Abstract: Provided are larders systems, aircraft equipped with such systems, and methods of operating such systems. A larder system includes at least two larder cases removably disposed in the same compartment of a larder enclosure. The two cases are detachably interlocked with each other such that removal of the outer case from the enclosure advances the inner case closer to the opening. After the removal of the outer case, the inner case may be retained at the opening. The two cases may be interlocked when pushed against each other, such as when the outer case is inserted into the compartment containing the inner case. In some embodiments, a larder case may be interlocked with the larder enclosure or one of its components, such as a door. This enclosure interlocking allows for the larder case to retain its interlocked position when, for example, the enclosure is only partially filed.

Abstract: A tracking method for embedded systems is disclosed. A stacking way is used for viewing and tracing. In the beginning, a program counter (PC) and a stack segment of a function are found out. Then an instruction of the function is learned according to the stack segment and further stack size of the function is calculated. In accordance with the stack size, a stack frame is viewed to find out a recursive program counter of a previous function. Next according to the recursive program counter, an entry point of the previous function is calculated. Therefore, the system knows the memory block is required by which function and further finds out what causes computer shut-down or program errors. Moreover, stack status before the error occurred in the stack frame is got so as to get a returning path that enables the processor going back to status before the error occurred.
