A mobile data storage device is configured in the manner of a data storage card, or a data storage stick. The apparatus includes a modulated pump source for exciting the sample. The top magnetic tunneling junction layer is patterned to form a top magnetic tunneling junction and then a dielectric spacer layer may be formed over the top magnetic tunneling junction. The apparatus is mechanically associated with the seat so that, as the seat reclines, the apparatus moves in relation to the body of the vehicle, and the flange protrudes further into the cargo space as the seat is reclined. The polishing process may be integrated into a multi-step polishing process. Therapeutic compositions containing dantrolene or aminodantrolene are administered to the patient to prevent a rise in cytosolic Ca2 that would otherwise result in Ca2-mediated neuronal damage.
