Portable programmable information device and external programming station
First Claim
1. A small-sized portable information system comprising a small-sized portable programmable information device including a first central processing unit, first memory means coupled to said first central processing unit for storing programs and data, first display means coupled to said first central processing unit, first input means coupled to said first central processing unit for the actuation thereof and a first power supply coupled to said first central processing unit, first memory means, first display means and first input means for powering same;
- a first external station including a second central processing unit, second memory means coupled to said second central processing unit for storing programs and data, second display means coupled to said second central processing unit, second input means coupled to said second central processing unit for the control thereof and a second power supply coupled to said second central processing unit, second memory means, second display means and second input means for powering same;
said first external station being adapted to receive a source program, said first external station including compiler means for compiling said source program, said source program being compiled by said compiler means and converted into an object program;
an interface means including a first interface means portion mounted on said portable information device and a second interface means portion mounted on said first external station, said first and second interface means portion being adapted, when coupled, to permit the transfer of said object program from said first external station to said first memory means of said portable information device to program said portable information device to perform said object program, and to permit the transfer of a plurality of data including alpha-numeric characters from said first external station to said first memory means of said portable information device, said portable information device being a wristwatch which includes timekeeping circuitry means for keeping actual constant time.

Abstract
A small-sized portable information system is provided including a small-sized portable information device and an external station. Both the external station and the portable information device are provided with a central processing unit, a memory device, a display device, an input device and a power supply. The portable information device and the external station can be coupled together by an electrical or optical interface to permit transfer of programs from the external station to the portable information device and exchange of data therebetween.
