  • Patent number: 8386957
    Abstract: In a method for dynamically scaling an original background layout having at least one element, an instruction to employ the original background layout in a new page that differs in at least one of size and aspect ratio from at least one of the size and aspect ratio of the original background layout is received. In addition, a type and a position of the at least one element is identified and one or more constraints are applied on at least one characteristic of the at least one element to modify the at least one characteristic of the at least one element for inclusion in the new page, in which the one or more constraints are based upon the type and position of the at least one element.

  • Publication number: 20130045751
    Abstract: Example methods, apparatuses, or articles of manufacture are disclosed herein that may be utilized, in whole or in part, to facilitate or support one or more operations or techniques for logo detection for indoor positioning for use in or with a mobile device. Briefly, in accordance with one implementation, a method may include extracting, at a mobile device, visual features from one or more images captured via a camera sensor of the mobile device; and estimating a location of the mobile device based, at least in part, on a match between extracted visual features and one or more brand-specific visual signatures associated with one or more points of interest of one or more known locations. In some instances, an estimated location of a mobile device may be refined based, at least in part, on at least one additional POI of one or more POIs of one or more known locations.

  • Publication number: 20120308087
    Abstract: A system and a method are provided for determining an estimated age of an individual of interest based on images in an image collection. An example system includes a memory for storing computer executable instructions, and a processing unit for accessing the memory and executing the computer executable instructions. The computer executable instructions include an age class estimator to classify a plurality of images of the individual into age classes, each age class corresponding to an interval of age, and each image having a known time stamp, a probability determination engine to determine, for each age class, a value of class probability that an image in the collection falls within the age class, an age determination engine to determine a transition time based on the values of class probability and the known time stamp, and to determine the estimated age of the individual based on the determined transition time.

  • Publication number: 20120264000
    Abstract: A hybrid battery module of the present invention includes a lithium iron battery pack and a lithium manganese battery pack. The lithium iron battery pack includes at least one lithium iron battery which is electrically connected in series, and the lithium iron battery has an anode and a cathode. The lithium manganese battery pack includes at least one lithium manganese battery which is electrically connected in series, and the lithium manganese battery has an anode and a cathode. The lithium iron battery pack and the lithium manganese battery pack are electrically connected in parallel to each other. Thereby, the hybrid battery module has high discharge efficiency, high electric capacity, a small volume and a light weight. Furthermore, the production cost of the present invention is lower than a complete lithium iron battery pack, and the hybrid battery module is much safer to be used than a complete lithium manganese battery pack.

  • Publication number: 20120231533
    Abstract: A chamber device for analyzing living cell(s). The chamber device includes a base and a lid that when reversibly pressed closed create a chamber. The base is configured with an optically transparent well to contain at least one cell. The lid has a breadth greater than the base and is configured to contain at least one sensor. The lid is further configured with a lip that when pressed between the lid and the base creates an impermeable seal. The base and the lid are configured so that, when closed and in use, the sensor remains spatially apart from the at least one cell.

  • Patent number: 8245131
    Abstract: Methods, systems and machine-readable instructions for constraining layout variations for accommodating variable content in electronic documents are described. In one aspect, explicit logical blocks extracted from the electronic document are received. Each of the explicit logical blocks corresponds to a content region of the electronic document assigned a respective content style. Layout relationships among the explicit logical blocks are determined. Based on the layout relationships, rules constraining layout variations among implicit logical blocks to approximate the electronic document in appearance while accommodating variable content are generated. Each of the implicit logical blocks corresponds to a respective one of the explicit logical blocks and accommodates variable content having the content style assigned to the corresponding explicit logical block. The rules are stored in a machine-readable medium.

  • Publication number: 20120147046
    Abstract: A regular mesh of rectangular cells (76) of uniform size is defined. The regular mesh is aligned with a non-rectangular layout boundary (18) such that a count of ones of the cells (76) having at least a prescribed fraction of their size contained within the layout boundary (18) is maximized. A layout (34) of frames (36) within the layout boundary (18) is determined based on the locations of the cells (76) with respect to the layout boundary (18), wherein the frames (36) define respective size dimensions and positions of respective views (47) of graphic objects (12) on a page (38). The views (47) of the graphic objects (12) arranged in accordance with the layout (34) of the frames (36) are outputted on the page (38).

  • Patent number: 8000529
    Abstract: Embodiments of the present invention recite a system and method for creating an editable template from a document image. In one embodiment of the present invention, the spatial characteristics and the color characteristics of at least one region of a document are identified. A set of characteristics of a graphic representation within the region are then determined without the necessity of recognizing a character comprising the graphic representation. An editable template is then created comprising a second region having the same spatial characteristics and the same color characteristics of the at least one region of the document and comprising a second graphic representation which is defined by the set of characteristics of the first graphic representation.
