摘要:
A needleless luer access connector is disclosed having a septum disposed in a housing. The septum has a proximal portion with a cross section, a medial portion with a cross section smaller than the cross section of the proximal portion, and a distal portion. A longitudinal slit extends through the septum from the proximal portion to the distal portion. The septum and housing are designed so that septum will not be rotated or removed from the housing when the connector is accessed by a male luer taper. In addition, the septum and housing are designed to bias the slit at the distal portion closed and so a male luer connector does not have to extend completely through the distal portion to open the slit at the distal portion. Finally, the septum and housing are designed to minimize the amount of dead space in the connector when accessed with a male luer taper.

A process control routine may include a first internal function block for executing a control operation based on an input signal and an information conduit communicatively connected to the first internal function block. The information conduit may have an output adapted to provide the input signal to the first internal function block. The process control routine may further include an external function block communicatively connected to the information conduit and adapted to generate the input signal such that the output signal is directly provided to the information conduit prior to the execution of the control operation.

A medical device may include an extravascular system for communication of fluid with a vascular system, a fluid path within the extravascular system, and a fluid flow director in communication with the fluid path. The director encourages movement of stagnant fluid within the fluid path of the extravascular system. A method may include providing an extravascular system having a fluid path and encouraging the movement of stagnant fluid within the fluid path of the extravascular system.

An editing device accesses a media program and a user of the editing device designates points of interest within the media program. Bookmarks are generated for the designated points of interest. The bookmarks are transmitted via a network from the editing device to a playback device. During presentation of the media program, the playback device uses the bookmarks to skip to one position of interest to another, as defined by the bookmarks, in response to user commands.

Techniques are described for reducing splice loss between a pair of optical fibers. A first fiber is spliced to a second fiber at a splice point. A region of the spliced fibers, including the splice point, is thermally treated to cause a controlled diffusion of dopants in the region. A controlled tension is then applied to the splice region while heating it to a predetermined temperature to produce a controlled change in the splice region's strain state. Further described is a heat and tension station for performing a heat and tension technique on a pair of spliced fibers.

A portable dog-training transmitter unit for controlling remote collar-mounted receiver/stimulus units includes first, second, and third switches for causing corresponding transmitted stimulus control signals to be recognized by corresponding first, second, or third receiver/stimulus units. A multiple-position switch sets the use of transmitted codes that control the amplitudes of stimulus signals produced by the recognizing receiver/stimulus unit. The transmitter unit is supported in a holster that is pivotally supported by a belt clip through the use of a pivot pin that is pivotally retained in a receiving slot of the belt clip. The transmitter unit includes a controller which polls the states of the various switches to produce a digital signal that is shaped by a buffer circuit, FM modulated, preamplified, and coupled by a simplified matching network to the input of a power amplifier. A single pi matching network is coupled to match an output of the power amplifier to an antenna of the transmitter unit.

A digital control system automatically senses when a new controller is attached to a network and determines the number and types of I/O Ports that are attached to the new controller. The digital control system formats and displays the I/O Port information upon request by a user. The digital control system program also includes an automatic configuration program that responds to sensing of a new controller by automatically configuring the input/output (I/O) subsystem. The user adds a new controller without setting any physical switches or nodes. A user optionally supplies configuration information for a device into a database, prior to connection of a device. Upon connection of the device, the device is automatically sensed and configured using the database configuration information, without setting of physical switches or node address information on the devices.

A direct harvester includes a cutting portion, a lifting portion and a feeding portion. The cutting portion typically includes a cutter rod for severing plant roots and a kicker rod for encouraging the plant to the soil surface. The lifting portion typically includes a rotating pickup head for lifting the plants off the soil and separating the plant from the soil, and a pair of rotating tubes to move the plants and encourage further separation of soil from the plants. The feeding portion includes an auger which receives the plants from the rotating tubes and channels the plants into the opening of a combine feeder housing. Preferably, the floor below the auger is screened to allow soil which is knocked free by the auger to fall back to the ground. Additionally the lifting portion and the feeding portion are preferably pivotably attached to one another to enable the harvester to adapt to differing contours in the soil.
