    • A method and system are provided in a wireless communications system comprising a plurality of nodes (users) working cooperatively. The system provides cooperative diversity by allowing nodes to actively share their antennas and other resources to obtain spatial diversity. The nodes receive the same message (information data) from a common source. Each node enhances the reliability of the message with a modern forward error correction (FEC) code, converts the FEC encoded message into an ensemble of symbols, divides the ensemble of symbols into packets, modulates, dithers and transmits the packets to a receiving node. The dithering process is performed by varying the signal amplitude, phase, frequency and/or symbol timing of the modulated packets. A unique dither pattern is assigned to each node. The receiving node captures a composite signal comprising the transmitted packets of all or most of the transmitting nodes in the cooperative communications system. Because the transmitted packets are dithered independently in phase and/or amplitude, spatial diversity is transformed into temporal diversity.
    • 在包括多个合作工作的节点(用户)的无线通信系统中提供了一种方法和系统。 该系统通过允许节点主动共享其天线和其他资源以获得空间分集来提供协作分集。 节点从公共源接收相同的消息(信息数据)。 每个节点通过现代前向纠错(FEC)码增强消息的可靠性,将FEC编码的消息转换为符号集合,将符号集合分成包,调制,抖动,并将数据包发送到接收节点。 通过改变调制分组的信号幅度,相位,频率和/或符号定时来执行抖动处理。 为每个节点分配唯一的抖动模式。 接收节点捕获包括合作通信系统中所有或大多数发射节点的传输分组的复合信号。 由于发送的分组在相位和/或幅度上独立地抖动,空间分集被转换成时间分集。

    • The portable cooler is a portable refrigeration system for selectively and adjustably cooling a removable container, such as a beer keg, for example. The portable cooler includes a housing that defines an open interior region for removably receiving the keg. A door is pivotally mounted to the housing, providing the user with selective access to the open interior region. A refrigeration device is mounted within the housing, adjacent the container, and may be powered by an external power supply or by rechargeable batteries, also received within the housing. Wheels are pivotally mounted to a lower end of the housing, and a handle is mounted to an upper end of the housing, allowing the user to selectively transport the housing and keg.

    • A conference server enables collaborative communications among a variety of client processes of varying configurations all operatively coupled over a computer network to each other and to the server. The server receives audio streams from participating client processes in a conference, selects which audio streams are active, and broadcasts one or more of the active audio streams to the client processes participating in the conference depending on the clients receiving capabilities and the conference parameters. The client processes receiving multiple active audio streams perform mixing locally at the client node. Without having to perform mixing at the server, resources are saved and the number of simultaneous participating client processes to the conference may be increased accordingly. The server is further capable of simultaneously accommodating multipoint clients and non-multipoint H.323 clients, as well as operating in multiway and “push to talk” modes.
    • 会议服务器实现各种各样的配置的客户端进程之间的协作通信,这些配置都可以通过计算机网络彼此和服务器可操作地耦合。 服务器在会议中从参与的客户端进程接收音频流,选择哪些音频流是活动的,并且根据客户端的接收能力和会议参数,向参与会议的客户端进程广播一个或多个活动音频流。 接收多个活动音频流的客户端进程在客户端节点处本地进行混合。 无需在服务器上执行混合,节省资源,并可以相应地增加同时参与的会议客户端进程的数量。 该服务器还能够同时容纳多点客户端和非多点H.323客户端,以及以多路和“一键通”方式运行。

    • An image is updated on a bi-stable display (310) such as an electrophoretic display in a transition from a current image state to a subsequent image state. A voltage waveform (600, 620, 640, 660; 700, 720, 740, 760) is selected based on the current and subsequent image states, and a previous image state. The bi-stable display (310) is driven from the current image state to the subsequent image state using the selected voltage waveform. For a given transition from the current to the next image state, different waveforms are stored for different previous states, e.g., black, dark grey, light grey and white. The different waveforms may have different drive pulse (DR) or reset pulse (RE1, RE2) energies. In a trial and error optimization process, different waveforms with different reset and/or drive pulse energies are tested for different previous image states to see which waveform yields the smallest greyscale error.
    • 在从当前图像状态到后续图像状态的转变中,在双稳态显示器(310)上更新图像,例如电泳显示器。 基于当前和后续图像状态以及先前的图像状态来选择电压波形(600,620,640,660,700,720,740,760)。 使用所选择的电压波形,双稳态显示器(310)从当前图像状态驱动到后续图像状态。 对于从当前图像状态到下一图像状态的给定转换,存储不同的先前状态的不同波形,例如黑色,深灰色,浅灰色和白色。 不同的波形可能具有不同的驱动脉冲(DR)或复位脉冲(RE 1,RE 2)能量。 在试错误优化过程中,针对不同的先前图像状态测试具有不同复位和/或驱动脉冲能量的不同波形,以查看哪个波形产生最小的灰度误差。
