  • Patent number: 10462039
    Abstract: This application discloses a neural network that also functions as a packet data network using an MPLS-type label switching technology. The neural network uses its intelligence to build and manage label switched paths (LSPs) to transport user packets and solve complex mathematical problems. This architecture is well suited to interconnect large numbers of processors or computers into a neural network exhibiting advanced intelligence which can be used for complex activities such as managing the power grid. However, the methods taught here can be applied to other data networks including ad-hoc, mobile, Information Centric, Content Centric, Sensor, and traditional IP packet networks, cell or frame-switched networks, time-slot networks and the like.

  • Patent number: 10380816
    Abstract: A method, computer program product, and system are disclosed for facilitating access by a first person to a secure region that is at least partly defined by an access control device. The method acquires, using at least one visual sensor, first image information including the first person and the access control device. The method identifies the first person using image analysis performed on the first image information. The method further identifies a first behavior of the first person relative to the access control device. Upon determining the first behavior corresponds to a predefined visual access behavior indicating that the first person is in the process of manually operating the access control device, and that the security level of the first person satisfies a predetermined threshold security level associated with the access control device, the method permits the first person to physically access the secure region.

  • Publication number: 20070182062
    Abstract: A method of forming a filter unit comprised of a filter element and an encircling peripheral encasement frame to which the filter element is sealed. The frame is moulded in situ by solidification of a liquid, solidifiable moulding composition (e.g. a curable resin or a matter thermoplastic resin that solidifies on cooling) provided around the periphery of the filter element. The method may comprise the steps of: (i) providing a filter element having front and rear faces and a bounding peripheral edge, (ii) locating around the peripheral edge of the element a mould unit which seals against peripheral regions of the front and rear faces and which together with the peripheral edge defines a mould cavity, (iii) filling the mould cavity with a solidifiable, liquid moulding composition, (iv) effecting conversion of the liquid to a solid, and (v) removing the mould thereby producing the filter element.

  • Publication number: 20070181688
    Abstract: An arrangement for determining light beam position in an electro-optical reader, image projector and like devices includes a drive for moving a scanning light beam at a scan frequency across a target as a scan line, and an electro-optical feedback assembly operatively connected to the drive, for optically detecting scan line position during beam movement, and for generating a feedback signal at the scan frequency, the feedback signal being indicative of the scan line position. A feedback coil in the drive is eliminated to avoid electromagnetic coupling between multiple coils in the drive.

  • Publication number: 20060279663
    Abstract: A lightweight, compact image projection module, especially for mounting in a housing having a light-transmissive window, is operative for sweeping a composite laser beam as a pattern of scan lines on a planar projection surface and for causing selected pixels arranged along each scan line to be illuminated to produce an image, especially in color. The raster pattern extends along mutually orthogonal directions that are generally parallel to mutually orthogonal dimensions of a support of the module. The image is level with the horizontal.

  • Publication number: 20060244924
    Abstract: Crosstalk between a drive coil and a primary feedback coil is eliminated by positioning a secondary feedback coil in proximity with the drive coil for contamination by the crosstalk to the same extent as the primary feedback coil, and by processing feedback signals generated by the feedback coils to cancel the crosstalk. The drive coil is used to oscillate a scan mirror employed in an image projection arrangement or an electro-optical reader.

  • Publication number: 20060153558
    Abstract: A method and apparatus are provided to capture images using a laser projection display (LPD). In a full color LPD camera, three lasers (red, blue, and green) are deployed to scan an image and receive reflected laser light therefrom. The reflected laser light may be analyzed and assembled into a picture. The LPD may also be used to display the picture, to operate as a viewfinder, to print the picture, to operate as a range finder, and the like.

  • Publication number: 20060126023
    Abstract: An image projection system projects an image on a projection screen having a phosphor for converting incident violet light into green light which, together with red and blue light, creates the image in full color. The screen includes an apertured mask having apertures filled with the phosphor, or a phosphor plate in contact with the mask and having lenslets extending through and past the apertures.

  • Publication number: 20060087628
    Abstract: A plurality of image projection modules is operative for causing selected pixels in overlapping raster patterns to be illuminated to produce a large size image of high resolution of VGA quality in monochrome or color. The selected pixels in an overlap region of the patterns are illuminated at a lesser intensity to provide uniform brightness over the image. Multiple single mode lasers, or a multimode laser with an aperture stop, are employed to increase laser output power. Speckle noise is reduced by controlling the optical transmission characteristic of a projection screen. Three-dimensional images are generated by moving the screen. Cross-coupling between drive and feedback mechanisms in image projection is reduced for better image quality.

  • Publication number: 20050279922
    Abstract: A method and apparatus are provided to controllably compensate for distortions in an image produced by an LPD, where the distortion arises from the shape and/or angle of the viewing surface relative to the LPD. For example, the LPD can determine the angle of the viewing surface relative to the LPD and then adjust the horizontal and vertical scan mechanisms to return the image to its original configuration, such as rectangular.

  • Publication number: 20050175048
    Abstract: A method and apparatus are provided to controllably reduce power of a laser projection display (LPD) in response to detecting a variation in a viewing surface. During the operation of the LPD, a controller 142 monitors laser light being reflected from the viewing surface. Since the controller 142 “knows” the amount of power that the LPD is being instructed to deliver, it may compare the known power to the reflected laser light to determine if a foreign object may be in the path of the laser light, and therefore, affecting the magnitude of the laser light. The controller 142 responds to detecting such an event by reducing power to the lasers.

  • Publication number: 20050168728
    Abstract: A method and apparatus are provided to compensate for variations in the alignment of a plurality of lasers 102, 104, 106. A controller 142 varies the time at which the lasers 102, 104, 106 are energized so that the laser light emitted therefrom is reflected from a scanning mirror 118 at varying times so that each of the beams of light is reflected along a substantially common path and delivered to a substantially common point.
