A wireless time-of-flight distance measurement device and/or a motion detector is used at each of a plurality of stations in a wireless network in an enclosed facility to accurately locate a badge-wearing person near the station. The location, badge number and time of detection are transmitted through the network and stored in a computer memory. In a health care facility, hand-washing detectors are located at some of the stations and caused to energize a hand-wash status indicator light on the badge when the wearer has washed his or her hands. The light remains “on” for only a certain length of time, but will be extinguished sooner by a monitor device near each patient when the health care worker leaves the vicinity of the patient. These events also are transmitted and stored so that a timed record of each worker's hand-washing and visits to patients is created.

A method for investigating a target environment to determine whether or in what amount a chemical species may be present therein, which comprises: (a) exposing to said environment an article of manufacture comprising a multiplicity of particles in close-packed orientation, said particles having a core of conductive metal or conductive metal alloy and deposited thereon a ligand which is capable of interacting with said species such that a property of said multiplicity of particles is altered; (b) subjecting said multiplicity of particles to conditions sufficient for said property to be exhibited; and (c) monitoring said property to determine whether there is, or the amount of, any change as an indication of whether, or in what amount, said species is present; a multiplicity of particles suitable for use in such method; and equipment suitable for implementing the method.

This invention relates to a system for mitigating the deleterious effect on a gas-detection sensor of exposure to ozone, which system comprises a sensor capable of detecting one or more select gas species, the performance of which sensor is degraded by contact with ozone, and a scrubber capable of absorbing ozone or otherwise converting ozone to one or more other substances so as to mitigate degradation of the sensor's performance; and a method for mitigating such deleterious effect as well.
