Patent number: 11384000Abstract: An adaptive electrokinetic dewatering system for dewatering slurry and soil deposits, including tailings deposits and a control system therefor. The control system automatically determines an optimal applied power specification, including sets of power parameters to be applied to the deposit being dewatered and when to apply each set of power parameters during the electrokinetic dewatering process. Furthermore, the control system automatically adjusts the applied power specification throughout the course of the dewatering process to account for the changing properties of the deposit. The control system determines the applied power specifications and adjustments to be made to them by simulating the electrokinetic dewatering process using a simulator which incorporates the latest measurements of the electrical, physical and chemical properties of the deposit being dewatered.Type: GrantFiled: February 7, 2019Date of Patent: July 12, 2022Assignee: Electro-Kinetic Solutions, Inc.Inventors: James Micak, Ed Hanna, Clare Armstrong, Barna Szabados, Steven Spencer, Doug Kimzey

Patent number: 9538625Abstract: Systems and methods that provide improved control of addressable lighting fixtures. Individual lighting units have assigned schedules defining the power levels for the unit at various times of the day. Adjustments to a scheduled level for each unit may be made depending on predefined exceptions, ambient daylight, conservation commands, override instructions, and boost signals. Individual occupants of the building are associated with sets of individual lighting units. An override command received by the system and associated with a particular individual occupant is applied to the individual lighting units with which the individual occupant is associated.Type: GrantFiled: March 3, 2014Date of Patent: January 3, 2017Assignee: COOPER TECHNOLOGIES COMPANYInventors: Barna Szabados, Roumanos Dableh

Patent number: 7598631Abstract: An addressable power switch for selectively connecting a device to main power in response to command instructions received over a control bus. The control bus supplies a low voltage power source and the addressable power switch includes an energy storage device and charge circuit for deriving a charge current from the low voltage power source and charging the energy storage device. The addressable power switch also includes a latching relay for connecting the device to main power. The change in state of the latching relay is realized through controlling discharge of the energy storage device, which supplies an energy pulse upon discharge. The switch may be used in connection with addressable lighting systems.Type: GrantFiled: January 29, 2007Date of Patent: October 6, 2009Assignee: Fifth Light Technology Ltd.Inventors: Barna Szabados, Roumanos Joseph Dableh, Kyle Van Bavel

Patent number: 6538395Abstract: A current controlled dimmer for controlling the output intensity of a fluorescent lamp with a magnetic ballast. The current controlled dimmer generates an AC current which follows the shape of the AC line voltage for the fluorescent lamp. The light intensity output of the fluorescent lamp is controlled by varying the amplitude of the AC current. The AC current is generated using a pulse width modulator (PWM) to modulate the AC line voltage. The current controlled dimmer 10 utilizes a feedback control loop which applies proportional and integral (PI) control to the PWM modulation. In another embodiment of the current controlled dimmer, the AC current is generated by rectifying the AC line voltage and modulating the rectified voltage by a pulse width modulator (PWM) into positive and negative cycles to generate a 60 Hz AC current signal.Type: GrantFiled: April 12, 2001Date of Patent: March 25, 2003Assignee: 1263357 Ontario Inc.Inventor: Barna Szabados

Patent number: 6133696Abstract: A dimmer applies a phase-controlled AC voltage to a lighting assembly which includes a fluorescent lamp operated with a magnetic ballast. A microprocessor performs a calibration routine in which the phase angle used in phase control is increment from 0 toward 180 degrees. The microprocessor monitors current conducted by the lighting assembly in response to each incrementing, effectively determining an operative range of phase angles free of flickering or drop-out. During steady-state operation, the microprocessor converts nominal power settings into corresponding phase angle settings within the operative range, preventing operation in undesirable states.Type: GrantFiled: October 1, 1997Date of Patent: October 17, 2000Assignee: Joao F.
