Publication number: 20190196069Abstract: Described herein is a system and method for tuning light scatter in an optically functional porous layer of an LED. The layer comprises a non-light absorbing material structure having a plurality of sub-micron pores and a polymer matrix. The non-light absorbing material forms either a plurality of micron-sized porous particles dispersed throughout the layer or a mesh slab, wherein a plurality of sub-micron pores is located within each micron-sized porous particle or forms an interconnected network of sub-micron pores within the mesh slab, respectively. A polymer matrix, such as a high refractive index silicone fills the plurality of sub-micron pores creating an interface between the materials. Refractive index differences between the materials allow for light scatter to occur at the interface of the materials. Light scatter can also be decreased as a function of temperature, creating a system for tuning light scatter in both an off state and on state of an LED.Type: ApplicationFiled: December 22, 2017Publication date: June 27, 2019Applicant: Lumileds LLCInventors: Marcel Rene BOHMER, Jacobus Johannes Franciscus Gerardus HEUTS, Daniel ESTRADA, Kentaro SHIMIZU

Publication number: 20180049132Abstract: A device location is determined, and the location of an area of interest that is a geographic area referred to as a geo-fence is identified. Multiple geo-fences can be identified by the device, and different geo-fences can be associated with different programs on the device. An operating system of the device implements multiple different periods of operation for the device, including a conservation period during which certain programs are not typically scheduled to run, and an execution period during which such programs are typically scheduled to run. A system identifies geo-fence events, which occur when the device enters or exits the geo-fence. The system maintains a record of the geo-fence events for each of multiple geo-fences, and provides to a program selected ones of those geo-fence events at a time when the program is scheduled to run on the device during an execution period of the operating system.Type: ApplicationFiled: October 6, 2017Publication date: February 15, 2018Applicant: Microsoft Technology Licensing, LLCInventors: Frank Gorgenyi, Daniel Estrada Alva, Fernando Gonzalez, Sanjib Saha
