Abstract: Helmets for applying a magnetic field to the head of a subject, comprising: a housing comprising a concave surface configured to receive a portion of the head of the subject; a motor coupled to one or more of: a first permanent magnet via a first axle along a first axis of rotation, wherein the first axle drives movement of the first magnet; a second magnet via a second axle along a second axis of rotation wherein the second axle drives movement of the second magnet; and a third magnet via a third axle along the third axis of rotation wherein the third axle drives movement of the third magnet, wherein the axes are parallel; and a fit mechanism comprising a adjuster coupled to the first magnet, wherein movement of the adjustor moves the first magnet independently of the second or the third magnet.

Abstract: A virtual data store system comprises a network interface and a processing device operable to access a source database of data records comprising data, wherein an entity is enabled to utilize the virtual data store system as a database. A verification query is formulated with respect to a data record, that stores an item of data, which is transmitted to online network sources via a proxy service. A query response is parsed and in response to determining that the item of data in the data record is potentially present in the parsed response, a corresponding confidence score is generated. If the confidence score is below a first threshold, a subsequent verification operation is performed. If the subsequent verification operation fails, the second item of data is deleted from memory to conserve memory resources. The data record may be accessed from the virtual data store and used to initiate a networked communication.
