Abstract: A mobile application running on a host mobile device is used to control the display of notifications, received by the host mobile device, on a mobile device cover. A single button on the mobile device cover is used to display, configure, and navigate through functionality menus of functions provided by the mobile device cover.

Abstract: The mobile phone case is modular in design to provide for a portable smart auxiliary system. The portable smart auxiliary system can be used with mobile phones of various shapes or sizes. To enable the portability and universality of the auxiliary system, the mobile phone case includes at least one interchangeable elastomeric frame that is phone-specific.

Abstract: A mobile device cover displays notifications based on communication received by a host mobile device. The mobile device cover has multiple screens that can be unfolded. The multiple screens can operate as separate displays or at least two of the screens can form a composite display. One of the screens can provide a touch-sensitive keyboard.

Abstract: A battery in a mobile phone cover may be selectively charged according to a user-selectable parameter. When charged, the battery in the mobile phone cover may be used to charge a battery in a mobile phone.

Abstract: A mobile device cover includes a front frame, a middle frame, and a back frame. The mobile phone is placed between guides of the middle frame and then enclosed by the front frame which has an opening for the screen of the mobile phone. The back frame is mounted on the middle frame, thereby enclosing the printed circuit board and the rechargeable battery. Lights on the printed circuit board are visible through the back frame which is transparent or semi-transparent.

Abstract: A battery in a mobile phone cover for use with a mobile phone is used to charge a battery in the mobile phone according to a first battery parameter and a second battery parameter. If an application running on the mobile phone determines that a sensed parameter has fallen below a first battery parameter, then the application causes the battery of the mobile phone cover to charge the battery in the mobile phone until the sensed parameter reaches or exceeds the second battery parameter. The mobile phone cover also provides a notification on its display, for example, of an event (e.g., missed call, calendar alert, received message, etc.) when the event occurs on the mobile phone.

Abstract: Systems and methods of providing a mobile device cover are described. In some embodiments, the mobile device cover may include, for example, an acoustic sensor, a processor, and lighting devices. The processor can be operatively coupled to the acoustic sensor and the lighting devices. The acoustic sensor can be configured to receive sound generated by the mobile phone and to convert the sound into an acoustic signal. The processor can be configured to receive the acoustic signal and to determine whether the acoustic signal is similar to one of a plurality of acoustic signals previously stored on the mobile phone cover. Each of the previously stored acoustic signals can be indicative of, for example, a particular caller, a particular message sender, or a particular alert. Based on the acoustic signal determination, the processor is configured to cause lighting of the one or more lighting devices corresponding to the indicated caller, indicated message sender, or indicated alert.
