The present disclosure relates to an apparatus for and a method of recharging a smart-charging clothing in a powered enclosure.
Wearable devices are designed, fabricated, and assembled with disparate shapes, sizes, and structures by a variety of suppliers. They are often operated with DC power from a battery. However, the battery is often small, compact, and light in weight so as to accommodate constraints of the wearable devices. Thus, the battery needs to be recharged after a period of use.
The recharger for the battery is usually customized for the particular wearable device. As a result, a user has to purchase multiple rechargers. In one instance, the user must carry around the appropriate recharger for use as needed with each wearable device as the battery becomes completely depleted.
In another instance, the user must take the wearable device to where the appropriate recharger is stored and recharge the wearable device on a schedule before the battery becomes depleted. Both instances pose a recurring logistical challenge especially when the recharger is larger and heavier than the wearable device itself.
As the wearable devices become smaller in size and greater in number, the user must invest ever more resources in money and time to keep the wearable devices operating in an optimal condition.
Thus, it would be desirable to disclose an apparatus and method that addresses these enumerated issues in a timely and cost effective manner. In particular, the various embodiments of the claimed disclosure may be usefully applied to recharge various wearable devices as they continue to proliferate in the future.
To facilitate understanding, identical reference numerals have been used, wherever possible, to designate identical elements that are common to the figures. The drawings are not to scale and the relative dimensions of various elements in the drawings are depicted schematically and not necessarily to scale.
The techniques of the present disclosure may readily be understood by considering the following detailed description in conjunction with the accompanying drawings, in which:
Before the present disclosure is described in detail, it is to be understood that, unless otherwise indicated, this disclosure is not limited to specific procedures or articles, whether described or not.
It is further to be understood that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the scope of the present disclosure.
It must be noted that as used herein and in the claims, the singular forms “a,” and “the” include plural referents unless the context clearly dictates otherwise. Thus, for example, reference to “an enclosure” also includes two or more enclosures, and so forth.
Where a range of values is provided, it is understood that each intervening value, to the tenth of the unit of the lower limit unless the context clearly dictates otherwise, between the upper and lower limit of that range, and any other stated or intervening value in that stated range, is encompassed within the disclosure. The upper and lower limits of these smaller ranges may independently be included in the smaller ranges, and are also encompassed within the disclosure, subject to any specifically excluded limit in the stated range. Where the stated range includes one or both of the limits, ranges excluding either or both of those included limits are also included in the disclosure. The term “about” generally refers to ±10% of a stated value.
Methods of and apparatuses for recharging smart-charging clothing 500 are disclosed herein. Embodiments of methods of the present disclosure will be described followed by embodiments of apparatuses of the present disclosure.
A method of the present disclosure includes a sequence of inserting, storing, connecting, recharging, and removing one or more smart-charging clothing 500 from an enclosure 100 of the claimed disclosure, as shown in
A recharging enclosure 100 may recharge a smart-charging clothing 500, as shown in
The smart-charging clothing 500 may include a communication device in some embodiments. The smart-charging clothing 500 may include a time tracking and display device, such as a watch, timer, stop-watch, or alarm. The smart-charging clothing 500 may include a biometric device, such as a health monitor, health alert, or health alarm. The smart-charging clothing 500 may include an information, or data, acquisition and playback device, such as a personal recorder, or personal digital assistant.
First, the smart-charging clothing 500 is inserted into a holder 410, 420, 430, 440, 450, 460, as shown in Block 110 of
Various holders 410, 420, 430, 440, 450, 460 are shown in
In various embodiments of the present disclosure, the holder 410, 420, 430, 440, 450, 460 may include a hanger 411 as shown in
Second, the holder 410, 420, 430, 440, 450, 460 is stored in an enclosure 100, as shown in Block 120 of
In various embodiments of the present disclosure, the recharging interface 310, 320 may include a rod as shown in
Third, the smart-charging clothing 500 is connected to the recharging interface 310, 320, as shown in Block 130 of
The connecting of smart-charging clothing 500 via holder 410 to the recharging interfaces 310, 320 may be through (direct) physical contact such as shown in
The paddles or contacts in smart-charging clothing 500 may be protected from oxygen or water in the atmosphere to prevent corrosion. Charging through physical contact may be simpler, cheaper, and faster than through wireless contact. However, wireless contact may be more durable, and more reliable compared to physical contact.
Fourth, the smart-charging clothing 500 are recharged, as shown in Block 140. Smart-charging clothing 500 have different power requirements depending on specific consumer electronic device functionality. Laptop computer functionality requires about 65-90 watts. Tablet computer functionality requires about 25-30 watts. However, other wearable device functionality may only require about 2-10 watts.
Recharging the smart-charging clothing 500 may be accomplished through contact recharging or non-contact recharging. The non-contact recharging may be through inductance, or resonance, or a combination of inductance and resonance.
Inductive charging may result in higher resistive heating and thus lower efficiency and slower recharging. However, transfer losses for inductive charging may be decreased by using an ultra-thin coil. Furthermore, inductive charging may be improved by optimizing power management in the drive electronics. In an embodiment of the present disclosure, high-frequency induction charging may have an efficiency of 90-95%.
In an embodiment of the present disclosure, a secondary (pick up or receiver) induction coil in the holder 410, 420, 430, 440, 450, 460 is aligned and placed in proximity with a primary (charger or sender or transmission) induction coil in the recharging interface 310, 320. A power panel may supply AC current, such as through an inverter, to the primary coil in the recharging interface 310, 320. The two induction coils precisely located (aligned) in proximity may combine to form an electrical transformer. The primary coil may be electrically charged to generate a magnetic field that induces AC current in the secondary coil in the holder 410, 420, 430, 440, 450, 460 to be converted to DC current, such as through a rectifier, to recharge a battery pack in the smart-charging clothing 500.
In an embodiment of the present disclosure, the primary induction coil in the recharging interface 310, 320 may be movable by being mounted onto an actuator, such as an arm fixture, that may pivot, elevate, turn, and rotate. In another embodiment of the present disclosure, the secondary coil in the holder 410, 420, 430, 440, 450, 460 may be fabricated from silver-plated copper or aluminum to reduce weight and decrease resistance due to a skin effect.
In an embodiment of the present disclosure, inductive charging may use a frequency of 120-250 kHz. In an embodiment of the present disclosure, coil-to-coil spacing may be about 5-10 cm.
Inductive charging may be improved by using a higher frequency. In an embodiment of the present disclosure, a frequency of 6.78 MHz may be used. In an embodiment of the present disclosure, a frequency of 13.56 MHz may be used. Inductive recharging at higher frequency may go through obstructions without being impeded. In an embodiment of the present disclosure, high-frequency induction charging may have an efficiency of 70-75%. In an embodiment of the present disclosure, high-frequency induction charging may have an efficiency of 80-85%. In an embodiment of the present disclosure, coil-to-coil spacing may be 30-50 cm.
Resonant inductive coupling may be used to allow a greater intervening space (separation or gap) between the primary coil in the recharging interface 310, 320 and the secondary coil in the holder 410, 420, 430, 440, 450, 460. In an embodiment of the present disclosure, a curved coil and capacitive plates may be used to add resonance to the inductance. To achieve resonant coupling, each coil is capacitively loaded so as to form an LC circuit. In an embodiment of the present disclosure, the spacing between the primary coil in the recharging interface 310, 320 and the secondary coil in the holder 410, 420, 430, 440, 450, 460 may be 1-2 meters. In another embodiment of the present disclosure, the spacing between the primary coil in the recharging interface 310, 320 and the secondary coil in the holder 410, 420, 430, 440, 450, 460 may be 3-5 meters.
Fifth, the holder 410, 420, 430, 440, 450, 460 may be removed from the enclosure 100, as shown in Block 150 of
In an embodiment of the present disclosure, the enclosure 100 may include a closet, a cupboard, or a box in a form of dwelling, such as a room, an apartment, or a house.
