Abstract: A method comprising passing a fluid through a negative sorting device. The negative sorting device produces a negatively sorted stream of the fluid from which any particles present in the fluid that are above a threshold size have been removed. The negatively sorted stream is analyzed to obtain a measure of a concentration of particles of interest in the negatively sorted stream. The particles of interest have a size that is less than or equal to the threshold size.

Abstract: A fluid dispenser including a fluid outlet for dispensing a fluid onto a user’s hand, and a fluid collector for collecting at least some of the fluid after the fluid has contacted the user’s hand. The fluid dispenser further includes a sample preparation mechanism for generating a sample from the fluid collected by the fluid collector, the sample being removable from the fluid dispenser for external analysis.

Abstract: A hand cleaning system comprising a hand cleaning fluid dispenser configured to dispense an output fluid onto a hand of a user, and a fluid adjustor. The fluid adjustor is configured to automatically adjust a composition of the output fluid. The composition may be selected based on various considerations, such as: the health status of the user; the pH of the hand; the identity of the user; the history of the user; the schedule of the user; the predicted likelihood that the user has an infection; microbes detected on the hand; the moisture level of the hand; the concentration of one or more chemicals on the hand; an allergy profile of the user; and a chemical sensitivity profile of the user.

Abstract: A system including a plurality of fluid dispensers for dispensing hand cleaning fluid. At least some of the fluid dispensers are configured to analyze at least some of the hand cleaning fluid after the hand cleaning fluid has contacted a user's hand. The system is configured to detect and/or predict an infection based at least in part on the analysis of the hand cleaning fluid. The system is preferably capable of predicting the spatial and temporal distribution of an infection.

Abstract: A method of analysing and identifying particles in an input fluid by electrical field analysis preferably in combination with imaging analysis and towards establishing characterises of the particles that can be compared with characteristics of known particles, preferably biologic particles such as bacteria and viruses. Preferably in a focusing step, the particles are focused as in a microfluidic particle sorting cartridge followed by electrical field analysis to determine impedance data. Preferably, the electrical field analysis is carried out in a water and alcohol solution.

Abstract: A fluid dispenser with a pump mechanism that dispenses fluid when activated. A light sensor detects light in or around the fluid dispenser, and a controller controls a function of an electronic component of the fluid dispenser based on detection data received from the light sensor.

Abstract: A direct isopropanol fuel cell adapted for use in ambient conditions and utilizing as fuel isopropanol and water preferably with isopropanol at relatively high concentrations representing 30% to 90% isopropanol.

Abstract: A hand cleaning fluid dispenser for dispensing fluid onto a user's hand includes a time of flight sensor to determine a distance of a hand of a user below an outlet of the dispenser from which the dispenser when activated dispenses the fluid and a controller to activate the dispenser to dispense the fluid from the outlet when the hand is sensed to be within a predetermined range of distances below the outlet.

Abstract: A hand cleaner fluid dispenser, including a reservoir for containing hand cleaner fluid to be dispensed; a dispenser outlet for discharge of the hand cleaner fluid from the reservoir; and a discharge mechanism operable to discharge a drop of the hand cleaner fluid from the dispenser outlet when activated. A levitator device is incorporated into the hand cleaner fluid dispenser, and is operable to levitate the drop of hand cleaner fluid at a position where the drop is accessible to be taken by a user's hand.
