Abstract: Systems, apparatuses, and methods for autonomously estimating the position and orientation (“pose”) of an aircraft relative to a target site are disclosed herein, including a system including a plurality of beacons arranged about the target site, wherein the plurality of beacons collectively comprise at least one electromagnetic radiation source and at least one beacon ranging radio, a sensor system coupled to the aircraft including an electromagnetic radiation sensor and a ranging radio configured to determine a range of the aircraft relative to the target site, and a processor configured to determine an estimated pose of the aircraft based on at least: (i) detected electromagnetic radiation, and (ii) time-stamped range data for the aircraft relative to the target site.

Abstract: A method for sensing an optical image and producing an improved image signal, includes the steps of: supplying a first signal to a first plurality of nodes, the nodes residing in an integrated circuit substrate; producing a second signal at a second plurality of nodes residing in the integrated circuit substrate, the first plurality of nodes substantially corresponding to the second plurality of nodes, wherein the step of producing the second signal includes: imposing a smoothness constraint on the second signal restricting a signal difference between the nodes of the second signal, the smoothness constraint imposed with a plurality of horizontal electronic element; imposing a closeness constraint on the second signal, thereby restricting a signal difference between the corresponding nodes in the first signal and the second signal, the closeness constraint imposed with a plurality of vertical electronic element; and balancing the smoothness constraint and the closeness constraint with a balancing means contro

Abstract: The present invention provides an image processing method. In one embodiment, the method provides discontinuity-preserving image smoothing and segmentation, noise reduction, reduction of image variations particularly those variations caused by illumination conditions, exposure compensation, and dynamic range compression. The present invention also provides an electronic image sensor that is able to detect high dynamic range optical images and produce electronic images with reduced dynamic range.

Abstract: A method of encoding identity of events comprises: receiving an event bit pattern having bits representative of events, and determining a code from the event bit pattern, said code containing the information for recovering identity of events when one or more events are simultaneously present in the event bit pattern.
