Abstract: A memory device is provided. The memory device includes a write pass-gate transistor, a read pass-gate transistor, a write word line, and a read word line. The write pass-gate transistor is disposed in a first layer. The read pass-gate transistor is disposed in a second layer above the first layer. The write word line is disposed in a metallization layer above the first layer and electrically coupled to the write pass-gate transistor through a write path. The read word line is disposed in the metallization layer and electrically coupled to the read pass-gate transistor through a read path. The write path is different from the read path.

Abstract: A method includes forming a first sacrificial layer over a substrate, and forming a sandwich structure over the first sacrificial layer. The sandwich structure includes a first isolation layer, a two-dimensional material over the first isolation layer, and a second isolation layer over the two-dimensional material. The method further includes forming a second sacrificial layer over the sandwich structure, forming a first source/drain region and a second source/drain region on opposing ends of, and contacting sidewalls of, the two-dimensional material, removing the first sacrificial layer and the second sacrificial layer to generate spaces, and forming a gate stack filling the spaces.

Abstract: A semiconductor device includes a gate layer, a channel material layer, a first dielectric layer and source/drain terminals. The gate layer is disposed over a substrate. The channel material layer is disposed over the gate layer, where a material of the channel material layer includes a first low dimensional material. The first dielectric layer is between the gate layer and the channel material layer. The source/drain terminals are in contact with the channel material layer, where the channel material layer is at least partially disposed between the source/drain terminals and over the gate layer, and the gate layer is disposed between the substrate and the source/drain terminals.

Abstract: A circular saw includes a housing, a sawing assembly including a motor and a saw blade located at two opposite sides of the housing and connected together so that the saw blasé can be driven by the motor to saw the workpiece and a saw blade shield secured to the housing and covering a part of the saw blade to prevent the saw blade from cutting the surrounding people, and a prism assembly including a protective cover affixed to the front end of the saw blade shield and a prism located in the protective cover to reflect the image of the saw blade sawing the workpiece through a window of the protective cover to the line of sight of the operator. In this way, the operator can clearly confirm whether the sawing path is skewed with the normal operating posture to improve the efficiency.

Abstract: A smart home includes Internet of things (IOT) devices that are paired with an IOT gateway. A backend system is in communication with the IOT gateway to receive IOT operating data of the IOT devices. The backend system generates a machine learning model for an IOT device. The machine learning model is consulted with IOT operating data of the IOT device to detect anomalous operating behavior of the IOT device. The machine learning model is updated as more and newer IOT operating data of the IOT device are received by the backend system.

Abstract: A rotary worktable positioning structure used in a miter saw is disclosed to include a first positioning unit controllable by biasing a handle to lock the worktable to the machine base or to unlock the worktable for free rotation, and a second positioning unit controllable by rotating a switching wheel to move a lock pin into one of a number of locating holes on the periphery of the machine base and to further lock the worktable in one of a number of predetermined cutting angles.

Abstract: A miter saw having a securable positioning structure for a blade guard thereof includes a saw blade, a rotatable handle, a movable blade guard, a control unit, a positioning unit, and a rope. The rotatable handle is provided for the user's holding for the cutting operation. The movable blade guard is shiftable between where it covers the saw blade and where it does not cover the saw blade. The control unit is mounted to the rotatable handle. The positioning unit is provided for blocking the movement of the movable blade guard. The rope is connected with the control unit and the positioning unit. Accordingly, the user only needs to operate the control unit to drive action of the positioning unit via the rope to hold the movable blade guard in position, thus securing the safety of the operation. In addition, the rotatable handle can be turned smoothly without any barrier.

Abstract: A vise quick-release structure for a miter saw includes a base frame and at least one clamp. The clamp can be operated to move to and fro on the base frame, having pillars. The base frame has through holes each having portions having different widths. The pillars are inserted into the portions of the through holes respectively, whereby the clamp can only be forced to move to and fro in the portions of the through holes, such that the clamp can be quickly detached and installed with respect to the base frame.

Abstract: A wireless transceiving module includes an antenna, a signal processing unit and a shielding case. The antenna is used for transceiving an RF signal, and has a signal point. The signal processing unit is coupled to the signal point for processing the RF signal, and has an RF circuit coupled to the antenna and a baseband circuit for converting a first baseband signal into a first RF signal and for converting a second RF signal into a second baseband signal. The shielding case is used for electromagnetically shielding the signal processing unit, and the shielding case acts as a ground plane for the antenna.
