MUMBAI, India, June 26 -- Intellectual Property India has published a patent application (202641052170 A) filed by The Principal, Mepco Schlenk Engineering College on April 24, 2026, for Low Cost Speech Integrated Refreshable Braille Display Using Solenoid Actuators.
Inventors include Dr. V. S. Benitha; K. Abinaya; R. Pavithra; and J. D. Bhadmesh.
The application for the patent was published on June 19, 2026, under issue no. 25/2026.
Abstract: The low-cost refreshable Braille reader system is comprised of a top layer (110), middle layer (120), and bottom layer (130). The uppermost layer (110) consists of Braille dot output pins (119) and a number of user interface control buttons. The middle layer (120) contains a group of six electromagnetic solenoid actuators (121), (122), (123), (124), (125), (126) in a typical Braille cell design. The last layer (130) includes a microcontroller (131), driver circuits (133), (134), a printed circuit board (132), and a power supply unit (135). The microcontroller (131) will be programmed to accept encoded Braille signals provided by a software module and produces control signals. Tactile output is generated by mechanically connecting the solenoid actuators (121-126) to the Braille dot output pins (119) with linkage mechanisms (127). This system works on a single-cell sequential display system, in which a single Braille character is produced by selectively actuating the solenoids. The system also has a graphical user interface to input text, visualize the Braille and to have operational control, a speech synthesis module that produces audio output that matches the Braille content that is displayed.26005, V
