  • Patent number: 10302542
    Abstract: In a particulate detection system (10), a control board (911), a high voltage generation board (913) and an isolation transformer (720) are respectively disposed in a first space (921d) and a second space (921e) separated from each other by an inner case (923). When electromagnetic noise is generated in the high voltage generation board (913) and the isolation transformer (720); specifically, at the primary winding of the isolation transformer 720, at the time of switching the primary current supply, the electromagnetic noise is blocked by the inner case (923). This configuration reduces the influence of electromagnetic noise generated in the primary winding on the control board (911).

  • Patent number: 10281384
    Abstract: Methods and systems are provided sensing particulate matter by a particulate matter sensor positioned downstream of a diesel particulate filter in an exhaust system. In one example, a method may include increasing an inlet opening of the particulate matter sensor when an exhaust flow rate falls below a threshold to allow more particulates to enter the particulate matter sensor and further includes decreasing the inlet opening when the exhaust flow rate rises above the threshold to reduce the particulates entering the sensor. By adjusting the amount of particulates entering the sensor based on the exhaust rate, and further including a plurality of flow redirectors inside the sensor, the rate of deposition of the sensor and hence the sensitivity of the sensor to the exhaust flow rate may be maintained at a desired level, and independent of the exhaust flow rate.

  • Patent number: 10203309
    Abstract: Chromatographs of a measurement target sample measured in FID and MS are displayed on display unit in a time range defined with reference to the retention index of the target component computed based on the standard retention time and calibration retention time for the target component in FID. The retention index is not readily influenced by difference in column length, thus making it possible to display the peaks of the target component measured with FID and MS in a corresponding time range by displaying the chromatograms on display unit in a time range defined with reference that retention index. Therefore, even in cases where the retention times of the target component in FID and MS are different, measurement results for an identical target component from FID and MS can be easily compared.

  • Patent number: 10202973
    Abstract: A movable counterweight that can reduce lifting and lowering torque. In one embodiment, a beam pumping unit can have a movable beam counterweight attached to a positioning drive on the beam and can be intelligently positioned to achieve lowest net torque required by one or more of a prime mover and lowest net gear torque in in the speed reducer. Optionally, positioning can be calculated by one or more of monitoring current requirements of the motor and monitoring the beam load with a load cell, which can then be merged with crank position readings and processed into signals sent to the positioning drive, which causes the counterweight to move to the best position along the on the length of the beam to achieve one or more of near to lowest current draw by the prime mover and lowest net gear torque in in the speed reducer.

  • Patent number: 10156553
    Abstract: An electronic device may have input-output devices such as sensors. The sensors may include environmental sensors that make measurements on the environment surrounding the electronic device. The environmental sensors may make measurements such as temperature measurements, humidity measurements, gas composition measurements, and particulate level measurements. A sensor may communicate with external air through a sensor port in an electronic device housing. An electronic device may have a movable member. The movable member may be moved in response to motion of the electronic device when handled by user or motion of a button or other movable member that is actuated by the user. As the movable member moves, the movable member may create enhanced airflow through the sensor port. This may refresh the air adjacent to an environmental sensor and enhance sensor response time.
