The present application discloses a CPU interconnect apparatus and system, and a CPU interconnect control method and control apparatus. The CPU interconnect apparatus includes two gating units and one first intermediate line. Each gating unit includes a first terminal and a second terminal. The first terminal is connected to the second terminal when the gating unit is in a first state. The first terminal is disconnected from the second terminal when the gating unit is in a second state. The two first terminals of the two gating units are connected to two CPUs in a first node. The two second terminals of the two gating units are connected to two ends of the first intermediate line, or the two second terminals of the two gating units are configured to connect to two CPUs in a second node.

A smart terminal information display method and a smart terminal, the smart terminal information display method may include a smart terminal detecting an inputted locking event to lock its screen, responding to the locking event and displaying the information containing a list of specific functions on the screen, and entering the locking screen interface. Embodiments enable a user to easily acquire new function information of the smart terminal and improves the user experience, but also makes a full use of the locking screen background of the smart terminal and expands the functions of the smart terminal, thereby further improving the user experience.

A switching element that is at least partially implemented in one or more printed wiring boards (PWBs). A plurality of inputs and a plurality of outputs may be integrated into the PWB(s). In some embodiments, a plurality of contact bars may also be comprised in respective contact bar pockets bounded at least partially ab at least one of the PWB(s). The switching element is selectively operable in first and second states, the first state in which at least one contact bar couples one of the plurality of inputs to one of the plurality of outputs such that an analog signal input to the respective input is routed to the respective output and the second state in which at least one contact bar is held in an off state.
