  • System for Adjusting Power Employed by a Medical Device
    Publication number: 20120116193
    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.

  • Patient monitoring and alarm processing system and user interface
    Patent number: 7981032
    Abstract: Some embodiments of the invention provide a system to monitor a patient. In some aspects, a signal representing a value of a physiological parameter is received from a monitoring device. The received value is a value that caused the monitoring device to trigger an alarm associated with the psychological parameter. A notification is determined based on the received signal and on a second signal that represents a value of a second physiological parameter. The notification is then presented to an operator.

  • Power conserving adaptive control system for generating signal in portable medical devices
    Patent number: 6863652
    Abstract: A system and method for adjusting power employed by a light emitting device used for medical applications, such as measurement of patient parameter. A system or device includes a light emitting device, a power unit coupled to the light emitting device for powering the light emitting device and responsive to a control signal for adjusting power applied to the light emitting device, and a control unit for providing the control signal and coupled to the power unit, the control signal being determined in response to a characteristic of a signal associated with a physiological parameter measured using light produced by the light emitting device.
