    • A method and corresponding apparatus for maintaining constant bandwidth over a frequency spectrum in a microwave, dielectric resonator waveguide filter. Bandwidth is determined by the product of the resonant center frequency and the interresonator coupling coefficient. To maintain constant bandwidth while changing center frequency, the interresonator coupling coefficient must be chosen such that it varies inversely with changes in center frequency. The interresonator coupling coefficient is a function of the physical dimensions of the waveguide and the dielectric resonators, the dielectric constant and the spatial location of the resonators within the waveguide. Once the physical and spatial parameters have been established, the center frequency of the filter may be adjusted by altering the thickness of the resonators without changing the filter bandwidth.
    • 一种用于在微波介质谐振器波导滤波器中的频谱上保持恒定带宽的方法和相应装置。 带宽由谐振中心频率和谐振器耦合系数的乘积决定。 为了在改变中心频率的同时保持恒定的带宽,必须选择谐振器耦合系数,使其与中心频率的变化成反比变化。 谐振器耦合系数是波导和介质谐振器的物理尺寸,谐振器在波导内的介电常数和空间位置的函数。 一旦建立了物理和空间参数,可以通过改变谐振器的厚度而不改变滤波器带宽来调节滤波器的中心频率。

    • A method and a wireless device (120, 122) utilize auxiliary information associated with an emergency alert system alert message to direct a user of the wireless device (120, 122) to safety. A wireless communication system (102) wirelessly transmits an emergency alert system (EAS) alert message to a wireless device (120, 122). The wireless communication system (102) also wirelessly transmits an augmented EAS alert message to the wireless device (120, 122). The augmented EAS alert message includes auxiliary information that provides information to the wireless device (120, 122) to direct a user of the wireless device (120, 122) to move at least one of toward a safe zone (150) and away from a danger zone (158). The auxiliary information in the augmented EAS alert message is optionally adjusted based on any combination of: the location of the wireless device, the safe zone, and the danger zone, and the logistics of a vicinity affected by the danger zone.
