Abstract: The present disclosure describes a container for placing an object therein. The container includes a container body and a lid over the container body, a collision-preventing portion attached to one or more of the container body and the lid and configured to buffer an impact force, a pairing recognition mechanism configured to detect an object placed in the container body, and a liquid-detecting sensor configured to detect a leakage from the object.

Abstract: A car A/V playback device includes at least a signal-processing unit for compressing and storing input A/V signals as well as decompressing and reproducing stored A/V signals; a data-access unit allowing the signal-processing unit to do real-time access of signals stored therein; and a control unit for controlling modes in which the signal-processing unit and the data-access unit process signals. The car A/V playback device can be connected to a personal computer or a cable television to download a large quantity of musical works existed in the form of MP3 or CD, television programs, and pictures stored on VCD and DVD for storage on the device and direct playback on a car without the need of mounting VCD and DVD players on the car.
