摘要： A sensor apparatus for detecting both ferrous and non-ferrous particles in a fluid including a housing adapted for insertion into a fluid line, the housing having a collection cavity formed therewithin for trapping and holding metallic particles which are suspended in the fluid as the fluid passes through the sensor. A first coil wound below the collection cavity and a second coil wound about the collection cavity, the inductance of the first coil being responsive to the temperature of the fluid passing through the sensor and the inductance of the second coil being responsive to the ferrous and non-ferrous particle accumulation within the collection cavity. An electromagnetic coil is spaced above the second coil to attract ferrous particles away from the vicinity of the second coil. Based upon eddy current principles and because eddy currents are a function of material conductivity, a first energization of the second coil generates a signal indicative of the total ferrous and non-ferrous particle accumulation within the collection cavity and a second energization of the second coil with the electromagnetic coil likewise energized generates a signal indicative of just the non-ferrous particle accumulation within the collection cavity. A microprocessor coupled to the coils calculates the percentage of ferrous and non-ferrous particles in the collection cavity and outputs such information for diagnostic, prognostic and trend analysis purposes.
摘要翻译：一种传感器装置，用于检测包括适于插入流体管线的壳体的流体中的黑色和有色金属颗粒，所述壳体具有形成在其中的收集腔，用于捕获和保持当流体流过时悬浮在流体中的金属颗粒通过传感器。卷绕在收集腔下方的第一线圈和围绕收集腔卷绕的第二线圈，第一线圈的电感响应于流过传感器的流体的温度，并且第二线圈的电感响应于铁和非线性收集腔内的有色颗粒积聚。电磁线圈在第二线圈上方间隔开以吸引铁质颗粒离开第二线圈附近。基于涡流原理并且由于涡流是材料导电性的函数，所以第二线圈的第一通电产生一个信号，该信号表示集合腔内的总铁含量和有色金属颗粒积累，第二线圈的第二通电类似地通电的电磁线圈产生指示仅在收集腔内积聚有色金属的信号的信号。耦合到线圈的微处理器计算收集腔中的亚铁和有色金属颗粒的百分比，并输出这样的信息用于诊断，预测和趋势分析目的。

摘要： In one aspect of the invention, an apparatus for sensing a plurality of operating parameters of an internal combustion engine is disclosed. An energy source supplies electrical energy to the pistons, whereby each piston forms a variable capacitor with the engine housing. The capacitance value of each variable capacitor changes as a function of the relative position of the piston to the housing. An oscillator circuit produces a capacitive signal that is indicative of the capacitance value of each variable capacitor. A microprocessor receives the capacitive signal and responsively determines one of a plurality of operating parameters of the engine.

摘要： Automatic starting fluid injection systems are useful, for example, to aid in the cold-starting of diesel engines. In the subject invention, a microprocessor under software control is used to controllably inject starting fluid into an engine passageway, such as an intake manifold. During engine cranking, the microprocessor delivers an injection signal to a fluid delivery system to effect starting fluid injection into the engine passageway. When the engine starts, a subsequent injection time is calculated based on the sensed engine temperature. The microprocessor continues to deliver the injection signal to the fluid delivery system during the subsequent injection time.

摘要： A piston position sensing system in which tabulated resonance width related information is stored in a form correlated with piston travel so that measured resonance width information can be compared with the stored information in determining piston position and compensation for the velocity of the piston is provided by correction for a time difference in serial sensing between the initial and the following extremes of a resonance signal as the piston moves. the compensation is developed from velocity information identified through previous and current processing cycles which assures reliability in detection of the subsequently sensed portion of the resonance signal envelope and enhanced sensitivity and accuracy through automatic application incrementally in a dynamic gain adjustment of the sensing system.
