    • An asynchronous serial crosspoint switch is word synchronized to each of a number of transceiver circuits. The crosspoint switch circuit generates both a master bit clock and a master word clock signal. A transceiver circuit recovers the master bit clock signal from an incoming high-speed serial data stream using a clock and data recovery circuit. The recovered bit clock signal is used as a timing signal by which data is serialized and transmitted to the crosspoint switch circuit. The data stream transmitted to the switch circuit is frequency locked to the master bit clock signal, such that the serial data stream need only be phase adjusted with a data recovery circuit. To recover word timing, the switch circuit issues alignment words to the transceivers during link initialization. The transceivers perform word alignment and establish a local word lock. Alignment words are then reissued to the switch circuit using the local word clock. The switch circuit compares the boundary of the received word clock to the master word clock and, if misaligned, the transceiver shifts its transmitted word by one bit and retries. Necessary edge transition density is provided by overhead bits which also designate special command words asserted between a transceiver and a switch circuit. Flow control information is routed from a receiving transceiver back to the transmitting transceiver using the overhead bits in order to assert a ready-to-receive or a not-ready-to-receive flow control signal. The overhead bits additionally provide information regarding connection requests and other information.
    • 异步串行交叉点开关与多个收发器电路中的每一个字字同步。 交叉点开关电路产生主位时钟和主字时钟信号。 收发器电路使用时钟和数据恢复电路从输入的高速串行数据流中恢复主位时钟信号。 恢复的位时钟信号用作定时信号,数据被串行化并发送到交叉点开关电路。 发送到开关电路的数据流被锁定到主位时钟信号,使得串行数据流仅需要用数据恢复电路进行相位调整。 为了恢复字定时,开关电路在链路初始化期间向对收发器发出对准字。 收发器执行字对齐并建立本地字锁。 然后使用本地字时钟将对准字重新发给开关电路。 开关电路将接收的字时钟的边界与主字时钟进行比较,如果未对准,收发器将其发送的字移位一位,然后重试。 必要边缘转换密度由开销比特提供,开销比特还指示在收发机和开关电路之间所确定的特殊命令字。 流量控制信息使用开销位置从接收收发器路由到发送收发器,以便断言即将接收或不准备接收的流量控制信号。 开销比特还提供关于连接请求和其他信息的信息。

    • A water recycling system primarily adapted for use in shower facilities enabling the user to increase both the time duration of a shower and the quantity of water experienced by a user, by maintaining water in a semi-closed system, while both maintaining water and energy conservation. The system preferably operates with fresh and recirculated hot water. The system utilizes spent hot shower water located in the catchment area of a shower or tub and recycles this water to one or more spray heads located at or in the proximity of the regular water dispensing head or so-called "spray head" of that shower. A selected water temperature can be maintained by periodically introducing fresh water or continuously introducing the fresh water at a very low flow rate from a fresh water source, and mixing that water with the recycled water from a water catchment area. Recycled water can also be re-heated and issued again. The apparatus of the system may be provided with an adapter for quick connect and disconnect such that the apparatus can be moved from shower to shower. A manifold forming part of the apparatus includes a check valve arrangement to preclude gray water or spent hot water from entering into the water supply system.
    • 主要适用于淋浴设施的水回收系统,使用户能够通过在半封闭系统中保持水量同时增加淋浴持续时间和使用者体验到的水量,同时保持水和节能 。 该系统优选用新鲜和再循环的热水进行操作。 该系统利用位于淋浴或浴盆的集水区域中的废热水淋浴,并将该水再循环到位于正常水分配头处或附近的一个或多个喷头或所述淋浴器的所谓“喷头” 。 可以通过定期引入淡水或从淡水源以非常低的流速连续引入淡水并将水与来自集水区的再循环水混合来维持选定的水温。 回收水也可以再次加热再次发出。 系统的装置可以设置有用于快速连接和断开的适配器,使得装置可以从淋浴移动到淋浴。 形成该装置的一部分的歧管包括止回阀装置,以排除灰水或废热水进入供水系统。
