Systems and methods for providing the progressive download of media content using techniques that preferentially identify and use periods of surplus network capacity to maintain the content delivery. The electrical terminal defines a mating portion and a mounting portion, the mounting portion carrying a crimp member having crimp teeth configured to pierce through a flex cable when crimped so as to mount the flat flex cable to the mounting portion of the electrical terminal. The outlet port is spaced from the inlet port so that liquid flows through the interior space of the housing from the inlet port to the outlet port. A leaf spring ensures opening of the chamber when the base circle of the cam is next reached. This avoids perceived slow start-up and unresponsiveness associated with interpretation or compilation of generic code representation at the execution apparatus. In a printed wiring board 2, a distance D between wiring patterns 81 and 85 disposed so as to oppose each other is the smallest at a position nearest to a center point of an LED chip 14 disposed at a designed location, and increases with an increasing distance from the point G.
