摘要： For a peer-to-peer call in an ad hoc wireless network, a wireless device performs discovery of a target wireless device, performs authentication of the target wireless device and generates a session key (e.g., using a pre-shared key or a certificate provisioned on the wireless device), forms an ad hoc wireless network with the target wireless device, and communicates peer-to-peer with the target wireless device via the ad hoc wireless network. The wireless device may perform discovery with a list of identifiers for wireless devices designated to communicate with this wireless device. The wireless device may derive a service set identifier (SSID) used to identify the ad hoc wireless network based on its user-specific identifier (e.g., its phone number) and/or a user-specific identifier for the target wireless device. The wireless device may also performs IP address discovery using the user-specific identifier for the target wireless device.

摘要： Hybrid fiber/coax networks employ the existing cable plant used for cable TV and transmit data signals in a frequency bandwidth above that which is used for cable TV. As this cable plant was deployed in a tree and branch topology, data transmissions may be susceptible to noise, variable transmission loss and frequency dispersion, particularly in the upstream direction. Further, due to the tree and branch topology, homes at the far end of the network experience much greater loss than do the homes that are near to the headend/ONU. The present system, which uses point-to-point data links between intelligent network elements located in the feeder/distribution network to provide reliable, secure, bi-directional broadband access. Digital signals, or messages, are terminated at the intelligent network elements, switched and regenerated for transmission across additional upstream or downstream data links as needed to connect a home to a headend or router. Messages indicative of an end user routing ID (RID) are identified and the information extracted for user with successive messages. In this manner, the data links are made over relatively short runs of coax cable, which can provide greater bandwidth than the typical end-to-end feeder/distribution connection between a home and the headend or optical network unit.

摘要： Disclosed herein are platform- and device-independent systems and methods for serializing and deserializing data. A method of serializing data stored in a data structure comprises generating a data structure descriptor representing information about a memory layout of the data structure and serializing the stored data based upon the data structure descriptor. The data structure descriptor may include a layout array, including a memory offset and a size corresponding to each member of the data structure. A method of processing serially received data for storage in a data structure comprises receiving a serial data stream, allocating memory for storing the data based upon a data structure descriptor, and deserializing the data stream based upon the data structure descriptor. The data structure descriptor may include a layout array, including a memory offset and a size corresponding to each member of the data structure.

摘要： The present invention generally relates to vacuum pressure swing adsorption (VPSA) processes and apparatus to recover carbon dioxide having a purity of approximately ≧80 mole percent from streams containing at least carbon dioxide and hydrogen (e.g., syngas). The feed to the CO2 VPSA can be at super ambient pressure. The CO2 VPSA unit produces two streams, a H2-enriched stream and a CO2 product stream. The process cycle steps are selected such that there is minimal or no hydrogen losses from the process. The recovered CO2 can be further upgraded, sequestered or used in applications such as enhanced oil recovery (EOR).
