  • Patent number: 8134128
    Abstract: A method of analyzing a remotely-located object includes the step of illuminating at least a portion of a targeted object with electromagnetic radiation to induce a phase transformation in the targeted object, wherein the phase transformation produces an emitter plasma, which emits terahertz radiation. The method also includes the step of ionizing a volume of an ambient gas to produce a sensor plasma by focusing an optical probe beam in the volume and the step of detecting an optical component of resultant radiation produced from an interaction of the focused optical probe beam and the terahertz radiation in the sensor plasma. Detecting an optical component of the resultant radiation emitted by the sensor plasma facilitates detection of a characteristic fingerprint of the targeted object imposed onto the terahertz radiation produced as a result of the induced phase transformation.

  • Patent number: 8131365
    Abstract: A remaining charge capacity of a battery having an initial charge capacity is monitored. The battery powers a remote implantable medical device (IMD) that includes an active state, during which the remote IMD performs at least one function, and an inactive state, during which the remote IMD performs no functions. An active state charge consumption is computed based on stored parameters associated with an operational charge consumption for each function, and an inactive state charge consumption is computed based on a leakage current associated with the inactive state and a time the remote IMD is in the inactive state. The active state charge consumption and inactive state charge consumption are subtracted from the initial charge capacity to determine the remaining charge capacity.

  • Publication number: 20120009971
    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: 20110157940
    Abstract: Various exemplary embodiments relate to a power factor corrector for low loads and a related method. The power factor corrector raises power factor at low loads or high mains voltages by having the a greater amount of current delivered to the load during the falling time of the absolute value of the mains AC voltage than during the applicable rising time. Various embodiments achieve this by increasing the switch-on time of a control switch during the falling time so that the majority of the switch-on time during a mains period occurs during the falling time. This may involve using a timing voltage increasing over a period within each half mains cycle to increase the switch-on time of conversion cycles in the falling time. This may also involve shifting the power conversion in time domain during each half mains cycle so that a majority of the time occurs during the falling time. Various embodiments may employ both methods.
