Abstract: This disclosure discloses a power management method and device, applied to power management of an electronic device. The method includes the following processing: obtaining an IMU PM execution notification before an OS runs, where the IMU PM execution notification is sent by boot firmware after the boot firmware determines, before the OS runs, that power management PM is to be performed by the IMU firmware; after determining, based on the IMU PM execution notification, that PM is to be performed on a CPU obtaining a current performance parameter of the CPU, where the performance parameter includes one or more of power consumption, a temperature, and usage of the CPU (302); and performing power management on the CPU based on the performance parameter (303). Power management is performed so that interaction procedures between the OS and the IMU firmware can be reduced, so that the power management is more efficient.

Abstract: A friction device for a torsional vibration damper includes an axis of rotation, an input side with a first disc and a second disc, and an output side between the first disc and the second disc and rotatable relative to the input side. The output side has a first friction disc, a second friction disc, and a spring element between the first friction disc and the second friction disc. The spring element has first, second and third contact regions. At a first angle of rotation between the input side and the output side, an axial contact force between the first friction disc and the second friction disc is transmittable via the first contact region and the third contact region. At a second angle of rotation, different than the first angle of rotation, the axial contact force is transmittable via the second contact region and the third contact region.

Abstract: A brake system comprising a torque limiter assembly that sets a torque limit and associated with an electromechanical actuation system. The torque limiter assembly comprises a ring gear meshed with two or more planetary gears, the ring gear comprising a first race extending circumferentially therearound. The torque limiter assembly comprises a pre-loaded member comprising a second race extending circumferentially therearound. Balls are engaged between the first and second races. The first and/or second races comprise a series of peaks and valleys, and slopes extending therebetween. Below the torque limit, the balls are engaged within the valleys causing the ring gear to remain rotationally captive and the planetary gears to orbit. At and above the torque limit, the balls slip over the peaks, causing the ring gear to rotate and the planetary gears to remain orbitally captive.
