PRODUCT SHOWCASE Philips calibration lab takes to the road Philips’ Calibration Laboratory has created a mobile test centre, taking international standard electronic measurement equipment directly to customer premises. The mobile “Cal Lab”, housed in a temperature and humidity controlled Isuzu 2-tonne truck, needs only a 3-phase outlet at the location to perform a range of calibration tests. This will reduce the normal 10-day turnaround on instrument calibration to just a single day and in some cases to a few hours. This is expected to be a major bene­ fit to small and medium-sized businesses which usually don’t have the workload or the financial wherewithal to justify back-up test equipment. While there was no problem with the quality of Philips’ calibration service at its Moorebank (Sydney) laboratory, there was a real problem in the time taken, with obvious implications for productivity. Now businesses from Newcastle to Wollongong can have the same quality BassBox ® Design low frequency loudspeaker enclos­ures fast and accurately with BassBox® software. Uses both Thiele-Small and Electro-Mechanical parameters with equal ease. Includes X. Over 2.03 passive cross­over design program. $299.00 Plus $6.00 postage.

Intended for the hobbyist market, these will also find wide acceptance by technicians, QC/QA personnel and others who need a close-up view. There are four in the range, starting with a jeweller’s eyepiece (the type you see in gangster movies where the “fence” places the glass in his eye to examine the diamonds the crook has just brought in). This is priced at $3.00 and has a plastic lens. The top three in the range all incorporate two glass lenses, and are intended to be used where the loupe is placed close to the object (print, insect, coin, etc) to be magnified. The focal point is just below the base of the loupe. The smallest, priced at $8.00, is 50mm in diameter and has a magnification of 10 times. Next up is the 75mm model ($12.00), while the largest is a healthy 110mm and is priced at $15.00. All these are available by mail order direct from Oatley Electronics, 5 Lans­downe Pde, Oatley West 2223.

They are designed for security applications in banks, hotels, casinos, service stations, restaurants and similar locations where cash, valuables or people require monitoring. The TLS-924P is capable of up to 24 hours of time lapse recording. With a horizontal resolution of 350 lines (B&W), the 4-head unit gives excellent VHS picture quality. Multiple recording modes also allow audio recording. Single fields can be taped one by one and also viewed separately during playback. Timer recording can be set on a daily or weekly basis, and all settings are made and confirmed via an on-screen display. If the unit is triggered (for example by an alarm sensor or duress switch), it automatically switches to an alarm recording (3 hour) mode, giving a complete recording of the event that triggered the alarm. Furthermore, an alarm scan function allows playback every five seconds of an alarm functioning. The TLS-S2500P is similar but comes in a super VHS format with more than 400 lines of resolution, even in time-lapse mode. With this model, it is also possible to record in various multiples of hours, right up to 960 hours (40 days). Sanyo video surveillance products are distributed in Australia by Javelin Electronics, phone (02) 684 4477 or fax (02) 684 2187. 100W DC-AC inverter for consumer products While many of today’s consumer electronic items offer both mains (240V) and low voltage operation, there are significant numbers that do not. Even items which use rechargeable batteries often have no provision for charging, except via a 240V outlet. Using such items away from a power point (in a vehicle, for example) has long been a problem. Powerbox Australia has solved the problem with their Motormate, a 300 watt peak or 100 watt continuous 12V DC to 240V AC inverter, which is designed to run direct from a vehicle’s cigarette lighter.

It integrates voice and data communications which can be used independently or as together. For example, the user can dial a voice call from the address book in the PC or access the address book for fax numbers while in the fax application. The PC side also incorporates a range of built-in business and personal management software, which are all integrated. Because of the unit’s small, unobtrusive format, note taking, data search and even sending and receiving of faxes can be made virtually anywhere, even during meetings. Only data communications and e-mail require any configuration to operate. The OmniGlo 700LX is said to be intuitive, and user friendly to all messaging services of the GSM (global system for mobile access) network, including voice, data, fax and short messaging services. As these services are already in place in many countries around the world, the international traveller using an OmniGlo 700LX can take advantage of the international roaming agreements which exist between service providers.
