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 tokens. The tokens include context information (indicating the identity of a nearby device and the services ― such as send/receive, scanning, printing, faxing, converting ― that are available a that device) are distributed from one person to another by transmission of IR data packets. Once a network-connected computer, printer or multifunction device has received a token via IR transceiver associated with it, a search request can be derived from the token and document references (e.g. WWW URLs) corresponding to the token can be obtained via a search engine. For each URL obtained, the corresponding electronic document can be retrieved from a repository and displayed or printed. The portable device is preferably a handheld or wristwatch computer with a graphical display for enabling the user to transfer tokens, and the fixed devices preferably include a scanner/copier/printer having its own IR transceiver.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
154 words
A method carried out in a data processing device including a processor, memory, a
user interface and means providing two way wireless communication with one or more other
devices, including a target device, comprising: (a) in response to a first user input defining a context request, transmitting a query, the
query requesting which service(s) can be performed by the target device, (b) receiving a response from the target device, the response incorporating a target device
identifier identifying the target device, and at least one component comprising a service identifier
identifying the service requested in step (a), (c) determining whether the response received in step (b) is positive, (d) if the response is positive, assembling a token from a plurality of token components,
each token component defining a document related entity and a property of the entity, at least one
component comprising the target device identifier, and at least one component comprising the
service identifier.
Claim 2
Independent Claim
124 words
A method carried out in a data processing device including a processor, memory,
and a user interface, comprising: (d) receiving a first user input designating a graphical object corresponding to a document,
the document being associated with a stored token, the token having a plurality of token
components, each token component defining a document related entity and a property of the entity,
at least one component comprising a target device identifier identifying the target device, and at
least one component comprising a service identifier identifying a service selected by the user. (e) receiving a second user input indicating that the token is to be sent to another data
processing device, (f) encoding the token in a data packet, and (g) transmitting the data packet.
Claim 3
Independent Claim
87 words
A method carried out in a data processing device including a processor, memory,
and a user interface, comprising: (h) receiving a data packet, (i) decoding the data packet to derive a token, the token from a plurality of token
components, each token component defining a document related entity and a property of the entity,
at least one component comprising a target device identifier identifying the target device, and at
least one component comprising a service identifier identifying a service, (j) storing the token derived in step (i).
Claim 4
Independent Claim
183 words
A method carried out in a data processing device including a processor, memory,
and a user interface and means providing two-way wireless communications with one or more
portable devices, the data processing device being couple in a network to one or more other data
processing devices, at least one of the data processing devices including means for storing a
repository of electronic documents, comprising: (h) receiving a data packet, (i) decoding the data packet to derive a token, the token having a plurality of token
components, each token component defining a document related entity and a property of the entity,
at least one token component comprising a request for a document related service, (j) assembling a service token from token derived in step (i), at least one component
comprising a target device identifier identifying the target device, and at least one component
comprising a service identifier identifying a service, said target device identifier and said service
identifier being dependent upon the location of said data processing device, (k) sending the service token to one of said other data processing devices via the network.
Claim 5
Independent Claim
184 words
A method carried out in a data processing device including a processor, memory,
and a user interface and means providing two-way wireless communications with one or more
portable devices, the data processing device being couple in a network to one or more other data
processing devices, at least one of the data processing devices including means for storing a
repository of electronic documents, comprising: (h) receiving a data packet, (i) decoding the data packet to derive a token, the token having a plurality of token
components, each token component defining a document related entity and a property of the entity,
at least one token component comprising a request for a document related service, and at least
one component comprising a target device identifier identifying the target device, and at least one
component comprising a service identifier identifying a service, said target device identifier and said
service identifier being dependent upon the location of said data processing device, (j) assembling a service token from token derived in step (i), (k) sending the service token to one of said other data processing devices via the network.
