  • Publication number: 20240243471
    Abstract: A quadri-polarization diversity antenna system is disclosed. According to embodiments of the present disclosure, an antenna system includes an antenna array including a first column of dual-polarized antenna units and a second column of dual-polarized antenna units. Each of the dual-polarized antenna units includes a first antenna element and a second antenna element perpendicularly crossing each other. In each column, the first antenna elements are conductively connected to form a first subarray and the second antenna elements are conductively connected to form a second subarray. The antenna system further includes an RF matrix that selectively adjusts phases of RF input signals to generate RF output signals provided to the subarrays. When the RF output signals are radiated by the dual-polarized antenna units, a first beam with +/?45° polarizations and a second beam with 0°/90° polarizations are formed, and the first beam and the second beam are formed toward spatially different directions from each other.

  • Patent number: 9698021
    Abstract: In a method of forming a layer, a substrate is loaded into a chamber and placed at a home position that is a first relative angular position. A process cycle is performed a number of times while the substrate is at the home position. The cycle includes directing source gas onto the substrate at a first location adjacent the periphery of the substrate, purging the chamber, directing reaction gas onto the substrate from the first location, and purging the chamber. The cycle is performed another number of times while the substrate is at another relative angular position, i.e., at a position rotated about its general center relative from the home position.

  • Patent number: 8242159
    Abstract: Disclosed herein are novel 1,3-dihydro-5-isobenzofurancarbonitrile derivatives represented by Formula 1, or pharmaceutically acceptable salts thereof. Also disclosed is a pharmaceutical composition for treating or preventing premature ejaculation including the compound. The 1,3-dihydro-5-isobenzofurancarbonitrile derivatives have a short half-life and inhibit the ejaculation process by selectively inhibiting serotonin reuptake via a serotonin reuptake transporter present in a presynaptic neuron. Thus, the compounds are useful in the treatment and prevention of premature ejaculation.
