Abstract: The present invention provides an improved method for determining a coarse direction in an orientation system of a an autonomous device (10), for instance a dust cleaning robot together with a system of active beacons or transponders. A transmitter (20) for transmitting sensing signals is displaced in relation to the rotational center (25) of the the device (10). When the device is rotated around a vertical rotational axis in the rotational center, a minimum in the distance to the respective transponder or beacon is obtained when the transmitter of the device is positioned immediate to a point lying on a straight line between the rotational center of the device and a respective transponder, whereby an immediate coarse determination of the direction to each transponder is directly obtained. From such an immediate direction determination direct better starting values are obtained for a position calculation by means of for example Kalman filtering, by which successively from the signals obtained by these transponder responses an orientation basis is achieved for the area where the device should be acting.

Abstract: A device for measuring birefringence in an optical data carrier has a laser light source with a polarization modifier, a beamsplitter, a polarizer, a photodetector, and a controller operatively connected to the photodetector. The laser light source illuminates various spots on the optical data carrier by means of a laser beam. The photodetector receives a reflected laser beam, converts it into an electric signal and supplies this signal to the controller, which determines a value for the birefringence in the illuminated spot on the optical data carrier. Furthermore, the device is provided with a transparent reference element with known birefringence properties, a mirror, and for directing the laser beam towards the reference element in a first calibration position; directly towards the mirror in a second calibration position; and towards the optical data carrier during non-calibration time. In the first calibration position the controller calculates a first calibration value from the signal received from the photodetector, said first calibration value corresponding to a given birefringence in the optical data carrier, and in the second calibration position the controller calculates a second calibration value, corresponding to a situation essentially without any birefringence at all in the optical data carrier. These calibration values are used for determining the birefringence in a given spot on the optical data carrier.

Abstract: A laser shines light onto an object which is reflected back through a lens onto a light-sensitive measuring cell linked to a signal generating circuit, which only sends a signal when an object is detected within a given variable detection region.  Light from a laser (26) is reflected by an object (40) through a lens (20), which directs it towards a light-sensitive measuring cell (24). The optical axes (23, 27) of the laser and lens are parallel to each other. The measuring cell comprises an analogue position detector which emits signals indicating the centre point for each beam of light received. The detector is positioned below the focal point (21) of the lens and at right angles to the optical axis (23) of the lens, with most (preferably all) of its detector surface protruding sideways beyond this optical axis. The position of the lens is chosen so that light reflected by an object in front of it is focused onto the measuring cell when the object is at the very limit (30) of the detector region (28). The out ports of the detector are coupled to a signal processing circuit (32, 33) which generates a signal only when an object is detected within the adjustable detector region.

Abstract: The invention relates to a method and an arrangement for estimating a DC-offset in at least one analog output signal from an analog front end of a radio receiver in a TDMA-based radio communication system. A sequence of measurement intervals is defined (501) such that for each burst transmitted on a radio carrier frequency by mobile stations operating in a common cell, there is at least one measurement interval during which no overlap with a second burst occurs. The analog front end of the radio receiver generates (502) the analog output signal by performing analog signal processing of received radio signals. Digital samples are derived (503) from the analog output signal. A measure of received signal power in each measurement interval in a framing period is estimated (504). At least one measurement interval during the framing period is selected (505) in dependence of said measure. The DC-offset is estimated (506) using samples belonging to said selected measurement interval.
