Impact print-type hot embossing technology uses an impact header to engrave dot patterns on flexible materials in real time. This technology has a control system for controlling the on-off motion and position of the impact header to create dot patterns with various widths and depths on different polymer films.

A device was created to demonstrate electromyography-based control to a lay audience. After the success of the initial device, a second device was made with greater flexibility in functionality for demonstration and research purposes. This protocol describes the process of building and calibrating both devices.
FAQs
Its main structural contribution is tying adjacent wythes into a more coherent assembly. Because the headers extend across or into the wall, forces can be transferred between the wall’s thickness rather than remaining associated with separate layers. This interconnection improves stability and supports more reliable load distribution, which is why the course matters in structural masonry detailing.
Compared with a course made only of stretchers, a header course provides a direct connection across the wall’s thickness. That connection helps adjacent wythes act as a more integrated assembly and reduces the dependence on separate layers for stability. The distinction is especially relevant when engineers evaluate bond patterns or select wall-building methods.
At corners and intersections, masonry changes direction or meets another wall segment, so continuity and tying become important. Header courses help connect the involved portions and support force transfer through these details. Their placement therefore affects how clearly the construction expresses a coherent structural assembly in drawings and finished masonry.
When reading construction drawings, engineers should identify where headers occur, how their orientation relates to the wall’s thickness, and whether the pattern provides the intended interconnection. This review links the graphical layout to expected force transfer, stability, and load distribution. It also helps distinguish a header course from a stretcher-only arrangement.
They are incorporated by placing header units within the planned sequence of masonry courses so the bond pattern connects the wall’s wythes where required. The important design task is not simply adding headers, but coordinating their locations with the overall wall layout, corners, and intersections. This coordination supports consistent construction and makes the intended structural relationship easier to interpret.
Header courses are relevant when the design needs reliable tying across the wall thickness, improved stability, or better force distribution between adjacent wythes. They are therefore considered in wall construction, bond-pattern selection, and detailing at corners or intersections, especially when drawings and performance assessments must reflect the wall’s structural assembly.
