IPC: A63B69/00
Filed: 2000-07-04
Abstract: A method for creating a customized visual presentation of a physical therapy routine includes an initial step of evaluating the capability of the individual for performing the routine. Once the evaluation is complete, the individual is categorized according to the evaluated performance capability.   Based on the category of the individual, the physical therapist identifies a sequence of physical exercises for the individual which defines the individualized physical therapy routine. The therapist then accesses an archives which includes a plurality of digital excerpts that each demonstrate the performance of a particular physical exercise. The physical therapist selectively retrieves digital excerpts from the archives which visually demonstrate the physical exercises that will make up the routine. These digital excerpts are edited appropriately and compiled into a videocassette tape and provided to the individual.

Title: Telecommunications switch with multiple ports for host-node communications
Inventor: GHAI RAJAT
IPC: H04Q3/00
Filed: 1999-01-28
Abstract: The system includes switching nodes with multiple ports for node-host communication, each port thereby connects the switching nodes to one or more hosts. One of the ports in a switching node is designated as a primary or master port and it connects the switching node to a default host. The default host controls all ports in the switching node and because applications on the default port are given the highest priority during switching node processing, the default host is useful for applications that require instant response from the switch. The other ports in the switching node are secondary ports and they connect the switching node to one or more secondary hosts simultaneously. The applications on the secondary hosts are given a lower priority than the default host's application. Therefore, the secondary hosts are useful for applications that do not require instant response from the switching nodes.

Patent CA-2339276-A1 (CA)
Title: Anti-coking fuel injector purging device
Inventor: PROCIW LEV ALEXANDER
IPC: F02C7/232
Filed: 1999-04-19
Abstract: The invention relates to an air purge system for preventing coke buildup in gas turbine engine fuel injectors, and in particular in the relatively small orifice pressure atomizers of a primary fuel injector. The air purge system is activated on engine shutdown to continuously exhaust cooling air through the injector orifices for an extended purge period after shutdown, for example 1-1.5 hours. A battery operated air blower connected to the fuel line forces cooling air through the injector until a thermocouple switch deactivates the blower on sensing an injector temperature below 150 °F. At this low temperature, coke formation does not occur and during engine operation efficient combustion minimizes coke formation.

Title: Production and use of a premium fuel grade petroleum coke
Inventor: ETTER ROGER
IPC: C10B55/00
Filed: 1999-08-20
Abstract: A premium "fuel-grade" petroleum coke is produced by modifying petroleum coking technology. Coking process parameters are controlled to consistently produce petroleum coke within a predetermined range for volatile combustible material (VCM) content. The invention includes a process of producing a coke fuel, the method comprising steps: (a) obtaining a coke precursor material derived from crude oil and having a volatile organic component; and (b) subjecting the coke precursor material to a thermal cracking process for sufficient time and at sufficient temperature and under sufficient pressure so as to produce a coke product having volatile combustible materials (VCMs) present in an amount in the range of from about 13 % to about 50 % by weight. Most preferably, the volatile combustible materials in the coke product typically may be in the range of from about 15 % to about 30 % by weight. The present invention also provides methods for (1) altering the coke crystalline structure, (2) improving the quality of the coke VCM, and (3) reducing the concentration of coke contaminants. Fuels made from the inventive coke product and methods of producing energy through the combustion of such fuels are also included.  Finally, novel environmental control techniques are developed to take optimal advantage of the unique characteristics of this upgraded petroleum coke.

Title: Safer more x-ray transparent spinal implant
Inventor: LAWSON KEVIN JON
IPC: A61B17/88
Filed: 1999-10-28
Abstract: A spine-stabilization implant (30) comprises a one-piece bullet shaped shell with bone tapping screw threads (32) on its outside surface. the screw threads are longitudinally interrupted by several end to end flutes (34) distributed in parallel around the circumference. Bone growth access windows are (36) provided at several locations through the flutes. Such construction gives the spine stabilization implant a hexagonal cross section with a hollow central core (38). A drive tool can be slipped into the back end. After spreading two adjacent vertebrae as much as the interconnecting tissues will allow, a bore is made by a surgeon during an operation into the intervertebral space of a patient's spine, e.g., deep into, the disc. The drive tool is then used to push the spine stabilization implant down the bore, and into the intervertebral space. The tool is then twisted such that the bone tapping screw threads cut into, and lock onto the opposite surfaces of the adjacent vertebrae. The tool is then withdrawn. Morsel bone is packed into the spine stabilization implant to promote new bone growth that will fuse together the opposite surfaces of the adjacent vertebrae.
