  • Patent number: 10318654
    Abstract: A method for slicing a three-dimensional model for printing of a corresponding object by a 3D printer, comprises: obtaining the envelope of the object as polygons, then for each region of a predefined work area within the slicing plane: identifying the closest polygon of said envelope that is positioned above said respective pixel; where no polygon is identified, then marking a corresponding region as a no-print region; if the direction vector of said closest above polygon has a positive component in the Z direction, then marking said corresponding region as a model region; and if the direction vector of said polygon has a negative component in the Z direction, then marking the region as a support region, and printing accordingly. An advantage of the above procedure is that the slicing, and in addition texture mapping, can be efficiently carried out on a graphics card or GPU.

  • Patent number: 10232583
    Abstract: A sparse micro-truss structure having a series of unit cells arranged in an array is disclosed. Each of the unit cells includes a series of struts interconnected at a node. Adjacent unit cells are spaced apart by a gap. Spacing apart the adjacent unit cells is configured to reduce the sensitivity of the sparse micro-truss structure to premature mechanical failure due to buckling in one or more of the struts compared to related art micro-truss structures having a series of fully interconnected unit cells.

  • Patent number: 10180363
    Abstract: The present application discloses a pressure detection structure and a terminal device. The pressure detection structure includes a cover, a display screen, a pressure sensor and a middle frame, the display screen and the cover being sequentially stacked in the middle frame from bottom to top; wherein: the pressure sensor is fixed to the display screen; the display screen includes a lower glass layer, an LED light emitting layer and an upper glass layer which are sequentially stacked from bottom to top; and the pressure sensor is positioned beneath the lower glass layer. Thus, the tolerance to be controlled mainly lies in the thickness of the gap layer inside the display screen, and the flatness of the pressure sensor. Hence, the assembling tolerance is reduced, and the stability, reliability and consistency of pressure detection by the terminal device are improved.

  • Patent number: 10043764
    Abstract: Aspects of the present invention generally relate to approaches for forming a semiconductor device such as a TSV device having a “buffer zone” or gap layer between the TSV and transistor(s). The gap layer is typically filled with a low stress, thin film fill material that controls stresses and crack formation on the devices. Further, the gap layer ensures a certain spatial distance between TSVs and transistors to reduce the adverse effects of temperature excursion.
