Abstract: A liquid level, composition and contamination sensor generates an RF signal across a resonant circuit that includes a variable inductor and capacitor. The resulting electromagnetic radiation is propagated into the liquid and changes in impedance and resonance of the resonant circuit that result from changes in the conductivity and dielectric properties of the liquid, which are proportional to liquid content and volume, are detected. The conductivity and dielectric properties of the liquid are measured, based on the changed impedance and resonance of the resonant circuit, and are compared to determine aging and contamination of the urea solution by other liquids. Also, an optical sensor may be submerged in the liquid to determine the refractive index of the liquid. The refractive index of the liquid may be used to determine: if the liquid is water or a urea solution; the concentration of a urea solution.

Abstract: A belt monitoring system employs a belt having at least one reinforcement member made from a conductive reinforcement material. A belt monitor is disposed in conjunction with the belt. The belt monitor comprises a field inductor excited by an applied signal. An electrical characteristic of at least a portion of the field inductor as influenced by changes in the electrical properties of the conductive reinforcement member is monitored in order to determine a physical condition of the conductive reinforcement member and thereby monitor a physical characteristic of the belt. This monitoring may be carried out by a sense inductor disposed adjacent or in conjunction with the field inductor.

Abstract: A tire monitor system ( 100) employs a single RF detector ( 112) mounted on the vehicle. The tire monitor system (100) also includes a control unit ( 110) and a receiver ( 120). The single RF detector ( 112) is positioned to be proximate a front axle or a rear axle. The RF detector (112) also may be positioned off-center. The control unit (110) distinguishes front tire monitors from rear tire monitors by comparing a number of RF transmissions received by each tire monitor. The control unit also may distinguish between left tire monitors and right tire monitors by comparing the number of RF transmissions received by each tire monitor. In other embodiment, the tire monitor system (100) may further use a received signal strength and/or acceleration signals to determine position information of the tire monitors.

Abstract: An automotive urea solution monitoring device (100) is deployed in conjunction with the urea tank (102) of a selective catalytic reduction vehicle. An RF signal of a constant frequency is generated across a resonant circuit (410), which is comprised of an inductor (411) and a PCB trace capacitor (412). Electromagnetic radiation is propagated into the automotive urea solution in the urea tank. The conductivity and dielectric properties of the liquid change the impedance of the discrete/trace capacitor (412) and or the discrete/trace inductor (411). These changes are proportional to ammonia content, temperature, and/or level of the automotive urea solution in the urea tank and are detected by a microcontroller (401), and then transmitted to a selective catalytic reduction vehicle engine management system.

Abstract: A remote tire monitor system (102) includes a control unit (112) and a plurality of tire monitors (124, 126, 128, 130) mountable on respective wheels (104, 106, 108, 110) of a vehicle (100) to transmit radio signals to the control unit. The tire monitors each include a pair of motion sensors such as shock sensors (210, 212) and a control circuit (202) configured to determine position information for the respective tire monitor based on first and second shock sensor signals from the pair of shock sensors. The shock sensors produce an output voltage proportional to a change in applied force. Therefore, the offset created by centrifugal force in previously used accelerometers is absent, simplifying design of the tire monitors.

Abstract: A flex fuel sensor is deployed in conjunction with the fuel transfer line (e.g. around a plastic fuel line) or at the bottom/side of a fuel tank. An RF signal of a constant frequency may be generated across a resonant circuit, which comprises of an inductor and a PCB trace capacitor, capacitor plates, semi cylindrical capacitor plates, or the like. Electromagnetic radiation is propagated into the passing fuel in the transfer pipe. The conductivity and dielectric properties of the fuel change the capacitance of the trace capacitor/capacitor plates. These changes are proportional to ethanol/alcohol content of the fuel and are preferably detected by a microcontroller, or the like, and then transmitted to a flex fuel vehicle Engine Management System.
