Patent number: 10613918Abstract: Aspects of the present disclosure are directed to assessing characteristics of stored data, as may be implemented for verification thereof. As may be implemented in connection with one or more apparatus or method-based embodiments, a first data signature is generated, which corresponds to a logical derivation of configuration data sent over a data bus. Outputs that correspond to data read out from each of a plurality of configuration registers, which receive the configuration data over the data bus, are logically combined into a second data signature. The first data signature and the second data signature are processed and compared for ascertaining that stored data, as stored in each of the plurality of configuration registers, accurately corresponds to the configuration data sent over the data bus for writing into each of the plurality of configuration registers.Type: GrantFiled: February 13, 2018Date of Patent: April 7, 2020Assignee: NXP B.V.Inventors: Peter van de Haar, Lucas Pieter Lodewijk van Dijk

Patent number: 9984257Abstract: A secure electronic apparatus and a method for determining that a secure electronic apparatus has been tampered with. The apparatus includes a memory and a plurality of sensors which each to receive an input signal and output a digital signal determined by the input signal and by a physical quantity sensed by the sensor (e.g. capacitance). A measurement routine includes applying a plurality of input signal values to the sensors and, for each input signal value, using the digital output signals of each sensor to determine a combined output result. The combined output results of the measurement routine are compared with a set of combined output results stored in the memory. A detected a difference between the combined output results of the measurement routine and the set of combined output results stored in the memory can be used to determine that the secure electronic apparatus has been tampered with.Type: GrantFiled: April 1, 2016Date of Patent: May 29, 2018Assignee: NXP B.V.Inventors: Peter Van De Haar, Franciscus Widdershoven

Publication number: 20100020928Abstract: A medical three-dimensional X-ray imaging device comprising a C-shaped arm (14) that can revolve around an axis of rotation through an object (7) to be imaged. An X-ray source (17) is attached to one end of the C-shaped arm (14), and an X-ray detector (18) for receiving X-rays is attached to the other end of the C-shaped arm (14). An attenuator (20) is present in front of the X-ray source (17), which attenuator (20) absorbs a portion of the X-rays. The degree of absorption in the central part of the attenuator (20) is lower than the degree of absorption in the part of the attenuator (20) surrounding said central part.Type: ApplicationFiled: December 22, 2005Publication date: January 28, 2010Applicant: KONINKLIJKE PHILIPS ELECTRONICS, N.V.Inventor: Peter Van De Haar

Publication number: 20060159363Abstract: The invention relates to an imaging system (15) comprising artifact reduction means (20) arranged to correct for a ring-shaped artifact in the three-dimensional reconstructed volume. The artifact reduction means (20) comprises a first stage correction means (21) arranged to eliminate the structured noise of the output screen of the image intensifier of an X-ray imaging apparatus (10) using a first corrective image. Preferably, the first corrective image (21a) is pre-calculated and is stored in a suitable memory unit of a computer (not shown). A raw image of the patient is first processed with the first corrective image (21a). The thus obtained gain-corrected image is forwarded to an image deformation correction means (23), where a suitable unwarping function (23a) is being pre-stored.Type: ApplicationFiled: July 6, 2004Publication date: July 20, 2006Inventors: Peter Van De Haar, Jan Timmer
