Abstract: The invention relates to a teaching device (1) for electronic piano. The teaching device (1) comprises a processing unit (2) and a light-emitting strip (3). The processing unit (2) comprises a casing (11?) housing an electronic control module (12) configured to be driven by a remote peripheral terminal. The light-emitting strip (3) is flexible and is removably connected to the processing unit (2) by cabling (6), the light-emitting strip (3) being configured to visually guide to at least one note to be played when said light-emitting strip (3) is mounted on a keyboard of the electronic piano.

Abstract: A system for and method of reconstituting post mortem circulation is provided. Certain methods include simulating natural clotting cascades at wound sites while preventing clotting in reservoirs and within the cadaver. Clot prevention in the reservoir and the cadaver are accomplished with an anticoagulant and a dispersant, respectively. Simulation of clotting at the wound site is accomplished by diluting cadaver fluid with reservoir fluid, thereby diluting the dispersant. The cadaver fluid contains excess calcium for resisting the anticoagulant of the reservoir fluid. Certain methods of the present invention also include reanimating a heart, attaching foreign cadaveric circulatory branches to other cadaveric tissue, enabling mobile cadaveric perfusion, and utilizing a water bath with gravity-feed perfusion.
