Abstract: Fluid line apparatus comprising a container, a line, a line end valve, pressurization means and control means, in which the line connects the container to the line end valve, in which a first function of the pressurization means is to pressurize the container such that fluid in the container is forced in the direction of the line end valve, in which a second function of the pressurization means is to pressurize the line such that fluid in the line is forced in the direction of the container, in which in use the control means controls the application of the pressurization means to the container and the line such that when fluid is to be dispensed from the apparatus it is forced towards the line end valve, and when the line is to be cleared of fluid, said fluid is forced towards the container, and in which fluid returning to the container is subjected to a filtering means.

Abstract: A method for rebuilding network agent messages. The method includes the steps of receiving partial network agent message, rebuilding the message and sending it to a network agent. The network message could be a protocol data unit under the simple network management protocol. The invention allows the network to function fully even when network interfaces do not pass complete network agent messages.

Abstract: A method for controlling messages in a software system. The method activates a report-handling module when a subroutine has a message to send. The subroutine passes an identification to the report-handling module. The subroutine then passes a message and message level to the report handling module. The report-handling module then determines the message level to be reported for that subroutine, the process from which that subroutine is sending messages and the message level to be reported for that process. If the message level of the message compares correctly to the message level of the subroutine and the process, the message is reported.

Abstract: A system and method are provided for controlling an embedded device. The method comprises: establishing a control code repository; establishing a plurality of objects corresponding to a plurality of control routines; establishing a range of selectable data values associated with each data object; accessing the repository through a plurality of mediums selected from the group including an embedded device front panel, simple network management protocol (SNMP), hypertext transport protocol (HTTP), a serial port, and a parallel port; and, using the control codes to communicate with an embedded device as follows: selecting data values; and, issuing commands to the embedded device in response to the data values.
