Patent number: 6879478Abstract: A surge counter/detector apparatus includes current sensors communicating with power lines to sense a surge condition. A trigger circuit communicates with the current sensors and outputs a first signal in response to the sensed surge condition. The trigger circuit is reset and enabled by a second signal in order to enable subsequent output of the first signal. A processor detects the first signal from the trigger circuit and responsively increments and displays a count value at a display. The processor provides the second signal having a first state to reset the trigger circuit and a second state to enable the trigger circuit. The processor includes a timer to vary a time between (a) detecting the first signal, and (b) resetting and enabling the trigger circuit.Type: GrantFiled: October 31, 2002Date of Patent: April 12, 2005Assignee: Eaton CorporationInventors: Anthony-Cernan Mendoza, Dalibor Kladar, James Funke, Chi Thuong Ha, Henryk Jan Dabrowski, Mieczyslaw Bandura

Patent number: 6748344Abstract: A meter includes an EEPROM storing a scaling factor; a divider providing a first analog voltage from an electrical system; an analog to digital converter (ADC) converting the first analog voltage to a first digital value; and a processor. The processor includes a first routine calculating the scaling factor; an input circuit for the first routine, and a second routine retrieving the scaling factor from the EEPROM and adding the scaling factor to the first digital value to provide a sum for a display. The first routine calculates the scaling factor by subtracting a second digital value from a larger third digital value, which represents a nominal voltage value. The second digital value is converted by the ADC from a second analog voltage from the divider, that receives a larger third analog voltage representing the nominal voltage value.Type: GrantFiled: April 29, 2002Date of Patent: June 8, 2004Assignee: Eaton CorporationInventors: Anthony C.

Patent number: 6636409Abstract: A surge protection device includes terminals adapted to receive a power source voltage and surge protection circuits, each of which includes a thermal fuse spring, one or more metal oxide varistors (MOVs), and one or more fuse traces corresponding to the MOVs. The thermal fuse spring, one of the fuse traces and the corresponding one of the MOVs are electrically interconnected in series between the terminals, in order to form a series electrical connection therebetween. The thermal fuse spring is adapted to disconnect the series electrical connection between the terminals under first fault conditions including a first current of first duration through one of the MOVs. The thermal fuse spring and each of the fuse traces are adapted to cooperatively disconnect a corresponding one of the series electrical connections between the terminals under second fault conditions including a second greater current of second lesser duration through one of the MOVs.Type: GrantFiled: April 16, 2001Date of Patent: October 21, 2003Assignee: Eaton CorporationInventors: Dalibor Kladar, James Funke, Chi Thuong Ha, Anthony-Cernan Mendoza, Mieczyslaw Bandura, Mahoud Ghanem

Patent number: 6411482Abstract: A surge protector is for electrical connection between one or more power lines and one or more loads. The surge protector includes an input for electrical connection to the power line and an output for electrical connection to the load. A circuit electrically interconnects the output with the input for passing power therebetween. A metal oxide varistor protects the load from surges or transients on the power line. A voltage monitoring circuit detects an occurrence of an overvoltage event on the power line. A charged capacitor is shorted by the series combination of a fuse and a MOSFET switch to open the fuse and, thereby, permanently record the occurrence of the overvoltage event.Type: GrantFiled: February 15, 2000Date of Patent: June 25, 2002Assignee: Eaton CorporationInventor: James Funke

Patent number: 6226162Abstract: A surge suppression network for single and multiphase ac systems has a voltage clamping device connected in series with a gated crowbar device across the supply voltage in parallel with the load to be protected. A trigger circuit gates the crowbar device on in response to a specified rate of change of the supply voltage indicative of a surge. For higher levels of surge current shunting, pluralities of clamping devices and crowbar devices can be connected in parallel with a single trigger circuit simultaneously turning on all of the crowbar devices for each phase. For crowbar devices such as TRIACs with different response characteristics to positive and negative surges and for unipolar devices such as SCRs, positive and negative subnetworks are connected in anti-parallel across the load.Type: GrantFiled: June 2, 1999Date of Patent: May 1, 2001Assignee: Eaton CorporationInventors: Dalibor Kladar, Chi Thuong Ha, Anthony Cernan Mendoza, James Funke

Patent number: 5845852Abstract: A fuel injector includes an injector body and a three-way control valve having a valve element movable between first and second positions in the injector body. A check is disposed in the injector body and is movable to inject fuel when the control valve is in the second position and to block fuel injection when the control valve is in the first position. An actuator is selectively operable to move the valve element between the first and second positions. The injector includes a single clearance fit located in the control valve wherein the clearance fit is not exposed to a substantial pressure differential when the control valve is in the first position.Type: GrantFiled: November 15, 1996Date of Patent: December 8, 1998Assignee: Caterpillar Inc.Inventors: Donald John Waldman, Keith Edward Lawrence, Steven James Funke, Craig William Lohmann

Patent number: 5784236Abstract: The invention provides a circuit to protect an AC motor powered by a Variable Frequency Drive (VFD) from overvoltages caused by reflected waves. A full wave bridge rectifier circuit across the lines of the motor to be protected provides rectified voltage output to a capacitor, across which a low resistance discharge resistor in series with one or more zener diodes is attached. When an overvoltage above the clamping voltage of the zener diode(s) occurs across the protected lines, the zener diode(s) will conduct, causing the excess charge across the capacitor to discharge through the resistor until the voltage drops below the clamping voltage of the diode(s).Type: GrantFiled: May 22, 1997Date of Patent: July 21, 1998Assignee: Tycor International Corp.Inventors: Dale Tardiff, James Funke

Patent number: 5698846Abstract: A method and device for detecting when a clipping component within a transient voltage surge suppressor (TVSS) or TVSS with high frequency electrical noise attenuation (both called surge suppression device or SPD) has failed open. The method comprises the steps of: collecting airborne debris and gases generated when the SPD fails open in a space; subjecting the space to a particle detector; diagnosing the detection of particles by the particle detector and communicating the diagnosis to an appropriate signal generator. The device comprises a container within which at least the clipping components of the SPD reside; an open air space within the container; particle detector associated with the space within the container; and an electronic control unit electronically associated with the particle detector to receive a message that airborne debris or gas particles are within the air space inside the container and then to communicate and, as required, act on such.Type: GrantFiled: October 18, 1995Date of Patent: December 16, 1997Assignee: Tycor InternationalInventor: James Funke
