Electrogoniometer
We have a selection of twin axis electrogoniometers which permit the simultaneous measurement of angles in two planes, e.g. wrist flexion/extension and radial/ulnar deviation.
We have various display and recording instrumentation for both routine clinical measurements and specific research applications (Angle Display Unit; Data LOG and Data LINK).
Technical
Angle display unit
This is used with the Biometrics angle measurement sensors (goniometers) displaying real time display of joint angle data. The sensors are attached across the joint to be measured and connect to the battery powered Angle Display Unit. Static angles are viewed on the LCD, or alternatively dynamic movements may be monitored.
Data LOG
This is a fully portable subject worn programmable Data Acquisition Unit (battery powered) allowing the user to collect data from a range of sensors. The sensors connect to the data logger which has programmable instrumentation amplifiers and programmable power supply responsible for energizing the sensors, sampling and converting the inputs into digital signals. The data is stored on a MMC card in flash memory and is easily transferred to disk for further storage or display and analysis within the Biometrics' Display and Analysis Program. Alternatively, the data may be converted into ASCII or standard Sound Wave file format for passing into other applications such as Microsoft Excel or Cool Edit. During recording real time visual feedback is obtained from the LCD as a direct digital readout in engineering units, or alternatively as a bar chart.
Data LINK
This is a general purpose subject worn programmable Data Acquisition System allowing the user to collect data from a range of sensors. The sensors connect to a small, lightweight Subject Unit with programmable instrumentation amplifiers and power supply responsible for energizing the sensors, sampling and converting the inputs into digital signals. The data is transferred from the Subject Unit to the table top Base Unit via a RS422 data transfer cable (7 meters in length). The Base Unit connects to the host PC via a RS232 serial cable where the data may be readily stored on disk as ASCII or passed real time into other applications such as Microsoft Excel or Microsoft Visual Basic using the DLL (dynamic link library). Real time feedback is obtained from the main data display window. Additionally, real time analogue outputs may be obtained using the optional output cable type no. R2000I.
