    • A medical device is disclosed, comprising a substrate, having on its surface, on at least a part thereof, a hydrophilic surface layer providing low-friction surface character of the medical device when wetted by a wetting fluid. The substrate is made of a polymer blend comprising a polyolefin and a composition having molecules with active hydrogen(s), such as polyamide or polyurethane. The hydrophilic surface layer is preferably adhered to the substrate by a polyurea network, whereby said polyurea network forms a covalent bond to said active hydrogen(s) in the substrate. The new substrate material is environmentally acceptable and cost effective, has adequate mechanical and chemical properties and enables the hydrophilic coating to be adequately adhered.
    • 公开了一种医疗装置,其包括基底,其表面上至少有一部分具有亲水性表面层,当润湿流体润湿时,其提供医疗装置的低摩擦表面特性。 基底由包含聚烯烃和具有活性氢分子(如聚酰胺或聚氨酯)的组合物的聚合物共混物制成。 亲水性表面层优选通过聚脲网络粘合到基底上,由此所述聚脲网络与基底中的所述活性氢形成共价键。 新的基底材料是环境可接受的并且具有成本效益,具有足够的机械和化学性质,并且能够使亲水涂层充分粘附。

    • A method of dynamic authentication configuration that adjust authentication configuration according to traffic patterns within a system, such as a cellular communications network. In a network, mobile devices are authenticated based on various events, such as an attach, location update, originated call, etc. According to a first embodiment, one or more authentication configuration profiles is defined for a VLR/SGSN and a time schedule/table to automatically update the authentication configurations based on a time. Accordingly, the number authentications for a particular VLR is reduced as signaling traffic increases, and vice versa. In another exemplary embodiment, an HLR monitors system level traffic load to command each VLR and SGSN to change the authentication configurations. Authentication operations are preferably configured on per node and per traffic pattern basis.
    • 一种动态认证配置的方法,其根据诸如蜂窝通信网络的系统内的流量模式来调整认证配置。 在网络中,移动设备基于诸如附件,位置更新,发起呼叫等各种事件进行认证。根据第一实施例,为VLR / SGSN和时间表/时间表定义一个或多个认证配置简档, 表根据时间自动更新身份验证配置。 因此,特定VLR的号码认证在信令业务增加时减少,反之亦然。 在另一个示例性实施例中,HLR监视系统级业务负载,以命令每个VLR和SGSN改变认证配置。 优选地,每个节点和每个业务模式配置认证操作。
