Patents' search is increasingly critical for a company's technological advancement and sustainable marketing strategy. When most innovative designs are created collaboratively by a diverse team of researchers and technologists, patent knowledge management becomes time consuming with repeated efforts creating additional task conflicts. This research develops an intelligent recommendation methodology and system to enable timely and effective patent search prior, during, and after design collaboration to prevent potential infringement of existing intellectual property rights (IPR) and to secure new IPR for market advantage. The research develops an algorithm to dynamically search related patents in global patent databases. The system clusters users with similar patent search behaviors and, subsequently, infers new patent recommendations based on inter-cluster group member behaviors and characteristics. First, the methodology evaluates the filtered information obtained from collaborative patent searches. Second, the system clusters existing users and identifies users' neighbors based on the collaborative filtering algorithm. Using the clusters of users and their behaviors, the system recommends related patents. When collaborative design teams are planning R&D policies or searching patents and prior art claims to create new IP and prevent or settles IP legal disputes, the intelligent recommendation system identifies and recommends patents with greater efficiency and accuracy than previous systems and methods described in the literature.

This paper defines and integrates after-sales service processes for an industrial manufacturer of power transformers. High priced and highly customized electricity transformers are sold to power generating companies that hold high service expectations througout the product life cycle. The e-integration of business processes for prior sales, ongoing sales, and after sales services are critically important for the transformer manufactuer to overcome well know problems with traditional paper based systems. This research analyses the business processes for transformer sales services and then integrates the best practices into a sales service platform. The study studies the current practices (as-is models) of customer services offered by the company. After identifying problems such as service delays, cost inefficiencies, and inappropriate responses to customers requests and complaints, the improved (to-be) process models are built, analyzed, and structured using the enterprise systems tool INCOME4. The Internet based system incorporating the to-be service processes is implemented to improve customer response as well as enhance the efficiency and effectiveness of after sales services.

Electrowetting on dielectric (EWOD) moving fluid by surface tension effects offers some advantages, including simplicity of fabrication, control of minute volumes, rapid mixing, low cost and others. This work presents a numerical model using a commercial software, CFD-ACE+, and an EWOD system including a microfluidic device, a microprocessor, electric circuits, a LCD module, a keypad, a power supply and a power amplifier. The EWOD model based on a reduced form of the mass conservation and momentum equations is adopted to simulate the fluid dynamics of the droplets. The EWOD device consists of the 2 x 2 mm bottom electrodes (Au/Cr), a dielectric layer of 3,000 angstrom nitride, 500 angstrom Teflon and a piece of indium tin oxide (ITO)-coated glass as the top electrode. The complete EWOD phenomenon is elucidated by comparing simulation with the experimental data on droplet transportation, cutting and creation. In transportation testing, the speed of the droplet is 6 mm/s at 40 V-dc. In addition, the droplet division process takes 0.12 s at 60 V-dc in the current case. Finally, a 347 nl droplet is successfully created from an on-chip reservoir at 60 V-dc.
