摘要： A method for enhancing the fairness and performance in a multihop ad hoc network, the method usually including providing contention synchronization information regarding a transmission between nodes of the network, wherein the information is routinely provided to nodes in a range of two hops from the nodes participating at the transmission. The method also typically includes setting, after successfully finishing the transmission, a waiting time for the nodes participating at the transmission, in which these nodes backoff from accessing a transmission medium.

In one aspect, the display devices can include an annular diffuser that is configured to scatter light into a ring shaped region. The annular diffuser can include a plurality of axicon lenses or holographic features. The reflective display can include an annular diffuser to shift the direction along which most of the modulated light is scattered away from the direction along which light is specularly reflected by the display devices to reduce specular glare and enhance brightness and/or contrast ratio.

摘要： This disclosure provides systems, methods and apparatus related to an electromechanical display device. In one aspect, an analog interferometric modulator includes a display pixel having a movable reflector, and a movable absorbing layer. The movable absorbing layer is positionable at a variable first distance from an electrode that is substantially transparent over a visible wavelength spectrum. The movable reflector is positionable at a variable second distance from the movable absorbing layer. Changing the first distance and the second distance changes a characteristic of light reflected from the display element.
