The appellant discloses techniques for automatically updating a time piece when the boundary of a time zone is crossed. More specifically, stored data defining time zone boundaries are combined with location data from a Global Positioning Satellite receiver to decide when a time zone boundary is crossed. Alternatively, current time data are transmitted to a timepiece from transmitters at locations frequented by travelers, e.g., railroad stations, bus terminals, and airports. Claim 4, which is representative for our purposes, follows: 4. A timepiece which can be remotely updated, comprising: a. a clock, and b. a receiver configured to receive externally supplied update information over a communications link for updating said clock in which said update information is provided from a vehicle.Page: Previous 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 NextLast modified: November 3, 2007
