摘要： In an injection molding process, it can be difficult to detect, in real time, process control variables such as pressure and temperature. Traditional temperature detectors and pressure sensors can be difficult to place in or near a mold cavity. An example embodiment of the present invention includes a self-powered multivariate sensor and uses acoustic transmission. The sensor may employ an infra-red thermal detector and pressure sensor and transmit coded representations of measurements acoustically via a body of the mold. From the temperature and pressure, melt velocity and melt viscosity of a compound in the mold can be determined with a high degree of accuracy by a processor internal to or external from the sensor. The example embodiment maintains structural integrity of the mold, provides a wireless self-powered sensor, and makes available sensing of properties of the viscous compound to enable injection molded parts production at a success rate exceeding 90%.

摘要： Disclosed herein is a novel sensing technique, termed Multiple Excitation Capacitance Polling (MECaP), that improves the efficiency of Electrical Capacitance Tomography (ECT). Unlike traditional alternating current techniques, where excitation signal is applied to an electrode one at a time, MECaP involves simultaneously applying multiple excitation signals, in a progressively increasing fashion, to multiple electrodes on an ECT sensor. The received signals are filtered or otherwise decomposed (e.g., Fourier transformed) into different components, and the individual components are used to generate an image of the article or substance disposed between the electrodes. Because multiple capacitances can be simultaneously measured as a consequence, scanning with MECaP can significantly increase the image scanning speed. For example, scanning with MECaP may enable frames rates of tens of kHz for imaging dynamic processes such as engine combustion.
摘要翻译：本文公开了一种新颖的感测技术，称为多激发电容轮询（MECaP），其提高电容层析成像（ECT）的效率。与传统的交流技术不同，其中激发信号一次一个地施加到电极上，MECaP包括以逐渐增加的方式同时向ECT传感器上的多个电极施加多个激发信号。所接收的信号被过滤或以其他方式分解（例如，傅立叶变换）到不同的部件中，并且使用各个部件来产生设置在电极之间的物品或物质的图像。因为可以同时测量多个电容，所以用MECaP扫描可以显着提高图像扫描速度。例如，使用MECaP进行扫描可以使成像动态过程（如发动机燃烧）的数十kHz的帧速率。
