Abstract: The present invention relates to a system for monitoring contact or close proximity between one or more sources of contact within an environment and to one or more devices suitable for implementing such a system. Each source of contact is provided with a monitoring device. Each monitoring device comprises an indicator unit and a detecting unit. The indicator unit is operable to emit a signal and the detecting unit is operable to detect and identify signals of the type emitted by the indicator unit of another monitoring device and output an information signal indicative thereof.

Abstract: The present invention relates to a system suitable for monitoring the contamination potential associated with one or more mobile objects within an environment containing one or more fixed or mobile sources of contamination or cleansing. The system comprises a plurality of signal indicator devices connected to the or each source, each indicator device emitting a signal. The system further comprises a monitoring device connected to the or each object, the monitoring device being operable to: detect signals of the type emitted by an indicator device; infer the occurrence of contact between an object and a source from a detected signal; determine a level of contamination risk from the inferred contact; and output a status signal indicative thereof.

Abstract: The present invention relates to a contamination monitoring device for monitoring contamination potential associated with a user. The device comprises attachment means for holding the device in proximity of the user, a sensor being operable to detect the presence of a washing action and output a signal indicative thereof and an indicator being operable to receive signals output by the sensor and output an indication in response thereto.
