Patent number: 11111145Abstract: A method for modifying a fine particle dispersion liquid with which dispersibility and dispersion stability can be improved includes performing filtration to remove impurities in a dispersion liquid using a dispersion liquid modifying device provided with a removal unit that uses a filtration membrane. The quantity of impurities is reduced from a first region until said quantity reaches a second pH-dependent region. In the second pH-dependent region, the dispersibility of the fine particles in the dispersion liquid is in a range in which the dispersibility depends more on a change in dispersion liquid pH than on a change in the quantity of impurities in the dispersion liquid. With the quantity of impurities reduced to the second pH-dependent region, the dispersibility of the fine particles is controlled by adjusting the pH of the fine particle dispersion liquid.Type: GrantFiled: February 1, 2017Date of Patent: September 7, 2021Assignee: M.

Patent number: 11058601Abstract: This application discloses systems and methods of applying vibration to a targeted area on an individual that is experiencing pain, discomfort, or other musculoskeletal symptoms. Steps of the method include lengthening followed by oscillation and vibration. The lengthening step requires positioning the individual (e.g., with the help of a stretching cage) such that the individual experiences a stretching sensation in a targeted area (e.g., a group of muscles, ligaments, tendons, etc.). Next, the individual oscillates in and out of that lengthened position while vibration is applied to the targeted area. It has been discovered that these techniques can bring about dramatic and quick improvements in flexibility and range of motion, while also diminishing symptoms like pain and discomfort.Type: GrantFiled: June 10, 2019Date of Patent: July 13, 2021Assignee: Vibration Release Techniques LLCInventor: Matthew Christopher Gloyd
