Vision Show: Lights, Cameras, Automation

　　The Vision Show took place this week. It was, you might say, rather "visual" with all those colorful LEDs and lasers, plus lots of motion and cameras to catch it all.　　The exhibit hall at the Hynes Convention Center was roughly divided into components — lighting, embedded computers, cameras, and frame grabbers — and systems for visual inspection and automation. There's nothing dull here, what with all the colorful lights and motion. Here's some of what we saw.　　Advanced Illumination, a company with a long history of LED lighting, had enough LEDs to light up the entire hall. As bright as they looked, the lights were turned down quite low to keep from blinding those who passed by.　　The lights were bright at The Vision Show 2018. Photo by Martin Rowe.　　Technical Sales and Product Specialist Daryl Martin explained how the LEDs are configured and driven. In most cases, the LED arrays consist of parallel-serial circuits driven by current sources. Typically, each serial string consists of six LEDs. Then the strings are connected in parallel, all powered by a current source. But each string will develop a unique forward voltage. "How do you compensate for those differences?" I asked. Martin wouldn't say exactly how that's done other than to say that the best way is to have a separate current source for each six-LED serial string. A circuit such as the one in LED strings driven by current source/mirror shows a simple circuit that compensates for those differences in forward voltage.　　U.K.-based Gardasoft Vison manufactures controllers that drive LEDs with current. The company demonstrated a vision system in which some cereal boxes were illuminated by LEDs driven by the company's controllers.　　In addition to LEDs for lighting, The Vision Show also had exhibits of lasers in assorted colors such as these from New Hampshire-based Laser Components.　　Lasers from Laser Components.

This 5-second video shows LED backlighting from TPL Vision that looked even brighter in person, but it's plenty bright here.　　Industrial cameras are the front end of any machine vision system. Connected to desktop, laptop, or embedded computers, cameras capture video where software is then used to look for specific characteristics in an image such as barcodes. But systems can identify almost anything. You can see that in action on some system videos on the next page. Here's a sampling of some of the equipment on display in Boston.　　ixCameras manufactures high-speed, high-resolution cameras. Camera control can be from a PC or tablet. The company's latest 7-Series cameras have CCD sensors capable of 2,048 x 1,536-pixel images.　　An iSPEED 7-Series camera from ixCameras of Woburn, Massachusetts.

In the photo below, the camera is attached to a telephoto lens, but the company also exhibited a fish-eye lens.　　Cameras from Back Bone attach to lenses and provide a link to a PC. Photo by Martin Rowe.　　Neosys Technology was one of several Taiwanese companies exhibiting embedded computers. Machine-vision systems often use these industrial computers for image processing and mechanical control.　　Lucid Vision Labs of Richmond, BC, used flowers to show off its latest Phoenix series of GigE cameras. The image below shows the system and flowers above a photo of a monitor screen containing an image of the flowers.　　Camera maker Imaging Development Systems (IDS) uses a mechanical "bug" in a tube to demonstrate its cameras and software. In the 1-min. video below, you can follow it through the tube and see it on a monitor screen. IDS cameras use GigE and USB interfaces to transfer video.

Siemens Acquires Solido Design Automation

　　Siemens announced it agreed to buy Solido Design Automation, a Canadian provider of variation-aware design and characterization software to the semiconductor industry. Financial terms of the deal were not disclosed.　　The deal is the first acquisition in the EDA arena for Munich-based Siemens since it bought Mentor Graphics for $4.5 billion earlier this year. Solido will become part of Mentor's IC verification solutions division.　　"We see a great opportunity to expand the reach of Solido's technology across our customer base," said  Ravi Subramanian, vice president and general manager of Mentor’s IC verification solutions division, in an interview with EE Times. In addition to continuing to support Solido's existing customers and bring Solido's machine learning-based design and characterization software to existing Mentor customers across its product lines, Mentor intends to package tools from both firms to target new customers, Subramanian said.　　Solido is a venture-capital backed firm founded in 2005 in the Canadian province of Saskatchewan. Solido's Variation Designer IC design tool is used for variation-aware design of memory, analog/RF, and standard cells, while its characterization sweet offers fast and accurate library characterization tools that incorporate machine learning technology.　　According to Amit Gupta, Solido's founder, president and CEO, Solido has been growing rapidly and has been featured for two consecutive years on Deloitte's Technology Fast 500 list of the fastest growing tech firms.　　"Becoming part of Mentor now is a tremendous opportunity for us to get broader adoption for our technolgy," Gupta told EE Times. "We are excited about getting the reach of Mentor's channel to get our products more broadly adopted in the market."　　The deal provides a glimpse of what may be more aggressive movement on the merger and acquisition front under the Siemens umbrella. Mentor has traditionally been less active in M&A than its main rivals, Synopsys and Cadence Design. Subramanian said Siemens' ownership gives it both the commitment to EDA and the deeper pockets to "selectively pursue" acquisitions that make sense for growing Mentor's business.　　"Siemens offers greater resources and the ability to pursue the right acquisitions with the right ROI," Subramanian said.　　Solido and its roughly 65 employees, including Gupta, will be folded into Mentor. The company believes its location in Saskatchewan gives it access to a broad pool of talent. Mentor expects the deal to close early next month.
