The 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.

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 3^rd 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.

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

• Single and Twin Axis Goniometers
• Torsiometers
• Surface EMG
• Accelerometers
• Contact Switches & Event Markers
• MyoMeter
• Hand Dynamometers
• Pinchmeters

During recording the data is:-

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 meters
• 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
• 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

• 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 3^rd 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
• Option to record using Bluetooth® & MMC or MMC only
• Manual start with pre-set automatic stop

DataLOG Sensors, Software and Systems

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 3^rd 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. 

CONTACT 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.
