Patent number: 11397055Abstract: A vapor-chamber that includes a porous microstructure sheet with varying surface energy across different regions to optimize utilization of a working fluid. Modulating the surface energy of the porous microstructure sheet can minimize the amount of the working fluid that becomes trapped in the condenser region(s) and maximize an aggregate thin-film evaporation area of the working fluid in the evaporator region(s). The condenser region of the vapor-chamber is treated so that the internal surfaces have low surface energy. For example, the treatment may cause the condenser region to become hydrophobic to minimize the amount of fluid that becomes trapped in the condenser. The evaporator region is treated so that the internal surfaces have high surface energy. For example, the treatment may cause the evaporator region to become hydrophilic to induce the formation of large numbers of robust (e.g., dry-out resistant) thin-film evaporation sites.Type: GrantFiled: February 1, 2021Date of Patent: July 26, 2022Assignee: MICROSOFT TECHNOLOGY LICENSING, LLCInventors: Shahar Ben-Menahem, Tzu-Yuan Lin, Michael Nikkhoo

Patent number: 10989919Abstract: A pad shape for a support assembly is optimized to provide universal fitting characteristics to Head-Mounted Display (HMD) devices. The pad shape enables a display of a single HMD device to be reliably aligned within multiple users' fields-of-view notwithstanding significant variations of shape and size between these users' heads. Optimal positioning of the display within the multiple users' fields-of-view may be achieved by positionally constraining the HMD device against a portion of the head that varies relatively slightly as compared to other portions of the head. The contact pad includes a curved region having a shape defined by a high order polynomial that corresponds to an empirically determined best fit surface. Empirically determining one or both of the best fit surface or the high order polynomial may include aligning a plurality of “forehead” point clouds that map the geometries of a sample set of users' foreheads.Type: GrantFiled: May 18, 2018Date of Patent: April 27, 2021Assignee: Microsoft Technology Licensing, LLCInventors: Igor Markovsky, Shahar Ben-Menahem, Michael Nikkhoo, Tzu-Yuan Lin

Patent number: 10962298Abstract: A two-phase thermodynamic system includes a porous microstructure sheet to increase an aggregate thin-film evaporation area of a working fluid. The porous microstructure sheet may be disposed at a liquid-vapor boundary of the working fluid. The porous microstructure sheet has “micro” pores through which the working fluid flows from a liquid flow path on one side of the porous microstructure sheet to a vapor flow path on the other side of the porous microstructure sheet. Individual pores induce the working fluid to form thin-film evaporation regions. The porous microstructure sheet may have a pore density so as to increase an aggregate thin-film evaporation area of the working fluid. In this way, the overall thermal resistance across all liquid-vapor interfaces (menisci) of the working fluid is substantially decreased over conventional vapor chamber.Type: GrantFiled: September 28, 2018Date of Patent: March 30, 2021Assignee: Microsoft Technology Licensing, LLCInventors: Shahar Ben-Menahem, Tzu-Yuan Lin, Michael Nikkhoo

Publication number: 20190353431Abstract: A thermodynamic system includes a compensational wick geometry to enhance fluid flow between a condenser region and an evaporator region. Geometric features are modulated between a condenser region and an evaporator region to increase capillary forces within wicking structures without excessively increasing hydraulic resistance to the liquid flowing through these return-path wicking structures. The thermodynamic system may include a liquid flow path having channels extending from the condenser region to the evaporator region. At various segments of the channels, individual cavity sizes are reduced to induce capillary action toward the evaporator region. Various geometric features compensate for these cavity size reductions, to mitigate the effects of increased resistances to liquid flow.Type: ApplicationFiled: May 18, 2018Publication date: November 21, 2019Inventors: Shahar BEN-MENAHEM, Igor MARKOVSKY, Tzu-Yuan LIN, Michael NIKKHOO

Patent number: 10107513Abstract: Modeling the behavior of an enclosure for use by a control system of an HVAC system is described. A model for the enclosure that describes the enclosure's behavior for use by the control system is updated based on weather forecast data. The weather forecast data can include predictions more than 24 hours in the future, and can include predictions on temperature, humidity and/or dew point, solar output, precipitation. The model for the enclosure can also be updated based on additional information and data. The model for the enclosure can be updated based also on an enclosure model stored in a database, and/or enclosure information from a user. The model can be updated based on active testing of the enclosure which can be performed automatically or in response to user input. The testing can include heating and/or cooling the enclosure at times when the enclosure is not likely occupied.Type: GrantFiled: February 24, 2015Date of Patent: October 23, 2018Assignee: Google LLCInventors: Anthony Michael Fadell, Matthew Lee Rogers, Kipp Avery Rogers, Abraham K.
