Publication number: 20230355467Abstract: A system for monitoring and/or reviewing transitions between types of medical treatment events provided for a patient during a rescue effort includes a medical device and a computing device. The medical device includes a chest compression sensor configured to receive time-correlated signals representative of chest compressions. The medical device is configured to generate a case file for the rescue effort comprising times of occurrence for a plurality of medical events. The computing device is configured to: receive the case file for the rescue effort, select and determine the time of occurrence for a first event of the plurality of medical events from the case file, select and determine the time of occurrence for a second event of the plurality of medical events, and determine a transition time between the time of occurrence of the first event and the time of occurrence of the second event.Type: ApplicationFiled: May 8, 2023Publication date: November 9, 2023Inventors: Gregory R. Norton, Nicole M. Spahn, James R. Fetterolf, Brian M. Smith

Patent number: 7208684Abstract: The present invention is directed to a high voltage, insulated electrical power cable suitable for use adjacent to one or more low power signal communications conductors in metal or plastic conduit or raceway. In one preferred embodiment, the power cable includes a first group of one or more conductors for supplying power and a power conductor insulation jacket enclosing the first group of one or more conductors. The power conductor insulation jacket includes a soft magnetic material that functions as an electromagnetic field shield in the radio frequency range of approximately 1 megahertz to 400 megahertz thereby protecting the integrity of signals transmitted on the adjacent signal communications conductors.Type: GrantFiled: September 3, 2004Date of Patent: April 24, 2007Assignee: Ulectra CorporationInventors: James R. Fetterolf, Sr., Charles S. Blichasz, William L. Donmoyer, Arthur H. Heuer, Alberto E. Planas, Sr., Alberto E. Planas, Jr.

Patent number: 7205480Abstract: The present invention is directed to a hybrid electrical cable providing for power transmission or distribution and data and/or voice signal communications. In one preferred embodiment, the hybrid electrical cable includes a power cable having a group of one or more high voltage power conductors for conducting power and one or more groups of low power signal conductors for transmitting voice and/or data and/or control signals. The cable further includes a power cable insulation jacket overlying the group of one or more power conductors. The power cable insulation jacket includes a soft magnetic material, preferably a soft ferrite magnetic material, for RF absorption. The cable additionally includes an outer grounded metallic jacket or sheath overlying the power cable, the power cable insulation jacket and the one or more groups of low power conductors.Type: GrantFiled: December 13, 2005Date of Patent: April 17, 2007Assignee: Ulectra CorporationInventors: James R. Fetterolf, Sr., Charles S. Blichasz, William L. Donmoyer, Arthur H. Heuer, Alberto E. Planas, Sr., Alberto E. Planas, Jr.

Patent number: 5558534Abstract: A self-sacrificing latching system for a pair of intermatable electrical connectors, such as a plug and receptacle, which incorporates a mechanism for unlatching same by the application of a maximum predetermined separating force, such as may be the result of an accident to the plug and receptacle. A first electrical connector includes a pair of flexible arms projecting axially therefrom, where the free end includes a bifurcated portion, while the second electrical connector includes a forward ramp surface against which the flexible arms initially ride to effect mating of the connectors. Further, there is a rearward surface slightly angled, i.e. on the order of about 4.degree. to 10.degree., from a base toward the ramp surface, and a metal spring arm mounted within the second electrical connector in close proximity to the base of the rearward surface.Type: GrantFiled: November 22, 1994Date of Patent: September 24, 1996Assignee: The Whitaker CorporationInventors: Michael D. Sarkady, Jason M. Reisinger, William V. Pauza, James R. Fetterolf, Sr., James E. Connell, Jr.

Patent number: 5449298Abstract: This invention relates to a latching system for a pair of intermatable electrical connectors, such as a plug and receptacle, which incorporates a mechanism for unlatching same by the application of a maximum predetermined separating force, such as may be the result of an accident, to the plug and receptacle. The system comprises a first electrical connector having a pair of flexible arms projecting axially therefrom, where the free ends of the arms include slot means for engaging complementary arms within the second electrical connector. The second electrical connector includes a forward ramp surface against which the flexible arms initially ride to effect mating of the connectors, a rearward surface slightly angled, i.e. on the order of about 4.degree. to 10.degree., from a base toward the ramp surface, and a metal spring arm mounted within the second electrical connector in close proximity to the base of the rearward surface. In the mated condition the spring arm engages the slot means.Type: GrantFiled: June 30, 1994Date of Patent: September 12, 1995Assignee: The Whitaker CorporationInventors: James R. Fetterolf, Sr., Harold W. Kerlin, Jason M. Reisinger

Patent number: 4310213Abstract: A kit for an electrical connector is disclosed for use in connecting a first electrical device to a second electrical device; for example, connecting an audio microphone to a CB radio. The kit includes a cable guard member receiving therethrough a cable from the first device; first and second terminal members, with the first terminal members connected to conductors of the cable; and a connector housing having cavities extending therethrough to receive the second terminal members. The second terminal members are loaded into the cavities and the first terminal members subsequently inserted therein in mating engagement with the second terminal members. When the connector housing and cable guard member are connected together and the housing plugged into a socket mounted in the second electrical device, electical connection is established between the first and second devices. The kit further includes cable strain relief means and coupling means to secure the connector to a mating connector.Type: GrantFiled: June 28, 1979Date of Patent: January 12, 1982Assignee: AMP IncorporatedInventors: James R. Fetterolf, Sr., Donald L. Metzger, Clair W. Snyder, Jr., James H. Wise
