Timepiece with speed adjustment for time standard change adaptation
First Claim
1. In a timepiece for continuously advancing an indication of time at a standard rate, an improvement for assisting a user to accommodate to a change, over a given adaptation period, from one time standard originally applicable to said user, to another different time standard, subsequently applicable to said user, comprising:
- input means for supplying to said timepiece, control data representing at least two of the following;
said one time standard originally applicable to said user, said other time standard, subsequently applicable to said user, said adaptation period, and a desired operation rate for said timepiece;
storage means for storing data representing at least two of the following;
the time under said original time standard, the time under said other time standard, said adaptation period, and said operation rate;
calculation means, responsive to said data in said storage means, for automatically calculating and supplying, during said adaptation period, output data representing a non-standard rate of advance of time for said timepiece based upon said control data, such that said non-standard rate of advance will correspond to the rate at which time would progress if the time standard experienced by said user gradually changed during said adaptation period from said original time standard to said other time standard;
display means, responsive to said output data of said calculation means, for indicating time to said user at said non-standard rate during said adaptation period,such that the time indicated by said timepiece varies gradually during said adaptation period, between the time under said original time standard and the time under said other time standard, and such that said user by observing said timepiece during said adaptation period, will tend to become gradually psychologically adapted to the time under said other time standard or that said user can change the indicated advancement of time of other purposes.

Abstract
An electronic watch includes a "traveler'"'"'s time" function which can be activated when a wearer leaves on a long trip, east or west by plane, boat or the like. This function will advance or retard the operation rate of the watch so that after a user-determined trip time has elapsed, the watch will display the actual local time at the arrival location, and the watch will resume operation at its normal rate. By glancing at the watch from time to time, a traveler can become accustomed gradually to a time change caused by his travel through different time zones so that the psychological effects of "jet lag" are minimized. The watch may also be used by a non-traveler to cause time to advance at a non-standard rate for other reasons. The watch includes a microprocessor (10), a quartz crystal (20) for providing a time standard, a display (30) for displaying the time, and a set of switches (40-90) for activating the watch'"'"'s functions. The microprocessor includes a set of registers (145 to 160) for storing the departure, destination, operation rate, and traveler'"'"'s times, and for controlling operation of the watch.

9. A timepiece for a user experiencing at least one change of time standards, from one time zone to a different time zone, within a given adaptation period, comprising:
-
clock means for producing a normal time signal representing the progression of time at a normal rate; storage means arranged to receive said normal time signal and input data representing (1) a time correction for the time difference between said two time zones, (2) the direction of said time correction, and (3) said given adaptation period; calculation means arranged to produce a modified time signal having a frequency which is greater or lesser than that of said normal time signal by an amount determined by said time correction and said given adaptation period; loading means for loading said input data into said storage means; display means responsive to said normal and said modified time signals for displaying time; and selection means for selectively applying said normal time signal and said modified time signal to said display means so that said modified time signal is applied to said display means during said adaptation period, whereby the time displayed by said display means will gradually change to effect said time correction in a gradual manner over said adaptation period, such that said user, by observing said timepiece during said adaptation period, will tend to become gradually psychologically adapted to the time under said different time zone standard or that said user can change the indicated advancement of time for other purposes. - View Dependent Claims (10, 11)

12. A timepiece for a user experiencing a change of time standards during a given adaptation period, from one time zone standard to a different time zone standard, comprising:
-
display means responsive to a time signal for displaying time represented by said time signal; processing means connected to provide a plurality of time signals to said display means, one of said time signals being a normal time signal representing time advancing at a normal test as would be experienced by a person not experiencing a change of applicable time standards; another of said time signals being a modified signal representing time advancing at a modified rate as would be required to adjust, in said given adaptation period, the time standard from that in said one time zone to that in said different time zone; data entering means arranged to enter control data into said processing means representing at least two of the following;
said change in time standards, said given adaptation period, and said modified rate; andselection means arranged to cause said display means to display the time represented by said modified time signal during said adaptation period, and said normal time signal thereafter, whereby the time displayed by said display means will change gradually to effect said time correction in a gradual manner over said adaptation period, such that said user, by observing said timepiece during said adaptation period, will tend to become gradually psychologically adapted to the time under said different time zone standard or that said user can change the indicated advancement of time of other purposes. - View Dependent Claims (13, 14, 15, 16)
