  • Grain refining with direct vibrational coupling
    Patent number: 11998975
    Abstract: A molten metal conveyor having a receptor plate in contact with molten metal during transport of the molten metal. The receptor plate extends from an entrance where molten metal enters onto the receptor plate to an exit where molten metal exits the receptor plate. The molten metal conveyor has at least one vibrational energy source which supplies vibrational energy directly to the receptor plate in contact with molten metal. A corresponding method for forming a metal product includes providing molten metal onto a molten conveyor; cooling the molten metal by control of a cooling medium flowing through a cooling passage in the or attached to the conveyor; and coupling vibrational energy directly into a receptor plate in contact with the molten metal on the conveyor.

  • Multi-segment monolithic LED chip
    Patent number: 12002915
    Abstract: LED chips comprising pluralities of active regions on the same submount are provided. These active regions are individually addressable, such that beams output from the LEDs can be controlled simply by selectively activating the desired active region in the plurality without requiring advanced optics and reflectors comprising complex moving parts. In some embodiments, one or more active regions can surround one or more other active regions. In some embodiments, the various active regions are individually addressable by virtue of each active region comprising its own anode and sharing a common cathode. In some embodiments, the various active regions are individually addressable by virtue of each active region comprising its own cathode and sharing a common anode. In some embodiments, each active region comprises its own anode and its own cathode.

  • Reflectometry instrument and method for measuring macular pigment
    Patent number: 11998276
    Abstract: A reflectometry instrument includes a light source for emitting an illumination beam that illuminates the macula. A portion of the illumination beam is reflected from the macula and forms a detection beam. The detection beam is indicative of macular pigment in the macula. The instrument also includes a first mirror for reflecting the illumination beam toward the macula and for reflecting the detection beam from the macula. The instrument is configured so that the illumination beam and the detection beam remain separated between the macula and the first mirror.

  • Racquet pick up scoop for balls
    Patent number: 11998807
    Abstract: A ball pick-up scoop can be attached to, or molded on, the head end of a tennis racquet. When mounted, formed, or attached the scoop protrudes roughly 80°-90° away from the face side of the racquet. While standing up straight and holding the handle of the racquet, the user slides/pivots the scoop under a ball (tennis, rubber, synthetic, etc.), which cradles the ball between the scoop's ball guides and the racquet's face to facilitate picking up the ball without ever bending over. Once the ball is cradled the user can pivot the racquet up to their opposite hand and grab the ball, or flip the ball up and hit the ball, or let it bounce and then hit the ball.

  • System for monitoring backflow preventer condition
    Patent number: 12000123
    Abstract: A backflow preventer including a body having an inlet for connection to an upstream portion of a plumbing system and an outlet for connection to a downstream portion of the plumbing system, a first check valve and a second check valve located in the body for preventing the reverse flow of water between the outlet and the inlet. An inlet pressure zone is positioned between the inlet and the first check valve, an outlet pressure zone is positioned between the outlet and the second check valve, and an intermediate pressure zone is positioned between the first and the second check valves. Position sensors sense the positions of the check valves, and pressure sensors sense the pressures in the zone. A controller in communication with the position sensors and the pressure sensors calculates the opening and closing pressures of the check valves.
