2045591 9008128 PCTABS00001 Compounds of formula (I), wherein D represents the dehydrogenated residue of a hydroxyl group-containing drug or the dehydrogenated residue of an NH-acidic group-containing drug; the substituents in the phenyl ring .alpha. and .beta. are in either meta- or para-position to each other; and the phenyl ring additionally may be substituted; m is an integer of 0 or 1; p...

The quantification device has an ultrasonic transducer, which is positioned on the subject in proximity to the bladder, ad excited by a logic-controlled pulser/receiver to introduce an acoustic wave into the patient. This wave interacts with the bladder walls and is reflected back to the ultrasonic transducer, where it is amplified and processed by the pulser/receiver. The resulting signal is digi...

In a method and an apparatus for controlling a motor used in the lifting and lowering operation of a window blind or an awning the rotation of the motor rotor is used for delivering signals to a signal receiving means. The signal receiving means in turn delivers signals to stop the motor at the end positions of the blind or awning.
