  • Patent number: 12312256
    Abstract: A device that treats water with multiple wavelengths of light an optionally sound in order to modify the structure of the water. The device may have two light panels on two different sides of a transparent container that holds water to be treated. Each light panel may have light sources that emit three different wavelengths of light. Specific wavelength combinations have been found to produce the desired structural changes in water. Hydrogen and/or oxygen, and/or minerals and/or chromophores may be added to the water before or during treatment. Potential sources of hydrogen and oxygen may be an electrolysis unit attached to or integrated into the light treatment device, or a hydrogen bearing mineral that may be added to the water. Experiments that treat and then freeze the water demonstrate a novel structure via the formation of unusual crystalline forms in the frozen, treated water.

  • Publication number: 20250133886
    Abstract: Solid-state lighting devices, and more particularly, symmetrical lead frame structures for two-pin light emitting diode (LED) packages and methods for making the same are disclosed. The symmetrical lead frame structure can include a pair of leads that include symmetrical split cup portions that collectively, when placed next to each other, form a cup, across which an LED flip-chip can be placed. Each of the leads can be a respective electrode powering the LED flip-chip, which together with the symmetrical structure, provides a more even light emission profile and far-field pattern. A molded lens can be formed around the lead frame to protect the chip, as well as maintain a gap between the pair of leads of the lead frame structure. In some embodiments, a fill material can be added in the gap between the pair of leads.

  • Publication number: 20250132033
    Abstract: Example systems, methods, and apparatus are disclosed herein for dynamically assigning unique message identifiers for devices in a CAN bus network. The example systems, methods, and apparatus are configured to allow devices, such as infusion pumps, to propose and acquire unique IDs within a CAN bus network. The example systems, methods, and apparatus are configured to use the exchange of information between devices in a CAN bus network to prevent duplicate unique IDs, and to allow for simultaneous unique IDs to be acquired by devices. The disclosed systems, methods, and apparatus prevent human programming errors by minimizing the need for extensive user interaction with devices joining a CAN bus network and need to know and select node IDs during installation. The disclosed systems, methods, and apparatus increase network efficiency and prevent programming errors that might result in patient discomfort or injury in healthcare settings, such as networks including infusion pumps.

  • Publication number: 20250126941
    Abstract: Light-emitting diode (LED) packages, and more particularly arrangements of light-altering coatings in LED packages are disclosed. Exemplary LED packages may include lead frame structures that are at least partially encased by a housing. Arrangements of light-altering coatings may be provided that cover one or more portions of lead frame structures exposed within LED package recesses. By providing light-altering coatings that cover lead frame structures within package recesses, negative impacts from potential lead frame discoloration due to environmental exposure may be reduced. Additionally, such light-altering coatings may be configured to reflect light emissions from LED chips before reaching portions of lead frame structures. Light-altering coating arrangements are disclosed where light-altering coatings are arranged in contact with LED chips or, alternatively, in a spaced relationship with LED chips.

  • Publication number: 20250119285
    Abstract: Symmetric key exchange via TLS on CAN bus interface for multiple devices. The key exchange is configured to elect a master PCA pump for a CAN bus network and prevent two PCA pumps from being master. Upon joining the CAN bus network PCA pumps exchange their MAC IDs with the PCA pumps in the CAN bus network. Once a bootstrap timeout ends, each PCA pump compares all MAC IDs to determine if it should advance to the voting stage. If the PCA pump has the lowest MAC ID, the PCA pump enters the voting stage. During the voting stage, the PCA pump sends master requests prompts to all the PCA pumps in the network. If the PCA pump's internal vote counter reaches a count of three the PCA pump becomes key master.

  • Publication number: 20250089407
    Abstract: Light-emitting diode (LED) packages and more particularly LED packages that have LED chips mounted at different angles with respect to each to modify a far-field emission pattern are disclosed. The LED chips in the LED package can either be pitched inwards so that the light emissions from the LED chips generally overlap, or the LED chips can be pitched outwards. The LED chips can be mounted on a floor of a housing that has a plurality of angled surfaces. In other embodiments, the LED chips can be mounted on a platform in the housing that has different angled surfaces. In other embodiments, the LED chips can be mounted on one or more lead frame pins that can be angled, or angled with respect to other lead frame pins.

  • Publication number: 20250054920
    Abstract: Light-emitting diode (LED) packages and more particularly multiple chip LED packages with common electrodes are disclosed. LED packages include lead frame structures with a common electrode for multiple LED chips and other corresponding electrodes separately coupled to individual ones of the LED chips. The common electrode forms an anode or a cathode connection for each of the LED chips. The common electrode includes multiple extensions or pins that separately exit the package to provide separate external electrical connections to the common electrode. The common electrode may provide increased surface area of metal within the LED package to form an improved thermal body for heat dissipation. Multiple pin extensions from the common electrode allow LED packages to maintain a same form factor to be a drop in replacement for existing packages and allow enhanced adhesion with a housing that encases the lead frame structure.

  • Patent number: 12220599
    Abstract: Embodiments enables a wearable phototherapy apparatus that produces beneficial effects to a human body such as anti-viral effects, activation of stem cells, improvement in strength, improvement in stamina, pain relief via a non-transdermal container. May include an optional transdermal container that releases or increases copper peptide GHK-Cu in a subject's body. The non-transdermal apparatus reflects or emits specific wavelengths of light to elevate levels of the copper peptide GHK-Cu in the body. The non-transdermal apparatus includes one or more materials that prevent the Left-Handed molecule from direct contact with the body while the enclosure is coupled to the body and prevents the Left-Handed molecules from entering the body. Embodiments may include or be used with any bioavailable form of copper, e.g., such as copper glycinate as an anti-viral therapy and may include an anti-inflammatory or both.
