Disclosed are systems and methods which provide communications to a subscriber level of a network using a hybrid communication network. Preferred embodiments of a hybrid communication network of the present invention provide communications using both fiber media and electrically conductive media. Preferred embodiments of the present invention bring fiber optic cables to a point just beyond the last transformer before a subscriber in the power grid. At a point on the subscriber side of the last transformer, e.g., a low voltage subscriber distribution point transformer, the communication signal is preferably coupled from the fiber optic cable of the preferred embodiment to the power transmission line.

An apparatus and a system is provided that may be utilized to determine oil migration and oil displacement from a pre-oiled air filter. The present invention may also be utilized to determine if oil is displaced from the air filter onto a portion of the apparatus for visualization to a user. The present invention utilizes a demonstration apparatus having a system for forcing air through the oil subjected air filter thereby attempting to force displacement of the oil from the air filter. The apparatus utilizes a blowing means whereby the oil infused air filter is subject to higher than normal air flow and whereby the apparatus has a deflection portion whereby if oil is displaced from the air filter, it is deflected onto the deflection portion where it would be physically viewable to an observer present in the vicinity of the apparatus.

A device and method for increasing the rate of the firing cycle of a semi-automatic firearm includes a base that is adapted to support any one of a variety of semi-automatic firearms. The base includes a trigger extension with a grip, a slide mount, and a slide housed within the slide mount. At least the receiver, barrel, and trigger assembly of the firearm are secured to the base so that they may move as a single unit upon the base between a rearward position upon discharge of the firearm and a forward position. A biasing means continuously biases the receiver, barrel, and trigger assembly upon the base toward the forward position to effect successive discharges of the firearm.

A fixture for establishing stop surfaces against which a workpiece can be held to accurately locate it during robotic machine tool operations. The fixture includes a table surface having frusto-conical openings arranged in a preselected pattern to receive locator pins. Each locator pin has a frusto-conical base which automatically centers itself in the opening so that a robotic machine can insert the pins without having to first precisely align them with the openings. Each locator pin is locked in its opening by a releaseable slide mechanism which acts against the pin on opposite sides by wedging action to securely hold the pin down on the table.

An apparatus and a system is provided that may be utilized to determine air flow through an air filter and/or a plurality of air filters. The present invention utilizes a demonstration apparatus to illustrate the differences in air flow and air restriction between a plurality of different air filters and filtration media. The apparatus and system utilizes a common plenum which subjects the plurality of air filters to the same differential pressure. The air flows through a first side of the air filter and is measured on the second side of the air filter by utilizing a wind meter or similar device to gauge the amount of air flow velocity of the second side of the filter. Additionally, the apparatus and system utilizes a display means to illustrate the differing air velocity through the second side of the air filter.

A combination structure node is provided by a graphical programming development environment for use in a graphical program, where the combination structure node is operable to perform two or more control flow functions. For example, the combination structure node may be operable to perform two or more of: iteration, looping, conditional branching, sequencing, timed execution, event-driven execution, or other control flow functions. A user may include the combination structure node in a graphical program and associate a graphical code portion with the combination structure node. During execution of the graphical program, the combination structure node is operable to cause the associated graphical code portion to execute according to the two or more control flow functions performed by the combination structure node.
