Wheels of Zeus (or WoZ) was a company founded in 2002 by Apple co-founder Steve Wozniak. WoZ made wireless hardware for keeping track of the physical location of enabled objects. The licensable technology consisted of three components: # Smart Tag A tag containing GPS that could be attached to various objects, such as a brief case or pet. "Acceptable areas" could be preprogrammed, such that the tag would signal the Tag Detector when it was moved outside them. The tag communicated over a wireless network named "wOzNet" and used GPS techniques to transmit the tag's position over extreme distances with very little power. # Tag Detector This was a handheld device that could monitor a collection of Smart Tags, and provide a distance and direction to help locate them when they were lost. It also communicated with the wOz Service when a Smart Tag was lost. # WoZ Service An internet based service that could provide the locations of the various Smart Tags, as well as send an email or SMS notification when a Smart Tag moved outside of its "acceptable area". In March 2006, Wheels of Zeus shut down operations. Some assets and patents were acquired by ZonTrak. ==References== 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Wheels of Zeus」の詳細全文を読む スポンサード リンク
