  • Patent number: 12283389
    Abstract: An adjustable collimator device for collimating a beam of energy emitted from a radiation source is disclosed. The collimator has an elongated plate-like body with a front-end and a rear-end. The collimator has a first set of emission apertures equally spaced around a central axis of the body that defines a zero-degree position. The first set of emission apertures are placed on the rear-end of the body and are configured to receive and sample a beam of energy entering the adjustable collimator device. A second set of apertures are placed proximate the front-end of the body. The second set of apertures are adjustable such that a first of the second set of apertures can be configured to have a first angular offset relative to the zero-axis and a second of the second set of apertures can be configured to have a second angular offset relative to the zero-axis.

  • Patent number: 12272945
    Abstract: Multi-semiconductor SSPCs that solve bus level problems affecting systems as well as controller level problems affecting individual multi-semiconductor SSPCs are disclosed. Bus level and controller level problems adversely affect multi-semiconductor SSPCs and their associated systems. The disclosed multi-semiconductor SSPCs solve both bus level and controller level problems by implementing controlled rate-change of voltage (dv/dt) ramp-on rate, to ensure that the voltage on the input bus does not collapse when a multi-semiconductor SSPC is commanded closed and that a minimum amount of power is being dissipated evenly across the switching semiconductors.

  • Patent number: 12265587
    Abstract: Connections among two different entities are identified by processing a collection of documents to identify one or more documents that contain co-occurring mentions of each of the two different entities. This relationship may be graphically displayed in a user interface with an icon or the like for each of the two entities, along with a graphical link interconnecting the entities. The graphical link can be an active element of the user interface that responds to user interactions by providing access to evidence within the collection of documents that substantiates the connection between the two entities. In one aspect, a search input form field in a user interface may be used to explicitly request documents that substantiate a relationship between two entities. In another aspect, a user may ground entity mentions by explicitly selecting documents that mention an entity of interest.

  • Publication number: 20250083001
    Abstract: A cast cup can include a forward portion of a golf club head, including a hosel, a face portion, and forward portions of a crown, sole, heel and toe. A rear ring can be formed separately from the cast cup and coupled to heel and toe portions of the cast cup to form a metallic club head body, such that the club head body defines a hollow interior region, a crown opening, and a sole opening. The cast cup and rear ring can be cast of titanium alloys. Composite crown and sole inserts can then be coupled to the crown opening and sole opening. The face portion of the cast cup can have a desirably complex geometry. The rear surface of the face portion of the cast cup can be modified before the rear ring is attached.

  • Publication number: 20250072948
    Abstract: An electrode treatment device includes an electrode strip arranged in the shape of a helix with a first end of the electrode strip attached to an elongate flexible body, such as a catheter tube, and a second end of the electrode strip attached to a flexible shaft that extends from the body. When the helical electrode is contracted around the body and/or shaft, the device may be less than 2 mm in diameter to facilitate endoluminal insertion and treatment of gastrointestinal or lung tissue, for example. The shaft is rotatable relative to the body to radially expand the helix to a deployed position in apposition to target tissue for electrosurgical treatment (e.g., treatment in a lumen). The electrode strip may consist of conductive foil or may comprise a flexible printed circuit with one or more electrodes formed thereon. The device may be operated by a robotic manipulator.

  • Patent number: 12233318
    Abstract: Golf club heads are provided for selectively increasing or optimizing the coefficient of restitution (COR) at likely impact locations on the striking face of the golf club heads, while simultaneously maintaining characteristic time (CT) below a threshold value in those likely impact locations. By analyzing historical impact locations of a large cross-section of golfers, golf club head COR values can be increased or optimized in preferential locations on the striking face, such as using weighting factors for a predefined set of locations on the striking face. Therefore, instead of increasing COR uniformly across the face and/or increasing COR at impact locations on the face where golfers are unlikely to strike the golf ball, the sweet spot of the golf club head can be increased at the impact locations where golfers typically strike the golf ball.

  • Publication number: 20250058183
    Abstract: A cast cup can include a forward portion of a golf club head, including a hosel, forward portions of a crown, sole, heel, and toe, and a face portion or an opening to receive a face insert. A rear ring can be formed separately from the cast cup and coupled to heel and toe portions of the cast cup to form a rigid club head body, such that the club head body defines a hollow interior region, a crown opening, a sole opening, and/or face opening. The cast cup and rear ring can be made of different materials, including various metals, composites, and polymers. Composite crown, sole, and/or face inserts can be coupled to the crown, sole, and/or face openings. Weights can be coupled to the cast cup and to the rear ring. The face can have a complex variable thickness geometry.

  • Publication number: 20250034644
    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.
