A monitoring system and method for detecting environmental conditions is provided, the monitoring system including a sensing unit including a plurality of sensors for obtaining data related to environmental conditions, a controller interfaced with the sensing unit for receiving and encoding the data related to environmental conditions into a predetermined format using a base64 encoding scheme, and a communication device for receiving the data in the predetermined format from the controller, forming an e-mail message (which can be further encoded) including instructions on how to decode the email message and transmitting the e-mail message including the data in the predetermined format to at least one predetermined recipient.

System and method for monitoring environmental conditions

A method and apparatus for evaluating a bioaerosol sample is provided which includes detecting frequency and/or time resolution factors that allow discriminate between a plurality of signals emitted by the bioaerosol to selectively detect biological materials contained in the bioaerosol sample from materials of non-biological origin and potentially associated with a pathogenic bioaerosol.

Method and apparatus for detection of bioaerosols

A system () and method for detecting contaminants in parcels or other mailings (). The contaminants, either genuine or hoax, are detected using the system () that includes a jogger () that shakes the parcels or other mailings (). The system () further comprises a particle sampler () that analyzes the air flow created over the parcels () while the parcels are shaken. The system () and method preferable includes a parcel opening cutter () and a ram () for compressing during the shaking of the parcels. The air flow is sampled in order to detect whether or not a plurality of opened parcels is suspected of including contaminants such as biological threat material.

Method and apparatus to detect genuine or hoax contaminants

A system and method (FIG.) for automated handling and identification of parcels sorted by an automated high-speed mail sorting apparatus that identifies parcels that contain hoax or biological threat material comprising an opener () and a particle sampler () wherein said sampler analyzes air flow created as the parcels are compressed by pinch rollers ().

Apparatus and method for automated parcel screening

A method and apparatus for particle collection () that is characterized by co-aerosolizing fluids () into an air stream () containing the particles to be analyzed to significantly enhance their collection and identification efficiency is provided.

Method and apparatus for enhanced particle collection efficiency

A hand held, self-contained, automatic, low power and rapid sensor platform for detecting and quantifying a plurality of analytes. A sample solution potentially containing an unknown amount of an analyte is passed through an affinity column which contains antibodies to which the analyte binds thereby extracting the analyte. The affinity column is then rinsed to remove any other chemicals that may fluoresce. The rinsed affinity column is then eluted with a known volume of elution fluid causing the analyte to release from the antibody and dissolve in the fluid (eluant). The eluant is then placed in the quartz cuvette of a fluorometer. The analyte suspended in the eluant fluoresces at a waveband which is different than that of the light source that excites it. The amount of fluorescence is measured and the level of analyte determined. The rinsing and elution fluids, and/or the affinity column can be placed in a module for easy insertion and removal from the sensor when depleted or when the sensor is to be used against a different analyte.

Miniature immuno-optical rapid analyte sensor platform

The invention comprises a vessel for solid phase micro-extraction chemical sampling. The vessel includes a container having an open end and a cap used to close the open end. The cap has a holder to hold a solid phase coated fiber within an interior of the container. There also is an inlet at a first location of the vessel and an outlet at a second location of the vessel. The inlet and the outlet are adapted to fill the vessel with a material to be exposed to the solid phase coated fiber. The vessel also includes a diffuser plate attached to the container. The plate is adapted to reduce fluid forces exerted on the solid phase coated fiber as material flows from the inlet to the outlet. The purpose of the diffuser plate is both to assure that forces are reduced and to provide laminar flow to assure rapid and complete exchange of the fluid in the vessel.

Reservoir for use with sampling interface for a vehicle

A field portable mass spectrometer system comprising a sample collector and a sample transporter. The sample transporter interfaces with the sample collector to receive sample deposits thereon. The system further comprises a time of flight (TOF) mass spectrometer. The time of flight mass spectrometer has a sealable opening that receives the sample transported via the sample transporter in an extraction region of the mass spectrometer. The system further comprises a control unit that processes a time series output by the mass spectrometer for a received sample and identifies one or more agents contained in the sample.

Portable time-of-flight mass spectrometer system

The invention comprises a material sampling interface that includes one or more inlet manifolds and one or more outlet manifolds and piping running to and from the manifolds. There are rungs connecting the inlet manifold to the outlet manifold. In addition, a bypass rung is positioned between the inlet manifold and the outlet manifold, with a bypass valve positioned on the bypass. Each of the rungs has piping connected to the inlet and outlet manifolds and a removable reservoir connected to the piping. The reservoir includes an internal removable sampler adapted to sample the material. There is an inlet valve connected to the piping between the reservoir and the inlet manifold and an outlet valve connected to the piping between the reservoir and the outlet manifold. The invention is capable of sampling any flowable material including fluids, gases, particles, etc.

Sampling interface for a vehicle

An integrated fluidics system for simplified analysis of aerosolize biological particles has a unitary self-contained ticket provided with a sample fluid reservoir, an array of particle-detection strips, which is located adjacent to the sample reservoir, and, optionally, a cleaning fluid reservoir and an impinging nozzle. The fluidics system is, thus, configured to substantially minimize the fluid paths between the components of the system.
