Portfolio

This a complete logic control board for a customized variable Frequency Drive (VFD). It incorporates two STM32 family microprocessors with several analog and digital I/Os. All I/O are optically isolated (analog as well).

Logic Control board for a Custom VFD

This is a control PCB of a controller made for a illuminant controller for medical applications.
This worked in a constant power mode. Power can be adjusted on the fly using a potentiometer.
This control board monitored temperature, current, voltage and power to remain operational within safe limits.
ESD certifications of IEC-60601 were also obtained.

Illuminant Controller for a medical device

This is a front end circuit board for a custom Variable Frequency Drive (VFD).
This incorporates a TFT display, tactile switches, a rotary encoder and an RS485 interface for data communication.
This board utilizes an STM32 ARM cortex microcontroller.

Enhancing Depth maps from Microsoft Kinect using multiple Sensors

Asian Conference on Design and Digital Engineering(ACDDE)

During recent years a new type of depth sensors was made available in the market known as Microsoft Kinect Sensor. Its active sensing technology is well suited for applications that may require higher frame rates. However, it can totally fail in situations where the subject absorbs or reflects the infrared pattern casted by the sensor i.e. specular or transparent and near or far away objects. Kinect depth output contains holes in areas where these objects exist. In this paper we formulate a framew
