Patent number: 11300591Abstract: For contactless current measurement at a first primary conductor that is configured to conduct a first primary current having a first current strength, and at a second primary conductor that is configured to conduct a second primary current having a second current strength, a ring-shaped magnetic core that encircles the first primary conductor and the second primary conductor detects the total magnetic field in the magnetic core and generates from the total magnetic field detected in the magnetic core a signal corresponding to the superposition of the first current strength and the second current strength. The first or second magnetic field component or individually both are also detected, and from the detected first or second magnetic field component or from both, a signal corresponding to the first current strength or a signal corresponding to the second current strength or both are generated.Type: GrantFiled: December 11, 2018Date of Patent: April 12, 2022Assignee: VACUUMSCHMELZE GMBH & CO.

Patent number: 9846181Abstract: A current sensor arrangement for measuring an effective primary current in a primary conductor having a magnetic core for magnetic coupling of the primary conductor to a secondary conductor and a controlled voltage source connected to the secondary conductor and configured to apply a voltage with adjustable polarity to the secondary conductor so that a secondary current passes through the secondary conductor. A measurement and control unit is coupled to the secondary conductor and configured to generate a measuring signal that represents the secondary current, to continuously detect the occurrence of magnetic saturation in the core, and to reverse the polarity of the voltage upon the detection thereof in order to reverse magnetization of the core. Furthermore, the measurement and control unit is configured to evaluate a spectrum of the measuring signal and determine a frequency of a current passing through the primary conductor based on the spectrum.Type: GrantFiled: July 29, 2015Date of Patent: December 19, 2017Assignee: VACUUMSCHMELZE GMBH & CO.

Publication number: 20150293153Abstract: A current sensor arrangement for measuring an effective primary current in a primary conductor is described. The current sensor arrangement comprises a magnetic core for the magnetic connection of the primary conductor to a secondary conductor, as well as a controlled voltage source that is connected to the secondary conductor and configured to apply a voltage with adjustable polarity to the secondary conductor. As a result of this, a secondary current flows through the secondary conductor. A measurement and control unit connected to the secondary conductor is configured to generate a measurement signal representing a secondary current and to continuously detect the achievement of a magnetic saturation in the core. In the case of detection of a magnetic saturation of the core, the polarity of the voltage is reversed in order to reversely magnetize the core.Type: ApplicationFiled: June 10, 2014Publication date: October 15, 2015Inventors: Steffen BOETTCHER, Holger SCHWENK

APPARATUS AND METHOD FOR GENERATING AND DISPLAYING A STEREOSCOPIC IMAGE ON A MOBILE COMPUTING DEVICE
Publication number: 20100253768Abstract: An apparatus and method for generating and displaying a stereoscopic image on a mobile computing device. The apparatus includes an autostereoscopic overlay which is secured over at least a portion of the screen of the mobile computing device, such as by using a case. Computer-readable instructions are executed on the mobile computing device to align two captured images, if necessary, and interlace them into an interlaced image for subsequent display to the screen of the mobile computing device. When the displayed image is viewed by the user of the mobile computing device through the autostereoscopic overlay, the image appears as a stereoscopic (or three-dimensional) image.Type: ApplicationFiled: March 23, 2010Publication date: October 7, 2010Applicant: Spatial View Inc.Inventors: Thomas F.
