Abstract: A multilayer polymer thin film includes an anti-reflective coating directly overlying a reflective polarizer stack. The reflective polarizer stack includes alternating first and second polymer layers, where the first layers include an isotropic polymer thin film and the second layers include an anisotropic polymer thin film. The anti-reflective coating (ARC) includes alternating third and fourth layers, where the third layers include an isotropic polymer thin film or an anisotropic polymer thin film and the fourth layers include an isotropic polymer thin film. The multilayer polymer thin film may be formed by co-extrusion where the reflective polarizer stack and the anti-reflective coating are formed simultaneously.

Abstract: The disclosed apparatus may include a holding affordance that is configured to hold an optical element, a beam emitter, and a beam sensor, where the holding affordance is positioned, along a first dimension, between the beam emitter and the beam sensor; a first linear stage that supports the beam emitter and that, when actuated, moves the beam emitter along a second dimension; a first rotational stage that supports the beam emitter and that, when actuated, rotates the beam emitter in a staging plane defined by the first dimension and the second dimension; a second linear stage that supports the beam sensor and that, when actuated, moves the beam sensor along the second dimension; and a second rotational stage that supports the beam sensor and that, when actuated, rotates the beam sensor in the staging plane. Various other systems and methods are also disclosed.

Abstract: A computer-implemented method for optical element fabrication with optical scanner feedback includes initiating the optical scanner to obtain an optical measurement of an optical layer of a multi-layer film. A rotational orientation for an optical element that is to be cut from the multi-layer film is then determined based on the optical measurement. The method also includes initiating a cutting instrument to cut the optical element from the multi-layer film at the rotational orientation.

Abstract: Deleting items based on user interaction is disclosed, including: determining a set of items to delete from a device; generating a representation associated with the set of items; presenting the representation associated with the set of items at the device; detecting a user input operation associated with modifying the presentation of the representation associated with the set of items at the device; and deleting at least a portion of the set of items based at least in part on the modified presentation of the representation associated with the set of items.

Abstract: A method and an apparatus of payment processing, a transaction method and a mobile device are disclosed. The payment processing method includes collecting an audio signal; obtaining a graphic code, wherein the graphic code is generated based on a predetermined account and a number recognized from the audio signal, the number being used for indicating an amount to be paid and the predetermined account being an account that is to have a payment activity; and displaying the graphic code, wherein the graphic code is used for triggering the payment activity with the predetermined account to complete a payment of the amount corresponding to the number upon being scanned. The present disclosure solves the technical problems of a relatively low efficiency of offline transaction processes caused by the need of manual entry of a payment account for each offline payment.
