Abstract: A vacuum attachment for a vacuum tube of a vacuum for a non-destructive screening of an object and/or a living creature. The vacuum attachment includes a suction tube, a collection unit, and an adapter unit. The suction tube has a first end and a second end. The first end is arranged opposite to the second end. A suction opening is arranged at the first end. The collection unit for the non-destructive screening is arranged in the suction tube downstream of the suction opening in a suction direction. The collection unit has at least one opening for a flow of a suction air stream, and an air-permeable impact protection material arranged upstream of the at least one opening in the suction direction. The adapter unit is arranged at the second end of the suction tube. The adapter unit connects to the vacuum tube of the vacuum.

Abstract: A training device for carrying out a muscle training for a person's muscle. The training device includes a control unit having a signal unit, a main body, and a load measuring device arranged on the main body. The person's muscle contacts the load measuring device in use. The load measuring device has a load sensor which determines a load exerted by the person on the load measuring device at a measuring point which is correlated with a partial region of the muscle at a measuring point position. The control unit outputs a contraction signal to the person via the signal unit so that the person performs a signaled muscle contraction based thereon. A successful performance of the signaled muscle contraction is verifiable by comparing a load profile, which is determined by the load measuring device, with a comparison load profile.

Abstract: A game set includes a first, a second and/or a further edge element, and a connection element with a first receptacle to receive the first edge element, and a second receptacle to receive the second and/or the further edge element. The first edge element and the second and/or further edge elements are detachably connected via the connection element. The first, the second and/or the further edge element, when connected, together form an edge for deflecting a movement of a movable game element for a playing area onto a playing area plane. The first, the second and/or the further edge element has/have a main body which has a curved cross-section having a curvature contour. The main body can thereby have a rolled-up or a stretched position. The main body is receivable, in the stretched position, with the curvature contour along a respective receiving axis in the first and/or second receptacle.

Abstract: A device for setting up a game with a ball, the device being reversibly dismountable so that it can be assembled and/or played with anywhere on an existing plate surface. The device includes at least one ball clamping unit with a first side wall, a second side wall, and a ball admission opening which is arranged between the first side wall and the second side wall. The ball is clamped in the at least one ball clamping unit so that the ball remains on the existing plate surface when the ball enters the ball admission opening. The at least one ball clamping unit is detachably fastened to the existing plate surface in an assembled state.
