Patent number: 12212256Abstract: A method and a control apparatus for determining parameters for controlling an electric drive having an electric machine improve the start-up of the electric drive by applying a current indicator as a signal at three-phase winding connections of the electric machine, and measuring a d-component and a q-component of the stator voltage and of the stator current at the winding connections. In a first measurement step, a rotating current indicator is applied to the three-phase winding connections and the electric machine is oriented such that an exciter current in the q-axis assumes a minimum. In a second measurement step, when the rotor of the electric machine is stationary, a field winding of the electrical machine is short-circuited and a current indicator in form of a binary noise signal is applied to the winding connections. A stator impedance is then determined as a first control parameter.Type: GrantFiled: August 25, 2021Date of Patent: January 28, 2025Assignee: Siemens AktiengesellschaftInventors: Folke Giessler, Mathias Lehmeier, Peter Stark, Harald Wiechmann

Patent number: 8029658Abstract: The present invention concerns a device and a method for filtering molecules that is precise, efficient, reliable, and rapid; it has a low rate of molecular loss, it can be upgraded, and it provides for the automated filtration of molecules according to one or more predefined parameters. The device (10) for filtration of molecules (3) comprises three filtration zones (11a-11c), each equipped with filtration reservoirs (1) in which a solution containing molecules (3) to be filtered is placed. The filtration reservoirs (1) are separated into two chambers by an isoelectric filter (4) which allows only selective passage of molecules (3) according to their isoelectric point (pI) when they are subjected to an electrical field generated by electrodes (5). This filtration device (10) comprises a mechanized tool holder (20) specifically for supporting one or more pairs of electrodes (5) in order to perform isoelectric filtration in one or more filtration reservoirs (1) simultaneously.Type: GrantFiled: March 18, 2005Date of Patent: October 4, 2011Assignee: Portmann Instruments A.G.Inventor: Peter Stark

Patent number: 7433030Abstract: Apparatus (10), systems and methods are disclosed for treating a biological fluid with light. A container (206) of biological fluid is introduced into a fluid treatment chamber (40) where it is contacted with light provided by one or more light sources (60, 70) in proximity to the fluid treatment chamber (40). A light sensing system (650) senses the intensity of illumination of the light. A radiometer (460) may be inserted into fluid treatment chamber (40) to calibrate the light sensing system (650). An electronic control system (600) utilizes an interface circuit board (606) to interface a computer circuit board (602) to a display panel (37), a user interface panel (39, 39a), a relay circuit board (640), light sensors 404 and various other sensors (649).

Publication number: 20080037800Abstract: An electronic stethoscope having several modes of operation to process acoustic signals to provide filtered signals useful for diagnosis. In one mode of operation the stethoscope substantially provides only acoustic signals generated by biological activity of the heart. In another mode of operation, the acoustic stethoscope substantially provides only acoustic signals generated by biological activity of the lungs. In another mode of operation, the electronic stethoscope disproportionately amplifies abnormal heart sounds and normal heart sounds to enhance diagnosis of heart abnormalities. The electronic stethoscope is operated in a manner similar to a conventional acoustic stethoscope and has similar spectral characteristics, thus allowing a user with acoustic stethoscope experience to easily use the electronic stethoscope.Type: ApplicationFiled: March 2, 2007Publication date: February 14, 2008Inventors: James Grasfield, David Winston, John Purbrick, Peter Stark, Daniela Steinhubel
