Abstract: A device may include a first rigid panel having a contact surface and a cosmetic surface. A device may include a frictious material positioned on the contact surface of the first rigid panel. A device may include a second rigid panel having a contact surface and a cosmetic surface, the second rigid panel movably connected to the first rigid panel by a hinged connector. A device may include a selective connector, including: a first connection interface coupled to the first rigid panel, and a second connection interface coupled to the second rigid panel.

Abstract: A personal information system is provided. The system may include a portable information device having a housing including a top surface defined at least partially by a display, a bottom surface configured with a central region in which an optical sensor, electrical connector, and data connector are positioned, the housing enclosing an internal volume in which a processor is provided, the top surface and bottom surface being coupled by a perimeter side edge extending therebetween, and a mounting structure formed at least partially around the perimeter side edge of the housing. The system may further include a frame, which may be connected to a band, the frame surrounding a void and configured to receive the mounting structure, the frame and mounting structure being releasably securable via a tongue and groove connection. The system may further comprise a dock to which the information device may be connected.
