    Abstract: A controller or control method may be designed or configured to operate without information about the current temperature of the device and/or the device's environment. Further, in some cases, the controller or control method is designed or configured to control transition of an optical device to an intermediated state between two end states. For example, the controller may be configured to control a transition to a state of transmissivity that is intermediate between two end states of transmissivity. In such case, the device has three or more stable states of transmissivity.

  • Patent number: 8716644
    Abstract: The invention provides a glare reduction apparatus disposed in an object illuminated by a light source. The glare reduction device includes an electro-optical device covering a surface of the object. A light sensing device is disposed on a first fixed point of the object. A controller is electrically coupled to the electro-optical device and the light sensing device, wherein the controller calculates a corresponding light sensing position of the electro-optical device according to a light sensing position of the light sensing device which directly receives light from the light source, to reduce the light transmittivity of the corresponding light sensing position of the electro-optical device to generate a light shielding region. The light shielding region attenuates the light from the light source to a second fixed point of the object.

  • Patent number: 7903314
    Abstract: In an electrochromic mirror, an insulating film is disposed between a conductive reflective film and an electrolytic solution and the conductive reflective film and the electrolytic solution are electrically insulated from each other except inside of insulating film side small holes. Accordingly, in a portion where the insulating film side small holes are not formed, the conductive reflective film does not come into contact with the electrolytic solution, as the result, a ferrocene ion is not reduction-reacted. Thereby, a current is very effectively suppressed from steadily flowing between the conductive film and the conductive reflective film due to repetition of a redox reaction of ferrocene, resulting in very effectively suppressing a voltage from dropping due to the current.

A stowable laser eye protection system provides protection that can be manually or automatically extended and retracted. For example, by installing flexible laser protective films on rollers at each window of an aircraft cockpit, the protection can be put in place during taxi before take-off and stowed when the aircraft is a safe distance away from a potential threat area such as after reaching a particular altitude. A similar activity could be used for approach and landing, where the protection is extracted when the aircraft approaches a threat condition or critical phase of flight and retracted after landing.

  • Patent number: 6574049
    Abstract: Optical interleavers and de-interleavers that can be used to combine and separate optical signals are described. These devices are based on Mach-Zehnder interferometers having one or two Gires-Toumois mirrors. The optical designs disclosed herein include several key improvements over prior arts. These improvements of interleavers enabled lower cross talk and more accurate channel center frequencies. The new designs also improve on the stability of the devices and substantially reduce the manufacturing costs. With the usage of multi-fiber collimators, a pair of interleaver and de-interleaver is fabricated using the same optical block thereby further reducing the manufacturing costs.

  • Publication number: 20020181112
    Abstract: An automatically dimming mirror includes a dimming element having variable reflectivity, the degree of reflectivity based on a control signal. An ambient light sensor is positioned to receive light from a region generally in front of the vehicle. The ambient light sensor outputs a discrete ambient light signal based on the amount of light incident on the ambient light sensor over an integration period. A glare sensor is positioned to view the scene generally behind the vehicle operator. The glare sensor outputs a discrete glare signal based on the amount of light incident on the glare sensor over an integration period. A dimming logic determines an ambient light level based on the ambient light signal. The glare integration period is determined based on the ambient light level. The glare signal resulting from the glare integration period determines a mirror glare level used to set the dimming element control signal.

  • Publication number: 20020159155
    Abstract: Protective eyewear for blocking laser light from entering the eyes of the wearer. The eyewear having a light absorbing filter and an adjacent light-reflecting filter such that laser light will first be reflected by the reflecting layer and then absorbed by the absorbing layer. If the light-reflecting filter is damaged or scratched the light not reflected would be absorbed by the light-absorbing filter. Similarly if the angle of incidence is such that the light-reflecting filter does not reflect the incident light the light-absorbing filter will absorb the light. The light-reflecting filter reflects a majority of the incident light on the protective eyewear and thus protects the light-absorbing filter from reaching its damage threshold. The combination of light absorbing and light reflecting filters provides better protection against light penetration of a specified wavelength than either type of filter working along.

The shapes of the grooves (16) or other surfaces features are such that they touch in some places (20, 22, 23) and are spaced from one another in others (18, 19) to form voids (24) within the composite body (11) so formed. These cavities (24) assist in determining total internal reflection of incident light at certain angles. Composites bodies formed from two face-to face optical components may be used as daylighting screens both to direct light towards an object such as the interior of a building (through an opening) or to screen light from it by diverting it away therefrom.
