Patent number: 8199024Abstract: A safety circuit used in low-voltage connecting systems leaves the two low-voltage systems disconnected until it determines that it is safe to make a connection. When the safety circuit determines that no unsafe conditions exist and that it is safe to connect the two low-voltage systems, the safety circuit may connect the two systems by way of a “soft start” that provides a connection between the two systems over a period of time that reduces or prevents inductive voltage spikes on one or more of the low-voltage systems. When one of the low-voltage systems has a completely-discharged battery incorporated into it, a method is used for detection of proper polarity of the connections between the low-voltage systems. The polarity of the discharged battery is determined by passing one or more test currents through it and determining whether a corresponding voltage rise is observed.Type: GrantFiled: September 14, 2009Date of Patent: June 12, 2012Assignee: Energy Safe Technologies, Inc.Inventors: Jeffrey Baxter, Brent Baxter, Michael Baxter, Ted Holbrook

Patent number: 8169762Abstract: Current transformer relays having dual functions as current transformers and electromechanical switches are described. The current transformer relay includes a relay coil and a conducting loop concentric with the relay coil. Additional functions are thus provided in addition to the main relay switching function or functions. The concentric nature of the relay coil and the conducting loop create a current transformer between these elements. The additional functions include the ability to measure an alternating current (AC) current conducted by the conducting loop, the ability to detect and interpret an information signal imposed on power lines connected to the conducting loop, the ability to induce or impose an information signal on the conducting loop for transmission to power lies connected to the conducting loop, and the ability to measure a differential current between currents carried by the conducting loop and a second concentric conducting loop.Type: GrantFiled: April 20, 2009Date of Patent: May 1, 2012Assignee: Energy Safe Technologies, Inc.Inventors: Jeffrey Baxter, Brent Baxter, Michael Baxter, Ted Holbrook

Patent number: 8139337Abstract: Systems and methods that provide improved detection of series fault conditions are described. The systems provide an increased range of response possibilities upon detection of such conditions. Solid-state temperature sensors are utilized and may be connected to a printed circuit board integrated with supply wire terminals, thus providing electronic circuitry controlling the response to over-temperature events while simultaneously keeping the temperature sensors in close proximity with the location of potential over-heating events. Electronic sensors in accordance with implementations of the present invention detect overheating conditions at temperatures more quickly because of the close proximity of the sensors to locations of potential overheating, thereby improving the safety of electrical wiring devices and fixtures. Additionally, the threshold temperature for response can more easily be selected or controlled to be at a variety of temperatures to improve safety.Type: GrantFiled: September 23, 2008Date of Patent: March 20, 2012Assignee: Energy Safe Technologies, Inc.Inventors: Michael Baxter, Glenn Spacht, Brent Baxter

Publication number: 20050219252Abstract: A buffer logic within a memory module having the capability to carry out a test of another memory module to which it is coupled via a point-to-point bus through autonomously storing and transmitting a test pattern across that point-to-point bus to the other memory module, while further employing another buffer logic that is interposed between the two memory modules to pass on the test pattern, but intercept a signal received from the other memory module during the test and pass on an indication of the receipt of that signal to an analysis device to monitor the test.Type: ApplicationFiled: March 30, 2004Publication date: October 6, 2005Inventors: Mark Buxton, Brent Baxter
