Abstract: A method for determining a standard depth value of a marker includes obtaining a maximum depth value of the marker. A reference depth value of the marker is obtained based on a depth image of the marker, and a Z-axis coordinate value of the marker is obtained based on a color image of the marker. When the reference depth value and the Z-axis coordinate value are both less than the maximum depth value, and a difference between the reference depth value and the Z-axis coordinate value is not greater than 0, the depth reference value is set as the standard depth value of the marker; and when the difference is greater than 0, the Z-axis coordinate value is set as the standard depth value of the marker.

Abstract: A light source device, including a first light source, providing a first light beam in a first time period of a first period; and a second light source, providing a second light beam in a second time period of the first period, is provided. The first light beam and the second light beam have the same color temperature. The first light beam and the second light beam are emitted alternately in the first period, and a color rendering index of mixed light of the first light beam and the second light beam is greater than or equal to 85.

Abstract: A floor faucet structure contains: a body, an adjustable fitting sleeve, a fixing seat, and a connection sleeve. The body includes a positioning disc, a cold-water inlet tube, and a hot-water inlet. Each of the cold-water inlet tube and the hot-water inlet tube has a respective one rotation members and a respective one connector. The respective one rotation member has a longitudinal extension, a horizontal extension, and a first conduit. The respective one connector includes a first connecting section, a second connecting section, a second conduit, at least one stop ring, a first external threaded section, and a second external threaded section. The adjustable fitting sleeve includes a first coupling portion, the fixing seat includes a circular groove, multiple retaining ribs. The connection sleeve includes a second coupling portion, a cylindrical fence, and multiple locking ribs.

Abstract: A floor faucet structure contains: a body, an adjustable fitting sleeve, a fixing seat, and a connection sleeve. The body includes a positioning disc having multiple orifices. The body further includes a cold-water inlet tube and a hot-water inlet, the two rotation members connect with two connectors individually, and the two connectors are perpendicular to the cold-water inlet tube and the hot-water inlet tube separately. The adjustable fitting sleeve includes a first coupling portion, the fixing seat includes a circular groove having multiple through holes, and the fixing seat includes multiple retaining ribs. The connection sleeve includes a second coupling portion configured to connect with the first coupling portion of the body, and the connection sleeve also includes a cylindrical fence on which two opposite cutouts are formed. The connection sleeve further includes multiple locking ribs configured to retain with the multiple retaining ribs of the fixing seat respectively.

Abstract: A drainage overflow pipe structure for a bathtub, wherein an overflow pipe of the drainage overflow pipe structure is mounted on a bathtub, and the drainage overflow pipe contains: a tee part, a drainage part, an overflow part, a pipe elbow, and a universal rotation assembly. The tee part includes a first coupling orifice, a second coupling orifice, and a third coupling orifice. The drainage part is connected with the first coupling orifice and the drainage hole. The overflow part includes a joining section and a connecting seat which has outer threads and a groove-shaped holding portion. The pipe elbow includes an inlet and an outlet. The universal rotation assembly includes a connector and a limitation member, wherein the connector has a screwing portion, a spherical knob, and a through orifice, and the limitation member includes inner threads.

Abstract: A cleaning device includes a handle with a longitudinal passage defined therethrough and a hollow shaft is connected to an end of the handle whose the other end is connected to a hose. A valve assembly is connected to the handle and a lower end of the valve assembly removably seals the passage in the handle. A nozzle device is pivotally connected to the hollow shaft so that cleaning agent from the hose is injected from the nozzle device. A connection tube is connected to the hollow shaft and a sponge assembly is connected to the connection tube.

Abstract: A sponge mop includes a post extending through a top of a frame and the frame has two extensions on each of which a roller is connected. A sponge is located between the two rollers. A lever handle is pivotally connected to the post and a link is fixedly connected between the lever handle and the ridge. A tank is connected to the post and receives cleaning detergent therein. An outlet extends from a lower end of the tank and is engaged with the hole in the frame. A seal member is removably engaged with the outlet and a control assembly is received in the tank. A lower end of the control assembly is connected to the seal member and an operation handle on a top of the control assembly is engaged with the top hole so that when rotating the operation handle, the detergent flows to the sponge.

Abstract: A sponge mop includes a handle having an assembly frame connected to a lower end thereof and a cleaning tank is connected to the assembly frame. The assembly frame has two separated parts and each part having a roller connected thereto so that a sponge is connected between the two rollers. A lever member is pivotally connected to the handle and two siderails are connected between the sponge and the lever member. A valve is connected between the cleaning tank and the sponge so that when operating the valve to an open position, the detergent in the tank flows to the sponge.
