Smart Glasses for Blind People

Smart Glasses for Blind People

The glasses incorporate a camera that captures the surroundings and processes the images using computer vision technology. The processed information is then conveyed to the user through audio feedback, allowing them to navigate their environment more effectively. We had to incorporate a Raspberry Pi Zero into the design to handle the processing of the images captured by the camera. The glasses are designed to be lightweight and comfortable, ensuring that they can be worn for extended periods without causing discomfort. This product received funding and is currently being sold: https://sparkvision.tech/bg/smartglasses/

MIL-STD-1553B Bus Interface

MIL-STD-1553B Bus Interface

MIL-STD-1553B Bus Interface was developed to communicate between CDU and multiple RCUs. CDU was acting as Bus Controller (BC) and RCUs as Remote Terminals (RTs).

Pedestrian Crossing Button

Pedestrian Crossing Button

This device is used to Request To Walk while road crossing on the Intersections. This Button communicate with the Traffic Controller over BLE. All the Button on the intersection communicate over Sub-1 GHz and form a network.

Remote Control Unit

Remote Control Unit

RCU is used to control and configure parameters of different Radio Units (Frequency, volume and mode, etc.). Different RCUs were designed for different radios. All the RCUs transmit Radio parameter settings to CDU as well as take parameter settings from CDU and configure the Radios.

Smart Lock

Smart Lock

The Smart Lock is a device for the Bicycle Parking Allocation System in public spaces. Users can reserve parking slots through a Mobile App or Web Interface. Upon arrival, they can lock or unlock their slot using Bluetooth or NFC, ensuring a secure and efficient parking experience.

System Bus Gateway

System Bus Gateway

The Gateway connects to the System Bus and is specially designed for natural gas measurement applications. Applications are the conversion of protocols (e.g. from Modbus to DSfG), bus access to a system bus as a local revision interface or comprehensive (DSfG) data transmission for Ethernet (LAN), GPRS or modem connection.
