Kyoto Semiconductor Announces Two UV Sensors for Deep UV Sensing Applications
7.2.2023 04:30:00 EET | Business Wire | Press release
Kyoto Semiconductor Co., Ltd. (President and CEO Yoshihisa Shinya, Head office: Fushimi-ku, Kyoto city), a leading optical device solution manufacturer with world-class technologies and Japanese quality, has announced two products of GaN*1 UV sensor; "KPDU086SU27-H11Q and KPDU086SU31-H11Q".

The UV sensors "KPDU086SU27-H11Q" and "KPDU086SU31-H11Q" were developed with the aim of achieving higher sensitivity than conventional Si*2 type UV sensors to meet the needs of the deep UV*3 sensing market.
Since conventional Si-type UV sensors detect a wide range of wavelengths, it is common to apply a filter to limit the sensitivity to the UV wavelength range. The amount of light was attenuated by passing through the filter.
The newly developed KPDU086SU27-H11Q and KPDU086SU31-H11Q use GaN to enable direct light reception at the light receiving part of the sensor without using a filter as GaN has sensitivity to a specific wavelength range of ultraviolet light. It is now possible to obtain approximately three times as high sensitivity as Si-type UV sensors. *4
In addition, the products have sensitivity in the wavelength range limited to UV-B*5 and UV-C*6, which are in high demand among ultraviolet rays.
The new products can be used to monitor the ultraviolet light intensity of germicidal lamps in food factories, medical institutions, and water purification-related institutions, and to monitor the light intensity of ozone detection light sources.
The mass production of the GaN UV sensors "KPDU086SU27-H11Q and KPDU086SU31-H11Q" are scheduled to start on April 28, 2023.

Megaport Launches Storage, Unifying Its Automated Infrastructure Platform Alongside Compute and Network Offerings4.6.2026 01:47:00 EEST | Press release
Megaport Limited (ASX: MP1) (“Megaport”), a leading global automated infrastructure platform, today announced the launch of Megaport Storage, expanding its platform to deliver integrated compute, network, and storage services. Megaport Storage integrates high-performance, enterprise cloud storage directly into the Megaport Network and Latitude.sh compute platform, giving enterprises a unified foundation that covers the three key pillars of IT infrastructure: compute, network, and storage. The launch marks a culminating step in Megaport’s evolution, delivering predictable costs, seamless scalability, and direct data access wherever customers operate. “With the launch of Megaport Storage, we’re not just connecting your cloud anymore; we’re providing the foundation for it,” said Michael Reid, CEO of Megaport. “By aligning storage needs directly with workload requirements on our global ecosystem, we’re combining the performance of dedicated infrastructure with the scalability and flexibili
C.H. Robinson Launches World's First AI Technology That Continually Assesses, Improves and Operates Global Supply Chains3.6.2026 19:00:00 EEST | Press release
As the global leader in Lean AI supply chains, C.H. Robinson has built the first AI technology designed to both operate a shipper’s global supply chain and also continuously assess and improve its performance. Now serving the company’s 4PL Managed Solutions customers, a new Lean AI Engineer works in concert with the Lean AI Planner introduced last year to create one connected system that uniquely enhances a supply chain as it runs. This press release features multimedia. View the full release here: https://www.businesswire.com/news/home/20260520874794/en/ The Lean AI Engineer can assess an entire supply chain in 25 to 30 minutes and determine improvements before performance is impacted – compared to supply chain assessments that typically take up to four weeks and look backward at what has happened instead of what should happen. While the Lean AI Engineer delivers intel, the Lean AI Planner manages shipments through hundreds of interconnected AI agents and in turn feeds more data back

Stabilizing Grids and Cutting Costs in Half: Europe Is Banking on Grid-Relevant Storage Systems3.6.2026 16:50:00 EEST | Press release
The European battery market is scaling up at record speed: According to the latest Solar+ Report from SolarPower Europe, at the end of 2025, the installed storage fleet in the EU had reached a total capacity of 40 gigawatts (GW) and a storage capacity of 77 gigawatt hours (GWh). This is an increase of over 45 percent compared to the previous year. By 2030, the study’s Solar+ scenario forecasts that capacity will quadruple to 171 GW, while storage capacity will increase eightfold to 598 GWh. As growing solar and wind capacities place increasing demands on European grids, storage systems will need to shift electricity over many hours. As a result, the average storage duration will go up from 1.9 to 3.5 hours. This represents a technological leap that underscores the need to establish more grid-relevant storage systems. Taking place in Munich from June 23–25, ees Europe will showcase how the industry is meeting this enormous demand. As Europe’s largest exhibition for batteries and energy
