Systems and methods described herein leverage dependence relationships between sensor readings to facilitate rapid detection of erroneous sensor readings and rapid response times when accurate sensor readings indicate events that call for remedial action. When a target sensor reports a questionable sensor reading, systems described herein can query additional sensors whose readings share expected dependence relationships with readings from the target sensor. Systems described herein determine whether the questionable sensor reading is trustworthy based on the expected dependence relationships and additional sensor readings received from the additional sensors. If the questionable sensor reading is trustworthy, the system can trigger appropriate remedial action and increase query rates for the additional sensors (and the target sensor) to monitor an underlying event more closely. If the questionable reading is not trustworthy, the system can trigger appropriate remedial action (e.g., by deactivating the sensor or sending an alert to an administrator).

Sensor reading verification and query rate adjustment based on readings from associated sensors

Systems and methods described herein reduce contention on shared buses through which multiple sensors send sensor readings to a computing destination by allowing different query rates for each sensor and dynamically adjusting the query rate for each sensor based on the readings that sensor reports. A first query is sent to a sensor via a bus to request a current sensor reading from the sensor. In response to the first query, the sensor sends the current sensor reading via a bus. A function of the current sensor reading, a predefined time range, and a predefined reading-value range is evaluated to determine a time interval between the first query and a second query to be sent to the sensor. When the amount of time elapsed since the first query was sent matches the time interval, the second query is sent to the sensor via the bus to request an updated sensor reading.

Systems and methods for I/O prioritization in nvme-compliant storage devices

A method and system for recovering embedded system memory contained within an embedded system includes a software image in embedded system memory and identifying unneeded software features in the software image; identifying memory portions containing the unneeded software features; and reallocating the memory portions containing the unneeded features.
