  • Patent number: 8483111
    Abstract: A mesh node of an infrastructure wireless local area network ‘WLAN’ is coupled to a battery which is coupled to a device that is able to harness energy from a source of renewable energy. Energy management of the mesh node includes conducting simulations of a system comprising the mesh node, the device, and the battery in its current state of charge, determining an admissible load for the mesh node from the simulations, and withholding communication services by the mesh node for one or more periods of time a cumulative duration of which is related to power consumption of the mesh node when handling the admissible load. The simulations involve meteorological data related to the source of renewable energy in the vicinity of the mesh node.

  • Patent number: 8451728
    Abstract: A method is presented for adapting the packet size for VoIP communications, determined on-the-fly by the total network delay inherent at the time of packet transmission. If network delays are small relative to the maximum permissible latency for VoIP communications, the payload size per packet may be increased to maximize efficiency for the transmitted call. Alternatively, if network delays are large, the payload size per packet may be decreased in order to assure that the perceived quality of the transmitted call is acceptable.

  • Patent number: 8265038
    Abstract: Techniques for use in a network processing component is for initially establishing, via a gateway, a voice call between a mobile device which operates in a wireless network and a destination device. A first connection leg of the voice call is to be established between the mobile device and a conference room of the gateway. The technique involves sending to the gateway a request message for establishing a second connection leg between the network processing component and the destination device, and then subsequently sending to the gateway a re-routing message for re-routing the second connection leg from the network processing component to the conference room. This causes a voice call having the first and the second connection legs to be initially established between the mobile device and the destination device via the gateway.

  • Patent number: 8249602
    Abstract: If a handoff by a mobile station currently associated with a particular access point is probable, then the particular access point sends an activation alert to one or more other access points.

  • Publication number: 20120135437
    Abstract: Novel solid-phase biosensors that utilize ink jet printing of biocompatible sol-gel based inks to create sensor strips are reported herein. Biomolecules and other reagents useful in bioassays to detect, for example, pathogenic microorganisms or toxic substances, are immobilized on a substrate, which can be paper based, by layering these substances between two layers of biomolecule compatible sol gel. The sol gel precursor solutions and solutions of the assay reagents are printed from separate nozzles in a layered approach which avoids clogging of the nozzles by the pre-mature gelling of the sol gel precursor solution. In certain embodiments of the application, a capture agent is used to concentrate a compound to be detected in specific areas on the substrate to facilitate detection.
