  • Patent number: 10889275
    Abstract: Detectable indicia are provided on the interior circumferential rim of the brake hub-drum adjacent to, and spaced apart from, the backing plate of the brake. A sensor is mounted on the backing plate to detect wheel speed and/or other operating conditions detectable from the motion and/or relative location or condition of those indicia. The number of indicia used and the indicia spacing along the interior circumferential rim is selected as needed for a given type of sensor and/or a given application. In the case of a speed sensor, the indicia can be a series of notches in the rim along the entire interior circumferential rim, resembling a series of “teeth” into that rim. The width of those teeth can be formed wide enough to accommodate movement of the hub-drum relative to the backing plate and/or the sensor, without loss of system functionality, according to the sensing tolerances of a given sensor being used in a given application.

Fuel is consumed to provide power (e.g., through power take off) to operate the body components. The vehicle includes sensor device(s) configured to sense the operations of the body components and generate sensor data that describes the operations of the body components. The sensor data is analyzed to determine an amount of fuel that is consumed to power the operations of the body components.

  • Patent number: 10851725
    Abstract: A fuel content detection system is disclosed. The fuel content detection system may include an engine control module (ECM) to receive a measurement of a parameter. The parameter may correlate with an amount of a substance in a fuel that is being consumed in an engine. The ECM may determine an estimation of the parameter based on a model. The model may use a predetermined value associated with the amount of the substance, and the engine may be configured to consume a designated type of fuel that includes an amount of the substance that corresponds to the predetermined value. The ECM may determine, based on the estimation and the measurement not being within a threshold range, that the fuel is not the designated type of fuel and perform an action associated with the engine.

  • Patent number: 10845269
    Abstract: Exhaust gas discharged from an exhaust port is taken into an exhaust gas sampling unit together with the surrounding outside air. A leak detection mechanism, which detects the leakage of exhaust gas from a sampling port, includes a temperature sensor including an outside and an inside temperature sensors, and a temperature measuring instrument for measuring a temperature difference between inside and outside temperatures detected by the temperature sensor. A plurality of inside/outside paired temperature sensors is disposed in the circumferential direction of the sampling port. When a leak occurs, the temperature of the inside temperature sensors rises and the temperature difference between the inside and the outer and outside temperature sensors increases, and the temperature measuring instrument detects the leak. When a leak occurs in a portion of the circumferential direction, only the temperature difference of the portion where the leak occurs is increased, and the location of the leak is identified.
