Abstract: A battery charging apparatus includes a battery compartment having a receptacle that is configured to receive a battery pack. The battery charging apparatus includes a first heat exchange module and/or a second heat exchange module. The first heat exchange module includes a plenum surrounding the receptacle, where the plenum includes a chamber to receive a fluid. The plenum also includes a plurality of flow guides disposed in the chamber to define a variable flow passage for the fluid. The second heat exchange module includes a battery connector and a heat sink thermally coupled to the battery connector. The heat sink is arranged to dissipate thermal energy from the battery pack.

Abstract: A process of manufacturing a loops component of hook-and-loop fastener include placing a thermoplastic material in a dehumidifier to remove water from the thermoplastic material; mixing the dry thermoplastic material in a mixing device to form a liquid substance; activating the membrane making device to make a continuous membrane; activating a laminating device to heat the continuous membrane on a fabric to form a loops component by sticking the continuous membrane and the fabric together; placing the loops component in a cooling device to form a solid loops component; activating a cutting device to cut the solid loops component into first loops components; activating a heating device to join left and right sides of the first loops component to form a second loops component having an outer fabric and an inner membrane; and activating the cutting device to cut the second loops component into finished loops components.

Abstract: A seamless kneepad structure is composed of a sheath, adjusting bands, and support pieces, wherein the sheath is in a shape of a sleeve made by an elastic fabric, a protection part is located at a front face of an exterior surface of the sheath, and a plurality of connection parts and stick parts for fixing the adjusting bands are located two sides of the sheath respectively. An extension hole is located at an opposite surface of the protection part, the adjusting band is constituted by a main body, a fixing piece, and an adjusting piece, and the support piece is made by connecting two iron pieces to a connection part whose back surface is provided with a stick piece.

Abstract: A method of manufacturing waterproof, highly absorbent, and highly flexible fabric comprises drying TPU material or thermoplastic elastomer at about 50° C. to 150° C. for about predetermined hours, adding a bridge agent in the dried TPU material or thermoplastic elastomer for mixing and heating at about 60° C. to 280° C. for about 30 seconds to 5 minutes for melting, pouring the melted material into an endless shallow mold to form a continuous film, contracting a fabric material at about 50° C. to 180° C. for about 1 second to 5 minutes, placing the fabric material onto top and bottom surfaces of the film and pressing same at about 50° C. to 250° C. to form a composite fabric, cooling and shaping the composite fabric at about 5° C. to 60° C., and drawing the shaped composite fabric around a roll to produce the finished composite fabric.

Abstract: An anti-theft combination lock for car includes a main body having a transverse hole, a driving unit located at one side of the main body, a lock rod extended through the transverse hole of the main body, a lock plate fixedly connected at an end to a power output shaft of the driving unit to movably locate at an upper outer side of the transverse hole to normally engage with one of many annular retaining grooves on the lock rod to set the lock in a locked state. A password may be entered via an input interface provided on a top of an outer case of the main body. An internal memory processor determines the correctness of the entered password and actuates the driving unit to turn the lock plate to an unlock position when the entered password is correct.
