摘要： An estimation device detects, with a detection unit, an electrical property between plural detection points in a conductive flexible material. An estimation unit uses the flexible material and a learning model to estimate the shape of an estimation target object based on the electrical property of the flexible material. The learning model is trained to use as learning data an electrical property that changes in a time series in response to deformation of the flexible material and shape information representing shapes, in the flexible material, of pressure stimuli that impart deformation to the flexible material and to receive the electrical property as input and to output the shape information.

摘要： According to the techniques herein, one or more sensors coupled to an aligner are used to sense one or more physical qualities of the aligner to determine whether the physical qualities indicate that the aligner material has relaxed and has, e.g., reduced the force systems applied to teeth and/or that the teeth movement for the stage has slowed down. The sensors may provide a signal that represents whether or not the physical qualities fall below a threshold value. A treatment plan may be modified if needed. These techniques have the potential to make treatment plans faster and more effective by speeding up some stages while making sure some, perhaps other, stages are implemented only after the teeth are near the appropriate position.

摘要： Strain sensors are attached to a workpiece, and resistance values of the strain sensors are measured with time while cutting the workpiece with a milling cutting machine. A power spectrum in a frequency domain is obtained by Fourier-transforming the resistance values measured with time. A power peak is found in the power spectrum to be outputted as a magnitude of vibration occurring during machining the workpiece. By attaching a strain sensor to a stamper of a plastic working machine, a resistance value of the strain sensor is measured while pressing a workpiece on a die with the stamper. A magnitude of the strain corresponding to the measured resistance value is used to obtain a corresponding plastic working force. By attaching the strain sensor directly to the workpiece, it is possible to monitor the state of the plastic working and/or cutting process of the workpiece with high precision at low cost.

摘要： A device for detecting wear of a wear member composed of electrically resistive material. The wear member comprises at least two electrodes separated from each other, where each electrode overlies, or is embedded in, an outer surface of the electrically resistive material. One of the electrodes is connected to a resistor at a measurement node to form a resistive voltage divider. A voltage measurement device measures a change in voltage at the measurement node, where the change is voltage is indicative of the degree of removal of resistive material from a face of the wear member and where the change in voltage is continuously variable and not limited to discrete wear levels.
