Abstract: An eyeglass interface device includes a camera section, a wireless communication section, and a power generation section. The camera section acquires the image of the retina of an eyeball of a user, and outputs the imaging signal thereof to the wireless communication section. The wireless communication section transmits the imaging signal from the camera section by a radio wave. The power generation section supplies power to the camera section and the wireless communication section. The eyeglass interface device preferably includes a display section for displaying, on eyeglass lenses, image information sent from a mobile phone or the like to the wireless communication section, and an audio section having a bone conduction earphone and a microphone.

Abstract: A polishing method characterized by measuring the thickness of a film of a monitoring piece to be polished which is to be used exclusively for monitoring polishing amount, and obtaining polishing amount on the basis of the results of measurement, and judging, on the basis of the resulting polishing amount, setting/change of polishing condition of a polishing object, whether it is necessary or not to replace a polishing pad, and/or completion of run-in polishing after replacement of the polishing pad, and an apparatus to be used for practicing same.
