  • Patent number: 11512985
    Abstract: A timing apparatus, system, and method are provided to determine a position of a rotating object in a device, such as an engine, and control the device according to the determined position of the rotating object. Light is emitted from a light source onto a reflecting region on a portion of the rotating object. Light is reflected off the reflecting region of the rotating object and detected as the rotating object rotates. Intensity of the reflected light is measured, via a microcontroller, and the position of the rotating object is determined according to the intensity of the detected light. A signal is generated that corresponds to the intensity of the detected light associated with the determined position of the rotating shaft. The reflecting region has a feature configured to effect a change in the intensity of the reflected light as the rotating object rotates.

  • Publication number: 20210324968
    Abstract: A valve actuator system includes a valve actuator assembly having a body defining an interior cavity and a piston coupled to a piston rod and movable within a piston cylinder provided within the interior cavity. The piston cylinder has a first chamber on a first side of the piston and a second chamber on a second rod side of the piston. One or more electronic components are disposed within the interior cavity and include at least one processor. The one or more electronic components are configured to move the piston via controlled air pressure and to continuously monitor and/or determine a position of the piston rod relative to the piston cylinder. A fail-safe reservoir is coupled to a source of air and is connected to both the first chamber and the second chamber to provide operating air thereto.

  • Patent number: 10132655
    Abstract: An apparatus, a system and a method for detecting position of a movable object in a device and using the same for controlling the device. A distance and/or an intensity of emitted light may be measured by using a sensor to emit light and detect light to determine the location of the movable object. The movable element absorbs emitted light from the sensor. The sensor determines and/or measures an intensity of the emitted light from the sensor which is not absorbed by the movable object. The intensity of emitted light is related to the position of the movable object in the device. A microprocessor may determine the position of the movable object based on the intensity of emitted light detected by the sensor. The position of a rotating object on a crankshaft in an engine may be detected.

  • Patent number: 9182342
    Abstract: An apparatus, a system and a method use a light-emitting diode (LED) to identify the presence of a material in a gas and/or a fluid and/or to determine properties of the material. The LED and a light detector may be used to determine a chemical compound in the material. The gas and/or the fluid may be located in a chamber. A first light detector may be positioned on the opposite side of the chamber relative to the LED, a second light detector may be positioned on the same side of the chamber as the LED, and/or a third light detector may be positioned inside the chamber. Additional light detectors with coatings may enable measurements to be corrected for the effects of temperature. The light detectors may determine light reflection, light refraction, light transmission, light diffraction, light interference, light diffusion, light collimation, light absorption and/or light focusing of the material.

The real time information may be encrypted and may be transmitted to a central location using Wi-Fi communication, a cellular telephone network, radio transmission, a transponder, and/or the like. The real time information may be accessed by a terminal communicatively linked to the microprocessor and/or the central location. The signal may indicate vehicle compliance and/or non-compliance with a private commercial requirement and/or state and federal regulations.

  • Patent number: 8436287
    Abstract: A system and/or a method read, measure and/or control intensity of light emitted from a light-emitting diode (LED). A light detector may be located in a position adjacent to the LED for reading and/or measuring the intensity of light emitted from the LED. The LED and the light detector may be located in a cavity which may limit exposure of the LED and the light detector to ambient light. The cavity may have an aperture for allowing light emitted from the LED to exit the chamber to illuminate an environment in which the chamber is located. The aperture may be located between the cavity and a compartment, and the LED may emit light through the aperture into the compartment. An additional detector may be located in the compartment and/or may extend from the cavity through an additional aperture into the compartment.
