    Abstract: The present invention discloses a pressure converter system for sustainably forcing saline water through a semi-permeable membrane, comprising a hydraulic oil pump, a hydraulic oil cylinder comprising pressurized oil generated from the hydraulic oil pump, a sustainable energy source for powering the hydraulic oil pump, a saline water cylinder containing saline water, wherein the hydraulic oil cylinder and the saline water cylinder are connected using a piston and an electrical circuit for determining a direction of movement of the piston. This system may be developed to a stand-alone desalination facility comprising a ducted windmill that can harvest energy from a wide range of wind speeds, especially very low wind speeds. Because of the above, the present invention successfully converts mechanical energy to high pressure that is required to produce fresh water from saline water.

    Abstract: Disclosed is an energy mixer having a first active diode coupled between a first input node and an output node, and a second active diode coupled between a second input node and the output node. A first capacitor is coupled between the first input node and a dynamic node, and a second capacitor is coupled between the second input node and a third node. Switching circuitry is configured to selectively couple the dynamic node between a fixed voltage node and the second input node in response to a control signal provided by control circuitry. When an output voltage at the output node is within a first range, the dynamic node is coupled to the fixed voltage node and when the output voltage is within a lower voltage second range, the dynamic node is coupled to the second input node such that first capacitor and second capacitor are coupled in series.

    Abstract: The location and morphology of an electrostatically manipulated flame can be controlled through the action of an electrostatic field on the flame, virtually independently of overall mixture composition and imposed strain rate. An electrostatically controlled burner can manipulate a position of a flame between an oxidizer source and a fuel source by way of one or more electrodes configured to produce an electrostatic field proximate to one of the fuel source and the oxidizer source.

    Abstract: A variable stiffness joint and method to alter the stiffness of the joint with multiple stiffness levels is described wherein a plurality of stiffness bits (m) are used for enabling 2 m stiffness level variations for the joint. Each stiffness bit comprises an elastic element in mechanical connection with a clutch (21, 22, 23). The joint revolves with zero stiffness level when all the clutches (21, 22, 23) are disengaged whereas a clutch (21, 22, 23) involves one of the elastic elements which alter the stiffness of the joint. Engaging other clutches (21, 22, 23) involve more elastic elements for altering the joint stiffness and the resultant joint stiffness is determined by adding the stiffness values of all the involved springs (6, 7, 8).

    Abstract: A method for transmitting a data block begins with segmenting the data block into a number of data sub-blocks. Each data sub-block where a number of high bits is greater than a number of low bits is then inverted. The data sub-blocks are then grouped into sets of data sub-blocks. For each set of data sub blocks, a number of pulses indicative of a number of high bits in each one of the data sub-blocks in the set is transmitted, there is a delay, and a number of pulses indicative of each high bit in each data sub-block of the set of data sub-blocks is transmitted followed by a delay. Finally, a number of pulses indicative of which ones of the data sub-blocks were inverted is transmitted.
