A health monitoring car seat assembly for monitoring the health of a child thereon includes a child safety seat that receives a child thereon. A housing is attached to the child safety seat. A sensing unit is mounted on the housing. The sensing unit detects vital signs of a mass in the child safety seat when the mass is a child. The vital signs include body temperature and heart rate. The sensing unit also detects an ambient temperature of air adjacent to the child safety seat. A display is mounted on the child safety seat and is electrically coupled to the sensing unit. The display displays each of the ambient temperature, the temperature of the child, the heart rate of the child and the weight of the child. A power supply is mounted in the housing and electrically coupled to the sensing unit and the display.

A prosthetic socket cooling system and method includes a thermally conductive heat spreader including a curved shaped portion configured to maximize contact with a residual limb of a user. A heat extraction subsystem is coupled through a wall of the prosthetic socket and to the thermally conductive heat spreader and is configured to maintain a desired temperature inside the prosthetic socket.

A cooling garment for use by workers in hot, humid climates comprising: a moisture-wicking under layer; an outer layer with an air permeability less than 200 L/m.sup.2/s when subjected to 125 Pascals of air pressure; at least one air channel formed between the layers and supported in at least some locations by a porous filler material; and an above ambient pressure gas supply attached operably to the inlet of the channel. Also a cooling garment comprising: a moisture-wicking under layer; an outer layer; one large air channel formed between the layers; tacks connecting the outer layer to the moisture-wicking under layer to prevent ballooning; and an above ambient pressure gas supply operably attached to the inlet of the channel.

A patient support structure includes a cushion layer. A microclimate structure is integrated atop the cushion layer. The microclimate structure includes an upper layer having a vapor and liquid permeable therapeutic region, an air permeable middle layer, and a liquid impermeable lower layer. A first plurality of perforations extends through the upper layer of the microclimate structure in a seat section of the microclimate structure. A second plurality of perforations extends through the upper layer of the microclimate structure in a head section of the microclimate structure. When the microclimate structure is in a first position, air is supplied through the first plurality of perforations and the second plurality of perforations. When the microclimate structure is in a second position, air is supplied through the first plurality of perforations and air flow through the second plurality of perforations is limited.

A neck fan is provided and is configured to be worn around a neck of a user. The neck fan includes: an outer shell, disposed away from the neck; an inner shell, connected to the outer shell and disposed near the neck, wherein the inner shell and the outer shell cooperatively define a receiving space. A plurality of air outlets are defined in the inner shell.

A neck fan is provided and is configured to be worn around a neck of a user. The neck fan includes: an outer shell, disposed away from the neck; an inner shell, connected to the outer shell and disposed near the neck, wherein the inner shell and the outer shell cooperatively define a receiving space. A plurality of air outlets are defined in the inner shell.

A neck fan is provided and is configured to be worn around a neck of a user. The neck fan includes: a shell, defining a receiving channel; and two centrifugal fans. One of the two centrifugal fans is disposed at an end of the receiving channel, and another one of the two centrifugal fans is disposed at another end of the receiving channel. Each of the two centrifugal fans includes: a plurality of blades, configured to rotate to intake air from an outside of the centrifugal fan to generate wind; and a vortex tongue structure, including a pressurizing plate and a wind guiding plate connected to the pressurizing plate. The pressurizing plate is a curved wall arranged around ends of some of the plurality of blades, the wind guiding plate protrudes from and is extending away from an outer surface of the pressurizing plate.

A prosthetic socket cooling system and method includes a thermally conductive heat spreader including a curved shaped portion configured to maximize contact with a residual limb of a user. A heat extraction subsystem is coupled through a wall of the prosthetic socket and to the thermally conductive heat spreader and is configured to maintain a desired temperature inside the prosthetic socket.

A neck fan is to be worn around a neck of a user and includes a shell, including an inner shell and an outer shell connected to the inner shell. The inner shell is disposed near the neck, and the outer shell is disposed away from the neck. The outer shell is arranged with a connection post, the inner shell defines a connection hole in which the connection post is inserted for connection; a blocker is arranged and inserted in the connection hole; the connection post and the blocker are inserted into the connection hole from two opposite directions of the connection hole.

A neck fan is configured to be worn around a neck of a user, the neck fan includes: a shell, comprising an inner shell and an outer shell, where the inner shell and the outer shell are connected to each other to form a receiving cavity; the inner shell is disposed near the neck, the outer shell is disposed away from the neck; at least two fan assemblies, received in the receiving cavity. Each of the at least two fan assemblies includes a drive shaft and fan blades mounted on the drive shaft, an end of the drive shaft is fixedly arranged on the inner shell, the drive shaft is extending from the inner shell towards the receiving cavity, and the other end of the drive shaft is a free end spaced apart from the outer shell.
