The Virus Cleaner is a system that can clean 95% of virus contaminated air using bleach water at an air flow of 20m/s. It was developed in 2003 during the SARS outbreak and was funded by a CERG grant. The system was tested in the Prince of Wales Hospital in 2004.The Virus Cleaner is ideal in clinics.....

Patients with patellofemoral pain often use knee support braces or sleeves to reduce the friction of knee joints. However, the knee support braces or sleeves may result in reduction in power generation at the joints and limit active flexion. To address the problem, the inventors developed a superela.....
