Abstract: A system for monitoring a fan used to cool equipment includes memory storing controller-executable instructions, and a controller configured to execute the instructions, which cause the controller to operate a fan, perform a deceleration test on the fan to obtain deceleration test data, calculate a variance of the deceleration test data, make a determination that the fan is susceptible to imminent failure based on the variance, and generate a signal for the equipment to enter a low-heat producing mode based on the determination.

Abstract: Systems and methods of intrusion detection into a rack enclosure are disclosed. An example method may include, extracting a projected light terminator image from a captured image, performing image correction operations on the projected light terminator image, processing the projected light terminator image utilizing image processing operations to determine a corrected projected light terminator image, determining a collection of image segments based on the corrected projected light terminator image, establishing one or more baseline image metrics of the collection of the image segments, evaluating the one or more baseline image metrics for changes with operational image segment characteristics, and communicating any baseline image metric changes to a management device.

Abstract: Systems and methods are provided for the adaptive detection of audio alarms. A system comprises a microphone configured to receive a series of sounds, a memory configured to store a defined set of alarm templates, a communications network interface, and a processor. The processor is configured to receive and analyze sounds for alarm or background sound characteristics and compare them to a defined set of alarm templates stored in the memory. If not contained in the defined set of alarm templates previously stored in the memory, new alarm templates are learned and stored. An alert is then transmitted to a client device that an audio alarm has been recognized.
