With two patents to his name, Edwards is focused on enhancing safety and efficiency in powered respirators, making significant strides in respiratory health and safety.

Latest Patents

David B Edwards holds two notable patents, both centered around powered respirators. The first patent introduces a device sensitive to the pressure within the respirator, particularly around the user's face. It is designed to emit a warning when the pressure falls below a predetermined threshold. This innovative device utilizes a flexible diaphragm exposed to sensed and atmospheric pressures, along with an infrared emitter and receiver that gauged flexural positions of the diaphragm. Once the receiver detects a critical energy level signifying low pressure, it activates an alarm to alert the user.

The second patent showcases a powered respirator that consists of a motor-driven fan unit. This unit draws air through a pre-filter before delivering it to a facepiece. Importantly, the operation of the fan is controlled by a differential pressure sensor, which adjusts the airflow based on breathing demand. In this design, the diaphragm is shielded from unfiltered air, preventing potential contaminants from reaching the user's face. An alternative design allows for the fan to be positioned upstream of the filter, ensuring contaminants are effectively filtered before air delivery.
