Abstract: A computer system, computer readable storage medium, and computer-implemented method for detecting if one or more processing devices have separately sourced power feeds. The method includes determining transmission of a first signal in a first electric path. The method also includes monitoring for a second signal in a second electric path that is different from the first electric path. The method further includes determining, subject to the monitoring, electrical isolation between the first electric path and the second electric path. The claimed computer-implemented method dynamically, and automatically, determines that power sources are separate, isolated, and redundant.

Abstract: A resonant sensor is embedded within or applied to a component of a medical diagnostic apparatus. The resonant sensor is formed from a composite material. The resonant sensor undergoes a change of permittivity and/or change in permeability due to metabolic activity of a microorganism that is involved in the medical diagnostic and proximal to the resonant sensor. The medical diagnostic apparatus may be a blood culture bottle that is configured to contain a blood culture medium. The resonant sensor may be embedded in or applied to the exterior or interior wall of the blood culture bottle. The resonant sensor may undergo a change in permittivity and/or a change in permeability due to production of carbon dioxide by the microorganism. The composite material may comprise a carbonaceous material such as graphene.
