Abstract: An electronic target measurement system is disclosed such that the system includes image capture device(s), an access point device, and a user device. Each image capture device acquires a series of successive real-time images of at least one target with a plurality of regions of interest (ROIs). The access point device receives the images and transmits the images to a user device. The user device performs image preprocessing on the images, determines via an image differentiation process that a difference exists between the images, extracts the ROIs and locations of impact (LOIs) from the received image, and determines ROI center points, LOIs within the ROIs, and LOI center points. The user device also determines regional scores based on the distances between the ROI center points the LOI center points, and then a total score by adding the regional scores for the plurality of extracted ROIs.

Abstract: An electric shielding apparatus comprises a main shielding enclosure structure and a generally concentric frame joined thereto. Cooperatively they form an electromagnetic radiation shield between an inside electric conductor and an outside space, and are furthermore arranged for mating to an external coaxial conductor viz á viz the concentric frame. In particular, the concentric frame is extrusion-formed from and constitutes a structurally unity with the main shielding enclosure.
