  • Patent number: 10987860
    Abstract: A system and method are provided for implementing relatively low temperature joining processes, including displacement/vibration welding techniques and/or heat staking techniques, in a process of building up laminate layers to form and/or manufacture three-dimensional objects, parts and components in additive material (AM) manufacturing systems. A multi-stage 3D object forming scheme is described involving steps of laminate cutting (with lasers or other cutting devices); laminate transport between processing stations (including using one or more of conveyors, robotic pick and place devices and the like); laminate stacking, clamping and adhering through comparatively low temperature welding or other mechanical joining (including displacement/vibration welding or heat staking); and mechanical surface finishing (via CNC machining or other comparable process).

  • Patent number: 8811664
    Abstract: What is disclosed is a method for vehicle occupancy detection using a single band infrared imaging system. First, an infrared image of a vehicle intended to be processed for human occupancy detection is captured using a single band infrared camera set to a predefined wavelength band. A candidate sub-image is identified within the captured image. A cumulative histogram is formed using the reflectance values of each pixel in the candidate region. A threshold reflectance value is then determined from the cumulative histogram using a pre-defined cumulative occurrence fraction value which corresponds to a value equivalent to an average sized human face. Embodiments for setting the threshold reflectance value are disclosed. Thereafter, human occupants can be distinguished in the image from the vehicle's interior by comparing pixel reflectances in the sub-image against the threshold reflectance value.

  • Patent number: 8611608
    Abstract: What is disclosed is a system and method for determining whether a front seat in a motor vehicle is occupied based on seat pattern recognition. The present invention takes advantage of the observation that an unoccupied seat of a motor vehicle exhibits features which are distinguishable from an occupied seat. An unoccupied motor vehicle seat typically features long contiguous horizontal line segments and curve segments, and substantially uniform areas encompassed by these segments which are not present in an occupied seat. The present method provides a long horizontal edge test which uses location information within a defined window of the image, edge linking, softness of the edge, number of lines, line/curve fitting, and other techniques to locate horizontal edges in the image which define a seat, and a uniformity step which determines whether the area bounded by the horizontal edges is relatively uniform indicating an unoccupied seat.

  • Patent number: 8559050
    Abstract: What is disclosed is a novel system and method to control an imaging device. A first collection of a plurality of two-dimensional image points in a first vector space for a source image and a second collection of a plurality of two-dimensional image points in a second vector space for a target image are received. The first collection of two-dimensional image points and the second collection of two-dimensional image points are converted into a homogenous form to apply affine matrix transformations. A matrix transformation is solved to map the first collection of the plurality of two-dimensional image points to the second collection of the plurality of two-dimensional image points. The matrix transformation is used to adjust distortion of the target image in an imaging device.

  • Patent number: 8412088
    Abstract: This is an alignment system where precise alignment of a reproducible image is obtained with respect to the paper. An imaged paper to be reproduced is placed on a light table having a right angle fitting or marking. The paper is placed on top of the light table and is aligned with this right angle marking. A transparent platen with marked scales is placed over the imaged paper and also aligned with the right angle fitting. The scales are placed over the corners of the image and image corner location readings are taken from the scales. These readings are then entered and fixed into a marking system such as an electrophotographic printer for reproduction of copies from the aligned and fixed original image.

  • Patent number: 7467838
    Abstract: An apparatus compensates for mechanical disturbances during a print process by adjusting the generation of image generating head actuation signals in anticipation of a mechanical disturbance. The apparatus includes a printer controller for generating signals to coordinate movement of components with a rotating image receiver in a printer and for generating data identifying a process disturbance arising from interaction of the rotating image receiver with the components and an expected time for the process disturbance, a process disturbance compensator for generating a process disturbance compensation signal that corresponds to the process disturbance identification and timing data, and an image generating head controller for adjusting an image generating head actuation signal with the process disturbance compensation signal.
