A magnetic sensor arrangement (1), having magnetically sensitive sensor elements (7, 8) whose electrical properties are changeable as a function of a magnetic field that a moving, passive transmitter element (11) is able to influence. The magnetic sensor arrangement (1) has two sensor elements (7, 8) in a gradiometer arrangement that are each respectively associated with one of two magnetic regions (4, 5) of a permanent magnet embodied in the form of a gap magnet (2; 20; 23), which regions are spaced apart from each other by a predetermined distance (sa). The regions (4, 5) and the gap magnet (2; 20; 23)—in terms of the for example wedge-shaped embodiment, the dimensions (h, b, t), the gap width (sa), the gap depth (st), and their positions in relation to the sensor elements (7, 8)—are situated so as to minimize the offset of the output signal of the sensor elements (7, 8) in the gradiometer arrangement.

The invention relates to a method for eliminating error elements caused by movements of an imaged object in X-radiography, said method comprising performing X-radiography on an imaged object for compiling three-dimensional X-radiographic information. The method comprises creating a model geometry of an X-ray imaging process, said creation work comprising a determination of the location for two or more position markers in a set of coordinates graded for an X-ray imaging apparatus. When X-radiography of an imaged object is completed, predictions are worked out regarding the locations of position markers during the imaging session. The locations and predictions determined on the basis of the model geometry are used as a basis for defining projected or most likely locations for the position markers and an automatic position markers identification method is applied for finding the locations of position markers from within a search area in the X-radiographic information. When the locations of at least two position markers have been found with the automatic position markers identification method, a minimization of offsets between the projected locations of position markers and the locations of position markers looked up by the automatic identification method is performed by searching for a minimum point of the function for eliminating the error elements resulting from movements of an imaged object.

A conversion circuit increases a gain of an analog-to-digital converter (ADC) preamplifier by minimizing a common mode offset voltage between an input signal and a reference signal. The feedback controller circuit calibrates an input common mode voltage to mitigate a common mode offset voltage. Reduction of the common mode offset voltage increases the gain of the ADC preamplifier. In an example, the method is executed during a hold phase of a track-and-hold circuit that transmits the input signal to the ADC.

A divergent flap assembly of a gas turbine engine includes a hotsheet, a backbone structure for supporting the hotsheet, and a plow portion secured to the backbone structure to bridge a gap between the hotsheet and an external flap. The plow portion is fabricated from CMC material and has external geometry to complement and substantially continue geometry of the external flap to minimize plane detection. The plow portion is attached to the backbone structure such that when the backbone structure thermally expands, the plow portion is shifted to minimize an offset between a trailing edge of the hotsheet and the plow portion. The plow portion is fastened to the backbone structure by a plurality of fasteners, which are arranged to minimize thermal stresses.

A radio transceiver includes circuitry that enables received RF signals to be down-converted to baseband frequencies and baseband signals to be up-converted to RF signals prior to transmission without requiring conversion to an intermediate frequency. The circuitry includes a temperature sensing module that produce accurate voltage level readings may be mapped into corresponding temperature values. A processor, among other actions, adjusts gain level settings based upon detected temperature values. One aspect of the present invention further includes repetitively inverting voltage signals across a pair of semiconductor devices beings used as temperature sensors to remove a common mode signal to produce an actual temperature-voltage curve. In one embodiment of the invention, the circuitry further includes a pair of amplifiers to facilitate setting a slope of the voltage-temperature curve.

An apparatus is capable of restoring a clock of a second node in a communication system with a symmetric network construction of a first node that is capable of receiving a Global Positioning System (GPS) signal, and the second node that is not capable of receiving a GPS signal. The method includes identifying synchronization information received from the first node, determining a delay with the first node, generating a clock using the synchronization information and delay, removing a clock phase being out of a reference range in a phase identification interval, dividing the phase identification interval into at least two subdivision intervals, and removing a clock phase being out of a normal operation range of a phase in each subdivision interval.
