ALEXANDRIA, Va., Jan. 29 -- United States Patent no. 12,213,071, issued on Jan. 28, was assigned to TRANE INTERNATIONAL INC. (Davidson, N.C.).
"Mesh routing of sleepy sensor data" was invented by Joel C. VanderZee (La Crosse, Wis.).
According to the abstract* released by the U.S. Patent & Trademark Office: "HVAC components having improved efficiency are described. In one embodiment, excessive sleep current draw in a battery-powered device having a microcontroller is detected by measuring a voltage drop across a MOSFET device coupled in a forward-conducting orientation in series between the battery and the microcontroller, causing a transistor to conduct when the voltage drop exceeds a predetermined threshold to generate a first trigger si...
