The present invention is generally directed to energy storage systems comprising manufactured architectural materials having electrical battery systems embedded therein. The manufactured materials are generally provided as architectural panels, such as panels useful for interior or exterior cladding for buildings, flooring, countertops, or stairs. The panels comprise at least one battery device or battery assembly that is over-formed by and/or bonded with the architectural material. In preferred embodiments, the panels are formed by flowing a viscous architectural material precursor around the battery device or assembly and curing the precursor so as to solidify the architectural material. The panels may be electrically connected in any number of various arrangements, which can be chosen based on the specific application for the energy storage system.

Provided is a system and medical device that includes self diagnosing control switches. The control switch may be slidable within a slot in order to control activation of some function of the medical device. Due to natural wear and tear of movement of a control switch, the distances along the sliding slot that correspond to how much energy is used for the function may need to be adjusted over time in order to reflect the changing physical attributes of the actuator mechanism. The self diagnosing control switches of the present disclosures may be configured to automatically adjust for these thresholds using, for example, Hall effect sensors and magnets. In addition, in some cases, the self diagnosing control switches may be capable of indicating external influences on the controls, as well as predict a time until replacement is needed.
