    • According to one embodiment, a selectively-expandable speakerphone system allows one or more portable computers to automatically, wirelessly interface with a speakerphone console via an audio access point. A scheduling module initiates the conference call at a scheduled time, whereupon the wireless network interface of each portable computer is automatically switched to an SSID uniquely associated with the audio access point, for connecting to the speakerphone console. The audio signals generated by the laptop microphones are mixed with any audio signal generated by an optional microphone on the speakerphone console, and the mixed audio signals are transmitted over the telephone line. Incoming audio signals are passed to the speakerphone console and wirelessly transmitted to the portable computers for substantially simultaneous playback on the respective loudspeakers.
    • 根据一个实施例,选择性可扩展扬声器电话系统允许一个或多个便携式计算机经由音频接入点自动地与扬声器电话控制台接口。 调度模块在预定的时间发起会议呼叫,于是每个便携式计算机的无线网络接口被自动切换到与音频接入点唯一相关联的SSID,用于连接到免提电话控制台。 由笔记本电脑麦克风产生的音频信号与由扬声器控制台上的可选麦克风产生的任何音频信号混合,混合音频信号通过电话线传输。 传入的音频信号被传送到扬声器控制台并且无线地传送到便携式计算机,以便在相应的扬声器上基本同时重放。

    • A data processing system includes a planar board having a central processing unit (CPU), a main memory unit, and input/output (I/O) sockets or slots, each adapted to receive a selected one of a plurality of different and/or similar option cards. each card contains (or is connected to) and controls a respective peripheral device; and each card is pre-wired with an ID value corresponding to its card type. Software programmable option registers on each card store parameters such as designated default (or alternate) address information, priority levels, and other system resource parameters. A setup routine, during initial power-on, retrieves and stores the appropriate parameters in the I/O cards and also in slot positions in main memory, one position being assigned to each slot on the board. Each slot position is adapted to hold the parameters associated with the card inserted in its respective slot and the card ID value. That portion of main memory containing the slot positions is adapted to maintain the parameter and ID information by means of battery power when system power fails or is disconnected, i.e., a nonvolatile memory portion. Subsequent power-on routines are simplified by merely transferring parameters from the table to the card option registers if the status of all the slots has not changed since the last power-down, system reset, or channel reset.
    • 数据处理系统包括具有中央处理单元(CPU),主存储器单元和输入/输出(I / O)插槽或插槽的平面板,每个插槽或插槽适于接收多个不同的和/或 类似的选项卡。 每个卡包含(或连接)并控制相应的外围设备; 并且每张卡都预先连接有与其卡类型对应的ID值。 每个卡上的软件可编程选项寄存器存储诸如指定的默认(或备用)地址信息,优先级和其他系统资源参数的参数。 初始上电期间的设置例程将检索并存储I / O卡中的相应参数,并将其存储在主存储器中的插槽位置,一个位置分配给电路板上的每个插槽。 每个时隙位置适于保持与插入其相应时隙中的卡相关联的参数和卡ID值。 包含插槽位置的主存储器的该部分适于在系统电源故障或断开时通过电池电力来维持参数和ID信息,即非易失性存储器部分。 如果所有插槽的状态自上次掉电,系统复位或通道复位以来没有变化,则仅通过将参数从表传输到卡选项寄存器来简化后续通电程序。
