Abstract: A method and apparatus for managing power used by a computer system. User input relating to the power for a group of objects is received. A system description is sent to a user when the user input requests the system description for the group of the objects. The system description describes the group of the objects in the computer system with a level of detail based on a role of the user. Attributes are associated with the objects and the attributes for the objects are selected by at least one of measurement attributes or control attributes. A group of the control attributes for the group of the objects is set to control the power used by the group of the objects using application programming interfaces to the group of objects when the user input requests changes to the power used by the group of the objects.

Abstract: To compensate for the poor signal-to-noise ratio when transforming a patient tracheal sound signal into a respiration flow signal, the transformed signal is used when the sound signal is above a threshold, and interpolated values are used when the sound signal is below the threshold. A volume of breath signal is reliably obtained. Respiration start/stop is detected either by analyzing the sound signal or by physical measurement of the patient. A wearable device incorporating the sound signal processing method can provide an immediate indication or alarm when the volume of breath signal indicates a condition requiring medical attention.
