Title: The Innovations of Daniel C Bjorkquist

Introduction

Daniel C Bjorkquist is an accomplished inventor based in Maplewood, MN (US). He holds a total of four patents, showcasing his expertise in the field of aerosol science and respiratory technology. His innovative contributions have significantly advanced the understanding and application of particle detection systems.

Latest Patents

One of his latest patents is focused on in situ respirator fit testing. This system includes a first and second condensation particle counter, each equipped with an inlet port, a growth column, and an optical element for counting particles detected at the respective inlet ports. The counters are designed to include a wick that is wetted by water. A differential pressure sensor is coupled to both inlet ports and is configured to provide a pressure signal. A processor, connected to memory, receives the first and second signals along with the pressure signal, generating an output that correlates the ratio of the first and second signals with the pressure signal. The entire system is housed in a dedicated enclosure that accommodates all components.

Another significant patent addresses the false count performance of condensation particle counters. This invention includes methods and systems aimed at reducing false-particle counts in a water-based condensation particle counter (CPC). One embodiment involves delivering water into multiple wicks that transport separate portions of an aerosol sample flow. The wicks extend from a wick stand to a flow joiner, where particles from the separate portions are combined into a single aerosol stream before entering the particle detection chamber. The system also includes mechanisms for sensing and managing excess water delivered to the wicks.
