Abstract: A structured document system for generating, from a single set of parts of speech entered into a computer, alternative forms of documents with different formats and syntaxes using the same set of parts of speech. For each set of parts of speech, a record is created which includes alternative forms of the verb, alternative forms of any product contained in the sentence, and a statement of the requirement level as mandatory, recommended, or optional. A document is defined by specifying step levels and, for each step level, a set of parts of speech. For each alternative document to be produced, a complete syntax is specified which includes a concatenation rule for each step level. When the document is generated according to the specified syntax, concatenation rules determine the format and structure of each heading or action step.

Abstract: Talking video games can provide simulated voice dialog between human players and animated characters on a TV screen. Two or more players can take turns responding to animated characters and two or more animated characters can respond to each player and to each other, thereby providing three-way or four-way conversations. Pictures and voices are generated from digital data separately stored on a laser-readable disk such as a CD-ROM in compressed form. As the game is played each animated character talks to the human game players and waits for a response. Each player has a hand-held controller that displays two or more phrases or sentences and a player responds by pressing a button next to a selected phrase. An animated character then responds to the selected phrase as if it had been spoken by the human player. Speech recognition is not required. Each scene branches to two or more subsequent scenes.

Abstract: An infant walking aide device which helps an adult to assist a small child or toddler in learning to walk. A fully adjustable harness is supported by a crossbar which is held by the adult. The harness has straps which fit over the child's shoulders, under the child's crotch, around the child's waist, and across the child's upper back. The crossbar and suspending straps clip to the harness for easy attachment and release. The suspending straps are adjustable in length to accommodate various carrying configurations. The crossbar is width adjustable and may be grasped by either one or two adults. In addition, the crossbar is curved so that it can be placed over an adult's head and supported by the adult's neck and shoulders. Finally, a safety strap or tether attaches between the harness and the adult for use as either a leash or a safety tether providing added security.

Abstract: A method and apparatus for determining integrated circuit layouts of a random access memory (RAM) from a virtual circuit description and specification of a process technology. Starting with high-level descriptions of a circuit, a virtual geometric description of the circuit is developed in terms of reference points relative to a substrate surface. When the process technology is specified, the relationships among the reference points is determined, as in the layout of the RAM. These relationships account for variable sizing of circuit features and pitch matching of circuit features. A connectivity model and a simulation model of the RAM are also produced by the method and apparatus. These model can be used to verify that the RAM is connected as desired and has the desired performance.

Abstract: A graphical user interface for a computer system that includes a memory for storing application programs and application files. The user interface permits the user to initiate execution of a selected application program, and produces a snapshot that graphically represents a screen produced during the execution of the application program. The snapshot may be displayed after execution of the application program is terminated, and provides a visual reference for the application file that was opened when the snapshot was taken. Snapshots and their corresponding application files may be organized in a project format, and new documents opened by an application program may be automatically placed in the opened project. An improved technique for initiating the execution of application programs is also described.

Abstract: Longitudinally extensible and shortenable pump poles designed for hand and arm action in dual-action exercise apparatus such as cross country ski exercises and dual-action climbers, treadmills and the like, such pump poles being fixedly attached to the apparatus base rearwardly thereof and manipulated concurrently with or independently of reciprocating leg action. Each pump pole has inner and outer telescoping tubes and an air pressurizable chamber providing greater resistance to pole shortening movement than occurs during pole lengthening movement. Hand and arm movement by the user when reciprocating the pole handles simulates the hand and arm movement of a person actually moving over ground.

Abstract: A composition for vibration damping of a structure releasing vibrational energy through its surface is disclosed. The composition includes either a substantially non-homogeneous visco elastic damping layer on the surface of the structure, or a visco elastic damping layer that is either homogeneous or non-homogeneous discontinuously attached to the surface of the structure. The non-homogeneity of the damping layer is caused by substantially planar voids, substantially spherical voids, or particles. The discontinuous attachment of the damping layer and the surface of the structure is caused by a plurality of grooves, indentations, or by the presence of a non-adhesive material where the damping layer and the surface structure are not secured.

Abstract: A method and apparatus for providing spread spectrum communications. The apparatus starts with designated spread spectrum communications parameters, such as default transmitted power level, pseudo-noise (PN) sequence, PN sequence length, and frequency channel, having values which are chosen to ensure that spread spectrum communications can be carried out between a first station and a second station. The apparatus of the invention then changes the values of the spread spectrum communications parameters to the minimum values necessary to provide a given level of communications reliability. If the conditions facing the spread spectrum communication system change so that communications reliability falls below the given level, the apparatus resets the values of the spread spectrum communications parameters to the default levels and begins again to change their values to provide the given level of communications reliability.
