  • Publication number: 20100054169
    Abstract: A method for allocating resources in a wireless network includes establishing one or more links. The method also includes the following iterative steps: allocating a first number of slots to the relay links; dividing the first number of slots among the relay links; determining a representative relay data rate indicative of a data rate provided by one of the relay links for one of the multi-hop access links; allocating the second number of slots to the multi-hop access links; dividing the second number of slots among the multi-hop access links; determining the effective multi-hop data rate based on the minimum of the representative relay link data rate and the multi-hop data rate; allocating the third number of slots to the single-hop access links; dividing the third number of slots among the single-hop access links; and upon the single-hop data rate being approximately equal to the effective multi-hop data rate, provisioning the first, second and third number of slots.

  • Publication number: 20100054171
    Abstract: A method for selecting an access link in a multi-hop relay network includes determining a first effective spectrum efficiency value of a first connection between an endpoint and a base station. The first effective spectrum efficiency value is indicative of the spectrum efficiency from the endpoint to the base station when the first connection is used. The method also includes determining a second effective spectrum efficiency value of a second connection between the endpoint and the base station via a relay station. The second effective spectrum efficiency value is indicative of the spectrum efficiency from the endpoint to the base station when the second connection is used. The method also includes comparing the first and second effective spectrum efficiency values. The method further includes establishing a connection using one of the first or second connections based on the comparison of the first and second effective spectrum efficiency values.

  • Publication number: 20100054170
    Abstract: A method for allocating resources in a multi-hop relay network includes establishing one or more relay links, single-hop access links, and multi-hop access links. The method also includes iteratively repeating the following steps until a single-hop data rate is approximately equal to a multi-hop data rate: allocating a first number of slots to the multi-hop access links; dividing the first number of slots among the multi-hop access links; allocating a second number of slots to the relay links; allocating a third number of slots to the single-hop access links; dividing the third number of slots among the single-hop access links; and comparing the single-hop data rate to the multi-hop data rate. The method also includes, upon the single-hop data rate being approximately equal to the multi-hop data rate, provisioning the first number of slots to each of the multi-hop access links, the second number of slots to each of the relay links, and the third number of slots to each of the single-hop access links.

  • Publication number: 20100046376
    Abstract: A method for balancing network load includes determining an initial capacity of a wireless network comprising a plurality of endpoints coupled to a plurality of different types of access stations. The access stations comprise one or more relay stations and at least one base station. The method also includes identifying one or more endpoints that would increase capacity of the wireless network if switched to a different access station. The method further comprises tentatively switching the identified endpoints from their current access station to a different access station. The method additionally includes determining if the capacity of the wireless network is increased from the initial capacity by the tentative switch and, upon the capacity of the wireless network increasing, switching the identified endpoints from their current access station to a different access station.

  • Patent number: 7491545
    Abstract: A highly selective and sensitive of a carbonic anhydrase-based method for measurement of zinc ion by an excitation ratiometric format based on resonance energy transfer: i.e., where the zinc ion level is transduced as the ratio of fluorescence intensities excited at two different excitation wavelengths, is provided. The method can be used very well in a fluorescence microscopy format. A detection limit of about 10 pM in zinc buffered systems, a ten to one thousand-fold improvement on the Fura indicators (which respond to Ca and Mg as well), and a one hundred thousand-fold improvement on the recently described FuraZin-1 is achieved.

  • Patent number: 7186424
    Abstract: The present invention is a multifunctional nutrient supplement and a process for creating the supplement. The supplement comprises a mixture of lecithin, ginkgo biloba and wheat germ oil. The supplement is made with a five step formation process. The first step of the process uses CO2 supercritical extraction to remove cholesterol, glyceride and fatty acids from an egg yolk. Wheat germ oil is then obtained from dried wheat germ using CO2 supercritical extraction. Gingko biloba is then removed from ginkgo leaves using CO2 supercritical extraction. The egg yolk/lecithin from the first extraction is then combined with the wheat germ oil from the second extraction. Ethanol is then added to the mixture of lecithin and wheat germ oil and low temperature vacuum distilled to create a lecithin and wheat germ oil mixture. The ginkgo biloba extract is then added to the lecithin/wheat germ oil mixture to create the nutrient supplement.
