  • Publication number: 20150124792
    Abstract: Methods, systems, and devices are described for Wi-Fi peer-to-peer (P2P) communications. A seeker user equipment (UE) may identify a desired service to be provided via Wi-Fi P2P communication. The seeker UE may broadcast a probe that identifies the desired service. An advertiser UE may receive the probe from the seeker UE. The probe identifies a desired service for the seeker UE that is to be provided via Wi-Fi P2P communication. The advertiser UE may transmit a probe response to the seeker UE only when it is determined that the advertiser UE is capable of providing the identified desired service.

  • Patent number: 8995833
    Abstract: In an automatically switched optical network operating according to a wavelength plan, the wavelengths are assigned to an optical path based on availability, performance and SRS wavelength coupling reduction. First, the wavelengths are grouped in static bins based on their reach versus cost performance, and each bin assumes a ?Q of a middle wavelength. Then, the bins are moved into subsets of dynamic bins, constructed using bin constraints that account for the particulars of the respective optical path. The path is characterized taking into account the wavelength currently accessing at the end nodes, and the wavelength tandeming through the end nodes. Wavelength selection starts with the bins that satisfy the maximum number of constraints, and the wavelengths are checked sequentially against wavelength constraints; relaxed constraints are also applied when it is not possible to exactly satisfy one or more constraints.

  • Publication number: 20150086900
    Abstract: A fuel cell stack assembly comprises a plurality of fuel cells in a stack, the stack defining two opposing parallel end faces. An end plate is disposed at each opposing end face of the stack. Each end plate defines a compression surface adjacent to and in compressive relationship with a respective one of the two opposing parallel end faces. A coupling mechanism is attached to the end plates to thereby maintain the fuel cells in the stack under compression. At least one, preferably both, of the end plates comprise a preformed element defining the compression surface, the preformed element being configured with a predetermined curvature such that the compression surface is a convex surface when the preformed element is not under load whereas, under the application of the load to maintain the fuel cells under compression, flexure of the preformed element between elements of the coupling mechanism causes the compression surface to become a substantially planar surface.
