  • Publication number: 20150146521
    Abstract: A method for managing a pool of bandwidth resources available over a communication network as executed by a processor. The method includes receiving a plurality of wholesale bandwidth values requesting bandwidth from the pool of bandwidth resources from a plurality of computing resources associated with the plurality of customers, wherein the wholesale bandwidth values are guaranteed over a predetermined period, and wherein the pool has a maximum capacity. The method includes tracking bandwidth resource usage throughout the predetermined period. The method includes allocating a first portion of available bandwidth from the pool to a first customer based on a reselling rate ratio applicable to the plurality of customers at a particular point in time during the predetermined period. Available bandwidth is generated by purchasing unused bandwidth from the plurality of customers over the predetermined period.

  • Publication number: 20150008971
    Abstract: Disclosed is a noise current compensation circuit. The circuit is provided with two input and output terminals A and B, and two control terminals CON and CONF. The control terminals control a work mode (work state and pre-charge state) of the compensation circuit. The compensation circuit consists of 7 PMOS transistors and 8 NMOS transistors. In the normal work state, by detecting changes of potential change rate of two signal lines in an original circuit, the noise current compensation circuit automatically enables one end of the original circuit that discharges slowly to discharge a signal more slowly, and enables one end of the original circuit that discharges rapidly to discharge a signal more rapidly, thus eliminating the influence of the noise current on the circuit and providing assistance for correct identification of subsequent circuit signals.

  • Publication number: 20140376305
    Abstract: The present invention discloses a circuit for improving process robustness of sub-threshold SRAM memory cells, which serves as an auxiliary circuit for a sub-threshold SRAM memory cell. The output of the circuit is connected to the PMOS tube of the sub-threshold SRAM memory cell and the substrate of a PMOS tube in the circuit. The circuit comprises a detection circuit for threshold voltage of PMOS tube and a differential input and single-ended output amplifier. The circuit changes the substrate voltage of the PMOS tubes in the sub-threshold SRAM memory cell and the substrate voltage of the PMOS tube in the circuit in a self-adapting manner by detecting threshold voltage fluctuations of PMOS tubes and NMOS tubes resulted from process fluctuations and thereby regulate the threshold voltages of the PMOS tubes, so that the threshold voltage of PMOS tubes matches the threshold voltage of NMOS tubes.

  • Patent number: 8346641
    Abstract: In one embodiment, a method includes generating a request of an entity based on a set of attributes provided by an initiating patron of the entity using a processor of an initiator device. The method also includes associating an aggregation environment to the request. The method further includes allocating an initial consideration to the aggregation environment from the initiating patron. In addition, the method includes allocating, to the initial consideration, an additional consideration provided when a different patron contributes the additional consideration to the aggregation environment of the request using a processor of a supporter device. The method also includes allocating the consideration of the initiating patron and the different patron to the aggregation environment of the request to increase a value of the request to the entity in order to increase a possibility of the entity to respond to the request using a processor of an entity device.

  • Patent number: 7848982
    Abstract: A method, apparatus and system of method and system of aggregating consideration associated with a request is disclosed. In one embodiment, a method includes generating a request (e.g., may include a performance request, an article request, a mission and/or an altruistic request) of an entity based on a set of parameters provided by an initiating patron of the entity, allocating an initial consideration to the request from the initiating patron, generating a profile of the request having the initial consideration in a request aggregation environment and allocating, to the initial consideration, an additional consideration provided when a different patron contributes the additional consideration to the request. The method may include determining whether contact information of the entity provided by the initiating patron and the different patron references to a verified contact data and communicating the request to the entity based on the contact information and the verified contact data.
