Patent number: 10914847Abstract: A structured dental x-ray detector implements an array of holes or channels filled with at least one of polycrystalline, amorphous, or nano-particle semiconductor x-ray or gamma ray converter materials. Readout electronics are configured for acquiring and analyzing signals from the detector; e.g., operating in a signal integration or photon detecting mode, or in a photon detecting mode with energy resolution. In dental application, a protective shell or frame can be provided to encapsulate the detector and readout electronics, with a wired or wireless communications link to a computer system configured for image data post-processing and storage of the readout signals, with an electronic display for the image data.Type: GrantFiled: September 6, 2011Date of Patent: February 9, 2021Assignee: Minnesota Imaging and Engineering LLCInventors: Robert Sigurd Nelson, William Bert Nelson

Patent number: 10482753Abstract: The invention provides an automated hand hygiene/infection control monitoring sensor-based system suitable for improving hand hygiene and multiple infection control measures and ensuring compliance by health care workers as well as visitors to hospitals and clinics. The use of biometric identification devices such as cameras for face recognition and profiling, microphones for voice recognition, etc. permit highly accurate identification without the use of removable identification devices such as identification badges which may include bar codes, magnetic strips or wireless devices such as RFIDS. Identification badges are removable and hence susceptible to being lost, misplaced, etc. Visitors are typically not assigned identification badges and hence enforcement of hand hygiene policies is minimal.Type: GrantFiled: September 17, 2013Date of Patent: November 19, 2019Assignee: Minnesota Imaging and Engineering LLCInventors: William Bert Nelson, Robert Sigurd Nelson, Glenn Albert Nickele
