Abstract: Systems, devices, and methods relate to utilizing an electronic caliper to analyze an electronic electrocardiogram (ECG). An example method for includes outputting, by a display, an electronic ECG within a graphical user interface (GUI). An electronic caliper is output, by the display, as overlaid on the electronic ECG within the GUI. The electronic caliper includes a first electronic tip and a second electronic tip. The method further includes receiving, by a user input device, a user input signal and moving, based on the user input signal, the first electronic tip, the second electronic tip, or both the first electronic tip and the second electronic tip, relative to the electronic ECG within the GUI.

Abstract: A post installation templating assembly for positioning fence posts for setting includes a bar and a pair of brackets. Each bracket is coupled to and extends perpendicularly from a respective opposing end of the bar. Each bracket is configured to selectively couple to a respective post to parallelly position a pair of posts perpendicularly to the bar. The bar is configured to fixedly separate the pair of posts so that the pair of posts can be set with a separation equivalent to a distance between the pair of brackets.
