	Measuring activity
	The infrared sensors of the MLog system measure the activity of an animal by recording the body heat of that animal and its spatial movement. The activity is measured in all three dimensions in the range of the sensor. Since infrared radiation cannot pass through standard cage plastics, sensors in neighbouring cages do not interfere with each other. The system can be used with any cage size.

	Ten times per second
	Each sensor measures the activity of an animal ten times per second (10 Hz), independently of the total number of sensors in use. In competitive systems the data rate decreases with an increasing number of sensors. Although we work with a high data frequency, MLog can run over 24 hours a day 7 days a week and enables you to collect data for your research studies including for phenotyping or to simply monitor the health and welfare of your animals.

	Individual and pooled data
	You can divide the animals into groups (e.g. control and test doses) and the software calculates and presents the pooled data in real time. Thus you can compare the results of the different groups even while the experiment is ongoing.

	Real time data analysis and visualization
	At the same time, during the experiment the data are also being analyzed and can be presented in user friendly graphs and diagrams. This feature enables you to evaluate the experiment even while it is running so you can decide if you want to continue or stop the experiment and refine the selected parameters.

	Further processing of data and graphics
	The data, once collected, can be exported to other applications. Further individual data manipulations can then be conducted. All diagrams and graphics which have been generated during the experiment are saved in vector graphic format (wmf) thereby making them easy to integrate and work with in other programs.		Export filters for the data: .txt, .doc, .csv, .xls, .xml Export filters for the graphs: .bmp, .wmf, .emf

	State of the art network technology
	The sensors communicate with the computer via the TCP/IP protocol, the standard data communication protocol. Thus the data flow is fast and reliable and you can connect several hundreds of sensors to one computer. The sensors are linked with stable standard (Ethernet CAT-5) network cables whereby the same cable transports power and data simultaneously. This makes for very easy wiring.

	Remote control
	The MLog system can be accessed via the Internet or the Intranet so making it possible to control an experiment or to analyze data from virtually anywhere in the world. Thus our scientist clients can be based in one location with their experiments being conducted in another, distant location. And teams of scientists in multiple locations can run shared experiments and all be able to access their data.

	Phenotyping integrated in biocontainment systems
	MLog can be integrated into biocontainment housing systems such as the BioZone IVC systems (http://www.biozoneglobal.com). The ability to remotely control the experiment is ideal since it reduces the necessaity to enter the animal area either to perform experiments or to analyse data.

Phenotyping with the MLog system

The following list shows what kind of phenotypes can be detected with the MLog system based on the Mouse Genome Informatics (MGI) project that provides integrated access to data on the genetics, genomics, and biology of the laboratory mouse.
