摘要： An ultrasonic pump includes a mechanical layer with at least one membrane; and an acoustic channel. A portion of the at least one membrane comprises at least a part of the acoustic channel so that a movement of the membrane changes the dimension of the acoustic channel. The membrane is configured to oscillate at ultrasonic frequencies and generate at least one audio signal.

摘要： A blower configured to be positioned in confined spaces and to provide ventilation of a fluid, such as temperature controlled air, is disclosed. In various embodiments, the blower is configured to have a reduced axial thickness, which can be desired in such confined spaces. In some embodiments, the blower has an integral filter, a wire channel for the routing of one or more wires, and/or an exposed backplate. In some embodiments, the blower has a snap-fit circuit board, containment system for mounting the motor, one or more vanes for directing fluid flow, shrouded impeller, and/or integrated connector.

摘要： The present invention relates to an overboil protection device removably couplable to a cooking utensil. The overboil protection device includes blower fan(s) configured to provide forced air to food items placed on a cooking surface of the cooking utensil, an electrical power source providing electric power to the blower fan(s), a clip element or an attachment element that couples the overboil protection device to the cooking handle of the cooking utensil, a mount element positioned between the blower fan(s) and the clip element. The overboiling protection device prevents food item from being overboiled and reaching overspill stage. The overboiling protection device does not make any physical contact with the food item placed in the cooking utensil.

摘要： A fan drip-proof structure of an embodiment includes a housing, one or more open-close members, and a regulation member. The housing accommodates a fan. The one or more open-close members open and close a vent port formed on the housing in response to a wind force of an air flow of the fan. The regulation member regulates an open degree of the vent port by the open-close member.
