Abstract: A system for identifying and authenticating an object includes an indicium having randomly applied fluorophores that emit light when excited. The fluorophores produce a unique, random pattern that uniquely identifies any object to which the indicium is attached. The indicium may also include an identification code. An imaging unit with a flash excites and captures the photo-luminescence of the indicium in the form of a random image. The identification and authentication of the object is done by sending the image captured via a mobile phone or other device such as a laptop or notepad to a server of an authentication unit via the Internet or other communication media to correlate with a reference image of the indicium captured at the time of manufacture. This assures the authenticity of the product with a high degree of confidence.

Abstract: The invention provides an authentication unit for reading identification and/or authentication information from a tag or object. The authentication unit includes a near-field reader configured to read a first identification feature based on inherent disorder, and a far-field reader configured to read a second identification feature, such as a bar code, optical characters, or an RFID tag. The near-field and far-field readers may be combined in a single integrated scanning module, which also includes circuitry for receiving signals from the readers, and an interface for communicating with a host device.

Abstract: The present invention relates to particulate based compositions for deposition on substrates, a system and method for the deposition of the said compositions for preparation of a clone-proof monetary and/or security documents. The said composition is applied as an identifier at predetermined location on the substrate. The magneto-optical signal from the said applied composition is captured by the reading system. Further it is encrypted same as an invisible or visible two dimensional (2D) barcode/image on the substrate as an associated identifier so as to create a dedicated, non repeatable and unique functional digitized relation between two said identifiers and/or any other identifier(s) linked to a specific object.

Abstract: Embodiments of the invention provide an adaptor that presents information from an inherent disorder feature as an optical signal. The adaptor is configured to direct the optical signal onto an optical processing unit built into a camera of a mobile device, such as a mobile telephone, to generate an image usable to identify an object. The adaptor is configured to be user attachable to the mobile device.

Abstract: A method comprises a step of obtaining an identification code of a product, a step of receiving a physical location of the product from a buyer, a step of noting geographical locations seller(s) of the product in the vicinity of the physical location of the product, a step of comparing the geographical location with the physical location, and a step of recording a sales transaction of the product if the geographical location is away from the physical location more than a predetermined distance.

Abstract: A system to generate a template of a fingerprint input image is described. The system provides for smoothing the input image, forming a binary image from it, and further processing the binary image to extract the minutia of the fingerprint. The minutiae are stored in the template, in the form of locations of each minutia in relation to all other minutiae. The system includes optional identification and verification steps, which compare the template generated according to the system with templates stored in a fingerprint database.

Abstract: A laser projection device suitable for displaying full color images is disclosed. The LPD includes a variety of techniques for modulating laser beams produced by one or more lasers with image data to controllably produce the image using a modified raster scan.

Abstract: Multi-tier system for digital radio communication. The multi-tier system has a first-tier base station with relatively long-range radio and has a second-tier base station with relatively short-range, low power and cheaper radios. The system can be more versatilely configured to meet demands of various applications. The application may include data capture using bar code readers, radio frequency readers and other automatic data capture devices. The system may also be used to control hotel door locks, individual room temperature control, remote video monitoring—all without having to wire and with much flexibility given the two types of radios employed.

Abstract: A method and apparatus are provided to controllably reduce power of a laser projection display (LPD). Light is scanned from a laser onto a viewing surface to produce an image thereon, and power used by the laser is reduced used while scanning at least a portion of the viewing surface.

Abstract: A laser projection device (LPD) suitable for displaying color images is disclosed. The LPD is used to excite various photoluminescent materials located on a display screen so as to produce multi-color displays. Additionally, the screen may be movably mounted so as to reduce laser speckling.

Abstract: A method and apparatus are provided for controlling the operation of a Laser Projection Display (LPD). Generally, the LPD is comprised of a laser, an optical system and a controller. The laser is adapted to emit a beam of laser light. The optical system is adapted to scan the beam of laser light on a display surface in a two-dimensional raster pattern. The controller is adapted to control the rate at which the laser beam is scanned to produce regions of varying resolution on the display surface. The controller is also adapted to present laser light onto the display surface within only selected portions of the two-dimensional raster scan pattern so that spaced apart image regions may be created.

Abstract: A lightweight, compact image projection module, especially for mounting in a housing having a light-transmissive window, is operative for causing selected pixels in a raster pattern to be illuminated to produce an image of high resolution of VGA quality in color.

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.

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.
