Patent ID: 10380915

Abstract:
The Braille Dot Delivery System is an enhancement design from the Publication No.: US-2012-0295232-A1, which implements the same concept for delivering Braille Dot characters via electronic pulses; the system comprises of the Low Frequency Pulse Output Device Pad [140] and the Computer/Signal Transmitter [200], where the wireless receiving unit receives information from the Computer/Signal Transmitter [200] generates electrical pulse(s) to replicate a Braille dot-like character. The Low Frequency Pulse Output Device Pad [140] contain electrodes in a 3×2 matrix cell; each cell consists of a set of electrodes, one for positive signal and another negative signal or ground; completing the circuit is the electrode gel pad, a medium between the electrode cell insert and human skin surface contact, there delivers an electronic pulse at low applied current. The Computer/Signal Transmitter [200] allows for creating Braille Dot characters by the key buttons and functions as a central processing unit to communicate, transmit, and receives information with other devices like smart phone, tablet, laptop, desktop, World Wide Web, and other communication devices.
