     FIELD OF THE DISCLOSURE 
     This disclosure relates generally to electrically-powered garments; electrically-heated garments; electrically-heated garments with rechargeable power sources; chargers for electrically-powered garments; charging garment hangers; garments heated and cooled using fluids/gases; garments with integrated and attachable sensors; networked electrically-powered garments; interconnected groups and networks of electrically-powered garments and/or their rechargeable power sources; devices for powering, charging, configuring, and controlling such garments and groups/networks of garments and their rechargeable power sources; and methods for operating, configuring, and collecting data from such garments, groups of garments, and devices. 
     BACKGROUND 
     The textile and garment industries are undergoing a significant evolution. For much of the history of the textile industry, cotton, linen, leather, hemp, and silk have been the primary materials for garment production. In the early part of the last century, nylons and polyesters were added as staple textiles. As materials sciences evolve and weaving techniques improve, textiles are being developed that have unique desirable properties. Further, textiles and garments are being created that allow for sensor and other devices to be integrated into the textile or designed into the garment. 
     The performance of individuals quickly diminishes in environments that push body temperatures above or below about 98.6 degrees Fahrenheit. To enhance performance and comfort, a garment may be insulated to provide to the wearer protection against high and/or low temperatures. Insulation, however, may increase the dimensions and/or weight of the garments, and may inconvenience the wearer. A need in the art exists for garments that provide added protection against heat and/or cold, yet do not excessively inconvenience the wearer. To enhance the performance of individuals further, it would be useful to monitor physiological attributes and states of the individuals. A need in the art exists for garments that facilitate collection of biometric, environmental, and other information during use. With the integration of heating and cooling capabilities into a garment and with the increased use of garment biometric sensors, a need in the art exists for improving function control and configuration of powered garments by the wearer. Additionally, with the integration of these functional devices into a textile or garment, electrical power is necessary to support operations of these devices. For convenience, rechargeable battery technology may be used. Therefore, a need in the art exists for improving electrical recharging of garments with rechargeable power sources.

The electrical/electronic components may be interconnected by wiring; one wire  180  running along a garment seam is partially shown in  FIG.  1   . In embodiments, some or all of the wiring may be routed along seams of the jacket  100 . 
     Although the electrical/electronic components of the jacket (or another garment)  100  are schematically shown as separate devices, some or all of them may be combined. Thus, in examples, all of the components are combined in the enclosure of the battery  140 . In examples, the control button is a separate component, and all or at least one other components are combined with the battery. More generally, any two or more of the components may be combined. 
       FIG.  2    illustrates selected components of a charging clothing hanger  200  designed to receive the jacket  100 . The hanger  200  includes a body  210 , a hanging hook  220 , a hanger charging interface  230 , and electrical/electronic components for charging and/or interfacing with the jacket  100 . Here as well all or any two or more of the components of the hanger  200  may be combined. 
     The battery  140  may be a rechargeable battery, for example, a Nickle Cadmium (NiCad) battery, a Nickle Metal Hydride (NiMH) battery, a Lithium Ion (Li-Ion) battery, a Lithium-Polymer (LiPo) battery, or any other electrical energy storage device, including capacitors and supercapacitors. Note that the battery  140  may have one or several cells, connected in series, in parallel, or otherwise. The battery  140  may be placed, for example, in the pocket  135 , either directly or into a sub-pocket (inside the pocket  135 ) designed to receive the battery  140 . The battery  140  may be connected and provide power to one or more of the other electrical/electronic components of the jacket  100  that need power to operate, such as the heating element(s)  165 , the wireless transceiver  150 , the controller  155 , the sensor(s)  170 , the control button  175 , and possibly others. The battery  140  is also connected to the garment charging interface  145  and/or the regulator  160 , to receive electrical power through these components and recharge. 
     The garment charging interface  145  is designed to couple to the hanger charging interface  230  of the hanger  200 . In embodiments, the two charging interfaces are designed to couple electrical energy via electrical induction. Thus, the hanger charging interface  230  may include a sending coil driven with an alternating frequency, and the garment charging interface  145  may include a receiving coil. When the two coils are substantially parallel and/or near each other, they couple inductively, and electrical energy can be transferred from the hanger charging interface  230  to the garment charging interface  145  by driving the sending coil of the interface  230  with alternating current (AC). Thus, the locations of the two charging interfaces may be such that when the jacket  100  is hanged on the hanger  200 , the two charging interfaces are near each other to allow the inductive transfer of energy from the hanger charging interface  230  to the garment charging interface  145 . Inductive transfer of energy can be effected using AC at 50 Hz or 60 Hz, for example. More generally, inductive coupling between the two charging interfaces may be effected at lower or higher frequencies. In examples, the inductive coupling is such that less than ten percent of the energy available to the hanger charging interface  230  for sending to the garment charging interface  145  is radiated by the hanger charging interface  230 . In examples, the operating frequency is below 100 KHz; in more specific examples, the operating frequency is below 10 KHz; in still more specific examples, the operating frequency is 1 KHz or less. In examples, each of the interfaces  145 / 230  is a coil, with a magnetic core to enhance the inductive coupling between the interfaces  145 / 230 , such as 50-60 Hz transformer cores, including laminated and non-laminated metal cores. In examples, the magnetic cores may be formed so that one fits (approximately) in the other; for instance, the hanger&#39;s core may form a cylindrical or conical opening (with the broad part of the conical opening facing towards the garment), and the garment&#39;s core may form a conus fitting into the hanger&#39;s conical opening, or a cylinder fitting inside the hanger&#39;s cylindrical opening. In examples, however, one or both of the interfaces  145 / 230  do not include transformer-like cores. 
     In embodiments, the alignment of (and therefore mutual coupling between) the interfaces  145 / 230  is improved by inclusion of magnets in each of the interfaces. The magnets may be oriented so that when the jacket  100  is hanged on the hanger  200 , the two magnets attract the interfaces  145 / 230  to each other, and therefore bring them into closer proximity; for example, the interfaces  145 / 230  may come into contact with each other under the force of the magnetic attraction between the opposite poles of their respective magnets. In examples, however, only one of the interfaces  145  or  230  includes a magnet, while the other interface includes a magnetic member that is attracted to magnets, and specifically to the magnet of the first interface. The interface  145  may include a magnet, while the interface  230  may include the magnetic member that, while not necessarily a magnet itself, is attracted to the magnet of the interface  145 . Analogously, the interface  230  may include a magnet, while the interface  145  may include such magnetic member. In examples, the magnetic member is not a separate element, but the inductive core of the interface in which it is incorporated (the interface  145  or the interface  230 , as the case may be). Thus, such a magnetic member may serve two related functions: help bring the two interfaces  145 / 230  nearer each other, and improve the inductive coupling between the two interfaces  145 / 230  by improving the transformer-like properties of the combination of the sending and receiving coils of these interfaces. 
     The detailed description of inductive coupling should not be understood as excluding electromagnetic coupling using higher frequencies, for example, RF frequencies. Thus, in embodiments, the hanger charging interface includes an RF radiator antenna driven by appropriately designed/configured power circuitry of the hanger at radio frequency, and the garment charging interface may include an RF radiation receiver antenna coupled to appropriate circuitry (e.g., of the regulator  160 ) for converting the energy of the received RF emissions into the electrical energy suitable for recharging the battery of the garment. 
     The interfaces  145 / 230  may include contacts to allow charging current to flow from the interface  230  into the interface  145 , and the magnets may couple the interfaces  145 / 230  so that the contacts couple with the right polarity, plus-to-plus, minus-to-minus. The polarity of the contacts may be controlled with the polarity/orientation of the magnets in the respective interfaces  145 / 230 ; in other words, the polarity of the magnets may be such that the contacts couple correctly when the interfaces  145 / 230  come together under the forces generated by their respective magnets. North-to-South and South-to-North. In other embodiments, the physical shapes of the interfaces  145  and  230  include protrusions and openings/indentations that come together one way to assure that the contacts couple correctly and prevent the opposite (incorrect) coupling of the contacts. As will be discussed in more detail below in relation to  FIGS.  7 A and  7 B , there may be additional contacts on the interfaces  145 / 230 , to allow flow of signals. The contacts of the interfaces  145 / 230  may touch each other without manual involvement beyond hanging of the garment on the hanger; this will also be discussed in more detail below. An advantage of such mechanical (non-inductive) coupling arrangement may be that there is no need to provide alternating current drive to the interface  230  or to rectify the received AC on the side of the interface  145 , simplifying the electrical/electronic components of the interfaces  145 / 230  and likely improving the efficiency of the energy transfer from the hanger  200  to the jacket  100 . 
     In examples, several hanger charging interfaces may be present on the hanger such as the hanger  200 , and, correspondingly, several garment charging interfaces may be present on the garment such as the jacket  100 . Including several pairs of garment-hanger charging interfaces, for example, pairs of the interfaces such as the interfaces  145 / 230 , may reduce charging times and increase the likelihood that at least one of the pairs will be functional when a garment is hanged somewhat askew. Examples of such arrangements of multiple hanger charging interfaces are illustrated in  FIG.  3   ,  FIG.  4   , and  FIG.  5   . 
     In embodiments, the interfaces  145  and  230  are or include electrical couplers such as connectors that a user (e.g., the wearer of the jacket  100 ) plugs into each other when the user hangs the jacket  100  on the hanger  200 . 
     As has already been mentioned, a single hanger may have multiple hanger charging interfaces, and a single garment such as a jacket may also have multiple garment charging interfaces. Note that the multiple hanger charging interfaces included on one hanger may be of different types, as can be multiple garment charging interfaces on a single garment. For example, a mechanical connector-type charging interface may coexist with an inductively coupled charging interface on the same item such as the jacket  100  and the hanger  200 . Moreover, multiple hanger charging interfaces may be used to charge multiple garments in parallel, at the same time. 
     The regulator  160  receives the electrical power from the garment charging interface  145 , converts/conditions the received power so it can be used to charge the battery  140 , and charges the battery  140  as needed while the interface  145  receives the power from the interface  230 . Conversion may include rectification, smoothing/filtering, regulation to a lower or sometimes a higher voltage, and/or other functions. The operation of the regulator  160  may be controlled, in whole or in part, by the controller  155 . 
     In embodiments where the interfaces  145 / 230  are designed for mechanical coupling (i.e., non-inductive coupling, such as electrical contacts and manually coupled male-female connectors), the power received from the hanger charging interface may be suitable for charging the battery  140  directly, without conversion or conditioning. In such embodiments, all or part of the charging circuitry may be built into or connected to the hanger such as the hanger  200 . 
     The wireless transceiver  150  may be a Bluetooth® transceiver or another type of short range radio frequency (RF) transceiver. The wireless transceiver  150  may be capable of pairing with various other RF devices, such as other Bluetooth®-enabled devices, and sending data to and/or receiving data from these devices. In examples, the wireless transceiver  150  has a communication range of less than 100 meters; in more specific examples, the communication range is less than 10 meters; in still more specific examples, the communication range is less than 1 meter. 
     The controller  155  may be a general purpose microprocessor or a microcontroller capable of executing code stored in the internal memory of the controller  155 , or in another memory that is one of the electrical/electronic components of the jacket  100 . The controller  155  may also be a dedicated processor, for example, an application-specific integrated circuit processor, field-configurable processing logic, a number of discrete components implementing control circuitry, or another kind of processor. The controller  155  may be connected to any of the other electrical/electronic components, to change their states and/or read data from these components. 
     Each of the heating elements  165  may be a resistive heating element, such as a resistive wire, coiled, straight, or otherwise arranged. In embodiments, each or some of the heating elements  165  may include piping allowing a warm/hot fluid or gas (“thermal flow agent”) to flow, controlled by a fluid or gas valve that controllably allows and interrupts the flow of the fluid or gas. Note that the thermal flow agent may also or instead carry cooling air or fluid, for controllably cooling the jacket/garment and the wearer of the jacket/garment; in embodiments where the element  165  may provide cooling instead of or in addition to cooling, it may be referred to as a “thermal control element” or “thermal control device.” The electrical drive of the element  165  or the state of the fluid/gas valve may be controlled by the processor  155 . 
     The sensors  170  may include biometric sensors, such as heart rate sensors, breathing rate sensors, temperature sensors, blood pressure sensors, movement sensors, and other sensors. The processor  155  may be connected to the sensors  170  to read data from the sensors  170 , and to configure the sensors. More generally, the processor  155  may be connected to all or some of the sensors  170  and to any and all other electrical/electronic components of the garment  100  with wired and/or wireless connections; the wired connections may be USB connections: the connections may implement a data bus, serial or parallel. As will be elaborated below, the processor  155  may be connected in the same fashion to sensor(s), processor(s), and/or any other electrical/electronic components of other powered garments, particularly powered garments worn at the time by the same user. 
     The control button  175  may be coupled to the processor  155  and provide an interface between the wearer of the jacket  100  and the processor. The interface may include both or either input(s) and output(s). In examples, the button  175  includes one or more color LEDs (or other light emitters) that indicate the status of the jacket  100 . For example, different colors and/or color intensities emitted by such light emitters may indicate different intensities of the drive to the heating element(s)  165 . For example, four different LED colors may indicate 25% of maximum output power, 50%, 75%, or 100%; more generally, any number of power levels may be programmed. The control button  175  may also include a switch, such as a toggle switch. For example, pressing the button may turn the electrical/electronic components on and sequentially increase the power drive to the heating elements  165 ; pushing it once may turn the drive on at 25% of the maximum output power, pushing the button for the second time may increase the drive to 50%, pushing the button the third time may increase the drive to 75%, and pushing the button the fourth time may increase the drive to full power output, and pushing the button again may turn the power off. The LED colors or intensities may change accordingly, as described in this paragraph and elsewhere in this document. 
     The control button  175  may also be used to input additional commands to the processor  155  and control multiple functionalities of the garment  100 . For example, the wearer can press the control button and hold it depressed for longer and shorter periods of time, and such single button pressings/clicks and/or sequences of long/short pressings/clicks can be interpreted by the processor  155  according to a predetermined correspondence between various commands and single or multiple pressing s/clicks. The predetermined correspondence may be stored, for example, as a table in the internal memory of the controller  155  or in another memory that is one of the electrical/electronic components of the jacket  100 . The controller may also activate the lights of the control button  175  and/or other lights that of the electrical/electronic components of the jacket  100 , to assist the user in inputting desired commands. For example, if the jacket  100  has several heating panels or zones that can be controlled separately, the user may press the button  175  in predetermined ways to turn from controlling one panel or zone of the jacket  100  to another, and then input power control command once the user selects the desired panel/zone. As the user switches from one panel to another, the processor  155  may turn on LED or another light built into or placed near the currently-controlled panel so that the user can visually confirm that the user is controlling the desired panel. Similarly. LEDs or lights may be built into various sensors and the user may switch from programming one sensor to another and visually confirm the selected sensor. It is also contemplated that in certain embodiments the described visual indicators could be replaced by audible or haptic indicators. As will be elaborated below, additional powered garments may be coupled to the garment  100 , particularly powered garments worn at the time by the same user, and be controllable by the garment  100 ; the control button  175  may be used to program/control these connected powered garments, 
     In embodiments, the garment charging interface  145  is built into the main label of the garment  100 . 
     The electrical/electronic components of the hanger  200  may include a transformer with a cord pluggable into electric outlets, rectification circuitry, smoothing/filtering circuitry, downconversion and/or regulation circuitry, inversion circuitry for converting the downconverted/regulated AC into AC suitable to drive the hanger charging interface  230 . In embodiments, however, the transformer of the electrical/electronic components of the hanger  200  converts the voltage of the AC from the cord to AC at a voltage suitable for driving the hanger charging interface  230 . In embodiments, the AC from the cord drives the hanger charging interface  230  directly, without voltage downconversion. In other embodiments, the electrical/electronic components of the hanger  200  include components for producing a DC source that directly, or through a regulator or other downconversion circuitry, can charge the battery  140 ; this may be the case if the interfaces  145 / 230  are or include connectors pluggable into each other or contacts touching each other, as has already been mentioned and will be described in more detail below. In another configuration, the electrical/electronic components of the hanger  200  include a battery, which may have capacity larger and even substantially larger (3-15 times) than the battery  140  of the garment  100 , and circuitry to convert the DC voltage from the battery of the hanger to charge the battery  140  of the garment. For example, the hanger  200  may include an inverter and other circuitry to convert the DC of hanger battery into AC that drives the hanger charging interface  230 ; as another example, the battery of the hanger charges the battery  140  of the hanger  100  directly or via regulator and/or another type of voltage downconverter, at a lower or sometimes a higher voltage. 
       FIG.  3    illustrates a hanger  300  with a main body  310 , a hook  320 , and two hanger charging interfaces  330 A and  330 B, positioned on each side extension or “wing” of the hanger  300 . The hanger charging interfaces  330 A/ 330 B may be inductive interfaces and/or contact interfaces, for example. Here and elsewhere in this document and the attached drawings, an inductively-coupled hanger charging interface may but need not extend beyond the surface of the hanger, and may be effective in both front and rear directions. In this way, however the garment is hanged, the hanger charging interface may send electrical power to a corresponding garment charging interface, or charge a powered garment and another device such as a spare battery. Thus, a contact hanger charger interface may have contacts on both its front and rear. Similarly, an inductive hanger charger interface may have sending coils on front and rear; alternatively, a single sending coil may be positioned so that it can couple inductively to receiving coils on both front and rear of the hanger. 
       FIG.  4    illustrates a hanger  400  with a main body  410 , a book  420 , and two hanger charging interfaces  430 A and  430 B on the different side extensions of the hanger  400 , as well as a third interface  430 C substantially in the center of and near the hook of the hanger  400 . Each of the hanger charging interfaces here may be, for example, a contact interface or an inductive interface. The hanger  400  also includes a hanger charging interface  430 D, which is a cord with an electrical connector on its end. 
       FIG.  5    illustrates a hanger  500  with a main body  510 , a hook  520 , and charging interfaces  530 A and  5308  on top of the opposite wings of the hanger  500 . 
     The magnetic coupling of the charging interfaces  145 / 230  may be extended to additional interfaces of additional devices. For example, the interface  230  may couple to the interface  145  on one side, and at the same time couple to another charging interface on the opposite side. 
       FIGS.  6 A,  6 B .  6 C,  6 D,  6 E,  6 F.  6 G, and  6 H illustrate different views of a foldable/portable hanger  600  capable of charging simultaneously a powered garment such as the jacket  100 , and one or more other devices, such as one or more batteries for providing electrical power to powered garment(s) or other battery-powered devices. The hanger  600  includes a body  610 , a hook  620  that can be folded into a matching hook recess  622  (shown in  FIGS.  6 C / 6 D) of the body  610 , extenders  655 A and  655 B that can be lowered into extender recesses on the sides of the body  610 , as well as extended, as is shown in some of the Figures. The hanger  600  also includes electrical/electronic components identical, similar or analogous to such components discussed in relation to the hanger  200 . Here, the body  610  includes an electrical receptacle  660  on the bottom of the hanger  600  ( FIGS.  6 F / 6 G), with prongs configured to receive electric power from a cord with a matching plug on one end. In some examples, the second end of the cord plugs into a wall receptacle (or a similar receptacle) providing common household/office power, say 110/220 VAC. In other examples, the cord also includes a power supply, such as a transformer and possibly also a rectifier/regulator for providing a lower AC or DC voltage to the hanger  600 . In still other examples, the cord may connect the hanger  600  to a IX power source such as a battery. The cord or the cord-power supply combination may be considered part of the hanger  600 . 
     The hanger  600  further includes hanger charger interfaces  630 A and  630 B, on front and rear surfaces of the hanger  600 . In  FIGS.  6   , the hanger charging interfaces  630 A are the same, one on the front and another on the rear of the hanger  600 . One of the interfaces is discussed, with the understanding that the same applies to the other hanger charging interface. 
       FIG.  7 A  shows the surface of the interface  630 A with four conductive electrical contacts with reference designators  632 - 1 ,  632 - 2 ,  632 - 3 , and  632 - 4 . The contact  632 - 1  covers the inside of a circle; and contacts  632 - 2  through  632 - 4  are concentric rings separated by insulating material from each other and from the contact  632 - 1 . The contacts of the interface  630  here may correspond to five USB contacts: Ground, Power+, Power−, Data+, and Data−, with the Ground and the Power-contacts combined and connected to the same circle. The USB pinout and inclusion of data transfer pins (such as Data+/Data−) are not necessarily required in all embodiments. Each of the interfaces  630 A/ 630 B also includes a magnet internal to the hanger  600 . The magnets are for attracting the magnets of the counterpart interfaces (to be discussed) on garment charging interfaces or batteries. The contact  632 - 1  may be part of a magnet of the interface, or the magnet may be located at the center of and under the surface of the interface  630 A. 
     The hanger charging interfaces  630 A/ 630 B also include electrical/electronic components, such as the electrical/electronic components of the hanger charging interface  230  of the charging clothing hanger  200 . Here, however, the electrical/electronic components may support two interfaces ( 630 A/ 630 B) rather than a single interface. In examples, however, two sets of some or all of the electrical/electronic interfaces are present, one per interface  630 A and  630 B. 
       FIG.  7 B  shows the surface of an interface  745  that is capable of mating with the interface  630 A. The interface  745  may be part of a garment, such as the interface  145  of the garment  100 . The external surface of the interface  745  includes five smaller contacts  747 - 1  through  747 - 5 . “Smaller contact” here means essentially a point contact, with a much smaller area (by at least a factor of 10, or even at least a factor of 100) than the total area of the surface of the interface of which it is a part. 
     When the illustrated surfaces of the interfaces  630 A and  745  come into contact so that the circles on each of the interfaces are concentric, the contact  632 - 1  (the inside of the conductive circle) will touch the contact  747 - 1 , the contact (conductive ring)  632 - 2  will touch the contact  747 - 2 , the contact  632 - 3  will touch the contact  747 - 3 , and the contact  632 - 4  will touch the contacts  747 - 4  and  747 - 5 . (Recall that the Ground and the Power-contacts may be combined). 
     Conductors internal to the interface  630 A connect the contacts  632  to the appropriate electrical/electronic components of the interface  630 A. In operation, these conductors may carry electrical energy from the garment charging interface  745  to the circuitry of the interface  630 A, and carry signals between the two interfaces  630 A/ 745 . Analogously, conductors internal to the interface  745  connect the contacts  747  to the appropriate electrical/electronic components of the interface  745 . In operation, these conductors may carry electrical energy from the garment charging interface  745  to the interface  630 A, and signals between the two interfaces. 
     As was already mentioned, the garment charging interface  630 A includes a magnet at the center. The garment charging interface  745  also includes a magnet at its center, under the surface with the contacts  747 . The two magnets are disposed (located) and oriented (North/South) so that they attract and bring the two surfaces together, concentrically, and the contacts  632  and  747  touch each other as is described above, and enable the flow of electrical energy from the interface  745  to the interface  630 A, as well as flow of signals between the two interfaces. Note, however, that interface of the charging device (e.g., of the charging hanger) may be like the interface  630 , and the garment interface may be like the interface  745 ; here, the flow of energy and the flow of signals would be reversed. 
     In examples, the two hanger charger interfaces  630 A and  630 B are identical or analogous, but facing in different directions. In other examples, the hanger charger interfaces  630 A and  630 B are different: one such as the interface  630 A with the circle and ring contacts and a locating magnet, the other with the rectangular or otherwise shaped smaller footprint contacts as described and shown above in relation to the interface  745 ; such embodiment is illustrated in  FIG.  6 I . (For this reason, the surface of the interface  630 B in some of the Figures does not show details.) Moreover, the two interfaces may be of different types, for example, one being a contact-based interface such as the interface  630 A, the other being an inductive interface. 
       FIGS.  8 A,  8 B,  8 C, and  8 D  illustrate selected features of a charger  800  with a garment charger interface  845 , which is identical, similar, or analogous to the garment interface  745  discussed above. The charger  800  also includes prongs  870  that may be plugged into a wall outlet, and a port  875  that may be a USB port capable of providing DC power and communicating using the USB industry standard. The electrical/electronic components of the charger  800  may be identical, similar, or analogous to the electrical/electronic components of the charging clothing hanger  200 , for example, including a transformer for downconverting the AC voltage from the wall outlet, rectification circuitry, smoothing/filtering circuitry, and DC regulation circuitry that provides DC voltage for charging a powered garment coupled to the hanger charging interface  845 . 
       FIGS.  9 A and  9 B  illustrate different views of a garment battery  900 , which is pluggable into a power receptacle of a powered garment, to provide electrical power to the garment. The garment may be such as the garment/jacket  100  and the battery  900  may be used as the battery  140 . Note charger interfaces  930 A and  930 B on opposite sides of the battery  900 . These interfaces are identical, similar, or analogous to the hanger charger interfaces  630 A and  845 , discussed above. Here, the interface  930 A is compatible with the interface  845  of the wall-pluggable charger  800 . Moreover, the interfaces  930 A are mutually compatible, meaning that an interface  930 A of one battery  900  can be connected to an interface  930 B of another battery  900 . Thus, the smaller (rectangular) contacts of the interface  845  of the charger  800  will touch the circular (inside the central circle, rings) contacts of the interface  930 A when the two interfaces are brought together; the smaller rectangular contacts of the interface  930 B of a first battery  900  will touch the circular contacts of the interface  930 A of a second battery  900 . Additionally, the magnets under the surfaces of the interfaces  830 / 930 A/ 930 B have such polarities that different interfaces attract: the interface  845  will therefore be attracted to the interfaces  930 A; and the interface  930 B on the first battery  900  will be attracted to the interface  930 A of the second battery  900 . And recall that the magnets are positioned so that the interfaces tend to be centered under the forces of magnetic attraction, so that the coupling of the two interfaces is proper for transmission of electrical power from the charger  800  to the batteries  900 , and from one battery  900  to another. 
       FIG.  10    illustrates selected features of a combination  1000  of a charger  800  and three batteries  900 . Note a port  912 - 2  on the battery  900 - 2  and a port  912 - 3  on the battery  900 - 3 . These are for connecting the batteries  912 - 2  and  912 - 3 , respectively, to the garment electronics, and possibly to other devices. The battery  900 - 1  has the same type of port on its lower side/edge, which is not visible in  FIG.  10   . As a person skilled in the art would readily understand after careful perusal of this document and the attached drawings, the circular contacts of the interface  930 A (the contacts  632  in  FIG.  7 A ) enable coupling the interfaces  930 A (or  630 A in  FIG.  7 A ) to the interfaces  9308  (or  745  in  FIG.  71   , or  845  in  FIGS.  8 A / 8 B) regardless of the relative circular orientation of the two devices (of the battery  900 - 1  relative to the charger  800 , and the battery  900 - 1  relative to the battery  900 - 2 , etc.). Thus, the batteries  900  and the charger  800  can be rotated 360 degrees on the axis that goes through the centers of the round interfaces  930 A/ 930 B. 
     Note also a port  914 - 2  on the battery  900 - 2  and  914 - 3  on the battery  900 - 3 . These ports may be physically and/or electrically different from the ports  912 , and may also be used for connecting the batteries to the garment electronics and/or to other devices. 
     Let us now turn back to the hanger  200  and its hanger charging interface  230 . In embodiments, the interface  230  includes an interface  230 - 1  and an interface  230 -B, respectively on the front and rear of the hanger. A single interface may be implemented with two surfaces and placed so as to enable charging of garments/batteries from both front and rear, for example, including interface surfaces such as  630  on both front and rear, as has already been mentioned in relation to  FIG.  6   .  FIG.  11 A  and  FIG.  11 B  show, respectively, selected features of the front and rear of a hanger  1100 , which is a version of the hanger  200  with this arrangement. The hanger  1100  includes a body  1110 , a hanging hook  1120 , hanger charging interfaces  1130 A and  1130 B, and electrical/electronic components for charging and/or interfacing with the jacket  100 . Any two or more of the components of the hanger  1100  may be combined. Each of the interfaces  1130 A/ 1130 B is similar to the interface  830  of the charger  800 ,  FIG.  8   ; it has five smaller contacts, such as the contacts  747 - 1  through  747 - 5 , arranged in the same way. The interface  145  of the garment  100  may then be such as the interface  930 A of the battery  900 . When the garment  100  is hanged on the hanger  1100 , the interface  145  will be near the interface  1130 A (or  1130 B, depending on the way the garment  100  is hanged). The two interfaces will be attracted because of their internal magnets, and will couple with each other and stay coupled, so that the circular contacts of the interface  145  will touch the smaller contacts of the interface  1130 A (or  1130 B, as the case may be), allowing transfer of electrical energy and/or data between the hanger  1100  to the garment  100 . A battery  900  may be coupled to the other interface  1130 B (or  1130 A, as the case may be), and be charged at the same time. Moreover, additional batteries  900  may be attachably/removably stacked in an arrangement such as the arrangement  100  illustrated in  FIG.  10   , and be charged at the same time. 
     In embodiments, the interfaces  1130 A and  1130 B are such as the interfaces  930 A and  630 A, with circular contacts; and the interface  145  of the garment  100  is then such as the interfaces  745  and  845 , with smaller rectangular contacts. 
       FIG.  12    illustrates selected parts of a combination  1200  that includes a powered garment  100  (such as is described in relation to  FIG.  1   ) or another powered garment (including all feature combinations and feature permutations described and suggested in this document and the attached drawings). The combination  1200  also includes a portable device  1205 , for example, a mobile device such as a smartphone, a tablet, a smart watch, a computer. The portable device  1205  includes a processing system of one or more processors and related/supporting components (memories, I/O, etc.) The portable device  1205  also includes one or more first radios, such as cellular transceivers. WiFi transceivers, and similar Radio Frequency (RF) receivers and/or transmitters. The portable device  1205  also includes a second radio, which would typically (but not necessarily) be an RF radio, e.g., a receiver, a transmitter, or both. The second radio is compatible with the wireless transceiver  150  of the garment  100 . As shown in  FIG.  12   , the portable device  1205  communicates with the garment  100  via a link  1210  between the second radio of the portable device  1205  and the transceiver  150  of the powered garment  100 . For example, the link  1210  may be a Bluetooth® link, possibly a Bluetooth® Low Energy (BLE) link. 
     The portable device receives an “app” (software designed to run on portable/mobile devices, such as smartphones/tablets). The app may be, for example, preloaded on the portable device  1205 , downloaded to the portable device  1205 , transferred to the portable device  1205  through a wired connection, and/or reside in firmware built into or connected to the portable device  1205 . The powered garment  100  includes counterpart software (another app) that is designed to communicate and interact with the app on the portable device  1205 . 
     The two apps, executing by the respective processors of the portable device  1205  and the powered garment  100 , configure the portable device  1205  and the powered garment  100  to establish the link  1210 , and to perform various steps/actions described and illustrated in this document and the attached drawings. Thus, the user/wearer of the powered garment  100  can control the functionality of the powered garment  100  through the portable device  1205 , including the control functions described above in connection with the control button  175 . Exemplary functions that the user can perform through the portable device  1205  include: selecting one or more zones/panels of the garment  100  for subsequent action(s); turning on and off heat in one more zones/panels of the garment  100 ; increasing/decreasing the power level of all or selected zone(s); obtaining a reading of the remaining battery charge level and estimated remaining power-on time; selecting one or more sensor(s) of the garment  100 ; obtaining data from all or selected sensors of the garment  100 ; and others. The functions may also relate to additional powered garments of the user/wearer that are connected to the garment  100 . This will be discussed below. 
       FIG.  13    illustrates selected steps of an exemplary process for performing a user-selected function by a powered garment. 
     At flow point  1301 , the appropriate apps are present in the user mobile device and the garment, the user mobile is powered up, and the electronics in the powered garment are turned on and initialized. 
     In step  1305 , the user activates the app on the mobile device. 
     In step  1310 , the mobile device app and the software in the electronics of the powered garment establish a communication link, such as a Bluetooth® link. 
     In step  1315 , the mobile device app displays to the user of the mobile device a menu or menus of commands. In variants, the app otherwise provides to the user a selection of commands, for example, with pre-recorded instructions. 
     In step  1320 , the app receives the user&#39;s selection; for example, the user touches the selection on the menu, or articulates the selection for the mobile device&#39;s voice recognition software that communicates with the app. 
     In step  1325 , the app generates a command that corresponds to the user&#39;s selection and transmits the command via the link to the powered garment. 
     In step  1330 , the electronics of the powered garment receive the command, through the link and a transceiver of the garment&#39;s electronics. 
     In step  1335 , the processing system of the garment (such as a microprocessor/microcontroller) interprets/recognizes the command and causes the garment to perform the command. For example, it selects one or more zones/panels, turns on or off heat in one more zones/panels of the garment, increases/decreases the power level of the zones/panels, measures or recalls from a memory remaining battery charge reading, selects sensor(s) of the garment, obtains data from the sensor(s). 
     In step  1340 , the electronics of the powered garment send via the link data and/or a confirmation/acknowledgement to the mobile device. For example, the acknowledgement may simply confirm that the command has been received and/or acted on. As another example, the data transmitted may include sensor data. As still another example, the data may include battery state of the powered garment or current power setting of one or more panel(s)/zone(s). 
     In step  1345 , the mobile device receives via the link the data and/or confirmation/acknowledgement from the garment. 
     In step  1350 , the mobile device (executing the app) provides to the user the confirmation/acknowledgement and/or the data and/or some information derived from the data. For example, the mobile device may provide sound and/or haptic indication of the acknowledgment. As another example, the mobile device displays the data or the information. 
     The process may then end at flow point  1399 , and may be repeated as needed or desired. 
       FIG.  14    illustrates selected parts of a combination  1400  that includes three powered garments: a “master garment”  100 M, a first “slave garment”  100 S 1 , and a second slave garment  100 S 2 . Each of these powered garments may include any of the features of the powered garment  100  of  FIGS.  1   / 12 , and other features described throughout this document and illustrated in the attached drawings, including features related to master-slave operation of the combination  1400  described below. 
     The combination  1400  also includes a portable device  1405  such as the mobile device  1205  of  FIG.  12   . A powered garment app is preloaded onto the mobile device  1405 , and each of the powered garments  100 M/ 100 S 1 / 100 S 2  includes counterpart apps designed to communicate with the app on the portable device  1405 . Operational and other details of this embodiment may be identical, analogous, or similar to such details described above in connection with the combination  1200 , with additional features of the apps that relate to master-slave operation. 
     The four apps (on each of the powered garments  100 M/ 100 S 1 / 100 S 2  and the portable device  1405 ), executed by the respective processors of the garments and the mobile device, configure the portable device  1405  and the powered garments  100 M/ 100 S 1 / 100 S 2  to establish a link  1410  between the master garment  100 M and the portable device, and links  1412 / 1414 , between the master garment  100 M and slave garments  100 S 1  and  100 S 2 , respectively. The instructions further configure the portable device  1405  and the garments  100 M/ 100 S 1 / 100 S 2  to perform various steps/actions. Through the established links, the user/wearer of the powered garments  100 M/ 100 S 1 / 100 S 2  can control the functionality of the powered garments through the portable device  1405 , including the control functions described above in connection with the control button  175 . Exemplary functions that the user can perform through the portable device  1405  include: selecting a powered garment from among the garments  100 M/ 100 S 1 / 100 S 2  for subsequent action(s)/commands; selecting one or more zones/panels of the garment  100 M/ 100 S 1 / 100 S 2  for subsequent action(s); turning on and off heat in one more zones/panels of the garments  100 M/ 100 S 1 / 100 S 2 ; increasing/decreasing the power level of all or selected garment(s) or zone(s); reading the remaining battery charge level and estimated remaining power-on time for the garments  100 M/ 100 S 1 / 100 S 2 ; selecting one or more sensor(s) of the garments  100 M/ 100 S 1 / 100 S 2 ; obtaining data from all or the selected sensors of the garments  100 M/ 100 S 1 / 100 S 2 ; and others. 
     As a person skilled in the art would understand after careful perusal of this document and the attached drawings, the configuration  1400  can be reduced to a single slave garment, or extended with additional slave garments connected to the master garment  100 M. 
     Although  FIG.  14    shows the garment  100 M as a jacket and the garments  100 S 1 / 100 S 2  as socks, other powered garments can be substituted for each of these garments. 
     The communication link  1410  can be identical, similar, or analogous to the link  1210  of  FIG.  12   , and can be established in the same, similar, or analogous way. The communication links  1412  and  1414  between the electronic/electrical components of the master garment  100 M and the electronic/electrical components of the slave garments  100 S 1  and  100 S 2  may be wireless and established automatically by the electronic/electrical components of the powered garments, or by the app of the portable device  1405  directing the powered garment  100 M to perform the requisite steps. These garment-to-garment links may also be wired connections. For example, the user may plug into each other corresponding connectors of the powered garments  100 M/ 100 S 1  and/or  100 M/ 100 S 2 . Once the wired connections are made, the links can also be established automatically or with the app of the portable device  1405  directing the process. Either way, each of these connections is established and the master garment  100 M can communicate with the slave garments  100 S 1  and  100 S 2 , for example, transmitting data and/or commands to the slaves, and/or receiving data from the slaves. Moreover, the apps of the garments and the portable device  1405  configure the garments/device so that the portable device  1405  can control the slaves, transmit data to the slaves, and/or receive data from the slaves, with the control commands and the data going through the master  100 M. 
       FIG.  15    illustrates selected parts of a combination  1500  that is similar to the combination  1400  described above. Thus, the garments  100 M/ 100 S 1 / 100 S 2  are identical, similar, or analogous to the identically-designated garments of the combination  1400 ; portable device  1505  may be identical, similar, or analogous to the portable device  1405 ; and connections  1510  and  1512  may be identical, similar, or analogous to, respectively, the connections  1410  and  1412 . Here, however, the second slave garment  100 S 2  is connected to the first slave garment  100 S 1  by connection  1514 . The connection  1514  may be wired or wireless, and otherwise identical, similar, or analogous to the connection  1512 . Additionally, the apps in the powered garments  100 M/ 100 S 1 / 100 S 2  and the portable device  1505  enable the portable device to control and exchange data with the second slave garment  100 S 2 ; the commands and/or data between the portable device  1505  and the second slave garment  100 S 2  in this embodiment flow through both the master garment  100 M and the first slave garment  100 S 1 . 
     As a person skilled in the art would understand after careful perusal of this document and the attached drawings, the configuration  1500  can be extended with additional slave garments so that commands and data between the portable device  1505  and the additional garments flow through the link  1510  and multiple slave-to-slave links. Moreover, additional “primary” slave garments may be connected to the master garment  100 M, and still more “secondary” slave garments may be connected to the master garment  100 M through the primary slave garments. The user can then control the master garment  100 M and all the slaves from the portable device  1505 . 
     In embodiments, power drive to one or more garments (masters and/or slaves), panels, and/or zones is adjusted automatically in response to a sensor indicating a change in the ambient conditions. The sensor may be a temperature sensor placed at or near the outside layer of a garment, and the power drive may be increased or decreased when an abrupt change in the temperature is detected by the software of the garment or of another garment or an app of a mobile device communicating with the garment. An abrupt temperature change may be indicated if the temperature sensor reading indicates that the temperature change rate (TEMP current −TEMP previous )/(TIMEe current −TIME previous ) exceeds a predetermined rate limit. Thus, the system may be configured to decrease or turn off the power drive in response to an ambient temperature increase exceeding the rate limit. Similarly, the system may be configured to increase or turn on the power drive in response to the absolute value of the ambient temperature decrease exceeding the rate limit; or in response to the absolute value of the ambient temperature decrease exceeding the rate limit and the ambient temperature being below a predetermined “cold” temperature. In embodiments, an analogous method is employed with thermal flow agents, to increase/decrease heat provided to one or more garments of a user, and/or to increase/decrease cooling provided to the one or more garments. 
     A garment carrier/bag or a closet may incorporate any of the features of the hangers discussed throughout this document, and provide the same or similar/analogous functionality. The features may be included in a hanger built into such a garment carrier/bag/closet, or provided by the carrier/bag/closet without reliance on the hanger. As an example.  FIG.  16    is a front perspective view illustrating selected features of a garment travel bag  1600  with a built-in garment charger and data interface(s) (wired or wireless). The garment travel bag  1600  includes a bag body  1655 , which may be made, for example, of vinyl, leather, textile, or another material used for such garment storage devices. The bag body  1655  includes a top  1656 , a first (right) side  1657 , and a front  1658 . There may also be other external areas, to wit, a back, a bottom, a second/left side, but these are not visible in the Figure. A zipper or another length fastener  1660  is located vertically on the front  1658  and allows inserting garments into, and removing garments from, the bag body  1655 . A top opening  1662  may be provided to facilitate the use of hanger(s) (whether conventional or as described in this document) with the garment travel bag  1600 . 
     A pair of enclosure charging interfaces  1665 A/ 1665 B are built into, or attachable to, the garment travel bag  1600 , for coupling to the garment charging interfaces of the garment(s) inside the bag body  1655 . The enclosure charging interfaces  1665 A/ 1665 B may be identical, analogous, or similar to the hanger charging interfaces that have already been discussed at some length, including relatively-low frequency (e.g., &lt;100 KHz) inductive charging interfaces, contact interfaces such as the interfaces  630 A/ 630 B with circular and smaller rectangular contacts, pluggable connectors, and induction exciters operating at radio frequencies. In examples, the enclosure charging interfaces  1665 A/ 1665 B may not be visible from outside. There may be just a single enclosure charging interface, or more than two such enclosure charging interfaces. Moreover, the one or more enclosure charging interfaces may be located in various positions and on different sides (left, right, front, rear, top, bottom) of the garment travel bag  1600 , and need not be circular but fabricated in different shapes. A power cord  1672  protrudes through an opening  1670 , and has a plug  1673  on its end, for connecting to the power grid and providing electrical power to the garment travel bag  1600  and for charging the garments inside the garment travel bag  1600 . The garment travel bag  1600  also includes electronics, which are not visible in the Figure. As has already been mentioned, the electronics may provide garment charging capability, and communication transceivers (e.g., cellular transceivers, Bluetooth® transceivers, WiFi transceivers, other RF transceivers, wired transceivers such as Ethernet) for connecting to the garments in/near the garment travel bag  1650 , and/or connecting to other networks, including connecting directly or indirectly to wide area networks.
