Abstract: A system for controlling vehicle ride height include a suspension controller. The suspension controller is coupled to a motion sensor attached to a chassis of a vehicle and additional motion sensors each attached to a suspension member of the vehicle that pivots relative to the chassis. The suspension controller receives motion sensor data from the motion sensors and determines relative angular position of each suspension member as a function of motion sensor data received from the motion sensor attached to the chassis and motion sensor data received from the motion sensor attached to the suspension member. The suspension controller adjusts an air suspension based on the relative angular position. Other embodiments are described and claimed.

Abstract: A personal care appliance is provided that includes a brushhead for use in skincare; an appliance body having a motor assembly for oscillating the brushhead, wherein the brushhead or a portion of the motor assembly that is configured to oscillate includes a marking; and a brush encoder configured to detect the marking, and determine the oscillation of the brushhead.
