  • Patent number: 10509138
    Abstract: A system and method for accurately detecting contact between two objects in a medium comprises at least one sensor for detecting vibration of a first of the two objects and a central processing unit (CPU) for receiving an output of the at least one sensor, wherein the CPU performs the steps: converting the output of the sensor into digital form; during a calibration phase, changing the data from time domain to frequency domain; and during the calibration phase, determining a first frequency range associated with actual contact between the two objects, and a second frequency range associated with a false positive contact between the two objects. A signal processor is provided for filtering all data except that which falls within the first frequency range so as to confirm actual contact between the objects.

  • Patent number: 9251565
    Abstract: Methods and a computer program product for deriving a super-resolution image of a physical object by fusing cameras of multiple resolutions (spatial, temporal, or spectral), the super-resolution image characterized by a resolution exceeding a “camera imaging resolution” associated with each of a sequence of lower-resolution images of the physical object. The sequence of images of the physical object is obtained at a plurality of relative displacements with respect to the object by a hybrid camera system comprising at least two imaging systems. The imaging systems are characterized by respective temporal and spatial resolution and by spectral sensitivity, and may be distinct from one another in one or more of the foregoing dimensions. The imaging systems are either fixed, or subject to know motion, relative to each other. Image sequences derived by each imaging system are coregistered and deconvolved to solve for a resultant sequence of images.

  • Patent number: 8818079
    Abstract: Methods and a computer program product for deriving temperature information with respect to surfaces within a scene that is imaged radiometrically. A time sequence of radiometric data is acquired in frames viewed from distinct angles. A three-dimensional structure of the scene is derived, allowing viewing angles and distances to the imaged surfaces to be inferred. Normalized surface areas of the imaged surfaces are calculated based on the inferred viewing angles and emissivities of the imaged surfaces are corrected accordingly. Corrections also account for background radiation impinging on the imaged surfaces. The radiometric data are converted to a perceptible temperature map of the imaged surfaces.

  • Patent number: 8750647
    Abstract: Methods and a computer program product for deriving a super-resolution image of a physical object, the super-resolution image characterized by a resolution exceeding a “camera imaging resolution” associated with each of a sequence of lower-resolution images of the physical object. The sequence of images of the physical object is obtained at a plurality of relative displacements with respect to the object. An offset is passively associated with each of the plurality of images to derive effective camera movement, allowing for calculation of a kinetic point spread function on the basis of the effective camera movement. The image sequence is deconvolved, using the kinetic point spread function, to solve for a high-resolution image. Various applications such as portable cameras and infrared imaging for energy conservation are described.

  • Patent number: 8628714
    Abstract: A system and method for providing the capability of peeling thin polymer films from a substrate is provided. Generally, the method contains the steps of: providing a substrate having a top surface and a bottom surface; placing a peel initiator on the top surface; applying a polymer on the top surface of the substrate and a top surface of the peel initiator; curing the polymer, resulting in a thin-polymer film; and peeling the peel initiator from the substrate, thereby removing the thin-polymer film from the top surface of the substrate.

  • Publication number: 20110022567
    Abstract: A system for routing data in an automatic identification system includes an event management system (EMS), a real-time in-memory data structure (RIED) coupled to the EMS, the RIED for storing event information gathered by the EMS and a task management system (TMS) for ensuring that the RIED is updated by one transaction at a time. With this particular arrangement, a system for managing a large number of real-time events is provided. In one embodiment, the control system can be provided in a distributed hierarchical arrangement. The EMS of each control system can include filters which limit the amount of information provided to the next level in the hierarchy. In this manner the hierarchical control system network acts as a high volume data collector and processor. In some embodiments a level of the hierarchy can be removed spatially and/or temporally from an adjacent level in the hierarchy. This approach results in an intelligent network and also lends itself to scalability.

  • Patent number: 7765253
    Abstract: An object name system (ONS) for locating one or more servers associated with an Electronic Product Code (EPC) is described. The system utilizes translation format strings to translate an EPC to an EPC domain prefix. The ONS server matches the EPC number to the address of a second server which has extensive information about the product. The second server recognizes the incoming EPC's as belonging to a particular object or service.
