Abstract: A protective battery case for use with a mobile electronic device can include a back wall, a right side wall, a left side wall, a bottom wall, and a top wall. The protective battery case can include a battery, which can be disposed in the back wall. A device interface can be configured to engage a corresponding interface on the mobile electronic device to deliver electrical power from the battery to the mobile electronic device. A charging interface can be configured to receive electrical power for charging the battery. The protective battery case can include one or more bumpers disposed on the inside of the protective battery case such that the one or more bumpers abut against sides of the mobile electronic device to provide cushioning and/or shock absorption to protect the mobile electronic device.

Abstract: A protective case can house a portable electronic device. The portable electronic device can have a switch (e.g., for switching an operational mode of the portable electronic device). The protective case can have a switch cover that engages the switch of the portable electronic device when the portable electronic device is in the protective case. The switch cover can be moved between positions corresponding to positions of the switch of the portable electronic device. As the switch cover is moved, the switch cover correspondingly moves the switch.

Abstract: An entertainment console installed in a vehicle includes a docking bay for docking portable entertainment devices, such as portable media players (PMPs). A base of the console may be attached to the passenger compartment ceiling, with a display that can be flipped down from the base. A docked PMP can be played through the console. Video may be rendered on the console screen, while audio may be played through the console speaker(s), headphone jacks available on the console, or the speakers of the vehicle's audio system. Power for the PMP's operation is provided by the vehicle's electrical system. The console may also include additional docking bay(s), enabling simultaneous docking of multiple PMPs that may be played at the same time. A presentation from one PMP (e.g., a DVD player) can also be recorded on another PMP (e.g., a hard drive-based player). The screen may rotate around the vertical axis.
