  • Patent number: 10234336
    Abstract: A temperature identification system may include temperature sensing circuitry and a temperature measurement module. The temperature sensing circuitry may include a ring oscillator that generates a ring oscillator output signal having a frequency that varies depending on an operating temperature on the ring oscillator. A frequency divider circuit may divide the frequency of the ring oscillator output signal such that two or more cycles of a noise component of supply voltage are averaged, which may reduce the impact that the noise has on the frequency of the ring oscillator output signal. In some embodiments, a regulator may supply a regulated voltage to the ring oscillator. The regulator may reduce the impact of the noise for low frequency components of the noise, while the frequency divider may reduce the impact for high frequency of the noise.

  • Patent number: 10215643
    Abstract: There are many industrial applications in which non-contact temperature sensing is useful for increasing production speed and quality, such as printing, laminating, extrusion, and metal forming. Disclosed is a non-contact temperature determining apparatus which uses two wide wavelength bands integrating sensors to determine the radiance ratio of a target and thereby determine a corresponding temperature of the target. Also disclosed is a non-contact temperature determining apparatus in which a beam splitter passes one wide wavelength band to a sensor and reflects another distinct wide wavelength band to another sensor from which temperature can be determined. A disclosed embodiment of the dual waveband temperature detector improves upon traditional and currently available ratio pyrometers by further reducing the cost of the system, making installation and use easier, and improving temperature detection for low temperature industrial applications.
