  • Publication number: 20150350721
    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.

  • Publication number: 20150145740
    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.

  • Publication number: 20150022704
    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.

  • Publication number: 20140369696
    Abstract: Data transmission method and apparatus utilizing color coding is disclosed. A one-to-one correspondence between a set of eight unique 3-bit data units and a set of eight unique color representations is established for color coding a sequence of 3-bit data units. Transmission of the sequence of 3-bit data units is then facilitated using a sequence of color representations, wherein each one of the sequence of 3-bit data units has a one-to-one correspondence with one of the sequence of color representations.

  • Publication number: 20140369395
    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.

  • Patent number: 8886166
    Abstract: The present invention concerns an apparatus comprising a first module and a second module. The first module may be configured to send a text message over a wireless network in response to one or more user keystrokes. The first module may generate a body of the text message and a security key to be transmitted along with the body of the text message. The second module may be configured to receive the body of the text message and the security key over the wireless network. The second module compares the security key to a set of known security keys to determine a match. A match indicates whether the text message was generated from a known sender. The first and second modules may be implemented as part of a portable device.

  • Patent number: 8859395
    Abstract: Techniques for processing power transistor devices are provided. In one aspect, the curvature of a power transistor device comprising a device film formed on a substrate is controlled by thinning the substrate, the device having an overall residual stress attributable at least in part to the thinning step, and applying a stress compensation layer to a surface of the device film, the stress compensation layer having a tensile stress sufficient to counterbalance at least a portion of the overall residual stress of the device. The resultant power transistor device may be part of an integrated circuit.
