  • Patent number: 7902854
    Abstract: Devices that couple to high voltage transmission lines obtain power themselves using the body capacitance of an element of the devices. The devices generate a comparatively lower voltage from the current flowing between the high voltage line and the element of the device that generates the body capacitance. The devices can be used to operate sensors that monitor the transmission lines or parameters of the power distribution system, such as current, line temperature, vibration, and the like. The devices can also be used as indicators, such as aircraft warning lights, information signs, etc. In addition, the devices can operate as RF transmission/reception or repeater devices, radar devices, mesh networking nodes, video/audio surveillance, sound emitting devices for scaring animals, drones that traverse the power line, etc. Because the devices operate in response to line voltage rather than current, the devices are reliable even in low current conditions.

  • Publication number: 20110015540
    Abstract: A method for measuring an impedance of a body includes the steps of electrically coupling first and second electrodes to the body and electrically biasing a variable frequency relaxation oscillator. The oscillator has both a positive resistive feedback network and a negative feedback network which includes the electrodes. The method further includes a step of measuring the period of oscillation of the variable frequency oscillator. The measured period of oscillation is indicative of the impedance of the body.

  • Patent number: 7761910
    Abstract: A power management architecture for an electrical power distribution system, or portion thereof, is disclosed. The architecture includes multiple intelligent electronic devices (“IED's”) distributed throughout the power distribution system to manage the flow and consumption of power from the system. The IED's are linked via a network to back-end servers. Security mechanisms are further provided which protect and otherwise ensure the authenticity of communications transmitted via the network in furtherance of the management of the distribution and consumption of electrical power by the architecture. In particular, public key cryptography is employed to identify components of the architecture and provide for secure communication of power management data among those components. Further, certificates and certificate authorities are utilized to further ensure integrity of the security mechanism.

  • Publication number: 20100164749
    Abstract: A system and methods for automatically configuring a monitoring device that is attachable to a network coupled to a data collection system. The network has associated network parameters. The monitoring device is coupled to an energy distribution system. The monitoring device measures a characteristic of energy supplied by the energy distribution system and stores data representative of the measured characteristics. A first network communications link is automatically established between the monitoring device and the network, and a host server is contacted to identify network parameters including an address of the data collection system. A second network communications link is automatically established between the monitoring device and the data collection system based on the address of the data collection system. Nameplate and configuration information associated with the monitoring device is communicated from the monitoring device over the network to the data collection system.

  • Patent number: 7734380
    Abstract: A power management architecture for an electrical power distribution system, or portion thereof, is disclosed. The architecture includes multiple intelligent electronic devices (“IED's”) distributed throughout the power distribution system to manage the flow and consumption of power from the system using real time communications. Power management application software and/or hardware components operate on the IED's and the back-end servers and inter-operate via the network to implement a power management application. The architecture provides a scalable and cost effective framework of hardware and software upon which such power management applications can operate to manage the distribution and consumption of electrical power by one or more utilities/suppliers and/or customers which provide and utilize the power distribution system.
