Patent number: 8275509Abstract: System and method for detecting and storing at least speed as an information relevant for resignation for a tachograph system. to provide a tamperproof tachograph system offering a high degree of security. An arithmetic unit detects signals for determining the speed from at least two independent sensors and compares them with each other and stores a sensor-related error message if the signals deviate significantly from each other. The signals of at least three independent sensors are compared with each other in the arithmetic unit and are checked for their plausibility by excluding any signals that significantly deviate from a plurality of signals and determining the speed of the vehicle to be stored only using one or more of those signals that deviate from each other only within defined limits.Type: GrantFiled: August 28, 2007Date of Patent: September 25, 2012Assignee: Continental Automotive GmbHInventors: Gerd Fritsch, Gunnar Schmidt

Publication number: 20110219766Abstract: An arrangement for supplying fresh gas to a turbocharged internal combustion engine having an intake line and an exhaust gas line, includes an exhaust gas turbocharger having a compressor impeller for compressing fresh gas and feeding the compressed fresh gas to the internal combustion engine, and having a drive impeller for driving the internal combustion engine with exhaust gas for driving the compressor impeller. The arrangement also includes a compressed air supply system for the controlled supply of compressed fresh gas or compressed air to the internal combustion engine. The compressed air supply system is connected via a charge air intake to the compressor impeller, via an outlet to the intake line, and via a compressed air inlet to a compressed air source. The compressor impeller of the exhaust gas turborcharger is composed completely of partially of steel or a steel alloy.Type: ApplicationFiled: March 21, 2011Publication date: September 15, 2011Applicant: KNORR-BREMSE Systeme fuer Nutzfahrzeuge GmbHInventors: Manuel MARX, Gerd Fritsch, Huba Nemeth

Patent number: 6713269Abstract: A method of screening potential therapeutic substances that may be useful in the treatment of osteoporosis is provided herein utilizing primary osteoblast precursor cell cultures to determine the mitogenic effect of the tested agents. This method comprises preparation of the primary cultures from osteoporotic patients for the expression of several intracellular proteins in early and late osteoblast differentiation phases, expression of other proteins involved in matrix synthesis, and quantitative analysis of the cellular proliferation rate. The expression of such intracellular proteins and cell proliferation in the cultures derived from osteoporotic patients are quantitatively compared to primary osteoblast cell cultures from non-osteoporotic patients that are standardized for the same approximate age and sex.Type: GrantFiled: March 27, 1998Date of Patent: March 30, 2004Assignee: co.don AktiengesellschaftInventors: Olivera Josimovic-Alasevic, Karl-Gerd Fritsch, Jochen Ittner
