An electronic reading device includes a mid-frame structure such that the mid-frame structure can include a reverse draft. A reverse draft corresponds to a back of the electronic reading device being a predetermined amount wider than a front of the electronic reading device. Additionally, a co-molded mid-frame stiffener provides a predetermined rigidity of the electronic reading device. The electronic reading device also includes a display integrated with the front of the mid-frame structure, wherein a space between the display and the mid-frame structure includes one or more electronic reading device components. Similarly, a back cover is integrated with the back of the mid-frame structure, wherein a space between the back cover and the mid-frame structure includes additional electronic reading device components.

A mobile device has at least one grip handle disposed on the back surface of the mobile device. The grip handle comprises at least one grip surface that enables a user to grasp the mobile device and use it with one hand of the user. Various embodiments of the invention are disclosed.

Exemplary embodiments of an attachment for a handheld device are provided. In some exemplary embodiments, an apparatus is provided for securing a handheld device, having an attachment body having a top portion, a flat bottom portion and a side portion between the top portion and flat bottom portion, and a securement portion having a bottom that is flush with the bottom portion of the attachment body. The securement portion has an aperture in the bottom of the securement portion leading into an opening that is enclosed by a top of the securement portion, and the flat bottom portion of the attachment body is configured to be attached to a handheld device such that the aperture is sealed when the attachment body is connected to the handheld device. The attachment body can be disc-shaped.

A handle for holding a mobile device with at least one finger has a first element attachable to a back of the mobile device, and a second element pivotally connected to the first element for pivoting around a pivot axis extending in an axial direction, the second element includes at least two branches spaced from one another in a direction which is parallel to the axial direction and each having a finger receiving opening, in a folded position of the first and second elements the second element extends along the back of the mobile device, while in a pivoted away position of the second element relative to the first element the first and second elements are located at an angle relative to one another, and each of the branches of the second elements has a first portion located closer to the pivot axis and a second portion located farther from the pivot axis and formed so that when a finger of a user is introduced into the finger receiving opening of any of the branches it is surrounded by the first portion of said branch which is located closer to the pivot axis and the second portion of the branch which is located farther from the pivot axis correspondingly from two sides.

A signal processing device, which processes a baseband signal for wireless communication, includes a plurality of temperature sensors arranged to sense internal temperatures of the signal processing device, respectively, a threshold storage storing a plurality of thresholds, and a controller that estimates a surface temperature based on the sensed internal temperatures and performs a thermal mitigation operation based on the surface temperature and a plurality of temperature ranges defined by the plurality of thresholds.

An electronic device includes an adjustable RGBW front light. The electronic device additional includes circuitry configured to determine if a transition between phases has occurred, the phases being based on a time of day, automatically display a predetermined screen color temperature via the adjustable RGBW front light in response to the transition between phases, and automatically adjust a predetermined mixture of light to be displayed via the adjustable RGBW front light such that the predetermined screen color temperature does not change in response to a change in a brightness level of the electronic device.

Systems and methods for use with a mobile electronic device comprising a sensor operatively associated with the mobile electronic device for detecting contact with the display and a feature that helps prevent unauthorized access to the mobile electronic device responsive to the determination that the detected contact is accidental, and in some embodiments, the systems and methods of the invention include a case for mating with the body, a sensor mounted to the case, and a software application stored in the memory of the mobile electronic device, the application being in communication with the sensor for detecting contact with the cover to receive data relating to the contact and determine whether the contact is accidental contact, wherein the mobile electronic device is made inaccessible responsive to the determination that the detected contact is accidental.

A textured enclosure component including two different types of surface features is disclosed. The two different types of surface features are differently sized. The combination of differently sized surface features provides both anti-glare and anti-reflective properties to the enclosure component.

A portable radio system including dual programmable push-to-talk (PTT) switches is disclosed. One embodiment includes the PTT switches positioned so as to permit ambidextrous operation of the portable radio. Another embodiment allows a user to program the PTT switches to execute different functional tasks.
