    • Embodiments of the present invention comprise biodegradable composites including a polyurethane component and cells encapsulated in gel beads, as well as methods of making such composite and uses thereof. In certain embodiments the gel beads are alginate beads. The composites may be moldable and/or injectable. After implantation or injection, a composition may be set to form a porous composite that provides mechanical strength, supports the in-growth of cells, and/or delivers cells to particular tissues. Inventive composites have the advantage of being able to fill irregularly shaped implantation sites, deliver cells in a localized and noninvasive manner, and optimize cell proliferation and differentiation of delivered cells.
    • 本发明的实施方案包括包含聚氨酯组分和包封在凝胶珠中的细胞的生物可降解复合材料,以及制备这种复合材料及其用途的方法。 在某些实施方案中,凝胶珠粒是藻酸盐珠粒。 复合材料可以是可模塑的和/或可注射的。 在植入或注射后,可以将组合物设置成形成提供机械强度的多孔复合材料,支持细胞的生长和/或将细胞递送到特定组织。 本发明的复合材料具有能够填充不规则形状的植入位点,以局部和非侵入性方式递送细胞并优化递送细胞的细胞增殖和分化的优点。

    • The present invention relates to a communication system. The communication system includes a handheld communication device, a primary communication module, and a secondary communication apparatus. The primary communication module is configured for communicating with the secondary communication apparatus within a predetermined coverage area. When receiving a short message signal, the handheld communication device broadcasts a search signal. The secondary communication apparatus detects the search signal and sends a response signal to the handheld communication device according to the user's operations. The handheld communication device detects whether the response signal is received and processes accordingly. The present invention also provides a method of applying a security function for short messaging adapted for supporting the aforementioned communication system.
    • 本发明涉及通信系统。 通信系统包括手持通信设备,主要通信模块和辅助通信设备。 主通信模块被配置为在预定覆盖区域内与次通信设备进行通信。 手持通信设备收到短消息信号时,广播搜索信号。 次要通信装置检测搜索信号,并根据用户的操作向手持通信装置发送响应信号。 手持通信设备检测响应信号是否被接收并相应地进行处理。 本发明还提供一种应用适于支持上述通信系统的短消息的安全功能的方法。
