Abstract: An in-car temperature-controlling device for a car in its parked state uses a wireless remote control to remotely control a power-activating unit, an engine-starting unit, a window-activating unit and an AC-activating unit of the car, so as to adjust the car's in-car temperature. Its installation is easy and needs no structural changes to the car, so the car using the device can, in its parked state, have its in-car temperature prevented from being too high or too low. The in-car temperature-controlling device is characterized in contributing to convenience, safety, comfort and low costs, and is applicable to all existing and newly built cars.

Abstract: Provided are a method and a device of a host with IPv4 application for performing communication. The method of the host with IPv4 application for performing data communication includes the following steps: the IPv4 application generates an IPv4 packet sent to a communication end; when confirming the type of the network the host is located in is an IPv6 network, the host transforms the IPv4 packet head of the IPv4 packet to an IPv6 packet header, and sends it to the communication end via the IPv6 network. With this invention, it can be accomplished that according to the type of the network the host is located in, the host with IPv4 application communicates with a communication end; the processing load of the system is lightened; the probability that invalidation occurs at a single node is reduced; the smooth migration and transition from original IPv4 application to IPv6 system are facilitated.
