  • Publication number: 20240053650
    Abstract: An electro-optic assembly includes a first substrate that has a first surface and a second surface that is opposite the first surface. A second substrate has a third surface and a fourth surface that is opposite the third surface. The first and second substrates are disposed in a parallel and spaced apart relationship so as to define a cavity therebetween. The second and third surfaces face each other. A seal extends between the first and second substrates. An electro-optic medium is located in the cavity and is retained by the seal. A port is at least partially defined by a port reduction member that is located between the first substrate and the second substrate.

  • Patent number: 11130195
    Abstract: A laser ablation process can be configured to reduce the appearance of or eliminate a potentially objectionable diffraction effect that can occur when a workpiece or product that has been subjected to the ablation process interacts with light. The diffraction effect can be reduced by introducing irregularity into the arrangement of overlapping laser spots during the process. Other process parameters may be modified to reduce the diffraction effect, such as laser scan speed, laser pulse frequency, the position of the focal plane of the laser, the configuration of raster lines, or the energy profile of the laser beam, for example. The process modifications and configurations are particularly useful with products including an ablated surface that is intended to reflect light or to allow light to pass therethrough as part of its function.

  • Patent number: 11126056
    Abstract: A method for removing a material from a surface of a substrate includes impinging a laser beam on the material during a first sweep to remove the material from the surface along a first line and impinging the laser beam on the material during a second sweep to remove the material from the surface along a second line adjacent to the first line. The first line includes first artifacts that form a first portion of an array of artifacts on the surface. The second line includes second artifacts that form a second portion of the array of artifacts on the surface. A first laser pulse of the laser beam corresponding with the second sweep is synchronized with a start of the second sweep when transitioning between the first line and the second line such that the start of the second sweep coincides with the first laser pulse.

  • Patent number: 10955719
    Abstract: A transparent photovoltaic (TPV) integrated directly into the structure of an electrochromic (EC) device is beneficial in that it can eliminate at least one substrate and provide more uniform coloring. Integration of a transparent photovoltaic with an electrochromic device may also reduce or eliminate the need for an electrical bus on a substrate. In some embodiments, positioning the TPV internally with the EC cell may eliminate the need for additional substrate layers or a conductive layer on one side of the TPV cell. Integrating a PV cell into the EC device can additionally reduce the need for external wiring and an external power supply. Alternatively, the TPV can assist in charging a battery where the battery can be used to power the EC device when there is no sunlight available.

  • Patent number: 10538202
    Abstract: A method of making a mirror reflective element suitable for use in a vehicular exterior rearview mirror assembly includes providing front and rear substrates, and disposing an electrically conductive layer and a metallic reflector at respective surfaces thereof. With the substrates joined and with an electrochromic medium disposed in an interpane cavity, light that reflects off of the mirror reflector and passes through the electrochromic medium and the front substrate is non-spectrally selective when no voltage is applied to the electrochromic medium. At least a portion of the mirror reflector extends under the perimeter seal and towards a perimeter edge of the rear substrate. A display is disposed to the rear of the rear substrate of the mirror reflective element at a light-transmitting window. The display is operable responsive to a blind spot detector of a vehicle equipped with an exterior rearview mirror assembly that incorporates the mirror reflective element.

  • Publication number: 20190344389
    Abstract: A laser system includes a laser configured to provide a laser beam and a laser delivery assembly including a waveplate. The laser delivery assembly is positioned to receive the laser beam from the laser and direct the laser beam toward a substrate to facilitate forming a separation line within the substrate along a process path. An instantaneous direction of the process path relative to a direction of a crystalline plane of the substrate defines a process path angle. The laser delivery assembly is configured to selectively rotate at least one of the waveplate or the substrate to control a polarization angle of the laser beam based on (i) an instantaneous direction of polarization of the laser beam and (ii) the process path angle.

  • Patent number: 10471546
    Abstract: A laser system is configured to produce a distribution of self-focus damage volumes through the thickness of a substrate. A laser of the laser system produces a laser beam, and an optical assembly receives the laser beam and emits a conditioned laser beam having a geometric focal region. Placing the substrate in the path of the conditioned beam shifts the focal region to an effective focal region. The optical assembly and/or optical elements thereof can be configured such that the distribution of self-focus damage volumes is uniform over the thickness of the substrate by accounting for the non-linear effects of the substrate on the light that propagates through the substrate.
