  • Patent number: 10184495
    Abstract: A portable air movement apparatus with improved air blending is provided, having a housing, an air generator, an air outlet, and an ambient air passageway through the housing of the device. The impeller and other components, such as the heating element, are disassociated from the location of the air outlet, allowing for the ability to use more than one air outlet, which serves to spread the air stream over a greater area. The disassociation of the impeller and other components from the air outlet also minimizes the housing size required near the air outlet, thereby allowing ambient air to be entrained in the air flow produced by the apparatus. As such, the apparatus moves more room air through the apparatus and more rapidly blends the air into the entire area or room.

  • Patent number: 10087889
    Abstract: A high-pressure fuel supply pump including an electromagnetically driven intake valve is configured such that a pressure equalizing hole is provided in the valve stopper positioned between the valve and a pressurizing chamber. The pressure equalization hole connects a spring storage space, provided between a valve and a valve stopper, with a surrounding fluid passage. The high-pressure fuel supply pump is further configured such that an opening of the pressure equalizing hole at the spring storage chamber side is open at a position at the inner side of a diameter of the spring. Since the pressure in the pressurizing chamber can be introduced into the inner side of the spring without traversing the spring, the unstable behavior of the spring or the valve due to the introduced pressure eliminated. Since the force applied to the valve when the valve closes is stabilized, the closing timing of the valve is stable.

  • Patent number: 10082144
    Abstract: The present invention describes methods to fabricate actuators that can be remotely controlled in an addressable manner, and methods to provide remote control such micro-actuators. The actuators are composites of two permanent magnet materials, one of which is has high coercivity, and the other of which switches magnetization direction by applied fields. By switching the second material's magnetization direction, the two magnets either work together or cancel each other, resulting in distinct “on” and “off” behavior of the devices. The device can be switched “on” or “off” remotely using a field pulse of short duration.
