Sanner UK engineers shine at the office opening party with industry-related demonstrations. <\/strong><\/h3>\n

It was with great pleasure that we welcomed friends, industry partners and clients to our offices for drinks and networking last week to celebrate our new premises.<\/p>\n

To entertain our guests while they admired the new labs and workshops, we challenged our engineers to come up with some cool and interesting games. The team did not disappoint, and our visitors had a few tricky challenges on their hands!<\/p>\n

No compasses allowed<\/h2>\n

In one of the general-purpose labs, users were asked to draw a<\/strong> perfect, 5-cm-diameter<\/strong> circle <\/strong>on a sheet of paper. An imaging rig we\u2019d built in just a few days, with some custom software, then automatically assessed how well each person did (in terms of both size and circularity), read their handwritten name, and compiled a leaderboard. Although this demonstrator was designed just to kindle our guests\u2019 competitive instincts, it is an illustration of how quickly a computer vision setup can be made to analyze devices under test, control quality on a production line, or even monitor hand tremors in patients with Parkinson\u2019s disease.<\/p>\n

Seeing the invisible<\/h2>\n

Another hit was showing the power and fallibility of the infrared camera. Most people were familiar with the use of infrared imaging to measure temperatures. However, many were surprised to see that using this camera, a window acts as a mirror; and conversely silicon, which we normally consider opaque, is quite transparent. Understanding how infrared light interacts with different materials is essential to correct interpretation of its measurements, and can help inform design decisions in everything from heating systems to drug container materials.<\/p>\n

Imperfect pitch<\/h2>\n

How can you analyze the inner workings<\/strong> of a device that you can\u2019t open? This is a common challenge for developers of devices for which the caseworks are tightly integrated into their function, like many autoinjectors. The Sanner engineers showed how audio spectrograms<\/strong> can provide a non-invasive check-up on the performance of a prototype syringe driver. Just for fun, we also asked our visitors to listen to a pure frequency, and challenged them to match it by adjusting the length of a cantilever plucked with a guitar pick. The results highlighted how audio analysis allows a closer, more accurate inspection than our ears alone could determine, and interestingly showed that the great majority of players\u2019 judgments were flat!<\/p>\n
