Abstract: A method and apparatus is provided which permits mobile computers equipped with modems for cellular telephone systems to obtain various classes of data communication services, as well as voice service, including taking part in local-area networks. The LAN's may be composed of real LANs in establishments or of other mobile computers. In this way, mobile computers can take part in mainstream client-server computing and also establish ad hoc wireless LANs using the cellular telephone system.

Abstract: A conference server system, for internal use in the public switched telephone network (PSTN), links to public data communication networks (e.g. the Internet) for distributing computer displayable data between participants in voice telephone conferences. The server system includes a computer sub-system for storing data generated by the participants and distributing the data in coordination with voice presentations of respective participants. Data so stored and distributed includes computer-displayable data. Other data handled by the computer subsystem represents commands and functional requests issued by participants which pertain to the handling of computer-displayable data and voice parameters of the conference. conference participants, having separate and concurrent access to both the PSTN and the data network, receive and view computer-displayable data prepared by one of the participants in coordination with the respective voice conference. The conference server system connects to voice conference management resources of the PSTN in a manner enabling the server system to control voice parameters of a voice conference in response to data requests received from participants (e.g. requests from hearing-impaired participants for enhanced audio service), as well as enabling the conference management resources to control functions performed in respect to distribution of displayable data in response to spoken requests uttered by the participants, when the telephone system contains appropriate speech recognition equipment.

Abstract: An apparatus and method in a tablet computer for disambiguating a handwriting input stream generated by a stylus-based user interface. A tablet application program interface (TAPI) of the present invention receives stroke data generated by a stroke made by a user on a digitizing tablet. The TAPI inserts the stroke data into a database. If the stroke is an editing gesture, the TAPI routes the stroke to a gesture recognizer which identifies an editing dialog. The TAPI then executes the dialog to perform operations on the database. If the application program is expecting text input, the TAPI continues to receive stroke data until it detects a closure event. The TAPI then forms a stroke group entry in the database by grouping all non-gesture stroke data received since the last closure event. The TAPI routes the stroke group data to a character recognizer, which returns candidate characters. The TAPI inserts the candidate characters into the stroke group entry. The TAPI notifies the application program each time it updates the database.

Abstract: Method and apparatus for coordinating a usage of a wireless transmission medium amongst a plurality of transmission units (12). The transmission medium is of a type that is utilized in accordance with a protocol having a transmission period that is comprised of a plurality of consecutively occurring transmission sub-periods. A method includes the following steps. A data structure (28a) is periodically circulated amongst the transmission units, the data structure being expressive of an identification of each of the transmission units and also expressive of an identification of an assigned transmission sub-period or sub-periods, if any, during which each of the transmission units is permitted to transmit on the wireless medium. The step of circulating includes the following steps: (a) receiving the data structure from a first transmission unit with a second transmission unit; (b) responsive to the receipt of the data structure at the second transmission unit processing the data structure in accordance with an amount, if any, of impending transmission activity to modify the assignments of sub-periods therein; and (c) transmitting the modified data structure to another one of the transmission units. A method of synchronizing the plurality of transmission units to a slotted transmission protocol is also disclosed.

Abstract: Methods and apparatus for operating an optical communications system having at least two communicating entities (10,12). In accordance with a method of the invention a first step transmits communication link control information from a first entity to a second entity over a first optical channel having a first data bit rate. Responsive to the transmitted communication link control information, a second step of the method transmits data information from the second entity to the first entity over a second optical channel having a second data bit rate that is greater than the first data bit rate. The first optical channel is preferably a relatively low-bandwidth diffuse transmission infrared radiation channel. The second optical channel is preferably a relatively high-bandwidth infrared channel. One of the entities is a network adapter coupled to a wired network. The network adapter is preferably ceiling mounted. The other entity may be a mobile data processor. A plurality of mobile data processors may be served by one network adapter.

Abstract: THIS INVENTION ALLOWS CUSTOMERS AND OTHER USERS OF THE PUBLIC SWITCHED TELEPHONE NETWORK (PSTN) TO ENABLE, DISABLE OR MODIFY SPECIAL SERVICES PROVIDED BY THE NETWORK (32). THE PSTN IS DEFINED HERE AS ALL EQUIPMENT WORLD WIDE (LAND-BASED, RADIO OR OTHER) ENABLING ORDINARY TELEPHONE USERS TO CONNECT TO OTHER TELEPHONE USERS, BUT EXCLUDES PRIVATE TELEPHONE NETWORKS SUCH AS "TIE LINE" SYSTEMS MAINTAINED OR LEASED BY PRIVATE ENTERPRISES. PRESENTLY CONTEMPLATED ACTIONS CAN BE TAKEN INDEPENDENT OF THE STATE OF THE CUSTOMER''S TELEPHONE (40) LINE (E.G. ON-HOOK OR OFF-HOOK), AND USUALLY USE OF EQUIPMENT OTHER THAN TELEPHONES AND COMMUNICATION NETWORKS (32) OTHER THAN THE PSTN (E.G. COMPUTERS OPERATING THROUGH THE INTERNET PAGERS OPERATING THROUGH PAGER NETWORKS). THE SPECIAL SERVICES INCLUDES EXISTING SERVICES (CALL WAITING, CALL BLOCKING, CALL FORWARDING, ETC.) AND NEW ONES (E.G. TRANSFERRING AN ACTIVE CALL FROM A DESK PHONE TO A MOBILE CELLULAR ONE WITHOUT INTERRUPTING THE CALL). SECURITY FIREWALLS, BETWEEN THE PUBLIC AND TELEPHONY APPLICATION INTELLIGENCE (TAI) SYSTEMS THAT ADMINISTER CUSTOMER SERVICES WITHIN THE PSTN, ENSURE THAT ACTIONS BY UNAUTHORIZED INDIVIDUALS DO NOT INTERFERE WITH OR ADVERSELY AFFECT TELEPHONE SYSTEM OPERATIONS. AUTHORIZED CUSTOMERS TAKING PRESENTLY CONTEMPLATED ACTIONS WILL NOT BE ABLE TO ADVERSELY AFFECT TELEPHONE SYSTEM OPERATIONS. THE PRESENT SYSTEM WILL WORK ON INFORMATION MAINTAINED AT ANY LEVEL OF AN INTELLIGENT NETWORK HIERARCHY WITHIN THE PSTN, INCLUDING SERVICE NODES THROUGH WHICH CUSTOMER SERVICES ARE TRADITIONALLY PROVIDED.(FIG. 8)
