Abstract:
The present invention relates to a bidirectional voice transmission system and a method thereof, wherein the system timing of the system is divided into three time slots for carrying a control signal, a broadcast voice signal and a mobile device voice signal. The bidirectional voice transmission system is able to carry out the signal transmission by way of frequency frogging, so as to effectively avoid the signal interference from occurring between any two different signal transmitting and receiving devices. Besides, all of the mobile devices can be added into the bidirectional voice transmission system by way of dynamic building, without using any specific communication interface. The most important is that, the number of node routers can be expanded to about 65,000 in order to apply the bidirectional voice transmission system in a huge range network communication or a wild rescue field.
Abstract:
A nonplanar antenna embedded package structure and a method of manufacturing the same are introduced. The structure includes a nonplanar antenna component. The nonplanar antenna component comprises an antenna substrate, metal wiring, through-hole, and metal bump. The substrate surface covers the metal wiring. The through-hole penetrates the substrate from the antenna substrate bottom side but does not penetrate the metal wiring, and does not affect its appearance. The metal bump is implanted in the through-hole from the antenna substrate bottom side to join the metal wiring. An electronic component having a copper cable is provided. An end of the copper cable protrudes from the electronic component and is inserted into the through-hole of the antenna component to join the metal bump, thereby forming the nonplanar antenna embedded package structure characterized by: preventing the antenna metal wiring from exposing, and reducing interference otherwise arising from antenna resonance frequency and noise.

Abstract:
A crosslinkable polysiloxane molecule is in the form of a polysiloxane polymeric chain with a pendant group, that is, a benzoxazine group, and thus is capable of undergoing a cross-linking reaction spontaneously to produce a crosslinkable polysiloxane polymeric material. The benzoxazine group enhances the compatibility between a polysiloxane polymer and a conventional organic polymeric material, functions as a polymer flame retardant or reaction-oriented additive, and widens the application of a polysiloxane polymer to organic polymeric materials in property adjustment and the applicability of the organic polymeric materials.
