| 20080251699 | METHOD AND SYSTEM FOR WAVELENGTH-DEPENDENT IMAGING AND DETECTION USING A HYBRID FILTER - Apparatus and methods for wavelength-dependent detection are provided. A detector includes a hybrid filter having unpatterned and patterned filter layers and at least one light-detecting sensor that detects light in first and second wavelength bands from the patterned filter layer of the hybrid filter. The unpatterned filter layer passes light in two nonoverlapping wavelength bands relative to light in wavelength bands between or among the nonoverlapping wavelength bands. The patterned filter layer includes first and second regions configured respectively to pass light in the first and second wavelength bands of the nonoverlapping wavelength bands passed by the unpatterned filter layer. | 10-16-2008 |

| 20100001950 | POSITION DETERMINATION UTILIZING A CORDLESS DEVICE - A system for generating position information includes a reflector, an image collection system, and a processor. The image collection system is configured to collect at least two sets of image data, where one set of image data includes a stronger indication of the reflector than the other set of image data. The two sets of image data can be collected in many different ways and may include using a retroreflector as the reflector. The two sets of image data are used to generate position information related to the reflector. In particular, position information related to the reflector is generated by taking the difference between the two set of image data. Because one set of image data includes a stronger indication of the reflector than the other set of image data, the difference between the two sets of image data gives a definitive indication of the reflector's position. | 01-07-2010 |
