Abstract: The invention relates to a device for supplying electrical energy to an electro-pen with an electric drive unit for driving a tool. The device comprises a console with an energy supply unit having an accumulator for supplying the electrical drive unit with electrical energy. The console may be configure to be sterilized by steam having a housing and electrical components that are sealed liquid-tight. The accumulator may include a sterile covering for sterile introduction into the console. A coupling between the console and the electro-pen carries the supply of electrical energy from the console to the electro-pen. The coupling may be an electrical contact in the form of a sterilizable connector or an inductive coupling. The console may be configured to store energy and is thus mobile, or the console may include a connection for connecting to a mains or external power supply for charging the accumulator. The console may include a switch-mode power supply for charging the accumulator.

Abstract: Date mechanism for a timepiece such as a wristwatch including two superposed respectively lower (6) and upper (4) date rings, whose surface is divided into a plurality of sectors, the upper ring (4) including sixteen sectors, fifteen of which respectively bear fifteen successive markings of a cycle of 31 positions, and the sixteenth of which is an extra sector having an open or transparent aperture (8), whereas the lower ring (6) includes seventeen sectors, sixteen of which bear respectively the other sixteen markings of the cycle of 31 positions, and the seventeenth of which is an extra sector, each of said rings cooperating with drive means such that the markings appear successively in a display zone (20) the date mechanism further including a jumper-effect stopping device (22) able to stop each ring (4, 6) in any desired position, the date mechanism being characterised in that one location on the upper ring (4) and one location on the lower ring (6) is provided with a thinned tooth (14) and (16), located b
