  • Industrial R&D for Ultra High Speed Continuous Paper Inkjet Printers:
    From 1998 to 2001, I have led teams developing the computer systems for ultra high speed inkjet printers which can print unique content on each page (traditional systems print the same content on each page). Design challenges: control algorithms to synchronise image delivery to high speed paper transport (>1 m/s), signal processing to suppress sensor noise and plant interference, high speed image generation (>30Mp/s from VLIW DSP and reconfigurable hardware platform). Design approach: abstraction of image generation machines, balancing load between configurable hardware and programmable DSP systems, efficient communications protocols. Some of the resulting intellectual property is protected with an international patent:
    • Phillip Musumeci, Multi Layer Continuous Paper Printer, International Patent Number WO011244, publication date 22-Feb-2001.
    This description of the project development team and time-lines includes an example of a 6-layer printer in Melbourne, Australia, attached to a modular high speed collator manufactured by Form Flo, Phoenix, Arizona. A 200 feet/minute single-layer printer handling 34cm wide paper was demonstrated at the 2000 DRUPA trade show, Dusseldorf, attached to a paper transport system manufactured by Dimuken, Kyoto, and using inkjet print heads manufactured by XAAR, Cambridge U.K. Some core team members have undertaken PhD study: Dr Evan Greensmith (ANU Systems Engineering 2005), James Webb (UNSW/ADFA Electrical Engineering, in progress...).

• Other Research Interests:

  • Regional Creative Industries: Justification of government support requires economic (and other) arguments based on evidence. As a member of a creative industries working party originally setup within the cluster group program of the Cairns Regional Economic Development Corporation, I was part of a small group of 3 who developed the survey questions for economic analysis to suit current 2006 industry and government requirements. This led to the launch of The Ideas Economy: Creative Industries - their size, worth and impact in Far North Queensland in May 2008.

  • Optimal Filtering and Array Processing: My PhD (Optimal Array Processing for Seismic Inversion, ANU 1989) developed array processing algorithms and 1-dimensional seismic inversion algorithms for use in tomographic analysis of earth structures. This is useful as more accurate knowledge of earth structure allows more efficient planning of overlay removal and/or resource extraction. Brief notes: 1-dimensional, 2-dimensional and 3-dimensional sensor (spatial) arrays are handled; seismic inversion used an analytic solution to lossy wave propagation within an "onion peeling" algorithm, work was carried out at the Australian National University, Canberra, with support from BHP Central Research Labs (now BHP Billiton) who used array filtering in the tomographic analysis of coal seams; supervisor was Darrell Williamson.

  • Image Coding: I have worked in a team performing research on coding algorithms that efficiently handle digital image sequences at different (but related) spatial resolutions from HDTV to videophone sizes. This was useful because it allowed better conversion between formats and researchers became more familiar with the techniques employed e.g. motion compensation, subband coding, Huffman and run-length coding, etc. This work was backed by ADFA, Telstra, Siemens, and the Australian Government, and was based at ADFA, Canberra.

  • Modern Control Applications: I worked with Bob Bitmead in the ANU Systems Engineering Department on design and implementation of optimal control algorithms to control speed of steam turbines driving sugar milling units. This was useful because we obtained better quality of control from less actuator use (i.e. better chute level consistency and less variation in turbine speed), and we also obtained more precise control (outputs vary in a smaller region of uncertainty) that made it possible to run the plant much closer to its limits (overall output and profit is higher). Extension of this work by others has resulted in more accurate control of a set of sugar milling units, less energy use, and in some instances the duplication of expensive sugar milling plant has been avoided. The CSR sugar mill at Ingham trialled these algorithms which included a Kalman filter to estimate plant model state and an LQG controller driving turbine speed. Bob is now with the department of Mechanical and Aerospace Engineering at UCSD.
