Abstract: A stimulation device and a method to coordinately stimulate two separate nerves in a human or animal body for activating a target tissue in the human or animal body comprises a first coil unit (91) configured to be positioned at the human or animal body to stimulate a first nerve of the two separate nerves, a second coil unit (92) configured to be positioned at the human or animal body to stimulate a second nerve of the two separate nerves; and a bracket structure (93) coupled to the first coil unit (91) and the second coil unit (92). The bracket structure (93) is adjustable such that positions and orientations of the first coil unit (91) and of the second coil unit (92) relative to each other are adaptable to a target configuration in which the first coil unit (91) and the second coil unit (92) are distinctly positioned at the human or animal body such that the first nerve can be stimulated by the first coil unit (91) and the second nerve can be stimulated by the second coil unit (93).

Abstract: A bearing adapter for a disk-shaped accessory tool which has two sides. The bearing adapter includes a bearing unit configured to reduce a bearing recess of the accessory tool. The bearing unit is configured to adjoin the accessory tool and to enclose a portion of the accessory tool on the two sides when the bearing unit is mounted on the accessory tool.

Abstract: A bearing device of a portable power tool, in particular a router, has at least one main body unit. The main body unit is formed as a corner guiding unit and has a bearing surface and a lead-through opening. The bearing surface is configured to bear on a workpiece. The lead-through opening is configured to receive an insert tool configured to perform work on a workpiece.

Abstract: A spindle locking device for a portable machine tool includes a locking unit and a movement activation unit. The locking unit has a movably mounted locking element configured to lock a spindle of the portable machine tool in at least one direction, and an operating element configured to actuate the locking element. The movement activation unit is configured to pretension the locking element in a direction towards a locking position, at least when the operating element is in an unactuated position.

Abstract: A portable machine tool switching unit includes a turning knob unit, which has a coupling unit that can be rotatably driven for coupling to at least one switching element, and further includes at least one energy storage element provided for storing switching energy in the case of a preselection. The energy storage element is integrated in the turning knob unit.

Abstract: A portable power tool includes at least one drive unit configured to drive an insert tool, at least one housing unit in which the drive unit is disposed, and at least one marking unit configured to mark a relative position of a drive axis of the drive unit on a workpiece to be machined. The the marking unit is disposed on the housing unit.

Abstract: A portable power tool includes at least one seating unit configured to seat on a workpiece, at least one housing unit mounted so as to be movable relative to the seating unit, and at least one movement delimitation unit that has at least one movement delimitation element configured to set a length of a movement travel of the housing unit relative to the seating unit. The portable power tool further includes at least one decoupling unit configured, in at least one operating state, to decouple the movement delimitation unit from a movement of the housing unit when the movement delimitation element is in a fixed state. The decoupling of the movement delimination unit occurring at least in the case of a movement of the housing unit in the direction of the seating unit.
