A system according to at least one embodiment of the present disclosure includes a processor; and at least one inertial sensor having a known physical relationship with a tracked object in a first pose, the at least one inertial sensor providing a measurement indicative of a movement of the tracked object from the first pose to a second pose, wherein the processor determines the second pose of the tracked object based, at least in part, on the measurement provided by the at least one inertial sensor.

A mobile phone includes an acceleration sensor for detecting acceleration, a magnetic sensor for detecting magnetism, and a controller for determining a type of moving state based on the acceleration detected by the acceleration sensor and the magnetism detected by the magnetic sensor.

In order to specify a method for the standstill control of a drive body on which a friction force acts, by means of which a controlled reduction in undesirably stored potential energy is possible, an activation manipulated variable is specified which changes a setting manipulated variable which does not overcome the friction force to a relaxation manipulated variable, and the relaxation manipulated variable is converted by an actuator into a relaxation drive force acting on the drive body, wherein the activation manipulated variable is specified in such a way that the relaxation drive force overcomes the friction force, acting on the drive body, at least temporarily during the standstill control.
