Abstract: A footwear system for monitoring weight, posture allocation, physical activity classification, and energy expenditure calculation includes an accelerometer configured to obtain acceleration data indicative of movement of a user's foot or leg. The footwear system may also include a pressure sensing device mounted in an insole and configured to obtain pressure data indicative of pressure applied by a user's foot to the insole, as well as a transmitter communicatively coupled to both the accelerometer and the pressure sensing device and configured to transmit the acceleration and pressure data to a first processing device configured process the acceleration data and the pressure data to distinguish a first posture from a second posture different from the first posture and process the acceleration data and the pressure data to distinguish a first movement-based activity from a second movement-based activity different from the first movement-based activity.

Abstract: A wind turbine system and a method for controlling a rotational speed of a rotor of such wind turbine system are provided. The system included a wind turbine having a rotor having airfoils having an orientation relative to wind and a rotational axis. The system further includes a structure supporting the wind turbine above ground. The support structure is coupled to the ground. The structure has first portion closer to the wind turbine and a second portion farther from the wind turbine. The first portion will move farther in response to the wind acting across the structure than said second portion causing the turbine rotational axis to tilt. The method includes tilting the rotor rotational axis about an angle, and varying the angle in response to changes of the wind force.

Abstract: A method is provided for controlling the sagging of a power transmission cable hang between two towers. The cable has a first supporting portion and a second conductive portion. The method includes a first act of mounting the cable between the two towers, such that when mounted between the towers the cable has a cable load. The method further includes a second act of stretching the first portion to have a cable sag less than a desired sag, a third act of releasing at least some of the tension to obtain the desired sag, and a fourth act calculating a load magnitude carried by the first portion. If the load magnitude is less than a desired load magnitude the method includes repeating the second, third and fourth acts until the load magnitude is at the desired level.

Abstract: Control system for devices such as an audio reproduction system, an actuator device, an electromechanical device and a telephony device. The system includes control circuitry that receives an input signal and a signal indicative of a position of a portion of the controlled apparatus. The control circuit provides an output signal to the controlled apparatus to affect an operation of the controlled apparatus. The output signal provides control of the apparatus to compensate for one or more of: motor factor; spring factor; back electromotive force; and impedance of a coil in a driver of the controlled apparatus. The signal indicative of position is derived by one or more position indicator techniques such as an infrared LED and PIN diode combination, position dependent capacitance of one portion of the controlled apparatus with respect to another portion of the controlled apparatus, and impedance of a coil in the controlled apparatus.
