Patent number: 7706581Abstract: In a method and an arrangement for detecting skinprints, in particular fingerprints, it is provided that at least one strip sensor comprising at least one elongate narrow sensor line detects the structure of the fingertip when the fingertip passes over the strip sensor, that at least one optoelectronic speed sensor continuously determines the finger movement, that the fingertip is moved over at least one optoelectronic speed sensor and the strip sensor, and that the determined finger movement is used to correct an image of the finger structure that has been distorted as a result of non-uniform movement. Preferably, the speed sensor evaluates the Doppler shift of a modulation of the modulated laser light reflected at the moved finger surface.Type: GrantFiled: August 30, 2004Date of Patent: April 27, 2010Assignee: NXP B.V.Inventors: Steffen Drews, Rene Duijve, Thomas Hase, Karl-Ragmar Riemschneider

Publication number: 20080097704Abstract: The invention relates to an arrangement for monitoring pressure within a battery cell, comprising: at least one battery cell, and at least one strain gauge for monitoring mechanical deformation of the battery cell. The invention also relates to a method of monitoring internal pressure of a battery cell, preferably by making use of such an arrangement.Type: ApplicationFiled: January 16, 2006Publication date: April 24, 2008Applicant: KONINKLIJKE PHILIPS ELECTRONICS, N.V.Inventors: Peter Notten, Georg Hetzendorf, Karl-Ragmar Riemschneider

Publication number: 20080024322Abstract: It is proposed that passive wireless transponder systems used in the context of procedures for access identification be provided with signaling that can be perceived by human beings. This also makes it possible to detect that a relay attack, which is difficult to prevent, is being carried out. Attention is also drawn to other types of manipulative interference with the communication and to certain problems with the high-frequency transmission. By the employment of comparatively inexpensive and highly reliable means, this near-simultaneous perception of an identifying process for access purposes produces a very effective reduction in such threats to the security of the system. Other simple measures may have an advantageous effect in connection therewith. The signaling may also assist an ergonomic process. For example, an automobile entry or access system that is not specifically actuated, referred to as a passive keyless entry system, may be improved.Type: ApplicationFiled: June 17, 2004Publication date: January 31, 2008Applicant: Koninklijke Philips Electronics N.V.Inventors: Karl-Ragmar Riemschneider, Horst Roehm, Matthias Wendt, Thomas Durbaum, Achim Hilgers, Rainer Pietig, Heiko Pelzer

Publication number: 20060152190Abstract: Measurement of physical properties and individual charge control of the cells of a battery may lead to a longer battery life and to a more reliable operation. The present invention discloses a system, a cell unit, a control unit and a method for the automated management of batteries via a wireless communication link. According to the invention, the life cycle of individual cells of a battery may be tracked and recorded by an external control unit. Advantageously, active control of the battery cells is provided, including the ability to provide a short circuit between respective poles of battery cells.Type: ApplicationFiled: November 5, 2003Publication date: July 13, 2006Applicant: Koninklijke Philips Electrontics N.V.Inventor: Karl-Ragmar Riemschneider

Publication number: 20050231330Abstract: In a method and a device for the communication of microelectronically integrated data carriers, which contain contactless communications devices, at least two data carriers are brought into the reciprocal range of their contactless communications devices, at least one component (field generator) generates an alternating electromagnetic field, by means of which the data carriers are supplied with sufficient energy for the internal processing and communications operations, and data can be transmitted directly from at least one of the data carriers to at least one other data carrier.Type: ApplicationFiled: May 9, 2003Publication date: October 20, 2005Applicant: KONINKLIJKE PHILIPS ELECTRONICS N.V.Inventors: Steffen Drews, Karl-Ragmar Riemschneider

Publication number: 20020089442Abstract: A method and apparatus for altering the coordinates obtained by satellite navigation in a receiving system which fixes an incorrect position, instead of a true position, within a given three-dimensional zone. In connection with altered coordinates, additional navigational information such as course and speed can also be influenced. Specifically, signals are received from a site and re-emitted in a suitable way so that a navigation receiver determines the position of the receiving site within the three-dimensional zone covered by the emission. This approach is superior to noise-blanketing countermeasures (such as carrier or noise interference) in that precise but untrue coordinates are determined in the navigation receiver, without this incorrectness being immediately recognized.Type: ApplicationFiled: January 11, 2002Publication date: July 11, 2002Applicant: NAUTISCH-ELEKTRONISCHE TECHNIKInventors: Karl-Ragmar Riemschneider, Franz Wolf
