Kyoto Semiconductor Announces Two UV Sensors for Deep UV Sensing Applications
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.

New Study from UK’s Largest Virtual ADHD Service Validates Role of Objective Testing in Delivering Personalized, High-Quality Remote ADHD Care10.5.2025 13:45:00 EEST | Press release
As demand for virtual ADHD care increases, findings from a new study conducted with ADHD 360, the UK’s largest evidence-based digital service specializing in ADHD diagnosis and treatment, reveal how objective ADHD diagnostic and monitoring technology improves patient outcomes and clinical certainty. Presented at the 2025 ADHD World Congress in Prague, Czech Republic, the findings highlight the role of QbCheck, Qbtech’s remote testing solution, in enabling clinicians to make more confident, data-informed decisions, supporting a more personalized and collaborative care model. The tool allows for greater clarity when assessing symptoms and adjusting treatment plans over time, ensuring diagnostic accuracy and helping to improve alignment between clinicians and patients throughout the care journey. The results from ADHD 360’s implementation of this model showcase how a standardized approach to virtual ADHD care improves clinician confidence, reduces wait times, and enhances patient engageme
Ant International Partners with Barclays on Global Treasury Management with Proprietary AI-Powered FX Model9.5.2025 16:57:00 EEST | Press release
Ant International has entered a partnership with leading UK bank Barclays to enhance efficiency and resilience in global treasury management for businesses. Under the partnership, the two sides will combine innovative solutions, including Ant’s proprietary Time-Series Transformer (TST) AI FX Model, to help businesses reduce FX-related costs and risks against global volatilities. At the initial stage of the collaboration, Ant International has successfully completed the first batch of its intra-group FX transactions with Barclays. Ant International’s TST Model is a transformer architecture-based big data model with close to 2 billion parameters. By integrating the latest time series forecasting algorithms, the TST Model predicts patterns over time. Ant also created new pre-training and Supervised Fine-Tuning (SFT) frameworks to train the model and improve its predictions over time. The TST Model now forecasts the company's cashflow and FX exposure on an hourly, daily and weekly basis, w
