    摘要: For an example embodiment, a method for a communication device operating in a synchronous communication system is described. The method includes performing a listen-before-talk (LBT) procedure prior to the start of a downlink subframe of a synchronous frame and determining if a transmission from another communication device of another communication system is detected during the LBT procedure. In the case that a transmission is detected during the LBT procedure, the communication device refrains from transmitting during the downlink subframe. In the case that a transmission is not detected during the LBT procedure, the communication device transmits during the downlink subframe.

    摘要: A system and method for automated determination of position and movement of a contact lens with respect to a subject wearer's eye based upon a complimentary pair of images, acquired in rapid succession, in which one image of the pair is acquired using light that allows viewing of the pupil and/or limbus through the lens and the other image is acquired using light that is absorbed by the lens to generate an opaque image with a defined edge relative to the surrounding sclera. The images of the pair are acquired in close enough temporal proximity to ensure that eye movement in the interval therebetween is insignificant and both images are in the same approximate reference frame. Thus, the location of the pupil and limbus in one image can be accurately compared with the location of the contact lens edge in the other image.
