Abstract: An optical structure is described for correcting display viewing angle color shift. The optical structure includes a microlens array layer having a first surface and a second surface forming an array of microlenses. A portion of the microlens array layer is formed of a color loading material having a density that results in a desired difference between a color shift at a non-zero viewing angle and a color shift at a zero viewing angle.

Abstract: An automated checkout call-forward (ECF) system comprises a queuing area for channelling customers, which leads to one or more checkouts. Each checkout comprises a service area and each checkout can be in either an available condition to accept a new customer, or in an unavailable condition. An indicator is capable of directing a customer to an available checkout. A sensor system is capable of detecting and providing output parameters indicative of the presence of one or more customers in the queuing area and the presence of one or more customers in the service area of each checkout. The automated ECF system is configured to identify any available checkouts based on interpreting the sensor output parameters and to instruct the indicator based on the identified available checkouts.

Abstract: An optical external modulator includes an optical waveguide having a first interferometer section and a second interferometer section formed on an electro-optic substrate. An electrode structure disposed on the substrate transmits an RF drive signal that is applied to the first and second interferometer sections in series. A reflector optically coupled to the substrate redirects light away from the first interferometer section to the second interferometer section and provides an optical fold region that introduces an optical time delay between the first and second interferometer sections. The optical time delay is used for at least partially compensating for a velocity mismatch between the light and the RF drive signal.
