IPC: A63H33/06
Filed: 1997-11-06
Abstract: A hollow block (e.g. a rectangular prism) preferably has six (6) perpendicular faces. Each face preferably has a wall with a particular thickness. An opening is provided in at least a particular one of the faces, and preferably in all six (6) faces. A hollow beam (e.g. a rectangular prism) preferably has six (6) perpendicular faces. Each face is preferably defined by a wall with a particular thickness. An opening is provided in at least a particular one of the faces, and preferably in the four (4) faces defining a closed loop, in the beam. Substantially parallel snaps extend from the other two (2) beam walls and have at their outer ends portions shaped to facilitate insertion of such snaps into the opening in the particular face of the block, retention of the snaps by the inner surface of the face defining the opening and removal of the snaps from the opening. Such portions are shaped for the beams to be pulled, peeled or bent from the block. When the block has has an opening in each of its six (6) faces, snaps from six (6) different beams can extend into the six (6) different openings in six (6) different directions in the block without any interference in the block from the snaps in the six (6) beams. In this way, complex structures can be formed from the blocks and the beams. Other structures such as vehicle ramps, building roofs, awnings and corbels can be disposed in a cooperative retionship with a structure formed from the blocks and the beams.

Title: Sterilization process using small amount of sterilant to determine the load
Inventor: JACOBS PAUL T
IPC: A61L2/20
Filed: 1999-12-22
Abstract: A method for determining and sterilizing a load in a sterilization chamber. A small amount of sterilant is introduced into the sterilization chamber and the concentration of sterilant is measured. The load of equipment to be sterilized is determined from the concentration of sterilant, and more sterilant is added, if necessary, based on the load. The process is repeated, if necessary, until the load is sterilized. The sterilant is preferably hydrogen peroxide, and the concentration of hydrogen peroxide is preferably determined by a spectrophotometric method in the infrared or ultraviolet regions. By monitoring the sterilant concentration and adding more as needed, the equipment in the chamber can be sterilized efficiently without exposing it to high concentrations of sterilant which could damage the equipment or leave too much residual on the equipment.

Title: Adaptive routing system and method for qos packet networks
Inventor: STILIADIS DIMITRIOS
IPC: H04L12/56
Filed: 2000-02-23
Abstract: A packet network employs routers that determine network routing based on quality of service (QoS) provisioning parameters and network topology information. QoS  provisioning parameters are provided to each router from a network management database, and the network topology information is determined from a link state database of the router.  The link state database may include network topology information collected by the router in accordance with the open shortest path protocol (OSPF). A network link, router, or other node failure initiates a new path-selection process. First, a temporary set of provisioning entries may be determined with a shortest path first (SPF) routing method. Then, the network packet flows may be classified into packet flows, real-time and non-real-time, and then as packet flows that require reserved bandwidth or that may be multiplexed. A multicommodity flow (MCF) routing method is then employed to determine an optimized set of candidate provisioning entries for the packet flows that may be multiplexed. The MCF routing method determines new routing for the packet flows based on QoS provisioning commitments as parameters. The MCF routing method determines the new routing based on an optimization criterion, such as maximized revenue. Once the new routing is determined, routing of network traffic is enabled by converting the provisioning entries into filter rules, which are then loaded into the packet classifier of the router.
Patent CA-2302927-A1 (CA)
Title: Mobile storage system
Inventor: JANSON STEVEN L
IPC: A47B88/04
Filed: 2000-03-29
Abstract: A storage assembly includes a storage cabinet removably mounted to a wheeled base which is supported by a supporting surface such as a floor. A guide assembly is interconnected with the floor and the base for guiding movement of the base in a longitudinal direction, so as to provide movement of the storage cabinet between an extended position and a retracted position in response to application of an axial pull-out or push-in force to the cabinet. A releasable retainer mechanism is interposed between the base and the guide assembly for releasably retaining the storage cabinet in either its extended position or its retracted position. The storage cabinet is removably mounted to the base by a removable mounting arrangement which requires a minimum number of tools to secure the storage cabinet to the base and which provides quick and easy mounting and demounting of the storage cabinet relative to the base.

Title: Echo canceller employing dual-h architecture having improved coefficient transfer
Inventor: LABERTEAUX KENNETH P
IPC: H04B3/23
Filed: 1998-11-13
Abstract: An echo canceler circuit (25) for use in an echo canceller system is set forth. The echo canceller circuit (25) comprises a first digital filter (35) having non-adaptive tap coefficients to simulate an echo response occurring during a call. A second digital filter (30) having adaptive tap coefficients to simulate an echo response occurring during the call is also used. The adaptive tap coefficients of the second digital filter (30) are updated over the duration of the call. A coefficient transfer controller is disposed in the echo canceller circuit (25) to transfer the adaptive tap coefficients of the second digital filter to replace the tap coefficients of the first digital filter when a value, E(~), is greater than a value E(-), and concurrently, when E(~) is greater than a value, E(sub max). The value of E(-) corresponds to the ratio between the signal-plus-echo signal and a second echo compensated signal using the second digital filter.
