Specific dimensions and other physical characteristics relating to the embodiments disclosed herein are therefore not to be considered as limiting, unless the claims expressly state otherwise.

(11) In one embodiment of the present invention, described in FIGS. 1-7, a unitary garment heating device 100 integrates with a garment to generate heat in a predetermined area of the garment, such as the back and chest areas. The device 100 transfers the heat uniformly throughout the garment with a unitary, continuous conduit 104. The conduit 104 carries a current that generates the heat. The conduit 104 traverses in a series circuitry 400, so as to enhance uniform distribution of heat and minimize circuitry problems on the garment. The continuous configuration of the conduit 104 also helps enhance the structural integrity of the device 100, and eliminates the need for junctions. In some embodiments, pluralities of fabric heating nodes 102 are connected by the conduit 104. The nodes 102 serve to distribute the heat from the conduit 104 onto the predetermined areas of the garment. Similar to the conduit 104, the plurality of nodes 102 do not have junctions, but in essence, are one piece of conductive fabric divided and spaced to create sufficient flexibility on a garment. The nodes 102 and the conduit 104 are fabricated from substantially the same material—a metallic yarn 702.

(12) In some embodiments, each node 102 may be sufficiently flexible as to enable normal movement while wearing the garment. Further, the plurality of nodes 102 may be spaced as to enable bending, twisting, and folding over. These various orientations may provide comfort and flexibility, along with warmth, during use of the garment. The plurality of fabric heating nodes 102 may be fabricated from a metallic yarn 702 that integrates into the body of the nodes 102 by weaving or embroidering thereto. The metallic yarn 702 may include a copper and stainless steel composition, and may be configured to conduct a current, whereby the current provides the thermal energy to generate heat.

(13) In some embodiments, the plurality of fabric heating nodes 102 are connected by a conduit 104, having substantially the same composition as the nodes 102. The conduit 104 forms a single component that traverses the nodes 102 to carry an electrical current or other energy transfer, for providing the heat. In another embodiment, each node 102 may comprise two layers that overlay the conduit 104 from opposite sides, as illustrated in FIG. 1A. A proximal layer 114 engages the garment, forming a barrier against the skin. A distal layer 116 may form the opposite cover, and integrate with the conduit 104. An adhesive may help integrate the conduit 104 to the distal layer 116. Each layer 114, 116 is configured to transfer a predetermined amount of heat generated by the conduit 104 to the garment. This sandwich configuration enables the conduit 104 to remain a unitary, continuous member having no junctions.

(14) In some embodiments, the conduit 104 forms a single conducting member with no junctions, such as crimps, splices, or solders. This unitary, continuous configuration provides numerous advantageous and novelty to the device 100. Those skilled in the art will recognize that electrical junctions are points where power loss may occur as current is interrupted and shorts are possible. Further, junctions may be susceptible to wearing, and thereby contamination by moisture or dirt. In some embodiments, the conduit 104 traverses the nodes 102 in a series circuitry configuration 400, rather than a parallel or other type of circuitry. The series circuitry 400 of the conduit 104 and nodes 102 enables all sections of the conduit 104 to carry the same amount of current; and thereby generate substantially the same units of heat in each node 102. In one embodiment, the conduit 104 may include substantially the same metallic yarn 702 composition as the nodes 102, as illustrated in FIG. 1B. The conduit 104 includes a plurality of laminated layered sheets 110 that are coated with a urethane 112 to inhibit exposure to moisture and other contaminants, as illustrated in FIGS. 1A and 1B. In production, a unitary conductor 118 may include the metallic yarn 702 which may be formed in one continuous piece and coated with a urethane 120. An adhesive may help integrate the conduit 104 to the distal layer 116.

(15) In some embodiments, the device 100 may include a thermostat that indicates the temperature at specific areas of the garment based on the heat generated by the conduit 104. The thermostat may communicate with a remote communication apparatus that serves to monitor and regulate the temperature remotely. A software application may provide a graphical display of the heat generated and control functions for controlling the heat generated in the device 100.

(16) A power supply 106 for powering the conduit 104 may position on the nodes 102. The power supply 106 may include, without limitation, a battery, a fuel cell, or an external power source. A microprocessor 600 may control the amount and type of current flowing through the conduit 104. The power supply 106 provides power for the conduit 104, the thermostat, and the microprocessor/microcontroller 600.

(17) A first aspect of the present invention provides a unitary garment heating device 100 for generating heat throughout a garment through a unitary conduit 104, comprising: a plurality of nodes 102 configured to at least partially transfer heat to a garment, the plurality of nodes 102 disposed to interconnect, the plurality of nodes 102 comprising a heat conducting fabric, the plurality of nodes 102 further comprising a proximal layer 114 and a distal layer 116; a conduit 104 comprising a unitary conductor 118 having no junctions, the unitary conductor 118 including a metallic yarn 702 which may be coated with urethane 120 the conduit 104 further comprising the heat conducting fabric, the conduit 104 configured to generate heat for transfer to each node 102, the conduit 104 disposed to join each node 102 into a series circuitry 400 configuration, the conduit 104 further disposed to position between the proximal layer 114 and the distal layer 116; a power supply 106 configured to provide power to the conduit 104; and a thermostat disposed to operatively join with the plurality of nodes 102 and/or the conduit 104, the thermostat configured to indicate a temperature of the garment, the thermostat being configured to communicate with a communication apparatus, the communication apparatus configured to monitor and regulate the thermostat.

(18) In a second aspect, the garment comprises a jacket. The device 100 positions on a front and back area of the jacket. Heat may be transferred uniformly or in sectional areas throughout the garment through the use of a single conduit 104, rather than individual circuitry. In areas where the nodes 102 are not in contact with the garment, the conduit 104 provides heat thereto.

(19) In another aspect, the heat conducting fabric comprises a metallic yarn 702. The metallic yarn 702 comprises a copper and stainless steel composition.

(20) In another aspect, the plurality of nodes 102 comprises four nodes. The four nodes are sufficiently spaced to enable flexible movement while wearing the garment. Each node connects through the conduit 104 in a series circuitry 400 configuration.

(21) In another aspect, the series circuitry 400 configuration of the conduit 104 enables the conduit 104 to interweave throughout each node 102 in a proximal pattern without risk of arcing or shorting out. This generates a more compact, efficient heat.

(22) In another aspect, the conduit 104 comprises substantially the same material composition as the plurality of nodes 102. The conduit 104 further is fabricated from a plurality of sheets that are coated with a urethane. The urethane helps to inhibit contact with moisture. The conduit 104 is disposed to position between the proximal layer and the distal layer, while interconnecting the plurality of nodes 102. The conduit 104 integrates with the distal layer. The proximal layer forms a barrier to inhibit contact between the conduit 104 and the garment or skin. The proximal layer comprises a fleece material.

(23) In another aspect, the power supply 106 provides power to the device 100, and includes a battery, a fuel cell, or an external power source. The power supply 106 is configured and positioned to minimize interference while wearing the garment.

(24) In another aspect, the communication apparatus comprises a smart phone that communicates with the thermostat through a software application. The software application provides a display of the temperature on the garment or areas throughout the garment. The software application may also regulate the temperature based on external conditions, such as region, activity being performed, or time of day.

(25) As referenced in FIG. 1, the unitary garment heating device 100 comprises a plurality of nodes 102 and a conduit 104 configured to at least partially transfer heat to a garment. The garment may include, without limitation, a jacket, a sweater, a pair of trousers, and a hat. In other embodiments, the garment may, however, include a blanket or a bed sheet. The pluralities of nodes 102 are disposed to form an integral heating relationship with the garment. Each node may interconnect through the unitary conduit 104. In this manner, a uniform heating device 100 is maintained.

(26) In some embodiments, the pluralities of nodes 102 include a heat conducting fabric, such as a metallic yarn 702. The metallic yarn 702 may comprise copper and/or stainless steel material. In other embodiments, other materials conducive to conduction may, however, be utilized. In one embodiment, the metallic yarn 702 may include a strand of Bekaert yarn 3.6 meters long, and having a resistance of 2.5 ohms. It is significant to note that the unitary composition of the device 100 creates a uniform resistance that provides uniform heat distribution and eliminates bottle neck heat buildup in the garment. This uniform heat distribution on the garment may be observed in a thermal image 200 (FIG. 2).

(27) In some embodiments, the plurality of nodes 102 also includes a proximal layer and a distal layer. The proximal layer engages the garment, forming a barrier to inhibit contact between the conduit 104 and the garment or skin. The proximal layer may include a fleece material. The distal layer may form the opposite cover, and integrate with the conduit 104 through weaving or embroidering.

(28) Turning now to FIG. 3, the plurality of nodes 102 comprises four nodes, with two nodes engaging the chest area and two nodes engaging the back area of the garment. The nodes 102 may be connected by the conduit 104. The generated heat is continuous throughout the conduit 104 and the nodes 102. This continuity minimizes the needs for junctions, crimps, solders, and other connection points that create shorts and are susceptible to moisture. In some embodiments, the spacing between the pluralities of nodes 102 is sufficient to enable flexibility and bending. The flexibility provided by having multiple nodes 102, rather than a single node, is efficacious for enabling a user to actively wear a garment. In another embodiment, the plurality of nodes 102 comprises three nodes. Any number of nodes 102 may, however, be utilized depending on the type and size of garment.

(29) The device 100 further comprises a conduit 104 fabricated from substantially the same material of metallic yarn 702 as the plurality of nodes 102. The conduit 104 further is fabricated from a plurality of sheets that are coated with a urethane composition. The urethane helps to inhibit contact with moisture. Those skilled in the art will recognize that moisture from exterior elements or sweat is common on garments. This moisture exposed on an open junction or uncovered conduit 104 may cause shorts or corrosion to the device 100.

(30) In some embodiments, the conduit 104 is disposed to position between the proximal layer and the distal layer, while interconnecting the plurality of nodes 102. The conduit 104 integrates with the distal layer. The proximal layer forms a barrier to inhibit contact between the conduit 104 and the skin. The proximal layer comprises a fleece material. In other embodiments, any nonwoven material, cotton, polyester, or synthetic fiber may, however, be used.

(31) The conduit 104 comprises a unitary conductor 118 having no junctions. The lack of junctions and sharp corners in the conduit 104 helps minimize fraying of the metallic yarn 702 material at connection points. Also, crimp connectors used with certain types or extended lengths of stainless steel yarn may overheat when connected to heated yarns and current is run through the joined network of elements. The lack of junctions helps eliminate some of these problems. The conduit 104 comprises substantially the same material as the plurality of nodes 102. The conduit 104 configured to carry and generate heat for transfer to each node. Additionally, the conduit 104 not only carries current for transferring heat to the nodes 102, but also provides heat. In this manner, garment areas not in contact with the nodes 102 are heated through contact with the conduit 104.

(32) As referenced in FIG. 4, the conduit 104 is disposed to join each node 102 into a series circuitry configuration 400. The series circuitry 400 configuration of the conduit 104 enables the conduit 104 to interweave throughout each node 102 in a proximal pattern without risk of arcing or shorting out. This generates a more compact, efficient heat. Those skilled in the art will recognize that a parallel circuitry may create arcing between electrical conduits, and may also result in uneven distribution of heat. The series configuration of the conduit 104 inhibits the arcing and creates more uniform heating throughout the garment.

(33) In some embodiments, a thermostat disposed to operatively join with the plurality of nodes 102 and/or the conduit 104. The thermostat is configured to indicate a temperature of the garment. In one embodiment, the device 100 includes input for a 20K thermistor resistor component for feedback to control the actual temperature of the device 100. This resistor can be connected to a probe to detect and control actual temperature in addition to only relying on a user's subjective comfort levels.

(34) In some embodiments, the thermostat may include a receiver to communicate with a communication apparatus, such as a smart phone. The display on the smart phone, as referenced in FIGS. 5A, 5B, 5C, and 5D, can include the temperature depicted in a graph and color coded. The actual temperature, though, may be affected by the ambient temperature. In other embodiments, the communication apparatus for monitoring and regulating the temperature of the device 100 may include a remote control station, a server, a computer, and a laptop. The communication apparatus operatively communicates with the thermostat and a microprocessor 600 on the device 100 to optimally monitor and regulate the thermostat. For example, the communication apparatus can display and enable control of a Low Temperature 502 between 0°-25° Fahrenheit (FIG. 5A), a Moderate Temperature 504 between 26°-50° Fahrenheit (FIG. 5B), a High Temperature 506 between 51°-75° Fahrenheit (FIG. 5C), and for therapy, such as massages and the like, a therapy Temperature 508 between 76°-100° Fahrenheit (FIG. 5D). These temperatures may be regulated remotely or directly through the thermostat.

(35) In another embodiment, the display on the smart phone, as referenced in FIGS. 6A, 6B and 6C, shows other exemplary smart phone application interfaces. A radar key symbol 601 on the top of the smart phone display shows the running status of the smart phone application interfaces. As shown in FIG. 6A, the interface 602 can include an easy to control jacket temperature controller button 608, that can control temperature of the jacket by just sliding the button 608 over a mercury reading bar 610. The mercury reading bar 610 indicates different levels such as OFF, Low temperature (90° F.), Medium temperature (105° F.) and Maximum temperature (130° F.) on the bar 610. The interface 602 also shows a set temperature value 612 for the jacket and current jacket temperature value 614. It also shows current weather condition such as current atmospheric temperature 616 on the display. A compass 618, a Bluetooth status button 620 and a flash light button 622 are shown on the interface 602. As shown in FIG. 6B, the interface 604 used during navigation showing the compass 618 for determining direction of navigation while showing other parameters such as the flash light button 622, the set temperature value 612 for the jacket, the current jacket temperature value 614, and the current atmospheric temperature 616 on the display. As shown in FIG. 6C, the interface 606 displays detailed weather condition 624 of a selected location over the map while showing other parameters such as the set temperature value 612 for the jacket and the current jacket temperature value 614 on the interface. Other several modifications to the smart phone application interface can be done to show and control the jacket temperature without departing from the scope of the invention.

(36) In some embodiments, a power supply 106 provides power to the conduit 104 and the thermostat. The power supply 106 may include, without limitation, a battery, a fuel cell, or an external power source. The external power source may include an electrical socket that joins the device 100 through an electrical cable. The power supply 106 is configured and positioned to minimize interference with functionality and comfort of the garment. In some embodiments, a USB port 710 may operatively attach to the power supply 106 and transfer excess power to electronic phones, laptops, and computers. Those skilled in the art will recognize that joining the power supply 106 with the USB port 710 reduces the number of components, and thereby reduces manufacturing costs.

(37) Those skilled in the art will recognize that varying parameters such as, the power supply 106, yarn dimensions, resistance of the conduit 104, and garment thickness may provide different heating capacities. For example, without limitation, the power supply 106 voltage required to obtain 120° F. on the yarn in the nodes 102 and conduit 104 would require 9 W/m of power. If 1 meter of yarn in a glove garment, with a 3.7 volt battery, the current may flow at 2432 mA (9/3.7V) and the resistance 1.52 ohm (3.7V/2.432 A). The power supply 106 would last for 54 minutes at full power. In another embodiment, the yarn may, however, include a resistance of 2.6 ohm/m. This results in the resistance of 1.52 ohm/m not being possible to obtain with one single yarn. It would require two pieces of 58 cm of 4.5 ohm/m yarn. These embodiments assume a series circuitry 400 configuration. If parallel, the consumption would be 2840 mA and the one battery would last 45 minutes at full power at 120° F. In this case, the maximum discharge current of the battery should be in the range of 3000 mA, but the issues with parallel discussed above would be present. With two batteries of 3.7V (for a total of 7.4V), 1.16 m of yarn would be needed to obtain 120° F. on the yarn. In this case, the consumption of electrical current would be about 1420 mA, and power supply 106 would last approximately 1 hour, 30 minutes.

(38) FIG. 7 references the key components of the unitary garment heating device 100 utilizing a power delivery and thermal management system 700 that allows the power supply 106 to heat the metallic yarn 702 through the conduit 104 thereby providing uniform heating throughout the garment. The power supply 106 is attached with a USB port 710 and a battery charging circuit 704 that allows recharging of the power supply from the USB port 710 on a laptop or PC. An on board DC-to-DC converter is present to step up the 5-volt signal to a level adequate to charge the respective power supply 106. Further the charging circuit 704 is configured and positioned to minimize interference with functionality and comfort of the garment. The power source optionally charges a portable electronic item with the power supply charger 704 through the USB port 710, which may operatively transfers excess power to electronic phones, laptops, and computers. The thermal management system 700 regulates the temperature of the garment with a communication apparatus regulator display 706 upon receiving signal from the thermostats or thermal sensors 703. The temperature of the garment in association with heating element or the conduit 104 is sensed by the sensor 703, wherein the sensor sends the signal to the embedded microprocessor/controller 600 and is transmitted to the communication device through the integrated wireless communication controller 705. The communication devices are equipped with application user interface to provide control over the parameters via the communication apparatus regulator display 706. The microprocessor 600 combined with another USB port or any other port acting as a heating port 708, which includes an input for a thermistor resistor component for feedback to control the actual temperature of the conduit 104. Other additional signals, user controls and indicators 707 can be sent and received from the integrated wireless communication controller 705, so as to regulate the temperature of the garment or generate other statistical or graphical information which may be used to alert the user or other several applications. These multifunctional aspects may be done simultaneously and remotely. In other embodiments, additional functions related to heating the garment may, however, be allowed through the power delivery and thermal management system 700.

(39) The controller 600 may include, without limitation, a MicroChip model PIC 12C672 microcontroller 600. In some embodiments, the USB port 708 may include an input for a 20K thermistor resistor component for feedback to control the actual temperature of the conduit 104. In another embodiment, the microcontroller 600 comprises a power metal-oxide-semiconductor field-effect transistor (MOSFET) system for the actual power control which is driven by a pulse width modulation signal derived from the microcontroller 600 and associated firmware.

(40) Multiple power sources 106 like a direct electrical power supply, or battery as a power source or receiving to power from one or more electric equipments through USB port or a solar panel can supply power to the unitary garment heating device 100. Further the device can be equipped with multiple temperature sensors and thermostats 703 may be connected to different areas of the garment 100 to send the temperature sensed at that area, multiple heating ports 708 may be equipped with the thermal management system 700, so as to allow several heating elements or conduits 104 to be connected to the same thermal management system 700, multiple USB ports 710 and non-USB ports can be connected to the unitary garment heating device 100 allowing several equipments can be connected to the thermal management system 700 for the purpose of communications as well as charging.

(41) These and other advantages of the invention will be further understood and appreciated by those skilled in the art by reference to the following written specification, claims and appended drawings.

(42) The foregoing descriptions of specific embodiments of the present invention have been presented for purposes of illustration and description. They are not intended to be exhaustive or to limit the present invention to the precise forms disclosed, and obviously many modifications and variations are possible in light of the above teaching. The exemplary embodiment was chosen and described in order to best explain the principles of the present invention and its practical application, to thereby enable others skilled in the art to best utilize the present invention and various embodiments with various modifications as are suited to the particular use contemplated.
