Connector switch
First Claim
1. An interconnection between a noninvasive optical sensor and a monitor configured to receive one or more signals from said sensor indicative of light attenuated by body tissue, the monitor also configured to determine measurements for one or more physiological parameters based on the received one or more signals, the interconnection comprising:
- a cable having a plurality of conductors providing electrical communication between a sensor connector and a monitor connector;
an information element readable by said monitor to determine information about a type of said sensor and to configure said monitor in its determination of said one or more physiological parameters based on said type, and mounted in one of said sensor connector, said monitor connector and said cable; and
a switch mounted in said sensor connector responsive to said sensor connecting to and disconnecting from said sensor connector so as to alter the readability of said information element.

Abstract
An interconnection between a sensor and a monitor has a cable, an information element and a switch. The cable has conductors providing electrical communication between a sensor connector and a monitor connector. The information element is readable by the monitor and mounted in the sensor connector, the monitor connector or the cable. A switch is mounted in the sensor connector and is responsive to the sensor connecting to and disconnecting from the sensor connector so as to alter the readability of said information element.

5. An interconnection method comprising the steps of:
-
providing a cable configured to communicate drive signals from a physiological parameter monitor to a noninvasive optical sensor capable of outputting a signal indicative of light attenuated by body tissue, and to communicate physiological signals from said sensor to said monitor; associating an information element with said cable, said information element capable of conveying information regarding said sensor to said monitor; and actuating a switch in response to said sensor connecting and disconnecting to said cable so as to render said information element readable and unreadable by said monitor, respectively. - View Dependent Claims (6, 7, 8)
