The object is to build a web based application. Budget is not constraint now. Takes input in the form of a collection of one or more images The input will also include a structure/arrangement of images. Identify similar structure in a large set of PDFs containing images Display results that match the structure and individual input images The above application will be used to find the presence of small circuits within large circuits. So a user can provide images of two transistors connected in a particular way. The system will then find a similar arrangement in all the other circuit images that it has in its database. Opencv can be used for image processing. Type of application development required: New Application Integration requirements: Standalone Application Purpose or functionality of application: Take set of images as input Take structure as input. Structure defines how these images are arranged w.r.t each other Identify similar structure/arrangement in the set of availab...

We are a start-up (  [obscured]  ) developing and manufacturing integrated micro-electronics circuits (chips) that are used by scientific community to study neurons and in particular neuronal networks and retina. For instance, a network of neurons derived from stem cells can be cultured on our chip up to form a sort of "mini-brain" and then our chip is able to sense the electrical activity of the neurons (which is the language used by neurons to communicate) in order to study neurodegenerative diseases such as Alzheimer's Disease. Our devices represent the interface between the neuro-biological world and the digital-electronic world. The novelty is that our chip integrates thousands of sensors (each sensor can interface with a neuron, hence we can read-out from thousands of them), while past devices had only ~60 sensors. We need an illustration (either 2D or 3D) to express these two main concepts: (i) neuro-chip interface and (ii) high-resolution. The illustration should sh...

I need an electrical engineer to help me design a small ultrabright LED prototype product for my clothing line. I have 3D renders completed and a basic idea of what I want in the electrical platform. Although, I do need the entire interior electrical platform built for this product. I am hoping to get the prototype built and a small product run completed at least 12 working units. This is a pretty simple design and functionality. I am also looking to have this completed in the $1000-$2000 range. I look forward to hearing back from you all.

Hitting the golf ball on the 'sweet spot' of the club gives a player the maximum benefit of a proper swing. We need engineer's to help us build a club that will, on impact with the golf ball, identify on a smart phone or on the club it self, where the club struck the ball (position). Some of possible sensors that could be used are vibration sensors, pressure sensors and then triangulate the point of impact and display that on a smart phone (via BT) or on the shaft of the club with some LED indicators. Any freelancer selected, will be required to sign a NDA and provide references for their past projects.

We need a working prototype of an kitchen appliance. Professional candidate will start with a document describing how the appliance works and design a circuit, prepare a PCB layout and built the prototype. This prototype involves a infrared sensor, thermostat, fan and a hotplate. This product requires two inputs temperature in Fahrenheit or Celsius and distance in inches or millimeters. Based on input values of temperature and volume, output is varied. Output controls the speed of a fan and resistance to the hotplate. More details about the project are available after signing a confidentiality and non-compete agreement. There is room to pay a higher rate or longer hours if justified.
