Abstract: Dynamic windows with adjustable tint give users greater control over flow of light and heat. Reversible metal electrodeposition dynamic windows include (i) a transparent or translucent conductive electrode; (ii) an electrolyte solution in contact with the electrode, the electrolyte solution comprising metal cations that are reversibly electrodeposited onto the transparent electrode upon application of a cathodic potential; and (iii) a counter electrode. The electrolyte solution advantageously includes a small amount of an additive (e.g., an inhibitor, an accelerator, a leveler, or an organic or inorganic molecule that similarly serves to enhance the surface morphology of the metal cations during reversible metal electrodeposition onto the transparent electrode). Such enhancement of surface morphology during the reversible electrodeposition of the metal tinting layer over the electrode enhances one or more of color neutrality, transmittance characteristics of visible wavelengths (e.g., ability to achieve a near 0% transmission privacy state), infrared reflectance, or switching speed.

Abstract: A method of controlling a non-light emitting, variable transmission device is disclosed. The method can include receiving state information from at least one wearable device, prioritizing the received state information, sending signals from a remote management system to a first controller in response to the received prioritized state information, and changing a first transmission state of a non-light-emitting, variable transmission device to a second transmission state for the non-light-emitting, variable transmission device in response to the signals received from the first controller.

Abstract: Electrochromic "smart" windows allow control of solar and heat flux through the window without sacrificing the view. Despite such appeal, traditional technologies lack the inability to simultaneously achieve fast switching with color neutral tinting and a wide optical dynamic range at low cost. Reversible metal electrodeposition (RME) addresses the drawbacks of existing metal-oxide electrochromic technologies. Several possible RME electrolytes at various pHs with different supporting anions were studied (NO3-, SO42-, ClO4, Cl‑, Br-). Acidic perchlorate electrolytes work particularly well, permitting fully reversible metal electrodeposition without harming the substrate or introducing irreversible side reactions. The perchlorate electrolyte shows promising long-term durability in terms of both cycle life and shelf-life, demonstrating 10,000 stable cycles with no evidence of electrode etching. In addition, the use of this perchlorate electrolyte widens the deposition voltage window, enabling construction of relatively large area dynamic windows that tint relatively uniformly with fast, color-neutral switching at low cost.

Abstract: A system and method for color correction in an electrochromic device includes applying a stepped voltage profile to the electrochromic device in a high-transmission state to achieve a desired low-transmission state. Each step of the stepped voltage profile is at a step difference of about 0.01 volts to about 0.5 volts from an adjacent step with each successive step being at a varying voltage level and each of the steps is held for a time period from about 0.1 seconds to about 10 seconds. At the desired low-transmission state, the system and method include applying a reverse bias voltage from about 0.01 volts to about 0.5 volts for about 0.01 seconds to about 10 seconds to color correct the low-transmission state.

Abstract: An eyewear device including a frame (110) an optical sensor (129) to measure environmental light, a lens (120) including a transmission control region (124) that is switchable between first and second configurations, operable to reflect and/or absorb light within the visible spectrum to reduce and/or enhance non-visual responses to light, and operable to permit light within the affected wavelength range to pass therethrough in the second configuration. Electrodes (121) electrically coupled to the transmission control region (124) may enable an electric current to flow through the transmission control region (124). A control system (140) electrically coupled to the electrodes (121) and the optical sensor (129) may control the operation of the eyewear device.

Abstract: Systems and methods are disclosed for using a color changing surface to display a status of a storage device. In certain embodiments, a storage includes a display-less enclosure, non-volatile memory, memory configured to store firmware, and control circuitry. The control circuitry can be configured to determine an available space in the non-volatile memory, determine a first color corresponding to the available space based on a mapping of ranges of available space to corresponding colors, apply a voltage to the electrochromic material to change the color changing surface to the first color, and cease application of the voltage to the electrochromic material, wherein the color changing surface retains the first color after cessation of the voltage.
