Abstract
Abstract A digital display arrangement is provided for balanced general timekeeping having centrally-positioned hour digits and two sets of smaller, equal-sized minute digits flanking the hour digits for trailing and leading readout, with hockey stick-shaped display elements positioned below the minute digits and oriented to give graphic symbols of minutes increasing past the present hour and minutes decreasing toward the next hour, respectively. Means are provided for blanking the hour digits and simultaneously energizing a chronograph time display which, because of resulting large spaces uniquely seen only between the chronograph digits, presents substantial visual contrast from, and minimum potential for ambiguity or confusion with, the general timekeeping mode.

Claim 4
Dependent Claim
80 words
A display as in claim 1 in which the background comprises at least two zones which differ in size and shape, a first one of the zones being generally rectangular, horizontally oriented and containing the hour, minute and hockey stick-shaped elements, a second one of the zones being generally square shaped, substantially smaller in size than the first zone and located below the center of the first zone, the second zone containing seconds elements operable for display of seconds digits.
Claim 5
Dependent Claim
35 words
A display as in claim 3 in which the overall sizes of the digits differ in the order of the hour digits being the largest, the minute digits smaller, and the seconds digits the smallest.
Claim 6
Dependent Claim
70 words
A display as in claim 3 operable to display initially a present hour digit and trailing minute digits increasing from zero to thirty during the first half of such hour, and thereafter the next hour digit and leading minute digits decreasing from twenty-nine back toward zero during the second half of the same hour, and with the seconds digits progressing up and down between zero and thirty during each minute.
Claim 7
Dependent Claim
55 words
A display as in claim 3 in which the background includes a third zone above the first zone, the third zone being generally rectangular, horizontally oriented and narrower in width and height than the first zone, the third zone containing elements operable to display abbreviated names of the days of the week and the date.
Claim 8
Dependent Claim
56 words
A display as in claim 6 in which the abbreviations comprise the first three letters of each day, with each set of letters being in vertical alignment and placed in SUN-to-SAT left-to-right horizontal order followed by the date in the third zone, and being operable to display each day separately while the other days remain blank.
Claim 9
Dependent Claim
19 words
A display as in claim 7 which includes a horizontal line separating the third zone from the first zone.
Claim 10
Dependent Claim
114 words
A balanced general timekeeping and chronograph timekeeping digital display which comprises: (a) a display background; (b) hour elements operable for display of hour digits at substantially a central position within the background during general timekeeping; (c) first minute elements operable for display of minute digits in a readout position which trails the hour digits from left to right during general timekeeping; (d) second minute elements operable for display of minute digits in a readout position which leads the hour digits from left to right during general timekeeping; and (e) means for blanking the hour digits and energizing both the leading and trailing minute digits for display of minutes and seconds, respectively, during chronograph timekeeping.
Claim 11
Dependent Claim
114 words
