The present disclosure relates to devices and methodologies for assisting caregivers or other interested parties in remotely monitoring elderly individuals living in their homes. Wherein the detectors are positioned, relative to the container whereby the optical path and field of view allows the sensor sufficient focus to view substantially all of the bottom interior surface of the container and substantially all of the solution volume within the container. The buffer can translate controller commands to access information of a specified granularity into subcommands seeking to access information of reduced granularity. Still further, delivery of the electroporation therapy may be synchronized with cardiac qRs complex to avoid impeding normal cardiac rhythm. A semiconductor device, according to embodiments of the disclosure, includes memory cells, each comprising a control gate region and a capping region with substantially aligning sidewalls and a charge structure under the control region. In order to reduce costs, the root part of the blade is formed from spare material entirely located on only one of the two external primary parts of the preform.
