Abstract
Abstract A system including any number workstations, file servers, printers and other fixed devices coupled in a network, and a number of portable devices carried by users and coupled to the network by infrared (IR) link. Each portable device emulates its user's personal satchel for documents: the device is programmed to receive transmit and store document references or tokens, each of which is associated with an electronic document stored in the database. Documents are distributed from one person to another by transmission of document references or tokens, and a document is sent to a printer by beaming that document's reference or token to an IR transceiver associated with that printer. The portable device is preferably a handheld or wristwatch computer with a graphical display for enabling the user to transfer documents, and the fixed devices preferably include a scanner/copier/printer having its own IR transceiver.

Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
178 words
A system for communicating with a portable electronic document reference transport device, the portable electronic document reference transport device having a memory for storing document references, said system comprising: a wire-based network for providing a communications link between devices coupled thereto; a transceiver coupled to said wire-based network for establishing a wireless communications link with the portable electronic document reference transport device and devices coupled to said wire-based network; a subsystem coupled to said wire-based network and communicating with said transceiver; said subsystem being adapted to operate a database that associates electronic document references with electronic documents; each electronic document reference identifying a location of a single electronic document stored in a memory on a device operating on said wire-based network; said subsystem receiving, from said transceiver, a communication originating from the portable electronic document reference transport device; the communication including an electronic document reference that is associated with a selected electronic document and a request for a service provided by a device coupled to the wire-based network that is to be performed on the selected electronic document.
Claim 2
Independent Claim
178 words
A system for communicating with a portable electronic document reference transport device, the portable electronic document reference transport device having a memory for storing document references, said system comprising: a wire-based network for providing a communications link between devices coupled thereto; a transceiver coupled to said wire-based network for establishing a wireless communications link with the portable electronic document reference transport device and devices coupled to said wire-based network; a subsystem coupled to said wire-based network and communicating with said transceiver; said subsystem being adapted to operate a database that associates electronic document references with electronic documents; each electronic document reference identifying a location of a single electronic document stored in a memory on a device operating on said wire-based network; said subsystem receiving, from said transceiver, a communication originating from the portable electronic document reference transport device; the communication including an electronic document reference that is associated with a selected electronic document and a request for a service provided by a device coupled to the wire-based network that is to be performed on the selected electronic document.
