1. An adapter for enabling a first type of optical oximeter probe to be utilized with an oximeter monitor that provides probe signals for use with a second type of optical oximeter probe, said adapter comprising:
- (a) a set of N signal inputs for receiving N input signals from an oximeter monitor for powering at least one light emitter;
(b) a set of M signal outputs for providing M output signals to an oximeter probe having said at least one light emitter configured to connect to M signal inputs, wherein M and N are different integers each of which is greater than 1;
(c) an active switch which actively connects said N inputs to said M outputs, thereby actively gating;
wherein at least one of the input signals functions as a control signal to actively control gating of said input signals.

Abstract
The present invention provides an adapter which actively connects a two terminal oximeter probe or monitor to a three terminal monitor or probe. This is done actively, with the alternating drive signals from the oximeter monitor providing a control signal for switching the adapter connections. The adapter connections are preferably made with diodes, transistors, or other active devices.
