Abstract: A jobsite computer network has a local server connectable to a remote server via the internet, a network access transceiver connected to the local server, and a wireless device in wireless communication with the network access transceiver. The network access transceiver receives a message from the wireless device and sends a message to the local server. The local server utilizes information from the message to determine the location of the wireless device. The network access transceiver and/or the wireless device generate data which is sent to the remote server.

Abstract: In a preferred embodiment, an extendable tape measure made of polypropylene plastic has upper and lower elongated tapes having elongated sides integrally permanently connected by upright integral permanent flanges forming a squared tube of which the upper surface of the upper tape has length-indicating indicia arranged along the longitudinal axis thereof. The flanges are uprightly rigid lending support against downward bending of extended portions of the tape measure but sufficiently resilient as to be bendable at squared corners of junction with the upper and lower tapes when subjected to reforming pressure by a retraction first port in a forward face of a retraction-storage casing, to flatten the squared tubular shape to a flattened windable state during retraction. An upper inner end of one flange is enalrged and forms a first slot between that upper inner end relative to and in juxtaposition to the upper elongated tape.
