A brake pad for a brake apparatus may include: a friction member brought into contact with a brake disk; a back plate coupled to the friction member, and movably mounted on a torque member or a pad liner coupled to the torque member; a slide guide shim mounted on the back plate; and a slide shim movably mounted on the back plate, covering the slide guide shim, and slidably disposed on the slide guide shim.

A friction element latch device includes: a screw provided to be rotatable by receiving power from a driving source; a piston arranged to be movable by rotation of the screw; a guide arranged to selectively restrict movement of the piston; a guide pin protruding in a radial direction from an outer circumferential surface of the piston and guided by the guide; and a friction element arranged to be engaged as the piston moves.

Disclosed herein is an electromagnetic brake system. The electromagnetic brake system includes a brake disc configured to be rotated together with a drive shaft of a drive motor configured to operate a vehicle wheel, an armature disc configured to be movable so as to be in close contact with or so as to be separated from one side of the brake disc, an elastic member configured to elastically press the armature disc to the one side of the brake disc to a direction in which the armature disc is in close contact with the brake disc, and an inductor configured to separate the armature disc from the brake disc by an electrical signal. The brake disc includes a tube portion mounted on the drive shaft, and a plate portion provided to extend in an outward direction of the tube portion to be opposite to the armature disc. The tube portion and the plate portion are provided as a single member in which the tube portion and the plate portion are integrally formed with each other.

A robotic gripper may be configured to dexterously manipulate an article. The robotic gripper may include two or more fingers containing one or more rotatable contacts each. The rotatable contact may transition between a rotation mode and a braking mode such that the contacts are free to rotate in the rotation mode and are prevented from being rotated in the braking mode. In some instances, the robotic gripper may make contact with the article via the contact pads. Thus, the robotic gripper may dexterously manipulate the article via the contact pads and brake.

A cordless roller blind includes a roller tube, a blind fabric wound around the roller tube, and at least one brake device. A coil spring is arranged in the roller tube, and the torsion of the coil spring changes as the roller tube rotates. The torsion force of the coil spring, the friction force provided by the brake device and the weight of a hanging portion of the blind fabric are mutually balanced, so that the blind fabric remains stationary at any position without an external force. When the external force pushes the blind fabric to move upward, pressure acting on the brake device decreases as the external force offsets the weight of the blind fabric, and the friction decreases accordingly, and the torsion force of the coil spring drives the blind fabric to wind up.
