Abstract: A device for applying compressive therapy is disclosed. According to one embodiment, the device has a top layer and a bottom layer adapted to contact a body surface of a user. The device further includes a compressive element disposed between the top layer and the bottom layer, where the compressive element is configured such that, upon activation of the compressive element: (i) a compressive force is applied to the body surface and (ii) the compressive element curves to more closely conform to the bottom layer.

Abstract: Lasers, such as in laser structures, can include two or more semiconductor structures that are substantially identical or that include the same semiconductor material and have substantially the same geometry, such as in closely spaced dual-spot two-beam or quad-spot four-beam lasers. The lasers can also include differently structured current flow or contact structures or different wavelength control structures. For example, current flow or contact structures can be differently structured to prevent or otherwise affect phase locking, such as by causing different threshold currents and different operating temperatures.
