Data communication system for hand-held computers
First Claim
1. A docking apparatus for a plurality of hand-held computers having optical data ports, comprising:
- a plurality of docking bays, a central processing unit, optical transmitting means connected to the central processing unit for transmitting data to the docking bays, and optical receiving means connected to the central processing unit far receiving data from the docking bays;
the transmitting and receiving means including light guides adapted to carry the data between the central processing unit and the data port of each computer in its respective docking bay, in which each light guide comprises at least one rod of transparent material having a series of branches which are adapted to communicate with individual bays of the housing positioned at different distances from the CPU, and in which each light guide comprises at least one rod of flattened cross-section, each branch being arranged to extend outwardly from the flattened region, and having a width which is less than the width of the rod, whereby a light beam passing through the rod is only partially diverted into the branch.

Abstract
A docking apparatus for a plurality of hand-held computers having optical data ports is provided. The docking apparatus includes a plurality of docking bays, a central processing unit, an optical transmitting communication path connected to the central processing unit for transmitting data to the docking bays, and an optical receiving communication path connected to the central processing unit for receiving data from the docking bays. The transmitting and receiving communication paths include light guides adapted to carry the data between the central processing unit and the data port of each computer in its respective docking bay.
