Box 1 is protected with a lid 27 that can be made of metal or plastic.

An integrated circuit board 35 incorporating a voltage regulator 38 that lowers the voltage from 12V to 5V is provided in box 1 , Figure 3, in order to power the components operating at 5V (microprocessor, microcontroller, fan) and a microprocessor 39. The microprocessor 39 is intended to be the brain of the device. It has installed an operating system on which a dedicated program is received which receives the signal from the motion sensor/video camera 29 and decides to start an activation by commanding the led lamp 24, the motor 3, it runs the audio file, or the odor sprayer 28, connects to the web platform or the mobile application. The electronic board 35 may further contain a microcontroller 40. The microcontroller 40 receives the command from the microprocessor and in turn controls the motor, the led lamp, the RGB control light indicator 33, the fan 38, the voltage sensor, and receives a signal from the motion sensor which it sends further to the microprocessor. On the electronic board there is also provided a battery clock module 41 which allows time to be counted when the device is turned off, a motor driver 36 which receives the command from the microcontroller 40 and in turn controls the motor motion 3, an audio amplifier 37 which increases the signal strength received from the microprocessor 39, a temperature sensor (not shown) that measures the temperature inside the box 1 and sends it to the microprocessor 39 which decides whether to turn on the fan 38 - usually over 50°C, a voltage sensor (not shown) which is intended to determine, if the device is connected to an external battery, the charging level of the battery and to warn the web platform when it needs to be recharged, an infrared position sensor (not shown) which is intended to detect the position of the mechanism and transmit this information to the microprocessor 39 via microcontroller 40 and an audio loudspeaker 34 which plays the audio files sent by the microprocessor 39 through the audio amplifier and a fan 38 which starts when the temperature inside the device exceeds a certain value (50°C). On the electronic board 35, there are also installed integrated WiFi/Bluetooth modules designed to transmit and receive radio signals over WiFi in order to communicate over the Internet via the dedicated application or to connect the device via Bluetooth to the mobile phone through the dedicated application. As a rule, the Bluetooth module is integrated with the WiFi one, but they are two different technologies that are used differently and can be installed separately. The communication means C further comprises a cellular transmission module 31 , if a WiFi network is not available, allowing it to connect to the Internet and transmit/receive data. There is also a start/stop button 42 on the back of the box.

According to Figure 5, box 1 is placed on the shelf behind the visible line of products.

Outside the box 1 , a motion sensor 29, a led lamp 24 and an odor spray 28 are installed on the back of the box 1 via USB ports. The lamp has a magnet 26 which allows it to be attached to the metal housing 279 of the device or to the metal shelves. A RGB light indicator 33 is installed in front of the box 1 which indicates the operating state of the device by changing the color or frequency of the signal. At the external end of the shaft 10 is installed the universal grip system 32 to which the product 25 to be promoted is attached.

According to another embodiment, the motion sensor 29 is replaced by a video camera.

According to Figure 6 the attachment of the shelf device can be made by rubber or plastic/silicone rubber suction cups 45 or by magnet 44 or by hook-and-loop stripe 43.

The mode of operation is shown in Figure 7. As soon as the motion sensor or video camera 29 detects the presence of the consumer in proximity, a signal is sent to the microprocessor 39. It triggers an activation consisting of moving the product back and forth on the x-y axes in synchronous playback of the audio file (which may be a promotional message or a piece of music), turning on the led lamp 24 and/or the odor spraying by the odor sprayer 28.

Specifically, in order to move the product, the microprocessor 39 transmits a command to the microcontroller 40 which in turn gives a command to the motor driver 36 controlling the movement of the motor 3. The motor 3 moves the shaft via the transmission system T consisting of the pulleys 5, 7, belt 6 and crank rod 8. With dedicated software, one can set more types of movement: slow or fast, random back and forth, constant back and forth, or if the audio file contains a song, a precise control of the movement in the rhythm of the music, so that the product seems to dance. Through the dedicated audio software one can also set the audio volume, as well as the flashing sequence of the led lamp 24 and the odor sprayer 28.

At the same time, by counting the number of activations and the number of motion sensor or video camera triggers 29, a report is generated that is forwarded to the dedicated server.

When the video camera is used for detection, the audio message can be customized according to the consumer profile (Example: The message for a young woman may differ from that for an elderly man).

The settings for each promotion campaign are made on the dedicated web platform and are sent to the device via the Internet.

To set up a new Internet connection, one can use the dedicated mobile application that connects to the device via Bluetooth. It may also be used to transmit the location in which the device is installed, to set the volume and to test the smooth operation of the motion, the led lamp 24, the motion sensor or the video camera 29, the fan 38 and the odor sprayer

28.

The use of a led lamp 24 to illuminate the product 25 can be synchronized with the movement of the product and the sound reproduction. This lamp can be illuminated for the entire duration of the activation, or it can be programmed to flash at preset intervals or to illuminate at the customer’s request.

The smell dispenser 28 is connected via USB and sprays the aroma at preset intervals depending on the traffic in the store. Setting up this system will also be done through the dedicated web platform.

By using a motion sensor or a video camera 29 for detecting the consumers and triggering the activation of the device, depending on the type of detection used, it will be possible to extract traffic data from the respective shelf where the device is installed, as well as the number of interactions with the consumer. If a video camera is used, the audio message can be customized according to the consumer profile (Example: young or elder man, young or elder woman). This information will be uploaded to the web platform and will be sent as a report to the customer.

Information transmission is provided by the means of communication, namely the WiFi/Bluetooth module 30, the cellular transmission module 31 , modules which allow, in conjunction with the web platform or the mobile phone application, to remotely transmit the motor operating parameters 3, the parameters of the led lamp 24, of the smell dispenser 28, to upload new audio files, to set the operating range of the device, to remotely monitor the operation of the device as well as in case of malfunctions, indications about the nature of the malfunction.

It will be understood that various details of the object described herein may be altered without going away from the scope. Furthermore, the foregoing description is merely intended to illustrate and not limit, so that the subject matter of the invention is defined by the claims set forth below.
