Abstract: A method, and devices for facilitating the method, for shoulder replacement surgery. The method entails establishing a mechanical support in a the anatomical neck plane of the proximal humeral head, fixing a jig to the mechanical support, where the jig supports a drill guide with its axis perpendicular to the anatomical neck plane, adjusting the drill guide it coincide with the axis of the humeral head, drilling a hole through the humeral head for insertion of a shaft which will support and rotate a reaming bit. The reaming bits used to resurface the humeral head and the glenoid fossa are inserted through the back of the patient, through a gap created between two easily separated muscles, rather than through a gap cut through the subscapularis muscle on the front of the joint. A suitable jig is provided to facilitate the method.

Abstract: A reversible garment comprises first and second surfaces, each of which are capable of forming an outer surface of the garment when worn in reversible configurations. The first surface is generally ordinary in appearance while the second surface is highly visible. The reversible garment is preferably a bicycle jacket. The second surface may at least partially comprise a material that is reflective, bright in color, or luminescent. The second surface may be comprised of an elastic material to make the garment close-fitting in a high-visibility configuration.

Abstract: A method for automatically commencing a conference call includes a computer that is connected to a telephone network. The computer automatically calls telephone numbers of conferees at a scheduled time and date and conferences together the conferees who answer their telephones. The telephone numbers and the time and date of the scheduled conference call are inputted to the computer prior to the conference call. The computer may connect conferees to one another automatically as soon as the conferees answer their telephones. Optionally, the computer may connect the conferees to one another only after the conferees choose to be connected.
