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: An electronic device comprising an image sensor, an orientation sensor, and a user interface, may be operable to capture photographs via the image sensor. Input to the user interface required for triggering a photo capture may depend on an orientation of the electronic device indicated by the orientation sensor. Input required to trigger a photo capture while the orientation sensor indicates a first orientation of the electronic device may be different than input required to trigger a photo capture while the orientation sensor indicates a second orientation of the electronic device.

Abstract: In one embodiment, a radio receiver has a first downconverter, a second downconverter, first and second analog-to-digital converters, and an error detector. The first downconverter downconverts a received RF signal into a first baseband-frequency signal using a first downconversion technique, and the second downconverter downconverts the received signal into a second baseband-frequency signal using a second downconversion technique, different from the first downconversion technique. The first and second analog-to-digital converters convert the first and second baseband-frequency signals into first and second baseband digital signals, respectively. The error detection logic detects errors in at least one of the first and second baseband digital signals based on a comparison of the first baseband digital signal to the second baseband digital signal.

Abstract: A system and method for improved channel scanning in an HDTV device queries a database with location data input by the user, receiving an ordered list of potential channels associated with the selected location. The system may scan only those potential channels on the ordered list, storing successfully decoded channels in memory. The system may further divide the ordered list into groups based on the relative signal strength of potential channels. If a potential channel of the lowest relative signal strength group cannot be successfully decoded, the system may indicate that scanning is complete.
