A barrier system, device, and method protects medical professionals and patients from exposure to contaminants and bodily fluids is provided. The system includes a head unit shaped to be worn over the head of the wearer; a hood positioned over the head unit; one or more sensors configured to produce one or more sensor-output signals; and a controller connected to the one or more sensors and configured to produce one or more controller-output signals based on the one or more sensor-output signals. Further, a device inside a barrier system is controlled by (a) sensing one or more characteristics; (b) producing one or more sensor signals based on the sensed one or more characteristics; (c) converting and/or processing the one or more sensor signals to produce one or more controller-output signals; and (d) controlling the device based on the one or more controller-output signals.

A head-mounted heat dissipation device includes a fan assembly and a wearing assembly. The wearing assembly is connected to the fan assembly to fix the fan assembly onto a head of a user. The fan assembly includes a casing and fans arranged in the casing. Air inlets and air outlets are defined in the casing. The air outlets are located on an inner side of the bottom surface of the casing, so that the air from the air outlets can be blown to the user's face. In addition, air guide strips are arranged side by side on a side of the air outlet within the casing for concealing the operation of the fans.

Personal wearable comfort device that distributes fresh air around the users waist and core to help cool via convective and evaporative cooling. The system includes an air distribution belt which houses a fan assembly source for generating air movement and a breathable channel with a relatively air impermeable wrap for directing air movement. The fan assembly source for generating air movement is removable from the belt and consists of a small impeller blower, rechargeable battery, printed circuit board to drive user interface with power on/off and level selections. The breathable channel for air distribution is built using a highly breathable material that is wrapped with one or more materials designed to maintain airflow throughout the interior of the belt and deliver a level of comfort to the user. There are holes/pores introduced to this wrap material to direct the airflow out of the belt and across the ideal regions of the user's body for optimized distribution and thermal cooling performance. This breathable channel for air distribution is adjustable, washable, and customizable to the user.

A garment in one aspect of the present disclosure includes an outer fabric and a lining fabric. The outer fabric forms a front body part and a back body part. The front body part includes a first opening to be situated in a center portion of the front body part in a width direction of the garment when the garment is worn over a wearer. The first opening extends in a length direction of the garment. The lining fabric is attached to the outer fabric so as to form an internal space between the lining fabric and the outer fabric. The internal space is formed (i) to accommodate a fan in the internal space and (ii) to let an airflow generated by the fan pass through the internal space.

An active deformable semi-rigid element is combined with a garment and power source to create a pumping action to create a cooling flow of air across a wearer's body.

To pump-condition a garment that covers at least a portion of an individual, at least one fluid-circulating vent panel circulates a fluid adjacent the garment in an effort to condition the individual. A pump provides a motive force to circulate the circulating fluid through each vent panel, and a conduit is routed within the garment and couples the pump and each vent panel. A controller controls the pump to provide the motive force, and a power source provides power to operate the pump and the controller. The pump may be an ultrasonic piezoelectric pump.

A voltage control device in one aspect of the present disclosure includes an appliance connector, a voltage output circuit, a manual switch, and a controller. The voltage output circuit outputs an operating voltage based on a direct voltage received from a direct-current power source. In response to a first electric appliance being connected to the appliance connector, the controller controls the voltage output circuit so as to fix the operating voltage. In response to a second electric appliance being connected to the appliance connector, the controller controls the voltage output circuit so as to vary the operating voltage in accordance with a manual operation applied to the manual switch.

A fan device that can be attached to a garment body includes a fan, a drive, an operation interface, and a controller. The drive rotates the fan. The operation interface is for a user to switch drive status of the drive. The controller switches the drive status of the drive based on operation on the operation interface by the user. The operation interface includes a first switch and a second switch. The first switch is for switching an air volume of the fan between air volumes of multiple modes. The second switch is for switching a mode to a first mode in which the air volume of the fan is a first air volume which is larger than air volumes that are switched by the first switch.

A garment, to which a blower device is detachably attachable, includes a main body and a heat insulation material. The main body includes at least an outer fabric having an attachment hole through which the blower device can be partially inserted. The main body is configured to cover at least a portion of a body of a wearer. The heat insulation material is attached to the main body at least on an inner side of the outer fabric. The heat insulation material is configured to cover at least a portion of the body. The garment is configured such that the heat insulation material is detachable from the main body.

A ventilating visor is adapted to be worn by a health care provider, who is also wearing a face mask with eyeglasses and/or a face shield. The ventilating visor comprises a visor band and a visor extension. The two ends of the visor band are connected by an adjustable visor strap which secures the ventilating visor on the wearer's forehead. The visor extension supports one or more fans, which direct ambient air downward into the mask, either directly or through tubing. The air pressure on the upper side of the mask diverts the wearer's respiration downward away from the wearer's eyeglasses and/or face shield.
