Abstract: Systems, kits, and methods for establishing vascular access are described. A system typically includes a radially expandable sleeve, a dilator, and a guidewire. The methods comprise positioning the guidewire through an initial tissue tract, passing the radially expandable sleeve over the guidewire through the tissue tract to a target blood vessel, and thereafter passing the dilator over the guidewire and through the radially expandable sleeve to effect radial expansion of the sleeve. Use of the sleeve reduces the risk of injuring tissue surrounding the tissue tract by lessening the axial forces imparted to the tissue. Kits comprise at least the radially expandable sleeve together with instructions for use.

Abstract: A process variable transmitter that preferably includes a transmitter output circuit that provides bidirectional HART and controller area network communication transceiver lines. The transmitter output circuit also includes sensor circuit interface contacts. An isolated circuit couples to the sensor circuit interface contacts. The isolated circuit includes sensor circuitry sensing a process variable. The isolated circuit further comprises a galvanic isolation barrier galvanically isolating the sensor circuitry from the HART and controller area network transceiver lines. A stacked power supply provides power management. Other aspects may include a controller area network current limiter diagnostic output, timed sequencing of microcontroller startup and shutdown, a local operator interface and power management.

Abstract: The vehicle has a door movably mounted adjacent an occupant's seat and a pull strap by which the occupant may pull the door closed. A lamp is mounted on the door at a position generally outboard and concealed behind the pull strap. The pull strap is vertically located in relation to the occupant and the lap in a position so that light emanating from the lamp is directed onto the occupant lamp for reading when the door is closed and, simultaneously, shielded from shining into the occupant's eyes by the pull strap. When the door is swung open, the light shines down on the roadway.
