Abstract:
PURPOSE: A system and a method for measuring horizontal and vertical vibration and deflection of a transmission line are provided to prevent the suspension of power supply and a forest fire by monitoring horizontal and vertical vibration and deflection of a transmission in real time. CONSTITUTION: A system for measuring horizontal and vertical vibration and deflection of a transmission line comprises a target(10), a camera unit(20), a control box(30), a power supply unit(40) and a total station(50). The target comprises a reflective sheet(16) reflecting lightwave projected by the total station. The camera unit takes an image of the target to recognize a mark of the target. The control box calculates the three-dimensional position of the target using a camera lens(21) and measures horizontal and vertical vibration and deflection of a transmission line. The power supply unit supplies power to the control box. The total station measures the location of the target through cable or wireless communication with the control box.
Abstract:
PURPOSE: A no battery moving sensor node is provided to operate a node by without using a separate power source storage. CONSTITUTION: An operation unit(170) includes a sensor, transmitter, and CPU. The sensor senses environment information. The CPU controls a whole operation of the sensor node. A scavenger(110) creates electrical energy by obtaining energy from a surrounding environment. A capacitor(130) is charged by allowing the electrical energy that is created from the scavenger. In case a charged electrical energy is over than a prescribed standard, the capacitor supplies the charged electrical to the operation unit.

Abstract:
A remote control device is provided. The remote control device includes a shell (1) configured with a thermoelectric generation module (3), a central processor (2), a button module (4) and a RF module (5). The thermoelectric generation module (3) is connected with each of the other modules (2, 4 and 5). The central processor (2) is connected with the button module (4) and the RF module (5). The thermoelectric generation module (3) includes an electricity generation unit (31). The electricity generation unit (31) includes two metal sheets (311 and 312) which are made of different materials and form a closed loop circuit via two connection points (A and B). The electricity generation unit (31) is able to generate a thermoelectromotive force based on a temperature difference between the two connection points (A and B), and powers the other modules (2, 4 and 5) by the thermoelectromotive force.
Abstract:
A method, performed by a tag device that is coupled to an electronic device, for initiating a function in the electronic device includes receiving a signal from an interrogator device. The method also includes determining from the signal to initiate a function in the electronic device, and signaling the electronic device to initiate the function.
Abstract:
The invention relates to a switching device (130) for a radio pushbutton (100). The switching device (130) has an energy-converting apparatus (140), a signal-outputting apparatus (160), actuating means (170, 172, 180) and a plurality of coding contacts (155). The switching device (130) is characterised in that the actuating means (170, 172, 180) are designed to contact at least one of the plurality of coding contacts (155) during an actuating process of the switching device (130), in order to provide a coding signal when a first magnitude of an actuating force is present in a coding position and to activate the energy-converting apparatus (140) in order to generate energy when a second magnitude of the actuating force that is greater than the first magnitude is present in an activation position. The signal-outputting apparatus (160) is designed to output a switching signal by radio by using the coding signal and the energy.
