  • Patent number: 11911178
    Abstract: A system for treating atrial fibrillation includes a memory configured to store a baseline measurement of an atrial fibrillation characteristic of a patient and a post administration measurement of the atrial fibrillation characteristic of the patient. The post administration measurement is obtained subsequent to administration of a reactive oxygens species (ROS) scavenger to the patient. The system also includes a processor operatively coupled to the memory and configured to determine a change between the baseline measurement and the post administration measurement of the atrial fibrillation characteristic. The processor is further configured to identify, based on the determined change, one or more hot spots of atrial fibrillation, where the one or more hot spots comprise target areas for treatment of the atrial fibrillation.

  • Publication number: 20240058664
    Abstract: Disclosed golf club heads include a weight channel positioned in the sole and defining a path along the sole. A weight member positioned in the weight channel can be adjusted to any of a range of selectable positions to adjust mass properties of the golf club head. A fastener secures the weight member in any of the selectable positions, while the fastener itself, regardless of where the weight member is positioned along the path, is secured to the body at a fixed location that is independent of the position of the weight member along the path. Part of the weight channel and weight member can be covered by an overhanging portion of the sole, which can form a sit pad. The overhanging portion can be part of a composite sole insert.

  • Publication number: 20240002938
    Abstract: Disclosed herein is a system and method for increasing the fidelity of measured genetic data, for making allele calls, and for determining the state of aneuploidy, in one or a small set of cells, or from fragmentary DNA, where a limited quantity of genetic data is available. Poorly or incorrectly measured base pairs, missing alleles and missing regions are reconstructed using expected similarities between the target genome and the genome of genetically related individuals. In accordance with one embodiment, incomplete genetic data from an embryonic cell are reconstructed at a plurality of loci using the more complete genetic data from a larger sample of diploid cells from one or both parents, with or without haploid genetic data from one or both parents. In another embodiment, the chromosome copy number can be determined from the measured genetic data, with or without genetic information from one or both parents.

  • Patent number: 11847590
    Abstract: Communications over short-range connections are used to facilitate whether access to resources is to be granted. For example, upon device discovery of one of an electronic user device and an electronic client device by the other device over a Bluetooth Low Energy connection, an access-enabling code associated with a user device or account can be evaluated for validity and applicability with respect to one or more particular resource specifications. User identity can be verified by comparing the user against previously obtained biometric information.

  • Patent number: 11847924
    Abstract: Methods, systems, and apparatus, including computer programs encoded on computer storage media, for reserving airspace for UAV operations. In some implementations, a flight planning system can reserve and allocate airspace for unmanned aerial vehicle (UAV) operations. For example, a UAV operator device can submit a flight plan to the flight planning system. The flight planning system can submit a flight authorization request to an airspace management system to reserve airspace necessary for the flight plan. The flight planning system can receive approval and/or a reservation of the airspace for the flight plan from the airspace management system, generate a flight data package, and send the flight data package to the operator's device.

  • Publication number: 20230400269
    Abstract: A firearm system is provided. A pump-action firearm, such as a shotgun, includes a buffer attached to a trigger housing. The buffer consists of a resilient or semi-resilient material and is positioned such as to face towards an opening the receiver in which the magazine tube is partially received. The buffer includes a contoured bottom surface and an upper surface, configured in a way which shortens the space available within an opening of a receiver while accommodating the loading of shells into a magazine tube. Upon moving a shell into the opening, such as by pumping the action, the shell impacts the buffer, which stabilizes the shell prior to being lifted by an elevators. For shorter shells, this reduces the risk of a jamming event. For longer shells, the buffer is configured to compress to accommodate the additional length.
