  • THREE-DIMENSIONAL PRINTER COMPONENTS
    Publication number: 20240189912
    Abstract: The present disclosure provides three-dimensional (3D) printing systems, apparatuses, methods and non-transitory computer readable media for the production of at least one requested 3D object. The 3D printer described herein facilitates operation of a layer dispensing mechanism with high precision albeit operating in an enclosure contaminated by debris, e.g., during the 3D printing. The debris may be a byproduct of the 3D printing.

  • Hand dryer with sanitizing ionization assembly
    Patent number: 9421291
    Abstract: A hand dryer assembly including a blower assembly for generating a moving air stream. The moving air stream passes through an air channel to an air outlet where it exits the hand dryer assembly. An ionization assembly is disposed along the air channel and emits charged ions directly into the moving air stream, sanitizing the hands of the user, the moving air steam, and the ambient air that is entrained into the moving air stream.

  • Systems and methods of air treatment using bipolar ionization
    Patent number: 8564924
    Abstract: A system and method of treating air. Bipolar ionization is delivered to an airflow within a conduit from a tubeless ion generator. The ionized airflow may be delivered to a conditioned airspace by an HVAC system. In alternate applications, the airflow delivers ionized combustion air to an engine. The invention also includes a mounting assembly for positioning one or more ion generators into an airflow.
