Four Projects in Review - Engineering Harmonics

Engineering Harmonics is a Toronto based engineering company that has worked on a multitude of signature projects. Phil Giddings, President, will provide a brief history of the firm, discuss it services and markets and outline the challenges the firm faces in entering the international market.

The following four projects will be discussed:

Mile One Stadium

- This is the new home of the St. John's Maple Leafs hockey team of the AHL. The arena features a fully distributed system of lightweight loudspeakers suspended over the dasher boards and facing the spectators. Two clusters of similar loudspeakers are suspended over the ice to cover the ice surface with the capability for the future addition of subwoofers for enhanced musical "punch". The loudspeaker system features digital signal processing, which allows flexibility and control for different types of events. Team and production intercom systems are provided, as are connections and routing for sound connections to press and outside broadcasting trucks. Paul Alegado will be the presenter.

House of Commons - Committee Room Prototype

- Engineering Harmonics is currently studying, analyzing and planning multi-media systems for the House of Commons and the Parliamentary Precinct in Ottawa. This program is part of the long-term architectural renovations of Parliament Hill. One current project is the redesign of committee rooms from a first principles basis. In order to test various aspects of the Committee Room, a prototype room is being constructed. Our work is in assisting the House in the Technical Design and Testing of Multimedia in the prototype. Jeff Bamford will review the design of the multimedia systems and how that design was meticulously arrived at.

Walt Disney Concert Hall - Dave Clark will discuss this concert hall that will be the new home of the Los Angles Philharmonic Orchestra. The concert hall is a 2300 seat venue. Frank Gehry has designed the building. As such, it is a room with significant architectural constraints. Two systems have been designed: a retractable main system for contemporary programs and an "invisible" system for announcements and narrative. The systems will both use fully digital processing. The system has been designed to be quickly reconfigured from one event to the next.

IBM Canada's Executive Briefing Centre

- Phil Giddings will review this project. IBM uses this centre for multimedia presentations and demonstrations that examine the broad impact of the Internet and the importance of networked communications to the sharing and use of information. The new campus, completed in 2001, features one of the first corporate IP-based video conferencing facilities in Canada and an advanced dual projection display system. Special design considerations for this project included the assessment of network addressable control and projection technology.
