  • Patent number: 8553649
    Abstract: The present invention is directed to a system and method which base stations send informational messages to neighbor base stations when conditions change, so that the neighbor base stations can update its database to keep itself current on the parameters (including availability, traffic load, modulation scheme, etc.) to use in effecting efficient base station to base station handoffs. In one embodiment, the receiving base station marks the time of the received message from a neighbor base station and if a new updated message is not received within a time window then the receiving base station assumes that there is a problem with that neighbor.

  • Publication number: 20130153790
    Abstract: Methods and systems for detecting radiation for example, terahertz radiation, with the aid of acoustic signal generation and detection include: directing an optical beam into a volume of gas; ionizing at least a portion of the volume of gas with the optical beam to produce a plasma; and detecting an acoustic signal produced from an interaction of a radiation wave with the plasma. The methods and systems are particularly adapted for remote detection of chemicals, biological substances, and explosives, among others. The capability of the methods and systems can be enhanced by employing multi-color laser excitation to produce the plasma and varying the time delay between the multi-color pulses.
