Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
82 words
An optically coupled data interface comprising: a host device having means to receive data in optical format and having means to impart optical data initiating signals; a portable module having means to optically interface with said host device and having an optically responsive window (adapted to receive) for receiving optical (data initiating) signals from said host device; and means self contained in said portable module for controlling said optically responsive window to impart data onto optical signals receivable by said host device.
Claim 2
Dependent Claim
82 words
An optically coupled data interface comprising: a host device having means to receive data in optical format and having means to impart optical data initiating signals; a portable module having means to optically interface with said host device and having an optically responsive window (adapted to receive) for receiving optical (data initiating) signals from said host device; and means self contained in said portable module for controlling said optically responsive window to impart data onto optical signals receivable by said host device.
Claim 3
Dependent Claim
38 words
An optically coupled data interface according to claim 1 wherein said module is in the form of thin, relatively flat a member adaptable for convenient on-person carriage such as in the pocket, billfold or purse of a user.
Claim 4
Dependent Claim
23 words
An optically coupled data interface according to claim 1 wherein said optically responsive window is in the form of a controllable optical shutter.
Claim 5
Dependent Claim
23 words
An optically coupled data interface according to claim 1 wherein said optically responsive window is in the form of a controllable optical reflector.
Claim 6
Dependent Claim
22 words

Claim 7
Dependent Claim
48 words
An optically coupled device according to claim 1 wherein said optically responsive window is in the form of a plurality of windows each adapted to sumultaneously receive optical data initiating signals from said host device and for individually imparting data onto optical signals receivable by said host device.
Claim 8
Dependent Claim
45 words
An optically coupled data interface according to claim 1 wherein said module contains a photovoltaic element adaptable to receive light from said host device when said module and host device are interfaced, said photovoltaic element providing electrical energy for operation of said optically responsive window.
