The D4030 was one of the first products manufactured by Digitimer Ltd. It was developed from the Devices Ltd. range of Digitimers (Digital time interval marker & event release), products that gave us our company name. We are pleased to note that forty years later, several 2012 research papers have cited current use of D4030's. The D112 Pattern Reversal Stimulator was a projection-based system for studying visual evoked potentials, using a checker board pattern. 1972 1982 Digitimer 1972 - 2012 The DS7 High Voltage Constant Current Stimulator was originally developed in 1988 and remains in our product range as the updated DS7A (pictured) which is not only approved for human use within Europe but is also FDA cleared for marketing in the USA. 1992 The D180 High Voltage Stimulator, was the predecessor of our D185 stimulator and was primarily intended for high voltage nerve stimulation. Launched in 1972 and instantly recognised in laboratories worldwide, the NeuroLog System continues to provide researchers with a compact modular system for electrophysiological research. New modules continue to be developed today and all are designed to be backwards and forwards compatible. The DS2 constant voltage stimulator was first produced in 1980 but in 2000, Digitimer produced an updated version (DS2A-MkII) which was launched alongside a constant current equivalent, the DS3. Although Digitimer specialises in electrical stimulators, some of you may recall that we also developed the D190 Magnetic Stimulator in the late 1980's. Developed for transcranial electrical stimulation, the D185 MultiPulse is used as a motorevoked potential stimulator for intraoperative monitoring of spinal cord viability during surgery. The D185 has also found a role in the stimulation of in spinal nerves during diagnosis of peripheral neuropathies. The DS5 Biphasic Constant Current Stimulator has facilitated investigations of nerve excitability and provides clinical researchers with the ability to deliver computer generated stimuli. 2002 2012 The software-controlled D360 8-Channel Patient Amplifier was our first medically certified amplifier to be developed since the introduction of European laws relating to medical devices. The DS4 Biphasic Constant Current Stimulus Isolator allows a biphasic analogue voltage produced by a computer controlled DAQ system to shape an isolated current stimulus. Celebrating 40 Years of Support for Scientific Research & Medicine Grab Your Camera & Show Us Your Digitimer! Over the last 40 years Digitimer products have found their way to some exciting places, including at least two trips to Mount Everest and many appearances on television, so as part of our 40th birthday celebrations we thought it might be fun to collect some photos of Digitimer products in action or in other interesting situations. Alternatively, perhaps you have a candidate for the oldest Digitimer device still in use? You can Email your submissions to digitimes@digitimer.com (please limit each image file to <2MB). If there are any really eye-catching ones, we may even send out some prizes for the best entries! We will of course ask for your permission before publishing or reprinting any images submitted.
