摘要： The differential amplifier circuit employs a pair of amplifier legs of similar electrical characteristics. Input signals are applied across the two legs at the base of a pair of transistors forming a first amplification stage. A further pair of output transistors are interrelated with the input amplification stage, and interconnecting the output transistors are constant current devices. Biasing voltage is applied via the constant current devices whereby common-mode signals are denied a path to the amplifier input and are effectively cancelled out to provide an output for the differential amplifier that is substantially purely related to the information signal. Another aspect is the provision of an input isolation circuit for eliminating commonmode return paths where the differential amplifier has internal voltage bias.
摘要翻译：差分放大器电路采用一对具有类似电特性的放大器支脚。输入信号跨越形成第一放大级的一对晶体管的基极两端施加。另一对输出晶体管与输入放大级相互关联，并且输出晶体管的互连是恒流器件。通过恒流器件施加偏置电压，从而使共模信号被拒绝到放大器输入的路径，并且被有效地抵消以提供基本上纯粹与信息信号相关的差分放大器的输出。另一方面是提供用于消除差分放大器具有内部电压偏置的共模返回路径的输入隔离电路。

摘要： An improved electromagnet for blood flowmeters and the like is made by filling the open central portion of a magnetizing coil with a mixture of iron powder suspended in a quick-hardening epoxy resin. The mixture is thereafter heated and cured to form an electrically nonconductive magnetic core.

摘要： A needle or catheter is received within a region of the body at which fluid pressure is to be measured. At its external end, the needle/catheter is connected to a chamber which also includes a strain-gage sensor. A saline solution is supplied to the chamber and internal parts of the needle/catheter during pressure measurement via a conduit passing through parts of the straingage sensor assembly. The conduit terminates at a special orifice and channel on the surface wall of the sensor assembly to provide a perfusing of the chamber and inner parts of the needle/catheter at a very slow rate and with negligible back pressure.

摘要： PULSE GENERATING AND SHAPING CIRCUITS GENERATE A COMOSITE OUTPUT SIGNAL SIMULATING AN ECG SIGNAL FOR DISPLAY ON CATHODE-RAY PRESENTATION EQUIPMENT. THE CIRCUITS ARE SELECTIVELY CONTROLLABLE TO PROVIDE THE QRS, P AND T WAVES OF INDIVIDUALLY PRESCRIBED AMPLITUDES AND VARIABLE RELATIVE LOCATIONS ALONG THE X-AXIS. THE QRS WAVE MAY BE MADE TO EXTEND EITHER POSITIVELY IN THE Y DIRECTION, OR INVERTED TO EXTEND NEGATIVELY. A FURTHER ASPECT IS THE PROVISION OF ADDITIONAL PULSE SIGNAL GENERATING CIRCUITRY FOR PRODUCING A PULSE TRAIN REPRESENTTIVE OF BLOOD PRESSURE AS MEASURED WITHIN THE AORTA.
