Abstract: A pen-based processor needs to be usable to input and edit script like a text-based computer but retain a resemblance to the user of a pad and pencil. The disclosed system and method implement input, editing and other manipulation of glyphs including handwritten script, ASCII test, bit-mapped images and drawings in a common document, using a compatible internal representation of the data and a simple, consistent set of user control functions. These functions are invoked using an intuitive and interactive set of user gestures which do not distract the user from the task of inputting or editing the document. A two-step gesture method avoids confusion between strokes and command gestures and allows use of similar gestures for different functions within the same and different contexts. The system infers from customary user writing conventions that certain relationships of data are to be preserved and maintains the relationships, subject to user override, during editing.

Abstract: An apparatus and method for dispensing water in a radially uniform distribution over a surface. The reciprocating sprinkler device includes a housing, an inlet port for receiving water under pressure to the housing, at least two outlet ports capable of dispersing water in differing directions, and a reciprocating water driven valve. Each outlet port includes an opening for receiving water from within the housing. The reciprocating valve alternately covers portions of the outlet port openings as it moves, thereby modulating the flow of water between the outlet ports resulting in increasing and decreasing flows of water across a surface.

Abstract: A smart hypermedia system that acquires user characteristics either directly or inferentially. Simple associative networks serve to model user profiles, including relationships between user goals and the hypermedia information nodes. Hypermedia links to other nodes are recommended by ranking a link list in an order that depends on one or more user profiles containing information relating to users' goals and interests. Users can teach the system directly by rearranging the order of suggested links on the list. The system can also learn indirectly by observing how long and in what sequence the user views each hypermedia information node. User profiles can be combined to form group profiles and may be dynamically and continuously updated to form an adaptive system profile. The two system learning modes may be simultaneous or disjoint.

Abstract: A pen-based processor needs to be usable to input and edit script in the manner of a text-based computer but retain a resemblance to the user much like a pad and pencil. The pen-based computer implements enable input, editing and other manipulation of handwritten script, ASCII text and drawings in a common document using a compatible internal representation of the data and a simple, consistent set of user control functions. These functions are invoked by the user with an intuitive and interactive set of user gestures which do not distract the user from the task of inputting or editing the document. A two-step gesture method avoids confusion between strokes and command gestures and allows similar gestures to be used for different functions within the same and different contexts. The system infers from customary user writing conventions that certain relationships of data are to be preserved and maintains the relationships, subject to user override, during editing.

Abstract: A daisy wheel printer with a low mass carriage is driven by a pair of bidirectional stepping motors mounted on the printer frame. The carriage and print wheel are each driven by their respective motor through a belt and pulley drive extending side to side of the printer frame. The motors and pulleys are proportioned so that a step of either stepping motor rotates the print wheel from one character position to the next, thereby synchronizing print wheel rotation with carriage movement. The motors are driven independently, under control of a microcomputer in the printer, to vary the phase of rotation of the print wheel relative to movement of the carriage. Stops at one end of the printer frame are used to physically position the carriage and wheel to known initial locations.
