Publication number: 20180168854Abstract: An improved heating pad which minimizes or eliminates skin burns due to improper uses in one or more of several ways: by monitoring a total electric power input or output of the heating pad; by monitoring an absolute temperature of each surface of the heating pad; by monitoring a temperature difference between each surface of the heating pad, where a small temperature difference indicates that both sides of the heating pad are covered; and/or by monitoring the duty cycle of a heating element, where a large off portion of the duty cycle indicates both sides of the heating pad are covered.Type: ApplicationFiled: November 22, 2017Publication date: June 21, 2018Applicant: TRIODYNE SAFETY SYSTEMS, LLC.Inventors: Ralph Lipsey Barnett, James R.

Patent number: 7988604Abstract: A safety cable system for a fitness device including a resistance load and a user interface device. A redundant cable apparatus connects the resistance load to the user interface device for lifting the resistance load by a force applied to the user interface device. The redundant cable apparatus comprises two cables extending in redundant cable paths between the resistance load and the user interface device. The two cables can share the resistance load or one of the cables can be dormant until failure of the other cable.Type: GrantFiled: November 13, 2009Date of Patent: August 2, 2011Assignee: Triodyne Safety Systems LLCInventor: Ralph L. Barnett

Patent number: 7013743Abstract: The subject invention is directed to methods, processes and decisions on test outcomes for testing for faulty, therefor dangerous, performance of zero speed indicators that are used to control the opening of barriers guarding moving machine components. The indicators may be tested by removing them from the components during operation without shutting down production or in certain situations the indicators may be tested during the run down phase of the components caused by machine stop initiations. The tests allow to anticipate and hence prevent hazardous opening of barriers due to a faulty zero speed indication. Additionally, the invention is directed to testing of the insertion of motion interference devices in conjunction with zero speed indicators, both of which must perform correctly in order to permit the unlocking and opening of the protective barrier. There are included various exemplary devices for effecting the testing function.Type: GrantFiled: March 28, 2003Date of Patent: March 21, 2006Assignee: Triodyne Safety Systems, LLCInventors: Ralph L. Barnett, Theordore Liber

Patent number: 6865755Abstract: Missing drain covers used in connection with swimming pools, spas and/or other applications expose humans and animals to discharge ports in the drains that can develop near vacuums which eviscerate, entrap the body and entangle hair. A drain cover is disclosed that releases an elastomeric plug in the neighborhood of the drain upon removal of the drain cover. The plug becomes entrained in the discharge flow and eventually plugs up the smaller diameter discharge port eliminating vacuum hazards by checking all discharge flow and pressure.Type: GrantFiled: January 16, 2003Date of Patent: March 15, 2005Assignee: Triodyne Safety Systems, LLCInventor: Ralph Lipsey Barnett
