20100021052 | System and method for generating a terrain model for autonomous navigation in vegetation - The disclosed terrain model is a generative, probabilistic approach to modeling terrain that exploits the 3D spatial structure inherent in outdoor domains and an array of noisy but abundant sensor data to simultaneously estimate ground height, vegetation height and classify obstacles and other areas of interest, even in dense non-penetrable vegetation. Joint inference of ground height, class height and class identity over the whole model results in more accurate estimation of each quantity. Vertical spatial constraints are imposed on voxels within a column via a hidden semi-Markov model. Horizontal spatial constraints are enforced on neighboring columns of voxels via two interacting Markov random fields and a latent variable. Because of the rules governing abstracts, this abstract should not be used to construe the claims. | 01-28-2010 |

20110296699 | Automatic Bow Sighting Device with Range Finding Means - Disclosed is an archery bow sighting device that incorporates a laser range finder, an automatically adjusting sight pin, trigger control and distance indicator. The device incorporates imbedded electronics and a gearing mechanism to adjust a sighting pin based on distance to target and calibrated distance data. The user aims the laser range finder at a designated target for determination of its distance, after which the sight pin is automatically adjusted to account for the distance and is used to aim at the target. To accurately aim the range finder, a peep sight along the length of the bow string is aligned with crosshairs within the range finder while aiming at the intended target. A trigger button along the bow pulses the laser range finder to determine distance, and the sighting pin elevation is updated accordingly by the imbedded electronic circuit and interpolation of preset distances. The device is attachable to any archery bow sight rail, and provides a means to quickly update a range to target if the target is mobile. A trigger button controls the device in use, while power is supplied by a user harnessed battery pack and wire tether. | 12-08-2011 |
