A system and method that uses a non-invasive method, such as a wearable module equipped with sensors placed on a subject connected to a computer-linked module, to monitor life signs like heartbeat waveforms and body temperatures. Life signs indicate the health of a living being or a dynamic system (a mechanical system containing moving parts, like motors). The health of the system is defined by a set of known good spectra (such as its frequency / wavelet transform spectrum), with deviations triggering alerts. A garment embedded with a piezoelectric material and an electronic temperature sensor, when placed in contact with the body, captures acoustic waves from the heart and body temperature. Both sensors are connected to a garment-mounted module with an embedded flexible printed antenna (WEM). A separate WEM with reconfigured daughterboard software forms a bidirectional wireless data connection to a computer. A software program compares the received spectrum to its database spectrum and alerts the user when deviation is determined by a set of rules.

Redundant capacity in a memory system is utilized to facilitate active monitoring of solid state memory devices in the memory system. All or part of the data stored in an active solid state memory device, and used in an active data processing system, may be copied to at least one redundant memory device, e.g., by transitioning a memory address range that was allocated to the active memory device to the redundant memory device. By doing so, memory access requests for the memory address range, which would normally be directed to the active memory device, may instead be directed to the redundant memory device, thus enabling the active memory device to be tested (e.g., via writing and reading test data patterns to the active memory device) without interrupting system access to that memory address range.
