Patent number: 11978690Abstract: A cooling system is described. The cooling system includes a bottom plate, a support structure, and a cooling element. The bottom plate has orifices therein. The cooling element has a central axis and is supported by the support structure at the central axis. A first portion of the cooling element is on a first side of the central axis and a second portion of the cooling element is on a second side of the central axis opposite to the first side. The first and second portions of the cooling element are unpinned. The first portion and the second portion are configured to undergo vibrational motion when actuated to drive a fluid toward a heat-generating structure. The support structure couples the cooling element to the bottom plate. At least one of the support structure is an adhesive support structure or the support structure undergoes rotational motion in response to the vibrational motion.Type: GrantFiled: July 8, 2022Date of Patent: May 7, 2024Assignee: Frore Systems Inc.Inventors: Vikram Mukundan, Suryaprakash Ganti, Seshagiri Rao Madhavapeddy, Ananth Saran Yalamarthy, Prathima Kapa

Patent number: 11940505Abstract: We use the AC Hall effect to characterize a magnetic field at an unknown frequency (or frequencies). The current to the Hall sensor is driven at a known frequency f. The output Hall voltage is characterized in a frequency range from f1 to f2 (with f<f1<f2 and f2?f1<2f). This provides a measurement of the magnetic field in a frequency range from f1?f to f2?f. The resulting measurement of magnetic field spectral components is phase-independent and requires no prior knowledge of exact magnetic field frequency.Type: GrantFiled: May 27, 2022Date of Patent: March 26, 2024Assignee: The Board of Trustees of the Leland Stanford Junior UniversityInventors: Anand Vikas Lalwani, Ananth Saran Yalamarthy, Maximillian Holliday, Hannah Alpert, Carla Nicole Pinzon, Debbie G.

Publication number: 20230200000Abstract: A fluid flow system is described. The fluid flow system includes an actuator and a chamber having a feature therein. The actuator is configured to vibrate in response to a driving signal. The chamber is in communication with the actuator. The chamber is characterized by a fluidic resonant frequency. Vibration of the actuator tends to drive a fluid through the chamber. The feature is within the chamber and obstructs direct flow of the fluid within the chamber such that the fluidic resonant frequency is less than a nominal fluidic resonant frequency that would exist without the feature.Type: ApplicationFiled: December 15, 2022Publication date: June 22, 2023Inventors: Suryaprakash Ganti, Vikram Mukundan, Ananth Saran Yalamarthy, Seshagiri Rao Madhavapeddy, Prabhu Sathyamurthy, Narayana Prasad Rayapati
