  • Patent number: 9862344
    Abstract: A load exerted on one of supporting parts supporting a seat of a vehicle is detected and is corrected according to an inclination of the vehicle. A load object on the seat is determined a plurality of times of turning on and turning off an ignition of the vehicle using the load thus corrected or the load detected. The load object is determined as an adult at least when the load is greater than or equal to a first threshold and determined as other than an adult at least when the load is less than a second threshold that is less than the first threshold. A function is further provided of determining the load object from a combination of a magnitude relation between the load and a third threshold less than or equal to the first threshold and greater than the second threshold and the inclination of the vehicle.

  • Patent number: 9857322
    Abstract: A semiconductor gas sensor includes a CMOS inverter which is configured by an n-channel field effect transistor having a catalytic gate and a p-channel field effect transistor having the catalytic gate. An input setting gate potential Vin(D) of the CMOS inverter is set to satisfy “Vin(D)=Vtc??Vgth” by using the sensor response threshold intensity ?Vgth determined by a concentration of a gas to be detected and a threshold input potential Vtc of the CMOS inverter. Therefore, only by setting the input setting gate potential Vin(D), a warning or an alarm can be issued for the concentration of the gas to be detected. In addition, a temperature compensation of the threshold voltage caused by a MOS structure is reduced regardless of the detection gas by setting a characteristic coefficient ?R, a threshold voltage Vtn of the n-channel field effect transistor, and the threshold voltage Vtp of the p-channel field effect transistor so as to satisfy relations “?R=1” and “Vtp=?Vtn”.

  • Patent number: 9857243
    Abstract: An array of resonant sensors self-corrects measured values for the effects of environmental conditions, such as operating temperature, pressure or humidity. The resonant sensors have varied frequency responses to N environmental parameters and M chemical parameters. Each of the sensors has a different, non-zero frequency response to at least two of the parameters. The device also comprises at least one detector for detecting frequency responses of the resonant sensors. Individual parameter values are determined for each of the N environmental parameters and M chemical parameters according to the detected frequency responses and a system of equations using calibration terms that relate the frequency responses to the individual parameter values.

  • Patent number: 9822737
    Abstract: A method for a fuel system, comprising: indicating a leak in a fuel tank following applying a vacuum to the fuel tank by running a vacuum pump in a first direction; then purging a fuel vapor canister to the fuel tank by running the vacuum pump in a second direction, opposite the first direction. In this way, the fuel vapor canister may be purged of its contents following a fuel system leak check. This may reduce bleed emissions while increasing the efficiency of the vehicle, as the engine does not need to be turned on in order to purge the canister.

  • Patent number: 9817023
    Abstract: A sensor with continuous self test is provided. An exemplary inertial sensor may include one or more self test electrodes so that one or more test signals may be applied to the electrodes during normal operation of the sensor. Normal sensor output may be read and stored during normal operation, when self test signals are typically not applied to the sensor. The normal sensor output provides a baseline for comparison to a sensor offset error detection signal produced when a test signal may be applied to one self test electrode, and also to a sense error detection signal when a test signal may be applied to both self test electrodes.

  • Patent number: 9810677
    Abstract: A concentration detecting section detects a concentration of urea water and outputs the detected value. A determining section determines whether the urea water is suitable by using the detected value. A temperature detecting section detects temperatures of detection targets. The detection targets have temperatures that are different from one another during operation of an engine. The determining section is adapted to calculate a temperature difference between temperatures of a particular detection target and another detection target and start determining whether the urea water is suitable when a determination start condition including that the temperature difference is within a reference range is satisfied. The reference range is defined as a range of temperature differences in which it is determined that the urea water is in a quiescent state, which is suitable for the determination.

  • Patent number: 9810567
    Abstract: A sensor assembly is described herein that can automatically calibrate itself upon installation into an empty bin, eliminating the need to actually fill the bin to calibrate the level reading. The sensor will provide consistent measurement regardless of material properties (permittivity, density, temperature or moisture content). The capacitive nature of the sensor means that in some circumstances, it will sense the material through plastic/glass/fiber glass thereby allowing the sensor assembly to be mountable on the outside of a bin or container. The electrodes of the sensor system are designed to provide a continuous level reading.
