DLL (dynamic link library) for real time data transfer to other applications

     
The NEW DataLOG W4X8, incorporating Bluetooth® Wireless and MMC Flashcard technologies, provides unparalleled portable data capture and real time display and analysis.

DataLOG has been developed to meet the demanding needs of researchers for ambulatory monitoring in a variety of settings including medical, industrial ergonomics, sports science, biomechanics, human performance, veterinary science, and educational facilities.

     

DataLOG is a general purpose, programmable Data Acquisition Unit allowing the user to collect both analogue and digital data from a wide range of sensors. 

During all stages of the design and development process, attention has been given to the Bluetooth® Wireless link, providing real time data transfer and display.  In addition, the data is automatically backed up to the MMC Flash Card providing complete peace of mind. The system incorporates a DLL (dynamic link library) enabling the researcher to readily develop a real time data stream into 3rd party programs such as Microsoft Visual Basic or Visual C++.   

The DataLOG is configured from the host PC using the Bluetooth® wireless link, including simple adjustments per channel for gain, power supply, sampling rate and datum settings.  When Biometrics’ sensors are connected these parameters are automatically set using a drop down menu.

   
All Biometrics Ltd sensors readily connect to the DataLOG including:-    

Single and Twin Axis Goniometers

Torsiometers

Surface EMG amplifiers

Accelerometers

Contact Switches & Event Markers

Myometer

Hand Dynamometer

Pinchmeters

     
 

The front end amplifier configuration and sensor power supply are programmable enabling the researcher to also connect a wide range of general or custom transducers including:-

Load cells

Strain gauge devices

Single ended voltage inputs

Differential voltage inputs

Temperature probes

Flow metres

Microphones

DataLOG's graphics LCD provides a display of the unit status and a simple user interface. A keypad provides the following facilities:-

·         Manual start and manual stop recording

·         Manual start with pre-set automatic stop

·         Zero a specific channel or all channels simultaneously

·         Erase the last recording or all recordings

·         Display of real time inputs as numerical values in engineering units or as bar graph

·         Option to record using Bluetooth® & MMC or MMC only

 
                 

During recording the data is:- 

·         displayed and analysed real time within the PC using Bluetooth®

·         stored on the PC and auto-backed-up to the MMC Flash Card

·         transferred real time by the Dynamic Link Library into 3rd party programs using tools such as MS Visual Basic or Visual C++

·         stored as ASCII or as a standard Sound Wave file for passing into other applications such as Microsoft Excel or Cool Edit 

·         Displayed real time on the DataLOG Graphics Display in engineering units, or as a bar chart, or as adjustable audible alarms

The PS850 Portable EMG System is dedicated to portable EMG measurements and comes with the DataLOG, Management & Analysis software, 8 active EMG sensors, R206 earthing strap, T350 adhesive tape and IS3 event marker.

 

The PS900 Portable Goniometer & EMG System combines movement analysis with surface EMG measurements in a complete east to use, affordable system and comes with the DataLOG, Management & Analysis software, 8 goniometers (choice of sizes to accommodate upper & lower extremity), 8 active EMG sensors, R206 earthing strap, T350 adhesive tape and IS3 event marker.

         

Synchronization Options for 16, 24 or 32 Channels

For applications requiring greater than 8 analog or 4 digital channels, the DataLOGs are set-up in record to MMC card only mode, and then multiple units may be synchronized using one of the following cables:-

SYNC2            To synchronize 2 DataLOGs for up to 16 analog and 8 digital channels of data acquisition recording to MMC card only.

SYNC3            To synchronize 3 DataLOGs for up to 24 analog and 12 digital channels of data acquisition recording to MMC card only.

SYNC4            To synchronize 4 DataLOGs for up to 32 analog and 16 digital channels of data acquisition recording to MMC card only.

The DataLOG Display & Analysis Software may open an unlimited number of data files and the time axis may be tracked across all files allowing display & analysis for a large number of channels.

 
DataLOG Accessories                      

SYNCHRONIZATION CABLE SYNC 1

For remote start / stop by a TTL signal {i.e. the ability to switch a signal line from logic 1 (+5V) to logic 0 (+0)} sent from other hardware systems to synchronise data collection from multiple sources.  The SYNC1 is a 2 metre cable with a connector at one end to connect to the digital input socket of the DataLOG and 2 flying wires at the other end.  Alternatively, this cable may be specified with any connector of choice. 

SYNCHRONIZATION CABLE SYNC 1BNC

A synchronisation cable with a BNC connector fitted for interfacing to certain 3rd party systems such as Qualisys or Vicon.  Connector chassis is wired as common or ground.  NOTE:-  Please contact Biometrics Ltd or the 3rd party equipment manufacturer for specific instructions before this cable is used.     

OPTICAL SYNCHRONIZATION using Start Switch IS2-LED

A 1.8 metre cable with a suitable connector at one end to temporarily connect to the DataLOG, and a hand held switch with LED at the other.  Pressing the switch will activate the start recording function and illuminate a LED which may be used for precise synchronization with all camera based motion analysis systems.

EVENT MARKER IS3 

A 1.8 meter cable with a suitable connector at one end to connect to the DataLOG, and a hand held switch at the other.  This useful accessory allows time marks to be superimposed on the recorded data.

FORCE SWITCH ASSEMBLY FS4

An assembly of 4 Force Sensing Resistor Sensors (FSRs) each on 1.2 meters of cable which are readily connected to the DataLOG via one connector for use as switches to indicate contact e.g. heel and toe strike or palmer contact.  The sensors are thin and robust and are usually placed inside the subject’s shoe or glove for convenience.
