An attachment system is disclosed which employs a main set of attachment elements attached to a case for a mobile computing/communication device, such as a mobile phone, computing tablet or other computing device which can be carried with the user. The attachment system may also be part of the mobile computing/communication device. These attachment elements are designed to attach to attachment elements connected to, or built into another mobile computing/communication device. This allows a user to keep track of a first phone while using a second phone. In alternative embodiments, the phone may be connected back to back to allow simultaneous use of both phones, front to back to protect the screen of one while using the other, or front to front to protect both screens when neither is being used. Also, it may be embodied as a docking structure which is fixed to a wall or other structure. The mobile computing/communication device removably attaches to the docking structure to hold the phone for use and/or storage.

A plurality of modules are connected to the front side and back side of an electronic device via corresponding attachment/detachment units. The electronic device includes an orientation detection unit that detects the orientation of the electronic device. Based on a selection of a module to be removed and a touch operation on a touch panel of the electronic device, the selected module is determined to be either on the front side or the back side of the electronic device. When the electronic device is in an orientation suitable for removal of the selected module, the module is disconnected from the electronic device by a corresponding attachment/detachment unit.

An expansion module (10) for a personal mobile device (100) with a transceiver (1) which is designed to transmit and receive data (D) by means of a first, in particular real-time-enabled, radio standard (F1), a data interface (2) which is designed to forward data (D) which have been received by the transceiver (1) by means of the first radio standard (F1) to the personal mobile device (100) and/or to forward data (D) which have been received by the personal mobile device (100) by means of a second radio standard (F2), which differs from the first radio standard (F1), to the transceiver (1).

A method of operating a device to obtain biometric information from a subject includes the step of orienting a device relative to a sub jest such that a first portion of the device faces the subject, wherein a second FIG. 1A portion of the mobile device comprises a camera, the first and second portions being different sides of the device. The method may further includes the steps of operating an optical assembly that is movably coupled to the device, the optical assembly being configured to modify an optical pathway of at least the camera in a direction of the subject and acquiring imaging data of the subject using the camera. The method may further includes the steps of analyzing the acquired imaging data to generate biometric information corresponding to the subject and generating a report using the biometric information.

A wireless earphone comprises a transceiver circuit for receiving streaming audio from a data source over a local ad hoc wireless network. When the data source and the earphone are out of range, they transition automatically to an infrastructure wireless network. If there is no common infrastructure wireless network for both the data source and the speakerphone set, the earphone connects to a host server via an available wireless network.

A speaker system is removably attached to a cellular telephone or telephone case to augment or supplant audio output of the phone. In one example, the system includes a protective telephone case with built in speakers. The attachment mechanism may alternatively or additionally be used as a universal attachment for cellular telephone accessories. The system may include a fastening mechanism configured to attach any accessory to a phone surface.

Examples herein include modules and connections for modules to couple to a computing device. An example module includes a housing comprising an end to couple to a computing device, multiple capacitive pads that each include data contacts to enable data transfer, a power contact pad to provide or receive power, and a ground contact pad to couple to ground. The ground contact pad is larger in size than the power contact pad, and the ground contact pad is positioned closer than the power contact pad to the end of the housing configured to couple to the computing device.

A rollable display device is provided. An exemplary embodiment of the present invention provides a rollable display device including: a display body including a display unit configured to display various types of information as an image on one surface thereof and provided to be rollable; and a flexible battery provided on the display body and configured to supply power to the display body.

A phone case with a secondary housing retainer attached to the underside of the phone case. The secondary housing retainer can receive a rectilinear secondary housing that can act as a cigarette holder, wallet, cosmetic holder or battery charging unit. The secondary housing includes a hinged lid that can be opened even when the secondary housing is within the housing retainer. A third housing built into the underside of the cell phone retaining case has a hinged lid allowing the outermost panel to open or close. The third housing has a triangular cross section. In a second embodiment the secondary housing is a removable cosmetic tray that is covered by a hinged cover plate.

An apparatus for enveloping a portable communication or storage device includes a plurality of walls configured to at least partially enclose the portable communication or storage device. The apparatus also includes a processor, and a first shutter that is associated with one or more of the walls. The first shutter is operatively coupled to the processor, and is disposed so as to overlie a first camera lens of the portable communication or storage device. The first shutter has a first condition in which the taking of digital impressions with the first camera lens is unobstructed, and a second condition in which the taking of digital impressions with the first camera lens is hindered. The processor is configured to verify that a plurality of conditions is met before allowing the first shutter to toggle between the first and second conditions of that first shutter.
