    • An apparatus provides wireless communication between multiple devices within a process control system, such as between field devices, control units, user terminals, controllers, etc., using a wireless bus protocol. In one embodiment, a process control system for use within a process control environment includes a plurality of process control field devices that operate within the process environment, and a control device adapted to receive a sense signal from or to provide a control signal to one or more of the plurality of process control field devices. First and second wireless transceivers are communicatively connected to different ones of the process control field devices and the control device and communicate with one another using a bus protocol, to thereby provide wireless communications within the process control system.
    • 一种装置使用无线总线协议在诸如现场设备,控制单元,用户终端,控制器等之类的过程控制系统内的多个设备之间提供无线通信。 在一个实施例中,在过程控制环境中使用的过程控制系统包括在过程环境内操作的多个过程控制现场设备,以及适于从一个或多个处理环境中接收控制信号或向其提供控制信号的控制信号 更多的多个过程控制现场设备。 第一和第二无线收发器通信地连接到不同的过程控制现场设备和控制设备,并且使用总线协议彼此通信,从而在过程控制系统内提供无线通信。

    • An oral care composition having enhanced flavor release comprising an orally acceptable carrier containing a first flavor and a multilayer film for extended or delayed flavor release, the multilayer film including at least a center layer containing a second flavor, the center layer positioned between two outer surface layers, each surface layer including a release modulating agent, the first and second flavor being the same or different. The film is adapted to adhere to an oral cavity surface and the outer surface layers may comprise a mucoadhesive polymer, e.g. carboxy polymethylene, polycarbophil or polyvinyl pyrrolidone, and a film forming polymer, eg. hydroxypropylmethyl cellulose (HPMC). Suitable release modulating agents include HPMC and polyvinyl acetate. The carrier may be a toothpaste or mouthwash.
