  • Patent number: 11844544
    Abstract: A device for use with a debridement system is disclosed. The device includes an outer tubular shaft having an inner surface defining a lumen along an axis, the inner surface having an inner surface diameter. An inner tubular shaft is disposed within the lumen and rotatable within the outer tubular shaft. The inner tubular shaft includes an outer surface having an outer surface diameter less than the inner surface diameter. The inner surface of the outer tubular shaft with the outer surface of the inner tubular shaft forms a channel along the axis to receive fluid from the fluid source. The rotor is disposed in the channel and includes an axially extending helicoid blade coupled to the inner tubular shaft. The blade rotates within and with respect to the outer tubular shaft and exerts an axial thrust on the fluid in the channel with respect to the outer tubular shaft.

  • Publication number: 20230385563
    Abstract: The present invention relates generally to a smart tool board device that stores at least one tool and ensures said tool is not lost or misplaced during use. At least one RFID reader on the board detects at least one RFID element that is attached to each tool such that the RFID reader can detect when a tool has not been placed back onto the tool board. Once this occurs, the device may communicate to a manufacturing line and/or process to cease the operation of the manufacturing process.

  • Patent number: 4012807
    Abstract: A hinge for the rear end of a hood that selectively closes a vehicle body forward engine compartment opening, including interconnected body and hood hinge members movable into an interreceived relationship for the hood closed position, and a locking pawl pivotally mounted on the body hinge member such that forced rearward movement of the hood hinge member causes the locking pawl to pivot so as to engage an aperture formed in the hood hinge member, serving to diminish vertical and rearward movement of the hood during impact conditions and upon relaxation of the impact loads.
