摘要: Each of a plurality electronic circuit devices fixed to a structural component of a physical structure can be scanned a first time, using a radio frequency (RF) scanner to receive, from each of the plurality of electronic circuit devices, first data indicating a first measured electrical impedance of a respective conductor connected to the electronic circuit device and an identifier assigned to the electronic circuit device. For each of the plurality of electronic circuit devices, the first data indicating the first measured electrical impedance and the identifier assigned to the electronic circuit device can be stored to a first memory. The first data indicating the first measured electrical impedance and the identifier for each of the electronic devices can form a baseline measurement of the electronic circuit devices.

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 electronic device may have a flexible display such as an organic light-emitting diode display. A strain sensing resistor may be formed on a bent tail portion of the flexible display to gather strain measurements. Resistance measurement circuitry in a display driver integrated circuit may make resistance measurements on the strain sensing resistor and a temperature compensation resistor to measure strain. A crack detection line may be formed from an elongated pair of traces that are coupled at their ends to form a loop. The crack detection line may run along a peripheral edge of the flexible display. Crack detection circuitry may monitor the resistance of the crack detection line to detect cracks. The crack detection circuitry may include switches that adjust the length of the crack detection line and thereby allow resistances to be measured for different segments of the line.

摘要: A carbon nanofiber aggregate (CNFA) system and method provides self-sensing capabilities that can be used to detect strain, moisture, and temperature changes. The CNFA may include cement, aggregate, silica fume, high-range water reducer (HRWR), and/or carbon nanofibers. The metal meshes in the CNFA may be utilized to monitor the electric properties of the CNFA to detect strain, moisture, and temperature changes. The CNFA may be embedded in concrete structures to allow detection of strain, moisture, and temperature changes that may cause damage to structures. Several metal meshes may be embedded in the CNFA.

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.
