Abstract: A modular toy system comprising toy building elements including an arc toy building element. The arc toy building element has at least one knob receiving opening formed in a bottom surface or at least one knob formed in a top surface configured for coupling to complimentary coupling elements of another toy building element in a first direction. The arc toy building element also has an arc surface formed as a convex surface on the arc toy building element and extending over a length in a direction parallel to the top surface or to the bottom surface of the arc toy building element, the length is an integer multiple of a modular distance defining the spacing of a regular two-dimensional pattern for the toy building elements.

Abstract: An injection molding tool comprising two mold parts arranged for mutual movement along a tool axis between a closed position and an open position. The injection molding tool comprises a first mold core having a mounting end and a core end. Each of the two mold parts, in the closed position, form a mold cavity and a socket adapted for holding the mounting end between the two mold parts, and for releasing the mounting end in the open position. The core end of the first mold core in the closed position, extends along a core axis from the mounting end and into the mold cavity in a transverse direction with respect to the direction of the tool axis, so that the mold cavity forms a tubular space extending axially along the core axis between both of the two mold parts and the core end of the mold core part.

Abstract: A toy figurine comprising a multi-part housing. The toy figurine includes a circuit board provided in the multi-part housing. The circuit board is in electrical communication with an electrical switch for activating a functionality of the circuit board. The toy figurine includes an elongate pin provided in an interior of the multi-part housing and a push button provided on an exterior of the multi-part housing and adjacent to the elongate pin. Upon actuation of the push button by a user, the push button drives the elongate pin to contact the electrical switch.

Abstract: An interactive toy comprising a function device for performing user-perceptible, controllable functions. The interactive toy also includes a rechargeable power source and a charging circuit for contactless receipt of electrical energy and for charging the rechargeable power source when the interactive toy is positioned in a charging zone of a contactless charging device. The interactive toy is adapted to determine a charging rate at respective positions relative to the charging device and to generate a user-perceptible output indicative of the determined charging rate.

Abstract: An injection-molding tool comprising at least two separate mold parts arranged so that they can be moved along a central tool axis between a closed and an open position. At least one of the mold parts comprises an alignment compensator with a first and a second compensator part. The first compensator part has a socket adapted for receiving the second compensator part so that it can slide along the central tool axis in the socket, and for allowing the second compensator part to tilt in the socket. A seal is arranged so that the seal and the first and the second compensator part encloses a space in the socket containing an elastic or fluid material. The seal also comprises a lid made from a plastic material arranged between the second compensator part and the liquid filled space in the socket.

Abstract: A mold box for an injection molding machine, the mold box having a first mold plate, a second mold plate movably arranged relative to the first mold plate along a longitudinal axis, and a main guide rail system configured for guiding at least the second mold plate linearly away from and rectangular cross section perpendicular to the longitudinal axis. The main guide rail pillar extends through a third opening through a bearing arranged between the main guide rail pillar and the second mold plate. A guide track is formed as an elongate indention in a sidewall of the main guide rail pillar and has a first internal guide surface. A protruding bearing element extends from the third opening in the bearing and into the guide track.

Abstract: A computer-implemented method for creating an encoder-decoder system for embedding information in a decorative label. The method includes defining a family of encoder functions and a family of decoder functions. Each encoder function of the family of encoder functions configured to encode information as a respective modification of a decorative label. Each decoder function of the family of decoder functions configured to decode an image of a modified decorative label into respective decoded information. The method includes applying an iterative optimization process to determine an optimized encoder-decoder pair. The optimized encoder-decoder air includes an optimized encoder function and an optimized decoder function. The optimized encoder function is selected by the iterative optimization process from the family of encoder functions and the optimized decoder function is selected by the iterative optimization process from the family of decoder functions.

Abstract: A method for determining an assembly sequence of an assembling toy including a plurality of assembling elements disposed in a virtual space, Each of the assembling elements have at least one coupling part complementarily coupled to another coupling part, and connected to another assembling element through the coupling part, including a previously assembled element assembled to the assembling toy in the virtual space and a target assembling element that not yet assembled. The method for determining an assembly sequence includes: determining an assembly group in consideration of an upper surface height of the target assembling element connected to the previously assembled element, the upper surface height is calculated on the basis of a height from a ground to an upper surface of the target assembling element; and determining whether to generate a sub assembly group in consideration of the number of the assembling elements included in the assembly group.

Abstract: An alignment jig for holding and aligning a workpiece. The alignment jig has a base configured to support the workpiece and a first jaw extending from the base. The first jaw has a wedge-shaped flange defining opposing, angled alignment surfaces. The alignment jig also has a second jaw extending from the base of the alignment jig opposite the first jaw. The second jaw is moveable relative to the base such that the second jaw is configured to clamp a workpiece inserted between the first and second jaw against the alignment surfaces.
