Patent number: 12241795Abstract: A thermally luminescent temperature sensor with a rare earth emitter having a first selective electromagnetic light energy emission band and a second selective electromagnetic light energy emission band in which the rare earth emitter converts thermal energy to electromagnetic light energy within the first and second selective energy emission bands. The sensor also has a selective optical detector in optical communication with the rare earth emitter, wherein the selective optical detector independently detects each the first and second selective electromagnetic light energy emission bands. Lastly, the thermally luminescent temperature sensor determines the temperature based on the electromagnetic light energy measured within the first and second selective energy emission bands relative to each other. Optionally additional emission bands may be used in the evaluation of the temperature.Type: GrantFiled: July 19, 2019Date of Patent: March 4, 2025Assignee: TDA Research, Inc.Inventors: John M Alford, David P Eisenberg, Girish Srinivas

Patent number: 12220497Abstract: A method for decontaminating the outer integument of an animal without transferring contamination to the inner integument of the animal where the hazard can interact with the skin and harm the animal further. The animal has either fur, hair, or feathers and the inner integument is the skin and a skin-hazard material is present on the outer integument (the fur, hair, or feathers). The method uses a first porous dry wipe to sequester the skin-hazard material away from the contaminated animal by either wiping, blotting or rubbing the outer integument of the contaminated animal. The method avoids using free-flowing liquid in contact with the inner integument of the contaminated animal, and does not promote a liquid-phase transfer of the skin-hazard material from the outer integument to the inner integument.Type: GrantFiled: July 26, 2021Date of Patent: February 11, 2025Assignee: TDA Research, Inc.Inventor: Christopher Brian France
