Apparel for monitoring optimal body shell temperature during physical activity. The apparel uses thermochromic dyes and thermochromic inks to indicate changes in body shell temperature as physical activity commences and progresses. The thermochromic dyes and inks reveal when the body shell temperature has reached a temperature indicating optimal muscle performance, and inform the wearer of the apparel whether to increase or decrease the intensity of the physical activity to establish or maintain the optimal body shell temperature.

The present invention provides a signal gear for cyclist to give brake and turn signals to other road users while the cyclist has full control of the handle bar and brake. The signal gear of the present invention is preferably a glove with finger portions. Control and activation of the turn and/or brake signals is mainly by using electrical conductive nature of the signal glove as a switch of the signaling component which is either incorporated with the glove or with the vehicle (e.g. bicycle). The signaling component can emit turn/brake light signal or transmit an activation signal to a light emitting device to give turn/brake light signal. The turn and brake light signals are in yellow and red color, respectively.

The technology described herein relates to breathable, vented, and insulating garments. More particularly, the technology described herein relates to articles with a plurality of interconnected chambers that are configured to retain a thermally insulating fill material such as down or synthetic fibers. The plurality of interconnected chambers are formed between at least two layers of material and between a plurality of seams. The plurality of seams are configured to join the at least two layers of material together. In one aspect, each seam of the plurality of seams is angularly oriented with respect to an adjacent or neighboring seam of the plurality of seams. One or more openings or perforations may be formed on one or more seams of the plurality of seams forming the plurality of interconnected chambers. The one or more openings may achieve evaporation of moisture and/or air transfer from an interior environment of the garment to an exterior environment.

The present invention is directed toward an article of apparel effective to regulate the temperature of the wearer. In an embodiment, the article of apparel includes a base textile with a thermal regulation membrane. The thermal regulation membrane contains a plurality of system-reactive components selectively engaged heat and/or moisture. In an embodiment, the printed coating includes a cooling agent, a phase change material, and a heat dissipation material. In operation, the article of apparel is effective to delay/diminish the rise in skin temperature (compared to a garment lacking the membrane), increasing wearer comfort.

An evaporator includes a housing with a first end and a longitudinally opposite second end, a hydrophobic membrane arranged within the housing fluidly coupling the first end of the housing to the second end of the housing, and a hydrophilic surface. The hydrophilic surface is arranged within the housing between the first end and the second end of the housing and is spaced apart from the hydrophobic membrane to draw liquid water away from the hydrophobic hollow fiber membrane. Spacesuits and environmental control methods are also described.

Cooling suit including legs, torso and arms, which includes outwardly opening hose sleeve in the hip area, inwardly branching gas ducts having several outlet openings. A pressurized gas cylinder for carrying along and connecting outlet hose with coupling piece to this hose sleeve, and which comprises a valve and adjusting wheel for the regulated delivery of expanded gas into these gas ducts. The gas ducts in the upper-body have outflow openings in the area of the lower back, hips, neck area, armpits, arm joints, and sleeves. In the lower-body garment, outflow openings are arranged in the knees and the crotch area. This cooling suit is operated with a dry, compressed gas. The gas flowing from the pressure cylinder is expanded, subsequently cools down and then flows through the gas ducts and cools the body. Perspiration is carried away by the permanent gas supply via the breathable fabric of the suit.

A temperature regulation system for regulating the temperature of a portion of a body, in particular of a user's body.

The system comprises one humidity sensor for measuring humidity in the vicinity of the portion of a body, one temperature adjustment element for providing heat to a portion of the body, a memory unit for storing one threshold humidity related value (H.sub.thresh) and one reference user information related values (t.sub.ref, θ.sub.ref), a controlling unit in communication with the humidity sensor, with the memory unit and with the temperature adjustment element, and configured to determine one instant user information related value (t.sub.inst, θ.sub.inst), perform a comparison between one instant user information related value (tin.sub.ct, θ.sub.inst) and one triggering user information related value (t.sub.trig, θ.sub.trig) based on said reference user information related value (t.sub.ref, θ.sub.ref), activate the temperature adjustment element to provide heat to a portion of the body depending on the result of said comparison.

The controlling unit is further configured to receive one instant humidity (H.sub.inst) measured in the vicinity of the portion of the body from the humidity sensor, perform a comparison between said instant humidity related value (H.sub.inst) and one triggering humidity related value (H.sub.trig) based on said threshold humidity related value (H.sub.thresh), and to set the one triggering user information related value (t.sub.trig, θ.sub.trig) to a value lower than said reference user information related value (t.sub.ref, θ.sub.ref) when the instant humidity related value (H.sub.inst) is greater or equal to said threshold humidity related value (H.sub.thresh).

A heated sock to keep the wearer's feet and toes warm, is disclosed. The heated socks comprise a pocket for oxygen-activated chemical heating pouch which generates heat when exposed to air, and distributed to the whole feet from toe to ankle and heel through friction caused by the wearer when walking, jumping or other activities. The heated socks are provided with the extra cushion on the bottom of the feet to aid in comfort for the wearer. The heated socks keep the feet dry from moisture and perspiration.

Bladders/containers designed to hold a meaningful amount of material (in any state: solid, liquid or gas) to conductively absorb heat from the human body. In addition, the material may be consumed by the user wearing the bladder/container, thus providing a source of hydration for the user. The bladders/containers would also enhance impact and/or ballistic protection of the user.

Digital or “smart” contracts execute in a blockchain environment. Any entity (whether public or private) may specify a digital contract via a contract identifier in a blockchain. Because there may be many digital contracts offered as virtual services, the contract identifier uniquely identifies a particular digital contract offered by a virtual machine, vendor or supplier. The blockchain is thus not burdened with the programming code that is required to execute the digital contract. The blockchain need only include or specify the contract identifier (and perhaps one or more contractual parameters), thus greatly simplifying the blockchain and reducing its size (in bytes) and processing requirements.
