A microwave cooking appliance having power management. The appliance may include at least one cord positionable between at least one stowed position to at least one deployed position. The appliance may include one or more strain relief members stopping the deployment of the cord. The microwave cooking appliance may include a cord housing. The microwave cooking appliance may include a pulley engaging the cord. The microwave cooking appliance may include a biasing member engaging the pulley and/or cord. The microwave cooking appliance may include a pin and slot engagement engaging the pulley and/or cord.

A Venetian blind includes two string reels, two spring reels, a leaf spring and a wheel set. The string reels are engaged with each other. The spring reels engaged with each other. The leaf spring includes two sections respectively wound on the spring reels so that one of the sections of the leaf spring gets longer and the remaining one of the sections of the leaf spring gets shorter when the spring reels are rotated. The wheel set connects one of the string reels to one of the spring reels. None of the spring reels is engaged with any of the string reels without the wheel set.

A retractable reel system includes a reel, a gear assembly, a paddle wheel and a spring. The reel includes a concentric wheel shaft where the reel and wheel shaft rotate to wind and unwind a length of material from the reel. The gear assembly engages with an end of the wheel shaft to provide a gear reduction ratio between the wheel shaft and an output shaft of the gear assembly. The paddle wheel is connected to and concentric with the output shaft, and the paddle wheel includes a paddle that extends beyond an outer edge of the paddle wheel that rotates with the paddle wheel. The spring is arranged outside the outer edge of the paddle wheel. The spring is compressed by the paddle to store an energy when the reel is rotated to unwind the length of material from the reel. The stored energy is used to rotate the reel to wind the length of material around the reel.

A window shutter actuation device includes a cord for driving window shutter slats to move, a retracting mechanism for winding an end of the cord away from the window shutter slats, a brake mechanism arranged between the retracting mechanism and the window shutter slats for controlling a retracting or releasing speed of the cord, and a power mechanism for driving the retracting mechanism to rotate to wind the cord. The retracting mechanism includes a frame, a reel rotatably mounted to the frame for winding the cord, and a wheel arranged outside and adjacent to an end of the reel. The end of the cord wound on the reel passes about the wheel and then extends to the brake mechanism after extending from the reel.

A retaining device assembly. The retaining device assembly may include an attachment element. The retaining device assembly may further include a housing coupled to the attachment element. The housing may include a self-winding reel. The retaining device assembly may further include a line coupled to the housing through the self-winding reel. The retaining device assembly may also include a releasable coupling coupled between the line and the attachment element.

A retractor restraint system is provided for securing wheelchairs and/or people in vehicles. The system includes a housing, a retractor reel mounted to the housing rotatably in a positive and a negative direction of rotation for receiving a belt which can be coupled to a wheelchair, an arresting unit for arresting the reel to prevent rotation in the negative direction of rotation in an operating state of the retractor restraint system, a clamping unit arranged at the housing for releasably clamping fast the belt unwound from the reel, and a triggering mechanism for actuation of the clamping unit. The triggering mechanism is coupled to the arresting unit and the reel in such a way that the clamping unit is actuated when a torque acts on the reel in the negative direction of rotation and the reel is arrested by the arresting unit.
