  • Publication number: 20220176829
    Abstract: Embodiments of the present invention provide a method and system for controlling an electric vehicle's electric motor output. The method obtains electric vehicle data, user-related data, and receives input from at least one sensor. A controller is utilized to evaluate the electric vehicle data, the user-related data, and the input from the at least one sensor, and automatically tailor an output power curve of an electronic motor to obtain a best performance for the electric vehicle for a given rate of conservation of a battery power.

  • Patent number: 7463931
    Abstract: Electrobiological stimulation is carried out transcranially by applying high frequency squarewave bursts exhibiting no d.c. term across the cranial region. Such stimulation is commenced employing ramp generators and positive and negative voltage converters which evolve the requisite baseform and burst frequencies having a voltage waveform which is square in nature. Both voltage and current are sensed and subjected to comparator logic in conjunction with predetermined thresholds and windows. Overcurrent detection and overvoltage detection is provided in hard wired fashion to assure rapid shutdown response. D.C offset detection is provided along with waveform balance tests to further assure the safety of the system. Diagnostic procedures as well as therapeutic procedures may be carried out with a system version which provides for the application of a stimulus in conjunction with safety monitoring and controller based development of stimulating waveforms, all of which exhibits no d.c. term.
