  • Patent number: 9805572
    Abstract: An ion chamber provides a current representative of its characteristics as affected by external conditions, e.g., clean air or smoke. A direct current (DC) voltage is applied to the ion chamber at a first polarity and the resulting current through the ion chamber and parasitic leakage current is measured at the first polarity, then the DC voltage is applied to the ion chamber at a second polarity opposite the first polarity, and the resulting current through the ion chamber and parasitic leakage current is measured at the second polarity. Since substantially no current flows through the ion chamber at the second polarity, the common mode parasitic leakage current contribution may be removed from the total current measurement by subtracting the current measured at the second polarity from the current measured at the first polarity, resulting in just the current through the ion chamber.

  • Publication number: 20130122471
    Abstract: Laser target practice using an ultra-violet light emitting laser that is pulsed on when a weapon trigger is pulled. The LTV laser light pulse illuminates a spot on a target having a phosphorus coating on a face thereof. The phosphorus within the illuminated spot glows for a certain time thereby visually indicating a location of the spot on the target. The UV laser light pulse may also illuminate a spot on a target having a photochromic paint coatings on a face thereof. The photochromic paint coatings within the illuminated spot changes color thereby indicating a location of the spot on the target.

  • Publication number: 20120020808
    Abstract: Forces on and respective positions of a pump jack sucker rod are determined in real time by load cells attached to the sucker rod and a position sensor, and are stored for further processing. A wireless transmitter transmits stored load and position values, calculated process parameters, and/or exception alerts to a wireless spread spectrum receiver that can be coupled to a motor speed controller used to set the rotational speed of the pump jack motor, and/or to monitoring systems, such as a central controller used to optimize total field production.

  • Patent number: 6571617
    Abstract: A wireless tire inflation pressure measurement device is used to obtain inflation pressure information for a tire of a vehicle and a signal therefrom may be used for determining the location of the tire. An identifier may be associated with the inflation pressure information for each wheel of the vehicle. Tire rotation speed may be determined by amplitude fluctuations of a radio frequency carrier from a radio frequency transmitter rotating with the wheel. Differences in wheel rotation speeds during a turn may be used in determining the location of each tire of the vehicle. An antenna may be placed on each wheel toward the outer perimeter of the wheel and connected to the radio frequency transmitter. A radio frequency identification (RFID) tag and pressure sensor may be used as the wireless tire inflation pressure measurement device and a RFID pickup coil may be provided in each wheel well for pickup of the inflation pressure signals from each RFID tag on a wheel.

  • Publication number: 20020150140
    Abstract: Measurement of environment parameters beyond a barrier without having to make a hole in the barrier to connect a sensor to the other circuitry may be made using a primary inductor on one side of the barrier inductively coupled to a secondary inductor on the other side of the barrier. A thermistor or other sensor is connected to the secondary inductor and disposed with the secondary inductor on the other side of the barrier. A pulse generator causes a first current through the primary inductor that is modified by a mutually induced second current through the secondary inductor, that is further determined by the resistance or impedance of the thermistor or sensor. A measuring circuit converts the peak current value into a value representative of the temperature or other environment parameter surrounding the sensor.

  • Patent number: 6384762
    Abstract: A digitally switched impedance has improved linearity by minimizing the amount of impedance error introduced by switches used to switch the impedance elements comprising the digitally switched impedance. Improved settling time of the digitally switched impedance is achieved by reducing the amount of switch capacitance connected to the output of the digitally switched impedance. The digitally switched impedance may be fabricated on an integrated circuit die and the switches may be fabricated with complementary metal oxide semiconductor (CMOS) transistors. The number of impedances needed for a desired number of impedance step changes is reduced by using two major impedance ranks and one minor impedance rank, or two minor impedance ranks and one major impedance rank connected in series.
