they are Quiktrak patents...........maybe you should check a little more.
In 1985, Dr Yerbury started Advanced Systems Research Pty Ltd (ASR), and assembled a team to design and build the technology that has become known as ‘QuikTrak’. This technology was further developed under the stewardship of Lend Lease Corporation and eventually British Aerospace Australia, culminating in a prototype system becoming operational at the end of 1987.
In 1996 a new commercial QuikTrak network in Sydney was commissioned and since then the system has proved its worth operationally, particularly in the effectiveness of its security applications where it has saved many millions of dollars worth of private vehicles and an equally large quantity of commercial cargoes.
In late 1999 QuikTrak acquired the Intellectual Property for the QuikTrak technology from British Aerospace, including our Technology Centre in Adelaide. Shortly afterward, two new QuikTrak networks were established covering the greater metropolitan areas of Melbourne, Brisbane and the Gold Coast.
