Abstract: A smart respirator includes a main respirator-body including a first open end and a second open end. A diameter of the first open end is smaller than a diameter of the second open end. The smart respirator further includes a front respirator-body arranged at the first open end. The front respirator-body includes a filter sheet arranged inside the front respirator-body and configured to absorb pollutants in air entering the front respirator-body, an air sensor arranged inside the front respirator-body and configured to detect an air index of filtered air filtered by the filter sheet, and a flow sensor arranged inside the front respirator-body and configured to determine a total respiratory amount. The smart respirator also includes a fixation band arranged at the second open end.

Abstract: A smart mask includes a main mask body including a first opening end and a second opening end. A diameter of the first opening end is smaller than a diameter of the second opening end. The mask further includes a front mask body arranged at the first opening end and fixing straps arranged at the second opening end. The front mask body includes a filter configured to absorb pollutants in air entering the front mask body and a sensor configured to record a wearing time of the smart mask.

Abstract: Machine logic (for example, software) for determining a placement mode of at least one kind of objects in a multiplicity of storage areas are disclosed. A placement method includes the following operations: determining attraction factors of the multiplicity of storage areas, an attraction factor of each storage area indicating a capability that the storage area attracts attention of a customer; determining a spatial elasticity factor of the at least one kind of objects, a spatial elasticity factor of each kind of objects indicating an impact of a change of the storage areas where the kind of objects are placed on an attention degree of the kind of objects; and determining the placement mode of the objects in the multiplicity of storage areas, at least according to the attraction factors of the multiplicity of storage areas and the spatial elasticity factor of the at least one kind of objects.

Abstract: The present disclosure relates to a universal wheel assembly and a suitcase including the universal wheel assembly. The universal wheel assembly includes: a base structure including an upper base and a lower base which form a cavity therebetween; and a wheel bail locked in the cavity in a manner such that the wheel ball is capable of rolling in all directions, wherein a bottom of the lower base is provided with an opening enabling a part of the wheel bail to protrude out of a lower end face of the lower base to form an exposed rolling spherical surface, and an inner diameter of the opening is smaller than a diameter of the wheel ball.

Abstract: A chargeable case of an electronic device includes an envelop body for enveloping an electronic device therein, a receiving coil, a power output interface and a built-in AC/DC rectifying circuit. The receiving coil wirelessly receives alternating current from a power supply device. The power output interface connects a power input interface of the electronic device. The AC/DC rectifying circuit is connected the receiving coil and the power output interface. The AC/DC rectifying circuit converts the received alternating current into direct current and supplies the direct current to the power output interface for charging the electronic device. A charging system is also disclosed.

Abstract: The present invention provides an antigen-presenting cell(APC)/tumor cell conjugate, wherein the antigen-presenting cell (APC) is modified by a cytokine gene selected from the group consisting of IL-2, IL-3, IL-4, IL-6, IL-12, IL-18, IFN?, IFN?, IFN?, TNF, TGF, GM-CSE, and the combination thereof. The conjugate is useful as a tumor vaccine to significantly induce an immunity specifically against the tumor cell The present invention also provides the method for preparing the conjugate and a pharmaceutical composition containing said conjugate.
