Patent number: 10042051Abstract: Systems and techniques are described for tsunami detection and warning using coastal radar systems designed primarily for the real-time mapping of ocean surface currents. These radar systems are configured to detect an approaching tsunami in the system's “near field,” i.e., the near-shore region over which the radar system observes the sea surface.Type: GrantFiled: April 27, 2016Date of Patent: August 7, 2018Assignee: CODAR Ocean Sensors, Ltd.Inventors: Donald E. Barrick, Belinda J. Lipa, James Isaacson

Publication number: 20070118103Abstract: A removable semi-insulating sheet for use in self-limiting electrosurgical return semi-insulating sheet for use with electrosurgery. Through the selection of impedance characteristics for the electrode materials of the principal body of the semi-insulating sheet, and through tailoring of semi-insulating sheet geometries, the return electrode of the present invention is self-regulating and self-limiting as to current density and temperature rise so as to prevent patient trauma. The semi-insulating sheet has an effective bulk impedance equal to or greater than about 4,000 ?·cm. The effective bulk impedance of the sheet may arise from resistive components, capacitive components, inductive components, or combinations thereof The configuration of the presently described return electrode allows the electrode to self-limit the electrode's current densities, thereby preventing burning of a patient during surgery.Type: ApplicationFiled: January 23, 2007Publication date: May 24, 2007Applicant: Mega-Dyne Medical Products, Inc.Inventors: Richard Fleenor, David Kieda, James Isaacson, Paul Borgmeier

Publication number: 20070060919Abstract: Systems, methods, and instruments associated with controlling the operating modes of an electrosurgical instrument using control signals delivered in a wireless manner from the electrosurgical instrument to an electrosurgical generator. The electrosurgical instrument transmits wireless control signals to the electrosurgical generator to initiate delivery of electrosurgical energy. The control signals are delivered to the electrosurgical generator without the need for a conductive cord extending between the electrosurgical generator and the electrosurgical instrument. The energy is delivered to the electrosurgical instrument, in response to the wireless control signals, along a path through an electrode and the physician utilizing the electrosurgical instrument and/or a conductive path external to the physician. The electrode upon which the physician rests provides a path for the electrosurgical energy and optionally prevents burning of the physician during an electrosurgical procedure.Type: ApplicationFiled: October 25, 2006Publication date: March 15, 2007Applicant: MEGADYNE MEDICAL PRODUCTS, INC.Inventors: James Isaacson, Paul Borgmeier, Treymayne Mikalauski

Publication number: 20070049916Abstract: An electrosurgical return electrode for use in electrosurgery. The return electrode is self-limiting and self-regulating as to current temperature and temperature rise so as to prevent patient trauma. According to one aspect of the invention, an inductor is coupled in series with the electrosurgical return electrode. The inductor is configured to optimize the flow of the electrosurgical current by minimizing the effective bulk impedance of the electrosurgical return electrode when the amount of contact area between the patient and the electrosurgical return electrode is sufficient to conduct electrosurgery. According to another aspect of the present invention, a conductor member is adapted for use with circuitry that indicates to a user when the contact area between the patient and the self-limiting member and/or return electrode is below a given threshold.Type: ApplicationFiled: September 29, 2006Publication date: March 1, 2007Applicant: MEGADYNE MEDICAL PRODUCTS, INC.Inventors: James Isaacson, Paul Borgmeier

Publication number: 20060191990Abstract: An electrosurgical apparatus having a counter/lockout mechanism that monitors the number of sterilization/use cycles the electrosurgical apparatus undergoes and indicates the number of sterilization/use cycles that have actually been performed. The counter/lockout mechanism includes a temperature actuated element actuated in response to each sterilization cycle and a mechanically actuated element in response to a use cycle to effectuate a change of one or a plurality of indicia. The counter/lockout mechanism causes a single increment or decrement for each sterilization/use cycle that has been completed while also impeding use of the electrosurgical apparatus when the electrosurgical apparatus has undergone a predetermined number of sterilization/use cycles. In one embodiment, the distance of movement of the mechanically actuated element when fully actuated is greater than the distance the indicator moves when illustrating a change in the number of remaining uses.Type: ApplicationFiled: May 5, 2006Publication date: August 31, 2006Inventors: James Isaacson, Paul Borgmeier, William Miller

Publication number: 20060045242Abstract: A custom announcement is efficiently deployed to a local exchange switching platform, such as a switch from the Nortel DMS family. Initially, an announcement provider creates a binary file representing the requested announcement and stores the file on a server accessible to a telecommunications carrier. A representative of the telecommunications carrier then downloads the file from the server. Subsequently, a specific record length is set to override a default record length in a program that communicates with the local exchange switching platform. The program then electronically transfers the binary announcement file to the local exchange switching platform using the specific record length.Type: ApplicationFiled: September 1, 2004Publication date: March 2, 2006Applicant: SBC Knowledge Ventures, L.P.Inventor: James Isaacson

Publication number: 20050113817Abstract: An electrosurgical return electrode for use in electrosurgery. The return electrode is self-limiting and self-regulating as to maximum current and temperature rise to prevent patient trauma. An inductor is coupled in series with the return electrode. The inductor counteracts at least a portion of the impedance of the return electrode and the patient to optimize the flow of the current when the amount of contact area between the patient and the return electrode is sufficient to perform electrosurgery. The inductor may also be variable to allow the overall impedance of the electrosurgical circuit to be adjusted and tuned to work properly and safely with a particular patient and the other equipment used to perform electrosurgery. A conductor member operates with circuitry that indicates to a user when the contact area between the patient and the self-limiting member and/or return electrode is below a given threshold.Type: ApplicationFiled: November 21, 2003Publication date: May 26, 2005Inventors: James Isaacson, Paul Borgmeier

Patent number: 6774837Abstract: A bistatic radar system (100), method and computer program (178) are provided for mapping of oceanic surface conditions. Generally, the system (100) includes at least one transmitter (102) and at least one receiver (106) located separate from one another, and each having a local oscillator locked to a Global Positioning System (GPS) signal received by a GPS synchronization circuit (134) to provide the necessary coherency between the transmitted and received signals. Preferably, the present invention enables an existing backscatter radar systems to be quickly and inexpensively upgraded to a bistatic radar system (100) through the addition of a transmitter (102) and/or receiver (106) separate from the backscatter radar system, the GPS circuit (134), and use of the computer program (178) and method of the present invention.Type: GrantFiled: October 27, 2003Date of Patent: August 10, 2004Assignee: Codar Ocean Sensors, Ltd.Inventors: Donald E. Barrick, Peter M. Lilleboe, Belinda J. Lipa, James Isaacson
