摘要： A method comprises the steps: A receiving (505, 510) a three-dimensional (3D) solid part model (304, 402) and an associated 3D solid blank (200, 302, 404); B defining (515) an initial in-process workpiece - in the following denoted by IPW - to be the same as the 3D solid blank; C defining (520) a cut volume in-process feature (202, 204, 306, 308, 408) to be removed from the IPW; D calculating an updated IPW by removing (530) the cut volume in-process feature (202, 204, 306, 308, 408) from the IPW; E if the IPW is not equal to the solid part model (304, 402) o repeating steps C and D; F storing (540) the updated IPW with the removed cut volume in-process feature in (202, 204, 306, 308, 404, 408) the data processing system (100). Advantageous embodiments of this method allow users to easily define CAM operations that reference IPW-aware 3D solid cut volumes as their volumetric containment and don't require manual definition of two-dimensional (2D) boundaries

摘要： Disclosed are a sensor interface device and an amplifier used in a sensor system. The sensor interface device in one implementation has a first chopper configured to shift input signals of the sensor system from a baseband frequency to a first frequency, an instrumentation amplifier configured to amplify the shifted signals, a bandpass Delta-Sigma modulator configured to digitize the amplified signals, and a second chopper configured to shift the digitized signals from the a first frequency back to the baseband frequency. The instrumentation amplifier removes the DC offset generated from the first chopper and therefore all sources of DC offset are eliminated in this interface device without bandwidth limitation.

摘要： Disclosed are a device and a method for calibrating a frequency of a transponder applicable to an RFID system. The device may comprises: a pulse generating unit configured to generate a sequence of pulses based on a PIE symbol sequence from an interrogator of the RFID system; a counting unit configured to count clock cycles of a clock signal based on the generated pulses, wherein the transponder operates based on the clock signal; and a calibrating unit configured to calibrate a frequency of the clock signal towards a target frequency based on a comparison of the counted number of clock cycles with a reference number associated with the target frequency.
