  • Method for detecting a deviation of a compression pressure of one cylinder from that of another cylinder of an internal combustion engine
    Patent number: 9709462
    Abstract: In a method for detecting a deviation of a compression pressure of one cylinder from that of another cylinder of an internal combustion engine having at least two cylinders, the rotational speed of a crankshaft of the internal combustion engine is reduced from a starting rotational speed to a target rotational speed; the actual rotational speed is detected; a curve of a change of the actual rotational speed per angle unit of the crankshaft is determined as a curve of a rotational speed gradient; the curve of the rotational speed gradient is subjected to order analysis; and a deviation of the compression pressure of one cylinder from that of another cylinder is detected when an amplitude of a selected order lies above a permissible threshold value.

  • Pharmaceutical formulations containing vitamin E TPGS molecules that solubilize lipophilic drugs without significant efflux inhibition, and use of such formulations
    Publication number: 20060165769
    Abstract: Compounds and compositions are disclosed for increasing the bioavailability of lipophilic drugs, and more specifically, to solubilizing lipophilic drugs using bioenhancers that cause no efflux inhibition or a desired degree of efflux inhibition. Methods of making and using such compositions are also disclosed.
