Abstract: Systems and methods for Energy Storage-based Packetized Delivery of Electricity (ES-PDE) are disclosed that are radically different from the operation of today's grid. Using ES-PDE, the loads are powered by the energy storage systems (ESS) the majority of the time and only receive packets of electricity periodically to charge the ESSs. Therefore, the grid operators can schedule the delivery of electricity packets to utilize the existing grid infrastructure. Since the customers are powered by the co-located ESSs they are not impacted by the grid operation in short term. Therefore, when grid outages occur, the customers still have power for some time, giving the grid more time to be fully restored.

Abstract: A caloric testing apparatus for introducing heated or cooled air, under direct visual control, into the outer ear canal of a human subject for purposes of testing inner ear balance mechanisms. The device includes a speculum for observing the ear canal during the flow of air, thereby assuring proper direction of the impinging air jet. The apparatus includes temperature-controlled liquid baths for providing hot or cold air, and has arrangements for providing suitably timed irrigation periods, adjustable so as to control the magnitudes of the caloric stimulations. Measurements can be made by the electrical recording of eye movements for accurate measurement of nystagmic response intensity.
