Abstract: The disclosure discloses a milk protein concentrate-based microencapsulation wall material and microcapsules, and belongs to the technical field of microcapsule preparation. In the disclosure, liquid or solid microcapsules are prepared by performing cation exchange treatment on milk protein concentrates, and then using the treated milk protein concentrates as a wall material. The prepared microcapsules have good physical and chemical stability during storage, and are suitable for protecting active functional factors and to be applied in the fields of food, medicine, health care products, cosmetics, daily chemicals and the like.

Abstract: A face mask includes an outer layer, an inner layer, and a filter. The outer layer includes an outer front guard constructed from a light-transmissive material and an outer filtering surface extending posteriorly from the outer front guard that includes at least one outer air hole. The inner layer is nestled within the outer layer. The inner layer includes an inner front guard constructed from a light-transmissive material and separated from the outer front guard by a buffer space. The inner layer also includes an inner filtering surface extending posteriorly from the inner front guard that includes at least one inner air hole. A filter is positioned between the outer filtering surface and the inner filtering surface and covers the at least one outer air hole and the at least one inner air hole.

Abstract: Our invention combines a disposable dual walls lampshade in a specific arrangement to create a space to accommodate the attracting, killing, holding and disposing of insects on a light device. It separates the catching space from the lighting area for keeping a clean lighting. The disposable dual walls lampshade comprises of an internal wall and an external wall, the two walls sealed in bottom edges and has a small open in the top, it forms a one workable piece. All insects will always be caught inside by applied sticky material or chemical agent, insect dead body is trapped in the space between inside of the external wall and outside of the internal wall. Since the dead insects always kept inside the cavity, there is no directly way to touch dead insect, it is safe for children and pets because the special arrangement of the double walls.

Abstract: The double side doors armored vehicle combines hinged side door with a foldable top screen and a foldable bottom panel, overlaid by a gullwing door in a vehicle body together in a specific arrangement to form a half-closed space for providing multiple direction shields to soldier and police when all of doors and panels are opened. The opening gullwing doors can protect attacks from high building. The opening swing doors can protect from front, right, and left. The standing up top screens and unfold bottom panels extend protection to soldier's head and legs. The vehicle provides multiple directions protection as a mobile shield that is stronger than personal protection devices. It can be a man driven car or an autonomous vehicle. It can be used as leading vehicle, or used in group for protecting marching soldiers. It can be a checking post, a block, an information collecting center.

Abstract: Our single disposable mini coffee tube comprising a porous tube, a rolled filter, a top, and a bottom to form a complete container that has multiple functions of holding, filtering, and stirring in a standing posture in a cup of water or a coffee machine during a brewing process of coffee or tea. The appearance of the coffee tube is as slender as a pen or cigar. This 3 in 1 coffee tube, filter, and mixing tool creates a rigid handle that allows user to stir a strong water circulation for extracting more essences and. A short and strong brewing not only extract more essences and aroma as Espresso, but also reduce bitter. This disposable coffee tube will be pre-filled with ground coffee or tea, and sealed by wrapping foil as a single packaging for a single fresh service.

Abstract: A bagged cooling stand for raising a laptop computer to increase air circulation comprises a sleeve, a pocket, a foldable cooling stand. The folded cooling stand is anchored inside of the pocket. The self contained cooling stand comprises a frame, leaves, and pins. There are 2 opposite slopes in the ribs reinforced flat frame for locking the leaves on standing up position with gravity of a laptop. The cooling stand has flat shape and similar outside profile of the pocket for storing and portable, and is strong enough as a portable desk. After opening the pocket and setting up the leaves of the stand on user's lap, a laptop can seats on lifted edges of the leaves for free air flowing and lowering temperature of the laptop. Lower temperature will increase the performance of a laptop and make user operate on his lap comfortably.

Abstract: A transparent foldable dust bag is designed as an attachment for a vacuum cleaner and like. The transparent foldable dust bag has a foldable outer transparent wall portion and a foldable inner filter cone portion connected by the top connector and the bottom flange to form a hollow cavity for separating and collecting dirt and dust from air. Opened dust bag is deployed and stretched by the rigid top connector and bottom flange for keeping the shape of the dust bag in a designed position. See through the outer transparent wall of the dust bag allows to look filling level inside of the dust bag and to replace it properly without exposing collected dust and dirt.
