Abstract: On-the-go fingerprint scanners and methods of capturing fingerprints on-the-go are disclosed. In some aspects, the on-the-go fingerprint scanner can include a scanning area and a beam break sensor disposed coincident to the scanning area such that the beam break sensor detects when an object passes through the scanning area. The scanner can also include at least one hand camera configured to capture a video image of the scanning area such that when the beam break sensor detects that an object has passed through the scanning area, the hand camera detects whether the object is a human hand and the location of any fingers on said hand, and at least one fingerprint camera configured to receive the location of any fingers within the scanning area from the hand camera and capture a high-resolution image of at least a portion of any of said fingers passing through the scanning area.

Abstract: A method for stabilizing a load suspended with a rope, cable, net, sling or the like is disclosed. A beacon having a plurality of lights thereon may be attached to the load relative to the attachment point to the load, to an attachment point of the load or to the rope, cable sling or the like. A sensor on the lifting device senses the beacon and thus any swinging motion of the load, and a processor responsive to the sensor develops control signals that direct motion of the lifting device to dampen any swinging motion of the load.

Abstract: A contactless fingerprint acquisition and processing method, includes detecting and acquiring an object image, converting the object image into a fingerprint image and at least one of identifying and verifying the fingerprint image.

Abstract: Exemplary embodiments include an agile non-contact biometric sensor apparatus, having a sensor that monitors a field of view for a user, an imaging system that captures one or more pieces of biometric information from the user, and a pan-tilt device that orients the imaging system to a location of the user in the field of view detected by the sensor.

Abstract: A system is disclosed for remotely determining 6 degree of freedom of an object. Four or more radiating beacons are placed on an object, the beacons each simultaneously radiating a synchronized repeating code, the code being different for each beacon. A position sensor, such as a quadrant detector, receives the light signals from the beacons, and correlates the received beacon signals against the same signal sequences produced in the receiver. With orientation of the beacons on the object being known, and orientation of the quadrant detector, or receiver, being known, roll, pitch, yaw, and X, Y and Z position in a coordinate space of the object can be determined.

Abstract: A contactless fingerprint acquisition and processing method, includes detecting and acquiring an object image, converting the object image into a fingerprint image and at least one of identifying and verifying the fingerprint image.

Abstract: A system for recognizing objects in images, and using that recognition to solve mission problems, such as identifying, tracking, and reporting movement of mobile military targets of interest. The system incorporates preprocessor and postprocessor with an image correlator, control systems, and feedback loops functioning with a real-time operating system. Tracking includes correlating patterns in an image stream so as to monitor image changes that represent changes of location, shape, trends, or other attributes. Reporting may entail visual displays of correlation results, or other data outputs suitable for steering gimbaled sensors, aiming weapons, or for other functions. The instant invention has application in numerous areas where recognition and tracking of patterns and trends are desired in imagery or in other two-dimensional representations of data.

Abstract: Methods for using training images to define correlation strength surfaces about reference filters, permitting direct solution of position and orientation using images of a target object with only a few reference filters are disclosed. Correlations of selected reference filters with training images are used to develop expressions describing shapes of respective correlation surfaces at incremental changes relative to an aspect or range used for a filter. Correlations of target images with only a few reference filters may then be used to define target orientation and range in many real-world applications. A method for determining target object orientation and/or range based on interpolations, using results of correlations of a target image with composite filters having reduced sensitivities for different orientation axes, or range, is also disclosed. Techniques for using training images to create such composite filters are disclosed, as are extensions of methods to additional dimensions.
