Abstract: The present application relates to the field of local-dimming, and in particular, relates to a flexible circuit board and a multi-zone dimming functional element. The flexible circuit board specifically includes a first independent circuit group and a second independent circuit group. The first independent circuit group includes multiple first independent circuits, each contacting a dimming area of ??the functional element and connecting the dimming area to a control unit. The second independent circuit group includes multiple second independent circuits and at least one temperature sensor for measuring the temperature of the functional element within a temperature measurement area. Integrating the first terminal, second terminal, and temperature sensor on the flexible circuit board reduces the number of connectors and solder joints, improving the system's integration and reliability.

Abstract: This disclosure provides an electrical connection structure of one or more segments of intelligent dimming films, which specifically comprises a dimming film body, a flexible circuit board and a control unit. Among them, U-shaped long grooves are designed between the independent circuits of the flexible circuit board, and ventilation holes are set on the conductive adhesive film layer connecting the dimming film body and the flexible circuit board. The design of the electrical conduction structure of the dimming film of this disclosure not only uses ACF conductive adhesive lamination instead of solder paste welding technology to avoid the risk of circuit false soldering, but also performs special design on FPC and ACF conductive adhesive to improve the operating stability of the dimming film and avoid the risk of short circuit and open circuit caused by line connection.

Abstract: An apparatus for a brake drum of a vehicle having a drum brake assembly with first and second brake shoes includes a motor with a pinion gear. A ball screw assembly has a nut for receiving torque from the pinion gear and a spindle threaded with the nut. The nut is aligned with the first brake shoe and the spindle is aligned with the second brake shoe. The motor is actuatable for rotating the nut to move the nut and the spindle away from one another for moving the brake shoes to apply braking force to the brake drum during a braking event. A bi-stable locking mechanism selectively locks the motor to prevent torque transfer from a back-driving ball screw assembly to the motor.

Abstract: An aerodynamic body with an aerodynamic body surface that creates a contoured surface for a fluid to stream around, with a device to influence the flow of the fluid streaming around the aerodynamic surface. The flow-influencing device includes a passage to link the fluid streaming around the aerodynamic surface with an actuator space of an aspirating and purging device situated in the aerodynamic body, and an indentation that is situated next to the passage, which is formed by a recessed section of the aerodynamic surface on a flow-influencing region within the contoured surface of the aerodynamic surface, so that a boundary wall is configured as part of the recessed surface lying opposite the indentation. The aspirating and purging device can generate a swirl in the flow of the fluid streaming around the aerodynamic surface, the rotational axis of which is directed along the assumed aerodynamic body chord direction.

Abstract: The invention rests on the idea that the information for controlling an EC-motor is taken from the adjustment or position of the control unit, which can be ascertained by means of a position indicator, such as a potentiometer, Hall indicator, etc. The current pattern for the EC-motor can thereafter, for example, be determined in a microcomputer disposed in the motor control for the control unit, without the motor having a rotor position determination.

The stator windings are supported by stator pole shanks comprising, radially inside, stator pole shoes facing the rotor pole shoes. Via a short circuit bridge, the stator pole shoes are connected with the adjacent stator pole shoes so that all the stator pole shanks are integrally formed with each other. Radially outside, the stator pole shanks and stator pole shoes are connected with each other only by a separate yoke ring set thereon. All the windings are wound from radially outside with one single continuous winding wire when the yoke ring has been removed.
