Abstract: A cardiovascular graft is provided with highly reduced thrombogenicity. The cardiovascular graft is an electrospun non-woven mesh produced from supramolecular polymers with large diameter fibers. The cardiovascular graft can be implemented as a vascular graft into the human body to allow vascular bypass/reconstruction, or repeated venous access for dialysis treatment, as well as other disorders of small-diameter blood vessels.

Abstract: A method, computer system, and a computer program product for event-related item tracking are provided. A first computer receives from an event database associated with personal information management software a reminder of an upcoming event for a first user. The first computer retrieves an electronic list of items needed by the first user for the upcoming event. The first computer retrieves, from a location database, location information of a first item from the electronic list of items. The location database was generated using image information of the first item. The first computer transmits the electronic list of items and the location information of the first item for presentation to the first user.

Abstract: A multi-port connector includes a housing with a proximal portion defining outer surfaces of a male-type multi-port connection configured to fit within a female-type multi-port connection. The multi-port connector further comprises pin conductors for electrically connecting to the female-type connection, a prong configured to lock with the female-type connection, and a button configured, when pressed, to displace the prong for unlocking. The button is located on a longer side of the housing. A multi-port connector also includes a mount at the distal end of each pin conductor, and cable seatings with a through opening along a longitudinal direction thereof. Each cable seating is configured to be inserted within the mount of a corresponding pin conductor by an insertion depth. A proximal first end portion of each cable seating is longer than the insertion depth in the longitudinal direction, and a distal second end portion of each cable seating includes metal.

Abstract: A printing device includes: an inkjet printhead having a row of ink ejection devices; a lift mechanism configured for raising and lowering the printhead between a maintenance position and a printing position; a conveyor tape positioned below the printhead in the printing position, the conveyor tape defining a slot aligned with the row of ink ejection devices; and a tape movement mechanism for moving the tape longitudinally along the length of the printhead. The tape movement mechanism is configured to move the tape along the printhead during printing, thereby conveying condensate accumulated on an underside of the tape away from the printhead.

Abstract: The following relates generally to user selection of parameters to approximate desired properties of light scattering. More specifically, in some embodiments, a graphical user interface (GUI) is provided. In some embodiments, in a forward configuration, the GUI accepts an input parameter that is a physical property or optical property of a nanoparticle material (e.g., nanoparticle size, shape, etc.), and outputs an optical effect of the nanoparticle material (e.g., a color, a graph of a reflectance fraction vs. wavelength, etc.); whereas, in an inverse configuration, the GUI accepts the optical effect as the input, and outputs a physical property or optical property of the nanoparticle material.

Abstract: A printing device includes: an inkjet printhead; a lift mechanism for raising and lowering the printhead through a lift path; and a pivotally movable spit flap positioned in the lift path. The spit flap is configured to swing away from the lift path when the printhead contacts the spit flap during lowering of the printhead.

In at least one embodiment, a closed-cell metal oxide particle comprises a metal oxide matrix defining an array of closed-cells. Each closed-cell encapsulates a media-inaccessible void volume. The outer surface of the closed-cell metal oxide particle is defined by the array of closed-cells.

Abstract: A method of installing a printhead in a print module includes the steps of: positioning the printhead in a nest of the print module; moving first and second ink couplings towards the nest and into engagement with complementary first and second ink ports positioned at opposite ends of the printhead; and moving a depressor towards the nest and into urging engagement with a portion of the printhead positioned between the first and second ink ports. The first ink coupling, the second ink coupling and the depressor are moved simultaneously, linearly and parallel to each other, thereby to datum the printhead against the nest.

Abstract: This matrix-like power/communications system is a decentralized array of scalable self-configuring modular electrical components that are easily physically and electrically replaceable and combinable into any series, parallel or bypassed state with any power supply and bi-directional data communications input; resulting in an autonomous system survivable in the harshest environments including physical shock, vibration, vacuum, radiation, thermal, and electromagnetic interference; and provides a communication interface for external control or monitoring, simultaneously being capable of reconfiguring itself if an internal battery cell failure occurs by switching in a spare cell(s) to replace a dead cell within the system for maintaining uninterrupted power and communications during the upset event, while being capable of reconfiguring itself autonomously into an arrangement of series/parallel states for charge/discharge while enabling cell balancing and continual monitoring of all individual cell parameters, an

Abstract: A phase Doppler radar system may comprise a pulse Doppler receiver/transmitter (R/T) subsystem coupled with a processing subsystem. The system may determine target velocity and target detection events by collecting pulses from the pulse Doppler R/T subsystem, determine an undifferentiated phase of each of the pulses, differentiate the pulses, and determine a differentiated phase of each of the pulses. The system may perform a linear fit of the differentiated phases of the pulses to produce a slope and an intercept. The system may determine a set of initial estimates of coefficients of a nonlinear fit equation. The system may perform iterations of a nonlinear least squares fit, beginning with the initial coefficient estimates, to produce a non-linear fit result. The system may determine a goodness-of-fit (GoF) statistic associated with the nonlinear fit result, and declare a detection event when the GoF is superior to a GoF statistic associated Gaussian noise.
