    Abstract: A light amplifier includes a source of multiple light beams, each modulated with the same information, and a plurality of light amplifying optical fibers, each amplifying one of the light beams. The amplified light from each amplifying fiber is converted to electric form, and the electrical signals are summed to add the information and average the noise. In one embodiment, the bundle of fibers is twisted as it is wound about a cylinder, to average the compressive and tension forces on the fibers of the bundle. In another embodiment, a common cladding surrounds a bundle of fibers.

    Abstract: A method of operating a mobile robot to traverse a threshold includes detecting a threshold proximate the robot. The robot includes a holonomic drive system having first, second, and third drive elements configured to maneuver the robot omni-directionally. The method further includes moving the first drive element onto the threshold from a first side and moving the second drive element onto the threshold to place both the first and second drive elements on the threshold. The method includes moving the first drive element off a second side of the threshold, opposite to the first side of the threshold, and moving the third drive element onto the threshold, placing both the second and third drive elements on the threshold. The method includes moving both the second and third drive elements off the second side of the threshold.

    Abstract: Detecting an object using sound waves includes outputting a sound wave from a transducer, receiving an echo after outputting the sound wave, obtaining a threshold value based on the echo and plural other echoes that are within a predetermined range of the echo, and determining if the echo is a result of the sound wave based on the threshold value.
