  • This invention relates to a light transmitting arrangement.
  • One embodiment of the invention comprises a window incorporated in a building or other permanent structure.
  • Other embodiments of the invention may comprise windows in other arrangements, e.g. in a motor vehicle or in a pair of sunglasses.
  • Windows are usually associated with curtains or blinds to be used when it is desired to provide a degree of privacy within a room provided with the window, or when it is desired to prevent bright sunshine from shining into people's eyes or damaging furniture or other items within the room provided with the win ⁇ ow.
  • Such curtains or blinds may, in certain circumstances, be subjected to vandalism. Also, the degree of control over the opening and closing of such curtains or blinds is very restricted.
  • Windows incorporating liquid crystal devices for adjusting their opacity are also known. However, these tend to be controlled simply by means of a manual control or a single light sensor.
  • the present invention seeks to provide an improved light transmitting arrangement which provides for a greater range of transparency adjustments and more sophisticated control of the adjustment than known arrangements.
  • a light transmitting arrangement comprising a window provided with adjustment means for adjusting the opacity of the window and control means for controlling operation of the adjustment means, the control means being arranged to operate in dependence a signal from input means, other than just the output of a manual control or the output of a single lignt sensor.

  • the sensors 12, 13 are connected to the central control unit 10 and the central control unit 10 is adapted to control the window 4 by applying an appropriate control potential to selected electrodes 8, thus causing the liquid crystal in the region of those selected electrodes to become opaque.
  • a safety device 14 may be provided in order to enable the window to perform satisfactorily in the event of a main power supply failure.
  • the device 14 may either contain batteries to maintain battery operation of the window or may comprise a mechanism to release a separate blind or similar mechanical screen in the event of a power failure.
  • the condition of the window may be controlled by actuating knobs or buttons on the central control unit 10, by operating the buttons on the remote control unit 11 or by voice actuation using the microphone.
  • the window may be made to be transparent or may be made to be opaque.
  • the window may have other mooes of operation.
  • the window may be caused to become progressively opaque automatically as a result of a comparison between internal ano external ambient light levels. When the level of ambient light within the room is high relative to the level of ambient light outside the room, the window may be made opaque to prevent people outside the room seeing into the room.
  • one or more areas of the window, or all of the window may be made to become opaque by speaking command words into the microphone on the control unit 10 or control unit 1 1. For example, using the words “DOWN”, “UP”, and “STOP”, the position control of a vertical blind may be imitated. A larger vocabulary of commands would allow for more sophisticated control of the window opacity.
  • control mechanism may incorporate a timer allowing selected daily periods for opacity of the window between sunset and sunrise.
  • one or more sections of the window, or all of the windows may be made to become opaque when a person is sensed within the room, for modesty purposes or when a person or vehicle is sensed outside tne window, for security reasons.
  • the window may again be caused to become increasingly opaque in response to a sensed temperature.
  • Touch sensitive means may be provided to sense the position of a f inger placed upon the interior of the window. For example, the ef fect ive capacitance of each of the electrodes 8 may be monitored, by tne microprocessor of the control unit 10, this capacitance altering when a finger is applied to the window adjacent the electrodes.
  • the area where the f inger is placed may become transparent for a predetermined period of time.
  • the window is opaque, for example at night-time, by merely rubbing a finger on the interior of the window, the area where the finger is rubbed will become transparent, thus providing a "peep-hole".
  • the "peephole” will only last for a predetermined period of time.
  • the position of the finger can be sensed to cause the window to become opaque only above the level of the finger, thus imitating a vertical blind.
  • Other modes could be incorporated to control the opacity in other directions relative to the position of the finger.
  • a sopnisticated control system may be provided enapling a specific area of the window to be made opaque, so that the opaque area of the window casts a shadow into the room.
  • the area of the window made to be opaque may be selected so that the shadow fails on a particular item of furniture that is not to be damaged by ultra-violet radiation from the sun.
  • the microprocessor may be programmed so that, as time passes, the position of the area of the window that is opaque moves in accordance with the movement of the sun, relative to the window, so that the item of furniture remains in shadow at all times.
  • the mask may only be active according to the sensed exterior brighthess so that during cloudy periods the mask would not be seen.
  • the micro-processor may utilise information relating to the time, date, and position and orientation of the window, together with information relating to the effective track of the sun, or the sensor 13 may include a light-sensitive imaging device, such as a charge coupled device which monitors the position of the sun relative to the window, and provides that information to the controller which can then calculate which area of the window should be made to be opaque to provide the desired effect.
  • a light-sensitive imaging device such as a charge coupled device which monitors the position of the sun relative to the window, and provides that information to the controller which can then calculate which area of the window should be made to be opaque to provide the desired effect.
  • Simpler control software could be used if three or more mask positions are defined which actually cause a shadow to be cast on the object at different times. The software could then move a mask so that it occupies the defined positions at the appropriate times. This would be appropriate for certain specific applications - for example, where sunlight is reflected from adjacent buildings.
  • the algorithm generated from the three or more positions of the mask, to control the movement of the mask may also be used to control the movement of other masks, so that they will provide shade for other objects. This algorithm is easily calculated as it is based on the and of a circle, and also the seasonal changes of the sun's position are easily calculated as they are based on a sine wave with the highest point being midsummer and the lowest point being midwinter.
  • Figures 2 and 3 illustrate a window 20 provided in a wall 21, the window being substantially south-facing, Contained within a room adjacent the window are two items A, B to be protected from the sun.
  • Two opaque areas 22, 23 are provided initially towards the right-hand side of the window 20, as shown in Figure 2, these areas being so located as to cast a shadow on the items A and B early in the morning, when the sun is towards the east.
  • Figure 4 illustrates the position of these opaque areas 22, 23 when viewed from the exterior of the window.
  • the described control arrangement will cause the opaque areas to move, as indicated by the dotted tracks 22', 23' until at the end of the day the opaque areas occupy the positions 22" and 23" as illustrated in Figures 2, 3 and 4.
  • a software flow chart as illustrated in Figure 5 may be followed, the effect of the various procedural steps being illustrated in Figure 6.
  • a joy-stick is utilised. Initially the mask control sequence is initiated and a button is pressed to select an object identification letter which appears on an appropriate display screen. A double click of a button starts mask positioning. A flashing mask spot or "cursor" will appear at the centre of the window. By moving the joy-stick the flashing spot is located at a first position of the mask outline, as illustrated at the first stage of Figure 6. The button may be pressed to define this position.
  • the Joy-stick may then be moved to re-locate the cursor at the corners of the desired mask area, the button being pressed at each corner area.
  • the outline of the mask is displayed on the window as an opaque line, and when the line forms the complete perimeter of a mask, a double depression of a control button causes the entire mask area to become opaque.
  • the erasure technique involves the re-commencement of the mask control sequence and the selection of the appropriate identification letter followed by a double depression of a button to start mask positioning. If the button is then held down, erasure of the mask may be effected.
  • the hand-operated control unit 11 may incorporate a light sensor.
  • the hand-operated unit 11 may then be located on the item of furniture or adjacent the item of furniture that is to be protected from direct sunlight, and initially the control unit 10 may be manually operated to set up an area of shade of a predetermined size surrounding the control unit 11.
  • the micro-processor will be adapted then to maintain the control unit 11 in shade for the great proportion of the time.
  • the control unit 11 would cause the pixels of the window to be "scanned" in order to determine precise position of the sun relative to the window and the unit 11. Appropriate calculations could then be carried out to ensure that the item of furniture on which the unit 11 is resting is in shade.
  • window arrangement has been described above with reference to an embodiment in which a liquid crystal arrangement is utilised to make the window opaque, it is to be appreciated that other expedients may be adopted, such as a mechanical blind, shutters or fabric mask or the like suspended within or adjacent the window.
