Abstract: A closure includes a door configured for movement with respect to an opening between a closed position and an open position, and a movable roof panel that configured for connection to the body for movement with respect to the opening between a closed position and an open position by pivoting relative to the body. The closure also includes an access structure that is configured to be movable from a stowed position to a deployed position when the door is in the open position, wherein the access structure defines a walking surface in the deployed position.

Abstract: Systems and methods for a network diagnostic device or component that is placed in-line between two nodes in a network to capture the value of a component of a speed negotiation signal. The network diagnostic component receives a speed negotiation signal from a first node for communication with a second node. The speed negotiation signal may be received by a receive module. The speed negotiation signal includes one at least a first portion that comprises one or more data units. The network diagnostic component measures the duration of the data units of the first component of the speed negotiation data. This measurement may be performed by a measurement module. The network diagnostic component compares the measured duration with a desired duration. The comparison may be performed by a measurement module. A record of whether the measured duration compares with the desired duration is then generated by a generation module.

Abstract: A network diagnostic component that is placed in-line between a first and second node. The diagnostic component is used to perform a comparison operation on any specified portion of a network data frame. For example, the first node may communicate with the second node using a network data frame that includes one or more data units. The network diagnostic component uses a starting and ending address that specify where in the network data frame to begin and end the comparison operation. A match template that specifies a particular condition for comparison is also used. The network diagnostic component then performs the comparison operation by searching for a data unit that at least partially matches the comparison condition in the portion of the network data frame specified by the starting and ending addresses. The data unit may be located at any location in the specified portion of the data frame.

Abstract: Embodiments disclose a method and computer program products for automatically generating a list of search criteria to be used by the computing system when searching captured data frames for one or more resulting data frames having a specific protocol field. The method includes an act of accessing a specific protocol field from one of the captured data frames and an act of accessing protocol definitions. The captured data frame is then interpreted using the protocol definitions to generate a list of additional protocol field and value pairs to use for searching the captured data frames. Finally, the specific protocol field and the list of additional protocol field and value pairs are used to automatically identify the one or more resulting data frames having the specific protocol field.

Abstract: A system and method of triggering data capture in a high-speed communications network is disclosed. The triggering system enables the capture of desired data from the network according to triggers related to high-level statistical and transactional elements of the data. The triggering system includes a statistics engine that analyzes network data at the line speed of the high-speed network, thereby enabling the present system to trigger on data transmitted via networks with line speeds exceeding 1 Gbit per second. The present system preferably comprises a portion of a protocol analyzer or similar device in order to detect and diagnose problem conditions existing in or relating to the network data.
