Abstract: A device for monitoring and measuring the electrical and mechanical parameters of a power line conductor. Sensors of the device measure conductor temperature, the angle of inclination of the overhead conductor, current flowing in the conductor, and voltage to ground. The device has a low-power mode in which parameters of the power line conductor are not measured. Upon detecting a change in an electrical or mechanical value of the power line conductor, the device measures parameters of the power line conductor for a predetermined length of time before returning to the low power mode.

Abstract: A power supply extracts electrical power from the electro-magnetic field surrounding a high voltage power conductor and conditions the derived input power to provide a stable power source for instrumentation and communications equipment. The communications controller is a local network router that routes serial data traffic to selected communication devices such as an instrumentation processor, a power supply processor, or a maintenance port controller. The router forwards the data to other communications equipment and forwards data from the communicating equipment to an external network providing substantially simultaneous communications between the external network and the instrumentation processor, power supply processor and maintenance port controller.

Abstract: An apparatus for monitoring and measuring the electrical, thermal and mechanical operating parameters of high voltage power conductors. A toroidal shaped housing, which can be mounted onto an energized conductor, contains all of the necessary electrical instruments to monitor the parameters associated with the conductor. Moreover, the housing includes the processing capability to analyze disturbance and fault events based on these parameters.

Abstract: The combination of a temperature sensor and an inclination sensor or the combination of a temperature sensor and a tension monitor properly positioned in conjunction with an energized electrical conductor produces outputs that are dependent on the conductor's average temperature in real time. A transmitter is used to communicate this information in real time to a central location such that up to optimal or maximum power transmission is feasible through the conductor while maintaining a safe clearance to the ground. This allows for close monitoring of thermal expansion resulting from increased load as well as varying environmental conditions.

Abstract: A UV light source water disinfection system includes a UV light source that is driven or controlled by a ballast. Improved start-up scenarios are provided by use of a separate heating wire around the lamp or employing an inductive-coupled system to provide initial high power requirements. The UV lamp is discontinuously operated in order to extend the life of the system, save energy, and periodically dose standing water to prevent regeneration of undesired microorganisms.

Abstract: A method and apparatus are provided for dynamically allocated multiple slots within a multi-channel multi-carrier transmission system. The slots may be allocated sequentially or non-sequentially. The data transmission rate for each slot remains constant, while multiple slots may be allocated to a single user service. Each carrier signal contains header data regarding all other carriers associated with the transmission system to identify the allocation of slots to user services. In an alternative embodiment, an encoding and transmitting system is provided for transmitting one or more video and audio encoded signals in a time division multiplexed manner along separate channels having fixed bandwidths. Multiple audio channels may be transmitted simultaneously with a related single video channel, and vice versa. The time division multiplexed audio/video signals may be transmitted over a single carrier or over multiple carriers.
