  • Patent number: 10517633
    Abstract: A device suitable for removing material from a living being is provided, featuring at least an aspiration pump, powered by a motor. The aspiration pump and any optional infusate pump preferably feature a helical pumping mechanism, and operate at a high rate of rotation, thereby ensuring adequate pumping performance and flexibility. The helical pumping mechanism may be a helical coiled wire about a central core tube. The helical coil wire, whether together with, or independent of, the core tube, may be rotated to cause a pumping action. Additionally, a narrow crossing profile is maintained, ensuring that the device may reach more tortuous regions of the vasculature. In one embodiment, the system comprises a wire-guided mono-rail catheter with a working head mounted on a flexible portion of the catheter that can laterally displace away from the guide wire to facilitate thrombus removal.

  • Patent number: 10509911
    Abstract: Methods and systems are provided for conditionally granting access to service levels based on a determined security state of the device requesting access. A software component, upon receiving a request for access to a provider having a plurality of service levels, determines the current security state of the requesting device. The software component compares that security state to a policy associated with the provider. The software component then allows the requesting device access to the provider services where the device's current security state meets or exceeds the security state required for the service.

  • Publication number: 20190339468
    Abstract: Consistent with the present disclosure, one or more spare Widely Tunable Lasers (WTLs) are integrated on a PIC. In the event that a channel, including, for example, a laser, a modulator and a semiconductor optical amplifier in a transmitter or Tx PIC, or a laser, optical hybrid, and photodiodes, for example, in a receiver PIC (Rx PIC), includes one or more defective devices, a spare channel is selected that includes a widely tunable laser (WTL) which may be tuned to the wavelength associated with any of the channels on the PIC. Accordingly, the spare channel replaces the defective channel or the lowest performing channel and outputs modulated optical signals at the wavelength associated with the defective channel. Thus, even though a defective channel may be present, a die consistent with the present disclosure may still output or receive the desired channels because the spare channel replaces the defective channel.

  • Publication number: 20190188435
    Abstract: A variety of technologies having practical application in retail stores are detailed. One is an improved method of identifying items selected by customers. This method includes receiving sensor data from plural sensors, including (a) ceiling-mounted cameras that monitor tracks of customers through aisles of the store, and (b) inventory sensors that are positioned to monitor removal of stock from store shelves. This received sensor data is employed in evaluating plural alternate item identification hypotheses. These hypotheses include a first hypothesis that a customer selected an item having a first identity, and a second hypothesis that the customer selected an item having a second identity. A confidence score is associated with each of the first and second item selection hypotheses. These confidence scores are refined as sensor data is received, e.g., increasing a confidence score of one hypothesis, and reducing a confidence score of another.

  • 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.
