Field of Invention:
The present embodiment relates to powering solution for mobiles and other portable electronic devices such as laptops, and more particularly to a universal power bridge that can control and regulate power supply to such instruments.
Background of Invention:
In recent years, use of portable electronics such as mobile phones, laptops and like has substantially increased in every walk of life. Almost all of these devices run on rechargeable batteries, and more particularly on lithium-ion batteries. Accordingly, they need to be charged at appropriate times for appropriate duration to elongate their life as well as battery life. Most people choose to charge their devices overnight in order to have full battery the next day before leaving for work or travel etc.
Usually, especially at night, after plugging the device in for charging their batteries, the batteries or devices are often left on charging and removed from main supply only in morning. This may prove hazardous to the device as well as to the user, and also shortens the battery life. Moreover, in situations such as sudden high voltage or load, the device may burn. In such scenario, conventional chargers afford no safety to the devices.
Accordingly, there is need to develop a device that determines the power needs of an electronic device and regulates the charging automatically.

Before describing the detailed embodiments that are in accordance with the present disclosure, it should be observed that the embodiment reside primarily in combinations arrangement of the system according to an embodiment herein and as exemplified in FIG. 1 through FIG. 2
Any embodiment described herein is not necessarily to be construed as preferred or advantageous over other embodiment. All of the embodiment described in this detailed description are illustrative, and provided to enable persons skilled in the art to make or use the disclosure and not to limit the scope of the disclosure, which is defined by the claims.
It will be apparent to those skilled in the art that various modifications and variations can be made to the present embodiment without departing from the spirit and scope of the invention. Thus, it is intended that the present embodiment and disclosure cover the modifications and variations of this
4

invention provided they come within the scope of the appended claims and their equivalents.
In the following description, for the purpose of explanation, numerous specific details are set forth in order to provide a thorough understanding of the arrangement of the system according to an embodiment herein. It will be apparent, however, to one skilled in the art, that the present embodiment can be practiced without these specific details. In other instances, structures are shown in block diagram form only in order to avoid obscuring the present invention.
As mentioned, there is a need to develop a device that determines the power needs of an electronic device and regulates the charging automatically, the embodiment herein relate to a universal power bridge, which is a power supply controlling and regulating device.
Fig. 1 illustrates an inside view of a power bridge, according to an embodiment herein. The power bridge may also be termed as a power supply controlling and regulating device. The power bridge 100 includes a time adjustment button 102, a mode selector 104, a display 106, a circuit and microcontroller chamber 108, a relay and Wifi chamber 110, a number of USB ports 112, an extension cord 114, and a female socket 116. The power bridge 100 may be moulded as shown in Figure 1. However, it will be obvious to a person skilled in the art to alter the position of the various components while retaining the same internal connection between various components and the resultant function. The power bridge as illustrated in Figure, accordingly, is an exemplary illustration. The time adjustment button 102 and the mode selection button 104 are connected with the display 106, and their status or selection may be displayed on the display 106. The circuit and the microcontroller chamber 108 is connected to
5

the display 106. The circuit and the microcontroller chamber 108 is further connected to the relay and wifi chamber 110. The microcontroller chamber 108 includes a microcontroller, which can be programmed to determine and work according to the working duration, charging duration, charging status etc. The relay chamber 110 includes a relay or a multi-relay. The relay and wifi chamber 110 also houses a number of USB ports 112. In a preferred embodiment, there are two USB ports. The relay and wifi chamber 112 is connected to the extension cord 114 that has a female socket 116 to receive a plug of a portable electronic device to be charged. In a preferred embodiment, the relay and wifi chamber 112 has 6 relays, out of which 3 relays are connected to the extension cord 114. Alternatively, the portable electronic device may be charged directly through the USB ports 112 that are connected with the relays. The portable devices that may be charged using the power bridge 100 may include mobiles, smartphones, tablet, laptops, electronic book readers and like.
Fig. 2 illustrates a rear view of the power bridge of Fig. 1, according to an embodiment herein. The power bridge 100 further includes a time ON/OFF switch 202, a socket selector 204, and a male pin 206 to the socket.
This power bridge 100 may be controlled to be switched ON for particular duration as desired and then automatically switched OFF. The power bridge 100 may be controlled through mobile phones through mobile applications or manually. For manual operation, the time adjustment button 102 may be used to assign or pre-determine a charging duration and after the duration has passed, the circuit and microcontroller chamber disconnects the power supply to the portable electronic device. In an embodiment, the power bridge is used for regulating and controlling power supply of electrical appliances such as mixer, grinder, mosquito liquidators, bucket water heaters, rechargeable
6

devices such as trimmers, shavers, decorative lights etc. The power bridge 100 may be operated remotely through a mobile application or a remote.
This power bridge 100 thus acts as a bridge between the portable electronic device/electrical appliances and the normal AC power supply commercially available. The expandable female power socket 116 may be a 3 pin female socket that allows external devices to be connected. The display 106 helps the user to visualize the time of operation of the device, as fixed or determined, using the mode selection button 10. The mode selection button 104 may have settings for cyclic operations such as for a mixer, which has to start for 1/4 a minute and halt and again run for next 1/4 minute or for a grinder, which usually run for 15 minutes and require a pause, and again runs for 15 minutes. The time adjustment button 102 also assists to select a time span as well as the cycle of operation of the socket 116 to supply power to the connected device.
The USB ports 112 are used for plugging in mobile phone, tablet computers and any Li-ion based rechargeable devices for charging.
The socket selector button 204 enables the user to select USB ports for use so that the power bridge may receive data of the battery's charging status. Any device plugged in to the USB ports 204 is monitored for the charging process. The power bridge may be programmed to automatically disconnect the power supply when the battery charge level of the device reaches 80%. In an embodiment, the battery charge level for such purposes may be determined by the user. The Wi-Fi module may be connected to a mobile application meant to operate the power bridge 100 from remote location. The power bridge 100 may also be connected to the mobile application via Bluetooth or Wi-Fi. The battery charging level to determine the time span and disconnecting power supply may also be set up using the mobile application.

Further, commercially, AC power supplies are used for charging devices and for operating other electrical appliances. For using the microcontroller, which needs DC power supply; a convertor to convert AC to DC 5V supply is added. All ports, Sockets, Wi-Fi, Bluetooth module and buttons communicate with the microcontroller through a multi-relay that enables communication with electronic devices and electrical appliances through the mobile application simultaneously. The socket selector 204 is used to determine or assigns which socket can be selected or activated for charging. The mode selector button 104 is used to determine the mode of usage of the power bridge 100.
