The heat conducting pillar is disposed in the accommodating space and physically connected with the upper cover and the lower cover to balance the temperature of the upper cover and the lower cover.

An energy harvesting circuit includes one or more broadband or narrow band antennas to detect WIFI (wireless fidelity) or other RF (radio frequency) signals. The signals are rectified and voltage multiplied, and the resultant DC voltage is provided to a power management circuit. The output of the power management circuit charges a lithium battery or other storage device within the energy harvesting circuit. The energy stored in the battery or storage device is provided through a DC / DC converter circuit to a USB output connector to power or recharge the batteries of an external electronic device connected to the USB output connector of the energy harvesting circuit.

There is disclosed a method and a device for inputting a character into an electronic device, said method comprising detecting an input, activating a temporary input area upon detection of said input, displaying said temporary input area on a display of said electronic device, and terminating the display and deactivating said temporary input area in case that a relevant event is detected. The relevant event may be another user-input.

An electronic device is provided that includes a housing, a plurality of modules, a sensor and a selection mechanism. The housing has multiple housing segments, with each segment housing one of the plurality of modules. The sensor detects an orientation of the electronic device. The selection mechanism automatically selects at least one, but nor all, of the plurality of modules to be active, based on the detected orientation of the electronic device.

The common wiring line includes electrical conductors, a wiring line, and contact holes.

In a portable electronic device (100) having a plurality of near field communication applications stored within a plurality of execution environments, an application discovery manager (311) is configured to automatically select and launch one or more of the near field communication applications. A near field communication circuit (300) receives a near field communication request from an external near field communication device (700). The application discovery manager (311) identifies a near field communication technology, a protocol, and an application identifier and then references a registry table (313) to determine identification parameters corresponding with the identified information. The application discovery manager (311) then selects a near field communication application and launches it. The application discovery manager (311) further configures a routing switch (316) to direct data between the near field communication circuit controller (301) and the appropriate execution environment.

An electrophoresis device includes a pair of substrates, a plurality of pixel electrodes, and a common electrode formed on the pair of substrates, a liquid material formed by dispersing charged particles sealed between the pair of substrates and a driving circuit for applying a voltage to the pixel electrodes and the common electrode to generate an electric field therebetween. When display image is changed, the driving circuit generates a first electric field between all the pixel electrodes and the common electrode to delete the image displayed by that time over the entire display region. Then, when new display image is written, the driving circuit generates a second electric field between the pixel electrodes corresponding to display and the common electrode, and generates a third electric field between the common electrode and the pixel electrodes not corresponding to display.

The apparatus further includes first and second braces provided on the first and second brackets, respectively, and spaced apart from one another along the operating path and a biasing element biasing the first and second brackets toward one another. The first and second braces are configured to grasp an electronic device therebetween. The apparatus is part of a retaining unit also described which includes the mounting apparatus, a pivoting member, a swiveling member, and a base unit.

Providing a light emitting device capable of suppressing the variations of luminance of OLEDs associated with the deterioration of an organic light emitting material, and achieving a consistent luminance. An input image signal is constantly or periodically sampled to sense a light emission period or displayed gradation level of each of light emitting elements of pixels and then, a pixel suffering the greatest deterioration and decreased luminance is predicted from the accumulations of the sensed values. A current supply to the target pixel is corrected for achieving a desired luminance. The other pixels than the target pixel are supplied with an excessive current and hence, the individual gradation levels of the pixels are lowered by correcting the image signal for driving the pixel with the deteriorated light emitting element on as-needed basis, the correction of the image signal made by comparing the accumulation of the sensed values of each of the other pixels with a previously stored data on a time-varying luminance characteristic of the light emitting element.

The present invention discloses a portable electronic device and magnetic fixation board therefor. The magnetic fixation board is disposed on a surface of a wall or a casing of an electrical product. The portable electronic device has at least one first magnetic element and the magnetic fixation board has at least one second magnetic element. The second and the first magnetic elements magnetically attract each other and the portable electronic device is attached to the magnetic fixation board. Based on the attraction interaction between the first magnetic element of the portable electronic device and the second magnetic element of the magnetic fixation board, when the portable electronic device is standing idle, users can directly locate the portable electronic device on the magnetic fixation board in the attraction mode and arrange the portable electronic device conveniently, thereby improving the impressions of using electrical products.
