Latest Patents

One of his latest patents is the "Gas detection module and gas sensor thereof." This invention provides a convenient detection mechanism for alcohol gas. The gas detection module includes a gas sensor and a detection circuit. The gas sensor is composed of a substrate, a gate, an insulating layer, an active layer, a source, and a drain. The gate is positioned on the substrate, while the insulating layer is placed on both the gate and the substrate. The active layer is situated on the insulating layer, with the source and drain partially arranged on the active layer and extending to the insulating layer. This design allows the active layer to be exposed between the source and the drain, and the detection circuit is electrically connected to the source of the gas sensor. This innovation effectively overcomes the deficiencies of conventional gas detection modules.

Another notable patent is the "Light sensing circuit and control method thereof." This invention addresses the issue of low reliability in illumination detection. It features a photo transistor with a gate, a drain, and a source. The circuit includes a first transistor that connects the gate and source of the photo transistor, along with a first capacitor linking the gate and drain. Additionally, a second transistor connects with the drain, the first capacitor, and a data signal. A second capacitor is also included, connecting the source of the photo transistor to a ground contact. The circuit is completed with a third transistor and a switch that alternates the connection of the third transistor with either a buffer or a zero signal. This innovative design ensures that the identified problems in light sensing are effectively resolved.
