  • Patent number: 10914047
    Abstract: A system for detecting an intrusion of at least one of a monitoring fiber and a detector comprises a sensor having a closure monitor and an intrusion monitor, the closure monitor including a signal generator and at least one detector attached to the monitoring fiber. The signal generator transmits signal light such that the monitoring fiber receives the transmitted signal light and reflects a portion of the signal light via the at least one detector to the closure monitor and transmits a non-reflected portion of the signal light. The intrusion monitor receives the transmitted non-reflected portion of the signal light, and monitors the non-reflected portion of the signal light to detect transient changes in the non-reflected portion of the signal light indicative of at least one of a vibration, a motion and a handling of at least one of the monitoring fiber and the at least one detector.

  • Patent number: 10809413
    Abstract: A sensor assembly for passive detections of downhole well features. Embodiments include a casing collar locator assembly that utilizes fiber optics in combination with a magneto-responsive sensor to detect casing collars and provide real-time location information in a well. The sensor may be configured to work with a poled monolithic structure that is dimensionally responsive to voltage in a way that substantially eliminates noise during detections. Additionally, the sensor may be intentionally imbalanced, utilizing multiple fibers of different lengths and multiple wavelength monitoring so as to provide enhanced directional information as well as allow operators to decipher and address circumstances of polarization fade.

  • Patent number: 10805123
    Abstract: A method of detecting crosstalk for a digital isolator having first and second channels including two die with channels including a transmit side, receive side, with ?1 die including a capacitive barrier for each channel. A first clock signal at a first frequency in a first pulse pattern and a second clock signal at a second frequency in a second pulse pattern are configured, wherein the pulse patterns have a phase difference. The transmit side of the channels each encode their received clock pulse pattern, then modulate with a carrier frequency to provide a fc1 and a fc2 signal, respectively. The receive side of the channels demodulate received signals during a rising or falling edge of their clock signal to generate a delayed received version of the first and second clock pulse pattern. Missing pulses are identified by comparing the delayed received clock pulse patterns to their clock pulse patterns.

  • Patent number: 10794684
    Abstract: A touch probe for sensing the position of a surface, having a housing and a moving assembly supported within the housing and including a flexible reflective element, a spacer element, and a semitransparent element, wherein a reflective surface of the flexible reflective element and a surface of the semitransparent element are separated by the spacer element, and a stylus connected to the flexible reflective element. Movement of the stylus responsive to a force causes the flexible reflective element to flex and change distances between points on the reflective surface and on the surface of the semitransparent element. Coherent light incident upon the semitransparent element and directed towards the reflective surface creates interference fringes dependent upon separation distances between the reflective surface and the surface of the semitransparent element. A detector senses changes in the interference fringes patterns in response to flexing of the flexible element.
