Title: Wood rot protector
Inventor: SHAW JOHN G
IPC: E04B1/70
Filed: 1999-10-05
Abstract: A wood rot protector for use portions of lumber liable to accumulate moistrue, and having a protector for attachment over the upper edge of a portion of lumber, the protector having a web overlying the upper edge of the lumber, and in some cases having side walls, an upper surface of the web having a central planar median strip. In one embodiment the protector is in the form of a planar strip having angled side edges extending outwardly from the edges of the lumber to a width greater than the width of the lumber to carry moisture away from the lumber and allow it to drip downwardly.

Grooves may be formed on the upper surface of the median to prevent migration of moisture along the upper surface.
Patent CA-2287890-A1 (CA)
Title: Systems and methods for handling emergency calls in hierarchical cell structures
Inventor: RAITH ALEX K
IPC: H04W4/90
Filed: 1998-04-01
Abstract: Emergency call handling may, in the near future, require terminal unit location information to be provided to emergency service centers (8).  Exemplary embodiments of the present invention facilitate the provision of this information by reducing a number of monitoring stations needed to track terminal location based upon control channel access. First, mobile units placing emergency calls can be forced to use designated control channels which may differ from control channels to which they are currently listening.  Second, mobile units may be required to transmit at greater than specified power levels so that monitoring stations receive their emergency call access.

Patent CA-2300190-A1 (CA)
Inventor: THUDT RAIMAR
IPC: H04L12/70
Filed: 1998-07-27
Abstract: During ATM communications a plurality of communications are transmitted through common link sections. New incoming communications are allowed on the basis of decisions made by acceptance algorithms. However only yes/no decisions are made. It is nevertheless desirable that the reserved band width required for all the communications carried out by said link sections be known. This problem is solved by the invention whereby the band width is evaluated by steps while communications are being set up/switched out, by modifying the sigma rule algorithm.
