  • Patent number: 10928545
    Abstract: The present disclosure provides a gamma-ray attenuator and a gamma-ray shield for use in gamma-ray spectroscopy. The gamma-ray attenuator is a sleeve comprising a wall, a distal end, and a proximal end. The distal end of the sleeve is closed, and the proximal end of the sleeve forms an opening. A copper insert, a tin insert and a tungsten insert are installed in the sleeve such that the copper insert is adjacent to the distal end and the tungsten insert is closest to the proximal end. The sleeve is comprised of one or more materials that do not substantially attenuate gamma-rays. The open end of the sleeve fits over a tungsten safe that is operable to hold a radionuclide sample. When fitted together, a gamma-ray attenuator and a safe comprise a gamma-ray shield.

    Abstract: A system and method for evaluating integrity of cement in a wellbore with multiple casing strings. The system and method may include at least one source that can emit a field of photons, and at least one photon detector spaced away from the source by a first distance that configures the tool to measure cement integrity in a first annulus, by a portion of the source photons being scattered back to the first detector which can produce photon count rates based on energy levels of received photons. Integrity of cement in the first annulus can be determined by the photon count rates. A second detector spaced a second distance from the source can be included and can measure cement integrity in a second annulus that is radially outside the first annulus by producing photon count rates for photons received from the second annulus.

  • Patent number: 10921481
    Abstract: A system and method for making measurements inside a wellbore makes use of a diamond crystal with a nitrogen vacancy center (NV-center) to sense temperature, pressure, magnetic fields, strain, electric fields, or other parameters of the downhole environment. The system includes a microwave source that can be positioned to produce microwaves inside the wellbore and a light source that can be positioned to produce interrogation light inside the wellbore. The NV-center of the diamond is struck by the interrogation light. A spectrometer can be adapted to receive the excitation light output from the NV-center and produce a spectrum of the excitation light. The spectrum is indicative of the value of the parameter inside the wellbore.

  • Patent number: 10900898
    Abstract: A security feature has a plurality of luminescent surface elements, wherein luminescence lifetime varies between the surface elements. In order to verify the security feature, a lock-in imager is used. The security feature is illuminated with excitation light, which is intensity-modulated with a modulation frequency. The luminescent light emitted by the security feature is detected synchronously with the modulation frequency in a plurality of pixels. This is used to determine a measure of a phase shift between the excitation light and the luminescent light in different pixels. The security feature is verified taking account of the measure of the phase shift in different pixels.

  • Patent number: 10866143
    Abstract: An infrared photodetection system is provided that is capable of measuring infrared light up to high-temperature regions while improving a temperature resolution for low-temperature regions without increasing image-acquisition time even if the measuring temperature range varies. The infrared photodetection system is set up to exhibit sensitivity spectrum SSP1 for high sensitivity (for low temperature use) and sensitivity spectrum SSP2 for low sensitivity (for high temperature use) in the transmission band of the bandpass filter when different voltages are applied to a quantum-dot infrared photodetector. The infrared photodetection system then integrates temperature data for the infrared light detected using sensitivity spectrum SSP1 and temperature data for the infrared light detected using sensitivity spectrum SSP2, in order to output a temperature distribution in a measurement region.
