摘要： 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.

摘要： In response to a data processor (10) breaking a wireless link with a first, original, link adapter (12) a first step deletes the data processor from an active group of the first link adapter and re-directs network datagrams intended for the data processor to a spooler. In response to the data processor subsequently establishing a link with a second, new, link adapter a next step adds the data processor to the active group associated with the second link adapter and transmits stored datagrams in a First In/First Out order from the spooler to the second link adapter for transmission to the data processor. In response to the storage device transmitting all of the stored datagrams to the second link adapter the method includes the further steps of terminating the re-direction of datagrams from the first link adapter to the storage device and, receiving, from the network with the second link adapter, further datagrams addressed to the data processor.

摘要： 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.
