  • Patent number: 12257594
    Abstract: A mix chamber for a plural component sprayer is configured to receive first and second component materials and emit a spray of a resulting plural component material. The mix chamber includes a chamber body extending between a first end and a second end and including flat lateral sides. A ramp feature is disposed proximate the first end and is configured to contact and push first and second side seals, respectively, away from a body axis as the mix chamber shifts in a first direction through a cartridge bore to increase a gap between the first side seal and the second side seal such that the first side seal engages the first flat lateral side and the second side seal engages the second flat lateral side.

  • Publication number: 20250073480
    Abstract: Disclosed are a timeline-based navigation feature and a channel selection feature. The timeline-based navigation feature allows the user to visually identify significant events during an episode and quickly navigate the display of data to those significant events. Embodiments of such feature allow a user to quickly see that there is a shock delivered, for example, and click on that part of a timeline navigator to advance the detailed display of data to that point in the episode. The data channel selection feature enables selection of display channel(s) from among a set of available data channels. Embodiments of such feature enable a selection and/or deselection of various channels for display to minimize display of extraneous data and/or to select preferred channels of data for review.

  • Patent number: 12242094
    Abstract: Each wire 12 of a wire grid polarizer can include a cap 22 on a reflective rib 21. The cap 22, with dimensions and material as specified herein, can protect the reflective rib 21 from corrosion and can improve performance of the wire grid polarizer. The cap 22 can be located on the distal end 21d and the pair of sidewalls 21S of the reflective rib 21. Cap 22 chemistry can include CO, C?O, COO, aluminum fluoride, and aluminum oxide. Each cap 22 can have a maximum thickness ThCS on the sidewall 21S of the reflective rib 21 in an upper 50% (above plane 31) of the wire 12 farthest from the substrate 11. Each cap 22 can have a maximum thickness ThCS on the sidewall 21S that is greater than a maximum thickness ThCD of the cap 22 on the distal end 21d.

  • Patent number: 12189161
    Abstract: A method of making a polarizer can include applying a liquid with solid inorganic nanoparticles dispersed throughout a continuous phase, then forming this into a different phase including a solid, interconnecting network of the inorganic nanoparticles. This method can improve manufacturability and reducing manufacturing cost. This method can be used to provide an antireflective coating, to provide a protective coating on polarization structures, to provide thin films for optical properties, or to form the polarization structures themselves.

  • Publication number: 20240139595
    Abstract: A golf accessory tool is securable to a golf club and includes three panels that are attached to each other with two hinges. The panels rotate about the hinges between an open position for receiving a golf club and a closed position surrounding the golf club. Two of the panels can be secured to each other with a securing mechanism to attach the tool to the club in the closed position. The panels include recesses and cavities for receiving golf accessories, such as a divot repair tool and ball markers, with the accessories removably coupled to the tool. A golf grip includes a golf accessory portion at a proximal end of the grip that similarly includes recesses and cavities for receiving accessories and the accessories removably coupled to the grip.

  • Publication number: 20240061147
    Abstract: A metasurface optical device can include an array of pillars 13 on a first-side 11f of a substrate 11 aligned with an aperture 15 of, or proximate to, a blocking-layer 12. The blocking-layer 12 can located on the first-side 11f of the substrate 11, on a second-side 11s of the substrate 11 opposite of the first-side 11f, or both. The blocking-layer 12 can prevent light from transmitting through the device in undesirable locations. The blocking-layer 12 can be opaque to incident light and can include an absorptive-layer. Thus, the blocking-layer 12 can have dual functions—blocking and absorbing light.

  • Patent number: 11814207
    Abstract: An automated packaging station is capable of being used to package objects. The automated packaging station includes a supply of web material, a surface (202), an aperture (206) therein, and a closing system. The automated packaging station is configured to form the web material into a pouch. The aperture (206) is configured such that an object can be inserted therethrough. The automated packaging station is configured to bias open the pouch beneath the surface such that the object inserted through the aperture falls into the pouch. The closing system is configured to close the pouch to form a package around the object in response to the object being inserted through the aperture. The object is capable of being shipped to a recipient in the package.
