  • Publication number: 20220261567
    Abstract: In some arrangements, product packaging is digitally watermarked over most of its extent to facilitate high-throughput item identification at retail checkouts. Imagery captured by conventional or plenoptic cameras can be processed (e.g., by GPUs) to derive several different perspective-transformed views—further minimizing the need to manually reposition items for identification. Crinkles and other deformations in product packaging can be optically sensed, allowing such surfaces to be virtually flattened to aid identification. Piles of items can be 3D-modelled and virtually segmented into geometric primitives to aid identification, and to discover locations of obscured items. Other data (e.g., including data from sensors in aisles, shelves and carts, and gaze tracking for clues about visual saliency) can be used in assessing identification hypotheses about an item. Logos may be identified and used—or ignored—in product identification. A great variety of other features and arrangements are also detailed.

  • Patent number: 10086186
    Abstract: An implantable multi-lumen access port including indicators for ascertaining characteristics of the port is disclosed. In one embodiment, the access port comprises a housing that defines a first reservoir and a second reservoir. A first septum and second septum are respectively coupled with the housing to provide selective access to the first and second reservoirs. Each septum includes a plurality of protrusions defined about a periphery thereof that are palpable after implantation of the port in a patient to determine a relative position of the first septum with respect to the second septum. A radiographically observable indicator is also included on a base of the housing, so as to provide information relating to a characteristic of the dual-lumen port, such as suitability for power injection of fluids. The indicator in one embodiment includes a substantially rigid radiopaque component.

  • Patent number: 10052471
    Abstract: An access port for providing subcutaneous access to a patient is disclosed. The access port includes a septum including palpable identification indicia thereon. In particular, the access port in one embodiment includes a body that defines a fluid cavity and a needle-penetrable septum covering the fluid cavity for providing access thereto. The septum defines an outer periphery. One or more palpation features are included on the septum. The palpation features each include a portion that extends in a radial direction beyond the outer periphery of the septum. The palpation features are therefore disposed relatively farther away from each other, simplifying palpation and identification thereof after the port has been subcutaneously implanted into a patient. The palpation features can be indicative of an attribute of the port, such as its ability to withstand fluid pressures and flow rates associated with power injection, for instance.

  • Patent number: 10016585
    Abstract: A power-injectable access port suitable for providing subcutaneous access to a patient and suitable for power injection. The access port includes a septum, a housing, and a reservoir defined by the septum and the housing. The septum may include a material that seals passages formed by puncturing the septum with a hollow slender element or another suitable access mechanism, and a radiopaque material forming a selected pattern when an x-ray is taken through the septum for identifying the power-injectable access port as being suitable for power injection. The housing and the septum may be structured for accommodating a pressure developed within the reservoir of at least 35 psi. The power-injectable access port may be designed to accommodate a flow rate of at least 1 milliliter per second of a fluid.

  • Patent number: 9937337
    Abstract: A power-injectable access port suitable for injecting contrast media therethrough at a rate of at least 1 milliliter per second. The access port includes a housing, a septum, a reservoir, and an outlet stem in fluid communication with the reservoir. The power-injectable access port is structured for accommodating a pressure developed within the reservoir of at least 35 psi. The septum may include a radiopaque material forming a selected pattern when an x-ray is taken through the septum. The pattern may identify the access port as capable of accommodating injection of contrast media at a rate of at least 1 milliliter per second and/or as capable of accommodating a pressure developed within the reservoir of at least 35 psi. The pattern may identify the location of the septum following implantation of the power-injectable access port.
