    The system \(u'+\nabla \Phi (u)=e(t)\) with \(u\:\mathbb R\to \mathbb R^N\), \(\Phi \:\mathbb R^N\to \mathbb R\) (\(\Phi \) convex), and \(e\:\mathbb R\to \mathbb R^N\) is considered. Necessary and sufficient conditions for the existence and uniqueness of bounded or almost-periodic solutions are given.
