Abstract: A method for remote identification of security threats in an imaged object including transmitting an initialization signal to a first threat detection scanner over a communication network, the first threat detection scanner being located at a separate physical location, receiving a ready-to-send signal from the first threat detection scanner, the ready-to-send signal including a storage location of a scan image generated by the first threat detection scanner for security inspection, receiving the scan image from the first threat detection scanner, transmitting, after receiving the scan image from the first threat detection scanner, a second initialization signal to a second threat detection scanner at the separate physical location, generating a threat detection report based on a rendering of the scan image, and transmitting the threat detection report to the first threat detection scanner.

Abstract: A distance-measuring system includes a light source for transmitting a beam of light to a target, thereby generating a received beam. A calibration unit periodically calibrates the system by positioning a calibration target between the light source and the target so that the transmitted beam is interrupted, thereby generating a received calibration beam. The calibration unit also generates a calibration signal which is indicative of when the calibration target is generating the received calibration beam. A target sensor receives the reflected target and calibration beams and provides a target signal indicative of the reflected target and calibration beams. A reference sensor receives light from the light source and provides a reference signal to the processing circuitry. Processing circuitry receives the calibration, target, and reference signals and calculates the distance to the target based upon the target and reference signals and/or calibrates the system based upon the calibration signal.

Abstract: An automated top head cover and stem guide assembly adapted for covering a top opening in vertical vessels such as coking drums, and a method for remotely operating the assembly. The top head assembly includes a flanged connector unit attached pressure-tightly to a top flange opening of a coking drum and a top cover device including a cover unit pivotally attached to the flanged connector unit, so that the cover unit can be pivotally lifted and moved aside. A stem guide device is also pivotally attached to the top flange unit, so that a stem guide unit can be pivotally moved downwardly into place over the top flange unit opening, after a stem member is inserted into the vessel. Following coke removal from the drum, the stem member is withdrawn, the stem guide unit is pivotally moved upwardly, and the head cover unit is moved downwardly to cover the coking drum flanged unit. The invention also discloses method steps for operating the head cover and stem guide devices of the assembly.
