Publication number: 20250193559Abstract: An example system for passive sensing includes a coupled pair of resonators including a sensor resonator and a reader resonator, the sensor resonator including a resistor a loss associated with the resistor, and the reader resonator including a MOS cross-coupled pair that implements a nonlinear gain of the reader resonator via compressive saturation of negative resistance. An amplitude detector measures the amplitude of oscillations associated with the reader resonator, and the negative resistance is determined based on the measured amplitude of oscillations associated with the reader resonator when the measured amplitude reaches a steady state, i.e., when the gain of the reader resonator balances the loss of the sensor resonator. The resistance associated with the resistor of the sensor resonator may be determined based on the determined negative resistance. When the resistor is a resistive sensor, indications of measurements by the resistive sensor may be determined in this way.Type: ApplicationFiled: December 1, 2021Publication date: June 12, 2025Inventors: Ada Shuk Yan Poon, Siavash Kananian, George Alexopoulos

Publication number: 20250134372Abstract: A wireless electroencephalogram (EEG) recording system is provided, comprising: one or more two-channel electrodes; an analog-to-digital converter (ADC) configured to capture EEG data detected by the one or more electrodes; a digital controller configured to encode the captured EEG data into a single-bit series, and generate a packet using the single-bit series; and a radio frequency (RF) transmitter configured to transmit the packet to an external receiver. In some examples, the wireless EEG recording system further includes a battery powering the one or more ADCs, the digital controller, and the RF transmitter. For instance, in some examples, the wireless EEG recording system further includes an adhesive patch configured to be attached to the head of a patient, wherein the one or more two-channel electrodes, a chip including the ADC, the digital controller and the RF transmitter, and the battery are each attached to the adhesive patch.Type: ApplicationFiled: February 3, 2023Publication date: May 1, 2025Inventors: Ada Shuk Yan Poon, Cheng Chen

Patent number: 12040848Abstract: Described herein are methods of making and using and apparatus for wirelessly communicating data and providing power, particularly from a location exterior to a body and to an implantable device disposed within a body with tissue. The described embodiments provide apparatus and methods for efficiently transfer data and power between an external transceiver and an (implanted) biomedical device. The method is to modulate power carrier, which wirelessly powers the device, using an asynchronous modulation scheme, such as amplitude shift keying (ASK) modulation, with minimal modulation depth in order to not disrupt the power flow. The digital data is encoded in the pulse width, eliminating the need for synchronization to the power carrier signal and further minimizing the power consumption necessary for data transfer. Additionally, a reverse backscatter method for obtaining data from the implant is described that has flexible, low power operation.Type: GrantFiled: August 23, 2022Date of Patent: July 16, 2024Assignee: The Board of Trustees of the Leland Stanford Junior UniversityInventors: Anatoly Anatolievich Yakovlev, Daniel Pivonka, Ada Shuk Yan Poon, Teresa H.

Publication number: 20240042222Abstract: Implantable devices and/or sensors can be wirelessly powered by controlling and propagating electromagnetic waves in a patient's tissue. Such implantable devices/sensors can be implanted at target locations in a patient, to stimulate areas such as the heart, brain, spinal cord, or muscle tissue, and/or to sense biological, physiological, chemical attributes of the blood, tissue, and other patient parameters. The propagating electromagnetic waves can be generated with sub-wavelength structures configured to manipulate evanescent fields outside of tissue to generate the propagating waves inside the tissue. Methods of use are also described.Type: ApplicationFiled: August 24, 2023Publication date: February 8, 2024Inventors: Ada Shuk Yan Poon, Alexander Jueshyan Yeh, Yuji Tanabe, John Ho, Sanghoek Kim

Patent number: 11865123Abstract: This invention is based on the discovery that many eye conditions associated with aging are mediated at least in part by cells bearing a senescent phenotype. Senescent cells accumulate with age, and express factors that contribute to the pathophysiology of age related conditions. The data show that in age-matched patients, the severity of age-related conditions correlates with the abundance of senescent cells, and that clearing senescent cells can help abrogate the condition. Small molecule drugs that remove senescent cells from affected tissue in the eye are provided that have special efficacy in treating ophthalmic conditions. They not only inhibit progression of the disease, they can also reverse some of the pathophysiology—such as neovascularization and vaso-obliteration—that lead to vision loss. These senolytic agents have an appropriate dose and specificity profile to be effective in the clinical management of previously intractable ophthalmic conditions.Type: GrantFiled: August 25, 2021Date of Patent: January 9, 2024Assignee: Unity Biotechnology, Inc.Inventors: Pam Tsuruda, Jill Hopkins, Harry Sweigard, Yan Poon, Jamie Dananberg, Daniel Marquess, Nathaniel David
