Mobile device cases are provided which, in a first embodiment, selectively limit a user's ability to control the user's own mobile electronic device. The case includes front and rear portions joined together and defining therein an opening for receiving a mobile electronic device, such as a mobile phone. A locking mechanism is provided for selectively securing the opening in a first locked position to prevent operational access to the mobile electronic device by the user until a predetermined condition is met. The case includes an indicia of time visible to the user during the period of time of prevented operational access. In a further embodiment, a case is provided with first and second polymeric shells each having an interior and an exterior surface thereon and connected together by at least one hinge portion. The first and second shell portions form a cavity of sufficient size to cover a mobile electronic device sufficiently to prevent access by its user. Tamper resistant and ultrasonic sensor defeating mobile device case embodiments are also contemplated by this invention.

Aluminum-air battery units and stacks are provided with frames configured to mechanically support the anode of each unit, within a housing configured to support the frame and the air cathode(s) mechanically, sealably hold the electrolyte within the housing and in fluid communication with openings in the housingforming one or two sided electrochemical cell in each unit. The frame comprises a protective strap configured to protect edges of the rectangular anode against corrosion by the electrolyte during operation, and also an external trapezoid shape that is configured to press the protective strap against the edges of the rectangular anode upon insertion of the frame with the anode into the housing. Various embodiments comprise, spacers between the anode and cathodes and grids supporting airways to the cathodes. In disclosed configurations, anode may be replaced after electrolyte evacuation while maintaining the stack sealed and quickly ready for renewed operation.

Various embodiments of the present invention relate to an electronic device for recognizing a SIM card. The electronic device may comprise: a display; a SIM card including at least one subscriber identification module; a processor electrically connected to the display and the SIM card; and a memory electrically connected to the processor, wherein in the memory stores instructions which, when executed, cause the processor to: identify whether a SIM lock is activated or not, on the basis of the at least one subscriber identification module included in the SIM card; and when it is identified that at least one subscriber identification module, the SIM lock of which has been deactivated, display a screen corresponding to the subscriber identification module, the SIM lock of which has been deactivated. Another embodiment is possible.

Described is a smartphone lock box system that is used to track and record when and how long a mobile computing device is locked or secured in a container, such as a box, a sleeve or the like, without access by the owner of the mobile computing device. The smartphone lock box system is used to help the owner of a mobile computing device disconnect from the mobile computing device to devote time and attention to other tasks. The smartphone lock box system includes a container that holds at least one mobile computing devices such as a smartphone or tablet. The mobile computing device operating a lock box application senses it is within the container and records and reports the amount of time the mobile computing device is in the container and tracks the frequency that the user checks or removes the phone from the container.

A detox element or sensor cover is placed at a first location over a sensor such as a camera used to activate a digital device. The sensor cover can leave the digital device in sleep mode until the detox element/sensor cover is removed. The detox element, when not in use for detoxing, is moved to a ready position. The ready position can be, for example, one of the corners of the digital device, where it is mostly out of the way of a touch screen display. The sensor cover is sufficiently small that in one embodiment it is mostly on a bezel of a phone, around a display, with only a small portion impinging on the display.

Digital device detox bands are disclosed. For one example, a digital device band comprises an elastic part to stretch around a digital device having one or more sensors, and a cover connected to the elastic part to be placed over at least one of the one or more sensors. The cover is positioned to cover the one or more sensors such that the one or more sensors are prevented from activating the digital device when in a sleep mode The one or more sensors include a camera, a touch sensor, or an activation button to activate the digital device. The elastic part stretches horizontally or vertically to snugly fit around the digital device which can be a mobile phone, mobile computing device or pad having varying dimensions.
