20150181682 | BYPASS CIRCUIT FOR NEUTRAL-LESS CONTROLLER IN LIGHTING CONTROL SYSTEM - A device provides a bypass path for leakage current of a neutral-less controller in a lighting control system for selectively supplying line voltage to a load. The device includes a dummy load, a voltage sensor, a bypass switch, a switch controller and a delay timer. The voltage sensor senses line voltage at an output of the neutral-less controller. The bypass switch selectively connects the dummy load in parallel with the lighting load. The switch controller activates the bypass switch to connect the dummy load in parallel with the lighting load when the line voltage is low, providing a bypass path for the leakage current, and deactivates the bypass switch after a delay period to disconnect the dummy load from being in parallel with the lighting load when the line voltage is high. The delay timer implements the delay period in response to the line voltage transitioning from low to high. | 06-25-2015 |

20100008540 | Method for Object Detection - A method for object detection from a visual image of a scene. The method includes: using a first order predicate logic formalism to specify a set of logical rules to encode contextual knowledge regarding the object to be detected; inserting the specified logical rules into a knowledge base; obtaining the visual image of the scene; applying specific object feature detectors to some or all pixels in the visual image of the scene to obtain responses at those locations; using the obtained responses to generate logical facts indicative of whether specific features or parts of the object are present or absent at that location in the visual image; inserting the generated logical facts into the knowledge base; and combining the logical facts with the set of logical rules to whether the object is present or absent at a particular location in the scene. | 01-14-2010 |
20100278420 | Predicate Logic based Image Grammars for Complex Visual Pattern Recognition - First order predicate logics are provided, extended with a bilattice based uncertainty handling formalism, as a means of formally encoding pattern grmmars, to parse a set of image features, and detect the presence of different patterns of interest implemented on a processor. Information from different sources and uncertainties from detections, are integrated within the bilattice framework. Automated logical rule weight learning in the computer vision domain applies a rule weight optimization method which casts the instantiated inference tree as a knowledge-based neural network, to converge upon a set of rule weights that give optimal performance within the bilattice framework. Applications are in (a) detecting the presence of humans under partial occlusions and (b) detecting large complex man made structures in satellite imagery (c) detection of spatio-temporal human and vehicular activities in video and (c) parsing of Graphical User Interfaces. | 11-04-2010 |
