Abstract: The disclosure is directed to illumination-based charging of one or more portable devices. According to an embodiment of the disclosure, an illumination-based charging pad includes a platform, a plurality of illumination sources, a plurality of photosensitive detectors, and a controller. The controller performs a scan by activating the illumination sources and detecting reflected illumination from an illuminated surface of at least one portable device disposed upon the platform. The controller determines a set of one or more illumination sources that are at least partially overlaid by the portable device based upon the detected illumination. The controller selects one or more illumination sources for charging the portable device at least partially based upon the set of one or more illumination sources determined to be overlaid by the portable device.

Abstract: A metal substrate with a slot therein forms a slot antenna, the slot having a major axis and a minor axis. A dielectric layer has a plurality of terminals disposed on or in the dielectric layer and the layer is attached on one surface of the substrate. The terminals of a non-linear device, such as a diode, are connected to corresponding terminals of the dielectric layer. The non-linear device is positioned proximate the slot and is substantially aligned with a minor axis of the slot. A transmission line feeds an RF signal to the non-linear device that in turn frequency multiplies the RF signal to an RF signal that is radiated by the slot antenna. The dielectric layer is positioned in the slot such that the radiated RF signal has a desired output power. A protective layer is applied to the other surface of the substrate to cover the slot.

Abstract: A user device comprises a housing, a processor, a position sensor coupled to the processor, a camera coupled to the processor and a display coupled to the processor. The position sensor is configured to detect at least one particular type of movement of the user device. The display is viewable through at least a portion of a front surface of the housing. The processor is configured to automatically present on the display at least a portion of an image from the camera responsive to the position sensor detecting a given movement of the particular type.

Abstract: The present disclosure is directed to a method for spell checking. The method includes the step of generating a geographic based list of words. The method also includes the step of appending the geographic based list of words to a spell check list. A further step of the method includes detecting a change in position. The method also includes the step of generating a new geographic based list of words when a change in position occurs.

Abstract: An apparatus comprising an interface and a control circuit. The interface may be configured to allow a user to compose an electronic message. The control circuit may be configured to (i) receive motion information during a time when a user composes the electronic message and (ii) embed the motion information within the electronic message in a format readable along with the electronic message.
