VisualSniffer, HealthWatch, and BVTech Plasmid are utilities that we initially developed for our consulting works. Because all these tools are very useful, we made them to be free for everyone.

VisualSniffer VisualSniffer is a powerful packet capture tool and protocol analyzer (sometime called packet sniffer or ip sniffer) for Windows system. VisualSniffer can be used by LAN administrators, and security professionals for network fault analysis, performance analysis, intrusion detection, and network traffic logging. It can also be used by networkprogrammers, or others to get a full picture of the network traffic.

BVTech Plasmid is a plasmid drawing software. You can use it to draw circle or linear plasmid with double strands or single strand. You can label the plasmid with genes and restriction sites in different colors, text, and styles.

HealthWatch is a health monitoring application for both family and health professionals in clinical and research settings. HealthWatch can calculate growth percentiles for infants, children and adolescents (2 to 20 years); blood pressure percentiles for children (under 17); and BMI for children and adults. This program uses data of child growth chart and baby growth chart from CDC to calculate growth percentiles, and the "Blood Pressure Tables for Children and Adolescents" from National Heart, Lung, and Blood Institute to calculate Blood pressure percentiles for children. Unlike other BMI calculators, a graph is provided for you to chart your health statistics over time. HealthWatch can also evaluate underweight and overweight, identify metabolic syndrome and calculate risk for having a heart attack using the algorithms from Adult Treatment Panel III.
