Patent CA-2357568-A1 (CA)
Title: Labeler for pipes, conduits, tubes, and rods
Inventor: BOIRE MARTIN C
IPC: G09F3/00
Filed: 2000-01-18
Abstract: A pipe or conduit labeler includes a saddle leg (27, 28) having an inside diameter equal to or slightly smaller than an outside diameter of a pipe or conduit (16) to be labeled. The saddle leg is molded to a saddle stem (12) which in turn is molded to a sign plate (15). A user either writes useful information directly on the sign plate or affixes a pre-made label to the plate. The sign plate optionally includes raised lettering or information such as an arrow pre-molded on the plate or Braille characters. The labeler resiliently clips onto the pipe or conduit being labeled. More complex variations include extending arms and moveable joints enabling the identification of pipes which are at difficult angles or out of direct sight of a user.

Title: Method of addressing physical problems of a topological network using a topology engine
Inventor: WIGHT MARK S
IPC: H04L12/24
Filed: 2001-11-08
Abstract: The topology of a network is represented, or emulated, by a topology engine comprising processing elements interconnected via a connection matrix. Queries representing physical problems of the network are supplied by a host processor to the topology engine, where they are processed in the processing elements in accordance with the topology to produce responses which are returned to the host processor. In particular, the network can be a communications network and the queries can comprise search requests for determining connection paths between devices of the network. The topology engine can use processors with multiple instances so that it is more compact than the communications network that it represents.

Patent CA-2378139-A1 (CA)
Inventor: LINDGREN FREDRIK
IPC: A61F11/14
Filed: 2000-06-20
Abstract: The present invention provides an earmuff device comprising an earmuff cup having at least a window portion which is formed of an optical material whic h transmits light rays in such a way that the human eye can see through the material to a degree that an earplug or other object inserted within the ear  is visually perceivable to the human eye. In other words, the earmuff cup is  formed of a transparent material or a translucent material so long as the earplug inserted within the wearer's ear is visually perceivable through the  translucent portion of the earmuff cup. Because the earmuff cup is formed of  a material that permits an individual, such as a supervisor or hearing conservationist, to perceive whether an earplug is inserted within the wearer's ear, the earmuff device of the present invention is particularly we ll suited for use in a dual hearing protection environment in which the previou s method of compliance monitoring was time consuming and difficult.
