Abstract
Abstract A countdown device such as a timer employing a digital display is providedith a plurality of up/down counters, one for each digit column. A single control switch is provided which may be in the form of a push-button and the signal obtained therefrom acts on each counter until a predetermined count is reached and then on the succeeding counter. Thereby digital data may be rapidly introduced, precision of the representation diminishing however as the interval increases.

Total Claims: 12
Claim 1
Independent Claim
211 words
A data introducing arrangement including a quantity measuring count-down digital display device for displaying a plurality of ordered columns of digits representative of the quantity, such as a timer, comprising: a multi-stage down counting means having a group of counting stages for each ordered digit column to be displayed, said multi-stage down counting means being set to a predetermined set count by activating stage groups of said multi-stage down counting means with setting pulses until said predetermined set count is reached, and said multi-stage down counting means measuring said quantity by thereafter counting downwardly, from said predetermined set count, pulses representative of said quantity; a setting pulse producing system for initially feeding setting pulses to a stage group corresponding to a lower order digit column when said multi-stage down counting means is being set at said predetermined set count; a logic means connected between said pulse producing system and said down counting means to block setting pulses fed to said stage group corresponding to said lower order digit column and to thereafter bypass said lower order stage group to feed said setting pulses to a stage group of a higher order digit column in response to said lower order stage group reaching a predetermined trigger count unrelated to said set count.

A data introducing arrangement including a quantity measuring count-down digital display device for displaying a plurality of ordered columns of digits representative of the quantity, such as a timer, comprising: a multi-stage down counting means having a group of counting stages for each ordered digit column to be displayed, said multi-stage down counting means being set to a predetermined set count by activating stage groups of said multi-stage down counting means with setting pulses until said predetermined set count is reached, and said multi-stage down counting means measuring said quantity by thereafter counting downwardly, from said predetermined set count, pulses representative of said quantity; a setting pulse producing system for initially feeding setting pulses to a stage group corresponding to a lower order digit column when said multi-stage down counting means is being set at said predetermined set count; a logic means connected between said pulse producing system and said down counting means to block setting pulses fed to said stage group corresponding to said lower order digit column and to thereafter bypass said lower order stage group to feed said setting pulses to a stage group of a higher order digit column in response to said lower order stage group reaching a predetermined trigger count unrelated to said set count.
Claim 3
Dependent Claim
22 words
A data introducing arrangement as in claim 1 wherein said logic means is coupled with all stage groups of the counting means.
Claim 4
Dependent Claim
49 words
A data introducing arrangement as in claim 2 wherein the lowest order counting stage group may register counts of 0-9 representing minutes, the succeeding counting stage group may register counts of 0-5 representing tens of minutes while thereafter succeeding counting stage groups may represent hours and tens of hours.
Claim 5
Dependent Claim
71 words
A data introducing arrangement as in claim 1 wherein a decoding means for decoding said count and providing electrical signals representative thereof is coupled between said lower-order counting stage group and said logic means and wherein a display means for displaying said count is also coupled to said decoding means whereby the count contents may be displayed and control signals generated to said logic means in accordance with said count contents.
Claim 6
Dependent Claim
92 words
A data introducing arrangement as in claim 4 wherein said logic means includes an input gating means for allowing pulses to flow to said lower order stage group when enabled, a bypass gating means for transmitting pulses around said lower order stage group to a higher order stage group when enabled and a latch circuit coupled between said input and bypass gating means and coupled to said decoding means, the state of the latch circuit and decoding means serving to determine the enabling of one or the other of said gating means.
Claim 7
Dependent Claim
46 words
A data introducing arrangment as in claim 5 wherein a futher input gating arrangement couples each successive counting stage group with the preceding lower order stage group, said further input gating arrangement being enabled when said counting means are set to measure said quantity by counting.
Claim 8
Dependent Claim
74 words
A data introducing arrangement as in claim 1 wherein the counting stage group corresponding to the lowest ordered digit column comprises four stages said logic means being associated with three of said four stages whereby an initial count of 0-9 may be registered followed by successive counts of 0 and 5 corresponding to the output of the fourth stage said counts representing minutes, while succeeding counting means may represent tens of minutes and hours.
Claim 9
Dependent Claim
24 words
A data introducing arrangement as in claim 1 wherein said count down device is incorporated into an electronic timepiece employing a quartz time standard.
Claim 10
Dependent Claim
14 words
A data introducing arrangement as in claim 8 wherein said timepiece is a wrist-watch.
Claim 11
Dependent Claim
25 words
A data introducing arrangement as in claim 1 wherein said setting pulse producing system and said logic means are actuated by a single on/off switch.
Claim 12
Dependent Claim
29 words
A data introducing arrangement as in claim 1 wherein said multi-stage down counting means counts upwardly when it is being set and downwardly when it is measuring said quantity.
