  • Patent number: 11920501
    Abstract: An energy storage system converts variable renewable electricity (VRE) to continuous heat at over 1000° C. Intermittent electrical energy heats a solid medium. Heat from the solid medium is delivered continuously on demand. An array of bricks incorporating internal radiation cavities is directly heated by thermal radiation. The cavities facilitate rapid, uniform heating via reradiation. Heat delivery via flowing gas establishes a thermocline which maintains high outlet temperature throughout discharge. Gas flows through structured pathways within the array, delivering heat which may be used for processes including calcination, hydrogen electrolysis, steam generation, and thermal power generation and cogeneration. Groups of thermal storage arrays may be controlled and operated at high temperatures without thermal runaway via deep-discharge sequencing. Forecast-based control enables continuous, year-round heat supply using current and advance information of weather and VRE availability.

  • Patent number: 11919847
    Abstract: The invention relates to an efficient, high-throughput method of converting monoterpenes to high performance aviation fuel blendstocks. The method is a one pot, two-step process that includes a dehydration step followed by a hydrogenation step. Both steps can proceed without the use of solvents. Use of biosynthetically generated monoterpenes by this method produces sustainable aviation fuel blendstocks having applications that include use as a full-performance or an ultra-performance jet fuel blendstock.

  • Patent number: 11921284
    Abstract: A zoom system includes a collection optic L1 and a reflective Fresnel Lens L2 having a variable focal length. The reflective Fresnel Lens L2 is implemented with a MEMS MMA in which the mirrors tip, tilt and piston form and alter the reflective Fresnel Lens to focus light at a common focal point to set the variable focal length f2, hence the magnification M. In different embodiments, the zoom system may be configured to be “focal” or “afocal”. In the focal system, both L1 and L2 are fixed such that the system affects the net convergence or divergence of the magnified beam. In an afocal system, a mechanism is used to translate L2 to maintain a separation between L1 and L2 of d=f1+f2 as f2 is varied to change the magnification M.

  • Publication number: 20240069630
    Abstract: In one embodiment, a method includes detecting that a user has donned a headset, capturing eye-tracking data of the user's eyes using sensors, using the eye-tracking data to estimate six degrees-of-freedom offsets between the headset as donned and a predefined optimal donning position, using facial landmarks in images of a lower portion of the user's face obtained by cameras to estimate a pitch offset between the headset as donned and the predefined optimal donning position, and generating, based on the six degrees-of-freedom offsets and pitch offset, instructions to guide the user to adjust the headset to be closer to the predefined optimal donning position.
