Patent number: 8159938Abstract: Communication in a broadcast-only distributed wireless network of nodes is provided. Each of the nodes of the network uses a repeated communication frame with an idle period and a TDMA schedule for active communication. The active TDMA schedule of at least some of the nodes in the network are aligned and synchronized. The distributed network does not require a central node for coordinating the TDMA schedules of another node or for synchronizing the communication frames. TDMA slots of the TDMA schedule are used for broadcasting and receiving messages. A node broadcasts a message without the use of an address of the receiving node. Communication frames having dynamic properties, such as communication frame length and start time, TDMA schedule position and length, and idle period position and length, are provided. Distributed functions for nodes to search for and synchronize with other nodes are also provided.Type: GrantFiled: June 23, 2008Date of Patent: April 17, 2012Assignee: C.H.e.S.S.

Patent number: 8130964Abstract: A method and system for encrypting a first piece of information M to be sent by a sender [100] to a receiver [110] allows both sender and receiver to compute a secret message key using identity-based information and a bilinear map. In a one embodiment, the sender [100] computes an identity-based encryption key from an identifier ID associated with the receiver [110]. The identifier ID may include various types of information such as the receiver's e-mail address, a receiver credential, a message identifier, or a date. The sender uses a bilinear map and the encryption key to compute a secret message key gIDr, which is then used to encrypt a message M, producing ciphertext V to be sent from the sender [100] to the receiver [110] together with an element rP. An identity-based decryption key dID is computed by a private key generator [120] based on the ID associated with the receiver and a secret master key s.Type: GrantFiled: October 28, 2009Date of Patent: March 6, 2012Assignees: The Board of Trustees of the Leland Stanford Junior University, The Regents of the University of California, DavisInventors: Dan Boneh, Matthew Franklin

Patent number: 8125641Abstract: A method and apparatus for convolving spectroscopic data with certain phase information for practicing phase-compensated sensitivity-enhanced spectroscopy (PCSES). PCSES uses a beam of radiation in a polarization state PSp from a source emitting at a plurality of wavelengths, and places in the beam a compensator capable of altering polarization state PSp by applying a delimited phase shift ? between two orthogonal polarization axes of the radiation to restrict a finely-vibrating spectrum. A sample disposed in the beam after the compensator generates a response beam by reflection, transmission or even both. A polarization state PSa of the response beam is passed to a detector to determine a spectrum of the response beam. A first spectrum is collected when polarization states PSp, PSa and the compensator are in a first polarization-altering configuration and a second spectrum is collected when polarization states PSp, PSa and the compensator are in a second polarization-altering configuration.Type: GrantFiled: March 27, 2009Date of Patent: February 28, 2012Assignee: n&k Technology, Inc.Inventor: Guoguang Li

Patent number: 8101080Abstract: An advanced water treatment method processes a continuous flow of water in a sequence of stages including pre-filtering to remove solids, conditioning to adjust pH, blending with a recycled dense microalgae culture, and passing the resulting mixture through an enclosed, environmentally-controlled photobioreactor where nutrients, PCB's, trace metals and other pollutants and regulated compounds are taken up by the algae. The flow from the PBR is separated using cross-flow filtration to produce a treated water flow and a dense microalgae flow that is recycled to the blending stage upstream. Thus, whereas the algae is recycled, the water entering the system is treated by flowing sequentially through the stages of the system, without any recycling or repetition of treatment stages.Type: GrantFiled: June 22, 2011Date of Patent: January 24, 2012Assignee: AlgEvolve, LLCInventors: Terry S.
