Abstract: Described are systems and methods for natively generating a first protocol, including receiving, via a user device, a first transmission and first transmission data, wherein the first transmission is at least one of a call, a voicemail, a text message, an audio message, or a video message, determining, via a first trained machine learning model, the first protocol based on the first transmission and the first transmission data, the first trained machine learning model having been trained to determine one or more protocols using training transmissions and training transmission data, generating, via the first trained machine learning model, a first responsive output based on the first protocol, and transmitting, via the user device, the first responsive output to a third-party device.

Abstract: The invention provides a flexible guide tube with prongs or other work-engaging means at one end. These prongs may be stabbed into an obstruction in a hollow wall to set the position of a throughhole and to hold the tubular guide in a fixed position against the torsional, or other, forces of a drill or other cutting tool used to cut the hole. The drill may be rotated by means of a flexible shaft running within the guide tube. After a throughhole is cut in the obstruction, a line-fishing member may be inserted through the guide tube and the obstruction and into a space on the distal side of the obstruction. The line-fishing apparatus may comprise an end portion having a collapsed state in which it can pass through the guide tube and an expanded state in which it provides a visible target that can be readily engaged by tools operated by a worker on the distal side of the obstruction who is prohibited from getting any closer than a few yards from the target.
