Patent number: 7212278Abstract: The invention relates to methods and devices for recording three-dimensional distance-measuring images of an object surface by measuring light propagation time using a short-term integrated photodetector. For starting a light-induced pulse on the transmission side, a trigger signal is produced that is at the same time used on the receiving side for opening at least one integration window for receiving back-scattered light-induced pulses with a predetermined time delay. A predetermined event such as a maximum or a zero crossing is detected which, by its interval relative to the integration windows, determines a trigger delay. The trigger delay is correlated with the light propagation time and allows calculation of the object point distance d.Type: GrantFiled: August 1, 2002Date of Patent: May 1, 2007Assignee: Siemens AktiengesellschaftInventors: Günter Doemens, Peter Mengel

Publication number: 20050068544Abstract: A cost-effective panoramic scanner provides for the three-dimensional detection of objects, and in particular for the detection of ear impressions. For this purpose, a pattern is projected onto an object to be detected via a projector that generates an object image via a camera, the object image containing images of markings that enable an unambiguous assignment of the position of the object with respect to the projector and the camera. Since an exact synchronization of the rotary movement of the object with the recording of the object images is not necessary by virtue of the markings, the precision of the mechanism used is relatively nonstringent.Type: ApplicationFiled: September 24, 2004Publication date: March 31, 2005Inventors: Gunter Doemens, Frank Forster, Torsten Niederdrank, Peter Rummel

Publication number: 20040233416Abstract: The invention relates to methods and devices for recording three-dimensional distance-measuring images of an object surface by measuring light propagation time using a short-term integrated photodetector. For starting a light-induced pulse (1) on the transmission side, a trigger signal is produced that is at the same time used on the receiving side for opening at least one integration window (2, 21, 22) for receiving back-scattered light-induced pulses (3) with a predetermined time delay (&Dgr;TV). A predetermined event such as a maximum or a zero crossing is detected which, by its interval relative to the integration windows, determines a trigger delay. Said trigger delay is correlated with the light propagation time and allows calculation of the object point distance d.Type: ApplicationFiled: February 5, 2004Publication date: November 25, 2004Inventors: Gunter Doemens, Peter Mengel

Patent number: 6439333Abstract: In order to trigger an airbag in a differentiated way, the position of a vehicle occupant is determined in a way that is as immune to interference as possible. This is achieved by a distance measurement in which the seatbelt that is in contact with the vehicle occupant serves as an active reference position. The distance between the seatbelt and known points within the vehicle permits the position of the seatbelt and the vehicle occupant to be determined. The distance measurement is performed using magnetic field transmitter units and receiver units. The transmitter unit is preferably integrated into the belt.Type: GrantFiled: March 23, 2001Date of Patent: August 27, 2002Assignee: Siemens AktiengesellschaftInventors: Günter Dömens, Peter Mengel

Patent number: 5991040Abstract: In addition to triangulation methods, measurement systems according to the confocal principle are employed for the three-dimensional sensing of surfaces. These measurement systems have a higher resolution but, under certain circumstances, a lower data rate. An optical proximity sensor is described which, on the basis of the confocal microscope, carries out automatic inspection of surfaces in a time which is acceptable for a fabrication process. A linear system of corresponding light sources and photo receivers is used instead of a scanning beam, which requires a high outlay for generation. The optical path length between the receiving unit and the optical imaging arrangement is varied for the resolution of height values, wherein a light intensity maximum is detected by a peak detector.Type: GrantFiled: December 23, 1997Date of Patent: November 23, 1999Assignee: Siemens AktiengesellschaftInventors: Gunter Doemens, Anton Schick, Paul Kollensperger

Patent number: 5827980Abstract: The force or extension sensor has a measuring capacitor (Mk) whose comb-like, interlocking electrode structures (Es1, Es2) can be adjusted in parallel with one another by two attachment points (Bp1, Bp2) as a function of the force (F) or the extension (E) to be measured. The total capacitance of the measuring capacitor (Mk) is determined by a parallel circuit having individual electrode pairs. A change in the total capacitance of the measuring capacitor (Mk) which is brought about by a change in the distances (d1) between the electrodes provides information on the force (F) or the extension (.epsilon.) to be measured. A change in the distances between the electrodes as a result of temperature-related extension is at least largely avoided by virtue of the fact that the attachment points (Bp1, Bp2) lie on a junction line (V1) which runs parallel to the direction of the electrodes (E1, E2) and is oriented at an angle (.alpha.) of 40.degree. to 50.degree., preferably 45.degree.Type: GrantFiled: February 11, 1997Date of Patent: October 27, 1998Assignee: Siemens AktiengesellschaftInventors: Gunter Doemens, Markus Gilch

Patent number: 5750904Abstract: The force or extension sensor has a measuring capacitor (Mk) whose electrode structures (Es1, Es2), of comb-like design and interengaging, can be moved parallel to one another via two securing points (Bp1, Bp2) as a function of the force (F) to be measured or of the extension (.di-elect cons.) to be measured. The total capacitance of the measuring capacitor (Mk) is determined by parallel connection of individual electrode pairs. The variation in the total capacitance of the measuring capacitor (Mk) due to variation of the electrode separations (d1) gives information regarding the force (F) to be measured or the extension (.di-elect cons.) to be measured.Type: GrantFiled: February 11, 1997Date of Patent: May 12, 1998Assignee: Siemens AktiengesellschaftInventors: Gunter Doemens, Markus Gilch

Patent number: 5687475Abstract: In order to determine the position and/or to check the separation of the leads (A) of components (B), a direct shadow of the region of the leads at one side of the component is generated on the photosensitive surface of a local resolution optoelectronic transducer (W4). If in each case one shadow is generated successively from two different directions, the coplanarity of the leads (A) may also be checked. Preferably, the local resolution optoelectronic transducer (W4) and the light sources for casting the shadow are directly secured to the equipping head (BK4). By integrating the determination system into the equipping head, the lead position can be determined and the separation and coplanarity of the leads can be checked without delay.Type: GrantFiled: April 1, 1996Date of Patent: November 18, 1997Assignee: Siemens AktiengesellschaftInventor: Gunter Doemens
