Abstract: A method is provided for operation of a wind turbine having rotor blades attached to a hub, wherein a controller compensates for torsionally induced blade twist. The method includes operating the wind turbine according to a rated power output curve and maximum design thrust value, and periodically or continuously detecting for induced torsional twist in the rotor blades. Upon determination of torsional twist being induced in the rotor blades, the method includes adjusting the maximum thrust value in the control program to compensate for the induced twist. The wind turbine controller then controls pitch of the rotor blades as a function of the increased maximum thrust value so that power output of the wind turbine is not unnecessarily limited or increased by the induced twist on the rotor blades.

Abstract: A system and related devices for continuous and real-time monitoring and detection of head impact and corresponding trauma. The system may include a passive sensor mounted to a subject's tooth using dental hardware or adhesive so as to harness the firm coupling between the subject's tooth and cranium. With such firm coupling established, the impact data measured by the tooth-mounted sensor can be manipulated, through the use of a transfer function, by external processors to determine and communicate the impact experienced by the subject's head. The system is configured for use with an external power source whereby the passive tooth-mounted sensor is activated by means of a wireless transfer circuit such as an inductive power transfer circuit or an ultrasound power transfer circuit. The wireless activation of the powerless interior sensor system provides compatibility with multiple external power configurations, thereby enabling efficacious and continuous monitoring of the subject.

Abstract: To make secondary anchoring of small boats quick, safe, versatile, a low cost buoyant apparatus with an attached tripping strap has been invented to permit transport of a secondary anchor to its holding location. The invention, in addition serves to prevent excessive boat swings once anchored in restricted anchorage, and can also serve as a marker in the event that an earlier anchored boat needs to move and return to the same spot. This buoyant apparatus is very versatile; it can be used from the boat's bow, from the stern, and also as a lunch hook. Although the buoyant ring has an appearance of a life preserver, it is not intended for that use, and does not qualify as U.S. Coast Guard or Sheriff Regulation safety equipment.
