Abstract: A system includes a first electronic device configured to attach to an industrial machine or one or more areas of an industrial facility. The first electronic device is configured to transmit a signal indicative of a potentially hazardous condition with respect to personnel of the industrial facility. The system also includes a second electronic device communicatively coupled to the first electronic device and configured to attach to a hardhat of the personnel of the industrial facility. The second electronic device is configured to receive the signal from the first electronic device, determine whether a parameter of the signal is above a threshold, and generate an alarm when the parameter of the signal is above the threshold. The alarm is configured to indicate the potentially hazardous condition to the personnel.

Abstract: A wireless actuator circuit configured to actuate a micro electromechanical system (MEMS) switch is provided. The wireless actuator circuit includes a transmitter portion and a receiver portion operatively coupled to the transmitter portion. The transmitter portion includes an oscillator device configured to generate a signal at a determined frequency and a first antenna operatively coupled to the oscillator device to receive a modulated signal. Further, the receiver portion includes a second antenna configured to receive the modulated signal from the transmitter portion, a radio frequency power detector configured to detect the modulated signal and a comparator configured to produce a control signal in response to the modulated signal detected by the radio frequency power detector to toggle the MEMS switch.

Abstract: An inspection system for a metal-reinforced concrete structure is described. The system includes a radio frequency (RF) system configured to be movable with respect to a surface of the concrete structure while transmitting radio signals into the interior of the structure, and receiving reflected radio signals. The system also includes a processor configured to process the reflected radio signals, so as to obtain a focused image of the reinforcement in at least one selected region within the concrete structure. The image corresponds to the physical condition of the reinforcement. A method for determining the condition of a reinforced concrete structure is also described, utilizing the inspection system.
