Abstract: Exact data-rate analysis of the information signal portions to be transmitted in a subsequent transmission cycle per time-division multiplexing process shall be initially omitted. Instead, on the basis of highly accurate estimated values for the subsequent data rates, estimated values for relative waiting times are transmitted, in a current transmission cycle, from the current time slice to the subsequent time slice of the same service. In the subsequent transmission cycle, actual data rates may be set which may deviate from the estimated data rates for the individual information signals, as a result of which predicted time-slice boundaries for the subsequent transmission cycle may shift. However, the potential shift in the time-slice boundaries is subject to several boundary conditions. No time slice of the subsequent transmission cycle can start prior to its signaled estimated starting time. With constant data rates, the estimated time-slice structure and the actual time-slice structure are identical.

Abstract: In a sensor system and a corresponding method for image capture of an object, an imaging sensor is arranged in a recording area of an optical sensor, the recording area being defined for the object, in such a way as to be essentially stationary relative to said object. By means of an evaluation unit, relative movements between the imaging sensor and the object can be derived from the recorded image data of the optical sensor, and a three-dimensional object image can be reconstructed from the imaging data as a function of the relative movements. When determining the relative movements, it is in particular possible as well to detect relative movements caused by the object's own motion which can be taken into account when reconstructing the object image. As a result, a high image quality of the object image is achieved.

Abstract: An apparatus for supplying an RFID component with energy includes an antenna and an energy store. The energy store stores energy induced into the antenna by an alternating electromagnetic field during a first time interval. In addition, the energy store supplies the RFID component with stored energy in order to maintain its functionality during a later, second time interval if an energy induced by an alternating electromagnetic field during the later, second time interval is not sufficient for supplying the RFID component.

Abstract: A color value for an optical fiber of a fiberscope can be generated on the basis of the intensity values of a plurality of sensor elements of a sensor element arrangement that are sensitive to one spectral region each from a set of sensor spectral regions, if calibration values are provided for each of the spectral regions associated with the optical fiber. The intensity values of all sensor elements of the respective spectral region that are illuminated by the light guide can be combined with the provided calibration values, in order to obtain the color value associated with the optical fiber, which reproduces the color of the light transported by the optical fiber.

Abstract: In a method for estimating a deviation between a free-running transmitter clock and a reference clock, at a receiver stationary with respect to a transmitter, a transmitter signal generated by the transmitter on the basis of the transmitter clock is received. On the basis of the reference clock, a time of arrival of the transmitter signal and a beat phase of the transmitter signals carrier is determined. On the basis of a clock error model, the time of arrival and the beat phase, the deviation between the transmitter clock and the reference clock is estimated. The clock error model is derived by fitting a correlation function of a stochastic model to a measured auto correlation function of the transmitter clock. Deviations for a plurality of transmitters may be estimated and the transmitters may be virtually synchronized based on the estimations.

Abstract: Images of an object, such as OCT scans of a human eye, can include distortions and data gaps due to relative motion of the object and the image acquisition device. Methods and systems for correction of such distortions and data gaps are described herein. Motion-corrected data is arrived at by applying three-dimensional transforms to input three-dimensional data sets that represent at least partially overlapping regions of the imaged object. The three dimensional transforms are computed based on an objective function that accounts for similarity between the transformed three-dimensional data sets and the estimated motion of the object relative to an imaging instrument. Methods and systems described herein advantageously eliminate the need for postulated assumptions and reliance on landmarks and are capable of filling data gaps, thereby producing high quality, undistorted images of objects subject to movement during imaging.
