Patent number: 12553754Abstract: Disclosed is a fast-response sensor system to measure a fluid vector in a plurality of dimensions. This system, known as ‘MAST’ (for MEMS Anemometry Sensing Tower), utilizes microelectromechanical (MEMS) hot-wire devices to produce a solid-state, lightweight, and robust flow sensor system suitable for, e.g., real-time wind estimation onboard a UAV. The MAST uses three through eighteen polygonally-arranged microscale flow sensors to determine the fluid's vector's direction and magnitude.Type: GrantFiled: September 12, 2023Date of Patent: February 17, 2026Assignee: The Trustees of Princeton UniversityInventors: Nathaniel Simon, Alexander Piqué, David Snyder, Kyle Ikuma, Anirudha Majumdar, Marcus Hultmark

Publication number: 20250314831Abstract: A photonic integrated circuit (PIC) includes one or more silicon nitride edge couplers directly formed on exposed portions of the buried oxide layer. Directly forming the SiN edge couplers on the highly-planar buried oxide layer provides structures with significantly reduced minimal dimension possibilities (as compared to SiN edge couplers within the PIC oxide stack), allowing for a beam emitted from the “SiN-on-box” coupler to exhibit a mode field diameter of larger size than associated with conventional SiN edge couplers positioned on dielectric over the silicon waveguide layer.Type: ApplicationFiled: May 4, 2023Publication date: October 9, 2025Applicant: Aayuna, Inc.Inventors: Kalpendu Shastri, Sriram Tyagarajan, Ravinder Kachru, David Snyder, Anujit Shastri, Rao Yelamarty

Patent number: 12242109Abstract: A dual-layer coupling arrangement comprises a first coupling waveguide disposed within a photonic integrated circuit (at a position over an included optical signal waveguide) and a second coupling waveguide disposed above the first coupling waveguide. The first and second coupling waveguides are formed to exhibit splitter configurations that terminate as a pair arms separated by a distance suitable for creating beams that would coincide with a circular mode field of the core region of a coupling optical fiber. The vertical spacing between the first and second coupling waveguides is set so that the pairs of beams exiting from the terminating arms of the coupling waveguides coincide with a circular mode field.Type: GrantFiled: January 13, 2022Date of Patent: March 4, 2025Assignee: Aayuna Inc.Inventors: Ravinder Kachru, Anujit Shastri, Rao Yelamarty, Sriram Tyagarajan, David Snyder, Kalpendu Shastri

Publication number: 20240269032Abstract: A roller apparatus including a frame and a rotatable roller. A roller is rotatably mounted on the front portion of the frame. A handle extends from either side of the frame. During use, the hand of the user can be positioned below the rear portion of the frame and extend through opening in the frame adjacent the handle. The handle can be grasped by the user. A bottom surface of the rear portion of the frame contacts the wrist, hand or arm of the user. The roller contacts an area of the portion of a person or animal to be massaged having the advantage that additional leverage is applied from additional pressure applied to the roller from the user's wrist.Type: ApplicationFiled: October 19, 2023Publication date: August 15, 2024Inventor: David Snyder
