摘要： The invention relates to an apparatus for measuring the heart rate and the respiration rate of one or more anesthetized rodent while monitoring and maintaining body temperature of at least one or more anesthetized rodent during diagnostic or surgical procedures. The apparatus includes a printed circuit board having four electrodes, two of which are injection electrodes and two of which are sensor electrodes. The heart rate is monitored through known electrocardiogram techniques, however, the respiration rate is monitored by injecting an electrical current across the chest of the rodent between two of the electrodes to determine impedance of the electrical current across the chest of the rodent. The impedance is carried by a respiration signal that is then graphically displayed to measure and, thus, monitor the respiration rate. The apparatus further includes the ability to maintain and monitor the body temperature of the rodent. Methods of monitoring the respiration rate of one or more anesthetized rodents during diagnostic or surgical procedures are also disclosed.

摘要： A method and apparatus is provided for automated control and positioning of a mandrel within a pipe during bending operations. Position detection is accomplished by means of a low frequency electromagnetic signal transmission from a coil placed in close proximity parallel to the pipe outer surface. This signal is detected by a pair of orthogonal receiving coils mounted on the mandrel in close proximity to the pipe inner surface. The phases of the received signals with respect to the transmitted signal and the ratio of the amplitudes of the two received signals is used to estimate the relative position of the transmitter and the receivers. Control of the mandrel along with transmission of reference phase information is accomplished via a high frequency direct sequence spread spectrum radio link between a computer console outside the pipe mounted on the bender and a computer unit mounted inside the pipe on the mandrel.
摘要翻译：提供了一种方法和装置，用于在弯曲操作期间自动控制和定位管内的心轴。位置检测是通过从靠近平行于管外表面放置的线圈的低频电磁信号传输来完成的。该信号由安装在心轴上的一对正交接收线圈紧邻管内表面检测。接收信号相对于发射信号的相位和两个接收信号的幅度比用于估计发射机和接收机的相对位置。芯轴的控制以及参考相位信息的传输是通过安装在弯曲机上的管道外部的计算机控制台与安装在心轴上的管道内的计算机单元之间的高频直接序列扩频无线电链路实现的。
