The invention relates to a method intended to automatically create a description of a video sequencei. The initial challenge includes one or more of one or more objects, one or more indicative answers, and one or more questions based on the one or more objects. Alternatively, two electromagnetic clutches are provided to engage the forward or reverse gear with the propeller shaft, and the controller controls operation of the electromagnetic clutches in response to the instruction to shift such that corresponding one of the forward and reverse gears is engaged with the propeller shaft. Instruction padding or program padding may be used to create instruction encodings of lengths. The mobile information device may further include an application management system that allows one or more object-oriented object classes to allow input and output data to be communicated between Java MIDlets in different MIDlet Suites and between non-MIDlet applications. The compositions can be used in the form of an injectable gel, an injectable paste, a paste, a putty, or a rehydratable freeze-dried form.
