摘要： A distance between a radiation source and a detector is first set to a first distance and the number of pulses of a .gamma.-ray is detected. Then, the distance between the radiation source and the detector is set to a second distance different from the first distance and the number of .gamma.-ray pulses is detected. A density .rho. of a sample is finally calculated on the basis of a ratio of the two detection pulse numbers which were detected. The radiation source is set on the surface of the sample or in the sample. The sample detector is set on the sample surface. Fundamentally, one radiation source and two detectors are used. In the case of using one radiation source and one detector, either one of them is moved and the number of pulses is detected twice.

摘要： The present invention provides methods for detecting an abnormal condition of a blood pump system based on the power consumption of the pump actuator. By plotting differentiated power consumption of the pump actuator over time against the power consumption, a plot pattern is obtained. A change of the plot pattern area and/or a movement of the plot pattern will indicate a change in condition of the pump. A Heart Pump Area (HPA) index may be established which corresponds to the changing area of the plot pattern over time. A Heart Pump Position (HPP) index may be established which corresponds to the changing position of the plot pattern over time (e.g., corresponding to the distance the plot pattern has moved). By plotting the HPA index against the HPP index, changes in the condition of the pump can be monitored and any abnormal condition of the pump can be detected.
摘要翻译：本发明提供了基于泵致动器的功率消耗来检测血液泵系统的异常状况的方法。通过绘制泵致动器的不同功耗随着时间的推移消耗功率，可获得绘图模式。曲线图区域的变化和/或曲线图的移动将指示泵状态的变化。可以建立心脏泵面积（HPA）指数，其对应于随时间变化的情节区域的变化。可以建立心泵位置（HPP）索引，其对应于随时间变化的情节图案的位置（例如，对应于绘图模式移动的距离）。通过绘制HPA指数与HPP指数的关系，可以监测泵状态的变化，并检测出泵的任何异常情况。

摘要： The present invention provides an inflow cannula tip that is shaped to prevent suction with the ventricular wall and adapted to prevent platelet adhesion. In particular, the inlet portion of the cannula tip comprises two projections extending from the cylindrical body of the cannula tip with gaps between the projections. The projections may have beveled edges. The inlet portion of the cannula tip can accept blood flow from either the gaps in the side or from the bottom of the tip. Even if the edge of the cannula tip is close to or even touching ventricle wall, a suction condition will not result, as blood is allowed to flow through the gaps between the projections.
摘要翻译：本发明提供一种流入套管末端，其形状适于防止与心室壁的吸引并适于防止血小板粘附。特别地，套管尖端的入口部分包括从插管尖端的圆柱体延伸的两个突起，其中突出部之间具有间隙。突起可以具有斜边。套管尖端的入口部分可接受来自尖端的侧面或底部的间隙的血液流动。即使插管尖端的边缘接近或甚至接触心室壁，由于允许血液流过突起之间的间隙，因此不会产生抽吸条件。

摘要： An object of the invention is to provide a small and low-cost switching power supply unit with a backup function in which a proper circuit construction can be selected by simple method when it is necessary to compensate for the instantaneous drop or power failure and a disk array system having the switching power supply unit. To accomplish the object, a backup unit which can insert and pull out its hot line into a switching power supply unit casing and has a secondary battery and its state monitoring/control unit is built in the unit, and proper charge/discharge management of the secondary battery can be made. When the backup unit is unnecessary, a backup unit formed by a plurality of capacitors whose hot lines can be similarly inserted and pulled out can be built in an enclosing space of the backup unit.
