  • Patent number: 11112391
    Abstract: A degree of similarity in the peak pattern between a mass spectrum obtained for an unknown target substance in a sample and a mass spectrum of a known specific substance is calculated (S4). If the degree of similarity is within a range of 80-60% (“No” in S6), the ratio between the signal intensities at two mass-to-charge ratios characteristic of the specific substance is calculated and compared with a reference value (S7 and S8). If the intensity ratio exceeds the reference value, the target substance is likely to be the specific substance. Therefore, as in the case where the degree of similarity is equal to or higher than 80%, it is concluded that the specific substance is contained in the sample (S10).

  • Patent number: 11096648
    Abstract: For dose calibration (39) in functional imaging, different precision sources (22, 25) for a same long-lived isotope are used to calibrate, avoiding having to ship one source from one location to another location. A ratio of sensitivities of a gas ion chamber-based dose calibrator (20) at a reference laboratory to the precision source (22) of the long-lived isotope to a source (23) with an isotope to be used for imaging is found. At the clinical site (e.g., radio-pharmacy or functional imaging facility), a measure (34) of the sensitivity of a local gas ion chamber-based dose calibrator (24) to the other source (25) with the long-lived isotope and the ratio from the remote gas ion chamber-based dose calibrator (20) are used to determine sensitivity of the local gas ion chamber-based dose calibrator (24) to the isotope of the radiopharmaceutical (26).

  • Patent number: 11092693
    Abstract: A system and method provide automatic RF path gain calibration independent of RF interference levels to preserve solution trust capabilities. After a system is powered ON, or a new antenna is attached (hot swap), a smart antenna assembly combined with a jammer power estimator within an RF receiver functions to autonomously measure internal gains within the RF path, calibrate the new antenna installation, and thereby measure a level of interference associated with the external environment from that point forward. A controller commands the antenna calibration retrieving antenna details and RF path gain calibration while measuring local jamming at the receiver input. Should the controller determine a level of jamming effectiveness is present, it offers a user a display of the local jamming levels enabling the user accurate theater decision making regarding the accuracy and availability of desirable signal.

  • Patent number: 10981406
    Abstract: A security feature for protecting valuable documents, in particular for ensuring the authenticity of valuable documents, comprises a luminescent pigment which has a host lattice doped with a first luminophore and a second luminophore, with an excitation energy of the first luminophore being transferable to the second luminophore. However, in the case of the luminescent pigment according to the invention, the excitation energy is not transferred completely from the first luminophore to the second, but rather only partially. The incomplete transfer of the excitation energy is achieved by selecting suitable amount-of-substance fractions of the first and the second luminophores on the luminescent pigment. As a result of the incomplete transfer of the excitation energy, the luminescent light that is emitted by the luminescent pigment also has, in addition to a luminescence peak of the second luminophore, a luminescence peak of the first luminophore.

A system-specific planar sensitivity is computed for a combination of the collimator and detector using the number of gamma photons acquired, a time duration of the acquisition, and precalibrated radioactivity data of the point source corrected for decay that occurred after a precalibration time. A deviation of the computed system-specific planar sensitivity from a class standard sensitivity value for a combination of the radioactive point source, the collimator, and the detector is computed. A class standard sensitivity value for a combination of a radiopharmaceutical, the collimator, and the detector is scaled by the computed deviation, yielding a scaled system-specific sensitivity value for the radiopharmaceutical.

  • Patent number: 10692178
    Abstract: In an optical system, a color filter mosaic can determine first color pixel locations, second color pixel locations, and third color pixel locations in an array of sensor pixels. The optical system can capture overhead images, which can be subtracted to form a background-subtracted tri-color image of a reflection of sunlight from at least one ground-based curved mirror. A processor can scale color values at the first and second color pixel locations of the tri-color background-subtracted image. The processor can form a single-color background-subtracted image from the scaled color values at the first color pixel locations, the scaled color values at the second color pixel locations, and third color values at the third color pixel locations. The single-color background-subtracted image can correspond to a point spread function or a line spread function of the optical system.

  • Patent number: 10692693
    Abstract: A pattern measuring device ensures highly accurately measuring a depth and a three-dimensional shape irrespective of a formation accuracy of a deep trench and/or a deep hole. Therefore, in the present invention, the measuring system detects backscattered electrons from a pattern caused by an irradiation, compares backscattered electron signal intensities from a top surface, a bottom surface, and a sidewall of the pattern, and calculates a three-dimensional shape (or height information) of the sidewall based on a difference in heights of the top surface and the lower surface. The measuring system compares the calculated three-dimensional shape of the sidewall with a three-dimensional shape of the sidewall estimated based on an intensity distribution (open angle) of a primary electron beam, corrects the estimated three-dimensional shape of the sidewall based on a difference in the comparison, and corrects until the difference in the comparison becomes an acceptable value.
