20120241988 | String-Thick-Plates Pack for Use in Cooling Tower and Fabrication Thereof - The present invention involves a string-thick-plates pack formed of a multiplicity of string-thick-plates for application as fill media in cooling tower. The individual string-thick-plates are assembled into the fill pack by joining male and female attachment tabs on the frame of the string-thick-plates. The string-thick-plate is in a thick rectangular plate shape and consists of two vertical-string-screens on its both sides, which are fabricated by winding one long string over the rectangular frame in longitudinal direction of the string-thick-plate. Intervals between adjacent strings of the vertical-string-screens on the string-thick-plate are designed to preserve a maximum optimized surface area of the strings able to obtain a maximum cooling efficiency of the string-thick-plate. The string-thick-plates pack is designed to be installed upright and on the slant in the cooling tower of the cross-flow type and counter-flow type, respectively. Warm water sprayed on the top perforated plate of the string-thick-plates pack imbibes into the holes on the top plate of the string-thick-plates pack by surface tension of the strings suspending over the holes and then flows down on the surface of the strings by gravity. During its flowing down on the surface of the strings, the water is cooled through evaporation and convection heat transfer mechanisms driven by contacting with ambient cooling air traveling in a direction transverse or on the slant to the descent of the water on the surface of the strings by means of a natural, induced, or forced draft. The string-thick-plates pack of the present invention has a more than 10% higher efficiency, much easier installation, and much longer service life, compared with those of the current film fills. | 09-27-2012 |

20080205096 | CONTROL SYSTEM AND METHOD FOR A UNIVERSAL POWER CONDITIONING SYSTEM - A new current loop control system method is proposed for a single-phase grid-tie power conditioning system that can be used under a standalone or a grid-tie mode. This type of inverter utilizes an inductor-capacitor-inductor (LCL) filter as the interface in between inverter and the utility grid. The first set of inductor-capacitor (LC) can be used in the standalone mode, and the complete LCL can be used for the grid-tie mode. A new admittance compensation technique is proposed for the controller design to avoid low stability margin while maintaining sufficient gain at the fundamental frequency. The proposed current loop controller system and admittance compensation technique have been simulated and tested. Simulation results indicate that without the admittance path compensation, the current loop controller output duty cycle is largely offset by an undesired admittance path. At the initial simulation cycle, the power flow may be erratically fed back to the inverter causing catastrophic failure. With admittance path compensation, the output power shows a steady-state offset that matches the design value. Experimental results show that the inverter is capable of both a standalone and a grid-tie connection mode using the LCL filter configuration. | 08-28-2008 |

20130009589 | SYSTEM AND METHOD FOR CONTROLLING FOUR-QUADRANT OPERATION OF A SWITCHED RELUCTANCE MOTOR DRIVE THROUGH A SINGLE CONTROLLABLE SWITCH - Regulating the speed of a two-phase switched reluctance machine (TPSRM) rotor includes selecting either a motoring mode or braking mode of operation for the TPSRM, regulating the rotor speed, when the motoring mode is selected, using a control signal cooperatively produced by a speed control feedback loop and a current control feedback loop; and regulating the rotor speed, when the braking mode is selected, using a control signal produced by the current control feedback loop without the cooperation of the speed control feedback loop. The speed control feedback loop uses an established speed control signal and a signal indicative of the rotor's speed to dynamically adjust a first parameter governing the control signal. The current control feedback loop uses an established current control signal and a signal indicative of the current flowing through a stator winding of the TPSRM to dynamically adjust a second parameter governing the control signal. | 01-10-2013 |

20110046693 | Deep Brain Stimulation Device Having Wireless Power Feeding By Magnetic Induction - Provided is a deep brain stimulation (DBS) device having power wirelessly fed by a magnetic induction to form a rotating magnetic field using a rotating magnetic field disk installed inside a hat put on a patient and generate induced power using an induction coil plate fixed underneath a scalp of the patient to be combined with the rotating magnetic field, to drive electrodes implanted into a brain of the patient so as to correct abnormal motor and sensory functions of the patient using power wirelessly fed from an outside into a body of the patient. The DBS device includes: a hat module which is installed inside a hat put on a head of the o patient to generate a rotating magnetic field; and an implantation module which is implanted through a skull under a scalp to contact a nervous system of the patient and combined with the rotating magnetic field of the hat module to stimulate the cerebral nerve using induced power generated by the magnetic induction. | 02-24-2011 |
