Abstract: Various devices, systems, and methods are described herein that provide bi-directional, and even multi-directional airflow within fan systems. These fan systems can be utilized by devices such as datacenter switches to change from one direction of airflow (such as port side inlet) to another direction (such as port side exhaust). This can be done manually by having a multi-directional fan housed within an enclosure that provides access through a hatch door. The multi-directional fan can be removed and reoriented to a second direction, thus providing airflow with the same quality and pressure in multiple directions. Fan changes can also be automated through one or more interlocking rotational gears coupled to the fans within a housing, such that rotating one gear will rotate each of the fans within the housing, thus changing the direction of the airflow. By doing this, only one fan is needed to provide airflow in multiple directions.

Abstract: A fan having a base, a plate operatively attached to the base, a fan head housing, and a support arm is disclosed. The plate oscillates relative to the base by an oscillating mechanism. The fan head housing includes a blower assembly with a motor that rotates a blade to produce an air stream. The support arm has a first end pivotally attached to the fan head housing and a second end fixedly attached to the plate. The fan head housing is cantilevered by the support arm. This fan configuration allows for improved airflow direction, enhanced portability and reduced noise.

Abstract: A personal entertainment respiratory apparatus provides air to a user to provide a fully immersive entertainment experience. The personal entertainment system may comprise a flow generator for providing the flow of air. A personal spatial respiratory interface may be coupled to the flow generator. The personal spatial respiratory interface may comprise an outlet for the flow generator. The personal spatial respiratory interface may further be configured to direct the flow of air within an ambient breathing proximity of a user. The personal entertainment respiratory apparatus may further comprise a controller and a sensory particle dispenser. The controller and sensory particle dispenser may be configured to selectively activate release of a sensory particle from the dispenser into the directed flow of air in response to an entertainment triggering signal.

Abstract: A high-speed booster fan module is provided, including an air duct, and an air inlet and an air outlet which are communicated to the air duct. In the present disclosure, the air flow achieves boosting and speeding up under cooperation between the air-driving fan blade group and the boosting mechanism; the air flow is collectively gathered by guidance of the flow guide member, thereby effectively improving the utilization rate of the air flow; and finally, the air flow is blown outwards after being secondarily boosted through the rectifying and boosting hood and subjected to turbulence removal, so that a wind speed and an air supply distance are greatly increased, an effect of silence and noise reduction is achieved.
