Patent number: 11839007Abstract: An enhanced smart lighting system (ESLS) for use in buildings without neutral wire connections for wall switches. The ESLS entails both a no-neutral wire smart lighting switch (NNWSLS) and a physically separate load adapter. The NNWSLS includes a sensing, control, or communication system (SSCCS) such as integrated WiFi. The load adapter mitigates electrical fluctuations which may be induced in a power load (for example a lightbulb) by the smart lighting switch, particularly when the smart lighting switch is nominally powered off but still has some current flow. The load adapter is an intermediary between the power load and a conventional load receptacle. The load adapter has an integrated dummy load configured in parallel with the power load. The dummy load provides an electrical pathway for low levels of electricity which run through the light socket even when the NNWSLS is set to an “off” configuration.Type: GrantFiled: September 3, 2020Date of Patent: December 5, 2023Assignee: SAVANT TECHNOLOGIES LLCInventors: Mason Hall, Tomislav J. Stimac, Aijun Wang

Publication number: 20150009674Abstract: Thermal management techniques and methods for various types of structures that require a thermal property, such as thermal conductivity and/or flame retardance, and have a surface in proximity to a source of thermal energy. Such a structure includes a substrate formed of a metallic material or a thermally conductive plastic material, and a white fluoropolymer layer directly on a surface of the substrate without a discrete adhesive layer therebetween. The white fluoropolymer layer defines an outermost surface of the structure, has a reflectivity of greater than 95%, and has a thickness sufficient to inhibit degradation of the thermal property of the structure resulting from impingement of the surface by the thermal energy.Type: ApplicationFiled: July 3, 2013Publication date: January 8, 2015Inventors: Dengke CAI, Thomas CLYNNE, Péter JEZSOVICZKI, Mark Edward KAMINSKI, Elizabeth Anne SKIERSKI, Tomislav J.
