  • Patent number: 8504493
    Abstract: A self-organizing computing machine utilizes a method for mapping from a plurality of patterns contained within provided inputs to an invariant perception, distinguishable by a name or a label. The self-organizing computing machine includes a network of at least three nodes arranged in at least two hierarchical levels, at least one feature extractor, and at least one output unit arranged to interface the invariant perception. The nodes may include a reinforcement learning sub-network combined with an ensemble learning sub-network. The reinforcement learning sub-network may be arranged to receive at least two correlants, to determine a plurality of output values and to output the output values to the nodes of the higher level and the nodes of the lower level. Also, the ensemble learning sub-network may be arranged to receive and to combine output values from nodes of the higher level and nodes of the lower level.

  • Patent number: 8366063
    Abstract: A method of locking of and a directionally adjustable mount including a first plate arranged to stabilize an anisotropic device, a second plate arranged to engage the first plate and provide a support, a second supporting member arranged to engage the second plate and to rollably support the first plate so as to define a local spacing between the plates, and a first supporting member arranged to have a first axis of symmetry and to contact the first plate and engage the second supporting member. In a locked position, the supporting members are arranged coaxially regarding the axis of symmetry, such that a sum of a positioning force applied by the first supporting member and a locking force applied by the second supporting member upon the first plate substantially vanishes, so that a resulting local moment of force oriented to deform the at least one first plate also substantially vanishes.

  • Patent number: 8144312
    Abstract: A telescope with internal scanner utilizing either a single optical wedge scanner or a dual optical wedge scanner and a controller arranged to control a synchronous rotation of the first and/or second optical wedges, the wedges constructed and arranged to scan light redirected by topological surfaces and/or volumetric scatterers. The telescope with internal scanner further incorporates a first converging optical element that receives the redirected light and transmits the redirected light to the scanner, and a second converging optical element within the light path between the first optical element and the scanner arranged to reduce an area of impact on the scanner of the beam collected by the first optical element.

  • Publication number: 20120026497
    Abstract: A polarization switching lidar device, arranged for remote detection and characterization of airborne aggregations of particulates, includes a pulsed laser, a mirror, a polarizing beam splitter, an actively controlled retarder arranged to be controllably alternated between a zero retardation state and a quarter-wave retardation state such that the transmitted portion of the exiting laser light beam is linearly polarized in a predetermined direction when the actively controlled retarder is in the zero retardation state, while being circularly polarized in a predetermined rotational sense when the actively controlled retarder is in the quarter-wave retardation state. A directable telescoping assembly is arranged to collect photons backscattered by the airborne aggregations of particulates and to redirect the collected portion of depolarized backscattered photons onto the polarizing beam splitter.

  • Patent number: 7616293
    Abstract: A system of lasers and detectors to detect the presence of objects and determine their speed is disclosed. The system comprises of a pair of lasers and a pair of detectors focused through a single lens or a pair of lenses. An electronic board that accompanies the lasers and detectors is used to provide the logic and decision making mechanism. Data collected and processed by the system yields such information as whether an object is present, whether the object is stationary or is moving, and subsequent speed information. The described system is also capable of providing additional information concerning the characteristics of the moving object such as its profile and length, and indication of a traffic violation.

  • Patent number: 7323987
    Abstract: A compact system for determining the presence and speed of an object/vehicle, and its application for Red Light Camera photo-enforcement is disclosed. The disclosed system uses accurate timing, laser radiation in the form of optical pulses, and the scattering effect of optical pulses from the road or vehicle surface to determine the presence of a vehicle, and estimate its speed. The system can determine whether an object/vehicle is present at a specific location, estimate its height, and in the case that the object/vehicle is moving, the system can estimate its speed. Combining the disclosed technology with commercially available digital recording techniques and equipment, a traffic photo-enforcement system can be constructed. The system is capable of monitoring traffic in an intersection/highway, measure vehicle speed, identify potential traffic violations, and trigger a visual recording device such as a camera or video system for documenting a violation.
