A camera can be used to record multiple low resolution images of an object by shifting a camera lens relative to an image sensor of the camera. Each camera image recorded represents a portion of the object. A composite high resolution image of the object can be obtained by patching together the camera images by using various well known mosaicing, tiling, and/or stitching algorithms.

Mosaicing images with an offset lens

A system is presented for transmitting document references or tokens between users of integrated wireless and wire-based communication services. The system includes workstations, files servers, printers and other devices coupled to a wire-based network. Mobile computing devices are coupled to the wire-based network through either IR (infrared) or RF (radio) transceiver gateways. Each mobile computing device appears to hold a user's collection of documents: the device is programmed to receive, transmit, and store document tokens. The system includes a token-enabled document server that uses digital signatures to provide secure transfer of document tokens between users of the mobile computing devices and email clients. The token-enabled document server operates independent of the identity of the holder of the document token. Only the issuer of the document token needs be registered with the signature based document server to properly authenticate document tokens.

Secure token-based document server

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 or service tokens (tokens). Preferably, the token comprises a plurality of components defining a document related entity and a property of the entity, the token components including an operation component designating a document related operation, an address component designating the electronic address of a document or system providing a document related service, one or more parameter components, each parameter component defining a property of a document or a property of a service to be applied to a document, and a security parameter dependent upon the identity of a user associated with a document or with a document related service. The tokens are distributed from one person to another by transmission of IR data packets, and 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) satisfying 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.

Token-based document transactions

A system is presented for transmitting document references or tokens to users of integrated wireless and wire-based communication services. The system includes workstations, files servers, printers and other devices coupled to a wire-based network. Mobile computing devices are coupled to the wire-based network through either IR (infrared) or RF (radio) transceiver gateways. Each mobile computing device appears to hold a uses personal collection of documents: the device is programmed to receive, transmit, and store document tokens. A document services request available to users of the mobile computing devices is an email-to-token service. Using this service, document tokens are emailed to recipients with an email account. The transmission protocol for performing the email-to-token service includes the step of transmitting a token-to-email service request from the mobile computing device over the wireless communication service to a token-enabled server located on the wire-based network. The token-enabled server accepts a document token and retrieves from a file server on the wire-based network a document identified by the document token. Subsequently, the token-enabled server sends the identified document in an email message to an email address specified by the user.

Mobile e-mail document transaction service

A method and a system are presented for transmitting document references or tokens to users of integrated wireless and wire-based communication services. The system includes workstations, files servers, printers and other devices coupled to a wire-based network. Mobile computing devices are coupled to the wire-based network through either IR (infrared) or RF (radio) transceiver gateways. Each mobile computing device appears to hold a user's personal collection of documents: the device is programmed to receive, transmit, and store document tokens. A document services request available to users of the portable devices is a document paging service. Using this service, a process operating on a repository of shared documents monitors for changes to specified files or file locations. Identification of changes made to documents on the repository of shared documents results in the transmission of a document token to selected users of the mobile computing devices identifying the changes. Once the document token identifying the changed document on the repository of shared documents is received, the document referenced by the document token is readily printed, displayed, or forwarded using available document services.

Mobile document paging service

A system for performing document services using mobile computing devices provides users of the system with document references that can be transmitted over integrated wireless and wire-based communication services. The system includes workstations, files servers, printers and other devices coupled to a wire-based network. Mobile computing devices are coupled to the wire-based network through either IR (infrared) or RF (radio) transceiver gateways. Each mobile computing device appears to hold a user's personal collection of documents by being programmed to receive, transmit, and store document tokens. A user interface at the mobile computing devices provide users with means for fast and easy access to document services that are proximate to where they are physically located. Through the user interface, a user queries a document device proximate to their physical location. Responsive to the query, a hierarchical list of available services is displayed at the user interface. The hierarchical list provides the user with immediate access to the queried document device, as well as links to other document devices that are ordered in a location and class specific hierarchy.

System for generating context-sensitive hierarchically ordered document service menus

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.

System and method for accessing and distributing electronic documents

An interactive desktop system for automatically adjusting pan and zoom functions to change a field of view in response to user actions relative to a feedback image projected on a source document. The interactive desktop system includes an image capture system, a display system and a processor system. The image capture system grabs an image from the source document in its field of view. The display system indicates to a user the captured image using the feedback image, which is visible to the image capture system. In response to a user adjustment of the feedback image, the processor system adjusts either the pan or zoom function of the image capture system, thus changing the field of view of the image capture system.

Interactive desktop display system for automatically adjusting pan and

A method for the recording and retrieval of information relevant to the activities of a user. The invention may be employed to provide a memory prosthesis in the form of a highly portable device which records all kinds of information about the user's life, and provides a simple and rapid means of access to that information. The device receives and stores information from external sources, or objects, or from signal generators identifying specific machines, places, or people carrying other ones of the same type of device. Events comprising encounters between objects are recorded automatically, being time-stamped and stored chronologically, and a rapid search method for such a database is disclosed. The data can either be stored in the memory of the device itself, or, for better protection against failure, in a central data repository of the system, with a fail-safe backup.
