System for adjusting power employed by a medical device
First Claim
1. A system for adjusting power employed by a medical device incorporating light emitting devices and being used for measuring patient medical parameters, comprising:
- a plurality of light emitting devices;
a power unit coupled to said light emitting devices for powering said light emitting devices responsive to respective control signals for determining power applied to said light emitting devices; and
a control unit for providing said control signals and being coupled to the power unit, said control signals intermittently turning off at least one of said plurality of light emitting devices in a power save mode in response to a determination that a patient medical parameter value measured by said medical device, using an active light emitting device of said plurality of light emitting devices, remains at a safe level,wherein, in said power save mode, at least one of said plurality of light emitting devices is in an active state.

Abstract
A system for adjusting power employed by a medical device incorporating light emitting devices and being used for measuring patient medical parameters, includes a plurality of light emitting devices. A power unit is coupled to the light emitting devices and powers the light emitting devices responsive to respective control signals which determine power to be applied to the light emitting devices. A control unit for provides the control signals and is coupled to the power unit. The control signals intermittently turn off at least one of the plurality of light emitting devices in a power save mode in response to a determination that a patient medical parameter value measured by the medical device, using an active light emitting device of the plurality of light emitting devices, is at a safe level.
