  • Patent number: 9737802
    Abstract: The present invention discloses a system and method for recognizing objects placed together using capacitance sensors in conjunction with the RFID technology. A structure that is made with a material of high dielectric constant and a RFID tag that comprises a unique identification code (UID) of an object is embedded with the object. With the objects recognized, the spatial structure or the spatial distribution formed by them is derived and corresponding sensory feedbacks are provided by the system.

  • Publication number: 20160310862
    Abstract: The present invention provides a system and method for construction of a spatial structure through the use of short-distance wireless communication means such as the infrared diode or pulse modulation. The system includes a plurality of objects, each object comprising multiple emitters and multiple receivers, each embedded near a surface of an object. Once a signal comprising information stored in multiple objects is received by the receiver of a particular object, a microprocessor is configured to derive the spatial relationship of these multiple objects relative to the particular object, and direct the information to be stored in its data storage means. A central processor receives information regarding the plurality of objects and derives a spatial structure formed by the plurality of objects. The present invention is useful in a variety of fields that require construction of a spatial structure. Example areas of applications are education, entertainment and productivity enhancement.

  • Patent number: 9144783
    Abstract: A low pressure drop structured packing sheet with diversion windows, which are formed on both crests and troughs. When in the expanded state where the diversion window and packing sheet are flat on the same plane, the diversion window has an opening and a fan-shaped portion, with the area of the opening being 0%-1000% of that of the fan-shaped portion. Two side intersection lines between the fan-shaped portion and packing sheet is symmetrical with respect to a central folding line which divides the fan-shaped portion into a left part and a right part. The two side intersection lines intercept to each other with an angel of about 10°-170°. When in the operating state where the diversion window and packing sheet are partially folded towards opposite directions, the fluid at the trough flows to a crest of the other side of the packing sheet with the help of diversion windows, thus increasing the area of vapor-liquid mass transfer.
