Abstract: A sincerity index system is provided for determining the sincerity of a person undergoing muscular testing. The system includes a muscular force detector for sensing and measuring the force exerted by first muscles upon a predetermined body movement and providing a first signal proportional to the force exerted. An electromyograph senses and measures the bioelectric activity of second muscles corresponding to the first muscles, the electromyograph providing a second signal proportional to the bioelectric activity. An interface device processes the signals and provides at least two factors, and an index-forming program combines the factors in a predetermined manner to provide a sincerity index having upper and lower limits. Using the system one can ascertain faked or exaggerated soft tissue injury, the extent of injury, and the extent of concomitant disabilities.

Patent CA-2400077-A1 (CA)
Title: Method of producing nitrogen enriched air
Inventor: NEMSER STUART MARSHALL
IPC: B01D71/32
Filed: 2001-01-31
Abstract: A membrane separation process and apparatus involves contacting a gas feed mixture (19) with one side of a selectively gas permeable membrane (9) and allowing the components to pass through the membrane to form a permeate composition (17) in contact with the opposite side of the membrane and leave a retentate composition (15) on the feed side of the membrane. The process includes introducing a sweep flow of feed gas (24) into the permeate composition near the membrane at a rate effective to increase the enrichment of the retentate composition in the less preferentially permeable component of the feed mixture to a concentration much greater than is achieved without the sweep flow. This process improves single stage membrane separation effectiveness so that the need for conventional multistage separations to achieve moderate to high purity retentate compositions can be obviated and is particularly useful for providing enriched air in the concentration range of 80-90 vol. % nitrogen.

Abstract: An electric power generator harvesting the gravitational pull of the Earth, having a platform member, an electric generator housing slidably positioned on the platform member, the electric generator housing coupled to an axle having a rotor gear, an endless belt having tread members, a drive wheel, and an idler wheel, wherein the rotor gear is in mating contact with the tread member of the endless belt. Change of orientation of the platform member along a horizontal longitudinal axis causes the electric generator housing to slide on the platform member while the counter motion of the rotating endless belt maintains position of the electric generator housing on the platform member. As a result of rotation of the axle, electric power is generated by turbine generator located inside of the electric generator housing. Some of the generated electric power could be utilized to supply the needed power for rotation of the drive wheel rotating the endless belt. Hence, the electric power generator is capable of being self-sustaining.

Title: System identification method
Inventor: NISHIYAMA KIYOSHI
IPC: H03H21/00
Filed: 2001-10-16
Abstract: Quick real-time identification and estimation of a time-non-varying or time-varying system. A new H.infin. evaluation criterion is determined, a fast algorithm for a modified H.infin. filter based on the criterion is developed, and a quick time-varying system identifying method according to the fast H.infin. filtering algorithm is provided. By the fast H.infin. filtering algorithm, a time-varying system sharply varying can be traced with an amount of calculation O(N) per unit time step. The algorithm completely agrees with a fast Kalman filtering algorithm at the extreme of the upper limit value. If the estimate of impulse response is determined, a pseudo-echo is sequentially determined from the estimate and subtracted from the real echo to cancel the echo. Thus an echo chancellor is realized.

IPC: H04B10/12
Filed: 2001-11-14
Abstract: A system and method for receiving a communication signal includes a timing source that generates a stable timing signal and a stabilized local oscillator that receives the stable timing signal and uses the stable timing signal as an input to generate a stabilized oscillator signal. An antenna receives the communication signal at a receiving frequency, and the communication signal is filtered and amplified. A low noise block converter uses the stabilized oscillator signal to convert the receiving frequency of the communication signal to a stable lower frequency. A fiber optic transmitter converts the communication signal to an optical signal and transmits the optical signal over fiber optic cable. A fiber optic receiver receives the optical signal over the fiber optic cable. The optical signal then can be converted to an electrical signal.
