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.

A display apparatus creates a modifiable three-dimensional image. The apparatus includes a plurality of non-planar pixel units arranged substantially on a plane. Each of the non-planar pixel units has a visual impact that is a function of direction. An electronic device is provided for modifying said functions to change the three-dimensional image.

A system for determining whether a mail piece has been opened including mail pieces that have the ability indicate a previously opened and never opened state, such as with a state change element, an interrogator unit, such as an RFID reader, for receiving state information, and a data center that receives the state information from the interrogator unit. Also, a method for determining whether a mail piece has been opened including receiving mail pieces at a recipient location, receiving at an interrogator unit, such as an RFID reader, state information from the mail pieces, and transmitting the state information from the interrogator unit to a data center. In either the system or method, each mail piece may have an RFID tag that communicates with the state change element and transmits the state information to the RFID reader. Bar code or other technologies may be substituted for RFID technology.

A method and system for encapsulating mail containers delivered to a building so as to prevent possible contaminants in the mail containers from contaminating the building. An opening is provided on a building wall that substantially separates indoor air circulation from the outdoor air for receiving the mail containers. A plastic tube having a closed end and an open end is used to encapsulate the mail containers. The open end is securely attached to the opening in the wall for receiving the mail containers into the tube, while preventing air circulation outside the building from entering the opening. A sealing device is used to seal the plastic tube for keeping the mail containers in separate sealed sections. A severing device is used to separate the sealed sections in the encapsulated packages so that the encapsulated packages can be tested for the possible contaminants.
摘要:
A system and method for detecting a mailpiece contaminated by hazardous agents/materials including at least one contaminant sensor for detecting the presence of a hazardous agent/material and a Radio Frequency Identification (RFID) device in communication with the contaminant sensor. The contaminant sensor issues an alert signal to the RDIF device indicating that a hazardous agent/material has been sensed. The RFID device communicates a signal concerning the current status of the RFID device i.e., indicative of whether the RFID device and, consequently, the mailpiece has been in, or proximal to, the hazardous agent/material.

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:
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.

A method for detecting whether perforations are present on the edge of an image of a form, such as a check, includes obtaining a bitmap of the image, identifying a selected portion of the bitmap that corresponds to at least the edge and that includes a matrix of a plurality of rows and columns of brightness values, and selecting a particular one of the rows of brightness values. The method further includes performing a Fourier transform of the brightness values included in the particular selected row to generate a Fourier transform output, and determining whether a series of perforations is present based on the Fourier transform output. The method may also include steps wherein the brightness values are low pass filtered and wherein the values in the selected row are high pass filtered prior to the step of performing a Fourier transform
摘要:
A method for forwarding an e-mail message from a disfavored e-mail address to a forwarding e-mail address via a remote e-mail forwarding computer having a unique e-mail address. An e-mail message is sent from a user to the remote e-mail forwarding computer. The remote e-mail forwarding computer parses the intended e-mail address from the e-mail message to determine if there is a disfavored e-mail address associated with the intended e-mail address. The e-mail message is sent from the remote computer to a computer associated with at least one forwarding address if there is determined at least one disfavored e-mail address is associated with the intended e-mail address. If there is not a determined forwarding e-mail address than the remote computer stores at least the disfavored e-mail in archival for forwarding in the event a forwarding address is subsequently stored in the remote computer which is associated with the disfavored e-mail address.
摘要:
A method and system for reading various codes such as codes imprinted on an item includes a first and a second code reader each scan the code on the item to read the code. The data obtained by the first and the second code reader is merged to reconstruct the code on said item. The position of the one or more of the code readers may be adjusted such that the maximum reading efficiency of said code by each code reader occurs at different points of the scanned code. This helps to facilitate merging the data obtained by the first and the second code reader to reconstruct the code on the item. By adjusting the position of one or more of the code readers, degradation of the reading of the item code due, for example, to beat frequencies occurs at different points in the code for each code reader. The method and system may be employed in various applications such as with sortation systems and other paper handling equipment. The method and system may be employed with different types of codes including various forms of bar codes. The item may have single or plural codes, which may be the same or different type codes.
