Abstract

A fertility indicator for storing a plurality of time measurements between consecutive menstrual periods by using a plurality of hours as a unit of count to optimize time measurements and output displays. The indicator uses a computer to analyze the menstrual cycles variables, by applying the Ogino'"'"'s method and in combination with ovulation cycle variables, to project the fertile status for the present cycle, and by treating all of the stored cycles as the length of the present cycle, the fertile extensions are a true representation of user'"'"'s cycle history in an ever renewing state as new data erases the oldest stored data. Arrangements are provided for data input protection and data retention.

Claims

1. A fertility computer comprising:

a numeric keyboard having means for manually inputting times of occurrence of menstrual cycles of a user;

storage means for storing a plurality of the times of occurrence of menstrual cycles most recently input via said inputting means;

data processing means responsive to the times of occurrence of menstrual cycles stored in said storage means for providing the user with her current fertility status;

display output means for outputting user fertility status,

said display means comprising means responsive to said data processing means for displaying first and second different displays corresponding to fertile and non-fertile statuses, respectively; and

means responsive to a single predetermined input via said keyboard for controlling said display means to selectively display said first and second displays, whereby the display of said first and second displays corresponds to the user'"'"'s fertility status at successive times,

said fertility computer further comprising a casing having a battery compartment extending linearly through said casing, said compartment having opposed openings for receiving an operating battery and ejecting said battery, and a battery in said compartment having sliding contacts for maintaining uninterrupted power to said computer when exchanging batteries,

said battery having a locking key for preventing the battery from being pushed out of said compartment by any other object than another battery cartridge having same key design.

2. In a fertility computing device having a computer for measuring and analyzing data which is indicative of user fertile status, the improvement comprising;

(a) a housing;

(b) an electrical power source inside said housing;

(c) switch means mounted on said housing and coupled to said computer for entering a user personal access code to indicate the commencement of the user'"'"'s menstrual period, for entering data, and for entering requests to display fertility status, and

first and second display means for indicating fertile and non-fertile status, respectively

said computer comprising means responsive to a receipt of a request from said switch means for indicating fertile and non-fertile status by sequentially energizing said first and second display means to display fertility statuses of the user for successive equally spaced apart times, said power source comprising a battery cartridge having a key shaped portion, and further including a built-in battery compartment for accepting said battery cartridge, said compartment having locking key means and sliding contacts for maintaining uninterrupted power when exchanging battery cartridges, said locking key means preventing the battery cartridge from being pushed out from the housing by any other object except by another battery cartridge having a recess matching the shape of said key shaped portion.

3. A battery powered computer system comprising a housing, a computer in said housing, said housing having an opening extending therethrough for receiving a battery cartridge, and a first battery cartridge in said opening, said cartridge having terminals in the form of sliding contacts on the sides thereof, said opening having sliding contacts for engaging the sliding contacts of the cartridge for energizing said computer, said housing having a latch arrangement for holding said cartridge in said opening, said latch being releasable by the engagement thereof with a second cartridge of the same shape as said first mentioned cartridge for replacement of said first mentioned cartridge.

4. The computer system of claim 3 wherein said first mentioned cartridge has a key shaped projection on one end thereof, and a recess on the end opposite said one end and having the same shape as said key shaped projection.
