  • Publication number: 20240144844
    Abstract: Systems and methods are disclosed for an apparatus and method for practicing injection techniques through an injectable apparatus. The injectable apparatus may contain a camera that is configured to detect the intensity and color of light attenuated from a testing tool after it is injected into a simulated human or animal body parts. A training tool may be connected to a user display device to generate a display of the injection apparatus as well as the performance parameters of a trainee.

  • Patent number: 8567709
    Abstract: A twin-rotor side-by-side compound rotorcraft has a fuselage and variable incident wing assembly that pivots relative to fuselage. The aircraft also has landing gear assembly and a tail fin assembly. The variable incident wing assembly is pivotally attached to the fuselage, and includes wing members, engines fixedly mounted to the wing members or another area of the rotorcraft, and a mast attached at a fixed angle relative to the wing members. Then engines may also be located near the fuselage or another area of the rotorcraft. The variable incident wing assembly is capable of pivoting about a pivot axis, thereby allowing mast orientation in at least a hover mast position and a forward flight mast position. The rotors provide additional forward thrust and the wings provide additional lift, when the mast is in the forward flight mast position.
