摘要： The gas mixing apparatus provides the components of a breathing gas for mixing at approximately ambient atmospheric pressure, and regulates the pressure of a selected gas to approximately ambient atmospheric pressure for mixing with air at ambient atmospheric pressure. The gas mixing apparatus includes a piston disposed within a pump chamber. A flow limiting inlet controls introduction of a first selected gas such as oxygen for mixing with a second selected gas such as air. The pressure of the first selected gas is limited to an acceptable maximum pressure, so that even if a valve for admitting the first selected gas for mixing at ambient pressure fails, breathing gas will not be provided at an excessive pressure. A demand valve is alternatively provided for reducing the pressure of the first selected gas supplied before mixing, but a pressure sensor is also provided downstream of the demand valve for detecting failure of the demand valve, to shut off the supply of the first selected gas to prevent overpressurization.

摘要： A calibration method and apparatus capable of being calibrated according to the method that allows a remote sensor to be transferred from analyzing instrument to analyzing instrument within a group of analyzing instruments without the need to recalibrate. The device includes a separate memory capability associated with the sensor as well as each instrument while the method requires the use of an arbitrarily selected sensor to initially be transferred from instrument to instrument, while being subjected to the same calibration standards in order to generate calibration data for entry into each instrument's memory. With such data entered in the instruments' memories, any remote sensor, calibrated on any one instrument and having such calibration data stored in its own memory, can then readily be interconnected to any instrument of the group to immediately yield accurate results.

摘要： Output signals from a set of Faraday loops located in a common plane are combined selectively to simulate the output signals from a set of mutually orthogonal antennas. This arrangement and use of Faraday loops are especially suitable in a hospital environment for monitoring patients. Because of the availability of output signals from a set of equivalent orthogonal antennas, any danger of a gap in the monitoring of the patient is greatly minimized; the patient can be monitored regardless of the changing orientation of the patient with regards to the monitoring antennas.
