Abstract: An approach for facilitating mechanical and electrical connection of electric machines and electrical components in an electrical system using connectors with quick connect/disconnect electrical connectors is disclosed. Each quick connect/disconnect electrical connector can be placed on the end of an electrical power distribution cable that connects with an electric machine or electrical component. The electric machines and electrical components and the electrical power distribution cables can have hollow coolant passages formed therein to receive cooling fluid from a cooling device for direct cooling of the electric machines, electrical components and the electrical power distribution cables.

Abstract: The invention is a device and corresponding method for the rotatable selection, preparation and recollection of hemodialysis cannulation sites along a surgically constructed arterio-venous fistula or arterio-venous graft of a patient with end-stage renal disease. The device comprises a program, a site preparation card, transparent dressings held in a dressing folder; transferably detachable self-adhesive mnemonic markers, and a skin marking device. The program has means for removably receiving the site preparation card, the transparent dressings held in the dressing folder, and the detachable self-adhesive mnemonic marker. The skin marking device has means for removably attaching to the program.
