Two-wire controlling and monitoring system for irrigation of localized areas of soil

A two-wire controlling and monitoring system for in particular irrigation of localized areas of soil according to a aspect of the invention comprises a water pipeline, a first plurality of controllable irrigation valves, a second plurality of field sensors measuring specific irrigation parameters, and a third plurality of localized irrigation control units. The third plurality of localized irrigation control units each comprises a sensor decoder connected to a specific field sensor of the second plurality of field sensors and/or a line decoder connected to a specific controllable irrigation valve of the first plurality of controllable irrigation valves. The two-wire controlling and monitoring system further comprises a controller and power supply unit having a set of schedules of instructions and supplying power by applying a first alternating DC voltage signal to a two-wire cable interconnecting the controller and power supply unit and the third plurality of localized irrigation control units. The two-wire cable provides the power from the controller and power supply unit to each of the third plurality of localized irrigation control units. The controller and power supply unit transmits the schedules of instructions to the third plurality of localized irrigation control units through the two-wire cable and receives the specific irrigation parameters from the third plurality of localized irrigation control units through the two-wire cable.

An optical coupler, the optical coupler being usable with a first optical fibre and a second optical fibre. The second optical fibre defines a second fibre coupling section and a second fibre transmitting section extending from the second fibre coupling section. The second fibre coupling section defines a radially outwardmost peripheral surface, the radially outwardmost peripheral surface defining a peripheral surface coupling portion. The optical coupler includes a coupler first end section and a substantially opposed coupler second end section, the coupler first end section defining a first coupling surface. The optical coupler defines a second coupling surface extending along the coupler first and second end sections. The first coupling surface is optically couplable with the first optical fibre and the second coupling surface is positionable so as to extend substantially parallel to the peripheral surface coupling portion and to be optically coupled with the peripheral surface coupling portion. The optical coupler has optical and geometrical properties such that substantially all the light guided to the first coupling surface by the first optical fibre is directed towards the second coupling surface and into the second optical fibre through the peripheral surface coupling portion so as to be guided into the second fibre coupling section for transmission into the second fibre transmitting portion.

An HVDC transmission system including a rectifier station and an inverter station each having a series connection of at least two converters. A by-pass DC breaker is connected in parallel with each converter. A control device is adapted to deblock a blocked converter by starting to control the converter at high delay angle and gradually decreasing the delay angle until substantially all DC current flows through the converter and to then control the by-pass breaker to open at substantially zero current, and to stop the operation of a converter by controlling the converter at gradually increasing delay angle until the voltage across the converter is substantially zero and to then control the converter to be blocked by firing a by-pass pair thereof and to then control the by-pass breaker to close for taking over all the DC current when the voltage between a neutral bus and a pole of a transmission line between the stations is to be increased and reduced, respectively.

Wireless method and apparatus for detecting damage in ceramic body armor

A wireless damage detector for ceramic armor plates includes an interrogator and a body armor ceramic plate. The interrogator includes an inductive primary coil having a resonant frequency. The plate includes a corresponding inductive secondary coil adapted to cooperate with the primary coil when the interrogator is positioned in an interrogation position wirelessly adjacent the plate. When in the interrogation position, the primary and secondary coils are inductively coupled, that is, form an inductive coupling, when the primary coil is energized at the resonant frequency. The plate includes at least one self-contained frangible continuity circuit electrically connected to the secondary coil. The inductive coupling induces an electrical current flow in the continuity circuit when the circuit is undamaged. A detector cooperates with the primary and secondary coils when the interrogator is in the interrogation position. The detector detects the inductive coupling. An indicator cooperates with the detector.

Integrated phase-shift power control transmitter for use with implantable device and method for use of the same

Systems and methods for efficiently transmitting power using a high frequency (e.g., RF) telemetry transmitter are provided. The telemetry transmitter may include a fixed clock source (which may provide a fixed clock signal), telemetry phase shift circuitry (which may include switching circuitry and phase shifting circuitry), and a push-pull network. The telemetry phase shift circuitry generates a phase shifted clock signal that is phase shifted with respect to the fixed clock signal. The fixed and phase shifted clock signals may drive the switching circuitry to produce a high frequency signal that is passed through the push-pull network. The power or magnitude of the high frequency signal is based on the phase delay between the fixed clock signal and the phase shifted clock signal.

The electrodes are disposed in such a way as to support a formation of an electric discharge between the adjacent electrodes, between the electrode adjacent to the first end of the insulating core and to the high voltage conductor or to said coupling means, and between the electrode adjacent to the second end of the insulating core and the metal fastening element attached to the tower. The insulator is provided with means for compensating the reduction of the insulator creepage distance caused by the multi-electrode system. The electric power line using the insulator of this type does not require any lightning arresters.
