Patent number: 11598546Abstract: Apparatus, systems and methods for ascertaining the occupancy of a building are presented. The building is divided into one or more control zones which correspond to physical areas of the building associated with controllable modules, such as HVAC units, lighting, irrigation, or other environmental features such as fountains, music, video, and the like. Zone parameters define how zone devices shall react to the number of occupants located in the particular zone. A building control system detects individual mobile devices in and around the building, and determines the locations of each device by using trilateration and/or location services. The identified mobile devices act as proxies for building occupants. The locations of these devices are correlated with the locations of the zones in the building, and the building control system then adjusts the operating parameters of the zone based on the number of devices present in the zone.Type: GrantFiled: December 22, 2015Date of Patent: March 7, 2023Assignee: Trane International Inc.Inventors: Paul Edmund Haines, Thomas A. Fletcher, Bryan Kinney, John C. Olson

Publication number: 20190237647Abstract: A method of manufacturing a conductive layer includes the step of dissolving an organic semiconductor polymer in a first solvent, the first solvent being an aromatic or heterocyclic compound comprising one or more electron-rich carbon atom(s) and/or heteroatom(s). The method also includes dissolving a dopant in a second solvent, the second solvent being a polar solvent. The method also includes mixing the solutions of the organic semiconductor polymer and the dopant to form a dispersion comprising doped conductive polymer particles suspended in the solvent blend. The method also includes depositing the dispersion by a solution deposition technique to form a conductive layer. The solution deposition technique is preferably an inkjet printing, dispense printing or drop casting method. The dispersion provides a stable ink composition for the manufacturing of thick and uniform layers with excellent conductivity and thermopower, and allows simple fabrication of thermoelectric legs with enhanced performance.Type: ApplicationFiled: August 29, 2017Publication date: August 1, 2019Applicants: Cambridge Display Technology Limited, Sumitomo Chemical Company LimitedInventor: Thomas Fletcher
