Abstract: A method of using a first device to locate a second device is disclosed. The first device, while in a first mode, transmits a first signal and receives a second signal comprising a reflection of the first signal by the second device. The first device determines, based on the received second signal, a position of the second device relative to the first device. The first device transitions to a second mode, and while in the second mode, receives a third signal from the second device. The first device determines, based on the third signal, an orientation of the second device relative to the first device. The first device comprises one or more receiving antennas, and the second device comprises one or more transmitting antennas. The third signal corresponds to a transmitting antenna of the second device.

Abstract: A method of operating an optical system includes identifying a set of angle dependent transmittance levels for light passing through pixels of a segmented dimmer exhibiting viewing angle transmittance variations for application of a same voltage to all pixels of the segmented dimmer. The method also includes determining a set of voltages to apply to pixels of the segmented dimmer. Determining the set of voltages includes using the set of angle dependent transmittance levels. The method includes applying the set of voltages to the pixels of the segmented dimmer to achieve light transmittance through the segmented dimmer corresponding to the set of angle dependent transmittance levels.
