  • Patent number: 9188828
    Abstract: A control circuit and a method for maintaining light transmittance of an electrochromic device are revealed. An input power source is turned off once a current input into an electrochromic device is decreased to a preset value. Then a voltage between two electrodes of the electrochromic device is detected. When the voltage between two electrodes of the electrochromic device is dropped to a preset value, the input power source is restored. According to the above steps, the coloration of the electrochromic device is maintained within a preset range. Thus light transmittance of the electrochromic device is kept at a certain range.

    Abstract: A transmittance control method of electrochromic element, mainly comprising the following step: firstly, a total current flux input required is obtained by adding current value of each second together by the relationship between different current value and different rate of change of the electrochromic element obtained in terms of the same transmittance and different input voltages, then the total current flux for fixed transmittance is input into the electrochromic element in usage so as to achieve a transmittance of fixed value. In this manner, the electrochromic element can quickly achieve a transmittance of fixed value in precise manner, without repeated adjustment. Further, there is not such case happened as to influence the accuracy of its transmittance even after aging time lapse.

  • Patent number: 9081247
    Abstract: Controllers and control methods apply a drive voltage to bus bars of a thin film optically switchable device. The applied drive voltage is provided at a level that drives a transition over the entire surface of the optically switchable device but does not damage or degrade the device. This applied voltage produces an effective voltage at all locations on the face of the device that is within a bracketed range. The upper bound of this range is associated with a voltage safely below the level at which the device may experience damage or degradation impacting its performance in the short term or the long term. At the lower boundary of this range is an effective voltage at which the transition between optical states of the device occurs relatively rapidly. The level of voltage applied between the bus bars is significantly greater than the maximum value of the effective voltage within the bracketed range.

A perimeter portion of the front substrate extends beyond a corresponding perimeter portion of the rear substrate to establish a user input region that is outboard of the electro-optic active region. A user input, such as a touch sensor, is disposed at the user input region, and the user input is not in electrical contact with the transparent electrically conductive coating at the rear surface of the front substrate. The user input is operable to detect the presence or touch of a person's finger at the user input region.

  • Patent number: 9013778
    Abstract: One object of the present invention is to provide an electrochromic device having improved insulating film structure to reduce electrical leakage. The improved structure includes a lower conductive layer, upper conductive layer, an electrochromic electrode layer, a counter electrode layer, and at least one ion-conductor layer sandwiched between the electrochromic electrode layer and the counter electrode layer. The lower conductive layer and the electrochromic electrode layer are scribed and the gap formed from the scribing is filled with the layers formed above the electrochromic electrode layer. In some aspects, the ion-conductor layer is also scribed with the lower conductor and electrochromic electrode layers and the gap formed from the scribing is filled with the layers formed above the ion-conductor layer. In further aspects, the insulating film may include one or more buffer layers formed above an ion-conductor layer, further separating the upper conductive layer from the lower conductive layer.

  • Patent number: 9011734
    Abstract: Ligand exchange of thermochromic, LETC, systems exhibiting a reversible change in absorbance of electromagnetic radiation as the temperature of the system is reversibly changed are described. The described LETC systems include one or more than one transition metal ion, which experiences thermally induced changes in the nature of the complexation or coordination around the transition metal ion(s) and, thereby, the system changes its ability to absorb electromagnetic radiation as the temperature changes.

  • Patent number: 9007674
    Abstract: Electrochromic devices and methods may employ the addition of a defect-mitigating insulating layer which prevents electronically conducting layers and/or electrochromically active layers from contacting layers of the opposite polarity and creating a short circuit in regions where defects form. In some embodiments, an encapsulating layer is provided to encapsulate particles and prevent them from ejecting from the device stack and risking a short circuit when subsequent layers are deposited. The insulating layer may have an electronic resistivity of between about 1 and 108 Ohm-cm. In some embodiments, the insulating layer contains one or more of the following metal oxides: aluminum oxide, zinc oxide, tin oxide, silicon aluminum oxide, cerium oxide, tungsten oxide, nickel tungsten oxide, and oxidized indium tin oxide. Carbides, nitrides, oxynitrides, and oxycarbides may also be used.

  • Patent number: 9001409
    Abstract: A cover for use in connection with a mirror of a vehicle is provided. The cover is provided with a lens having an electrically activatable material. The lens is positioned in front of the vehicle mirror. The electrically activatable material blocks visible light directed towards the vehicle mirror such that the electrically activatable material prevents the visible light from being reflected off of the vehicle mirror when the electrically activatable material is set to a light inhibiting state. A device that holds the lens is securable to the vehicle mirror. The electrically activatable material of the lens is configured to be switched to the light inhibiting state in response to user operation such that the lens prevents reflection of the visible light off of the vehicle mirror to reduce observability of the vehicle mirror.

    Abstract: An extended field of view exterior mirror element suitable for use in a driver-side exterior sideview mirror assembly includes a reflective single glass element having a substantially flat inboard reflective glass portion and a curved outboard reflective glass portion. The substantially flat inboard reflective glass portion has a radius of curvature greater than at least approximately 12,000 millimeters and provides a first primary field of view rearward of the vehicle that subtends an angle that is not greater than approximately 20 degrees with respect to the driver-side of the vehicle. The curved outboard reflective glass portion provides a second auxiliary field of view rearward of the vehicle that encompasses a blind spot of the substantially flat inboard reflective glass portion. The reflective single glass element includes a demarcation that generally demarcates the substantially flat inboard reflective glass portion from the curved outboard reflective glass portion.
