Abstract: A mobile health device for providing a health service includes a health sensor that monitors values of a health metric of a person, a power control component that controls supplying power to the health sensor and to other components of the mobile health device, and a motion sensor, coupled to the power control component, that detects a motion of the mobile health device, where the motion sensor sends a communication to the power control component in response to detection of the motion to activate the other components of the mobile health device. The communication may specify a duration of the motion, and the power control component may activate at least one of the other components of the mobile health device based on the duration. The other components may include a network interface component that communicates with a remotely coupled device to provide the health service to the person.

Abstract: A mobile health device includes a health sensor that monitors values of health metrics of a person where performance of the health sensor is affected by temperature. An internal temperature sensor monitors a temperature of an internal region of the mobile health device. A thermal control component controls a thermal output of components of the mobile health device based on the temperature of the internal region. The mobile health device may also include a plurality of processing cores that execute instructions where the thermal control component reduces a collective thermal output of the plurality of processing cores by reducing a number of the plurality of the processing cores that actively execute instructions. The thermal control component may reduce a thermal output of the processing core by reducing a frequency of instruction execution of the processing core. A thermal buffer may be used.

Abstract: The invention uses expiration notification events and object references to indicate when a software object has expired. Expiration notification events are occurrences that indicate when corresponding object references and dependent references should be removed. Object references and dependent references are references to objects within the computer memory. Using the object management methods of the Expiration Informer, the object references are stored in a table according to the objects' expiration time. Upon expiration, the managed object is removed from the table and stored in an expiration event. The expiration event is sent to the requester at which time the Expiration Informer has removed any reference to the object. The invention is capable of managing objects is a distributed computing environment. The invention executes these capabilities in an extremely efficient manner adding minimal CPU overhead when managing thousands of time-based objects.
