  • Patent number: 12245817
    Abstract: The invention provides devices and methods for non-invasive monitoring and measuring of intraocular pressure (IOP) of a subject. Embodiments include a lens that is adapted to fit on the subject's eye, a microstructure disposed in or on the lens, the microstructure having at least one feature that exhibits a change in shape and/or geometry and/or position on the lens in response to a change in curvature of the lens. When the curvature of the lens changes in response to a change in IOP, a corresponding change in shape and/or geometry and/or position of the feature may be used to determine the change in IOP. The change in the feature is detectable in digital images of the lens taken with a mobile electronic device such as a smartphone.

  • Patent number: 12248327
    Abstract: The present invention discloses a method for UAV path planning in urban airspace based on a safe reinforcement learning (RL) algorithm called shield-DDPG, which combines a shield model with a DDPG algorithm and pertains to the field of UAV technologies. The method takes an attractive force from the destination point into account when an action is selected, which improves the convergence speed of the algorithm and also improve the efficiency of UAV path planning. More importantly, the method provided by the present invention can effectively verify safety of an action in terms of the air collision risk and the ground impact risk, and ensure that a final output of the algorithm is a safe optimal solution. Therefore, the present invention can effectively solve the problem that when the RL algorithm is used for UAV path planning, it is difficult to ensure the safety of the learning or execution process due to the lack of hard constraints.

  • Patent number: 12247978
    Abstract: The present disclosure includes a multiplexed peptide assay to generate an epitope-resolved view of antibody reactivity across all human coronaviruses (CoVs). PepSeq accurately classifies SARS-CoV-2 exposure status and reveals epitopes across the Spike and Nucleocapsid proteins. Two of these represent recurrent reactivities to conserved, functionally-important sites in the S2 subunit of Spike, regions that we show are also targeted for the endemic CoVs in pre-pandemic controls. At one of these sites, we demonstrate that the SARS-CoV-2 response strongly and recurrently cross-reacts with the endemic virus hCoV-OC43. The disclosed epitope-resolved analysis reveals new CoV targets for the development of diagnostics, vaccines and therapeutics, including a site that may have broad neutralizing potential.

  • Patent number: 12250502
    Abstract: A control signal may be modulated on an optical wave. A transmitter may transmit the control signal to a switch/processor location. At the remote node, the control signal is received and converted from an optical signal to an electrical signal to drive the switch/processor. To provide electrical power at the switch/processor location, optical power is transmitted from a distance and converted to electrical power using a series of PDs. Monitoring tones may be sent to the remote node and fed back to the transmitter to realize an operation state and detect a bias drift. Accordingly, an OSP function at a remote node is enabled without using any local electrical power supply.
