Dimmable mirror assembly and method thereof
First Claim

1. A manual dimmable mirror assembly comprising:
- a mirror element comprising;
a first substantially transparent substrate comprising;
a first surface; and
a second surface, said second surface having a transparent electrically conductive coating;
a second substantially transparent substrate substantially parallel with said first substantially transparent substrate, said second substantially transparent substrate comprising;
a third surface comprising at least one coating such that said third surface is at least partially reflective; and
a fourth surface;
wherein said first substantially transparent substrate and said second substantially transparent substrate define a cavity;
an electro-optic medium in said cavity;
a input device; and
a controller in communication with said input device, said controller configured to control electrical power supplied to said mirror element, such that said mirror element transitions from a substantially clear state to a substantially dark state at least partially based upon said communication from said input device;
wherein said controller is further configured to determine if said mirror element was in said substantially dark state prior to the vehicle being turned off, and when the vehicle is turned on, if an off time is less than a threshold, then said controller controls electrical power to said mirror element so that said mirror element is in said substantially dark state.

Abstract
A manual dimmable mirror assembly includes a mirror element having a first substantially transparent substrate and a second substantially transparent substrate. The first and second substantially transparent substrates are substantially parallel and define a cavity that contains an electro-optic medium. The mirror assembly also includes an input device and a controller in communication with the input device. The controller configured to control electrical power supplied to the mirror element, such that the mirror element transitions from a substantially clear state to a substantially dark state at least partially based upon the communication from the input device.

11. A manual dimmable mirror assembly comprising:
-
a mirror element comprising; a first substantially transparent substrate comprising; a first surface; and a second surface, said second surface having a transparent electrically conductive coating; a second substantially transparent substrate substantially parallel with said first substantially transparent substrate, said second substantially transparent substrate comprising; a third surface comprising at least one coating such that said third surface is at least partially reflective; and a fourth surface; wherein said first substantially transparent substrate and said second substantially transparent substrate define a cavity; an electro-optic medium in said cavity; a input device; and a controller in communication with said input device, said controller configured to control electrical power supplied to said mirror element, such that said mirror element transitions from a substantially clear state to a substantially dark state at least partially based upon said communication from said input device; wherein said controller is further configured to receive time data from a vehicle bus, and if received time data is related to night time driving hours, then control electrical power supplied to said mirror element so said mirror element in said substantially dark state. - View Dependent Claims (12, 13, 14, 15)

16. A method of controlling a manual dimmable mirror assembly in a vehicle, said method comprising the steps of:
-
activating an electro-optic dimmable mirror to be in a substantially dark state; determining, when the vehicle has been turned off and turned on again after said activation, and if so, then determining if at least one of two vehicle timing conditions is satisfied, the two vehicle timing conditions being (i) if the vehicle was off for less than a threshold time period, and (ii) if received time data is related to night time driving hours; activating said dimmable mirror assembly to be in said substantially dark state if either of the two vehicle timing conditions is satisfied; and activating said dimmable mirror assembly to be in a substantially clear state if neither of the two vehicle timing conditions is satisfied. - View Dependent Claims (17, 18)
