Abstract
In one aspect, an apparatus is described that includes a transparent pane having a first surface and a second surface. An electrochromic device is arranged over the second surface that includes a first conductive layer adjacent the second surface, a second conductive layer, and an electrochromic layer between the first and the second conductive layers. The apparatus further includes at least one conductive antenna structure arranged over the second surface.
Claims22
A method of delivering power by wireless transmission to an electrochromic device, the method comprising:
- (a) determining that power is to be delivered to the electrochromic device via one or more first receivers, each comprising one or more first antennas;
- (b) causing a transmitter to wirelessly transmit power by electromagnetic transmission to the one or more first antennas, wherein the one or more first antennas are disposed (i) on one or more electrochromic windows including the electrochromic device and/or (ii) on one or more window controllers configured to control the electrochromic device, wherein the one or more electrochromic windows and/or on one or more window controllers are disposed in a building;
- and
- (c) receiving the wirelessly transmitted power at one or more of the first receivers using the one or more first antennas.
A system for delivering power by wireless transmission to an electrochromic device, the system comprising:
- a transmitter to wirelessly transmit power by electromagnetic transmission;
- one or more first receivers, each comprising one or more first antennas, wherein the one or more first antennas are disposed (i) on one or more electrochromic windows including the electrochromic device and/or (ii) on one or more window controllers configured to control the electrochromic device;
- and
- one or more logic devices configured or programmed to:
- (a) determine that power is to be delivered to the electrochromic device via one or more first receivers, and
- (b) cause the transmitter to wirelessly transmit power by electromagnetic transmission to one or more of the first antennas.
An apparatus comprising:
- one or more transparent lites comprising a first surface and a second surface;
- an electrochromic device (ECD) disposed on a first surface of the one or more lites and including:
- a first conductive layer adjacent the second surface,
- a second conductive layer, and
- an electrochromic layer between the first and the second conductive layers;
- at least one conductive antenna structure arranged over the first surface or a second surface of the one or more lites;
- and
- an electromagnetic shield comprising at least one electroconductive layer, with at least one adjacent antireflective layer, the shield being located between or adjacent to the first surface, the second surface, or another surface of the one or more lites.
An insulated glass unit (IGU) comprising an electrochromic device coating and a shielding stack comprising a metal layer, wherein the shielding stack is configured to block electromagnetic radiation by grounding the metal layer.
