Abstract

A multipurpose pregnancy and labor timing device for use by expectant parents during the gestation, labor, and birth of their child. The timing device includes an output device for conveying a plurality of datum to a human ovserver. The datum conveyed may represent a current time, day and date, an expected date of birth of the child, an estimated elapsed time period since the conception date of the child, an estimated time period until the birth of the child, the count of contractions experienced by a woman undergoing the process of labor, the time interval between contractions, the duration of a contraction, and the actual time and date of the birth of the child. The timing device also includes a nonvolatile memory for storing at least some of the plurality of datum, a data selection device for selecting at least some of the plurality of datum for conveyance by the output device, and a data initialization device for initializing the first datum and the second datum. The timing device further includes a processor control device for performing a first sequence of operations to store at least some of the plurality of datum into the nonvolatile memory, for performing a second sequence of operations to retrieve at least some of the plurality of datum from the nonvolatile memory so that at least some of the plurality of datum is conveyed by the output device, and for calculating at least some of the plurality of datum.

Claims

1. A multipurpose pregnancy and labor timing watch, said watch comprising:

(a) output means for displaying a plurality of information, said output means including a plurality of alpha-numeric displays and said output means having a plurality of selectively-chosen display modes;

said information including;

i. a current time, a current date, and a current weekday;

ii. an expected due date for birth of a child;

iii. an elapsed time since an estimated conception of the child;

iv. an estimated time until the expected due date for birth of the child;

v. a count of contractions during birth of the child;

vi. a time interval between contractions during birth of the child;

vii. a duration of contractions during birth of the child;

viii. a recorded birth time, birth date, and birth weekday;

said plurality of display modes including;

i. a first mode in which said output means simultaneously displays the current time, the current date, the current weekday, and the expected due date for birth of the child;

ii. a second mode in which said output means simultaneously displays the elapsed time since the estimated conception of the child and the estimated time until the expected due date for birth of the child;

iii. a third mode in which said output means simultaneously displays the count of contractions during birth of the child, the time interval between contractions during birth of the child, the duration of contractions during birth of the child, and the current time;

iv. a fourth mode in which said output means simultaneously displays the recorded birth time, birth date, and birth weekday;

(b) nonvolatile memory means for storing said at least some of said information;

(c) processor control means for controlling said output means, for storing at least some of said information in said nonvolatile memory means, and for calculating other of said information from said stored at least some of said information;

(d) mode selection means for selectively choosing one of said plurality of display modes for said output means;

(e) data initialization means for initializing said watch for said stored some of said information;

said mode selection means, when said fourth mode is entered, causing the recorded birth time, birth date, and birth weekday to be freezingly preserved by said processor means from the current time, the current date, and the current weekday, respectively.

2. The multipurpose pregnancy and labor timing watch as recited in claim 1, in which said watch additionally includes tone generator means for playing a preselected song when said fourth mode is entered.
