Publication number: 20130292585Abstract: This invention provides for a removable/replaceable, wavelength-transforming sleeve/sheath to be placed around a primary UV radiation source that emits a primary UV wavelength spectral distribution; such that at least a portion of the sleeve/sheath transforms at least a portion of the primary UV wavelength spectral distribution to a different secondary wavelength spectral distribution. Additionally, the sleeve/sheath may help to prevent breakage of the primary UV radiation source and to contain the broken pieces in the event of breakage. In some embodiments, a portion of the sleeve/sheath may be coupled with a UV reflective surface to direct radiation in a preferred direction. Individual sleeves/sheaths may have various patterns of wavelength-transforming materials that emit one or more secondary wavelength spectral distributions and the sleeve/sheath may also have one or more sections that allow transmission of the primary UV wavelength spectral distribution.Type: ApplicationFiled: February 17, 2013Publication date: November 7, 2013Inventor: William G.

Patent number: 6243476Abstract: A system for generating loudspeaker-ready binaural signals comprises a tracking system for detecting the position and, preferably, the angle of rotation of a listener's head; and means, responsive to the head-tracking means, for generating the binaural signal. The system may also include a crosstalk canceller responsive to the tracking system, and which adds to the binaural signal a crosstalk cancellation signal based on the position (and/or the rotation angle) of the listener's head. The invention may also address the high-frequency components not generally affected by the crosstalk canceller by considering these frequencies in terms of power (rather than phase). By implementing the compensation in terms of power levels rather than phase adjustments, the invention avoids the shortcomings heretofore encountered in attempting to cancel high-frequency crosstalk.Type: GrantFiled: June 18, 1997Date of Patent: June 5, 2001Assignee: Massachusetts Institute of TechnologyInventor: William G. Gardner
