Abstract: A flying air purifier includes a flying unit configured to fly within a space at a first elevation. The flying unit is also configured to fly within the space at a second elevation. The flying air purifier also includes an air purifier mounted to the flying unit and configured to remove particles from air within the space at the first elevation and at the second elevation. The air purifier includes an air inlet having a first charge and an air outlet having a second charge, wherein the second charge is opposite of the first charge.

Abstract: Devices and methods for converting movement into electrical energy. The electrical energy produced by the device can, for example, be stored in a storage device and used to power an electrical appliance. By using the devices, it is possible to provide a portable electrical device with a stable power supply that does not need to be recharged.

Abstract: Methods and apparatuses disclosed herein relate to a recyclable thermoplastic unit that includes a casing body composed of a first thermoplastic having a first melting point. The casing body also includes a first locking mechanism that is configured to mate with a second locking mechanism of a sacrifice layer. The sacrifice layer is composed of a second thermoplastic and includes the second locking mechanism. The sacrifice layer has a melting point that is greater than the melting point of the casing body.

Abstract: Seatbelt systems for generating electrical energy. The seatbelt systems may include a first and second engagement units and an electrical energy generation unit. The first engagement unit may be configured to rotate upon movement of a portion of a seatbelt in contact therewith. The second engagement unit may include at least one portion configured to rotatably engage the first engagement unit and to rotate relative to movement of the first engagement unit in an engaged position. The electrical energy generation unit may be operably coupled to the second engagement unit and configured to generate electrical energy upon rotation of the second engagement unit. Vehicles including the seatbelt systems and methods for fabricating the seatbelt systems are also disclosed.

Abstract: A seatbelt system for generating electrical energy. The seatbelt system includes a rewinding mechanism, an electrical generation mechanism, a locking mechanism, and a charging mechanism. A first rotational engagement unit of the rewinding mechanism is rotated by the movement of a seatbelt and in turn rotates a second rotational engagement unit. The rotation of the second rotational engagement unit causes the electrical generation mechanism to generate electrical energy. The charging mechanism may charge a battery with the generated electrical energy.
