    • Protocols and algorithms for contention-based adaptive modulation networks, typically used in unlicensed bands. A wireless system in which high modulation rate packets are prioritized over low rate packets. The wireless system is configured to process communication signals from plural user portable devices having wireless access points capable of dynamically adjusting access point transmit power on a user-by-user basis to a minimum level required to achieve a target signal-to-noise ratio from each user portable device irrespective of the interference observed on the link is also disclosed. The wireless system is also capable of dynamically adjusting access point transmitter power and receiver sensitivity on a user-by-user basis to a minimum level required to achieve the highest possible modulation rate.
    • 用于基于争用的自适应调制网络的协议和算法,通常用于非许可频带。 一种其中高调制速率分组优先于低速率分组的无线系统。 无线系统被配置为处理来自具有无线接入点的多个用户便携式设备的通信信号,所述无线接入点能够在逐个用户的基础上将接入点发射功率动态地调整到实现目标信噪比所需的最小电平 还公开了每个用户便携式设备,而不考虑在链路上观察到的干扰。 无线系统还能够在逐个用户的基础上将接入点发射机功率和接收机灵敏度动态调整到达到最高可能调制速率所需的最低水平。

    • An apparatus for mounting an air conditioner unit on a sill of a window opening in a wall wherein the apparatus comprises a substantially horizontal platform adapted for resting on a sill and receiving an air conditioner unit. The platform comprises a first and second jaw extending below the platform from opposite ends thereof and adapted for opposed relative movement at ends of the jaws remote from the platform for contact with said wall. The apparatus further comprises a biasing means for releasably securing the jaws in contact with the wall whereby the apparatus, sill and wall form a non-yielding structure.
    • 一种用于将空调单元安装在墙壁上的窗口的门槛上的装置,其中该装置包括适于搁置在基座上并接收空调单元的基本上水平的平台。 所述平台包括从所述平台的相对端部延伸到所述平台下方的第一和第二钳口,并且适于在远离所述平台的所述爪的端部处与所述壁接触的相对的相对运动。 该装置还包括用于可释放地固定夹爪与壁接触的偏置装置,由此装置,门槛和壁形成非屈服结构。
