  • Publication number: 20130078304
    Abstract: The invention relates to a controlled-release formulation for preventing and/or treating sleep disorders comprising Zaleplon or a pharmaceutically acceptable salt thereof in immediate release form and Zolpidem or a pharmaceutically acceptable salt thereof in sustained release form, wherein Zaleplon or a pharmaceutically acceptable salt thereof and Zolpidem or a pharmaceutically acceptable salt thereof are released in two phases where the first phase is a immediate release phase of Zaleplon or a pharmaceutically acceptable salt thereof and the second phase is a sustained release phase of Zolpidem or a pharmaceutically acceptable salt thereof.

  • Patent number: 6861987
    Abstract: A bilayer microstrip reflector antenna is disclosed to include a first dielectric layer, the first dielectric layer having antenna units and phase-delay circuit units overlapped on antenna units, and a second dielectric layer abutting against the first dielectric layer. A better gain-bandwidth is obtained by adjusting the overlapping distance of the antenna units and phase-delay circuit units, side length of antenna units and the dielectric constant and thickness of the two dielectric layers. Surface wave phenomenon is reduced by means of selecting a relatively lower dielectric constant. A satisfactory grounding effect is obtained to reduce radiation from phase-delay circuit units by lowering the second dielectric layer toward the ground.
