摘要： Approaches are disclosed for generating high voltage sinusoidal signals whose output voltage can be adjusted rapidly, without introducing high frequency artifacts on the output. When these approaches are used, stronger electric fields can be applied to the tumor for a higher percentage of time, which can increase the efficacy of TTFields therapy. In some embodiments, this is accomplished by preventing adjustments to a DC power source during times when the output of that DC power source is powering the output signal. In some embodiments, this is accomplished by synchronizing the operation of an AC voltage generator and an electronic switch that is connected to the output of the AC voltage generator.

摘要： An apparatus for calibrating a time-interleaved analog-to-digital converter including a plurality of time-interleaved analog-to-digital converter circuits is provided. The apparatus includes an analog signal generation circuit configured to generate an analog calibration signal based on a digital calibration signal representing one or more digital data sequences for calibration. The analog calibration signal is a wideband signal. Further, the apparatus includes a coupling circuit configured to controllably couple an input node of the time-interleaved analog-to-digital converter to either the analog signal generation circuit or to a node capable of providing an analog signal for digitization.

摘要： Signal processing devices and methods estimate transforms between signals using a least squares technique. From a seed set of transform candidates, a direct least squares method applies a seed transform candidate to a reference signal and then measures correlation between the transformed reference signal and a suspect signal. For each candidate, update coordinates of reference signal features are identified in the suspect signal and provided as input to a least squares method to compute an update to the transform candidate. The method iterates so long as the update of the transform provides a better correlation. At the end of the process, the method identifies a transform or set of top transforms based on a further analysis of correlation, as well as other results.

摘要： A signal generator (100, 1100, 1300) generates an output signal (S_OUT) according to an oscillating signal (XO_IN). The signal generator (100, 1100, 1300) has a plurality of edge sampling circuits (102_1-102_N) and an edge combining circuit (104, 600, 800, 1000). Each of the edge sampling circuits (102_1-102_N) receives the oscillating signal (XO_IN), samples the oscillating signal (XO_IN) to obtain at least one of a rising edge and a falling edge in one cycle of the oscillating signal (XO_IN), and outputs a sampled signal (S1-SN) using the at least one of the rising edge and the falling edge. The edge combining circuit (104, 600, 800, 1000) combines a plurality of sampled signals (S1-SN) generated by the edge sampling circuits (102_1-102_N), respectively, to generate the output signal (S_OUT).

摘要： A device is provided for computing a function value of a function F. The device includes a memory, a truncator unit, a selector unit, and an evaluator unit. The memory contains a look-up table comprising a set of entries, each entry having associated with it a domain and an approximation function for approximating F on the associated domain. The truncator unit is arranged to truncate or round a first value X1 to generate a second value X2. The selector unit is arranged to select an entry of the lookup-table according to the second value X2, thus selecting the approximation function that is associated with the selected entry. The evaluator unit is arranged to determine the function value of the selected approximation function at the first value X1.
