  • Patent number: 11819604
    Abstract: A breathing airflow detecting device for a nebulizing device is disclosed. The breathing airflow detecting device includes a case, wherein a light switching module and a light blocking element are arranged in the case. The light blocking element is arranged between optical routes of a light emitting element and a light receiving element. When airflow from an inlet blows and swings the light blocking element, the light blocking element blocks light or passes light to the light receiving element. When the light receiving element detects the variation of light, the light receiving element emits a signal from the output port of the light switching module to drive or stop driving a nebulizing device. As a result, when a patient breathes, the nebulizing device is driven such that the volume of the nebulized medicine is accurately inhaled into the patient's lungs.

  • Publication number: 20220199547
    Abstract: Fan-out wafer-level packaging (FOWLP) integrated circuits (ICs) employing electro-magnetic (EM) interference (EMI) shield structure in fan out area for EMI shielding, and related fabricating methods are disclosed. The IC includes a semiconductor die (“IC die”) that is bonded to the reconstituted carrier wafer such that a fan-out area is provided between adjacent IC dies to provide area for fan-out interconnects to provide additional die interconnections to the IC die. In exemplary aspects, the IC includes an EMI shield that includes vias formed in an un-used area in fan-out area adjacent to the IC die electrically that are otherwise unused for input/output (I/O) signal interconnects for coupling I/O signals to the IC die. The EMI shield is electrically coupled to a ground node of the IC die to provide an effective EMI shield to block or attenuate unwanted EM noise propagated from the IC die outside the IC.
