    • An injection vessel for injecting liquid amendment into contaminated subsurface sediment in ecologically sensitive areas such as shallow water salt marshes, tidal flats, or fresh water wetlands is disclosed. The injection vessel described herein includes a shallow-draft floating platform that has an injection system mounted thereon. The injection system includes an injection grid containing a plurality of injection syringes that receive liquid amendment from a metering pump. The injection grid is lowered such that the output of the injection syringes is within the contaminated sediment. The metering pump provides the liquid amendment to the injection syringes and a fluid path is established that injects the liquid amendment into the contaminated sediment. A propulsion system mounted on the floating platform provides for locomotive and maneuvering power. A control system allows the operation of the system either in a semi-autonomous mode in which an on-board controller is programmed to provide the command signals, or in a remote control mode with an operator providing real time command signals through either a wireless or wired controller. The control system provides propulsion commands to the propulsion system and injection commands to the injection system. The propulsion commands include both locomotive commands and maneuvering commands. The injection commands include the lowering and raising of the injection gird and the operation of the metering pump to dispense the predetermined amount of liquid amendment.
    • 公开了一种注入容器,用于将生物敏感地区如浅水盐沼,潮滩或淡水湿地中的污染地下沉积物注入液体。 本文所述的注射容器包括具有安装在其上的注射系统的浅牵伸浮动平台。 注射系统包括含有多个从计量泵接收液体修复的注射器的注射格栅。 注射网格降低,使得注射器的输出在污染的沉积物内。 计量泵提供对注射器的液体修正,并建立了将液体修补物注入污染沉积物的流体路径。 安装在浮动平台上的推进系统提供机车和机动动力。 控制系统允许系统的操作在半自主模式中,其中车载控制器被编程以提供命令信号,或者在远程控制模式中,操作者通过无线或无线电提供实时命令信号 有线控制器。 控制系统向推进系统提供推进命令,并向喷射系统提供喷射命令。 推进指令包括机车指令和机动指令。 注射指令包括降低和提高注射管和计量泵的操作以分配预定量的液体修正。

    • The novel graphics system (10) includes multiple displays (20 and 22) supported by a single frame buffer (18) thereby reducing hardware requirements and costs. The system (10) further includes an operating system driver interface (12), a software driver interface (14) and graphics circuitry (16). In one embodiment, the graphics circuitry (16) includes a graphics chip (34) for providing an analog output (36) and a digital output (38). The digital output (38) is processed by a data reformatter (40) and a digital-to-analog converter (42) to provide an analog signal (44). The invention thus takes advantage of existing mixed output chips to implement a multiple analog CRT monitor system in a cost effective manner.
    • 新颖的图形系统(10)包括由单个帧缓冲器(18)支持的多个显示器(20和22),从而降低硬件需求和成本。 系统(10)还包括操作系统驱动器接口(12),软件驱动器接口(14)和图形电路(16)。 在一个实施例中,图形电路(16)包括用于提供模拟输出(36)和数字输出(38)的图形芯片(34)。 数字输出(38)由数据重新格式化器(40)和数模转换器(42)处理以提供模拟信号(44)。 因此,本发明利用现有的混合输出芯片以成本有效的方式实现多模拟CRT监视器系统。
