A lacrosse head comprising a frame, a pocket attached to the frame, and at least one energy absorbing element engaging the frame to absorb energy from an impact to the pocket. In one aspect, a MEMS resonator device includes a substrate, an electrode including a first microstructure supported by the substrate, a resonant element including a second microstructure spaced from the first microstructure by a gap for resonant displacement of the second microstructure within the gap during operation, and a disabled shunt coupled to the electrode or the resonant element. Thus, the backlight 7, and a liquid crystal display device 1 employing it, permits light to emerge therefrom within a desired range of viewing angles while offering high brightness within that range, with reduced degradation of viewability.
