Patent number: 8335419Abstract: An optical component includes at least one light-guiding element with a side surface extending between incident and emission faces between which light that is introduced into the incident face can propagate by internal reflection. Disposed over at least a portion of the side surface of at least one of the at least one light-guiding elements is an extramural absorption material that is configured to selectively absorb “stray light” that enters the incident face of the light-guiding element, but which exists through the side surface instead of the emission face. The absorption material is fabricated, at least in part, from an electro-chromic material exhibiting a translucency that is selectively adjustable in response to changes in at least one of (i) electrical current applied through at least a portion of the absorption material and (ii) an electrical potential difference applied between disparate locations within the absorption material.Type: GrantFiled: October 26, 2009Date of Patent: December 18, 2012Assignee: Schott CorporationInventor: Kevin Tabor

Patent number: 8291598Abstract: A retractable blade scraper includes a handle body having a handle rear end and a handle forward end including a forward-end opening. An internal blade-slide cavity extends rearwardly from the forward-end opening toward the handle rear end and is configured to selectively receive a blade through—the forward-end opening. A blade slide housed by the blade-slide cavity includes lower and upper blade slide members between which the blade is selectively retained. A blade-slide actuator is accessible through an actuator slot defined through a wall of the handle body between slot first and second ends. Reciprocation of the actuator between the slot first and second ends reciprocates the blade slide between a rearward blade-storage position in which the blade is housed in the blade-slide cavity and a forward blade-changing position in which the blade protrudes through the forward-end opening to facilitate blade changing.Type: GrantFiled: June 18, 2010Date of Patent: October 23, 2012Assignee: Hyde Tools, Inc.Inventors: Steven J.

Patent number: 8270762Abstract: A method of calibrating the intensity with which light is emitted through the light-emission face of an optical fiber light line assembly employs (i) a data processing system with computer memory, (ii) a camera communicatively linked to the data processing system, and (iii) a signal-responsive scoring device communicatively linked to the data processing system. Light is introduced into the assembly, an image of the emitting face is captured, and corresponding image data is stored in computer memory. The image data is segmented into plural image-data segments corresponding to physical sub-regions of the imaged face. The image-data segments are algorithmically analyzed to identify the sub-region that emits inputted light with the lowest intensity, and emission-intensity data associated with that sub-region is identified as reference emission data.Type: GrantFiled: July 18, 2009Date of Patent: September 18, 2012Assignee: Schott CorporationInventor: Robert E.

Patent number: 8017912Abstract: A method of classifying an electromagnetic-energy emitting source event as one of a first, second, and third class event includes registering an irradiance spectrum from the source event. The intensity of the energy emitted from the source event is measured within each of first, second and third energy sub-ranges and first, second and third relative-energy values are associated with, respectively, the first, second and third energy sub-ranges. A first class-eliminating determination is rendered by comparing to one another a first selected set of two of the relative-energy values, thereby yielding two remaining-candidate event classes. When necessary, a second class-eliminating determination renders the proper classification for the source event by comparing to one another a second selected set of relative-energy values including the relative-energy value not selected for inclusion in the first selected set of two relative-energy values and one of the previously selected relative-energy values.Type: GrantFiled: April 30, 2007Date of Patent: September 13, 2011Assignee: Solid State Scientific CorporationInventor: Richard J.
