    摘要: Extensions exited from electrodes of an electroscan probe, allowing for operation in a wide range of pipe sizes, particularly large diameter pipes, by extending the maximum effective distance of the electric fields generated by the probe. The extensions preferably extend radially from each of the electrodes, and are sized to bring tips of the extensions close to the pipe wall. The extensions can be joined by lanyards to assist in keeping them spaced apart. At least some extensions preferably have bulbous tips, preferably at least partially formed of non-conductive material to keep adjacent extensions from touching each other, especially extensions coupled to different electrodes. The extensions, in one embodiment, are threaded into collars adjacent to each electrode and selected to have a length appropriate for the pipe diameter.

    摘要: An apparatus and method wherein the apparatus comprises: a deformable substrate;a curved support structure; at least one support configured to space the curved support structure from the substrate so that when the deformable substrate is deformed the curved support structure is not deformed in the same way; and a capacitive sensor comprising a protruding electrode capacitively coupled to an overlaying electrode;wherein the protruding electrode protrudes from a side of the curved support structure.

    摘要: A monitoring device is for a block of building material. The monitoring device may include an electric supply line configured to be buried in the block of building material and having a flexible main cable, and flexible jumper cables coupled to the flexible main cable and extending outwardly. The monitoring device may include sensor devices configured to be buried in the block of building material and coupled to respective ones of the flexible jumper cables. Each sensor device may include a primary inductor coupled to the electric supply line at a position based upon peaks of a stationary waveform when the electric supply line is alternating current (AC) powered, and a monitoring circuit. The monitoring circuit may include an integrated sensor, and a secondary inductor magnetically coupled to the primary inductor and configured to supply the integrated sensor, and communicate through the electric supply line.

    摘要: A device includes at least one antenna, a power supply that generates a voltage using electrical energy contained in a first radio frequency (RF) signal generated by an RF scanner, at least two ports to which respective ends of at least one electrical conductor are attached, an impedance meter to which the at least two ports are conductively linked and a transmission controller configured to communicate to the RF scanner, via the antenna, a second RF signal containing data indicating the measured electrical impedance. The impedance meter and the transmission controller are powered by the voltage generated by the power supply using the electrical energy contained in the first RF signal generated by the RF scanner. The device can be configured to be embedded into at least one structural material of a physical structure, or embedded into a structural wrap configured to be attached to the physical structure.
