Fast Signal Convolution Methods
These signal convolution algorithms were originally developed to perform real-time electron beam proximity effect correction in electron beam writing equipment. In general these convolution techniques are useful anywhere a large data array must be convolved with another static data array. Typical convolution algorithms require on the order of N(logN) operations. These require on the order of N operations, a significant improvement for large data arrays. Large convolution calculations are frequently used in lithography modeling, and hence optical proximity correction. Large convolution calculations are also encountered in the back-projection algorithms of image reconstruction in such diverse fields as seismic imaging for oil and gas exploration, computer tomography for medical imaging, and synthetic aperture radar processing.

Nanoimprint Equipment Technology
The current photo-lithography technology encounters a physical problem in optical imaging, and the fabrication difficulty and costs of fabrication equipment are also greatly increased. Although a next-generation lithography technology has been proposed, it still has problems of high equipment costs and low yields. Nanoimprint that could break through the limit of the conventional lithography technology has the features of simple process, low cost, nano-patterning capability and high throughput. It is the starting technology for nano-fabrication technology.

Video Motion Anomaly Detection
Our patented Video Motion Anomaly Detection (VMAD) intelligent CCTV system uses a unique image processing technique designed to improve the efficiency of closed-circuit television (CCTV) by enabling it to "think." The intelligent CCTV system employs a self-learning alerting mechanism to automatically detect abnormal behavior. Can increase effectiveness of monitoring staff and reduce cost of investment in the system. Easy to use. Software product available for assessment.

Coated plastic packaging film with low vapor transmission
Avery Dennison Corporation has developed a multilayer plastic film that meets the specifications required for flexible food packaging. Of greatest importance are optical transparency and a moisture vapor transmission rate (MVTR) less than 0.2 g/m2 day at thickness well below that available in comparable films (e.g., PCTFE). This low MVTR is combined with a low oxygen transmission rate (OTR < 2 cc/m2 day), at 35C and 90% RH, providing a state-of-the-art combination of barrier properties in an organic film. Extensive development and testing.

Set-top board for video-on-demand service and computer system
A set top board that is mounted within a personal computer in the form of a card (such as a video card and a communications card), includes: a networking part for communicating with a service provider of the VOD service system; an interface for interfacing with the CPU of the personal computer so that the set-top board can be controlled by control signals of the personal computer; a decoder for decoding compressed MPEG image data, and a video processor for processing and outputting data corresponding to the compressed MPEG image data programs as still images on a monitor of the personal computer.

Apparatus for biological remediation of vaporous pollutants
This invention relates to a process for remediating vaporous pollutants which comprises passing a vaporous stream containing one or more of pollutants through a bioreactor, the bioreactor comprising a plurality of biologically active bodies, the biologically active body comprising a macroporous substrate and one or more of microorganisms capable of remediating one or more of said pollutants, wherein the substrate is fabricated from a decomposition-resistant material. The present invention further provides an apparatus for this process.

Method and apparatus for predicting the efficacy of cardioversion
This technology offers a quick, inexpensive, and consistent method for determining the effectiveness of cardioversion in atrial fibrillation patients, and offers physicians the first tool to differentiate reliably between patients who will successfully cardiovert and those who will not. Atrial fibrillation is a disorder found in about 2 million Americans. In it the heart's two small upper chambers (the atria) quiver instead of beating effectively. Blood isn't pumped completely out of them, so it may pool and clot. If a piece of a blood clot in the atria leaves the heart and becomes lodged in an artery in the brain, a stroke results. About 15 percent of strokes occur in people with atrial fibrillation. Cardioversion returns AF to a normal heart rhythm through either an electric shock or drugs. Cardioversion does not work for all patients. At present, no method or system exists that can readily predict the efficacy of any process for enabling a patient's heart to revert from atrial fibrillation to a normal sinus rhythm. The normal process of choice for personnel making such a diagnosis remains the classical analysis of raw data information, as from an EKG over time, in light of experience or a priori knowledge in the field. It is on this basis that a physician tries to predict whether cardioversion or other modality is appropriate to reverting a heart to normal sinus rhythm.

Base-catalyzed synthesis of 1-aryl-4-(aryl ethyl)piperazines from aromatic olefins and 1-arylpiperazines
A process for preparing a 1-aryl-4-(arylethyl) piperazine of the formula (I)by reacting a 1-arylpiperazine of the formula (II)with an aromatic olefin of the formula (III)in an inert solvent in the presence of at least one basic catalyst, where in the formulae (I) to (III)Ar and Ar' independently of one another are an aryl radical, selected from the group of the fused and unfused C6-C22-aromatics and the fused or unfused C5-C22-heteroaromatics which have at least one nitrogen, oxygen or sulfur atom in the ring; andR1 and R2 independently of one another are a hydrogen atom, a C1-C8-alkyl radical or an aryl radical.

Environmentally safe process to remove corrosive by-products from circuit assemblies
Millions of semiconductor devices, circuit boards, and assemblies are processed each year using a variety of automated soldering processes. This novel post-processing and washing process has been developed to remove acids and heavy metals (preventing corrosion) and preclude the use of unfriendly halogenated cleaning agents. The new technology utilizes a combination of aqueous sprays to release and dissolve flux and metal contaminants. The process is applicable to electronic PC boards, devices, and metal parts. Proven in a laboratory and in pilot scale processes.

Wireless patient monitoring based on personal area networks
The Wireless Patient Monitor based on Personal Area Networks aims to improve the challenges in surgical theatres to mobilize patients (in the pre and post operation process) whilst providing real-time patient monitoring during the whole surgical, recovery and post-operation processes. It combines four bio-signal sensors for ECG, pulse oximetry, blood pressure, and breath monitor. The key benefit of the patient monitor is that it can extend the patient monitoring to almost-anywhere provided that it can integrate with any wired or wireless network (Ethernet, ADSL, Wi-Fi, WiMax and Bluetooth) and, also, it can even deploy a mobile channel such as UMTS, GPRS and UMTS to connect to the hospital systems and clinical monitors. Development includes market research, potential applications, and high-level system designs.
