongoing transfers. The method and apparatus aim at the performance of an aggregate of short-lived connections and hence measure only the RTT (Round Trip Time) for the aggregate and determine a window for the aggregate. By setting a target performance for the entire aggregate a measurement is made over the aggregate to determine the current performance level for each value of control eg. A RD (Random Drop) probability, or a value of MWA (Modified window Advertisement).

  • Publication number: 20030214938
    Abstract: The Internet has evolved to a stage where it is expected to support transfer of not only elastic traffic but also real-time traffic with delay, jitter and loss guarantees. Upon the arrival of a request it is necessary to find a path through the network that has sufficient capacity—this is referred to as ‘routing’. It is essential to set up Virtual Paths through a network of routers. Such Virtual Paths are called Label switched Paths (LPs) in MPLS terminology. The arrived request for ingress-egress pair (S,D)1 must be routed along a single (unsplit) path in such a way that the minimum unsplit flow between all other ingress-egress pairs is maximized; here all other ingress-egress pairs have traffic flowing simultaneously. Thus explaining the name Maximum Minimum Additional Flow Routing Algorithm (MMAFRA).

  • Patent number: 6597662
    Abstract: Fairness is provided among network sessions contending for available bit rate (ABR) service in an asynchronous transfer mode network by determining congestion information on a per port basis. ABR cells are monitored to determine which rate information per outgoing port based on ABR cells leaving a switch. Using the ABR per port rate, the available capacity, and the input rate to output queues, a link congestion parameter (LCP) is determined. Resource Management (RM) cells traveling through the switch are monitored to determine whether the new LCP is lower than the explicit rate (ER) field in RM cell. If the new LCP is lower, the new LCP is stuffed into the RM cell. When the sender receives the LCP value, the sender output rate is adjusted based on the LCP. Because LCP is determined based on per port traffic flow, fairness is provided among session competing for available ABR capacity.
