Patent number: 8930959Abstract: Data from one or more sensors is input to a workflow and fragmented to produce HyperFragments. The HyperFragments of input data are processed by a plurality of Distributed Experts, who make decisions about what is included in the HyperFragments or add details relating to elements included therein, producing tagged HyperFragments, which are maintained as tuples in a Semantic Database. Algorithms are applied to process the HyperFragments to create an event definition corresponding to a specific activity. Based on related activity included in historical data and on ground truth data, the event definition is refined to produce a more accurate event definition. The resulting refined event definition can then be used with the current input data to more accurately detect when the specific activity is being carried out.Type: GrantFiled: May 29, 2014Date of Patent: January 6, 2015Assignee: Orions Digital Systems, Inc.Inventor: Nils B.

Patent number: 8752073Abstract: Data from one or more sensors are used to detect an event corresponding to an activity by a person. The detection of the event is then used to loosely model the event to produce an initial event definition. The initial event definition is used in searching historical sensor data to detect other prospective occurrences of the event. Based on the detection of these additional occurrences, the event definition is refined to produce a more accurate event definition. The resulting refined event definition can then be used with current sensor data to accurately detect when the activity is being carried out. For example, the activity may be the use of a video imaging device for cheating, and a casino can use the refined event definition with video imaging to detect when people are using the video imaging device for such purposes.Type: GrantFiled: May 14, 2012Date of Patent: June 10, 2014Assignee: Orions Digital Systems, Inc.Inventor: Nils B.

Patent number: 8395546Abstract: A receive only smart antenna with a command pointing option for communicating with geostationary satellites that autonomously detects the directions from which desired signal are received, and steer the multiple beams accordingly. An array feed is used to illuminate a parabolic reflector. Each feed element of the receive only smart antenna is associated with a unique beam pointing direction. As a receiver is switched to different feed elements, the far-field beam is scanned, making it possible to track a geostationary satellite in a slightly inclined orbit. This eliminates the need for mechanical tracking and maintains high antenna gain in the direction of the geostationary satellite. The receive only smart antenna also features capabilities to form multiple simultaneous beams supporting operations of multiple geo-satellites in closely spaced slightly inclined orbits. The designs can support orthogonal beams for enhanced bandwidth capacity via multiple beams with excellent spatial isolation.Type: GrantFiled: February 9, 2011Date of Patent: March 12, 2013Assignee: Spatial Digital Systems, IncInventor: Donald C.

Patent number: 8232918Abstract: An advanced multiple-beam GPS receiving system is achieved that is capable of simultaneously tracking multiple GPS satellites independently, detecting multiple interference signals individually, and suppressing directional gain in the antenna pattern of each beam in the interference directions. The GPS receiving system can be used for both planar and non-planar receiving arrays, including arrays that are conformally applied to the surface of a platform such as an aircraft. The GPS receiver combines spatial filtering and acquisition code correlation for enhanced rejection of interfering sources. Enhanced gain in the direction of GPS satellites and the ability to shape the beam patterns to suppress gain in the direction of interfering sources make the GPS receiving system largely insensitive to interfering and jamming signals that plague conventional GPS receivers.Type: GrantFiled: September 9, 2011Date of Patent: July 31, 2012Assignee: Spatial Digital Systems, Inc.Inventor: Donald Chin-Dong Chang
