EXAMPLES

(45) The embodiments of the present invention can be better understood by reference to the following examples which are offered by way of illustration. The present invention is not limited to the examples given herein.

Example 1

(46) First Use

(47) As illustrated in FIG. 1, upon first use the system asks the user to optionally enter information about himself/herself (UB). In other words, the system is able to learn by itself without the optional input by the user upon first use. From this information, the system will then perform an FSU, enabling intelligent automation before the user has even used the device himself/herself. However, if the user has used the system before in another article of clothing, he/she may retrieve his/her UB and LD directly from the servers. Certain authentication procedure may be implemented to authenticate the user's identity by the server or by the local data storage in order to let the system to retrieve his/her personal information therefrom before operation.

(48) Normal Operation

(49) As illustrated in FIG. 2, in normal operation, the user may alter the US directly on the garment via user input through input means such as, but not limited to, buttons, switches, knobs, or multi-touch screen on a display panel of the garment, or on a smartphone, tablet, website, wearable hardware and/or server that is connected to the garment via wired or wireless means. Upon such a change in the US, the ALD is triggered. Any subsequent action before the ALD has elapsed will restart ALD. Once the ALD has elapsed, an ALA will be performed. This process ensures that only the final US set by the user are registered to the corresponding DP in the LD.

(50) Conversely, when the CD changes the PLD is triggered and the CD is stored as a temporary DP (TDP). Since sensor data may fluctuate every fraction of a second, each fluctuation will be compared to the TDP and if it exceeds the RT, the PLD will be restarted, reducing inaccurate learnings. Once the PLD elapses, a PLA is performed. If an ALA is triggered at any time during this process, the PLD and PLA will be cancelled, so that the user's preferences are accurately reflected in the LD.

(51) At the same time when the CD changes, the system will try to perform an IA. In order to do this, it searches through the LD for the closest DP to the CD and factor in weights assigned by PT and SUT, as well as conditions specified in MD. If this match is higher than the RT, the settings will be set to the US corresponding to the matched DP.

Example 2

(52) Below is a working example of the present system in a smart garment:

(53) FIG. 3 shows an embodiment of the present system automating a smart garment for heating and/or cooling. The smart garment (300), for instance, a zip top or a jacket, includes: a plurality of body sensors (301), such as heart beat rate/pressure sensor, body temperature sensors, body humidity sensors, as well as environmental sensors such as external temperature and external humidity; a number of knobs and/or buttons located on the garment surface (302), such as power On/Off, power level controls and area controls; an electronic printed circuit board (PCB) (303), with an integrated circuit (IC), memory, other components for data processing, storage, and wireless communication (such as Wi-Fi and/or Bluetooth). This PCB may also incorporate sensors such as an accelerometer, a GPS, and a Wi-Fi to NFC (Near field communication) chip or a Bluetooth to NFC chip (306); a plurality of pads (305) as the output for production and/or absorption of heat and/or cold; a plurality of power and signal wires/cables (307), embedded in the garment and/or attached to the fabrics, and connecting the various electrical elements, as well as their corresponding connectors; an external, and/or built in, power source (304), such as a power bank.

(54) The present garment can be connected wirelessly to a smartphone (320), or other smart device such as a smartwatch, tablet or other device, which provides an application layer. This layer includes data processing, as well as a user interface, for the user's profile management, consultation of data, as well as data entry. In particular, the user may enter his commands directly from the application, such as On/Off, power level controls (change power to heating and cooling levels) and area controls (heating and cooling area activation and controls). The mobile application can also fetch data from the phone (or other smart device such as a smartwatch, tablet or other device), in-built sensors, such as accelerometers, gyroscope, magnetometer, and GPS, as well as data from the user's past history, as well as data from third parties on the cloud, such as local wind speed or climactic and weather conditions, as well as data from the system's servers, for instance, data correlated from other users.

(55) An example of the garment integrated with the present system is shown in FIG. 4, while the close-up view of the optional user input panel as a form of knobs or buttons attached onto the garment is indicated by a block arrow in FIG. 5 and a rear view of the garment where the heating and/or cooling pad as an output device of the system is embedded into the garment is indicated by block arrows in FIG. 6. They are not intended to limit the present invention to suit a particular type of garment or configuration but only to show that the present system is integral to any type of garment including but not limited to a zip-top as shown in FIG. 4.

(56) In an event that a user uses the present garment for skiing, if the user is a first-time user, he/she is asked by the system to input his/her own personal data such as weight, height, age, health conditions, etc., into the system. He/she can manually input location or the GPS which is optionally embedded into the system is activated automatically once the system is started to detect his/her location before the system enters into normal operation stage. Without the user's input, the present garment is able to learn by itself from similar data from a third-party device stored in a database. For security concern, he/she may be asked to provide a user login details for future access to or retrieval of data from local memory or data storage or from a remote server. If the user is a return user, the user is asked to provide his/her latest login details for registering his/her own data into the garment from the server (340). Once the server recognizes the login details input by a return user, the garment will download the previously stored user data from the server via a wireless communication network, or will retrieve the user data from the local memory or data storage of the garment. In any case, the garment is fetched by the server (340) or a third-party device such as a third sensor (310) or third-party data center (330) with data from similar user of a specific instance, for example, under this instance, is a ski user with comparable personal data. The user may also be asked to input his/her preference of heating and/or cooling settings in the garment, e.g., keep the garment at certain temperature range when skiing; which part of the pads are activated; what power level is at certain part of the garment, etc. Alternatively, the system may be pre-set with the conditions for the heating and/or cooling output for the garment according to the data from similar user if the user does not provide such information at the data verification stage. The user, however, is allowed to change his/her user setting anytime during the operation stage of the garment.

(57) After the data verification stage, the user can use the garment at its operation mode. During the normal operation stage, the garment is basically responsive to the sensor data from time to time. If at one time point the corresponding sensor data, e.g., temperature, pressure, humidity, wind speed, etc., detected by the sensors is over a reference difference between the instant record and the previous record at the previous time point, the system will automatically change the user setting and execute the corresponding output, e.g., increase or decrease the temperature of the pad in the garment, after certain period of time. In case where there is another record of sensor data which exceeds the reference value during that period of time, the count-down of a new cycle will start until there is no interruption or change of sensor data detected during a cycle. The time interval of each cycle can be adjusted according to user's preference, but the system is capable to detect fluctuation of sensor data in the degree of every millisecond, and the count-down of each cycle is achieved by a timer in the system.

(58) Apart from the change in sensor data from time to time, the user may interrupt the cycle by inputting user setting with respect to his/her preferred temperature of the pad in the garment. The garment is configured to take user's preference as first priority over the change in sensor data in the output setting. That is, when the user feels like he/she need more warmth or cold in certain part of the body from the garment during skiing, he/she may adjust the pad temperature via a mobile application wirelessly connected to the garment or other means such as a button or switch or some physical means attached to or on the garment, such user's instruction to increase the temperature of the pad in the garment will take priority over the change of the setting due to the sensor data difference exceeding a reference threshold.

(59) The data whichever received from the sensors or input by the users are stored in the local data storage of the system. Comparison and matching of the data so received and stored in the system of the garment with other comparative data from similar user or from a server are also performed almost concurrently or subsequently to each data collection cycle by the system to ensure the data accuracy and the consistency between the output and the user's preference at a specific instance.

(60) The data stored in the local memory or data storage of the garment can be used for the next time skiing activity of similar kind and conditions by the same user. Such data can also be shared with similar users of the same model of garment and/or stored in the server as a database. A matrix of data sets including both sensor data and body characteristics of a particular user is preferably stored in the database of the server for analysis and optimization of the system for different applications.

Example 3

(61) FIG. 7 shows one of the preferred embodiments of the smart garment (100) incorporated with the power management unit of the present invention, which is a zip-top. However, it should be understood that the smart garment of the present invention is not limited to zip-top but can also include other types of clothing or garment such as jacket, footwear, headgear, any form of gear worn by or attached to a part of the user's body, and any types of accessories. In addition, the output of the power management unit, i.e., the temperature control element, is only an example of the output which can be controlled by the power management unit, but it should also be understood that the type of output is not limited to the temperature control element but can also include heating, cooling, massaging, vibrations, and/or any combination thereof. In FIG. 7, the power circuit board (PCB) (106) of the power management unit is hidden in the smart garment and connected with two buttons (103, 104) configured at the waist end of one of the sleeves of the smart garment through the wire or cable (101) hidden in the smart garment in order to control the power on/off of the power management unit and/or the temperature of the temperature control element according to the time duration of the pressure applied thereon by the users.

(62) FIG. 8A shows an extendible wire or cable (101) which has been connected to the power management unit at one end and is open for connecting to a power bank (102) at another end. The wire or cable (101) can be configured with a USB-type port or alike such as micro-USB, or any other types of port that are available for establishing electric connection between two components. For carrying the power bank (102) which is connected to the power management unit and for hiding the extendible wire or cable (101), the smart garment can be configured to have one or more power bank pockets (112), wherein said extendible wire or cable (101) can be extended from a hole in the power bank pocket (112) to a distance that is capable of connecting with the power bank (102). Said power bank pocket (112) can be easily sealed or opened via any suitable mechanism such as zipper, Velcro, etc.

(63) FIG. 8B shows the wire or cable as shown in FIG. 8A be connected to the power bank at another end. It is possible that the connection between the power management unit and the power bank (102) is wireless, for instance, Qi induction, or the power is supplied from other electric/electronic component of the smart textile, through a power network or from any external power source. FIGS. 11A and 11B show the smart garment incorporated with the power management unit according to another embodiment of the present invention, wherein the connection between said power management unit and the power bank (102) comprises a wireless connection between the power bank (102) and the temperature control element (105), thereby wires or cables configured to connect the power bank or other components with the power management unit in the smart garment can be avoided.

(64) FIG. 9A shows two of the buttons (103, 104) disposed close to the wrist end of one of the sleeves of the smart textile. The two buttons (103, 104) are not necessarily disposed next to each other on the same wrist end of the sleeve of the smart textile and each of them can include one or more functions. In this example, the two buttons (103, 104) enclose two respective LEDs (not shown in FIG. 9A). Part of the surface of the button is transparent to the light emitted from the LED enclosed therein. The respective LED is not necessarily enclosed in the button. Other form of physical association between the button and the respective LED is also applicable in the present invention. In a preferred embodiment of the present invention, one of the two buttons (103) is configured to be on “blinking” mode at default setting when the power management unit is just connected to the power bank. The button on “blinking” mode can be readily changed for controlling power on/off of the power management unit and/or selecting temperature of the temperature control element in terms of the duration of pressure exerted thereon by the user. In this example, a pressure sensor is incorporated into the button (103) in order to sense the pressure exerted by the user's finger. In another embodiment, it is possible to have only one LED which provides different indications with a range of colors, each having still and blinking signal(s). In other embodiments, it is also possible that other types of sensor or sensing mechanism is incorporated for sensing the user's command, for example, if the power on/off and/or temperature selection and/or operation mode selection is controlled through a touch screen control panel, the virtual buttons on the touch screen may be incorporated with a temperature sensor underneath the display of the touch screen. Since the power management unit is electrically connected to the temperature control element, controlling the power on/off of the power management unit is capable of controlling the power on/off of the temperature control element. However, it is possible that the power on/off of the temperature control element is under the control of a separate circuit which power is controlled by one of the two buttons. To control and/or select different adjustable parameters of the output using one of the buttons, an illustrative example is presented in FIG. 12 which will be described further in the following example. For example, as shown in FIG. 9A, one of the two buttons can be pressed and/or held by the user in order to control and/or select different adjustable parameters. In this example, if the user presses the operation mode control button (104) once, he/she can adjust the level within one particular mode. In another example, if he/she presses the button and holds it for a while, for example, for 5 seconds, the operation mode will be switched from one mode to another. After he/she releases the button, he/she can press again to adjust the level within another mode.

(65) FIG. 9B illustrates another example of the arrangement of the functions that the buttons can control, select, and/or adjust. In this example, the power on/off and the operation mode selection are controlled/selected by the same button (103a) while the level of the temperature of the temperature control element is adjusted by another button (104a). It is possible that one button or knot is configured to be used to control, adjust and/or select the power on/off, operation mode, and adjustable level of the output element.

(66) FIG. 10 shows the back side of the smart garment as shown in FIG. 7 where the temperature control element, in a form of two heating/cooling pads (105), is disposed. Once the button (104) for selecting and adjusting the operation mode and its level of operation is pressed, the temperature control element starts to execute the instructions according to the mode and corresponding level of operation as selected, unless the button (104) is being held for a sufficiently long period of time, e.g., 5 to 10 seconds. In one embodiment, when one pad is activated, the output power is sent to that pad; when two pads are activated, the output power is shared among the two pads in such a way that one pad receives the full power for a short time interval and then the other pad receives the full power for another short time interval under the power alternation. In another embodiment, the pads receive the power at the same time without alternation, depending on the amperage of the power bank or source. The output power in that another embodiment is split and allocated among the pads at equal or different power level, depending on the power demand of a particular pad.

(67) FIG. 12 shows the steps of how to initiate and operate the power management unit in the smart textile of the present invention. First of all, the power management unit is connected to a power source, e.g., a power bank, through a wire or cable (s201). After connecting the power management unit to the power bank, a blue LED blinks every 10 seconds (s202). An intervening event of the “blinking” mode of the blue LED is a long-press action on the button enclosing the blue LED by the user (s203). A sensor, e.g., a pressure sensor (not shown in figures), being incorporated into the button enclosing the blue LED may be used to sense the long-press action by the user such that it decides whether to switch on another circuit controlling the temperature control element or not. Depending on the user's or manufacturer's setting, the threshold duration for the long-press action to switch on another circuit varies, e.g., between 5 and 10 seconds. If the user presses the button enclosing the blue LED for sufficiently long time reaching the threshold, the circuit controlling the temperature control element will be switched on. Otherwise, the blue LED will remain in “blinking” mode, representing the smart textile is in ready-to-use state only. Another LED for signaling the operation mode of the temperature control element is switch on and stays as “on” mode according to the default setting after the blue LED is turned into “on” mode because of the long-press action by the user reaching the threshold duration (s204). Simultaneously, the circuit controlling the temperature control element is also switched on and becomes available to control the temperature control element embedded into or attached onto the smart textile to heat up or cool down (s209), subject to other sensing mechanism(s) of the smart textile. Said another LED can be enclosed in another button which allows the user to select the operation mode and/or adjust the level of the selected mode (s205). After selecting the desired operation mode and level of operation, said another LED is on for 10 seconds (s206) then it blinks every 10 seconds (s207) until a gyroscope sensor embedded into or attached onto the wrist end of one of the sleeves of the smart textile where the buttons are disposed senses a rotational motion of the user's wrist along any of the 3-D planes (s208). Said another LED will return to the default setting, i.e., “on” mode (s204), until it is intervened by another selection of operation mode and/or adjustment of operation level through pressing and/or holding said another button by the user. In the circuit controlling the temperature control element, after the circuit is switched on (s209), the temperature control element will be operated according to the selection of operation mode and/or adjustment of operation level made by the user (s205). The heating or cooling action of the temperature control element is paused when the surface temperature reaches the temperature level selected by the user or the temperature level corrected by other sensing mechanism(s) (s210). The circuit controlling the temperature control element will be switched off (s212) if the user holds said another button for sufficiently long duration when he/she is selecting the operation mode and/or adjusting the operation level, e.g., for 5 to 10 seconds (s211). If the circuit controlling the temperature control element is switched off, said another LED will be switched off and the blue LED will blink every 10 seconds again, meaning that the smart textile returns to ready-to-use state. The foregoing mechanisms are executed in at least a chip of the PCB of the power management unit.
