SENSORS: Providing medical electronics design engineers with a reflective device capable of an enhanced sensing range in space-constrained applications, TT electronics OPTEK Technology’s OPB733TR reflective object sensor is being deployed in a wide range of medical equipment. The reflective sensor measures just 0.300 x 0.160 inch with a PC board-mounted profile of just 0.114 inch and incorporates a lensed IR LED and phototransistor elements to collimate the light beam for enhanced resolution at a detection range from 0.4 inch (10mm) to 1.0 inch (25.4mm).
The OPB733TR sensor consists of an IR LED with typical peak emission wavelength of 890 nm, mounted alongside a NPN silicon phototransistor, which responds to light reflected by the object being sensed. The phototransistor output on-state collector current is 0.1 mA (100 mm) at ½ inch (12.7 mm) distance from the target and a 20 mA forward current and VCE of 5V. Rise and fall time for the phototransistor signal is typically 15 mS. The surface mount package is reflow solder compatible to 260C. The sensors are available in 16 mm tape on 7 inch diameter reels, 500 pieces per reel.
Typical pricing for the OPB733TR reflective object sensor is $1.32 each in quantities of 1k. Lead time, if stock is not available, is from six to eight weeks.

Robots that walk have come a long way from simple barebones walking machines or pairs of legs without an upper body and head. Much of the research these days focuses on making more humanoid robots. But they are not all created equal.
The IEEE Computer Society has named the top 10 trends for 2014. You can expect the convergence of cloud computing and mobile devices, advances in health care data and devices, as well as privacy issues in social media to make the headlines. And 3D printing came out of nowhere to make a big splash.
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This discussion will examine what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
