Distance-Based Sensors Measure Up
2/7/2013

Single-Pixel Technology, alternately known as background suppression (BGS), is ideal for ignoring objects in the background and for consistent detection of objects in the near field, regardless of their color or reflectivity.

Jeff,  Thanks for the excellent piece on distance-based sensors.  It's interesting how the technologies have evolved to meet increasingly complex application demands.

One thing I'm curious about is so-called "smart sensors." If a sensor has on-board hardware and software, is it more able to ignore the objects it doesn't need to see?

An interesting article on an emerging technology and something I didn't know much about until now. Thanks for your article and perspective, Jeff.

Great article! We at XYZ Interactive Tech. have developed a distance-based IR sensor that merges the technique of angle measurement and signal strength of a reflected IR pulse. This can be done in a low-cost package to output distance with customized resolution and accuracy. We have extended this principle to design sensors in 2D and 3D to recognize hand gestures for "smart" switching technology applications.

Thank you for that good information. This is certainly simpler than using a neural network or complex edge detection algorithms.

I completely agree. In the past I was doing numerous triangulations to basically do he same. The only difference was the distance. My aplications included lond range lasers for target detection.

Smart sensors is a promising area for innovation in 2013.  The combination of more powerful processors, networking connectivity and mass customization of sensor designs is opening up lots of possibilities  for more intelligent sensor solutions. Add to that wireless technology, especially for factory applications, and we can expect to see an area ready to keep developing new products.

Manufacturers of plastic parts recognize the potential of conformal cooling to reduce molding cycle times. Problem is, conformal molds require additive manufacturing (AM), and technologies in that space are still evolving. Costs also can be high, and beyond that, many manufacturing organizations lack the knowledge and expertise needed to apply and incorporate additive technologies into their operations.
Machine vision and video streaming systems are used for a variety of purposes, and each has applications for which it is best suited. This denotes that there are differences between them, and these differences can be categorized as the type of lenses used, the resolution of imaging elements, and the underlying software used to interpret the data.
In the face of growing challenges for embedded technology engineers, designers should actually be designing for a new IoT -- the Internet of Tomorrow.
As today’s product design cycles are held to tighter schedules and budget constraints, it’s becoming even more critical to consider human factors up front to catch and fix problems during the initial development stages, when it’s faster and less costly to do so. Overlooking human factors at the beginning of the design cycle could lead to poor user experience, a decrease in effective product performance, and an increase in safety risk to the user.
Plastic part manufacturers are always looking for ways to reduce cycle time and get more productivity out of their injection molding machinery. One of the longstanding constraints in injection molding production has been cooling time. Removing parts from the mold before they have cooled induces warping or shrinking. But wait time works against productivity.
