## Background
CROSS REFERENCE TO RELATED APPLICATION
The present application claims the benefit and the priority of the U.S. Provisional Patent application Ser. No. 61/846,983 filed on Jul. 16, 2013 with title, “SMART BABY WALKER WITH A BRAKE SYSTEM TO CONTROL THE BABY'S RANGE OF MOTION”, and the contents of which is incorporated in its entirety as reference herein.
TECHNICAL FIELD
The embodiments herein generally relates to baby walkers. The embodiments herein particularly relates to a baby walker with a safety feature. The embodiments herein more particularly relates to a baby walker with a braking mechanism to avoid an obstacle in the walker's way.
DESCRIPTION OF THE RELATED ART
Baby walker is one of the ordinary facilities to help a toddler to start walking. The problem with a baby walker is a lack of control for the parents on the baby walker along the route the child goes and encounters the dangerous things like the heater and areas such as stairs. The problem of collision of the walker with the obstacle occurs when the parents are not available nearby or around to monitor a baby.
The baby walkers available in the present day market do not have the option of control during an encounter with dangerous areas. Some of the walkers have just a foot brake that stops the baby by the will of the parents. Among the patented inventions, the closest prior art invention is US patent numbered U.S. Pat. No. 6,983,813 entitled “remote controlled and motorized baby walker”. The prior art patent discloses a baby walker with a motor and a remote control. Also the sensors on the walker prevent it from encountering the barriers. But the patent does not have any clear description about the brakes and the sensors electronic function.
Another German Patent numbered DE29814240 discloses a baby walker with a special brake and anti-slip instruments and does not provide any description about the used sensors.
Thus none of the baby walkers is provided with a baby walker to control the movement of the baby walker during the movement walker near dangerous or hazardous things like heaters, ponds, etc and areas like staircases, etc.
Hence there is a need for a baby walker with a braking mechanism to control a movement of the baby walker from walking into dangerous areas. Further there is a need for providing a safety and security system that is fitted to any existing baby walker system to prevent a movement of the baby walker into forbidden areas and to secure the baby walker from unpredicted dangers. Still further there is a need for a safety and security system for a baby walker which intimates the baby's parents on the obstacles that are present on the way of the baby walker.
The above mentioned shortcomings, disadvantages and problems are addressed herein and which will be understood by reading and studying the following specification.

The various embodiments herein provide a baby walker with braking mechanism to control movement of the baby walker from moving into dangerous areas. The baby walker comprises a sensor unit, a wave transmitter system 107, a braking system and a power supply unit 104. FIG. 1 illustrates a perspective view of the baby walker with braking mechanism, according to an embodiment herein. The sensor unit 101 is configured to sense an obstacle in the way of walker. The wave transmitter system 107, in communication with the sensor unit, is configured to generate signals on sensing the obstacle. The braking control system 102, in communication with the wave transmitter, is configured to control movement of the walker upon reception of signals from the wave transmitter. The power supply unit 104 is configured to supply electric power to the sensor unit, the wave transceiver the braking system. FIG. 2 illustrates a front view and a side view of the baby walker with braking mechanism, according to an embodiment herein.
FIG. 3 illustrates a perspective view of the sensor unit of the baby walker with braking mechanism, according to an embodiment herein. The sensor unit further comprises a box with an outer cover 301 provided to house a plurality of flashlights, an infrared radiation transceiver 302 and a LED bulb. The infrared rays are used to detect any obstruction from the obstacle. The LED bulb 303 indicates the on/off status of the infrared sensors. The infrared transceiver 302 is configured to radiate infrared rays in all the directions through flashlight 302. When any obstacle appears in front of the sensor unit, the infrared radiation falling on the obstacle gets reflected. The reflected radiations are collected by the infrared transceiver 302 and are transmitted to the wave transmitter. The infrared source embedded in the flashlight has an adjustable range from 5 to 50 cm. A plurality of sensor units is placed on the baby walker, so as to receive accurate detection of the obstacle. For example, three sensors are placed in front, three sensors are placed in middle and three sensors are used at the end of the walker. The infrared sensors are positioned in the middle of a lower bumper because the front bumper has got a chance of hitting the objects such as wall, chair, etc. When the sensors are placed on the lower bumper, the sensors are not damaged in case the walker hits an object. The sensor units are also placed in certain unsafe places such as stairs, fireplace, kitchen, etc. The sensor unit further comprises various types of sensors, lasers and cameras 106 (as shown in FIG. 1) such as metering sensor, thermal sensors, color sensitive sensors, subsonic sensors and also different types of transmitters like infrared 302, radio 301 and optical transmitters 304 maximize the detection of obstruction to the walker.
The wave transmitter received obstruction reflected infrared radiation from the sensor unit. The wave transmitter comprises a processor 107 (as shown in FIG. 1) which is configured to analyze the reflected radiations and estimate position of the obstacle and the walker. Depending on estimation of distance between the walker and the obstacle, the wave transmitter transmits an intimation signal to the braking system, when the walker gets too close to the obstruction. The wave transmitter further transmits a different signal to braking system when the walker is moved away from the obstruction. The wave transmitter as well activates an alarm 105 (as shown in FIG. 1) as soon as the brakes are applied to the walker. The alarm goes off only when the walker is moved away from the obstacle.
FIG. 4 illustrates a perspective view of a braking system, a top view of the braking system and a front view of the braking system in a cover removed condition of the baby walker, according to an embodiment herein. FIG. 5 illustrates an exploded assembly view of the braking system of the baby walker, according to an embodiment herein. The braking system of the baby walker comprises a main body 401, a brake blade pad 402, a servomotor 403, a brake blade guiding rails 404, a rotating disk 405 and a connecting rod 406. The servomotor 403 is positioned over the main body 401 which contains the brake blade pad 402, the guiding rails 404, connecting rod 406 and the rotating disk 405 inside it. The brake blade pad 402 is connected to the disc 405 through a connecting rod 406. The brake blade 402 is designed to move along the pair of guide rails 404 fixed to the side walls of the main body 401 and the guide rails 404 are provided inside the main body 401. As the intimation/notification/detection signal is received from the wave transmitter, the servomotor 403 is activated to rotate the rotating disk, which in turn drops down the brake blades through the guiding rails to contact with the floor surface and stop the walker. Silicon plastic is used at the end part of brake blades 402 so that the blades have proper grip to the carpet, tile, etc. The end part of the blade that hits the surface is covered with silicon or compact plastic for better friction and adherence of the two surfaces. When the walker goes further away from the infrared light, the brake blades 402 go up and the walker continues moving. The guiding rails 404 move when the brake blade goes up and down.
The brake system is equipped with remote control and is designed in a way that it is possible to be removed as parents/guardian wish. Further a Bluetooth system is set on the walker which enables the parents/guardian to check the position of the baby and lock or activate the brakes. Further the parents/guardian is able to start or stop the alarm via cell phone, laptop or computer. For this purpose a program is installed on the laptop or cell phone and also the processor of the wave transmitter. The processor is further configured to transmit signals via Bluetooth to the walker in-order to perform various activities such as stop or start order of the brakes, and the alarm order.
The power supply unit of the walker is configured to supply power to the sensor unit, the wave transmitter and the braking system of the walker. A plurality of LED bulbs is placed on the walker to indicate on/off status of the sensors, braking system and battery indicator. The power supply unit comprises a battery as a source of power supply. The power supply unit is adaptable to various kinds of rechargeable AC or DC batteries such as a rechargeable lithium battery. The power supply unit further comprises a charging port which is adopted to charge the battery of the walker. The power supply unit further comprises a plurality of LEDs to indicate the charging level of the battery. For example, three different colored LEDs are used to indicate charging level, where a blue LED indicates full charge; an orange LED indicates medium charge and red LED notifies low battery. By adding to a plurality of the batteries, the various components powered by the batteries work for long-term, hence efficiency of the system is increased.
The various embodiments herein provide a method providing braking mechanism to a baby walker. FIG. 6 illustrates a flowchart explaining the steps involved in a method for providing braking mechanism to a baby walker, according to an embodiment herein. The method comprises the following steps: The infrared radiations generated by the IR transceiver are radiated in all directions through flashlight (601).
