Abstract
An information retrieval system and method for determining the location of a traveller based upon a comparison between broadcast radiowave frequencies at the location and a table of locations for radio stations which broadcast at those radiowave frequencies. By determining the location, the offset hour for the time zone where the radio station is located may be obtained for correctly displaying the hour on an analog watch. When the watch is moved to a different time zone, the hands are accelerated, forward or backward, until they indicate the local time. The location, such as a city, can also be displayed so that the traveller is apprised of both the correct time and present location automatically.
Claims11
A portable timekeeping system comprising:
- means for determining the local time corresponding to the location of the system, said determining means producing an output signal;
- analog hands for indicating time;
- drive means for driving said hands;
- means for controlling said drive means to drive said hands at an accelerated rate until said hands indicate said local time, said controlling means being responsive to said signal;
- and
- means for determining the location of the system, said means for determining the location comprising:
- receiving means for receiving broadcast radiowave frequencies;
- storing means for storing information indicative of sets of radiowave frequencies which are transmitted from predetermined locations so that each set corresponds to a respective one of said predetermined locations;
- matching means for matching said received broadcast radiowave frequencies from said receiving means with a matching one of said sets of radiowave frequencies;
- and
- timekeeping means for updating time indicative of a local time where said received broadcast radiowave frequencies were transmitted based on matching from said matching means.
A method for time keeping, comprising the steps of:
- receiving broadcast radiowave frequencies from a plurality of locations;
- storing information indicative of sets of received radiowave frequencies that are transmitted from said locations so that each set corresponds to a respective one of said locations;
- receiving broadcast radiowave frequencies from a particular location;
- matching said received broadcast radiowave frequencies from said particular location with a matching one of said sets of radiowave frequencies;
- updating time indicative of a local time where said received broadcast radiowave frequencies from said particular location were transmitted based on the step of matching;
- and
- driving hands of an analog timepiece at an accelerated rate until said hands indicate the local time.
A portable timekeeping system, comprising:
- receiving means for receiving broadcast radiowave frequencies;
- storing means for storing information indicative of sets of radiowave frequencies which are transmitted from a plurality of particular locations so that each set corresponds to a respective one of said particular locations, said storing means being initially empty, said receiving means being activated at each of said particular locations and said storing means storing information indicative of the sets of received broadcast radiowave frequencies;
- matching means for matching said received broadcast radiowave frequencies from said receiving means with a matching one of said sets of radiowave frequencies;
- and
- timekeeping means for updating time indicative of a local time where said received broadcast radiowave frequencies were transmitted based on matching from said matching means.
