Abstract: A secondary UAV flies over the solar-powered UAV at night and illuminates the solar-powered UAV's solar panels to help supplement the solar-powered UAV's battery charge mid-flight. The secondary UAV could be equipped with a directional light source for providing light of a color and intensity selected for optimal absorption by the solar cells of the solar-powered UAV. As the secondary UAV flies over the solar-powered UAV, the secondary UAV could thus direct its light source at the solar-powered UAV for absorption by the solar cells, to help supplement the solar-powered UAV's battery charge. Further, the secondary UAV could potentially recharge multiple solar-powered UAVs during a single nighttime mission.

Abstract: A mobile station receives a neighbor list from a base station in an area of a public wireless network that borders a private wireless network. The neighbor list includes encrypted channel identifiers corresponding to private network channels transmitted by the private wireless network and unencrypted channel identifiers corresponding to public network channels transmitted by the public wireless network. If the mobile station does not subscribe to the private wireless network, the mobile station does not recognize the encrypted channel identifiers and simply ignores them. However, if the mobile station subscribes to the private wireless network, the mobile station decrypts the encrypted channel identifiers and determines whether it is able to initiate a handoff to any of the corresponding private network channels.

Abstract translation: 移动台在与专用无线网络相邻的公共无线网络的区域中从基站接收邻居列表。 邻居列表包括对应于由专用无线网络发送的专用网络信道的加密信道标识符和对应于由公共无线网络发送的公共网络信道的未加密信道标识符。 如果移动台没有订阅专用无线网络，则移动台不识别加密的信道标识符，并且仅仅忽略它们。 然而，如果移动台订阅专用无线网络，则移动台对加密的信道标识符进行解密，并且确定是否能够发起对任何相应专用网络信道的切换。
