A non-volatile solid-state storage subsystem, such as a non-volatile memory device, maintains usage statistics reflective of the wear state, and thus the remaining useful life, of the subsystem's memory array. A host system reads the usage statistics information, or data derived therefrom, from the subsystem to evaluate the subsystem's remaining life expectancy. The host system may use this information for various purposes, such as to (a) display or report information regarding the remaining life of the subsystem; (b) adjust the frequency with which data is written to the subsystem; and / or (c) select the type(s) of data written to the subsystem.

A method and system for detecting and predicting air filter condition for an air handling system operates by determining a system resistance to air flow. The system resistance is utilized to determine a detection statistic indicative of current filter condition and to predict remaining life of the air filter. The system resistance is determined using models that approximate the expected operation of the air handling system. The approximation is then compared to actual values to obtain a difference. Once the difference between the approximated value exceeds a threshold value, an alarm is initiated that is indicative of system resistance. The remaining air filter life is then determined by using historically gathered data, or by using a known degradation rate of the air filter. Once the remaining life of the air filter is estimated, replacement can be scheduled that would coincide with other maintenance.

A storage apparatus is provided with a plurality of nonvolatile semiconductor storage media and a storage controller that is a controller that is coupled to the plurality of semiconductor storage media. The storage controller identifies a first semiconductor storage unit that is at least one semiconductor storage media and a second semiconductor storage unit that is at least one semiconductor storage media and that is provided with a remaining length of life shorter than that of the first semiconductor storage unit based on the remaining life length information that has been acquired. The storage controller moreover identifies a first logical storage region for the first semiconductor storage unit and a second logical storage region that is provided with a write load higher than that of the first logical storage region for the second semiconductor storage unit based on the statistics information that indicates the statistics that is related to a write for every logical storage region. The storage controller reads data from the first logical storage region and the second logical storage region, and writes data that has been read from the first logical storage region to the second logical storage region and / or writes data that has been read from the second logical storage region to the first logical storage region.

A system and method for determining a remaining life estimate of the remaining battery life of a battery of an implantable medical device (IMD). The IMD battery preferably exhibits a highly reproducible monotonically decreasing discharge curve. The estimated remaining life estimates are derived by periodically measuring battery voltage, and estimating the estimated past current drain of the IMD comprising an average of the sum of the quiescent current drain and therapy delivery current drain, and determining the estimated remaining longevity from the measured voltage and the estimated past current drain.

A method to reduce uncertainty bounds of predicting a remaining life of a probe using a set of diverse models is disclosed. The method includes generating an estimated remaining life output by each model of the set of diverse models, aggregating each of the respective estimated remaining life outputs via a fusion model, and in response to the aggregating, predicting the remaining life, the predicting having reduced uncertainty bounds based on the aggregating. The method further includes generating a signal corresponding to the predicted remaining life of the probe.
