  • Wireless Network Antenna Apparatus and Method
    Publication number: 20130227619
    Abstract: An antenna for broadcast television programming includes a tuner and demodulator located with the antenna to generate a demodulated television program stream. A network interface is connected to the tuner and demodulator to provide the television program stream to a network, preferably a wireless network. A television set located remotely from the antenna receives the television program stream via the network and displays the program. A portable control device may be connected to the network. Reception of the broadcast programming is improved by controlling the directionality of the antenna in response to the demodulated signal. A service provider may poll the wireless network antenna to determine which broadcast programs are received and may provide extended programming television programs to the user by an internet connection to the user's network.

  • Metal Treatment
    Publication number: 20130075267
    Abstract: Metal implants (10) are treated by anodising the surface (11, 12) in contact with an electrolyte, and then briefly subjecting the anodised surface to a reversed voltage. During a first anodising stage the surfaces are passivated, while during a subsequent anodising stage pits are formed in the passivating surface layer. Rough portions (15) of the surface, in particular portions produced by plasma spraying of metal powder, are sealed with a watertight cover (20) during at least part of the anodising process. After rinsing, biocidal metal ions are subsequently absorbed into the surface of the implant. This provides the implant with biocidal properties. The use of the cover (20) enables a more uniform geometric distribution of biocidal metal ions to be achieved.

  • Multi-Headed Thin Client
    Publication number: 20130042012
    Abstract: Images from web pages may be classified based on the text associated with the images. A system for identifying and classifying images may identify one or more web pages containing the image, determine topics from the text of the web pages, and develop a set of training phrases for a classifier. The classifier may be trained, then used to analyze the text in the web pages. The training set may include both positive examples and negative examples of text taken from the website. A positive example may include captions or other elements directly associated with the image, while negative examples may include text taken from the web page, but from a large distance from the web page. In some cases, the system may iterate on the classification process to refine the results.
