Method of displaying elapsed time on a wristworn device and wristworn device displaying same
Methodologies and constructions of displaying elapsed time on a wristworn device, which include among other things, having at least two display hands one of which that will rotate faster or stop so that they become coincident with each other, then rotate together and then reassume their normal and accurate positions. Such is particularly important with respect to one of the hands that is preferably a seconds hand that might otherwise be displaying seconds of the time of day (“TOD”).
1. A method of displaying elapsed time on a display of a wristworn device, wherein the wristworn device comprises said display, at least one rotatable display hand for displaying elapsed time, a rotatable seconds hand for displaying elapsed time related to the time of day (TOD), and wherein rotation of the at least one display hand can be initiated and terminated, and wherein during a first mode the seconds hand is rotating about the display at a first rate, the method comprises the steps of:
starting the rotation of the at least one display hand;
stopping the rotation of the seconds hand until the at least one display hand and the seconds hand are coincident;
starting the rotation of the seconds hand so that the seconds hand and the at least one display hand rotate together at the first rate so that it appears as if there is only one hand rotating;
stopping the rotation of the at least one display hand; and
thereafter, rotating the seconds hand at a rate faster than the first rate until the seconds hand reaches a position at which the seconds hand would have been had it not been stopped; and then
causing the seconds hand to rotate about the display at the first rate.
2. The method as claimed in claim 1 , wherein:
the first mode is the normal “run” mode;
the at least one display hand is started when the wristworn device enters a “chrono” mode;
the seconds hand displays elapsed seconds; and
the first rate is a TOD seconds hand rotation rate.
3. A wristworn device that displays elapsed time on a display, wherein the wristworn device comprises:
at least one rotatable display hand for displaying the elapsed time;
a rotatable seconds hand for displaying elapsed seconds related to the time of day (TOD),
a switching arrangement for initiating and terminating a rotation of the at least one display hand; and
a controller, operatively coupled to the switching arrangement, for carrying out the methodology as claimed in claim 1 .
4. A method of displaying elapsed time on a display of a wristworn device, wherein the wristworn device comprises said display, at least one rotatable display hand for displaying elapsed time, a rotatable seconds hand for displaying elapsed time related to the time of day (TOD), and wherein rotation of the at least one display hand can be initiated and terminated, and wherein during a first mode the seconds hand is rotating about the display at a first rate, the method comprises the steps of:
starting the rotation of the at least one display hand;
advancing the rotation of the seconds hand at a rate faster than the first rate until the seconds hand and the at least one display hand are coincident, and then causing the seconds hand to return to rotate about the display at the first rate;
continuing the rotation of the seconds hand so that the seconds hand and the at least one display hand rotate together at the first rate so that it appears as if there is only one hand rotating;
stopping the rotation of the at least one display hand; and
stopping the rotation of the seconds hand until the seconds hand is at a position at which the seconds hand would have been had it not advanced at the rate faster than the first rate; and then
causing the seconds hand to rotate about the display at the first rate.
5. The method as claimed in claim 1 , wherein:
the first mode is the normal “run” mode;
the at least one display hand is started when the wristworn device enters a “chrono” mode;
the seconds hand displays elapsed seconds; and
the first rate is a TOD seconds hand rotation rate.
6. A wristworn device that displays elapsed time on a display, wherein the wristworn device comprises:
at least one rotatable display hand for displaying the elapsed time;
a rotatable seconds hand for displaying elapsed seconds related to the time of day (TOD),
a switching arrangement for initiating and terminating a rotation of the at least one display hand; and
a controller, operatively coupled to the switching arrangement, for carrying out the methodology as claimed in claim 4 .
7. A wristworn device that displays elapsed time on a display, wherein the wristworn device comprises:
at least one rotatable display hand for displaying the elapsed time;
a rotatable seconds hand for displaying elapsed seconds related to the time of day (TOD), wherein during a first mode, the seconds hand rotates about the display at a TOD seconds hand rotation rate;
a switching arrangement for initiating and terminating a rotation of the at least one display hand; and
a controller, operatively coupled to the switching arrangement, for:
initiating the rotation of the at least one display hand;
stopping the rotation of the seconds hand until the at least one display hand and the seconds hand are coincident;
starting the rotation of the seconds hand so that the seconds hand and the at least one display hand rotate together at the TOD seconds hand rotation rate so that it appears as if there is only one hand rotating;
terminating the rotation of the at least one display hand; and
thereafter, causing the rotating of the seconds hand at a rate faster than the TOD seconds hand rotation rate until the seconds hand reaches a position at which the seconds hand would have been had it not been stopped; and then
causing the seconds hand to rotate about the display at the TOD seconds hand rotation rate.
8. A wristworn device that displays elapsed time on a display, wherein the wristworn device comprises:
at least one rotatable display hand for displaying elapsed time;
a rotatable seconds hand for displaying elapsed seconds related to the time of day (TOD), wherein during a first mode, the seconds hand rotates about the display at a TOD seconds hand rotation rate;
a switching arrangement for initiating and terminating a rotation of the at least one display hand; and
a controller, operatively coupled to the switching arrangement, for:
initiating the rotation of the at least one display hand;
causing the rotating of the seconds hand at a rate faster than the TOD seconds hand rotation rate until the seconds hand and the at least one display hand are coincident, and then causing the seconds hand to return to rotate about the display at the TOD seconds hand rotation rate;
providing for the continued rotation of the seconds hand so that the seconds hand and the at least one display hand rotate together at the TOD seconds hand rotation rate so that it appears as if there is only one hand rotating;
terminating the rotation of the at least one display hand; and
stopping the rotation of the seconds hand until the seconds hand is at a position at which the seconds hand would have been had it not advanced at the rate faster than the TOD seconds hand rotation rate; and then
causing the seconds hand to rotate about the display at the TOD seconds hand rotation rate.
