Abstract: The invention provides a sensing device that can be incorporated in a construction element for a toy construction set to allow new use of construction elements, for instance tracking the construction process. Sensing device comprises a carrier comprising a top surface provided with a series of top coils, a bottom surface with a series of bottom coils at a distance from said top coils, the sensing device further comprising a data processor functionally coupled with a memory for storing a status, said data processor comprises a computer program which controls and reads currents through each of said top and bottom coils and storing them in memory, thereby tracking status for each of said top and bottom coils.

Abstract: A system having at least a first, a second and a third three-dimensional element, each element including a center point in the element, and a face with a motion-guiding module, coupled to the center point and defining a trajectory over the element, a motion module, adapted for displacing the center point with respect to a second center point of one of the other elements using the motion-guiding module of that other element, a motion-restriction module, adapted for limiting the displacement of the center point with respect to the second center point to at least one trajectory selected from the group which includes the trajectory and a second trajectory of the other element.

Abstract: A game, and a method for playing a game, that includes providing an initial shape of a plurality of elements, and an end shape that includes the elements by displacing, using a motion module for at least one element, which motion function provides the at least one element with its own movement ability relative to the other elements, in which the end shape is different than the initial shape; providing a set of parameters which together with the end shape determine losing or winning the game. The game is completed on a basis of the parameters and a position of the elements in relation to the end shape.

Abstract: An element having a holding mechanism, adapted for interacting with a functionally aligned holding mechanism of a similar element, and including a holding state and a released state. The holding mechanism in the holding state is engaged with the aligned holding mechanism of the similar element for holding the element positioned with respect to the similar element. The holding element in the released state is disengaged with the aligned holding mechanism. The element also includes a sensing mechanism for providing grab-detection, the grab-detection including detection of an action leading to a grip of the element, having a grip on the element, an action of releasing a grip of the element, and a combination thereof. The sensing mechanism is functionally coupled to the holding mechanism for upon the grab-detection actuating at least one of the functionally aligned holding mechanism between the holding state and the released state.

Abstract: A method for requesting digital content, in which repeatedly digital content is received within a trusted digital world of a user. The digital content is made available for a user to be experienced in his physical world. During the experiencing the content in his physical world, the user's interaction is recorded, and the recorded interaction is processed into a personal profile of the user. The personal profile is stored in the trusted digital world of the user, and at least part of the personal profile is transmitted under the authorization of the user from its trusted digital world to an untrusted digital world when requesting digital contents from that untrusted digital world.
