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 device includes a gate structure on a substrate; a protection layer on the gate structure; a source/drain region adjacent to the gate structure; and an interconnect plug on the source/drain region. The gate structure includes a gate electrode including a top surface; and a sidewall spacer interfacing a sidewall of the gate electrode. The protection layer covers at least a first portion of the top surface and the sidewall spacer. The protection layer is interposed between the interconnect plug and the gate electrode.

Abstract: A geotextile tube includes a bag unit, an extending unit, a main stitch seam, and two auxiliary stitch seams. The bag unit includes a tubular wall and an end wall cooperatively defining a filling space. The extending unit includes two extending parts respectively extending from opposite lateral sides of the end wall and each defining a buffering space. The main stitch seam extends from one of the extending parts to the other one of the extending parts for sealing the filling space. The auxiliary stitch seams intersect the main stitch seam, and are respectively disposed at the lateral sides of the end wall such that the end wall is substantially flat. Each auxiliary stitch seam separates an adjacent buffering space from the filling space.

Abstract: A multi-function lubricating oil feeding machine control apparatus is provided that responds to different conditions, and includes an oil feeding machine having a controller mounted thereon. The controller comprises a power supply circuit, a microprocessing unit, a multiplex scanning circuit, a motor drive circuit, a status display circuit, an external status input interface circuit, a status output interface circuit, and a function setting circuit. The oil feeding machine may be set for intermittent feeding of oil according to a set time value, or a number of rotations of the work machine, or to feed oil after the starting of the work machine. Additionally, the previous time value or number of rotations may be memorized and accumulated in the next count, so that feeding may start after a specific value or number of rotations has been reached.
