Abstract: The present invention relates generally to interlocking spatial components, and more particularly to spatial components having mating surfaces of uniform periodical structure comprising a regular array of interlocking connectors of the same shape allowing components to be arbitrarily interlocked along various relative directions, in various relative orientations, and upon various sides and to be assembled with one another to create spatial structures.

Abstract: A data entry system comprising of: an input surface, a limited number of input elements of any shape and positions at the input surface, and a processing device (for detecting a continuous sweeps of an input object over the input surface, for tracking a sequence of the input elements interacted with the input object during such sweeps, and for generating a function associated with the sequence after the sweep is completed). A system characterized in that the processing device is adapted for time independent and reliable detecting a sequence of input elements, even if an input object could interact with several input elements simultaneously. A system also characterized in that the sweeps may represent strokes of handwritten symbols. The invention can be utilized in new designs of compact data input systems for electronic devices.
