    摘要： An electric motor drive controller for an electric vehicle driven by a motor with permanent excitation and powered by an energy source comprises: a power control stage coupleable to the motor for generating a drive signal at a voltage to control the motor at a desired speed; a voltage control circuit connectable between the energy source and the power control stage for controlling the voltage of the drive signal at a first voltage potential in one operating mode and at a voltage potential greater than the first voltage potential in another operating mode; and a mode controller for controlling the operating modes of the voltage control circuit based on properties of the drive signal.

    摘要： A scooter has at least two drive wheels which are placed in alignment with or forward a location on the scooter defined by the approximate location of the head and shoulders of a user of the scooter. The scooter may optionally have a plurality of pivot arms and pivot arm casters extending rearward of the scooter's frame for facilitating rearward stability of the scooter. The scooter may be powered by one or more motors coupled to one or more of the wheels. The scooter may also be easily dissembled by detaching the front portion of the scooter from the rear portion of the scooter.

    摘要： A system and method of providing bi-level CPAP therapy is provided that incorporates an infrared carbon-dioxide sensor to determine whether a patient is inhaling or exhaling. Patient exhalation causes the infrared light to be absorbed, while patient inhalation reduces the presence of carbon-dioxide causes little or no absorption of carbon-dioxide The level of carbon-dioxide in an associated patient breathing interface is monitored for thresholds that trigger higher CPAP pressure upon inhalation and lower CPAP pressure upon exhalation.
