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 conventional LANS in establishments or of other mobile computers. In this way, mobile computers can take part in mainstream client-server computing and also establish wireless LANs using the cellular telephone system.

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.

Abstract: A wide band radio frequency measurement probe assembly is described for use in connection with circuits constructed of microstrip circuitry. The probe includes a resistive voltage divider connected to a microstrip transmission line enclosed in a hand held housing. Ground points for engagement with ground contacts on the probe are provided on the circuit board substrate and are plated through to a ground plane on the other side of the substrate.

Abstract: This invention provides a method for repair for poles which have been damaged which is easily transportable, simple to install, and easily adaptable to many classes of poles. The method involves excavating around the pole, cleaning the surface of the pole, pumping a fumigant into the pole, cutting back to solid wood, installing a high compressive strength filler, applying a bonding agent to the clean surface, and then applying strips of a composite fiberglass mat and resin to the pole in a controlled manner until a desired encasement thickness has been achieved. The repair is completed by application of an ultraviolet resistance coating to the pole.

Abstract: A bicycle handlebar stem is made of two separate parts, a tubular shank and a gooseneck. This eliminates or substantially reduces long drilling operation for the stem and it simplifies the forging of the gooseneck. The gooseneck is shaped for forging thereof in a manner such that the meeting of the forging dies does not occur across the top of the stem, and the forging operation can forge identifying insignia on the stem top and/or form a recess of receiving an identification plate. Destruction of the indicia on the plate in the case of a stolen bicycle is easily detected. In order to inhibit commerce in such stolen bicycles the handlebar stem is mounted in the steering column in a manner that requires a special tool to remove it and to replace it by another.
