Abstract: A joist assembly system that is structured for dynamic retrieval of components, dynamic and precise positioning and location of retrieved components, assembly of the components to form a joist, and delivery of the assembled joist. The joist assembly system has a plurality of material handling systems, a plurality of welding systems, and a rigging table system. The material handling systems are structured to load and position the components such as chords and webs onto the rigging table. The rigging table in turn supports the chords or webs. Subsequently, the plurality of welding systems weld the webs to the chords to form the joist.

Abstract: Methods, systems, and apparatuses, including computer programs encoded on computer-readable media, for receiving a first communication request, from a web browser of a user. A request for information is sent to the web browser. A first communication as part of the first conversation is received from the user. A conversation identifier is identified and used to store the conversation of the first user. A request is received from a second, different, responder for the conversation. The conversation identifier is determined based on the request from the second responder. The request for information and first communication are retrieved from a persistent data store and sent to the second responder.

Abstract: Methods, systems, and apparatuses, including computer programs encoded on computer-readable media, for receiving a first communication request, from a web browser of a user. A first responder requests information and a response to the request for information is received as part of a conversation. A conversation identifier is used to store the conversation. Based on the conversation, the conversation is determined to stop and a second responder is identified. The conversation is then transferred to the second responder.

Abstract: Methods, systems, and apparatuses, including computer programs encoded on computer-readable media, for secure document management including receiving, at a kernel level of an operating system, a document access instruction for a document from a user level application. A document identifier associated with the document is retrieved. Document access permissions associated with the document identifier are determined. Whether the document access instruction for the document is allowable is determined based on the document access permissions. The document access instruction is allowed to proceed if the document access instruction is allowable. The document access instruction is denied if the document access instruction is not allowable.

Abstract: Methods, systems, and apparatuses, including computer programs encoded on computer-readable media, for receiving a first communication request, from a web browser of a first user. A request for information is sent, using a first active communication protocol, to the web browser. A first communication as part of the first conversation is received from the first user. A responder sends a communication to the first user. A first conversation identifier is identified and used to store the conversation of the first user. The responder sends a communication to a second user. A second active communication protocol is determined and used to send the communication. A second conversation identifier is identified and used to store the conversation of the second user.

Abstract: Methods, systems, and apparatuses, including computer programs encoded on computer-readable media, for receiving a first communication as part of a conversation, from an unauthenticated user of a web browser. A conversation identifier is determined based on the first communication. A first responder, a communication protocol, and a communication address of the first responder is determined. The first communication is sent to the first responder and a first reply is received. The conversation identifier is determined based on the first reply and the first reply is mapped to the web browser. The first reply is sent to the web browser.

Abstract: Methods, systems, and apparatuses, including computer programs encoded on computer-readable media, for receiving from responders conversation selection criteria and mode of communication information. A request for a conversation is received, from an initiator using a first communication mode that identifies a topic, but does not identify any responders. A conversation identifier is created. Possible responders are determined based on the topic and the conversation selection criteria. The topic of the conversation is sent to the possible responders, without identifying the initiator. A first response from a first responder is received using a second communication mode that is different than the first communication mode. The first response is mapped to the conversation based in part on the conversation identifier. The response is sent to the initiator using the first communication mode.
