Abstract: A process equipment heating system has a group of electric heaters and a heater checking system. The heater checking system is configured to determine a resistance value R1 for the group of electric heaters, compare the resistance value R1 with a reference resistance value RR and judge a fault condition if the resistance value R1 differs from the reference resistance value RR by more than a predetermined amount.

Abstract: In embodiments, apparatuses, methods and storage media are described that are associated with synchronization of captured video using a frame-marking clock (“FMC”). An FMC may be configured to display images of time codes which advance at a regular rate. During capture of video by video capture devices, the FMC may be introduced into the captured video. The FMC may be configured to display time code images in a manner such that each image may be uniquely identified in the captured video. In various embodiments, the images may be displayed in different portions of a display such that two consecutive time codes are not displayed in the same portion to facilitate unique identification of each time code in the captured video. After video capture is complete, time codes may be subsequently used to establish a common time base and synchronize the instances of video.
