Abstract: A diffuser includes a diffusing case having a rear side removably coupled to a main body of a hair dryer. Gas discharged from the main body is introduced into the diffusing case through a gas inlet hole defined at the rear side. The gas introduced into the diffusing case is discharged from a front side of the diffusing case. The diffusing case has a concave or curved structure such that an inner diameter of the diffusing case increases in a forward direction. A guide frame provided inside the diffusing case to guide a flow of the introduced gas includes a diffusion portion or protrusion provided to face the gas inlet hole to diffuse the gas introduced through the gas inlet hole.

Abstract: A smart entryway includes an entrance door assembly configured to allow users (e.g., residents) to enter and exit a first space (e.g., a residence) and a storage assembly configured to allow secondary users (e.g., deliverymen) in a second space (e.g., a porch) to store items for later retrieval by the users. A portion of the storage assembly may be optionally refrigerated or heated. A security assembly is provided between the entrance door assembly and the storage assembly. The security assembly includes an authentication device to authenticate users and secondary users and a locking device to unlock the storage assembly and the entrance door assembly upon authentication. The locking device is provided behind the authentication device and concealed from the second space. When a first door of the storage assembly accessible from the first space is opened, a second door of the storage assembly accessible from the second space is locked.

Abstract: Disclosed is a hair iron comprising: a pair of bodies each including a fixing portion and a driver rotatably coupled to one side of the fixing portion; and a hinge portion which is coupled to the other side of the fixing portion of the pair of bodies and adjusts the angle of the pair of bodies, wherein the driver comprises: a rotating plate coupled to one end of the fixing portion so as to be rotatable in a longitudinal direction from the other end of the fixing portion to the one end thereof, as a rotary shaft; a heating module located on one surface of the rotating plate; and a cooling module located on the other surface of the rotating plate. Accordingly, by simultaneously or sequentially applying a hot/cold process, thermal damage to hair may be minimized and setting power may be increased.

Abstract: A diffuser may include a diffusing case having a rear side removably coupled to a main body of a hair dryer. Fluid (such as gas or air) discharged from the main body is introduced into the diffusing case through an inlet hole defined at the rear side. The fluid introduced into the diffusing case is discharged to an outside through a front side of the diffusing case. A light irradiator may be provided inside the diffusing case to irradiate light toward the front side of the diffusing case. The light irradiator may include a plurality of light emitters arranged on a circuit board to emit light. Some of the plurality of light emitters may be spaced apart from others of the plurality of light emitters in a front-rear direction.

Abstract: Provided is a sensor comprising a non-conductive substrate; and a conductive layer electronically printed on one side of the substrate, wherein the conductive layer comprises: an antenna pattern for transmitting and receiving a radio signal with an external device; a sensing electrode connected to the antenna pattern via a circular wiring for sensing an impedance change due to contact with a sensing target material; and a coating electrode stacked on the sensing electrode for removing an occurrence of noise of the impedance change. Accordingly, the present invention solves the problem of a sensor, in the form of a terminal, not being compact and the problem of high manufacturing costs and low manufacturing quality of a sensor manufactured using a deposition method in order to replace such sensor with a sensor manufactured by a printing method, and solves a corrosion problem of a sensing electrode, a durability problem, etc. that may occur in the sensor of the printing method.
