摘要： A heart-shaped self-locking button includes one housing and one push rod. The push rod is slidably arranged within the housing. A heart-shaped structure is formed on the push rod. The button includes one pin and one flexible element. One end of the pin is fixed on the housing, while the other end is fitted with the heart-shaped structure. The flexible element is arranged between the housing and the push rod and presses the pin towards the heart-shaped structure to allow the pin to be in constant contact with the heart-shaped structure. The heart-shaped structure is arranged on the push rod. Also, the flexible element between the housing and the push rod is utilized to press the pin towards the heart-shaped structure on the push rod to allow the pin to be in constant contact with the heart-shaped structure when moving.

摘要： Improved systems and methods for call and call feature setup, administration and processing on PSTN and other telecommunications networks are provided. Calls are set up on a service plane of a conceptual switch that includes a switch plane, control plane, and service plane that are analogous to the OSI layered model of networks including a physical layer, network layer and application layer. Call set-up logic is separated from the switching fabric, allowing for flexible, on-demand, modification of service options using software while maintaining the same switching fabric in hardware. Call set-up is accomplished by a call request made upon connection of a call to the switch. This causes a call agent to search an eXtensible Markup Language knowledge base to find a web page corresponding to the initiating caller. The Web page may be collocated with the switch or on a LAN with the switch or on the “Web,” even on the caller's termination equipment (telephone).
