PRODUCT SHOWCASE The ultimate hard disk music storage system? Looking for somewhere to store (and retrieve) all your music? Linn Products have a solution – if you’re prepared to pay for it! The Kivor Index music library is a storage/retrieval and playback harddisk-based system that can be used as a stand-alone unit or together with other Knekt Kivor products. It provides up to 500 hours of full bandwidth, pitch accurate hard disk music storage and allows up to eight users to have concurrent access to high quality, full bandwidth music in a multi-room system or a hard disk component source in any audio system. Whether you have a huge library of LPs or CD discs, or like to download MP3 music, the Kivor Index hard disk records and creates playlists of your favourite tracks by genre, artist, mood or date. Available in two configurations, the Kivor Index provides either 250 or 500 hours of storage that can be increased up to tenfold when using compressed audio. Music is simply loaded into the Kivor Index via its integrated CDROM and a built-in modem downloads Internet material for ‘manipulation’ on Linntek, Linn’s PC set up and control utility software. Available in either black or silver, the Linn Kivor Index music library is rack mountable for installation with any multi-room amplification system.

The Managing Director of Powertec, Mr Ray Smith, says the new diverter revolutionises the manner in which small and/or home business operators are charged for landline calls diverted to mobiles. “At present whenever a home or office telephone call is diverted to a mobile phone the owner pays charges for the diversion, in conjunction with the caller paying costs as well,” said Mr Smith. “The new Powertec CellularDiverter turns that landline component into a mobile call, so users can then benefit from special mobile-to-mobile rates,” he said. “This means that a 10 minute diverted call which would normally cost up to $2.50 will now only cost 20 cents,” he added. “Any business making calls to mobiles or receiving calls from their own mobiles can take advantage of the new cost saving system even when they do not use the diverter,” he said. Mr Smith says the new Powertec Cellular Diverter is the result of more than two years of research and development, at a cost of thousands of dollars. He says the device is Australian compliant and has patents pending. They are used in conjunction with the Ericsson Fixed Cellular Terminal which was released on the Australian market, late last year. Powertec is offering to loan the system to approved customers at no cost to prove that the technology is beneficial in saving on phone bills for small business and home users.

APC’s NetworkAIR Rack Mounted (RM) Air Distribution unit works in tandem with an existing precision air conditioning system in enclosed environments to pull air from beneath the raised floor directly into the rack enclosure, before it can mix with room air. It eliminates dangerous hot spots in data centres by boosting the conditioned air volume within the rack itself and improving air delivery in poor static pressure areas. In environments without raised floors, the NetworkAIR RM Air Distribution unit uses air from under and around the bottom of the rack or enclosure where the air is coldest. This boosts the amount of air supplied to ensure the necessary amounts of airflow to equipment.

They represent the next generation of wireless equipment offering both robust construction and a choice of a both high power (200mW) and standard (100mW) models. They are ideal for wireless ISPs. The detachable external antenna further enhances their overall perfor- mance. If you use them with a high gain antenna, make sure you don’t exceed the 4W EIRP legal limit. They support both peer-to-peer and infrastructure communications and are usable with WiFi (WECA) certified products. Operating systems supported include Win 95, 98, 2000, NT, ME and XP. Memory size is 128K x 16 SRAM and 128K x 8 flash ROM.

The problem: the Kasuga controller was: “Old and slow – a case of a still young body under the direction of an old, slow brain!” said Roy Milan of JAR. But scrapping the machine and buying a new system would have involved a large capital investment. Instead, JAR Engineering contacted H & H Machine Tools and investigated the possibility of a controller www.siliconchip.com.au transplant. The result: the Kasuga is now working at double the previous feed rate. Mr Milan says: “The system used to operate in a jerky, stop, start motion. The new Fidia controller provides a continuous smooth movement and reads at a very high rate of knots. We are frequently recording savings of $500 a day or higher —savings that will rapidly pay out the upgrade cost.” He adds that his company has found the Fidia controlled machine “very user friendly, with the need for operator training minimised.” Contact: H&H Machine Tools Ph: (03)9719 7729, Fax: (03) 9719 7298 email: gmann<at>h-h.com.au March 2003  55
