  • Publication number: 20120087793
    Abstract: A Multi Purpose Variable Speed Wind Powered Generator is configured to generate electrical power to all types of transportation and equipment in any wind condition. An on board trip computer monitors wind speed and calibrates settings. As wind speed increases in certain increments the wind speed activates the variable pitch modulation, which controls the blades angle of attack controlling rotor rpm. As the wind speed increases substantially wind speed activates the variable pitch modulation in the rotors decreasing pitch to keep rpm relative. At extreme wind speeds rotor pitch modulation adjusts almost to a neutral position to keep rotor rpm relative. Then the onboard trip computer responds in like sequence in union with wind monitor and rotors partially closing the grill diaphragm disk. This allows less airflow through the grill diaphragm disk to the rotors. Rotor modulation returns back to original pitch positioning and the processes are repeated as needed through every wind speed.

  • Publication number: 20110101688
    Abstract: A Multi Purpose Variable Speed Wind Powered Generator is configured to generate electrical power to all types of transportation and equipment in any wind condition. The wind speed monitor gives the variable pitch rotor the precise angle of attack to keep rotor RPM relative and stable at all wind speeds. A wind diverter keeps wind flowing through rotors with out wind back up or bottleneck. An onboard trip computer responds in like sequence in union with the wind monitor and rotors through out each trip. The onboard trip computer is designed to maintain rotor RPM as if the transpiration was moving from 10 to 40 miles per hour. The pitch changes as the wind speed changes keeping the rotor RPM relative. Rotor brakes are to slow or stop rotors movement at any time for any reason.

  • Patent number: 7901336
    Abstract: The present invention is for the rehabilitation of stroke, brain or nerve damaged patients whose feet are paralyzed or unresponsive and must relearn lower leg and foot muscle control. A foot box can support a patient's foot with the foot box mounted above a flat base plate for movement by the patient. The foot box can be pivotally mounted by a swivel bearing to a shaft on the base plate with a forward end of the foot box supported by a wheel. A hemisphere support on the lower surface of the foot box permits movable support of the foot box when the swivel bearing is disengaged from the shaft and the wheel is raised. Attachments for the ends of handled pull cords are provided on the front corners and sides of the foot box. Pulleys on the base plate guide the pull cords.

  • Publication number: 20100228164
    Abstract: The present invention is for the rehabilitation of stroke, brain or nerve damaged patients. Due to a stroke, brain injury or nerve damage a patients feet become paralyzed and unresponsive. The patient must relearn lower leg and foot muscle control. The patient must use their own will, as well as, some force from the pull cords to stimulate, manipulate and reprogram motor skills. Parts A, B, C of the embodiment provide rehabilitative stimulation to the muscles in the lower legs and feet at all angles of deflection. The stroke master rehabilitative invention is designed to help the patients regain mobility by stimulating damaged nerves and muscles through repetition and the sheer will of the patient.
