An MPEG -4 encodingdecoding method, medium, and system. Liquid material is received through the inlet at a low pressure, and the dispensing module 32 rapidly develops high pressure at the outlet 78 to jet the liquid material from the outlet 78. In one embodiment, the hybrid device also provides a physical interconnect for connecting to other devices to send and receive control signals and data, and receive power. The housings are arranged so that two housings are releasably engagable with one another. A number of the angle points recorded on the information storage medium is computed so that a jumping distance required by the data during reproduction does not exceed a maximum jumping distance of a reproducing apparatus. The invention also relates to a method for driving a gate of such a transistor.
