An article of apparel and method of making the article of apparel for a wearer is disclosed herein. In at least one embodiment, the article of apparel comprises a fabric defining a first, inner surface facing the wearer, and a second, outer surface opposite the first surface. A plurality of compression areas are formed along the inner fabric surface, each compression area comprising compressed yarns. A sealing agent effective to reduce the air permeability of the fabric is applied to each compression area. The sealing agent secures the yarns in a compressed state.

A cryotherapy garment includes a number of receptacles that receive at least one pack of cold-store material. Each of the receptacles is formed by a closed fabric fold in the garment. Each of the receptacles has an opening for insertion of the pack of cold-store material. Each receptacle receives a respective pack, which is made of a semi-rigid material.

A ventilating or heating/cooling element having a first side having an air permeability of 15-800 m.sup.3/m.sup.2/h at 120 Pa. The first side is for directing an air flow toward a person. The ventilating/cooling/heating element may form or form part of a mattress, a duvet/blanket, a pillow, a sleeping bag, a seat, a clothes item or the like. A pump may be provided for providing air into the ventilating/cooling/heating element, or one or more openings may be provided for receiving air when a person is moving, such as when riding a motor cycle.

A heating and cooling device is disclosed comprising at least one integral low voltage heating and cooling source and an efficient flexible heat distribution means having a thermal conductivity of from 375 to 4000 W/mK for distributing the heat and cool across a surface. Further aspects include thermal interface compounds to provide full thermal contact as well as the use of a phase change material to provide a long lasting heating and/or cooling effect without the use of external electrical input. Preferred applications include automotive and furniture seating heating and cooling, along with outdoor garments having distributed heating and cooling effects.

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.

A unitary garment heating device that integrates with a garment to provide uniform heat throughout the garment. The device includes a plurality of nodes that position on various areas of the garment to distribute the heat. The nodes are fabricated from a conductive metallic yarn. A continuous conduit having no junctions carries current for generating heat, and connects the nodes to form a unitary heating device. The conduit is fabricated from the same material as the nodes, thereby forming a unitary device. The lack of junctions on the conduit helps eliminate problems such as shorts, and moisture exposure form rain or sweat. The conduit runs in a series circuitry to minimize shorts and arcing. The conduit is covered with a laminate and urethane to inhibit contact with moisture. A communication apparatus, such as a smart phone, monitors and regulates the temperature. A power supply and microprocessor are also attached.

A temperature-regulating garment is provided for assisting a user with regulating body temperature. A garment body has first and second major garment body edges. The garment body has a neckline formed by a least a portion of the first major garment body edge. The garment body has a front right panel, a front left panel, and a back panel. At least one armhole is located laterally between the back panel and a selected one of the right front panel and the left front panel. First and second neck pockets are each configured to accept a temperature-regulating pack. The first neck pocket is disposed upon at least one of the right front panel and the back panel, spanning the first major garment body edge. The second neck pocket is disposed upon at least one of the left front panel and the back panel, spanning the first major garment body edge.

Provided is an intelligent self-heating garment, whereby the temperature of the garment is adjusted according to the user's intuitive action based on the experience. The garment includes: a garment body; a heater provided in the garment body; a controller adjusting a heating temperature of the heater; and a temperature adjusting unit inputting an adjusting signal to the controller, and the adjusting signal being used for adjusting the heating temperature, wherein the temperature adjusting unit adjusts intensity of the adjusting signal according to a change in a size of an aperture provided in the garment body through which a body part of a user passes.

A heating system, such as embedded in a fabric object, such as a wearable garment, comprising at least one heating element comprising an electrical resistance heating loop, the heating element comprising at least one sense wire for detecting and providing a signal indicative of a safety condition, and a controller connected to the at least one heating element and to the sense wire and configured to shut down the heating element in response to the signal indicative of the safety condition. Multiple, independently controllable heating elements in a garment may be connected to a harness and one or more integral battery packs with a power management system to permit hot swapping of the battery packs. The garment may be configured to be communicatively paired to a mobile device to provide hands free phone, music streaming, and/or a user interface for the heating system.
