Abstract: An intermediate indicator assembly (10, 30) is provided 
which is adapted to define a time interval or critical 
temperature indicator (12, 48) when folded along a fold line 
(20, 34). The intermediate indicator assembly (10, 30) 
reduces the overall cost of the indicator (12, 48) by eliminat­
ing barrier strips or separating frames which were previously 
necessary to maintain an indicating wick (26, 42) separate 
from an indicating liquid (28, 38) which may be sorbed into 
the wick (26, 42) to provide a visual indication that a 
predetermined time interval has expired or that the device 
has been exposed to a predetermined temperature. Accord­
ing to the invention, the liquid (28, 38) and the wick (26, 42) 
are disposed on opposite sides of the fold line (20, 34) along 
which the intermediate indicator assembly (10, 30) may be 
subsequently folded to activate the indicator (12,  48) and 
place it into operation.

Abstract: The present invention relates to an outdoor 
courtesy bench (10) and is specifically concerned with 
providing such a bench (10) which is constructed of a light­
weight easily handled material for visibly displaying a 
plurality of advertising panels (74), both on the front and 
back of the bench. Prior art devices have been 
constructed of heavy, high maintenance materials which 
in use are subject to the accumulation of debris and 
the like therebeneath and which are subject to the 
collection of rain water and the like on the seat 
portion thereof and have only been adaptable to display 
a single advertising panel on the frontside thereof. 
The present invention overcomes these deficiencies by 
providing an outdoor courtesy bench (10) of three-piece 
modular construction of a lightweight material having a 
hollow base (11) portion to which discreet weight members (31) 
can be added for increased weight and stability of the 
bench after positioning at a selected bench site. The 
base (11) completely covers the ground area on which it is 
disposed thereby eliminating any space beneath the 
bench thus precluding the accumulation of any debris 
under the bench and provides a channeled upper seat 
portion which effectively disperses any rain water 
therefrom to prevent puddling or any accumulation of 
such water on the seat for fast drying and convenient 
use of the bench in all weather conditions.

Abstract: This printed circuit board (200) with optical 
signal distribution layer (101, 102) uses a layer of 
transparent material or an optical fiber mat build into the 
laminated printed circuit board structure to interconnect 
various opto-electrical devices (110,111) which are attached 
to the surface of the printed circuit board.  
     The optical devices are connected to the buried 
optical fiber layer by drilling vias in the printed circuit 
board to intercept the fiber or the particular optical 
signal distribution layer at a desired location. The via is 
then filled with an optical material (210) whose optical 
properties provide for the coupling of light energy from the 
intercepted optical signal distribution layer through the 
via material to the surface of the printed circuit board. 
Opto-electrical devices are connected over the top of these 
vias and perform the optical light energy to electrical 
signal conversion function.
