    Abstract: A frequency synthesizer comprises a tunable oscillator (23) which provides an output signal of the frequency synthesizer, and a sampling phase detector (6) which receives the output signal from oscillator (23) and a reference signal and provides a phase difference signal representative of a phase difference between the output signal and the reference signal, which controls the frequency of the oscillator (23). The frequency of the oscillator (23) is further controlled by a frequency difference signal from a frequency detector (3), which is representative of a frequency difference between the output signal and the reference signal.

    Abstract: The invention includes a method for docking autonomous mobile units. Travel maneuvers are specified with which constricted space conditions can be taken into consideration. Further, different motion paths are recited that are to be sequentially traversed in order to locate a guide beam and in order to be able to dock reliably and dependably at a docking device. Preferably, a slot-shaped guide beam residing perpendicular to a travel surface of the unit is provided, and position-sensitive detectors for this guide beam are present on the unit, these being arranged parallel to the travel surface of the unit. The exact rotation (beta) of the unit relative to the docking device can be identified on the basis of the guide beam and the detectors, whereby the unit knows its approximate configuration in the space on the basis of ultrasound and odometry measurements. The invention can particularly be utilized in household robots or industrial robots.

    Abstract: A method is provided for improving the localization of a robot autonomous mobile unit. A slippage is predicted along a path that the unit is to traverse may be predicted, in that a simplified absolute path trajectory is determined, and based on the unit geometry and motion behavior of three-wheel kinematics, an imaginary slippage derives in the end position. This imaginary slippage can be calculated for various end positions and the most beneficial travel path can thus be selected from a starting point.
