Apparatus And Method For Detection Of Latent Faults In Redundant Systems
US Patent:
5325062, Jun 28, 1994
Filed:
Jul 10, 1992
Appl. No.:
7/911510
Inventors:
Gerard E. Bachand - Cherry Valley MA
Peter A. Goodwin - Wayland MA
Peter A. Goodwin - Wayland MA
Assignee:
Sequoia Systems, Inc. - Marlboro MA
International Classification:
G01R 3102
US Classification:
324537
Abstract:
Apparatus and method are provided for fault detecting in an electrical system such as a redundant or fault-tolerant system. A current receiving device connected in shunt or in series in such a system draws electric current from the electrical system being monitored. During normal operation, while current is still flowing properly through the system being monitored, an appropriate indication such as a continued series of pulses is generated, which is interpreted as indicating proper operation. If that current flow is cut off, indicating a fault condition, then the apparatus and method provide an appropriate signal (such as cutoff of the series of pulses) to a communication system which provides an appropriate indication to an external location. The current receiving device can be a relaxation oscillator together with another device which can be a pulse generator, an L-C energy transfer arrangement, a bridge circuit including an inductor, a two-winding inductor or a capacitor. The latter such device can be connected in shunt or in series with the electrical system being monitored.
Magnetic Core For Medical Procedures
US Patent:
7824324, Nov 2, 2010
Filed:
Jul 27, 2005
Appl. No.:
11/191106
Inventors:
Mark Edward Riehl - Doylestown PA, US
Kenneth P. Ghiron - Allentown PA, US
Leo P. Carbonneau - Nashua NH, US

Assignee:
Neuronetics, Inc. - Malvern PA
International Classification:
A61N 2/00
US Classification:
600 9
Abstract:
The inventive technique include a system, method and device for treating a patient. The inventive system includes a magnetic field generating device created using a powdered ferromagnetic. The system further includes a circuit in electrical communication with the magnetic core, and a power source in electrical communication with the circuit. The ferromagnetic powder core may be manufactured by at least one of the following: machining, pressing, molding, gluing, and extruding. Also, the ferromagnetic powder core may have a distributed gap structure, where the gap structure operates to focus the magnetic field between pole faces of the magnetic device.
