Abstract: A device (901) is manufactured from a sheet layer (100) defining a plurality of panels (101,102,103). Each panel is connected to at least one other panel along a common edge (104). A perforation (105) extends along the common edge and defines a separation location allowing the each panel to be separated from adjoining panels when an applied force pulls each panel away from the adjoining panels. A score line (115) bisects each panel and is oriented orthogonally with the perforation. The score line allows a first portion (116) of each panel to fold about the score line to abut a second portion (117) of each panel. An adhesive (501), disposed along the first portion, retains the first portion to the second portion, as well as retains the filament between the first portion and the second portion.

Abstract: A stethoscope (100) includes one or more earpieces (101,102), a sound receiving bell (104), and at least one acoustic conduit (103) coupling the one or more earpieces and the sound receiving bell. A photoluminsecent pigmented material (115) is applied to the at least one acoustic conduit to make it glow in the dark.
