A system for monitoring a foundation includes a sensor cartridge assembly. The sensor cartridge assembly includes a sensor disposed in a sensor tube and a sensor head attached to an end of the sensor tube. Wiring coupled to the sensor and routed in the sensor tube to the sensor head conveys power and/or telemetry between the sensor and a controller. The sensor tube is configured to be inserted into a raceway attached to a foundation. The raceway may be within the foundation and/or located at a perimeter of the foundation. A method for monitoring a foundation includes deriving an elevation of the foundation at the location of the sensor based on pressure measurements made by the sensor within the sensor tube.

A pressure calibration apparatus and a pressure instrument calibration information processing method, belonging to the field of pressure instrument measurement and calibration. The pressure calibration apparatus comprises: a pressure calibration unit (1) externally connected to the calibrated pressure instrument (100); a main control unit (2), which is electrically connected to the pressure calibration unit (1); a communication module (3) that is electrically connected to the main control unit (2), and carries out data interaction with a remote database (300) through a network (200). The pressure calibration apparatus can be in a real-time communication connection with the remote database (300), and implements on-field real-time downloading of historical calibration data and calibration schemes of the calibrated pressure instrument (100) and real-time uploading of current calibration data.

An air filter includes filter media, a sensor, and circuitry coupled to the sensor, the circuitry configured to receive data from the sensor representative of the condition of the filter media and wirelessly transmit such data. The data may be received by a device with a display to use the information to present an indication of the filter media condition to a user.

A device, such as a link box, with health monitoring has a housing defining an interior space, at least one surge arrester positioned in the interior space, at least one contactless temperature sensor positioned to contactlessly measure a temperature of the at least one surge arrester and generate temperature data therefrom, and at least one controller connected to the at least one contactless temperature sensor and configured to receive the temperature data.

A tire air pressure detection device includes a plurality of transceivers and a receiver. The plurality of transceivers are correspondingly provided in a plurality of wheels of a vehicle. Each wheel has a tire. The receiver is attached to a vehicle body. Each of the plurality of transceivers outputs a detection signal indicative of an air pressure of the tire of the corresponding wheel. Each of the plurality of transceivers processes the detection signal, and generates a frame storing the processed detection signal as data related to the air pressure of the tire. The receiver receives the frame. The receiver detects the air pressure of the tire based on the data stored in the received frame.

A sensor system (10) has a medical device provided with a first transmission/reception unit (16) installed inside a medical instrument (12) to output a detection signal of a sensor unit (22), and a second transmission/reception unit (18) detachably installed outside the medical instrument (12) to transmit/receive a signal to and from the first transmission/reception unit (16) in a contactless manner. The first transmission/reception unit (16) and the second transmission/reception unit (18) are arranged so as to be opposed to each other across the medical instrument (12) to transmit/receive the signal by electromagnetic induction.

A liquid monitoring system includes a remote measurement device located at a location of the fire hydrant that is in contact with water provided by a water main. The remote measurement device has sensors that measure characteristics of the water and a communication interface that transmits measured information to a communication network device that may be located elsewhere on the fire hydrant. The communication network device communicates with a communication network.

A wireless sensor includes a radio frequency (RF) front end, a sensing element, and a processing module. The RF front end sends a coded digital value to a sensing computing device via an RF signal. The sensing element senses an environmental condition of an item. The processing module determines an effect on an operational parameter of an RF front end of the wireless sensor as a result of the sensing element sensing the environmental condition. The processing module also adjusts tuning of the RF front end to mitigate the effect on the operational parameter and equates an amount of adjusting of the tuning of the RF front end to the coded digital value.
