  • Patent number: 11953468
    Abstract: According to various, but not necessarily all, embodiments there is provided an apparatus comprising means for: controlling one or more electroacoustic transducers of a device to create a standing wave having a displacement antinode at an expected location of a component of the device; receiving a signal representing sound generated by vibration of the component driven by the standing wave; causing analysis of the signal to determine whether there is a defect based on whether the signal represents a sound that would be expected to result from vibration of the component driven by the standing wave in the absence of a defect.

  • Patent number: 11034478
    Abstract: A double-walled container includes a top opening, and a bottom opening, opposite the top opening. A removable top cap engages with threads at the top opening and a removable bottom cap engages with threads at the bottom opening. The double-walled container includes an outer wall and an inner wall. A channel formed on and encircling the outer wall includes a vacuum port through which air between the outer and inner walls is drawn out to form an insulating space between the inner and outer walls. A band is positioned within the channel to cover the vacuum port.

  • Patent number: 6681043
    Abstract: A video processing environment includes a user interface and processing shell from which various video processing ‘plug-in’ programs are accessed. The shell insulates the plug-ins from the intricacies of reading various file formats. The user interface allows an operator to load a video sequence, define and view one or more video objects on any one or more frames of the video sequence, edit existing video object segmentations, view video objects across a series of video frames, and encode video objects among a video sequence in a desired format. Various encoding parameters can be adjusted allowing the operator to view the video sequence encoded at the various parameter settings. The user interface includes a video window, a time-line window, a zoom window, a set of menus including a menu of plug-in programs, and a set of dialogue boxes, including encoding parameter dialogue boxes.

  • Publication number: 20020114309
    Abstract: Embodiments of the present invention organize a collection of data frames which can be allocated to mobilestations into sets of contiguous groups of frames Each group of frames is mutually independent in time (i.e., each group of contiguous frames does not overlap, in time, with another group of contiguous frames). Each orthogonal group of frames is assigned to a BS (a single BS may be assigned more than one orthogonal group of frames). The BS may allocate its assigned orthogonal group of frames to a plurality of MSs thus forming a plurality of communications channels. In a further embodiment, a single BS, having been assigned more than one orthogonal group of frames, can assign each orthogonal group of frames to sectors (or sections) within a wireless cell.
