20110182406 | High resolution imaging system for digital dentistry - The invention provides methods and apparatus for detecting radiation including x-ray photon (including gamma ray photon) and particle radiation for dental x-ray imaging, radiation monitoring, and related industrial and scientific applications. Flat or shaped small (and small hybrid) area storage phosphor plates, available in multiple sizes, are encased in SP-carriers and used as detectors for intraoral dental x-ray imaging as a replacement for analog x-ray film and digital x-ray cameras, offering good detection efficiency, high spatial and contrast resolution, and a wide dynamic range. After removal of the SP-carrier, a small area storage phosphor plate is loaded into a dental storage phosphor scanner for readout. Intermediate and large area storage phosphor plates (including hybrid versions) are suitable for non-intraoral dental x-ray imaging. Suitable storage phosphors may be used in radiation monitoring, replacing current detectors employed in a film badge format. Simple external readers or electronic SP-carriers can provide data readout and thus enable dosimetry. | 07-28-2011 |

20150077258 | Infection control monitoring system - 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. Additional applications include reducing food contamination in food industry, the spread of diseases in schools, in businesses, in corporations and governmental facilities and public access facilities such as public restrooms, dining areas and transportation. | 03-19-2015 |
