[0009] The control system 1 is a system that controls devices in one or more buildings 2. The building 2 is, for example, a detached house, an apartment building, an office building, a factory, a hospital, a commercial facility, a public facility, or any other type of facility or building. The building 2 may be a part of a single building. The part of a building is, for example, a room in a building. The control system 1 includes, for example, a window 100, a power transmission device 200, and a control device 300.

[0010] The window 100 will be described with reference to Figs. 1 to 4. Fig. 2 is a plan view showing an example of the window 100 according to the embodiment. Fig. 3 is a perspective view showing an example of the window 100 according to the embodiment. Fig. 4 is a view showing an enlarged portion of Fig. 3. Figs. 2 to 4 are all views seen from the inside of the room. The window 100 shown in Figs. 2 to 4 is a sliding window. The window of the embodiment is not limited to a sliding window and may be various types of windows, but a sliding window will be described here as an example. The window 100 includes, as an example, an inner window frame 110, a window glass 120, a crescent 130, an outer window frame 140, a frame 150, a power receiving unit 160, and a load unit 170. The inner window frame 110, the window glass 120, the crescent 130, the outer window frame 140, and the frame 150 are each an example of a fitting part. The window 100 is also an example of a fitting.

[0011] The inner window frame 110 is a window frame into which the window glass 120 is fitted. The inner window frame 110 is also called a frame. Note that the inner window frame 110 shown in FIG. 1 is only a frame, but the inner window frame 110 may also include a sash. The inner window frame 110 is an example of a window frame. The inner window frame 110 is an example of a frame for fittings.

[0012] The inner window frame 110 can slide on a rail formed on the outer window frame 140, and thereby move along the rail. The window 100 includes, as an example, two inner window frames 110, an inner window frame 110A and an inner window frame 110B. The inner window frame 110A is generally the inner window frame 110 closer to the inside of the room. The inner window frame 110B is generally the inner window frame 110 closer to the outside of the room. The material of the inner window frame 110 is not limited, and may be, for example, metal, wood, resin, or a composite material. The material of the inner window frame 110 may be a conductive material or an insulating material.

[0013] The inner window frame 110 includes, as an example, an inner frame 111, an outer frame 112, an upper frame 113, and a lower frame 114.

[0014] The inner frame 111 and the outer frame 112 are frames that extend vertically at the left and right ends of the inner window frame 110. Of the inner frame 111 and the outer frame 112, the one closer to the center of the window 100 is the inner frame 111. Of the inner frame 111 and the outer frame 112, the one closer to the outside of the window 100 is the outer frame 112. The inner frame 111 is sometimes called a door frame. The outer frame 112 is sometimes called a vertical frame or a door end frame.

[0015] The upper frame 113 is a frame that extends horizontally at the upper end of the inner window frame 110. The upper frame 113 is sometimes called an upper frame.

[0016] The sill 114 is a frame that extends horizontally at the lower end of the inner window frame 110. The sill 114 is sometimes called a bottom frame.

[0017] The inner frame 111, outer frame 112, upper frame 113, and lower frame 114 of the inner window frame 110A will be referred to as the inner frame 111A, outer frame 112A, upper frame 113A, and lower frame 114A. The inner frame 111, outer frame 112, upper frame 113, and lower frame 114 of the inner window frame 110B will be referred to as the inner frame 111B, outer frame 112B, upper frame 113B, and lower frame 114B.

[0018] The window glass 120 is a piece of window glass that is fitted into the inner window frame 110. The window glass 120 is not limited to glass and may be made of resin. The window glass 120 may also be provided with a sheet or film having various functions.

[0019] The crescent 130 is attached to the inner window frame 110A and the inner window frame 110B. The crescent 130 is a component for locking the window 100. The crescent 130 includes, for example, a base 131, a crescent fitting 132, a handle 133, and a crescent receiver 134.

[0020] The base 131 is the part that is attached to the inner window frame 110A.

[0021] The crescent fitting 132 and the handle 133 are rotatably attached to the base 131. The crescent fitting 132 is a fitting for fitting into the crescent receiver 134.

[0022] The handle 133 is a handle for holding the crescent fitting 132 when rotating it.

[0023] The crescent receiver 134 is attached to the inner window frame 110B. The crescent receiver 134 is a component for locking the window 100. The crescent 130 allows the window 100 to be locked by fitting the crescent fitting 132 into the crescent receiver 134 by rotating the crescent fitting 132 and the handle 133.

[0024] The outer window frame 140 is a window frame that surrounds the two inner window frames 110. The outer window frame 140 surrounds the two inner window frames 110 in a movably manner. The outer window frame 140 is formed with a rail along which the inner window frames 110 move. The outer window frame 140 is fixed to a picture frame 150. The material of the outer window frame 140 may be a conductive material or an insulating material. The outer window frame 140 is an example of a window frame. The outer window frame 140 is an example of a frame for fittings.

[0025] The frame 150 is a building material that surrounds the outer window frame 140. The frame 150 is fixed to a wall, ceiling, or roof of the building 2. Note that multiple outer window frames 140 may be fixed within the frame 150. The material of the frame 150 may be a conductive material or an insulating material. The frame 150 is an example of a window frame. The frame 150 is an example of a frame for fittings.

[0026] The power receiving unit 160 is a circuit or device that receives radio waves and converts them into electric power. The radio waves are transmitted from a power transmitting device, for example. The power receiving unit 160 includes an antenna 161 and a rectifier circuit 162, for example.

[0027] The antenna 161 receives radio waves. As an example, the antenna 161 is present on the surface of the inner window frame 110 and inside the crescent 130. The antenna 161 of the inner window frame 110 and the antenna 161 inside the crescent 130 are electrically connected. When the material of the inner window frame 110 is a conductive material, the antenna 161 is, for example, an uneven pattern formed on the surface of the inner window frame 110 as shown in FIG. 4. When the material of the inner window frame 110 is a conductive material, the inner window frame 110 in a portion where the uneven pattern is not formed also functions as an antenna. When the material of the inner window frame 110 is an insulating material, the antenna 161 is, for example, an antenna attached to the surface of the inner window frame 110. The antenna 161 is, for example, attached to the surface of the inner window frame 110 in the form of a sheet or film on which an antenna pattern is formed. Even when the material of the inner window frame 110 is not an insulating material, the antenna 161 may be an antenna attached to the surface of the inner window frame 110. The antenna 161 may be provided in both the inner window frame 110A and the inner window frame 110B. When both the inner window frame 110A and the inner window frame 110B are provided with the antenna 161, the antenna 161 of the inner window frame 110A and the antenna 161 of the inner window frame 110B are electrically connected. Preferably, the inner window frame 110A is provided with the antenna 161. Note that the inner window frame 110 is provided with the antenna 161 in at least one of the inner frame 111, the outer frame 112, the upper frame 113, and the lower frame 114. In Figs. 3 and 4, the inner frame 111A is provided with the antenna 161. Also, the antenna 161 may be embedded inside the inner window frame 110.

[0028] The crescent 130 includes, for example, an antenna 161 inside the handle 133. Fig. 5 is a perspective view showing an example of the inside of the handle 133. Note that Fig. 5 shows only the cover portion of the handle 133. As shown in Fig. 5, the handle 133 includes an antenna 161 inside. The antenna 161 inside the handle 133 is, for example, an antenna formed on a sheet or film.

[0029] The crescent 130 may include the antenna 161 inside the base 131, not limited to the handle 133. The crescent 130 may include the antenna 161 inside both the base 131 and the handle 133. The crescent 130 may include the antenna 161 in a portion other than the base 131 and the handle 133. The crescent 130 may include the antenna 161 on its surface, not limited to its interior. The antenna 161 on the surface of the crescent 130 may be an uneven pattern formed on the surface of a conductive material, similar to the inner window frame 110.

[0030] The rectifier circuit 162 converts the radio waves received by the antenna 161 into electric power. The rectifier circuit 162 converts the radio waves received by the antenna 161 into, for example, direct current. The rectifier circuit 162 is an example of a conversion unit that converts the radio waves received by the fitting component into electric power.

[0031] The power receiving unit 160 is, for example, a circuit in which an antenna 161 and a rectifier circuit 162 exist separately. In this case, for example, the crescent 130 includes therein the rectifier circuit 162. Alternatively, the inner window frame 110, the crescent receiver 134, the outer window frame 140, or the frame 150 may include therein the rectifier circuit 162.

[0032] The power receiving unit 160 may be a rectenna in which the antenna 161 and the rectifier circuit 162 are integrated together.

[0033] The load unit 170 includes at least one of a circuit and a device that consumes the power output by the power receiving unit 160. The load unit 170 operates using the power output by the power receiving unit 160. The load unit 170 includes, for example, a control unit 171, a sensor 172, and a communication unit 173. For example, the crescent 130 includes a part or all of the load unit 170 therein. The inner window frame 110, the crescent receiver 134, the outer window frame 140, or the frame 150 may include a part or all of the load unit 170 therein.

[0034] The control unit 171 is a computer that performs processes such as calculations and controls required for the operation of the load unit 170. The control unit 171 controls the sensor 172 and the communication unit 173.

[0035] The sensor 172 is, for example, a sensor that detects whether the window 100 is opened or closed, a sensor that detects brightness, a sensor that detects temperature, or another sensor. The load unit 170 may be provided with a plurality of types of sensors 172.

[0036] The communication unit 173 includes an antenna for wireless communication. The communication unit performs wireless communication based on the control by the control unit. For example, the communication unit 173 transmits a signal including a measurement result of the sensor 172 to the control device 300. The communication unit 173 also receives a signal including a command to the control unit 183 transmitted from the control device 300.

[0037] The load section 170 may include at least one of other circuits and devices that consume power. The load section 170 includes, for example, a light control device as a device that consumes power. In this case, the window glass 120 includes a light control sheet. The light control sheet is a sheet or film having liquid crystal molecules therein. The light control device controls the orientation of the liquid crystal molecules in the light control sheet by applying a voltage to the light control sheet. The transparency of the light control sheet changes as the orientation of the liquid crystal molecules changes. In this way, the light control device changes the transparency of the light control sheet. In other words, the light control device changes the transparency of the window glass 120.

[0038] The load unit 170 may include a locking device as another device that consumes power. The locking device is a device that uses power to at least either lock or unlock the window 100.

[0039] The power transmitting device 200 converts electric power into radio waves such as microwaves and transmits the radio waves from an antenna. The power transmitting device 200 transmits the radio waves toward the power receiving unit 160 in the window 100. The power transmitting device 200 is installed on the ceiling of the building 2, for example.

[0040] The control device 300 is a computer that performs processes such as calculations and controls required for the operation of the control system 1. The control device 300 is, for example, a control device for a smart house. The control device 300 is, for example, a control device for building management. Alternatively, the control device 300 may be a smartphone, a tablet terminal, a PC (personal computer), a server, or the like. The control device 300 controls the window 100 and the power transmitting device 200.

[0041] The window 100 of the embodiment receives radio waves using the window frame as an antenna. This allows the window 100 of the embodiment to receive radio waves with high efficiency because it uses a larger antenna than when the antenna 161 is only located inside the crescent 130.

[0042] Furthermore, if the antenna 161 is located only within the crescent 130, the characteristics of the antenna 161 may change due to the influence of the window frame, resulting in a decrease in reception sensitivity. In contrast, the window 100 of the embodiment receives radio waves using the window frame as an antenna, so it is possible to prevent the characteristics of the antenna 161 from changing due to the influence of the window frame, resulting in a decrease in reception sensitivity.

[0043] Moreover, in the window 100 of the embodiment, the inner window frame 110 is provided with the antenna 161. Since the crescent 130 is attached to the inner window frame 110, it is easy to electrically connect the circuit within the crescent 130, the inner window frame 110, and the antenna 161.

[0044] Furthermore, in the window 100 of the embodiment, in addition to the window frame, the crescent 130 is equipped with the antenna 161. It is therefore considered that the window 100 of the embodiment can receive radio waves more efficiently than when only the window frame is equipped with the antenna 161.

[0045] Furthermore, the window 100 of the embodiment includes a sensor 172. This enables the window 100 of the embodiment to perform various sensing operations using power transmitted by microwave power transmission.

[0046] The above embodiment can be modified as follows. The crescent 130 may not include the antenna 161 .

[0047] The window 100 may use the inner window frame 110 as an antenna without the antenna 161. In this case, the material of the inner window frame 110 is a conductive material. In addition, the inner window frame 110 in this case is electrically connected to the rectifier circuit 162. In the case where the window 100 includes the antenna 161, the antenna 161 and the inner window frame 110 are electrically connected.

[0048] The outer window frame 140 may be provided with an antenna 161. When the material of the outer window frame 140 is a conductive material, the antenna 161 provided on the outer window frame 140 is, for example, an uneven pattern formed on the surface of the outer window frame 140. When the material of the outer window frame 140 is a conductive material, the outer window frame 140 in a portion where the uneven pattern is not formed also functions as an antenna. When the material of the outer window frame 140 is an insulating material, the antenna 161 provided on the outer window frame 140 is an antenna attached to the surface of the outer window frame 140. When the material of the outer window frame 140 is not an insulating material, the antenna 161 provided on the outer window frame 140 may also be an antenna attached to the surface of the outer window frame 140. The antenna 161 provided on the outer window frame 140 is electrically connected to the rectifier circuit 162. When the window 100 includes an antenna 161 other than on the outer window frame 140, the antenna 161 other than on the outer window frame 140 and the antenna 161 on the outer window frame 140 are electrically connected.

[0049] The window 100 may use the outer window frame 140 as an antenna without the antenna 161. In this case, the material of the outer window frame 140 is a conductive material. In addition, in this case, the outer window frame 140 is electrically connected to the rectifier circuit 162. In the case where the window 100 includes the antenna 161, the antenna 161 and the outer window frame 140 are electrically connected.

[0050] The frame 150 may include an antenna 161. When the frame 150 is made of a conductive material, the antenna 161 of the frame 150 is, for example, an uneven pattern formed on the surface of the frame 150. When the frame 150 is made of a conductive material, the frame 150 in a portion where the uneven pattern is not formed also functions as an antenna. When the frame 150 is made of an insulating material, the antenna 161 of the frame 150 is an antenna attached to the surface of the frame 150. When the frame 150 is not made of an insulating material, the antenna 161 of the frame 150 may also be an antenna attached to the surface of the frame 150. The antenna 161 of the frame 150 is electrically connected to the rectifier circuit 162. When the window 100 includes the antenna 161 other than the frame 150, the antenna 161 of the frame 150 is electrically connected to the antenna 161 of the frame 150 other than the frame 150.

[0051] The window 100 may use a frame 150 without the antenna 161 as the antenna. In this case, the frame 150 is made of a conductive material. In addition, in this case, the frame 150 is electrically connected to the rectifier circuit 162. In the case where the window 100 includes the antenna 161, the antenna 161 and the frame 150 are electrically connected to each other.

[0052] The window glass 120 may be equipped with the antenna 161. The antenna 161 of the window glass 120 is electrically connected to an antenna 161 equipped on a component other than the window glass 120.

[0053] The window of the embodiment may include a window part other than the crescent 130 instead of or in addition to the crescent 130. Examples of the window part other than the crescent 130 include a cam latch handle, a cremone handle, an operator handle, and a locking handle. Examples of the window part other than the crescent 130 include a handle for opening and closing the window, a handle for locking the window, or a part for locking the window. The window of the embodiment may include a plurality of the window parts listed above. The window part other than the crescent 130 may include a part or all of the power receiving unit 160 and the load unit 170, similar to the crescent 130.

[0054] In the above embodiment, the window 100 is described as a sliding window. However, the window of the embodiment may be another type of window as described above. Other types of windows may include sliding windows, sash windows, tilting windows, casement windows, folding windows, projection windows, louver windows, awning windows, and pivot windows. Depending on the type of window, the window 100 does not include a crescent 130. Depending on the type of window, the window 100 includes a cam latch handle, a cremone handle, or an operator handle. Depending on the type of window, the window 100 may include a locking handle.

[0055] The window of the embodiment may be a fixed window. Fixed windows generally do not include the crescent 130 and the window components listed above. Fixed windows include an inner window frame 110, an outer window frame 140, and a frame 150 that include a power receiving unit 160 and a load unit 170. Note that fixed windows do not necessarily need to include at least one of the outer window frame 140 and the frame 150.

[0056] The window of the embodiment may include a screen. In this case, the screen may include an antenna 161. The screen may include a part or all of a conductive material. In this case, the conductive material may be the antenna 161. The antenna 161 included in the screen is electrically connected to a rectifier circuit 162. When the window of the embodiment includes an antenna 161 other than the screen, the antenna 161 other than the screen and the antenna 161 of the screen are electrically connected. The window of the embodiment may use a screen without an antenna 161 as an antenna. In this case, the material of the screen is a conductive material. In addition, in this case, the screen is electrically connected to a rectifier circuit 162. When the window of the embodiment includes an antenna 161, the antenna 161 and the screen are electrically connected.

[0057] The window of the embodiment may be equipped with a storm shutter. In this case, the storm shutter may be equipped with an antenna 161. A part or all of the mesh of the storm shutter may be made of a conductive material. In this case, the mesh made of a conductive material may be the antenna 161. The antenna 161 equipped on the storm shutter is electrically connected to a rectifier circuit 162. When the window of the embodiment is equipped with an antenna 161 other than the storm shutter, the antenna 161 other than the storm shutter and the antenna 161 of the storm shutter are electrically connected. The window of the embodiment may be one in which a storm shutter without an antenna 161 is used as an antenna. In this case, the material of the storm shutter is a conductive material. Also, in this case, the storm shutter is electrically connected to a rectifier circuit 162. Also, when the window of the embodiment is equipped with an antenna 161, the antenna 161 and the storm shutter are electrically connected.

[0058] The window 100 does not necessarily have to include the window glass 120. In this case, the window 100 may include a member that covers the portion that comes into contact with the window glass 120, instead of the window glass 120. The member is wood, metal, resin, a composite material, or other material. The member may be integrated with the inner window frame 110. A part or the whole of the antenna 161 may be formed on or attached to the member.

[0059] The window 100 may be a skylight. The window 100 may be a bay window.

[0060] The window 100 may include a power storage unit. The power storage unit is a secondary battery or a capacitor that stores the power output by the power receiving unit 160. The load unit 170 may operate using the power output by the power storage unit. For example, the crescent 130 may include a power storage unit therein. Alternatively, the inner window frame 110, the crescent receiver 134, the outer window frame 140, or the frame 150 may include a power storage unit therein.

[0061] In the above embodiment, a window has been taken as an example to explain the embodiment. However, the above embodiment is not limited to a window, and can also be applied to fittings other than windows. In this case, the fitting includes a power receiving unit 160 and a load unit 170. Fittings other than windows include doors, screen doors, storm shutters, shutters, and the like. By applying the above embodiment to fittings other than windows, the fittings can receive radio waves in microwave power transmission with high efficiency.

[0062] An embodiment will be described taking a door as an example of a fixture other than a window. Fig. 6 is a diagram showing an example of a door 400 according to the embodiment. The door 400 includes, as an example, a door frame 410, a door main body 420, a lock 430, and a door handle 440. The door frame 410, the door main body 420, the lock 430, and the door handle 440 are each an example of a fixture part.

[0063] The door frame 410 is an outer frame portion of the door body 420. The door frame 410 is an example of a frame for a fixture.

[0064] Door body 420 is a part that opens and closes. Door body 420 is an example of a fitting body.

[0065] The lock 430 is a component that locks the door 400 .

[0066] The door handle 440 is a handle to be gripped when opening or closing the door 400 .

[0067] The door 400 includes a power receiving unit 160, similar to the window 100. For example, at least one of the door frame 410, the door main body 420, the lock 430, and the door handle 440 includes an antenna 161.

[0068] When the material of the door frame 410 is a conductive material, the antenna 161 of the door frame 410 is, for example, an uneven pattern formed on the surface of the door frame 410. When the material of the door frame 410 is a conductive material, the part of the door frame 410 where the uneven pattern is not formed also functions as an antenna. When the material of the door frame 410 is an insulating material, the antenna 161 of the door frame 410 is an antenna attached to the surface of the door frame 410.
