  • Publication number: 20250387640
    Abstract: A cancer treatment with improved effectiveness may feature emission of radiant energy from a laser source based upon measured parameters, particularly melanin content, in a patient's surrounding tissues. Multiple wavelengths of radiant energy, pulse durations, and intensities may be utilized in the radiant energy emission based upon the patient's tissue parameters. One embodiment of a laser source features multiple laser modules (201) which may be independently operated and adjusted for intensity and active duration.

  • Patent number: 12246105
    Abstract: An UV disinfection system (200) may feature a chamber (207) with internal spherical reflective surfaces (208) to evenly reflect UV radiation from all angles to direct the UV radiation to all surface area of the object inside the chamber to disinfect object utilizing UV radiation under controlled time. An object (215) to be disinfected may reside within the chamber (207) on a UV transparent rack or shelf (214). The spherical reflective surfaces may be fashioned by placing such surfaces on a polyhedral internal structure or making the internal chamber spherical in and of itself (208). Multiple UV sources (209a), (209b) may also be utilized.

  • Publication number: 20250013063
    Abstract: By using techniques to diverge an emitted beam, the same base device may be utilized as either a cutting laser or a curing light. The use of multiple frequency laser modules (312) and a selection of emitter heads (304) allow for systems (300) which may be used for a wide variety of medical and dental procedures. Each system (300) has a plurality of emitter heads (304) to select from either a curing light, a cutting laser, or any other therapeutic energy emission all while utilizing the same laser module (312). Various structures of emitter heads are disclosed, as well as laser modules and connection strategies.
