摘要： A high frequency oscillatory ventilator for infants and adults using feedback control to maintain either the desired tidal volume or pressure delivered to the subject. The inspiratory to expiratory time ratio of the ventilator is variable. The ventilator corrects the measured pressure for arbitrarily-sized endotracheal tubes and calculates the actual pressure or tidal volume delivered to the subject. The ventilator also separates the source of the tidal volume oscillations from the patient circuit with a flexible membrane or diaphragm, allowing transmission of oscillating tidal volumes while blocking mean airway pressures. The patient circuit is flexible, but fabricated from low-compliance material to minimize the loss of tidal volume. The ventilator uses feedback control of the exhaust flow to maintain mean airway pressure in the presence of an independently controlled bias flow. Further, a respiratory impedance measurement system is built into or connected to the patient circuit which monitors changes in lung mechanics while the patient is connected to the high frequency ventilator without changing mean airway pressure or removing the patient from the ventilator.
摘要翻译：用于婴儿和成年人的高频振荡呼吸机，使用反馈控制来保持传递给受试者的所需潮气量或压力。呼吸机吸气与呼气时间的比值是可变的。呼吸机校正任意尺寸的气管插管的测量压力，并计算输送给受试者的实际压力或潮气量。呼吸机还通过柔性膜或隔膜将潮气量振荡源与患者回路分开，允许振荡潮气量的传播，同时阻止平均气道压力。患者电路是柔性的，但由低顺应性材料制成，以尽量减少潮气量的损失。呼吸机使用排气流的反馈控制来在存在独立控制的偏流的情况下维持平均气道压力。此外，呼吸阻抗测量系统内置或连接到患者电路，其在病人连接到高频呼吸机而不改变平均气道压力或从呼吸机移除患者时监测肺力学变化。

摘要： An apparatus and method for monitoring a reciprocating member of a reciprocating piston compressor is presented. The apparatus and method provide a means for measuring parameters of the reciprocating member, such as road load or cross-head temperature and the like, and wirelessly transmitting the data to a receiver. A mobile assembly is attached to a reciprocating member of the compressor, the mobile assembly having a sensor assembly, a wireless transmitter and a power generation assembly. The sensor assembly measures a parameter of the reciprocating member and generates a representative sensor signal. The wireless transmitter wirelessly transmits a corresponding data signal to a stationary assembly mounted nearby. The power assembly powers the transmitter and sensor assembly. The measured data is used, in conjunction with other measurements, such as a crankshaft encoder, to calculate the work performed by the compressor, the power used by the compressor and other information. The compressor utilization is then optimized based on the gathered information.

摘要： A crosslinked water-based gel, for example a gel plug in an underground rock formation or a pipeline, is broken by an enzyme and a substrate which is capable of being converted by the enzyme into an organic acid which breaks down the gel. The enzyme is allowed to catalyze the conversion of the substrate into the acid to cause the breakdown of the gel.

摘要： A computer-based system and method detects and specifies valve and ring leaks in reciprocating compressors of the type used in natural gas transmission networks. The system employs a method comprising the following steps. The cylinder pressure is measured as a function of cylinder volume to obtain a measured PV card. A predictive model then calculates a predicted PV card for the subject compressor cylinder without including effects of simulated leaks. The predicted PV card is them compared to the measured PV card. The nature and character of the differences between the measured and predicted PV cards indicates whether a leak in the subject compressor cylinder is a suction valve leak, a discharge valve leak, or a piston ring leak. The predictive model is then iterated with simulations of the indicated leak included until the resulting predicted PV card matches the actual measured PV card for the compressor cylinder. The final value of the leak parameters in the model required for the match indicate the nature and magnitude of a corresponding actual leak in the compressor cylinder. Other useful information such as the efficiency of the compressor system with and without the leak and the economic impact of the leak are also derived from the iterative match process.

摘要： A method of balancing combustion among cylinders of an internal combustion engine. For each cylinder, a normalized peak firing pressure is calculated as the ratio of its peak firing pressure to its combustion pressure. Each cylinder's normalized peak firing pressure is compared to a target value for normalized peak firing pressure. The fuel flow is adjusted to any cylinder whose normalized peak firing pressure is not substantially equal to the target value.
