Wide-angle thermal MEMS sensor contactless offers Omron’s widest field of view

Wed, Sep 04, 2019

Omron Electronic Components Business Europe has added a wide angle 32 x 32 element version of its D6T MEMS thermal sensor. It offers the widest field of view that Omron has ever delivered, says the company.

The Omron D6T-32L-01A can view across 90.0 x 90.0 degrees, enabling it to encompass a wide area, such as a whole room, from a single point. The sensor offers contactless measurement of temperatures of 0 to 200 degrees C in ambient temperatures of -10 to + 70 degrees C.

Omron D6T MEMS thermal sensors are based on an IR sensor which measures the surface temperature of objects without touching them using a thermopile element that absorbs radiated energy from the target object. They incorporate a MEMS thermopile, custom designed sensor ASIC and signal processing microprocessor and algorithm in a tiny package. According to Omron, the D6T offers the highest signal-to-noise ratio (SNR) in the industry. It converts the sensor signal to a digital temperature output giving a straightforward interface to a microcontroller. The design of the D6T, which measures only 14 x 8 x 8.93mm for the largest 32 x 32 element version, makes it well-suited to temperature detection in a range of IoT and other embedded applications.

The D6T-32L is one of three D6T variants by Omron, joining the 1×8 D6T-8L-09H and the 4×4 D6T-44L-06H, offering 54.5 x 5.5 and 44.2 by 45.7 degrees respectively. These two devices offer contactless temperature measurement between 5.0 to 200 degrees C at ambient temperatures of 5.0 to 45 degrees C.

The D6T sensors can be used to detect abnormal temperatures in industrial equipment on the production line to monitoring of food and other temperatures in the kitchen. This can save costs, allowing preventative maintenance to be undertaken in a timely manner, points out Omron, and can even save lives. They can also detect the presence and location of people in a space accurately and reliably.

Rohde & Schwarz validates 5G NR protocol conformance tests

Tue, Sep 03, 2019

Rohde & Schwarz has carried out 5G NR protocol conformance testing with the R&S CMX500 radio communication tester. The Global Certification Forum GCF has accepted these 41 test cases, defined by 3GPP, in different FR1 and LTE band combinations. Accredited test houses, cell phone and chipset manufacturers can add the CMX500 to existing LTE test set ups, to smoothly upgrade path from LTE to 5G NR testing.

Mobile network operators worldwide rely on the certification schemes of the GCF and PTCRB certification forum for mobile devices in their networks. The CMX500 adds 5G NR signalling and RF testing by measuring the RF parameters of 5G NR transmissions and performing protocol tests. As most network operators will implement 5G NR as an extension of an LTE mobile network, the CMX500 can be seamlessly integrated into existing LTE test environments. It is also ideal for 5G NR testing in standalone (SA) mode. Developers using the R&S CMW500 wideband radio communication tester or R&S CMWflexx test system can continue to use them for LTE measurements and add the CMX500 as an extension to perform tests on 5G NR signals.

The Rohde & Schwarz technology group develops, produces and markets communications, information and security products for professional users. The group’s test and measurement, broadcast and media, aerospace, defence, security, networks and cybersecurity business fields address many different industry and government-sector market segments.

The company has its headquarters in Munich, Germany. It subsidiaries in more than 70 countries, with regional hubs in Asia and America.

“World’s largest chip” has more compute cores for data access

Thu, Aug 22, 2019

Claimed to be the largest chip in the world, the Cerebras wafer scale engine (WSE) measures 216 x 216mm (8.5 x 8.5 inch). At 46,225mm² the chip is 56x larger than the biggest graphics processing unit (GPU) ever made, claims Cerebras.

It has 400,000 cores and 18Gbyte on-chip SRAM. The large silicon area, more than the largest graphics processing unit, enables the WSE to provide more compute cores, tightly coupled memory for efficient data access, and an extensive high bandwidth communication fabric for groups of cores to work together, claims Cerebras.

The WSE contains 400,000 sparse linear algebra (SLA) cores. Each core is flexible, programmable, and optimised for the computations that underpin most neural networks. Programmability ensures the cores can run all algorithms for constantly changing machine learning operations.

The cores on the WSE are connected via the Swarm communication fabric in a 2D mesh with 100 petabytes (Pbytes) per second of bandwidth. The Swarm on-chip communication fabric delivers breakthrough bandwidth and low latency at a fraction of the power draw of traditional techniques used to cluster GPUs, says Cerebras. It is fully configurable. Software configures all the cores on the WSE to support the precise communication required for training the user-specified model. For each neural network, Swarm provides an optimised communication path.

The 18Gbyte of on-chip memory is accessible within a single clock cycle, and provides 9 Pbytes per second memory bandwidth. This is 3,000 times more capacity and 10,000 times greater bandwidth than the leading competitor, claims Cerebras. The WSE provides moree cores, more local memory and enables fast, flexible computation, at lower latency and with less energy than other GPUs, concludes Cerebras.

Porsche invests in Israeli startup TriEye to increase road visibility and safety

Wed, Aug 21, 2019

Israeli startup TriEye, whose Short-Wave-Infra-Red (SWIR) sensing technology enables vision in adverse weather and night-time conditions, has expanded its Series A round to $19 million with an investment from the German sports car manufacturer Porsche. The additional funding will be used for ongoing product development and operations, as well as team growth.

In May 2019, TriEye announced a Series A funding round, led by Intel Capital. Other investors in the round include Marius Nacht and TriEye’s existing investor Grove Ventures. Since its inception, TriEye has raised $22 million, including a seed investment of $3 million led by Grove Ventures in November 2017.

Porsche Ventures seeks strategic investments in business models relating to customer experience, mobility and digital lifestyle, as well as in future technologies such as artificial intelligence, blockchain and virtual and augmented reality. Through its venture capital activities, the sports car manufacturer Porsche invests in new companies that are in the early and growth phases.

TriEye was founded in 2017 by Avi Bakal (CEO), Omer Kapach (VP R&D) and Prof. Uriel Levy (CTO), after nearly a decade of advanced nanophotonics research by Prof. Levy at the Hebrew University in Jerusalem. The company has succeeded in developing an HD SWIR camera that is a smaller size, higher resolution, and a fraction of the price of current technologies. TriEye already succeeded in proving that the technology works and can be mass-produced.

The company’s CMOS-based Raven camera, whose initial samples are due to launch in 2020, is designed to save lives on the roads. Once integrated, the camera will allow ADAS and AV to achieve unprecedented vision capabilities under common adverse weather and low-light conditions such as fog, dust or night-time.

As ADAS systems are expected to operate under a wider range of scenarios, car manufacturers and their suppliers (OEMs and Tier 1s) are realizing that SWIR plays a key role in ADAS and AV sensor fusion in order to achieve full visibility under any weather or lighting conditions. Driving tests and research have shown that even when fusing other sensing solutions such as radar, lidar, and standard cameras, the fusion solution fails in solving the low visibility challenge.

“TriEye is a promising technology company led by an exceptionally strong team with experience in the areas of nanophotonics, deep learning, and the development of semiconductor components,” says Michael Steiner, Member of the Executive Board for Research and Development at Porsche. “We see great potential in this sensor technology that paves the way for the next generation of driver assistance systems and autonomous driving functions. SWIR can be a key element: it offers enhanced safety at a competitive price.”

Avi Bakal, CEO and Co-founder of TriEye, commented: “Our mission is to save lives and reduce risks of accidents in all weather and lighting conditions. The expansion of our Series A round and the addition of Porsche as a strategic investor further proves that SWIR is a critical component in the necessary sensor fusion solution to enable safer and better ADAS and AV.”

TriEye is expected to exhibit at the IAA Conference in Frankfurt from September 11^th-13^th, as well as the AutoSens conference, due to take place on September 17^th-19^th in Brussels.
