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.

Seiden Law LLP issues statement: Prosecuted by Press Conference: Declared Guilty Without a Charge, Yim Leak Family Asks UN Human Rights Experts to Hold Thailand to Its Own Treaty Commitments8.10.2026 19:26:00 EEST | Press release

Seiden Law LLP, chief global counsel to Cambodian businessman Yim Leak, announced today that Jared Genser, international counsel to Mr. Yim and his wife, has asked two UN Special Rapporteurs to send an urgent appeal to the Thai government. The request is made on behalf of the couple and their seven-year-old son. It says Thailand violated its international human rights commitments by announcing the family’s guilt before any court had tried them, and by freezing their assets, including their minor son’s savings, without a hearing. Six Official Statements in Nine Months. No Charge Filed in Any Court. Between December 2025 and September 2026, Thai officials described Mr. Yim as the center of a criminal network on six occasions: at two press conferences chaired by the head of the Thai government, in the House of Representatives, and in three government press releases. The head of the Thai government said the network had been “found to have committed” offenses. Asked about the suspects’ lawy

Sam Altman-Backed Meanwhile Raises $37.5M as Families Across Asia, Europe and the Middle East Turn to Bitcoin Life Insurance8.10.2026 19:12:00 EEST | Press release

Meanwhile, the first life insurer licensed to operate entirely in Bitcoin, today announced $37.5 million in new funding from its existing investors. Bain Capital Crypto led the round, alongside Haun Ventures, Framework Ventures, Pantera Capital, Apollo, Northwestern Mutual Future Ventures, and Morgan Creek Digital. Meanwhile, whose backers also include Sam Altman, has now raised more than $180 million. The round follows a surge in international demand for Meanwhile’s Bitcoin life insurance policies, particularly in Asia, Europe and the Middle East amid broader macro instability. In early 2026, Meanwhile launched BTC Life 1-Pay, a single-premium whole life policy built for high-net-worth clients outside the United States. It is the company's second product line after BTC 10-Pay, which is purposely designed for US taxpayers. As the company eyes further international growth, Meanwhile has signed 15 brokers serving wealthy families since launch, including in the insurance hubs of Singapore
