Abstract: Disclosed is a time-to-digital converter (TDC)-based device comprising a crossbar array for generating a current, a current-controlled delay line 104 for converting the current received from the crossbar array into a time pulse, and a TDC circuit 106 for measuring and converting the time pulse into digital output.

Abstract: A turbine (100) for generating energy is provided herein. The turbine (100) includes a hub (102), and a plurality of blades (104A, 104B, and 104C) attached to the hub (102). The turbine (100) further includes a rotor plane having disposed thereon masses (114) that are configured to be moved in a radial direction by a driving mechanism. The turbine (100) further includes an energy storage means connected to the driving mechanism. During operation, the blades are configured to be rotatable by a moving wind, and the driving mechanism is configured to move the masses (114) radially inwards or outwards in the rotor plane.

Abstract: Exemplary methods of etching a silicon-containing material may include flowing a fluorine-containing precursor into a remote plasma region of a semiconductor processing chamber. The methods may include forming a plasma within the remote plasma region to generate plasma effluents of the fluorine-containing precursor. The methods may include flowing the plasma effluents into a processing region of the semiconductor processing chamber. A substrate may be positioned within the processing region. The substrate may include a trench formed through stacked layers including alternating layers of silicon nitride and silicon oxide. The methods may include isotropically etching the layers of silicon nitride while substantially maintaining the silicon oxide.

Abstract: The invention relates to a system for controlling torque in a wind turbine. In one embodiment, the system includes a rotor, a rotor driveline coupled with the rotor and an electrical generator, the rotor driveline including a coupler, a torque control mechanism, a transmission system, the torque control mechanism comprising a variable torque converter, a switching mechanism and at least one energy storage system. During operation, the variable torque converter actuate the positive force and/or torque acting on rotor driveline in order to achieve the desired rpm when the set point of desired rpm is higher than the present value of the said rpm, and also to actuate the negative force and/or torque acting on the rotor driveline in order to achieve the desired rpm when the set point of desired rpm is lower than the present value of the said rpm.

Abstract: The present invention provides a turbine control system and method. The turbine control system includes at least one control means accommodated on a turbine rotor wherein the control means is actuated by a controller in a first or second direction on a plane of the rotor turbine to control a rate of change of moment of inertia of the turbine and thereby controlling the operation of the turbine. The invention also provides a turbine farm including a plurality of turbines operating to provide a maximum and stable power output. The farm includes a master controller configured for controlling the operation of each of the plurality of turbines and individual controller of the turbines efficiently.
