Abstract: A method at an electronic device with a display includes: displaying a user interface having a first region and a second region; receiving, and displaying in the first region of the user interface, a live video stream of a physical environment captured by a remote video camera; displaying, in the second region, a timeline corresponding to a timespan for a first portion of a duration during which the live video stream may have been recorded; in response to receiving a user interaction to move the timespan to a second portion of the duration, transitioning the displayed timeline to a new timeline that corresponds to the timespan for the second portion, and while transitioning, displaying, in the first region, a subset of video frames representing the first and/or second portion of the duration.

Abstract: A radiation-reducing door assembly which may be configured as either an entry port or a ventilation port. The door assembly includes a split ring flange-type mounting bracket which can be quickly and easily installed on a manway flange regardless of the state of the manway cover mounting studs. A pair of radiation shielding doors or a ventilation port door may be quickly and easily coupled to the split ring mounting bracket.

Abstract: A probe positioner capable of being supported from a tube sheet of a nuclear steam generator for positioning a probe in relationship to the tube sheet of the nuclear steam generator comprises a locking mechanism for locking the probe positioner in the tube sheet and a plurality of rotatable arms for positioning the probe. The probe positioner also comprises quick disconnect motors for rotating the arms of the probe positioner relative to each other.

Abstract: An inspection probe for inspecting tubular members comprises a housing having a plurality of feeler wires extending therefrom and into contact with the inner side of the tubular members. The inspection probe also comprises a radiation source and radiation sensors arranged in the probe so that the sensors can detect radiation from the source that has been reflected from the feeler wires. The sensors are arranged so that when the feeler wires encounter an irregularity in the tubular member the amount radiation reflected from the feeler wires to the sensors will change in relation to the size of the irregularity. Output from the sensors is calibrated to remotely indicate the size and location of the irregularity.
