  • Patent number: 9454203
    Abstract: An information handling system is powered by a battery. In response to determining that a remaining amount of power within the battery has fallen below a first threshold, power consumption of the information handling system is reduced by reducing at least one non-critical operation of the information handling system, while maintaining at least one critical operation of the information handling system. After reducing the at least one non-critical operation, it is increased in response to determining that the remaining amount of power within the battery has risen above a second threshold.

    Abstract: A method and apparatus for estimating the true temperature of connate fluid within a subterranean geological formation is provided herein. The method includes generating a flow of connate fluid, measuring the temperature of the flow over time until the measured temperature reaches a limiting value termed the stabilized temperature. Multiple events of temperature sampling events can be conducted at different flow rates of the connate fluid. The stabilized temperature values can then be ascendingly organized based on the value of their respective flow rates. The limiting value reached by the stabilized temperatures is taken to be substantially equal to the actual temperature of the connate fluid residing within the subterranean formation.

In certain embodiments, one or more mobile collectors having mobility that is unpredictable to a wireless sensor network are deployed for use in accessing the wireless sensor network. Thus, rather than relying on an access technique having certainty designed therein with regard to the access of a wireless sensor network, certain embodiments utilize an access technique that relies on statistical probability for accessing the wireless sensor network. For instance, by deploying a plurality of mobile collectors that are operable for accessing a wireless sensor network, a statistical probability exists that at some point (or at various points in time) at least one of the mobile collectors will travel within range of the wireless sensor network to enable access thereof.
