A UV-C emitting phone case is provided that includes a main body defining a receiving cavity and a perimeter configured to receive and hold a mobile phone, surround a perimeter and a back portion of the phone. The phone case includes at least one UV-C light emitting diode (LED) positioned in the main body of the phone case and exposed on a back side of the phone case. It further includes a window for exposing the UV-C LED and optionally having a color metric to indicate if the light is being emitted, a power source built into the phone case and connected to the UV-C LED; an on/off switch coupled to the power source configured to activate and deactivate the UV-C LED; and an optional distance sensor to indicate a distance from a target surface to the UV-C LED.

In accordance with some embodiments, an apparatus for privacy protection includes a housing arranged to hold a second device, a local communication device at least partially supported by the housing, and a controller, where the apparatus is associated with a radio frequency (RF) power detector. The RF power detector monitors energy emitted from one or more antennas of the second device in response to determining that the second device indicates that the second device has transitioned from a first mode of operation to a second mode of operation. The apparatus further establishes a communication channel between the apparatus and the second device, and obtains, through the communication channel, a communication status of the second device. The apparatus can then report compromise of the second device upon determining that a discrepancy between the communication status and the energy emission.

The present disclosure provides an auxiliary device that implements both free-stop hinge and click hinge and includes a seating member forming a seating area for a mobile terminal to implement a neat appearance and a hinge module rotatably connecting the cover member to the seating member, wherein the hinge module includes a holder, a rotation member including a first rotation member fixed to the seating member to form a first rotation axis between the holder and the seating member, and a second rotation member fixed to the cover member to form a second rotation axis between the holder and the cover member, the second rotation axis being parallel with the first rotation axis, and an elastic member configured to elastically press the rotation member to prevent a rotation due to a predetermined magnitude of force or less.

A device for holding and charging an electronic cigarette element includes a housing configured for coupling to a rear of a mobile computing device, the housing including a rechargeable battery, a first power port in the housing, the first power port conductively coupled to the rechargeable battery and configured for accepting external power for recharging the rechargeable battery, a first receptacle in the housing, wherein the first receptacle is configured to accept an electronic cigarette element, a charging terminal conductively coupled to the rechargeable battery, wherein when the electronic cigarette element contacts the charging terminal, the rechargeable battery recharges a battery of the electronic cigarette element, and, a second receptacle in the housing, wherein the second receptacle is configured to accept a cartridge for the electronic cigarette element.

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.

The present disclosure relates to a sled attachable to a mobile device. The sled comprises a chargeable protective case, an externally powered device such as a mobile payment device, and one or more batteries.

An apparatus for carrying out inputs in an input capturing unit that can be coupled to the apparatus. An operating device has a receiving part and an operating element that is rotatably mounted on the receiving part. The operating element can be rotated by a finger to effect an input. A torque for the rotation of the control element can be adjusted by way of a controllable braking device. In addition, the control element has at least two actuating zones. The resistance to movement for the movability of the operating element can be adjusted depending on from which actuation zone the operating element is actuated and/or which actuation zone was previously activated.

A wireless communication system comprising a smartphone comprising antenna system, and an add-on device that is configured to be attached to the smartphone, wherein, the add-on device comprises, a wireless communication module configured to transmit and receive RF communication signals, and an antenna coupling system that couples between the wireless communication module and the smartphone's antenna system in order to at least transmit or receive the RF communication signals by the smartphone's antenna system, the antenna coupling system couples the RF communication signals by at least one of or the combination of (a) conduction with the enclosure of the smartphone, and (b) induction between the add-on device and the smartphone.

Various embodiments of the present invention relate to an electronic device having covers which may be coupled and an operating method thereof, the electronic device may include a housing; a first cover coupled with at least part of the housing, and comprising at least one first identification terminal; a second cover coupled with at least part of the first cover, and comprising at least one second identification terminal which is electrically connectable with the first identification terminal; and a processor. The processor may be configured to obtain at least one of first information related to the first cover or second information related to the second cover, identify at least one of a type of the first cover or a type of the second cover based on at least one of the first information or the second information, and perform a designated operation based on at least one of the type of the first cover or the type of the second cover. Other various embodiments are possible.

A sleeve or case for a mobile device, such as a smartphone or tablet or other types of hand-held device or mobile smart device, has a sleeve part for at least partially enclosing the mobile device and an input device arranged in the sleeve part for controlling the mobile device which can be received in the sleeve part.
