  • Windows provide views, daylighting, ventilation, and heat from the sun in the winter. Unfortunately, they can also account for 10% to 25% of a home heating bill by letting heat out. Whilst some building codes limit the amount of window space in a wall or building, the use of glass in modern buildings is increasing.

  • Each window panel can be made from any material or combination of materials. It can be any type of window panel and any number of window panels used in a window assembly dependent only on the window configuration.
  • the window assembly of the present invention is a window that is power driven between the open and closed condition but this is not strictly necessary as the principles of the present invention can be incorporated into a window assembly which is opened and closed manually.
  • a particularly preferred window assembly according to the present invention is a louvre window assembly which is commonly referred to in the United States as a "jalousie”.
  • the preferred louvre window assembly includes a number of louvre blades within the surround frame.

  • the end clips are normally mounted for rotation (except fixed louvre blades) relative to a channel member provided on either end of the louvre blades.
  • a bearing is typically provided for each louvre blade end clip to engage with one or more elongate operating bars provided in the channel member such that linear movement of the operating bars will typically rotate at the bearing, which rotates the end clip thereby moving the louvre blade between the open and closed condition.
  • the bearings are normally mounted approximately centrally on the louvre blade end clip.
  • a louvre blade end clip is preferably used to mount the louvre blades relative to the surround frame. As will be clear, a different configuration of window panel mount will be used for windows having a different configuration.
  • Each louvre blade end clip normally has a louvre blade receiving opening and this receiving opening typically extend substantially of the height or length of the louvre blade end clip. Normally, the louvre blade receiving opening is provided approximately centrally across the louvre blade end clip. Typically, the shaped wall is provided to either side of the louvre blade receiving opening which defines the external shape of the end clip as viewed by a user.
  • the louvre blade receiving opening is normally substantially U-shaped with a pair of spaced apart side walls between which the blade is received and a base wall extending transversely between the spaced apart side walls and relative to which the end edge of the louvre blade is typically located.
  • the spaced apart side walls normally receive the louvre blade closely therebetween.
  • a transverse pin or similar may be provided through an opening formed in one of the shaped walls, through both side walls of the blade receiving opening (end through an opening in the louvre blade) in order to fix the louvre blade relative to the end clip.

  • An opening is normally provided through one of the walls of the channel through which a bearing can engage the end clip both mounting the end clip to the channel and allowing rotation of the end clip to be driven by components located in the channel.
  • the window panel mount provided for the window panels in the window assemblies of other configurations is preferably similar to the louvre blade end clip in that a window panel receiving opening is preferably defined on a least one side of the window panel in order to receive a portion of the or each window panel.
  • the window panel mount includes at least one electrical contact to interface with an electrical component provided with or carried by the window panel and electrical subsystem provided within or outside the surround frame.
  • the electrical component provided with or carried by the window panel may be provided as a part of the window panel itself or onto the window panel.
  • the electrical component can be or include a surface film or similar of which there are various types currently available.
  • the electrical component can be provided as the window panel itself for example, a touchscreen or display screen or similar can be provided as the window panel.
  • An electrical component can be provided on some or all of the window panels.
  • window panels can have different electrical components provided on different window panels or more than one electrical component can be provided on any one window panel.
  • one louvre blade in a louvre window assembly may be designated as a control blade and provide an input or control interface to control the louvre window assembly or functionality associated therewith on the louvre blade itself.
  • the input or control interface will be provided with another electrical component provided on the same blade.
  • the input of control interface may be provided on a different portion of the louvre blade to the electrical component.
  • the input or control interface can be provided on an inner surface of the louvre blade and the electrical component can be provided on the outer surface as this may minimise disruption between the two components.
  • ancillary functionality that can be provided using an electrical component is smart glass or switchable glass which is glass or glazing whose light transmission properties are altered when voltage, light or heat is applied. Generally, the glass changes from translucent to transparent, changing from blocking some (or all) wavelengths of light to letting ;ht pass through.
  • Smart glass technologies include electrochromic, photochromic, thermochromic, suspended particle, micro-blind and liquid crystal devices.
  • Electrochromic devices change light transmission properties in response to voltage and thus allow control over the amount of light and heat passing through.
  • the electrochromic material changes its opacity: it changes between a coloured, translucent state (usually blue) and a transparent state.
  • a burst of electricity is required for changing its opacity, but once the change has been effected, no electricity is needed for maintaining the particular shade which has been reached.
  • Darkening occurs from the edges, moving inward, and can be a relatively slow process, ranging from many seconds to several minutes depending on size.
  • Electrochromic glass provides visibility even in the darkened state and thus preserves visible contact with the outside environment.
  • the single substrate display structure consists of several stacked porous layers printed on top of each other on a substrate modified with a transparent conductor (such as ITO or PEDOT:PSS). Each printed layer has a specific set of functions.
  • a working electrode consists of a positive porous semiconductor (say Titanium Dioxide, Ti0 2 ) with adsorbed chromogens (different chromogens for different colours). These chromogens change colour by reduction or oxidation.
  • a passivator is used as the negative of the image to improve electrical performance.
  • the insulator layer serves the purpose of increasing the contrast ratio and separating the working electrode electrically from the counter electrode.
  • the counter electrode provides a high capacitance to counterbalances the charge inserted/extracted on the SEG electrode (and maintain overall device charge neutrality).
  • Carbon is an example of charge reservoir film.
  • a conducting carbon layer is typically used as the conductive back contact for the counter electrode.
  • the porous monolith structure is overprinted with a liquid or polymer-gel electrolyte, dried, and then may be incorporated into various encapsulation or enclosures, depending on the application requirements. Displays are very thin, typically 30 micrometer, or about 1/3 of a human hair.
  • the device can be switched on by applying an electrical potential to the transparent conducting substrate relative to the conductive carbon layer. This causes a reduction of viologen molecules (coloration) to occur inside the working electrode.
  • the device bleaches.
  • a unique feature of the electrochromic monolith is the relatively low voltage (around 1 Volt) needed to colour or bleach the viologens. This can be explained by the small over- potentials needed to drive the electrochemical reduction of the surface adsorbed viologens/chromogens.
  • liquid crystals are dissolved or dispersed into a liquid polymer followed by solidification or curing of the polymer.
  • the liquid crystals become incompatible with the solid polymer and form droplets throughout the solid polymer.
  • the curing conditions affect the size of the droplets that in turn affect the final operating properties of the "smart window".
  • the liquid mix of polymer and liquid crystals is placed between two layers of glass or plastic that include a thin layer of a transparent, conductive material followed by curing of the polymer, thereby forming the basic sandwich structure of the smart window. This structure is in effect a capacitor.
  • Electrodes from a power supply are attached to the transparent electrodes. With no applied voltage, the liquid crystals are randomly arranged in the droplets, resulting in scattering of light as it passes through the smart window assembly. This results in the translucent, "milky white” appearance.
  • a voltage is applied to the electrodes, the electric field formed between the two transparent electrodes on the glass causes the liquid crystals to align, allowing light to pass through the droplets with very little scattering and resulting in a transparent state.
  • the degree of transparency can be controlled by the applied voltage. This is possible because at lower voltages, only a few of the liquid crystals align completely in the electric field, so only a small portion of the light passes through while most of the light is scattered.
  • a thin-film solar cell can be provided as the electrical component.
  • These cells are second generation solar cells that are made by depositing one or more thin layers, or thin film (TF) of photovoltaic material on a substrate, such as glass, plastic or metal.
  • Thin-film solar cells are commercially used in several technologies, including cadmium telluride (CdTe), copper indium gallium diselenide (CIGS), and amorphous thin-film silicon (a-Si, TF-Si).
  • Photovoltaic cells include, organic, dye- sensitized, and polymer solar cells, as well as quantum dot, copper zinc tin sulfide, nanocrystal, micromorph and perovskite solar cells.
  • the electrical subsystem corresponding to the electrical component provided on or carried by the window panel is preferably provided in the surround frame but may be provided outside the surround frame or even remotely from the surround frame.
  • the electrical subsystem will typically be appropriate to the electrical component provided on or carried by the window panel.
  • At least one electrical contact is provided in the window panel mount to interface with the electrical component and the electrical subsystem.
  • the at least one electrical contact may allow current and/or data to be passed between the electrical component and the electrical subsystem.
  • the exact nature of whether current and/or data flows depends upon the particular nature of the electrical component provided. For example, a photovoltaic film applied to a window panel will typically mean that current flows from the window panel to a storage subsystem or the agreed. If the window panel is or includes switchable glass, current will typically flow from a current supply subsystem to the window panel. If the window panel is display enabled, then current will normally flow to the window panel and data may flow to the window panel as well. Where the window panel is an interactive enabled window panel, current will typically flow to the window panel and data may flow to and from the window panel.
  • the least one electrical contact is provided in the window panel mount and in the preferred embodiment discussed above of a louvre window assembly, the at least one electrical contact is provided in at least one of the louvre blade end clips in order to form a connection between the electrical component provided with or carried by the louvre blade and the corresponding electrical subsystem.
  • at least one contact is provided in the louvre blade receiving opening.
  • an electrical contact is provided at least partially over the at least one sidewall of the louvre blade receiving opening and/or at least partially over the at least one base wall of the louvre blade receiving opening. The exact position and extent of the electrical contact will in large part be determined by the particular electrical component carried by or provided on the louvre blade. Any type of contact can be provided which allows current and/or data flow.
  • Appropriate connections are provided between the at least one electrical contact provided in the window panel mount and the electrical subsystem.
  • a ribbon or flexible PCB or similar will be provided.
  • the ribbon or flexible PCB will enter the preferred louvre blade end clip through the bearing provided.
  • the ribbon or flexible PCB connection will be located coaxially with the axis of rotation of the louvre blade end clip which will normally limit the potential for damage to the ribbon or flexible PCB.
  • the ribbon or flexible PCB will extend at least into the louvre blade end clip through the base wall of the louvre blade receiving opening in order to access the at least one electrical contact located in the louvre blade receiving opening.
  • the window assembly of the preferred embodiment will normally have a main wiring bus, preferably provided in at least one of the surround frame members in order to connect with the ribbons or flexible PCBs from each of the end clips.

  • the electrical subsystem may be provided within the surround frame if small enough.
  • a battery which is charged using electrical current generated from a solar cell or PV film provided on a window panel.
  • Such a battery can be used for storage of electrical current to allow an electrical motor to open and close the window assembly or to power one or more sensors in the window assembly to create a standalone window assembly which is not connected to mains power.
  • a battery can be provided in one of the surround frame members.
  • the electrical subsystem or portions thereof can be provided outside the window assembly if larger and more complex. More complex systems such as display active or displayed interactive window panels, or touchscreens window panels may require at least portions of the electrical subsystem to powering control the systems, externally of the window frame. Some technologies, such as touchscreens or biometric activation, are currently available and the electrical subsystems to drive these may be small enough to locate in the surround frame.
  • a louvre window assembly can be provided as a display screen with a touchscreen interface functioning similarly to a tablet or smart phone screen with a data connection provided in the window assembly in order to allow a user to use the louvre window (typically when closed) as a tablet computer or the like.
  • Window assemblies of the present invention can be used to display or convey patterns or messages or to provide switchable privacy glass or tinted glass for example.
  • a window assembly according to the present invention can be used as a PV collector through the application of PV film to an external surface of the window panel.
  • Combinations of electrical components on the louvre blades can be used either on the same louvre blades within the system or different electrical components provided on different louvre blades in the same system.
  • the louvre blade system can provide more flexibility than other window configurations which typically have a limited number of window panels which can be used, sometimes only the one panel which although well configured to function as a display screen for example, may not be flexible enough to handle different combinations of electrical components on the same window panel.
