Patent CA-2297813-A1 (CA)
Title: Uniform light extraction from light guide, independently of light guide length
Inventor: WHITEHEAD LORNE A
IPC: G02B6/00
Filed: 1998-03-13
Abstract: A light guide light extraction mechanism can be formed in a predetermined maximum length to yield a predetermined light emission characteristic. Any shorter length segment removed from a predetermined end of the extraction mechanism and installed in a light guide of that shorter length causes the shorter length light guide to exhibit substantially uniform surface brightness. This obviates the need for cumbersome trial and error development of a different light extraction mechanism for each such shorter light guide.

Patent CA-2302420-A1 (CA)
Inventor: EAKIN THOMAS GEORGE
IPC: A61L15/56
Filed: 1998-09-01
Abstract: A wound dressing is formed from a covering release layer, a dressing layer, an indicator layer, a transparent or translucent indicator bonding layer and a transparent or translucent outer covering.
