摘要： A device for directly measuring a person's respiratory exchange ratio (RER) utilizes a Zn-air battery cell and a constant current load circuit as an O2 pump capable of drawing oxygen from expired air. A thermistor located in the flow path forms a leg of a bridge circuit whose output is proportional to oxygen concentration in the expired air and, therefore, to oxygen uptake. The thermistor flowmeter circuit utilizes the thermal conductivity differences between O2 and CO2 to provide a measure at the relative ratio of the two gases present.

摘要： A method of calibrating a metabolic analyzer incorporating an oxygen analyzer and a NDIR carbon dioxide analyzer in the field that does not require the use of gas cylinders containing gases of known concentration is described. In calibrating the CO2 detector, at the time of factory setup, the detector output for a gas of a known concentration is measured and stored in the memory of the metabolic analyzer's microprocessor, as is the detector output voltage when the IR source is dimmed by a known percentage. Subsequently, in the field, CO2 levels in ambient air and cell pressure are measured at two different flow rates through the sample chamber and the IR source is again dimmed by the same percentage as had been used at the time of factory setup. Based upon the resulting readings, both the zeroing and span adjustment factors can be computed.

摘要： A portable apparatus for measuring the thoracic lung volume of a patient without enclosing the patient in a sealed chamber, comprising first and second impedance belts, a flow meter, shutter and a microprocessor-based controller. The flow meter includes pressure transducers for measuring the change in volume and pressure as the patient respires therethrough. The change in thoracic cage volume of the patient's lungs is directly correlated with the change of impedance in the belts. The thoracic lung volume is then determined from a measured barometric pressure, the measured change in pressure and the measured volume change in the thoracic cage volume utilizing a correction factor to determine the thoracic cage volume.

摘要： A simulated magazine useful to provide for simulated firing of a firearm includes a cycling lever arm which is depressed once every time the firearm is cycled; a linearly shaped counting plunger; a plunger spring biasing the plunger in an upward position; and a spring assembly connected to the cycling lever arm and acting upon the plunger. Depression of the cycling lever arm causes the plunger to move incrementally upward. When the plunger is in a fully up state, a slide catch trigger extends upward from the magazine, the slide catch trigger causing a slide of the firearm to remain in a back, open state.

摘要： A pulmonary diagnostic apparatus includes a personal computer including a memory for storing expected values, each representing a predicted normal level for a pulmonary function. A parameter limit file stores abnormality limits, each related to one of the expected values. A configuration file contains a plurality of degree of severity labels and numerical breakpoints between severity degrees. Finally, a statement data file contains a plurality of textual statements concerning lung functions and diseases or conditions. The three files are operatively associated with the computer. Lung function measuring equipment also is connected to the computer, whereby measured values are compared with the expected values. Based on the comparison, the computer generates an output identifying certain measured values as abnormal, and the degree of abnormality. Also, appropriate statements from the statement data file are generated as output, based upon the comparison. By selectively editing the parameter limit, configuration and statement files, the operator can cause the computer to generate an output corresponding to the operator's preferred analytical approach and syntax.

摘要： A rectangular sheet of flexible and resilient material such as plastic with notches at the midpoint of its sides. The size of the sheet and notches allow the insert to be placed into and located by a cell of a chain link fence. Notches fit around the wire crossovers of the chain link fence and locate the insert at the mid-plane of the fence. The corners of the insert extend into adjoining cells. Adjoining inserts overlap to provide complete visual privacy. The tile-like nature of the inserts allows great flexibility in arrangements and colors to provide visual privacy, decoration, words, logos, or signage.

摘要： A method for prescribing an exercise regimen for a particular subject to either maximize cardiovascular performance or to lose weight involves the use of a microprocessor-based cardiopulmonary exercise system to measure oxygen uptake and carbon dioxide production on a breath-by-breath basis. These measured quantities are used to calculate energy expenditure and a subject's respiratory exchange ratio from which a fat metabolization curve can be plotted. By examining the length of a plateau in the curve where the fat substrate utilization is maximized, and noting the average heart rate in this zone, a target heart rate for optimal weight loss is arrived at. If the goal of the exercise is cardiovascular improvement, the anaerobic threshold can readily be determined as the midpoint between maximal fat utilization and the maximum acceleration towards the point where the respiratory exchange ratio becomes equal to 1 or the fat metabolism goes to 0. By noting the average heart rate at the anaerobic threshold, a target heart rate for optimizing cardiovascular fitness may be arrived at.
摘要翻译：用于规定特定受试者的运动方案以最大化心血管性能或减肥的方法涉及使用基于微处理器的心肺运动系统来测量吸气和二氧化碳在呼吸基础上的产生。这些测量量用于计算能量消耗和受试者的呼吸交换比例，从中可以绘制脂肪代谢曲线。通过检查脂肪底物利用率最大化的曲线中的平台长度，并注意到该区域的平均心率，达到最佳体重减轻的目标心率。如果运动的目标是心血管改善，则厌氧阈值可以容易地被确定为最大脂肪利用率与呼吸交换比等于1或脂肪代谢变为0的点的最大加速度之间的中点。通过注意可以达到无氧阈值下的平均心率，用于优化心血管健康的目标心率。
