Latest Patents

Harrsen’s most recent patents include:

1. **Method and Device for Optically Counting Small Particles**: This invention involves a sophisticated mechanism whereby small particles, such as seeds and fertilizers, are counted optically. As particles travel past a test field, they interrupt a beam of light connecting a light emitter and a light detector. To enhance counting accuracy, multiple points where the light beam is interrupted are detected sequentially, forming an optical grid. Information from various scanning cycles is compared to derive counting signals corresponding to the number of particles moving through.

2. **Method of and Device for Acoustically Counting Particles**: This invention focuses on a method of counting agricultural particles acoustically. When particles are conveyed against an impact plate, they set it oscillating, generating electric signals that help ascertain their number. To achieve precise counting, a characteristic oscillation amplitude from individual impacts is stored and compared with the actual oscillation amplitude. Depending on this comparison, the system determines how many particles have struck the plate.
