Latest Patents

One of his latest patents is an in-line silencer for clean room breathing apparatus. This invention reduces noise transmitted to a user from an attached air blower. The clean room breathing apparatus includes a headgear assembly worn by the user and an air blower that supplies or exhausts air through a connecting air hose. The in-line silencer is installed in the air duct between the air blower and the headgear assembly. It features a shell housing with couplings at opposite ends for easy installation. Inside the shell housing, sound-absorbing material is utilized to absorb sound energy from the air flowing through the silencer.

Another significant patent is a method and device for quantifying particles on a surface. This device includes a scanner that interfaces with the sample surface and is connected to a tube with two canals. One canal supplies air from the particle counter to dislodge particles, while the other returns air with the particles to the counter for counting. After counting, the particles are filtered out, and the air is recycled for additional counting. The method involves passing the scanner over the sample surface for predetermined periods to collect and compute the average number of particles per unit area.
