Lithium-ion batteries go solar racing with Solion

February 26, 2008 – 10:45 am
Solion is using VL E high energy, lightweight rechargeable lithium-ion cells to create high performance 'plug and play' battery packs designed specifically for solar powered racing cars Solion, a spin-off company from the University of the South Bank in London, is working in close co-operation with Saft to use its VL E high energy, lightweight rechargeable lithium-ion cells to create high performance 'plug and play' battery packs designed specifically for solar powered racing cars. The onboard batteries, which incorporate a sophisticated electronic management system essential to ensure the safe and reliable operation of lithium-ion cells, are used to store solar energy to power the car during low light conditions as well as providing a boost in power for climbing hills. Solar racing cars compete in two main races, the World Solar Challenge (WSC) - a 3000km race across Australia - and the American Solar Challenge (ASC) - which this year followed Route 66 ...

Lithium batteries vital in flight defibrillators

February 26, 2008 – 10:44 am
How the LO26SHX lithium sulphur dioxide 12 Volt primary battery pack powers LIFEPAK 500 automated external defibrillator The LIFEPAK 500 automated external defibrillator (AED), now carried as standard equipment on each of British Airways' 250 aircraft, is powered by a long-life, high power Saft lithium sulphur dioxide battery pack. This primary (non-rechargeable) 12 Volt battery will not only power the LIFEPAK for around 300 individual discharges, it also enables the equipment to remain unused for up to four years yet still be relied on to power up immediately should an emergency arise. AEDs are designed to enable people without extensive medical expertise to treat ventricular fibrillation (VF) the most common cause of sudden cardiac arrest. In VF the heart quivers ineffectively and is unable to pump blood throughout the body, The AED supplies a powerful electrical shock, known as defibrillation, that interrupts the VF and allows the heart's normal rhythm to regain control. Without ...

Bias control for lithium niobate modulators

February 26, 2008 – 10:43 am
The MBC-LN series of modulator bias controllers is specially designed to optimise the performance of lithium niobate modulators in systems and laboratories Lithium niobate (LiNb03) modulators have proven robustness and high reliability. They have been widely used since the mid-1990s in long-haul optical networks for their ability to modulate optical signal from laser diodes with short transition times and without chirp. Thanks to their broad wavelength performance, they currently also offer modulation solutions to fibre lasers, widening the scope of applications of those sources. LiNb03 intensity modulators are Mach-Zehnder type interferometric devices that exhibit a cosine transfer function. Although highly stable components, their working point can suffer slow drift due to strong variations of external conditions. The Photline MBC-LN family of bias controllers are specially designed to stabilise the working point of LiNb03 Mach-Zehnder modulators. They use digital signal processing based on an original FFT principle that allows users to easily change the dithering frequency ...

Colorimetric lithium

February 26, 2008 – 10:42 am
Claimed to be the first fully automated, colorimetric assay for the direct quantitative determination of lithium levels in serum Exclusively from Alpha Laboratories, the first fully automated, colorimetric assay for the direct quantitative determination of lithium levels in serum. The liquid presentation, ready to use on most clinical chemistry analysers, eliminates the traditional use of flame photometry, ISE and atomic absorption. The assay is fast thus providing short turnaround time for improved patient care. The assay is linear to 3.0mmol/l, provides excellent correlation to flame photometry and a calibrator is also available.

Pulses Plus lithium battery on show at ECIF

February 26, 2008 – 10:41 am
CMP Batteries Standby Division will be showing the new Pulses Plus lithium battery at ECIF this year, a technology which offers an outstanding combination of operational advantages Apart from the many batteries in their range, CMP Batteries Standby Division will be showing their new Pulses Plus lithium battery at ECIF this year. The technical requirements for lithium batteries used as the main power source in applications with long operating lives have changed drastically. The electrical current profile typically consists of a low continuous current of some micro Amperes coupled with high pulses in the range of hundreds of milliamps and up to several Amperes for several milliseconds or even seconds. The lithium thionyl chloride technology in bobbin-type construction is the most suitable solution for low-current applications, due to its high energy density, very low self-discharge rate and proven shelf and operating life of more than 10 years. However, for reasons of construction, the currents ...

Gas monitors watch out for hydrogen sulphide

February 26, 2008 – 10:39 am
The new Model 2180A single channel and 2280A four channel hydrogen sulphide gas monitors from General Monitors represents the next generation in highly reliable, simple, cost-effective gas detection Process and plant engineers concerned about protecting people and equipment from the dangers of hydrogen sulphide gas will find the new Model 2180A single channel and 2280A four channel hydrogen sulphide gas monitors from General Monitors represents the next generation in highly reliable, simple, cost-effective gas detection. Hydrogen sulphide gas is highly toxic and deadly in concentrations of 500-700ppm within 30 to 60min. In low concentrations, hydrogen sulphide is easily detected by the smell of rotten eggs. This gas, however, rapidly desensitises the olfactory nerves in the nose and so the sense of smell very quickly becomes an unreliable warning. Workers may suddenly collapse with little or no warning when the gas is present in higher concentrations. The new Models 2180A/2280A hydrogen sulphide gas monitors are designed specifically ...
