Methods for fastening or coupling dissimilar materials to each other may include providing a first component with a first through hole and a second component with a second through hole that is at least partly aligned with the first through hole. A mixture including a first material and a second material may be injected into the aligned through holes of the first component and the second component. The mixture of the first material and the second material may expand in the through holes, e.g., due to a chemical reaction, thereby connecting the first component and the second component together.

According to one aspect, a glass-free pre-impregnated material includes a polybenzimidazole (PBI) sheet and a partially cured resin encapsulating the PBI sheet. According to another aspect, a process of forming a glass-free pre-impregnated material includes encapsulating a PBI sheet within a resin and partially curing the resin to form the glass-free pre-impregnated material. According to yet another aspect, a printed circuit board comprises a glass-free dielectric layer that includes a PBI sheet encapsulated within a cured resin.

A composite structure for stab protection includes layers of flat structures placed on top of each other, and an embedding material, wherein, in at least some of the layers placed on top of each other, the flat structures of adjacent layers are offset relative to one another, the flat structures of the composite structure are at least partially embedded in the embedding material, and the composite structure includes separated connecting elements, wherein before they are separated, the separated connecting elements have connected at least some of the flat structures of adjacent layers with one another.

A security document with unidirectional visual illumination is disclosed. A security feature is positioned within the document and not visible in normal ambient lighting conditions but becomes visible under specialized lighting conditions, for example in the presence of ultraviolet light. The security feature is constructible such that it is visible only from a single side of the security document, with the side being predeterminable regardless of the orientation of the specialized light.

An electric vehicle thermal management system and an electric vehicle using the thermal management system, wherein a passenger cabin is heated by the heat dissipated from a battery and/or a motor, and the battery and the electric motor are connected in different cooling paths. Heat is supplied to the passenger cabin by using the heat absorbed by cooling liquid from the battery and/or the motor, so that the electric power of the electric vehicle can be effectively utilized to increase the endurance mileage of the electric vehicle.

There is provided a component formed from a plurality of laminates stacked on one another, thereby defining a stacked laminate structure having a leading edge and a trailing edge. Each of the plurality of laminates is formed from a ceramic matrix composite material. In addition, a plurality of interior cooling channels are defined within an interior of the stacked laminate structure and extend longitudinally between the leading edge and the trailing edge. A metal support structure is arranged so as to extend through first openings in the laminates and through the stacked laminate structure.

The present invention relates to the display technology field, and provides a backplate, a plastic-iron integrated structure, a backlight unit, and a display device. The backplate is provided with a first through hole, and the first through hole has an inner wall and an outer wall which form a projection structure on the backplate. When the backplate is bonded with a plastic frame to form the plastic-iron integrated structure, the plastic frame not only contacts the inner wall of the first through hole, but also contacts the surface of the projection structure, thus increasing the contact area between the plastic frame and the backplate, and increasing the bonding force between the plastic frame and the backplate. Even when the plastic frame shrinks in case of fluctuations in temperature and/or humidity, the plastic frame is not easily separated from the backplate, and the stability of the formed plastic-iron integrated structure is improved.

The present disclosure relates to a thermal dissipation system of an electric vehicle that includes: a heat exchanger arranged at the front part of the electric vehicle for providing heating or cooling to an air conditioning system of the electric vehicle; a first heat sink and a second heat sink, which are respectively arranged at the two sides of the front part of the heat exchanger; a number of rotatable and adjustable air deflectors for changing the flow direction of the air flowing through the heat dissipation system. Temperature sensors are included within the thermal dissipation system for sensing the working temperatures and the environmental temperatures of a battery pack and a motor of the electric vehicle. Opening and closing states of the air deflectors are adjusted in accordance with data provided by the temperature sensors.

Vehicle operating systems for operating a vehicle having a driving seat for a vehicle driver and at least one passenger seat for passengers are described. The vehicle operating system may include one or more camera devices for shooting images of hand actions of the driver or images of hand actions of a passenger, and a storage device for storing operating signals corresponding to hand actions. A processing device may be configured to select the driver or the passengers as a gesture command operator, and to control the camera device to shoot hand action images of the selected gesture command operator. The command system may also be configured to convert the shot hand action images into corresponding operating signals according to hand action indicia stored in the storage device. The operating signals may be sent to execution devices, that execute the corresponding operations.

Disclosed embodiments may relate generally to manufactured elements having composite reinforcement, and more specifically to elements comprising a composite precisely positioned within the element for support. Embodiments of such elements typically may be formed using injection molding. Embodiments may further comprise an integral thermoplastic positioning system for positioning the composite, and encapsulating thermoplastic forming the exterior geometry of the element.
