    • The present invention provides a memory chip for use in an oximeter sensor, or an associated adapter or connector circuit. The memory chip allows the storing of different data to provide enhanced capabilities for the oximeter sensor. In addition to providing unique data to store in such a memory, the present invention describes unique uses of data stored in such a memory. The data stored in the memory chip includes data that can be used by an oximeter to determine if the sensor is adequately attached to the patient, data that indicates sensor assembly characteristics that can be used to correct for variations in optical efficiency, data that can provide compensation for infrared wavelength shifts caused by optical fiber, data relating to additional LEDs in the sensor, data indicating the last time the sensor was moved or disconnected, and data indicating whether the sensor is isolated.
    • 本发明提供了一种用于血氧计传感器或相关联的适配器或连接器电路的存储芯片。 存储芯片允许存储不同的数据以提供用于血氧计传感器的增强功能。 除了提供存储在这样的存储器中的唯一数据之外,本发明描述了存储在这种存储器中的数据的独特用途。 存储在存储器芯片中的数据包括可以由血氧计使用以确定传感器是否被充分地附接到患者的数据,指示可用于校正光学效率变化的传感器组件特性的数据,可以提供的数据 对由光纤引起的红外波长偏移的补偿,与传感器中的附加LED相关的数据,表示上一次传感器被移动或断开的数据以及指示传感器是否被隔离的数据。
