  • Publication number: 20240113172
    Abstract: A semiconductor device includes a substrate, a channel layer, a gate structure, source/drain regions, and an insulating layer. The channel layer is disposed over the substrate. The gate structure is disposed over the channel layer. The source/drain regions are disposed over the substrate and disposed at two opposite sides of the channel layer. The insulating layer is disposed between the channel layer and the source/drain regions.

  • Patent number: 11915359
    Abstract: Systems, apparatuses, and methods for implementing kernel software driven color remapping of rendered primary surfaces are disclosed. A system includes at least a general processor, a graphics processor, and a memory. The general processor executes a user-mode application, a user-mode driver, and a kernel-mode driver. A primary surface is rendered on the graphics processor on behalf of the user-mode application. The primary surface is stored in memory locations allocated for the primary surface by the user-mode driver and the kernel-mode driver is notified when the primary surface is ready to be displayed. Rather than displaying the primary surface, the kernel-mode driver causes the pixels of the primary surface to be remapped on the graphics processor using a selected lookup table (LUT) so as to generate a remapped surface which stored in memory locations allocated for the remapped surface by the user-mode driver. Then, the remapped surface is displayed.

  • Publication number: 20240036080
    Abstract: Disclosed are an analog quantity acquisition method and apparatus. An acquisition circuit with a zero flux current transformer is first used to acquire a current signal, where the acquisition circuit with the zero flux current transformer includes the zero flux current transformer, a compensating winding, and a dynamic detection unit, and the compensating winding generates a reverse excitation potential to counteract an excitation current and eliminate impacts of a ratio error and a phase angle error on accuracy. A multi-segment amplification circuit is used to perform segmented amplification on different ranges of the current signal, and full-range current acquisition is achieved by using different amplification circuits. An analog-to-digital converter chip is used to convert an amplified current signal into a digital signal. The acquisition circuit with the zero flux current transformer is used to eliminate the impacts of the ratio error and the phase angle error on the measurement accuracy.

  • Patent number: 11513030
    Abstract: The present disclosure provides a tidal simulation test device and a method of use thereof. The tidal simulation test device includes a water supply pool, a water level adjustment pool, a subtidal zone simulation pool, an intertidal zone simulation pool, a supratidal zone simulation pool and a two-way water flow adjustment control box. The two-way water flow adjustment control box is provided therein with an electromagnetic flow control meter, a forward frequency conversion self-priming pump, a reverse frequency conversion self-priming pump and an intelligent time-controlled three-way controller. In the method, the start and stop of the forward frequency conversion self-priming pump and the reverse frequency conversion self-priming pump are controlled through an intelligent switch, and a water flow is adjusted through the electromagnetic flow control meter, thereby realizing periodic changes in a water level to simulate different types of tides and coastal wetlands.
