[0001] The present disclosure relates to the field of anti-theft and charging devices.
More particularly, the present disclosure relates to a compact and power efficient circuit for
enabling anti-theft and charging, which can be configured with various items to protect them
from theft and loss, and also facilitate charging of various devices.
BACKGROUND
[0002] Background description includes information that may be useful in
understanding the present invention. It is not an admission that any of the information provided
herein is prior art or relevant to the presently claimed invention, or that any publication
specifically or implicitly referenced is prior art.
[0003] Loss and theft of day to day items such as cards, keys, mobile phones, wallets,
bags and other belongings are very common these days. All of us at certain point of time have
witnessed loss or theft of our important as well as daily use items. Sometimes we lose them or
leave them carelessly at unrecognizable places, or some time these items gets stolen by
someone.
[0004] With the continuous development of technology, mobile computing devices
such as mobile phone, laptops, tablet and wearable devices have become more and more multifunctional and expensive. People rely on these devices for communication as well as for storing
their important data. When people lose their mobile computing devices, it causes them a lot of
inconvenience and data loss.
[0005] Some of these mobile computing devices have unique IMEI number which may
help track the lost or stolen devices. However, such process of tracking mobile computing
devices is time taking, with very less success rate as there are chances that the thief might
completely erase the data to restrict tracking of the device. In worst case the thief might destroy
the device and/or sell the mobile computing device in black market. In many cases, these lost
devices are not fund by anyone, as a result, such available tracking technologies will not work
unless someone switches on the device. In both the cases, it becomes very difficult for the users
to track their lost or stolen devices.
[0006] Further, such tracking technology can only be implemented in mobile
computing devices, and that too only up to an extent. However, there are no such tracking
3
technology available, which can be configured with day to day items such as cards, keys,
mobile phones, wallets, bags and other belongings, to track them when lost or get stolen.
[0007] In addition, regular use of these mobile computing devices leads to faster
drainage of their battery. It becomes difficult for people to charge stop and charge their mobile
computing devices while they are working outside or travelling.
[0008] Furthermore, with increased crime rate in the society it has become tough for
people, especially women and children, to go outside and travel alone. Various alarm and
beacon devices are available in market to send alert and SOS signals. However, they are large,
thereby making it difficult to carry along with other general items such as wallet, purse and
mobile phones. Also, these available alarm and beacon deices are easily recognizable by
criminals.
[0009] Therefore, there is a need in the art for a compact and power efficient circuit for
enabling anti-theft and charging, which can be configured with various day to day items as well
as mobile computing devices to protect them from theft and loss, and to facilitate charging of
the mobile computing devices, and which can also act as a beacon module to send alert and
SOS signals.
