ST Reports Strong FlightSense Sales

ST Micro reports Q2 2017 results. Regarding the imaging business, the company says "As anticipated, Imaging revenues in the second quarter decreased slightly on a sequential basis to $68 million, while we prepare for the ramp of new programs.

On a year-over-year basis, Imaging revenues increased 60% in the second quarter, and for the first half 2017 rose 83% to $140 million driven by ST’s innovative Time-of-Flight technology.

In the second quarter we continued to gain design-wins while delivering high volumes of our “FlightSense” Time-of-Flight proximity and ranging sensors to multiple smartphone OEMs. We now have reached cumulative shipments of over 300 million Time-of-Flight sensors and are in more than 80 smartphone models from 15 different OEMs.

In our Imaging business, we anticipate strong sequential growth, as the key new program ramps in Q3, followed by further revenue acceleration in the fourth quarter of this year.
"

EETimes speculates that the "key new program ramps in Q3" might mean ToF sensor in Apple iPhone 8.

SeekingAlpha publishes the earnings call transcript with one of the questions in Q&A session clarifying the FightSense business:

Janardan Menon - Liberum Capital Ltd.

And just a brief follow-up on the Time-of-Flight, which is in your other division. After a big jump in the second half of last year, that revenue has sort of flattened out. But you are continuously reporting higher number of models and OEM on that particular product. And now I understand that from the second half, that revenue will increase sharply because of the 3D of the special program.

But just on the Time-of-Flight itself, can you give some reason why that revenue is not really rising as a number of model. Is that price pressure coming there? Or what are the dynamics which is happening there?


Carlo Bozotti - STMicro CEO:


I think on the Time-of-Flight, we have enormous number of customers in our end. Of course, we are also working on new technologies for the Time-of-Flight. So, there would be a new wave, but we are pretty happy that the growth is impressive in Imaging and we are investing a lot for the new initiative. This is visible of course in terms of expenses in the P&L, but we have now sort (47:46) the $300 million business of Time-of-Flight that we want to keep going and we have the opportunity. I think it's pretty good and it's a pretty good business. I would say it's very good business, but in parallel, we are investing on new things and this will make – will allow us to make another important step.

Princeton IR Tech Announces 1.2MP 95fps ITAR-free SWIR Sensor

IMVEurope, Photonics: Prinston Infrared Technologies announces its first InGaAs SWIR camera to fall under the no ITAR restrictions. The 1280SciCam, features a 1,280 x 1,024-pixel image sensor on a 12µm pitch, having long exposure times, low read noise, 14-bit digital output, and full frame rates up to 95Hz. The camera is designed for advanced scientific and astronomy applications, and is now classified by the Export Administration Regulations as EAR 6A003.b.4.a for export.

The US government’s export control has been going through a process of reform, which began in 2009 as part of the Obama Administration's Export Control Reform (ECR) initiative. The technology from Princeton Infrared no longer falls under ITAR control, which is equipment specially designed or modified for military use, but now falls under EAR. This, in theory, makes it easier to export the technology outside the USA.

Bob Struthers, sales director at Princeton Infrared Technologies, says: ‘Our 1280SciCam has already generated sales and applications with leading research entities overseas. An EAR export classification will propel our ability to serve these customers promptly and efficiently. This will be very valuable to their upcoming projects and equally beneficial to the growth of our young company.


IMVEurope: A year ago, Xenics SWIR cameras have been granted Commodity Jurisdiction (CJ) approval. This new CJ means that all SWIR cameras supplied by Xenics are now ITAR-free in the US.

Pyxalis and Framos Extend Cooperation

Presseagentur: Framos and Pyxalis extend their custom sensor design cooperation. The companies have been cooperating for several years and now have entered into a formal agreement. This partnership provides Framos partners with fully customized, high performance sensors, including sensor specification elaboration support, sensor architecture, design, prototyping, validation, industrialization and manufacturing.

We’re delighted to work with FRAMOS Technologies in Europe and North America. As a 7-year-old company supplying custom image sensors, we’ve built successful partnerships with customers in many applications from niche markets (aerospace, scientific, defense) to medium volume (industrial, medical) and consumer markets (biometrics, automotive). Thanks to this cooperation with FRAMOS, it is now time to reach a larger market and to provide our capabilities and technologies to a greater number of customers.” says Philippe Rommeveaux, PYXALIS’s President and CEO.
