Filed:

Jun 7, 1996

Appl. No.:

08/659919

Inventors:

Jay Law - Denver CO
William Borkan - North Miami Beach FL
Lance Ehren - Dallas TX
George Van Campen - Fort Lauderdale FL
John Erickson - Plano TX

Assignee:

Advanced Neuromodulation Systems, Inc. - Plano TX

International Classification:

A61N 134

US Classification:

607 46, 607 59

Abstract:

An electronic stimulation system is used to control pain over multiple regions of a patients body. The system has one or more percutaneous leads, each having multiple electrodes, implanted within the patients epidural space parallel to the axis of the spinal cord. The leads are connected to either a totally implanted system or a radio frequency system. The system is able to treat pain over different regions of a patients body by âsimultaneouslyâ stimulating the patient with at least three different stimulation settings. âSimultaneousâ stimulation involves sequentially stimulating the patient with the multiple stimulation settings such that the patient receives the cumulative effect of each stimulation setting, while not perceiving the transition from one stimulation setting to another.

Abstract:

An electronic stimulation system is used to control pain over multiple regions of a patient's body. The system has one or more percutaneous leads, each having multiple electrodes, implanted within the patient's epidural space parallel to the axis of the spinal cord. The leads are connected to either a totally implanted system or a radio frequency system. The system is able to treat pain over different regions of a patient's body by “simultaneously” stimulating the patient with at least three different stimulation settings. “Simultaneous” stimulation involves sequentially stimulating the patient with the multiple stimulation settings such that the patient receives the cumulative effect of each stimulation setting, while not perceiving the transition from one stimulation setting to another.

Appl. No.:

12/974669

Inventors:

John W. Erickson - Crystal Lake IL, US
James A. Erickson - Crystal Lake IL, US
John Walter Erickson - Crystal Lake IL, US

Assignee:

Boltswitch, Inc. - Crystal Lake IL

International Classification:

H01R 9/22

US Classification:

439709, 200 5109, 200237, 361823

Abstract:

A terminal reversing block mounts to a standard electrical disconnect device such as a circuit breaker or a pullout switch. The disconnect device has a housing which defines a cavity that faces in one direction for receiving a cable. Front and rear contacts are in the housing, one of which extends into the cavity for engagement with a cable. A terminal reversing block has a housing with at least one pocket which faces in a direction other than the opposite of the direction in which the disconnect device's cavity faces. A terminal collar disposed in the terminal reversing block pocket is engageable with a cable inserted into the pocket. A terminal in the reversing block has a mating portion and a connecting portion. The connecting portion engages the terminal collar. The mating portion engages one of the front and rear contacts of the electrical disconnect device.

International Classification:

G06F015/173

US Classification:

709/224000

Abstract:

A method and system provide for the processing and display of telemetry information received from pre-flight and in-flight sensors for launch vehicles. The system is configured to decommutate telemetry information received from the launch pad and launch vehicle such that it may be transmitted over a data network to one or more graphical user interfaces for real-time display. The system is further configured to archive telemetry information received such that it may be retrieved and viewed or combined in various displays with real-time data so as to analyze launch vehicle conditions.

Appl. No.:

5/815543

Inventors:

John Walter Erickson - Crystal Lake IL
John W. Erickson - Crystal Lake IL

Assignee:

Boltswitch, Inc. - Crystal Lake IL

International Classification:

B65D 344

US Classification:

200153N

Abstract:

A dual switch actuator mechanism for coordinated actuation of two high-current switches, each of which includes a switch operator mechanism for opening and closing the switch in response to rotation of a switch operator shaft. The switches are mounted adjacent to each other with their switch operator shafts in aligned paraxial spaced relation. The dual switch actuator mechanism includes a rotatable main shaft positioned between and in aligned paraxial relation to the switch operator shafts. A Geneva drive plate having an arcuate bearing surface is affixed to the main shaft; two drive pins are mounted on the drive plate. Two modified Geneva follower plates are provided, each affixed to one of the switch operator shafts. Each follower plate has a drive slot for receiving one of the drive pins and an arcuate bearing surface which is complementary to the drive plate bearing surface. For a given neutral position of the main shaft, each drive pin is positioned in the entrance of a follower plate drive slot and the bearing surfaces of both follower plates engage the drive plate bearing surface.

Assignee:

Boltswitch, Inc. - Crystal Lake IL

International Classification:

H01H 326
H01H 328

US Classification:

335 76

Abstract:

A motor assembly for the switch operator mechanism of a high-current low-voltage bolted-pressure load-break switch; the switch operator mechanism includes spring drive means for rapidly driving the movable contact of the switch to its closed and opened positions, a main drive shaft, a drive linkage between the main drive shaft and the spring drive means, and trip means for actuating the spring drive means to open the switch. The motor assembly includes an electric motor, an operating shaft and a first transmission means including a mutilated ratchet element drivingly connecting the motor to the operating shaft. A second transmission means couples the operating shaft to the main drive shaft of the switch-operating mechanism for closing the switch. An electrical circuit is provided for automatically de-energizing the motor during switch closure.

International Classification:

H01H 902

H01H 1904
H01H 2104

US Classification:

200304

Abstract:

A high current, low voltage, load-break switch of the type which is installed in a housing having an access door. The switch comprises a fixed contact, a movable contact which is movable between a closed position in bolted pressure contact with the fixed contact and an open position which is displaced from the fixed contact. A mechanism is provided for rapidly opening and closing the switch by driving the movable contact to its closed position and also to its open position. A transparent shield is supported across the front of the switch contacts to visually expose the switch contacts when the access door to the housing is open while providing protection in the event of electrical arcing and mechanical failure of the switch contacts.
