A self-organized and self-managed ad hoc network operates without the intervention of arbitration, collision detectors, hubs, master controllers, switches, or routers. A reset device and method of the present invention also allows the resetcharging process to take place simultaneously with the removal of an encoder-equipped device that is being replaced, as a device of the present invention does not require the use of an encoder-equipped device controller to perform the resetcharging process. The position control provides position indications for the coarse actuator portion, which may comprise a table relating predetermined nominal lateral position indications to the defined servo tracks. The granularity of the lenses and corresponding information can also vary to accommodate different needs and preferences. The multi-layer filter media of the present invention is configured such that the at least one layer of the melt-blown fiber filter media is on the upstream and the at least one electrospun nanofiber filter media is positioned downstream of the at least one melt-blown fiber filter media. Neurodegenerative diseases treatable or preventable according to methods described herein include mild cognitive impairment, Alzheimer’s disease, neurodegeneration in Down Syndrome, Familial British Dementia, and Familial Danish Dementia.
