Abstract: Methods and systems are described herein which allow to determine an icing condition without requiring a wind speed measurement. The methods and systems use two sensing members both being exposed to conditions in an environment. The determination is made based on a capacity of the sensing members to react differently to the conditions to which they are exposed. The conditions can be environmental or controlled. The determination includes measuring a variable indicative of the thermal state of each individual sensing member, and processing the measured values to generate the signal indicative of icing condition. The icing condition can be instrumental or meteorological.

Abstract: The method includes receiving a value of a quantity of heat applied to at least a portion of a structure, said structure having a sensor surface exposed to the environment, receiving a temperature measurement of the sensor surface, receiving a wind speed measurement of the environment, receiving an ambient temperature measurement of the environment, determining a heat transfer projection of the sensor area using at least the wind speed measurement, the ambient temperature measurement, and one of the value of a quantity of heat and a target temperature of the sensor surface; comparing the heat transfer projection to an associated heat transfer value, and generating a signal indicating the icing condition status based on the comparison.

Abstract: An energy harvesting system for footwear is described having a sole, heel and an upper and comprising a first gaseous bellows pump formed at the sole of the footwear with the bellows hinged forward of the sole; a second gaseous bellows pump formed at the heel of the footwear with the bellows hinged forward of the heel. A gas reservoir is mounted to the upper of the footwear in fluid communication with first and second gaseous pumps downstream of the pumps and adapted to receive the gaseous medium exiting under pressure from the pumps. An axial turbine has an output shaft mounted on the footwear upper downstream of the reservoir and adapted to receive pressurized gas from the reservoir when a predetermined pressure threshold is attained in the reservoir so as to activate the axial turbine; and an electrical generator mounted on the upper, downstream of the axial turbine and engaged with the turbine output shaft which can be engaged only when a predetermined shaft velocity threshold has been attained.

Abstract: System and method for converting kinetic energy from a fluid flow into mechanical energy, the method comprising the steps of: a) providing a turbine including first and second hydrofoils, each of the hydrofoils being able to move lin-early in a heaving motion, and being able to oscillate about a spanwise axis in a pitching motion, said heaving and pitching motions being quasi-si-nusoidal, b) coupling the heaving motions of the first and second hydrofoils to the pitching motions of the second and first hydrofoils respectively, with the pitch-heave motion phase being substantially equal to the inter-hydrofoil phase, the heaving motion of one of the hydrofoils thereby driving the pitching motion of the other hydrofoil; and c) transforming the heaving motions of the hydrofoils into a rotational movement of a rotatable shaft, with linear-to-rotary transmission means.

Abstract: A a system for relocating a workload partition (WPAR) from a departure logical partition (LPAR) to an arrival LPAR determines an amount of a resource allocated to the relocating WPAR on the departure LPAR and allocates to the relocating WPAR on the arrival LPAR an amount of the resource substantially equal to the amount of the resource allocated to the relocating WPAR on the departure LPAR.
