    • A method of manufacture of an anti-microbial polymeric film comprising coextruding a polymeric substrate layer comprising a first layer of a first polymeric material and a second layer of a second polymeric material wherein the crystalline melting temperature (TM2) of said second polymeric material is lower than the crystalline melting temperature (TM1) of the first polymeric material; stretching the coextruded substrate in a first direction; optionally stretching the substrate layer in a second, orthogonal direction; disposing on the surface of the polymeric second layer a composition comprising a particulate antimicrobial compound and a liquid vehicle, and preferably also a surfactant; and heat-setting the stretched film at a temperature above the crystalline melting temperature (TM2) of the second polymeric material but below the crystalline melting temperature (TMI) of the first polymeric material; wherein the composition is applied to the polymeric second layer after the coextrusion step but before the heat-setting step; such that in the final film said second layer comprises said anti-microbial compound in an amount of from about 1 to about 80 % by weight of said polymeric material of the second layer is described. Anti-microbial films are also described.
    • 一种制造抗微生物聚合物膜的方法,包括将包含第一聚合物材料的第一层和第二聚合物材料的第二层的聚合物基底层共挤出,其中所述第二聚合物材料的结晶熔融温度(TM2)较低 比第一聚合物材料的结晶熔融温度(TM1)高; 在第一方向上拉伸所述共挤出的基材; 任选地在第二正交方向上拉伸基底​​层; 在聚合物第二层的表面上设置包含颗粒状抗微生物化合物和液体载体的组合物,优选还包括表面活性剂; 以及在高于第二聚合物材料的结晶熔融温度(TM2)但低于第一聚合物材料的结晶熔化温度(TMI)的温度下热定型拉伸膜; 其中所述组合物在共挤出步骤之后但在热定形步骤之前施加到聚合物第二层; 使得在最终膜中所述第二层包含所述抗微生物化合物的量为所述第二层聚合物材料的约1至约80重量%。 还描述了抗微生物膜。

    • An access device is described herein for determining and selecting, for a cellular call received by a cellular transceiver of the access device, one of a plurality of networks to route the call to. In some embodiments, the determining and selecting may be based at least on a type of each of a plurality of network interfaces of the access device and availability of each corresponding network, the network interfaces including at least two of a cellular retransmitter, an IP networking interface, or a PSTN interface. In various embodiments, if a cellular network is determined and selected, the access device may relay the call. Also, if an IP or PSTN network is determined and selected, the access device may establish on behalf of the call an outgoing call through the IP or PSTN network and translate signals of the cellular call to signals for the IP or PSTN network.
    • 本文描述了一种接入设备,用于确定和选择由接入设备的蜂窝收发器接收的蜂窝呼叫,将多个网络之一路由到呼叫。 在一些实施例中,确定和选择可以至少基于接入设备的多个网络接口中的每一个的类型和每个相应网络的可用性,网络接口包括蜂窝转发器,IP网络中的至少两个 接口或PSTN接口。 在各种实施例中,如果蜂窝网络被确定和选择,则接入设备可以中继该呼叫。 此外,如果确定并选择了IP或PSTN网络,则接入设备可以通过IP或PSTN网络代表呼叫建立呼出呼叫,并将蜂窝呼叫的信号转换为IP或PSTN网络的信号。
