Patent ID: 7034999

Claim:
A method, performed by a retail purchaser of a previously-purchased remote-controlled retail electronic entertainment device, for retro-fitting said remote-controlled device to provide an increased acceptance angle for an infrared receiver thereof, the method comprising the steps of: purchasing, on a retail basis and subsequent to a previous purchase of said remote-controlled device, a hemispheric lens, the hemispheric lens comprising a lens body, the lens body being fabricated from a dielectric material substantially transparent at an infrared wavelength received by the infrared receiver, the lens body having a substantially hemispheric convex outer surface, a substantially hemispheric concave inner surface, a substantially flat annular surface connecting the inner and outer hemispheric surfaces, and an adhesive layer comprising double-sided adhesive tape provided on the annular surface for securing the lens to a face of the remote-controlled retail electronic entertainment device over the infrared receiver thereof; and after purchasing the hemispheric lens, securing the hemispheric lens to the face of the previously-purchased remote-controlled retail electronic entertainment device over the infrared receiver thereof, thereby increasing the acceptance angle over which infrared remote control signals may be received by the infrared receiver, wherein the remote-controlled retail electronic entertainment device is a television, a video cassette recorder, a video cassette player, a DVD player, a DVD recorder, a cable television receiver, a satellite television receiver, a radio, a stereo, a hi-fi system, an audio cassette player, an audio cassette recorder, an audio CD player, an audio CD recorder, a home theatre system, a surround-sound system, an MP3 player, an MP3 recorder, a DVD-audio player, or a DVD-audio recorder.
