  • Publication number: 20140023635
    Abstract: The invention provides with means to predict, in subjects affected by type-2-diabetes (T2D), the probability of developing complications related to the disease. The invention involves (1) identification of genetic features such as single nucleotide polymorphisms (SNPs) for the establishment of a patient profile that can be used for prediction of complications associated with T2D. Signature profiles comprising a combination of SNPs which have greater predictive value for prognosticating particular types of complications, such as, stroke, myocardial infarction and kidney complications associated with T2D are further described. Compositions and kits that can be used with a set of complementary phenotypic markers to evaluate the risk for an individual affected by T2D to develop complications related to the disease and to evaluate the likelihood that an individual affected by type 2 diabetes type will benefit from treatments that collectively aim to reduce the risk of developing such complications.

  • Publication number: 20070268826
    Abstract: A flow control method and system including an algorithm for deciding to transmit an arriving packet into a processing queue or to discard it, or, in the case of instructions or packets that must not be discarded, a similar method and system for deciding at a service event to transmit an instruction or packet into a processing queue or to skip the service event. The transmit probability is increased or decreased in consideration of minimum and maximum limits for each flow, aggregate limits for sets of flows, relative priority among flows, queue occupancy, and rate of change of queue occupancy. The effects include protection of flows below their minimum rates, correction of flows above their maximum rates, and, for flows between minimum and maximum rates, reduction of constituent flows of an aggregate that is above its aggregate maximum. Practice of the invention results in low queue occupancy during steady congestion.

  • Patent number: 6393341
    Abstract: An interface layer and method is provided that permits applications, without modification, to operate with any type of meter. The interface comprises an abstraction layer and library or repository of descriptions specific to each meter type. The abstraction layer provides the capability to communicate with any meter through a variety of applications. Upon receiving an application request, the abstraction layer retrieves the description for the particular meter type from the repository and processes the request. In this manner, only one data representation is needed for applications to communicate with a wide variety of meters.

    Abstract: A drive system comprises a brushless multi-phase motor which is supplied with power by way of an inverter including thyristors which are fired by a firing network. The firing network is supplied with information relative to the position of the rotor of the motor, by means of a transducer and this information flows by way of a logic network. Also provided is a current sensing device, a signal from which is passed through a control network to the logic circuit, and the logic circuit acts to modify the signals applied to the inverter in the event that the current flowing in one of the d.c. supply lines to the inverter exceeds a predetermined value for more than a predetermined length of time.

  • Patent number: 3967184
    Abstract: An electrical inverter comprises positive and negative supply lines across which is connected a first series circuit including the anode-cathode path of a first thyristor and the anode-cathode path of a second thyristor. A second series circuit bridges the supply lines and includes a pair of capacitors. In addition a commutating circuit is provided for the first and second thyristors, and this includes a transformer having a secondary winding connected between a point intermediate the first and second thyristors, and the capacitors of the second series circuit, and the primary winding of the transformer is connected in a series circuit, one end of which is connected to the point intermediate the first and second thyristors. The arrangement is such that when the commutating circuit is operated, current flow in the primary and secondary windings of the transformer acts to reduce the current flowing in the conducting thyristor to zero.
