Abstract: This invention relates to a system and method of monitoring hygiene standards compliance in a medical facility in which there is provided a surveillance network having a monitoring unit 3 and a plurality of mobile network units 7. There may additionally be provided a plurality of fixed network units 5. The monitoring unit 3, mobile network units 7 and fixed network units 5 are connected by way of a Wireless Personal Area Network (WPAN), in this case a ZigBee network. Identification signals are sent from the mobiles network units 7 to the monitoring unit 3 and the monitoring unit stores the identification signals in memory and generates a hygiene standards compliance profile for an individual associated with a particular mobile network unit. The hygiene compliance profile may provide information relating to the number of times that a particular individual washed their hands to information regarding the patients that that individual came into contact with over the course of a shift.

Abstract: This invention relates to a system (3) and method for monitoring the location of a mobile network unit (9) in a low-power localised wireless communication network (10) such as a wireless personal area network (WPAN). The WPAN could be a ZigBee network. The system (3) comprises a localised wireless communication network (10) having a control unit (5), a plurality of fixed network units (7) and a plurality of mobile network units (9). The mobile network units (9) transmit identification signals and two or more fixed network units (7) receive the identification signals directly and calculate the strength of the identification signals. This information is transmitted to the control unit (5) where the control unit processor calculates with a high degree of accuracy the position of the mobile network unit (9). It is possible to track and plot the location and movement of one or more mobile network units.
