In this work, we explore the implementation of the energy efficient I/O interface circuits, namely the analog-to-digital converter (ADC), using back-end-of-line (BEOL) Nano-electromechanical (NEM) relays, for ultra-low power VLSI and IoT applications.

Nowadays, integrated circuits (IC) are mostly implemented using CMOS transistor technology. Due to the inherent leakage property of transistors, whenever they are connected to the power supply, even when the circuit is not in operation, the system suffers from leakage current that passes through the switches and gets wasted. In other words, by nature, the transistors can never be totally turned off.

In the IC fabrication process, metal wires and VIAs (the vertical connection between metal layers) are used as interconnections on the chip for connecting millions ...

In the Internet of Things era, electronics with ultralow power consumption are greatly sought after. In order to implement a microprocessor, basic logic gates and computing blocks are required. We propose a run-time reprogrammable micro-resonator-based device that can be used to implement a compact, reprogrammable multi-input logic gate and also the most compact full adder block ever presented.

The proposed proof-of-concept device consists of a laterally actuated doubly-clamped micro-beam, biased with a DC voltage, with three fixed identical electrodes on each side of the beam, in which the logic inputs (DC voltages), applied at the four corner electrodes, electrostatically tune the resonance frequency of the beam. The middle electrodes are used for driving the resonator and sensing its output. ...

New multimedia language
We are still dealing with words, whose communicative system is writing based on the pen, now keyboard, as the main instrument and reflecting a six thousand years old technology, writing. The scope is to communicate a concept, an idea, an order, anything. For that purpose we must develop a new common language, based in a universal common and single software that includes words, spreadsheets for calculations, drawings, pictures, video, audio, animation, schemes, diagrams, icons and other available media to create an all new advanced language of universal utilization.

At the moment we have the technology that can supersede the words and writing as the main means of personal communications. Pictures, video audio, animation, schemes, diagrams, icons ...

Vehicle plate Barcode System (VPBS)

In modern society, speed of information circulation is increasingly critical. Responding to this need, I have designed a project that serves both police and citizens in saving time, security and effort.

This project aims to develop a security system on all vehicles; this system will aid police officers in easily obtaining information stored by the department of motor vehicles (DMV) at the Secretary of State office (SOS). The idea for this system begins with a barcode label for each vehicle. This barcode contains all information related to the registration of the car and the owner. For example, it would include the vehicle title, registration, VIN, and owner’s information (identification, SSN, phone number, and history ...


Mobile video calling is the most convenient communication technology available to common people today. But, this doesn’t come any close to real “Face to Face” communication. In face to face, person can move around & control their visual (eye-ball movement & focus) and audio content (adjusting reception sensitivity & directivity dynamically) which makes it real. But, such sensory controls are not possible and very much spatially limited in today’s smart phone.

The idea here is to get visual (camera) & audio (MIC) sensors flying around & controlled by both parties to make communication more real.


CONTROL SENSOR: The person’s head movement is tracked by inertial (gyro, accelero, magnetometers) sensor and eye movement is tracked by ...

This idea came from the analysis of why symmetric-multi-processing (SMP) architectures failed to perform well when given an intrinsically parallel software task (circuit simulation in Verilog) - despite being able to get as many as 48 CPUs on a chip these days, simulation acceleration usually tops out at about 4x on 8 cores. The two problems with SMP are data-bus congestion and missing cache, and the idea with "wandering threads" (WT) is to alleviate that by enabling more efficient use of CPU caches, and taking traffic off the data bus, by moving threads instead of data.

The main technique used is to ask at routine call boundaries whether a thread should continue operating on its current CPU or transfer ...

The uRADMonitor AIR is a small device with an opto-electric Particulate Matter sensor that tracks your environment wherever you are. It shows the best routes in town for doing jogging, cycling, or taking your kids for a walk. In the background it contributes with valuable data to pollution mapping across wide areas.

The device has a BLE Bluetooth low energy module that connects to your phone. On the screen you see real time air quality indicators and simple health hints, while in the background the phone sends the data online to the central server.
Particulate Matter pollution causes half a million premature deaths in Europe, every year. It's time we solve that, with increased awareness and with real time ...
