Patent number: 7995205Abstract: Apparatus and methods are disclosed for viewing low-birefringence structures within samples directly, with the eye, in real-time. The sample is placed between an entrance polarizer and analyzer polarizer, the transmission state of one of which is changed dynamically to create a modulated view of the scene; against this background, birefringent structures are visible because of their different appearance when modulated. Modulation rates of 4 or more states per second; use of 4 or more states, or even a continuum of states, which lie substantially on a latitude line on the Poincare sphere; and orientation of the polarization components to produce a uniform background; produce a clear view that does not produce operator fatigue. Broad-band wavelength operation spanning 50 nm or more, or the whole visible range, is achieved, and it is compatible with integration into other microscopy modes such as Hoffman relief contrast.Type: GrantFiled: November 18, 2008Date of Patent: August 9, 2011Assignee: Cambridge Research & Instrumentation, Inc.Inventors: Peter Miller, David Fletcher-Holmes, Cathy M. Boutin, Clifford Hoyt

Patent number: 7917376Abstract: Systems and methods are provided for facilitating management of health care in medical facilities such as hospitals, clinics, emergency rooms, etc., for example by monitoring and assessing the quality of patient care. Data is collected and operated on relating to medical conditions, treatment, cost, care, events, outcomes and results of treatments, and data representing the collective experience of similar patients is mined to discover opportunities to improve the quality of health care. Statistical and comparative data and reports including such and other information indicate a quality of care and provide epidemiologically cogent information. Quality of care may be considered as achieving desired or expected norms of performance, including success, in a timely fashion, and can be judged not just by what functionally happens during a patient instigated encounter, but also by long term outcomes evidenced by the patient's passage through the health care delivery system.Type: GrantFiled: September 12, 2008Date of Patent: March 29, 2011Assignee: Montefiore Medical CenterInventors: Eran Bellin, David Fletcher, Noah Geberer

Publication number: 20050237532Abstract: The present invention relates to an imaging apparatus and comprises input and output polarisers, a first polarising beam splitter and at least one additional polarising beam splitter, a light sensitive detector and focussing means arranged on an axis. The input polariser resolves incident light into a single linear polarisation state. The first polarising beam splitter receives light from the input polarises, and resolves it into equal magnitude orthogonally polarised rays which are mutually spaced and have a path difference therebetween. The or each additional polarising beam splitter is arranged to receive light from the first polarising beam splitter. The transmission axis of the output polariser is parallel to or perpendicular to the transmission axis of the input polarises to resolve the orthogonally polarised light rays having past through the or each additional polarising beam splitter into the same or perpendicular polarisation state as light resolved by the, first polariser.Type: ApplicationFiled: June 19, 2003Publication date: October 27, 2005Inventors: John Edward Perrigo Beale, Andrew Harvey, David Fletcher-Holmes
