Robust system for screening mail for biological agents

Items of mail are rapidly processed in a mail sampling system to determine if the mail is contaminated with a chemical or biological agent. The mail sampling system maintains a negative pressure in a containment chamber and includes a triggering sampler that makes a threshold determination regarding possible contamination, and a detecting sampler that obtains a sample for more detailed analysis in response to a signal from the triggering sampler. A sample of particulates collected from an item of mail is either removed for analysis or analyzed in the system to identify a contaminating agent. Optionally, the system includes an archiving sampler, which archives samples for subsequent processing and analysis, and a decontamination system, which is activated to decontaminate the mail if needed.

Semiconductor processing apparatus with simultaneously movable stages

A method and apparatus provide for simultaneously moving multiple semiconductor wafers in opposite directions while simultaneously performing processing operations on each of the wafers. The semiconductor wafers are orientated in coplanar fashion and are disposed on stages that simultaneously translate in opposite directions to produce a net system momentum of zero. The die of the respective semiconductor wafers are processed in the same spatial sequence with respect to a global alignment feature of the semiconductor wafer. A balance mass is not needed to counteract the motion of a stage because the opposite motions of the respective stages cancel each other.

Remote Monitoring of Pipelines using Wireless Sensor Network

A wireless sensor system is installed inside pipelines using sensors and wireless transceivers that are small, low-cost, and rugged. The objective is monitoring the pipeline and recommending maintenance and repair at specific locations in the pipeline. Maintenance includes detection of leaks and prevention of catastrophic failures as a result of internal corrosion or other damage, such as third party mechanical damage, using multitude of sensors. After establishing the wireless sensor network the network is activated so the sensor can make measurements periodically or continuously using instructions transmitted via the base station. The sensor data from the various sensors are transmitted inside the pipe and extracted to access points in the pipeline to a remote computer that stores the data within the computer memory. The sensed information can be used for monitoring as well as analysis using a recommendation engine to provide maintenance and repair alerts.

Apparatus, systems and methods for detecting and transmitting sensory data over a computer network

A vapor sensing device that is sufficiently small and lightweight to be handheld, and also modular so as to allow the device to be conveniently adapted for use in sensing the presence and concentration of a wide variety of specified vapors. The device provides these benefits using a sensor module that incorporates a sample chamber and a plurality of sensors located on a chip releasably carried within or adjacent to the sample chamber. Optionally, the sensor module can be configured to be releasably plugged into a receptacle formed in the device. Vapors are directed to pass through the sample chamber, whereupon the sensors provide a distinct combination of electrical signals in response to each. The sensors of the sensor module can take the form of chemically sensitive resistors having resistances that vary according to the identity and concentration of an adjacent vapor. These chemically sensitive resistors can each be connected in series with a reference resistor, between a reference voltage and ground, such that an analog signal is established for each chemically sensitive resistor. The resulting analog signals are supplied to an analog-to-digital converter, to produce corresponding digital signals. These digital signals are appropriately analyzed for vapor identification. The device can then subsequently transmit the digital signals over a computer network, such as the Internet, for analysis at a remote location.
