Abstract: An electrically conductive holder is provided that is suitable for receiving a tablet electrode of a button battery. The holder includes a bottom portion to be fitted coaxially within terminal of a button battery. The holder further includes an upstanding wall portion. The bottom portion is flat and provided with a plurality of apertures through the complete thickness of the bottom portion. At least one group of apertures is distributed at regular angular intervals around the center of the bottom portion, spanning 360°. The strips of solid material of the bottom portion between two adjacent apertures are preferable narrow compared to the dimensions of the adjacent apertures so as to provide a mechanical support for the tablet electrode while also being able to deform under the influence of a volumetric expansion of the electrode.

Abstract: A battery-operated wristwatch includes a watch case, two strap parts and a clasp, wherein a battery housing including a battery is integrated in the clasp. One of the strap parts includes power transmission wires. The battery housing is coupled to the power transmission strap part by a first coupling that allows the transmission of a power signal. Likewise, the power transmission strap part is coupled to the watch case by a second coupling that allows the transmission of the power signal from the battery to the watch case. Particular embodiments are related to a watch provided with a deployable clasp comprising clasp portions which can be folded together, and wherein the battery housing is attached to one of the clasp portions.

Abstract: A support having two extensions which protrude forward on both sides in the final lower region, and an identical shoulder rest form a monolithic plastic hard shell. Vertically adjustable strips that support a waist belt are fixed to the extensions while a should mounting adjoins the shoulder rest via a ball-and-socket joint. The should mounting supports shoulder belt arrangements encompassing one respective top belt and a bottom belt which is joined to the top belt via a buckle, is pulled all the way to the extension through the buckle, and is anchored there. A bag for carrying material that is to be transported is disposed on the front face of the support, in the hard shell, the bag being accessible from the front, while straps for fastening a snowboard, showshoes, a helmet, or other large objects are mounted on the rear face thereof.

Abstract: An electric power tool (10) has at least one battery-powered electric motor, and the electric motor and the battery can be placed on the back of a user by means of a wearable unit (50). Via a flexible shaft (30), a driven tool (40) is driven by the electric motor. The wearable unit (50) has guide means (63 through 65), which engage the flexible shaft (30) in such a way that beginning at the back region of the user (52), this shaft is fixed in the shoulder region in such a way that it is secured against slipping off. This assures good guidance of the flexible shaft (30) and enables the user (52) to work ergonomically (FIG. 1).
