Abstract: A vehicle drive system uses multi-fuel engines to provide mechanical energy as an electric generator. The electric generator provides electrical energy to an electric motor which in turn provides mechanical energy to the drive train of a vehicle. The electric generator also provides electric energy to storage batteries. Electrical energy may be provided from the storage batteries to the electric motor as needed.

Abstract: A communications system including an automated dependant surveillance-broadcast system and a global positioning system integrated into a single unit. A radio frequency receiver receives analog automated dependent surveillance-broadcast information at a selected transmission frequency and converts that information into digital form. A global positioning system receiver receives global positioning information including timing information. A processing subsystem decodes the digitized automated dependent surveillance-broadcast information in response to the timing information received by the global positioning system receiver.

Abstract: A system for removing contaminant from sulfur to a level that allows re-processed sulfur to reenter a supply chain. The system melts contaminated sulfur, filters the molten sulfur, and then dispenses the less contaminated sulfur after filtering it. More specifically, solid contaminated sulfur enters a settling tank, while heated molten sulfur circulates through the system and the settling tank. The circulation of the molten sulfur assists in the melting process of the solid sulfur, allowing the solid sulfur to melt efficiently. In preferred embodiments of the system, the system uses steam jacked sulfur lines and steam tracing to maintain temperatures for melting the solid sulfur and maintaining the molten state of the sulfur circulating through the system. Furthermore, the system comprises a programmable logic controller, which controls motors, pumps, valves, and environment monitoring instruments.

Abstract: The piping component is comprised in part of a metal housing that is positionable with a metal pipe. The metal housing forms an opening in which a piping component body is inserted. The body of the piping component can be fastened to the metal housing using an epoxy adhesive, a set screw connection, a threaded connection, press fit connection, a key connection or a pin connection or a combination of these connections. The body is comprised of plastic, which is less expensive than metal and facilitates forming, including machining or molding, while maintaining its structural integrity in a hostile fluid environment, such as in oil or gas. Piping components such as flowmeters, flow conditioners, small volume provers, static mixers, samplers, and valves are contemplated for use with these multiple materials.

Abstract: A relief device for a high-pressure gas container, comprising a main body having a generally uniform outer circumference and that defines a primary bore, the primary bore in fluid communication with an interior volume of the high-pressure gas container, the main body having a secondary bore, the secondary bore located within the outer circumference and in fluid communication with the primary bore, a spud assembly seated in the secondary bore, the spud assembly including a rupture disc that relieves to the atmosphere the contents of the container when the container reaches a certain pressure, the rupture disc located within the secondary bore and within the outer circumference, the spud assembly and rupture disc fixedly attached.

Abstract: The present invention additionally comprises a method and apparatus for generating and mixing signals for frequency-domain lifetime and spectral fluorometry. The present invention comprises a plurality of signal generators that generate a plurality of signals where the signal generators modulate the amplitude and/or the frequency of the signals. The present invention uses one of these signals to drive an excitation signal that the present invention then directs and transmits at a target mixture, which absorbs the energy from the excitation signal. The property of fluorescence causes the target mixture to emit an emitted signal that the present invention detects with a signal detector. The present invention uses a plurality of mixers to produce a processor reference signal and a data signal. The present invention then uses a processor to compare the processor reference signal with the data signal by analyzing the differences in the phase and the differences in the amplitude between the two signals.

Abstract: A method and apparatus for analyzing brain waves wherein the brain wave of interest is sampled, parameters that describe the brain wave are determined, and the parameters so determined are compared with standard parameters.
