Title: Utilization of energy from flowing fluids
Inventor: BRETT JAMES FORD
IPC: G01V11/00
Filed: 2001-07-26
Abstract: A fluid powered downhole vibration tool is used in a well bore 12 where fluids are pumped from the surface into a formation through the well bore. The tool includes a fluid powered motor located within the well bore. The fluid powered motor is in communication with the fluids pumped from the surface. In one embodiment, an actuator coupling is rotated by the fluid powered motor. A seismic mass 16 is rotated in the well bore by the actuator coupler, the seismic mass engaging the well bore and causing vibration of the well bore. Alternatively, the fluid may be obtained from the formation and flow up the wellbore 12. The motor is then powered by the upward flow. The motor may be a turbine that is used to generate electricity which is used to drive a seismic vibrator. The motor may be positioned with a packer that has a by pass valve therein. The tool can be used to promote fluid flow from the formation to produce seismic vibrations or during cementing or gravel packing.

Title: Prosodic boundary markup mechanism
Inventor: PHELAN PETER
IPC: G10L13/10
Filed: 2001-08-14
Abstract: An automated prosodic boundary markup mechanism is implemented in a text-to-speech converter system. The mechanism parses text at 116 and assigns prosodic boundaries to the text at 118 based on the parse. However, this results in overmarking of prosodic boundaries. Prosodic boundary constraints are applied to the marked up text based on the parts of speech assigned at 114 to the words in the text portion to remove inappropriate boundaries. For example, a prosodic boundary is removed if it immediately follows a deaccented word, if there is only one word between the boundary and punctuation, if the boundary lies between two words of the same syntactic class, or if the boundary immediately follows a function word.

Either shaft or driving member may be twisted. The faces of the polygonal portion may be straight, concave or convex in cross-section and the twist angle is 0{ 10' to 1{. Also disclosed is a method of manufacturing a pinion including forging, rough machining, hobbing a gear, heat-treating and hard turning journals and a polygonal length on a shaft without grinding.

Title: A communication system that provides extra protection when transmitting critical data
Inventor: GIPSON JACK ANTHONY
IPC: H04W16/12
Filed: 2001-12-19
Abstract: A method and a communication unit for communicating data based on frequency reuse by a plurality of transmitters (10, 20, 30). The transmitters (10, 20, 30) are coupled to a controller (40) that schedules communications of data during the repetitive time slots. Different frequency reuse patterns are used when scheduling critical and non-critical data transmissions. A first reuse pattern is used for scheduling the transmission of critical data, and a second reuse pattern is used for scheduling non-critical data. The invention can be applied to any inbound or outbound time slotted protocol that have message fragments spanning over one or more time slots. The reuse pattern can be varied slot by slot, o use a less aggressive reuse for communicating critical data and a more aggressive reuse for communicating non-critically data. As a result, data can be communicated more reliably a d throughput can be increased by protecting critical data transmissions via a less aggressive reuse.
