Title: Electric submersible pump with specialized geometry for pumping viscous crude oil
Inventor: JAMES MARK C
IPC: E21B43/12
Filed: 2003-02-19
Abstract: A centrifugal pump has impellers for pumping low flow, high viscous materials. The impellers have high exit angles greater than 30 degrees and preferably greater than 50 degrees. The impellers and diffusers have specific geometry that varies with viscosity. The pump has zones of impellers and diffusers with the exit angles and geometry in the zones differing from the other zones. The exit angles decrease and geometry varies in a downstream direction to account for a lower viscosity occurring due to heat being generated in the pump. One design employs small diameter impellers and high rotational speeds.

Title: Wheel mounted power generator and wheel condition sensing apparatus
Inventor: LARSON GERALD L
IPC: B60C23/00
Filed: 2001-10-04
Abstract: An electromechanical apparatus suitable for mounting on a vehicle wheel power for generating telemetry relating to the wheel including tire temperature and pressure. The apparatus includes a pendulum mounted to rotate freely relative to the vehicle wheel which is positioned from the wheel hub. When the wheel is set to rotation, the pendulum freely hangs from the wheel hub under the influence of an off center counterweight having sufficient inertia to prevent rotation of the pendulum with the wheel. The pendulum is used to position one or more magnets (38) to be used to excite field coils (24), which are mounted with respect to the wheel hub to rotate with the wheel. The magnets (38) and rotating coils cooperate to energize a power utilization circuit also mounted with respect to the wheel hub to rotate therewith. The utilization circuit (100) may include such sensors as desired, typically including though a tire pressure gauge and tire and wheel hub temperature gauges. The apparatus is readily extended to incorporate a tire pressurization pump, which may be a solenoid pump (72) powered indirectly from the rotating coils, or by a magnetic button pump (42).

Title: Optimized scalabale network switch
Inventor: GARA ALAN G
IPC: G06F12/08
Filed: 2002-02-25
Abstract: In a massively parallel computing system having a plurality of nodes configured in m multi-dimensions, each node including a computing device, a method for routing packets towards their destination nodes is provided which includes generating at least one of a 2m plurality of compact bit vectors (115, 154) containing information derived from downstream nodes. A multileve l arbitration process (116, 155) in which downstream information stored in the compact vectors, such as link status information and fullness of downstream buffers (130, 140), is used to determine a preferred direction and virtual channel for packet transmission. Preferred direction ranges are encoded and virtual channels are selected by examining the plurality of compact bit vectors (115, 154). This dynamic routing method eliminates the necessity of routing tables, thus enhancing scalability of the switch.
