Abstract: The invention discloses a method to set up a cross-domain DDS-secure network and then use it to transmit various kinds of data. To set up the cross-domain DDS-secure network, we first register IoT and monitor devices on the administration website. Second, we group devices based on our needs and then ask the website to generate configurations and certificates for each device. Finally, we download those files and deploy them to each device. In an extremely case, we can accomplish all operations only through a mobile device. During the system operating, all devices establish the DDS-secure connections to each other, and data will transmit on the network securely.

Abstract: A semiconductor die package includes a high dielectric constant (high-k) dielectric layer over a device region of a first semiconductor die that is bonded with a second semiconductor die in a wafer on wafer (WoW) configuration. A through silicon via (TSV) structure may be formed through the device region. The high-k dielectric layer has an intrinsic negative charge polarity that provides a coupling voltage to modify the electric potential in the device region. In particular, the electron carriers in high-k dielectric layer attracts hole charge carriers in device region, which suppresses trap-assist tunnels that result from surface defects formed during etching of the recess for the TSV structure. Accordingly, the high-k dielectric layer described herein reduces the likelihood of (and/or the magnitude of) current leakage in semiconductor devices that are included in the device region of the first semiconductor die.

Abstract: An optical module for protecting human eyes includes a first support element, first conductive paths, a lens, at least one second conductive path, and a light-emitting element. The first support element has a bottom plate and a sidewall on the bottom plate. The first conductive paths are in the first support element or outside the first support element. Each of the first conductive paths has a first end adjacent to a top surface of the sidewall and a second end adjacent to the bottom plate. The lens is located on the top surface of the sidewall. The second conductive path is electrically connected to the first ends of the first conductive paths. The light-emitting element is located on the bottom plate of the first support element. When a resistance difference is detected through the first and second conductive paths, the light-emitting element is switched off.
