Abstract: A backpack with multiple connected airbags includes a backpack body, a first airbag unit, and at least an air inlet. The backpack body has a set of straps. The first airbag unit includes a plurality of first airbags and is connected to the rear side of the backpack body. A groove and an air channel are formed between each two adjacent first airbags. The air channels allow the air in the first airbags to flow between the first airbags. The first airbags are so arranged that each first airbag in the peripheral region of the first airbag unit occupies a larger area on the rear side of the backpack body than any first airbag in the central region. The air inlet is in communication with at least one first airbag. The backpack can lie compliantly against the user's back to provide enhanced comfort and stability while protecting the user's spine.

Abstract: A paper wallet with a wireless device has a wallet body and a wireless device. The wallet body is made of a paper template folded to form multiple pockets. The wireless device is securely mounted on the paper template and received in one of the pockets of the wallet body. Since the wireless device is preliminarily fixed on the paper template, the wireless device is free of damage caused when the paper template is being folded. Additionally, as electromagnetic wave can easily penetrate the paper wallet, the wireless device inside the paper wallet can be easily detected.

Abstract: A foldable cardboard template has an outer panel, multiple binding strips respectively formed on and protruding from one of the two longitudinal sides and two transverse sides of the outer panel, and an interlayer board formed on and transversely protruding from the other longitudinal side of the outer panel having no binding strip formed thereon. The interlayer board is ladder-like and has multiple interlayers connected with each other, multiple partition lines and multiple card slits formed therethrough. Each partition line is formed between two adjacent interlayers. The interlayer board is folded at the partition lines to lean toward the outer panel and form multiple pockets between the interlayers. The binding strips are affixed to the folded interlayer board to fix the outer panel and the interlayer board together. The folded interlayer board and the outer panel are folded at a center fold line to make a paper wallet.
