  • Patent number: 12097603
    Abstract: An oscillating power tool has a housing including a handle portion defining a handle axis and a head portion defining an output axis that is perpendicular to the handle axis. The head portion includes a front face intersected by the handle axis. A drive mechanism includes an output shaft configured to oscillate about the output axis in a rotational manner in response receiving torque from a motor. A lighting assembly is configured to illuminate a workpiece in front of the head portion of the housing. The lighting assembly includes a lens arranged on the front face of the housing, a holder coupled to the lens, a plurality of printed circuit boards supported by the holder, and an LED arranged on each of the printed circuit boards. In response to being activated, the LEDs are configured to project a wide-angle beam of light through the lens.

  • Patent number: 12083599
    Abstract: The nozzles of a MHD liquid metal ejector/printhead can be clogged by contaminants in the liquid metal. Typically, these contaminants are in the form of small particles of aggregates of particles, such as metal oxides, that are insoluble in the liquid metal. Possible cleaning methods include mechanically removing the clogging material, such as by using a physical device to dislodge the clogging material and remove it; chemically removing the clogging material, such as by using selected chemicals/flux to chemically react with the clogging material; using ultrasound to break/remove the clogging material; and providing reversed and/or oscillating flow of material through the nozzle.

  • Publication number: 20200166440
    Abstract: An embodiment of the invention relates to a device for detecting an analyte in a sample. The device comprises a fluidic network and an integrated circuitry component. The fluidic network comprises a sample zone, a cleaning zone and a detection zone. The fluidic network contains a magnetic particle and/or a signal particle. A sample containing an analyte is introduced, and the analyte interacts with the magnetic particle and/or the signal particle through affinity agents. A microcoil array or a mechanically movable permanent magnet is functionally coupled to the fluidic network, which are activatable to generate a magnetic field within a portion of the fluidic network, and move the magnetic particle from the sample zone to the detection zone. A detection element is present which detects optical or electrical signals from the signal particle, thus indicating the presence of the analyte.
