Abstract: A method is provided for validating annotations of objects. Spatial datapoints acquired by a sensor and annotation data are received. The annotation data is associated with the acquired spatial data points and includes an identification of each respective object. Via a processing unit, the annotations of the objects are validated by performing the steps of: determining a target range for at least one property of the objects, determining, from the acquired spatial datapoints and/or from the annotation data, a respective value of the at least one property for each respective object, and for each object, identifying the object as an erroneous object if the respective value of the at least one property is outside the target range for the at least one property. The erroneous object is selected for review regarding erroneous annotation.

The UWB receiver includes a down-conversion mixer coupled to the first switch and providing an IF signal; an integrator that receives the IF signal, the integrator being switched on and off at a periodic repetition frequency (PRF); a sample and hold circuit coupled to the integrator; a first phase switch that is switched at PRF/2 coupled to receive a signal before the integrator; a second phase switch coupled to the sample and hold circuit, the second switch also being switched at PRF/2; and a low-pass filter coupled to the second switch, wherein l/f noise is filtered out by the low-pass filter.

Abstract: A circular comb of a combing machine has a base body oriented parallel to a rotational axis of the circular comb, the base body including an inner support surface and a radially oriented opening. A comb element is disposed on an outer circumference of the base body, and a retaining element having a threaded bore is connected to the comb element. A threaded bolt has a threaded first section that engages into the threaded bore, a middle section that protrudes through the radially oriented opening the in base body, and a second end section supported on the inner support surface of the base body. A diameter of the first end section of the threaded bolt is smaller than a diameter of the middle section. A spring element is provided between the inner support surface of the base body and the second end section of the threaded bolt.

Abstract: Compounds of the formula 1 wherein, R is hydrogen, alkyl or substituted alkyl, aryl or substituted aryl, are useful intermediates in the synthesis of fragrance ingredients such as Ambrox 2

Abstract: In a rapid coupling, a pipe nipple engages a through hole of a socket. A first annular groove provided on the pipe nipple serves to catch a locking ring provided in the socket, in order to lock the coupled condition. A sleeve is movable on the pipe nipple, the sleeve having an inner projection to be retained by the first annular groove of the pipe nipple in a pre-assembled condition. When the pipe nipple is inserted into the socket, the sleeve abuts the socket and is then moved along the pipe nipple until the inner projection is caught by a second annular groove if the coupling is properly locked. It the pipe nipple is not moved into the socket to such an extent that the locking ring is caught by the first annular groove, the second annular groove remains visible outside the sleeve to indicate the improper coupling condition.
