  • Publication number: 20220361841
    Abstract: Systems, methods, and devices that perform flow scan sequences are provided. In one embodiment, an ultrasound imaging system includes an intraluminal catheter or guidewire, an annular array of acoustic elements positioned around a circumference of the catheter or guidewire, and a processor in communication with the annular array. The processor is configured to activate a first subaperture of the annular array at a first time, thereafter, activate a second interleaving subaperture, and activate the first subaperture again at a different, second time such that the scan sequence moves around the circumference of the catheter or guidewire. Temporal differences between the received ultrasound signals obtained by the first subaperture at the first and second times are determined to detect motion around the annular array. By interleaving subaperture firings, the total number of firings to form an image frame can be reduced.

  • Patent number: 11460173
    Abstract: Rack-type backlight light emitting element (LEE) printed circuit boards (PCBs) with at least two layers to provide redundant current paths. This enables a PCB strip to be broken at designated perforations in the field in order to accommodate pipes or fixtures that require formation of a gap in the rack array. The entire length and width of an array can be sized in the field. A plurality of PCB arrays can be serially chained together with the system. A chain of PCB strips is snapped into clips, which in turn snap into rails that are fastened to a surface. The mounting system includes various types of clips, such as end clips, clips for different LEE patterns on the PCBs, and mounting clips to secure the rails to a surface.

  • Publication number: 20220295436
    Abstract: Methods and systems provide synchronized sharing of multimedia between multiple devices. The multiple devices may form an ad-hoc network for sharing of multimedia. In an embodiment, group members may have playlist manipulation privileges such as pausing, rewinding, fast forwarding, or adding tracks to the playlist. A system may stream or distribute content according to the shared playlist. Playback may be synchronized for group members so that everyone is exposed to a same part of the content as the same time.

  • Patent number: 10859504
    Abstract: The present invention relates to methods of enhancing chemiluminescence from a chemiluminescent label comprising contacting a chemiluminescent label with an acid in the presence of a degradable cationic surfactant and hydrogen peroxide followed by the addition of a base. Related kits containing such degradable cationic surfactant are also provided. The degradable cationic surfactant can compress light emission time of the chemiluminescent label to an extent that is comparable to or shorter than conventional surfactants. The degradable cationic surfactant can also increase chemiluminescence of the chemiluminescent label, providing increased light emission output that is comparable to conventional surfactants.
