Abstract: A sensor is mounted to or embedded in a wheel hub. The sensor node includes a power source and a sensing device that detects and monitors at least one parameter associated with the wheel hub. The sensor node also includes a communication module that communicates via wireless communication signals and a processing device in communication with the sensing device and the communication module. The processing device collects data from the sensing devices, processes the data, and based on that processing, communicates information relating to the wheel hub to a remote server or network. A mesh network of multiple sensor nodes can be applied to multiple different wheel hubs on a vehicle and communicate with a central processing device. The processing device can thus monitor performance and/or operation of each wheel hub.

Abstract: A fluid level sensing system includes a mounting strip and fluid sensing nodes coupled to the mounting strip. Each fluid sensing node is switchable between a fluid present state and a fluid absent state. Each fluid sensing node includes a prism, a photoemitter and a photoreceptor. The photoemitter and photoreceptor are interposed between the prism and the mounting strip. In the absence of fluid around the prism, the photoreceptor receives greater than a threshold amount of light from the photoemitter internally reflected by the prism to switch the fluid sensing node to the fluid absent state. When the prism is covered in fluid, the photoreceptor receives less than the threshold amount of light from the photoemitter to switch the fluid sensing node to the fluid present state. A processor determines a fluid level based on the fluid detection states of the fluid sensing nodes.

Abstract: The present disclosure provides a device for monitoring oil pressure in an oil cylinder of a diaphragm compressor, including a piston rod and a strain gauge circuit. The strain gauge circuit includes a strain gauge component and a bridge circuit connected, and the strain gauge component is arranged on the surface of the piston rod. A strain gauge component is noninvasively arranged on the piston rod of the diaphragm compressor to measure the load of the piston rod, such that the oil pressure can be measured indirectly, and thus the oil pressure of the diaphragm compressor can be measured nondestructively. Nondestructive and noninvasive monitoring of the diaphragm compressor is safe and reliable, and can achieve accurate monitoring of the oil pressure especially in high-pressure working conditions.

The exhaust gas sensor includes a ceramic sensor element having at least one measuring electrode and a heating device. A binary dewpoint end signal is calculated, based on data which relate to the internal combustion engine and the exhaust gas sensor, which indicates whether or not the occurrence of liquid water in the exhaust system is still to be expected. Whenever the vehicle is turned off and the dewpoint end signal simultaneously has the value which signals that the occurrence of liquid water in the exhaust system is still to be expected, the sensor element is heated by its heating device to a temperature for a certain period of time in such a way that the sensor element dries.

Abstract: The exemplary embodiments may determine a temperature set point for an outlet heater or cooler based on available information without requiring user input or requiring only minimal user input. The exemplary embodiments may estimate the temperature set point of the outlet heater based on available information, such as pressure delta along the column, temperature at the inlet of the chromatography column, and volumetric flow rate. In some instances, the estimate may be normalized for column dimensions, such as length and diameter. Tailing factor may also be used in determining the estimate. The estimate is not computationally burdensome and can be recalculated as the chromatography column is in use.

Abstract: A system includes an alarm, a tilt detector, and a power supply communicatively connected to the tilt detector and communicatively connected to the alarm. The tilt detector, when no tilt is detected, prohibits communicative connection of the power supply to the alarm and, when tilt is detected, effects communicative connection of the power supply to the alarm. The system does not consume power of the power supply unless and until the system tilts causing the tilt switch to communicatively connect the power supply to the alarm. The alarm sounds on tilt until such time as the system is reset.
