A helmet is provided, comprising: a first shell having a convex top; a second shell having a concave bottom; a base having: a convex top affixed to the concave bottom of the shell; a concave bottom secured to the convex top of; and an air flow channel formed in the convex top of the base for guiding air through to an exit in the concave bottom of the base; a power and electronics module secured within a cavity in the first shell, comprising: a power source, comprising: a solar array secured; a battery pack; and a charging module configured to charge the battery pack from current provided by the solar array; and a 5 volt power output connector electrically coupled to the power source and configured for charging a small electronic device; and a heater electrically coupled to the power source.

A personal air filtration system comprising a rigid component, a flexible component, wherein the rigid component and the flexible component combine to cover at least a user's mouth and nostrils and form a seal therearound, an intake port with an inlet filter, an exhaust port, an air mover causing filtered air to enter the intake port and exhaust air to exit the exhaust port, and an app running on a user's smart device, wherein a smart app is configured to control and monitor operation of the system.

A helmet system includes an outer protective shell defining an inner cavity and an inner protective system positioned within the inner cavity. The inner protective system has a padding layer coupled to the outer protective shell. The helmet system also includes a temperature regulation system that has at least one temperature regulation element, a power source configured to provide electrical power to at least one temperature regulation element, and a sensor configured to generate an output signal based on a sensed temperature. The temperature regulation system also has a processor in communication with the sensor and the processor is configured to provide electrical power to at least one temperature regulation element responsive to the output signal exceeding a temperature threshold.

A safety helmet includes an outer shell configured for surrounding a head of a user, and an infrared reflective layer disposed in an interior of the outer shell. The infrared reflective layer is configured for reflecting at a least a portion of incident infrared radiation transmitted through the outer shell. The infrared reflective layer has infrared reflectivity of at least 40%. The safety helmet further may have an evaporative cooling pad positioned within a cavity defined by the inner surface of the outer shell. A method of manufacturing a safety helmet is also disclosed.

A personal protection system that includes a headband (52) to which a face shield (38) is mounted. A cooling strip (120) is mounted to the headband. The cooling strip includes at least one thermoelectric cooling module (150). A draw strip (128) formed from a flexible thermally conductive material is also part of the cooling strip. The draw strip is bonded to the heat absorbing surface (152) of the thermoelectric cooling module and extends outwardly from the module. A biasing assembly (134, 186) urges the portions of the draw strip spaced from the thermoelectric cooling module against the skin of the individual wearing the personal protection system.

A protective member such as a helmet includes an outer layer and an inner layer interconnected by multiple connectors, such as extension springs, under tension along their longitudinal axis. The connectors absorb energy from an impact force by resisting further tension along their longitudinal axis and allow the outer layer and inner layer to move relative to each other. In the helmet application, the head of a user experiences less impact force, reduced change in momentum or position of the head and neck, reduced head and neck loads and reduced amounts of linear and rotational acceleration. The protective member can be used in numerous applications and environments, including for participants in sports, in applications including bumpers, passenger cabins, car seats and beds.

A magnetic quick connect for a fluid delivery system includes a male coupling member and a female coupling member. The male coupling member defines a first outer fluid communication path and includes a first magnetic material. A first inner member is disposed within the first outer fluid communication path and defines a first inner communication path. The female coupling member defines a second outer fluid communication path and includes a second magnetic material. A second inner member is disposed within the second outer fluid communication path and defines a second inner communication path. The male and female coupling members are detachably held together by an attractive force between the first and second magnetic materials such that the first and second outer communication paths are held in fluid communication, and the first and second inner communication paths are held in fluid communication.

A modular helmet is described herein. The module helmet includes an inner shell adapted to be positioned onto a user's head and an outer shell coupled to the inner shell. The outer shell is spaced a distance radially outward from the inner shell to define a climatic zone between the inner shell and the outer shell. A cooling assembly is positioned within the climatic zone between the inner shell and the outer shell. The cooling assembly includes a plurality of cooling packets that are coupled to the outer shell.
