The present invention relates to the field of estimating relative direction between two or more electronic devices, more specifically, it focuses on the field of estimating relative direction using distance and orientation parameters.
Children, pets, people that require supervision (elderly persons, prisoners etc) and important or valuable objects may be lost and apart from their intended location either by disorientation, distraction, theft or kidnapping. With the increased concern regarding the above there is a need for relatable and quick methods for tracking some or all of the above that will appropriately alert the relevant persons or authorities.
Conventional methods and systems utilize an expensive and complex dedicated system that in most cases does not allow the average person, especially young children, pet and elderly to use any such system for day to day uses, and usually are limited to expensive devices and a like.

These devices require high-energy consumption, are expensive and do not have the same accuracy everywhere (for example, indoor or in a bad-reception area).
There is therefore a long unmet need for a system that will be able to give an estimation of a relative direction and location of a person, which is out of a specific range.

In order to understand the invention and to see how it may be implemented in practice, a few preferred embodiments will now be described, by way of non-limiting example only, with reference to be accompanying drawings, in which:
The following description is provided so as to enable any person skilled in the art to make use of the invention and sets forth examples contemplated by the inventor of carrying out this invention. Various modifications, however, will remain apparent to those skilled in the art, since the generic principles of the present invention have been defined specifically. Also, it is to be understood that the phraseology and terminology employed herein is for the purpose of description and should not be regarded as limiting.
The term “server”, refers hereinafter to any physical hardware device configured to communicate with electronic devices and store data. It may also relate to different disconnected hardware devices at different locations, these hardware devices maybe in partial or full communication with each other.
The term “computer readable medium (CRM)”, refers hereinafter to any non-transitory medium that is capable of storing or encoding a sequence of instructions for execution by a computer and that cause the computer to perform any one of the methodologies of the present invention, it includes, but is not limited to, solid-state memories, optical and magnetic disks, and carrier wave signals.
The term “Magnetometer”, refers hereafter to any scientific instrument that measure the strength and/or direction of a magnetic field. Typically, magnetometers measure a magnetic field or flux density in metric units of gauss (G) or the international system (IS) unit tesla (T). A non limiting example for a magnetometer is “Overhauser magnetometer” which incorporates an electron-rich liquid combined with hydrogen and subjected to a radio frequency (RF) signal. In the presence of this signal, the unbound electrons in the liquid transfer to the protons of the hydrogen nuclei; the resultant energy transfer polarizes the liquid. The precession frequency is linear with the magnetic flux density and thus can be used to measure it.
The term “sub-giga RF” refers hereinafter to radio frequency below 1000 KHz.
The term “Dash7” refers hereinafter to an open source wireless sensor networking standard for wireless sensor networking.
The term “Bluetooth” refers hereinafter to a wireless technology standard for exchanging data over short distances (using short-wavelength radio transmissions in the ISM band from 2400-2480 MHz) from fixed and mobile devices.
The term “WiFi” refers hereinafter to the technology that allows an electronic device to exchange data or connect to the interne wirelessly using radio waves.
The term “GPS” refers hereinafter to a space-based satellite navigation system that provides location and time information in all weather conditions, anywhere on or near the Earth where there is an unobstructed line of sight to four or more GPS satellites.
The term “zigbee” refers hereinafter to a suite of high level communication protocols used to create personal area networks built from small, low-power digital radios.
It is an object of the current invention to assist a first user with detection of location of a second user. This can be applied in various situations. For example, a parent is holding a mobile device, and a child is having a bracelet on his hand, which can emit radio signal. The communication between the two devices is limited to a certain radius. Once the child has left this radius, a disconnection alert may pop-up at the parent device.
At this point, the child cannot be located using his bracelet, since he is out of the detection radius of the mobile device. In this scenario, the parent is unable to know where to search for the child. The current invention, in some embodiments, suggests a possible solution in the form of continuously detecting two parameters: (i) distance; and (ii) relative direction. Using these two parameters, once the child is out of range, it is possible to estimate his general direction.
Therefore, the present invention provides a tool for which, once a notification of the child being out of range is received by the mobile device, an additional notification also appears, directing the parent on the direction the child will probably be at.
This may be in some embodiments performed in both directions. That is, once the child understands that he is being lost, he will receive using his device, a notification on the possible direction in which his parent is at.
It should be noted, that for the public, this device would be energy efficient and low-cost, since in its most basic form, it requires just a device configured to emit a radio signals and a smart-phone with a designated application installed on it.
