Sensor fusion algorithm techniques are described. In one or more embodiments, behaviors of a host device and accessory devices are controlled based upon an orientation of the host device and accessory devices, relative to one another. A combined spatial position and/or orientation for the host device may be obtained based on raw measurements that are obtained from at least two different types of sensors. In addition, a spatial position and/or orientation for an accessory device is ascertained using one or more sensors of the accessory device. An orientation (or position) of the accessory device relative to the host computing device may then be computed based on the combined spatial position/orientation for the host computing device and the ascertained spatial position/orientation for the accessory device. The relative orientation that is computed may then be used in various ways to control behaviors of the host computing device and/or accessory device.

In order to reduce the stresses occurring during the closing of a manually closable body component, e.g. a door, a method of controlling the closing movement is proposed in which,

• • during the closing movement, departing from an opened position, the body component passes through a first movement range in which the body component is moved towards the closed position without any action by a control member, and,
  • following the first movement range, the body component passes through a second movement range in which the closing movement of the body component is varied in such a manner by the action of the control member that the residual kinetic energy of the body component does not exceed a predetermined limit value after passing through the second movement range, irrespective of the initial speed.

The residual kinetic energy is not sufficient to close the body component automatically. The body component is therefore automatically drawn in a third movement range following the second movement range until a pre catch or main catch of a lock is reached.

The invention relates furthermore to a corresponding control device.

The present invention relates to a door operating system for controlling the movement of a door, more particularly to “no touch” door openers for public washrooms and households.
