Abstract: A switchable one-way mirror device dividing first and second spaces includes a switchable electro-optic layer facing the second space and configured to be electronically switchable between a transmissive state and one or more opaque states, and a partial reflector incorporated within or adjacent the switchable electro-optic layer and facing the first space and configured to partially reflect light. The switchable one-way mirror partially transmits a first light going from the first space to the second space, and a second light going from the second space to the first space. When the switchable electro-optic layer is in an opaque state, transmission of light through the device is reduced thereby changing the ratio between the transmission of the second light to the first space and the reflection of the first light by the partial reflector resulting in reduced visibility of the second space by a viewer in the first space.

Abstract: An electronically controllable eyewear device having a cell filled with a liquid crystal material that can be electronically operated in an auto or a manual mode. The device contains a photosensor for generating a light input signal to trigger an automatic application of voltage to the cell when the device is in an auto mode, one or more switches capable of being actuated in a series of actuation sequences each to select a distinct function, and a control circuit responsive to each actuation sequence and light input signal to operate the cell in a corresponding one of a plurality of functions, including: (i) a first sequence for affecting an ON/OFF function, (ii) a second sequence for affecting a system change from the manual mode to the auto mode, and (iii) a third sequence for changing the threshold value for triggering the automatic application of voltage.
