Abstract
In accordance with the invention, a digital timepiece is provided with a mode of operation which presents a time message indicative of the approximate time. The mode can be implemented by adding to a digital timekeeping circuit, a digital conversion circuit to generate the messages. A visual display on the timepiece face displays the message. In a preferred embodiment the precise time can be displayed as an alternative mode.
Description




FIELD OF THE INVENTION




This invention relates to timepieces such as watches and clocks and, in particular, to an improved digital timepiece adapted to provide messages indicative of the approximate time.




BACKGROUND OF THE INVENTION




Timepieces are now accurate and precise beyond usual human need. Inexpensive digital watches, for example, can display time to a tenth or even a hundredth of a second periods too short for human response. Moreover displays of such precision can, at a quick glance, be readily misinterpreted. For example, a quick glance at 12:58 may focus on the 12 without the recognition that the time is much closer to 1:00 than to 12:00.




Analog watches are easier to interpret, but suffer from mechanical problems and are expensive to make. They are difficult to read under low-light conditions and mistakes are made in matching hour hand with the hour tick-mark on the face. Accordingly there is a need for a timepiece provided with an approximate time message readily interpretable upon a quick glance.




SUMMARY OF THE INVENTION




In accordance with the invention, a digital timepiece is provided with a mode of operation which presents a time message indicative of the approximate time. The mode can be implemented by adding to a digital timekeeping circuit, a digital conversion circuit to generate the messages. A visual display on the timepiece face displays the message. In a preferred embodiment the precise time can be displayed as an alternative mode.

DETAILED DESCRIPTION




Referring to the drawings,

FIGS. 1A

,


1


B, and


1


C are schematic views of an exemplary timepiece


10


in accordance with the invention presenting different approximate time messages.

FIG. 1A

illustrates a timepiece (here a watch) providing an approximate time message. The timepiece


10


is preferably in the form of a digital watch including a face


11


, an attachment mechanism such as a wrist band


12


(or a ring band or a neck band), a set button


13


and a mode button


14


. In a preferred form, the timepiece includes a display


15


for displaying a near hour in the center of face


11


and includes displays


16


A,


16


B above and below the hour display to provide text messages. The combination of text and hour provides an approximate and appropriate measure of the current time that can be readily interpreted at a quick glance.

FIG. 1A

, for example, indicates about 3:00.

FIG. 1B

shows approximately noon, and

FIG. 1C

indicates about 3:30. By approximate time, it is meant that the same message will apply over a period of at least five minutes. In a preferred form, the timepiece also retains the conventional precise time mode as an alternative that the user can access via mode button


14


. By precise time, it is meant that the time is separately indicated for each minute or less.




The subject timepiece can be achieved, for example, by providing conversion functionality to a conventional digital clock timing circuit

FIG. 2

schematically illustrates a circuit


20


provided with such functionality. In essence a digital timekeeping circuit unit


21


is switched by mode switch


14


between driving a conventional display


23


or providing an input to a conversion unit


24


which, in turn, activates an approximate time display driver


25


. Typical conversion functionality is illustrated in table 1, below.

Typical time intervals for approximation can range from 5 to 10 minutes, and the intervals are advantageously shorter near the hour. In preferred form the mode switch is normally on the approximate time messaging. The conventional precise time display can be temporarily accessed by pressing the mode button.




The conversion unit


24


can be in the form of digital circuitry or largely in the form of software. In its simplest form, it is essentially a look-up table responsive to the output of the digital timekeeping circuit. In response to a timekeeping signal falling within each chosen interval, the conversion unit activates the displays to provide a predetermined approximate time message such as exemplified in table 1.





FIG. 3

provides an implementation of an exemplary unit


24


.




The mode and set switch can allow access to a multiplicity of functions. For example, the watch may be designed for the global market. In this case, by repeatedly pressing the mode switch it cycles the language of the displayed approximate time—e.g. among English, Spanish, and Japanese, Pressing the “set” button can select that particular language for display, until changed again with the mode button.




Alternatively, the watch may display all messages in English, but vary the style and tone of each message. For example, one grouping of messages might be in plain English, as in Table 1. Another grouping might be inspired by movies—e.g. “About Noon” replaced with “High Noon”, and “About Midnight” with “Midnight Cowboy”. Yet another grouping might adapt to regional slang, and so on. Again, the mode and set buttons are used to cycle and select a grouping for display.




Some messages might repeat only once a year—e.g. “Happy New Year” at midnight January 1, or “Happy Anniversary”, displayed all day on your wedding anniversary.




It is understood that the above-described embodiments are illustrative of only a few of the many possible specific embodiments, which can represent applications of the invention. Numerous and varied other arrangements can be made by those skilled in the art without departing from the spirit and scope of the invention.
