Publication number: 20140218680Abstract: The proposed innovation provides methods and systems for measuring the interpupillary distance. The proposed innovation provides a fitting pad (102) having two detection points (104 and 106). The fitting pad is placed on the forehead of the user and an image is captured. The image is uploaded and pupil distance calculator software locates the fitting detection points and calculates the distance in pixels of the left and right X, Y coordinates. The software creates an image scale by dividing the pixel counts between the detection points. The software automatically locates the X, Y coordinates between the center of the left and right pupils and calculates the distance in pixels. The resulting pixel distance divided by the image scale provides the interpupillary distance in millimeter. In embodiments, ssegment height is calculated based upon an image imported by the user and the combined scaled images of the user and the frame.Type: ApplicationFiled: April 7, 2014Publication date: August 7, 2014Inventors: Hal Edward Wilson, James Gerard Welch

Publication number: 20140218720Abstract: An apparatus and method to map the body habitus, without the use of ionizing radiation, and to simultaneously track the position of an ionizing radiation imaging detector with respect to the body habitus map so that the radiotracer distribution of the patient can be fused with the body habitus map and thus provide an anatomical reference for the radiotracer distribution within the patient. A depth camera, capable of imaging a 3-dimensional surface, is attached to an ionizing radiation imaging detector where the relative position between the two is known.Type: ApplicationFiled: February 4, 2014Publication date: August 7, 2014Applicant: Novadaq Technologies Inc.Inventor: Joel KINDEM

Publication number: 20140218721Abstract: A device includes a memory and a processor coupled to the memory operable to perform operations. The operations include determining a first estimated distance associated with a first location of an optical fiber based on first light detected by a sensor, where the first light is detected at a first time when a portion of the optical fiber has a first configuration, and determining a second estimated distance associated with a second location of the optical fiber based on second light detected by the sensor, where the second light is detected at a second time when the portion of the optical fiber has a second configuration. The operations further include determining a third estimated distance associated with a third location of the optical fiber based on the first estimated distance and the second estimated distance, where the third location is associated with a fault in the optical fiber.Type: ApplicationFiled: April 10, 2014Publication date: August 7, 2014Applicant: AT&T INTELLECTUAL PROPERTY I, L.P.Inventor: Bryan Smith

Publication number: 20140218722Abstract: An optical inspector includes a radiating source, a time varying beam reflector, a telecentric scan lens, a first and second lens, a field stop, and a detector. The radiating source irradiates a first position of on the time varying beam reflector with a source beam. The time varying beam reflector directs the source beam to the telecentric scan lens, which in turn directs the source beam to a sample. The first lens focuses scattered radiation from the sample to generate multiple scan lines at a first focal plane. The field stop is positioned at the first focal plane to block one or more scan lines at the first focal plane. The scan line not blocked by the field stop propagates to the second lens. The second lens de-scans the scan line and generates a point of scattered radiation at a second focal plane where the detector input is located.Type: ApplicationFiled: February 1, 2013Publication date: August 7, 2014Applicant: Zeta Instruments, Inc.Inventors: Steven W. Meeks, Rusmin Kudinar, Hung P. Nguyen

Publication number: 20140218724Abstract: An optical inspector includes a radiating source, a time varying beam reflector, a telecentric scan lens, a separating minor, and a first and second detector. The radiating source is configured to irradiate a first position on the time varying beam reflector with a source beam. The time varying beam reflector directs the source beam to the telecentric scan lens, which in turn directs the source beam to a sample. The telecentric scan lens directs specular reflection and near specular scattered radiation to the time varying beam reflector. The specular reflection is directed by the separating mirror to the first detector. The near specular scattered radiation is not reflected by the separating minor and propagates to the second detector. In response, the optical inspector determines the total reflectivity, the surface slope, or the near specular scattered radiation intensity of the sample.Type: ApplicationFiled: February 1, 2013Publication date: August 7, 2014Applicant: ZETA INSTRUMENTS, INC.Inventors: Steven W.
