Systems and methods are provided for attaching and positioning a personal computing device case to a folio. The folio includes magnetic connections, and the personal computing device case includes magnetic connections for attaching the case to the folio in any one of a plurality of positions. The magnetic connections of the folio include an upper magnet array and a lower magnet array for attachment of the magnetic case. The folio includes a hinge mechanism at a top edge of each of two sides of the folio. The case is attached to the folio using guided magnetic seating, and the case is repositionable by slidingly or rotationally changing the position of the case relative to the folio.

Magnetic case and folio for portable personal computing device

An improved rotary engine that harmoniously produces multiple, sequential cycles. A main housing is comprised of a concentric stator sandwiched between a front and an aft wall enclosing a cylindrical inner space. A network of combustors are stationed about the stator periphery. Mounted on a central axis within the inner space is a concentrically revolving rotor body. The combustors sequentially introduce a working fluid into a plurality of expansion chambers symmetrically stationed within the rotor body. As the rotor is propelled by the working fluid, a variable vane transversely mounted within each expansion chamber simultaneously performs work on a fluid in a compression region. The compressed fluid of each cycle is discharged and diverted to compliment the combustor of a sequential cycle. A high degree of power and efficiency is achieved using simple mechanics to produce multiple cycles during each revolution.
