摘要： A method and system for collecting airborne particles and hydrating the collected particles for analysis. The airborne particles, which may be biological contaminants, are collected from a container containing one or more mailpieces. In the collection stage, a dry filter collection assembly is connected to the container and air is drawn out of the container through a dry filter. A hydration solution is then injected into the collection assembly to hydrate the collected particles. Part of the hydration solution containing the collected particles is caused to move out of the collection assembly to a test cartridge for further testing.

摘要： A method and system for isolating, transferring and testing potentially contaminated mail pieces. The mail pieces are encapsulated in a sealed package at one location and transferred to another location for testing. During testing, the sealed package is connected to an air sampling system, which directly draws an air sample from the sealed package. At the end of testing, the air pressure in the sealed package is sufficiently reduced, causing the sealed bag to collapse. A septum or a tube with a self-sealed coupler is provided on the sealed package to allow the air sampling system to draw air out of the sealed package. When the air sampling system is not connected to the sealed package, the septum or the self-sealed coupler prevents the air inside the sealed package from escaping into the environment. It is advantageous to disturb the mail pieces during air sampling.

摘要： A method is provided for identifying mail pieces which may contain a suspicious (biohazardous/chemical agents or hoax materials). The method includes the steps of (i) causing particulate material to collect in a first region of the mail piece; (ii) producing a first content profile indicative of the internal contents of the mail piece; (iii) comparing the first content profile to a predefined baseline profile for determining whether the first content profile indicates the presence of a particulate material in the first region of the mail piece; and out-sorting a mail piece in response to the indicator. To ensure that other mail piece print, or physical characteristics, are not mistakenly identified as particulate material, steps (i)-(iii) may be repeated with certain modifications. These changes are directed to causing particulate material to collect in a second region of the mail piece envelope and comparing a newly developed second content profile with the first content profile to ascertain whether the particulate material is capable of movement, i.e., from the first to the second regions. In yet another embodiment of the inventive method and system, other detection schemes are employed which combine at least two non-specific triggering mechanisms to mitigate the instances of “false positive” indications. That is, by combining at least two such detection schemes, the probability of an accurate/valid assessment is dramatically increased.

摘要： Methods and systems to monitor the operation of ink jet print heads that are easy to implement and inexpensive are provided. The print head is positioned over an array of wires. The array of wires is heated, and the print head is controlled to eject droplets of ink from each nozzle of the print head onto a corresponding wire. Nozzles that are operating properly will eject droplets of ink, which will lower the temperature of the wire, thereby causing a change in resistance of the wire. Nozzles that are not operating properly will not eject droplets of ink, and therefore the resistance of the corresponding wires will remain constant. The resistance of each wire is monitored, and if a change in resistance in a wire is not detected, indicating that the ink droplets were not ejected onto that wire, a signal is generated that indicates a non-operational nozzle.
