[0036] FIG. 1B where disclosed device 102 is shown. Device 102 is an electronic baton complimenting conventional baton with electronic features making it advantageous compared to many other batons/torches. The electronic baton bearer is used to perform a journey along with device 102 from one country to another in many sports events. Device 102 includes a plurality of programmable multicolour LED arrays 104, a GPS receiver 108, a plurality of sensors 110 and 112, and a control unit 106.
[0037] In an embodiment, the plurality of programmable multicolour LED arrays 104 is configured for showcasing a plurality of images. The plurality of images is national flags symbolically for all countries with dynamic change in appearance in all locations, wherever device 102 is taken. Each LED arrays 104 disposed along the longitudinal axis of device 102, includes a plurality of energy-efficient programmable LEDs to display national flags of different countries in their colours and designs. During the journey, the dynamic appearance change according to the country and the location bringing warm feelings to the electronic baton bearer and the spectators.
[0038] In an embodiment, the distribution of LEDs on device 102 is uneven with more volume towards the top and very narrow volume near the bottom side. Approximately sixteen LED arrays 104 with narrowing widths have been provided in the structure to display symbolical national flag according to the country by location. To illuminate LEDs a customised PCB has been configured with control unit 106.
[0039] In an embodiment, the GPS receiver 108 is an embedded miniature receiver configured to find locations of the operation of device 102 and helps to identify the country. The plurality of sensors includes an image sensor 112 which is a digital camera to capture images from the front within its field of view (FoV); another sensor is an audio sensor 110 and configured to record audio messages. The messages can be tagged with time and country by location.
[0040] In an embodiment, control unit 106 includes one or more interfaces 114, one or more processors operatively coupled with memory-storing instructions executable by at least one processor. There are around eight functional modules configured with as many printed circuit boards (PCBs) to perform all functions of the device.
[0041] In an embodiment, the electric power to device 102 is obtained from an in-built battery 118, and the power is managed to do efficient usage of battery 118 for a longer duration of operation of device 102 through a power management module. Battery 118 is a Lithium ion battery pack capable to perform longer duration of operation of device 102. The battery 118 can be recharged when discharged using the commercial supply. For switching ON or OFF power supply to device 102, an ON/OFF switch 116 is configured with device 102.
[0042] In an embodiment, material of construction of device 102 is selected at least one or a combination of steel, aluminium, plastic, fibre, or acrylic material. The shape is also selected from at least one geometrical shape including circular, oval, rectangular, or mixed, with a convenient design at the lower end for a firm grip of the bearer. Further, inside device 102, a metal object is placed that acts as a heat sink to absorb and dissipate heat generated while glowing LED arrays 104.
[0043] FIG. 2 shows an exemplary block diagram 200 of device 102 architecture. Device 102 architecture includes LED arrays 104 in communication with LED driver 202. The LED driver 202 is capable of driving the LED arrays 104 with programmable LEDs and storing/retrieving the particular flag pattern. This is achieved through multiple pulse width modulation (PWM) channels, inbuilt flash, one or more serial/I2C interfaces for programmability, and inbuilt timers for generating precise timing signals included in the LED driver 202. To meet this requirement an on-chip microcontroller board 204 is used.
[0044] In an embodiment, the dynamic appearance of device 102 is achieved by displaying symbolic flag colour patterns of the country where device 102 is present at that movement. Such multiple displays require programmability, multi-colour capability, low power consumption, wide viewing angle, required brilliance, and compact size. The surface-mounted LEDs 104 are distributed throughout the structure marked in device 102 with a complex partitioning of emission of light.
[0045] In an embodiment, power management PCB 208, signal processing PCB 206, and a GPS 108 PCB are stacked one below the other along with other PCBs, towards the top of device 102 where more volume is available. The Bluetooth module 210 needs to be very close to the PCB stacked. The stacking reduced the requirement for multiple wires. The microphone 110 being user interactive is placed in a separate PCB near device 102. The camera sensor 112 is placed at the front with a separate PCB, the processor PCB 206 is kept at the back due to the space constraint, and a flexible cable running from the camera PCB to the processor PCB. The power management PCB is fed with the power from battery 118.
[0046] FIG. 3 illustrates an exemplary flow chart 300 for changing the dynamic appearance of device 102. The functions for device 102 start step-wise and step 302 state to switch ON device 102 switch on the master controller 120. This initiates the sync command 304 to sync device 102. If synchronization is done 306, the master controller 120 sets the mode 310. The modes are a geo-location message mode 314, an audio message mode 320, and a master controller mode 326. If the sync is not done or at least one mode is not set, device 102 restores the stored flag 308 of the country that was visited last to display the symbolic flag pattern 332.
[0047] In an embodiment, the geo-location message mode 314, the GPS receiver 108 read the location 316 and maps to lookup from location to show symbolic flag pattern 318. The memory is already programmed for all countries where device 102 is to be carried. Accordingly, the symbolic flag pattern of the vising country is displayed 332.
[0048] In an embodiment, the audio message mode 320 receives and decodes audio input using audio-to-text engine 322. This is carried through digital signal processing (DSP) through an algorithm that detects a primary audio source and isolates it from noise and through AD converter, digital data is obtained. Further, map to lookup table from text to symbolic flag pattern 324. Accordingly, the symbolic flag pattern is displayed 332.
[0049] In an embodiment, the master controller mode 326, the command is received and decoded for the signals 328 to map to the lookup table from country code to symbolic flag pattern 330, and accordingly, the symbolic flag pattern is displayed 332. The master controller runs an application to control and collect data from device 102.
[0050] FIG. 4 illustrates an exemplary block diagram 400 for a method flow of device 102. Method 400 for displaying symbolic national flag of a visiting country includes steps 402, receiving geographic location with the help of GPS receiver 108 to identify a place, and as per step 404 receiving audio through a sensor 110 to record, decode, and map to lookup table from text to an image.
[0051] In an embodiment, step 406 defines receiving images captured through image sensor 112 to transfer them to the master controller 120 with one or more digital tags as required. As per step 408 further displaying symbolic images pattern as per the identified location to display through the programmable multicolour LED array 104 and transmitting data to the master controller 120 for further transmission to a web server 140 of the organising body as per step 410.
