Patent CA-2222083-A1 (CA)
Title: Safety harness attachment post assembly
Inventor: PALMER THEODORE R
IPC: A62B1/04
Filed: 1997-11-25
Abstract: A post assembly for attaching a worker safety harness to a structure comprises a post member having two transversely spaced wall attachment assemblies at its lower end and on opposite sides thereof and a roof attachment assembly intermediate its ends, the assemblies being releasable to enable the post assembly to be removed while the parts attached to the wall and roof remain for re-use.   The assemblies have attachment axes that diverge toward the wall to increase the transverse spacing between the attachment points as the spacing from the wall increases.   The spacing of the wall assemblies and their placement on opposite sides of the post ensures that part of any sideways acting force is converted from undesirable shear peeling force to compressive force on one wall assembly and tension force on the other assembly.   The part of each attachment assembly that contacts a surface may comprise a central plate with one or more side and/or end plates hinged thereto to accommodate curvature of the roof surface.   Preferably, the attachment members are fastened to the structure surfaces by adhesive.   The post member comprises an upper telescoping part so that its length can be adjusted as required, and a lower telescoping part to adjust the vertical distance between the wall and roof assemblies.   A stub post assembly is used for installation to ensure that the attachment plates are accurately located for subsequent re-use.

Patent CA-2237743-A1 (CA)
Title: Oa&m system
Inventor: HAMEL PIERRE A
IPC: H04Q3/00
Filed: 1998-05-14
Abstract: An OA&M system is provided for a network communication core having a switch, a controller, and a core configuration memory. All configuration information which is static (i.e., information which remains the same regardless of the configuration of the core) is placed off-core in a map file. Because of this, requests for information on the configuration of the core may often be satisfied without the need to query the core, thereby reducing core load. Further, this static information in the map file allows validation of requests for dynamic configuration information as well as requests for reconfiguration of the core. In other words, the static information assists in ensuring that requests are proper. The static information in the map file is presented as "list", "attribute", and "choice" features. This presentation facilitates the making of OA&M requests by a user. The features become arguments of functions in order to generate OA&M requests to the controller. Each function received by the controller is converted to instructions for the core by an interface and a map file in the core. The features in the off-core map file are organised into a hierarchical tree (a feature tree) and the off-core map file may be accessed by a browser program of a personal computer so that levels of the tree may be displayed, thereby facilitating quick configuration requests.
