Abstract: A wearable display system includes a light projection system having one or more emissive microdisplays, e.g., micro-LED displays. The light projection system projects time-multiplexed left-eye and right-eye images, which pass through an optical router having a polarizer and a switchable polarization rotator. The optical router is synchronized with the generation of images by the light projection system to impart a first polarization to left-eye images and a second different polarization to right-eye images. Light of the first polarization is incoupled into an eyepiece having one or more waveguides for outputting light to one of the left and right eyes, while light of the second polarization may be incoupled into another eyepiece having one or more waveguides for outputting light to the other of the left and right eyes. Each eyepiece may output incoupled light with variable amounts of wavefront divergence, to elicit different accommodation responses from the user's eyes.

Abstract: Disclosed is a system, a method and computer-readable medium for implementing a smart contract on a blockchain. The method includes creating, via a processor, a smart contract documenting a contractual relationship of at least two parties based on an exchange of an asset, monitoring an execution of the smart contract and a current value of the asset to yield a status, and managing the smart contract based on the status. The smart contract can be exited and unused gas returned based on an event occurring or a quorum parameter being met.

Abstract: A method for tracking data transferred to mobile devices. The method includes receiving a first user request for first content data provided by a content provider, and forwarding the user request to a provider server. The method includes receiving the first content data associated with the first user request, and forwarding the first content data associated with the first user request to the first user mobile device. The method includes determining that the first content data is part of a predetermined set of whitelisted content data. The method includes determining a first amount of data transferred to the first user mobile device when the first content data is forwarded to the first user mobile device. The method includes, based on the determination that the first content data is part of the predetermined set of whitelisted content data, logging the first amount of data.

Abstract: A method for conducting a transaction between two parties includes receiving, from a first mobile device, a first identifier identifying a first party to a transaction for a product. The method includes receiving, from the first mobile device, a transaction request associated with the first identifier including a product identifier, a price indicator, and a second identifier associated with a second mobile device and identifies a second party to the transaction. The first and second mobile devices operate via different mobile network operators. The method includes transmitting, to the second mobile device, a request for confirmation of the transaction including the product identifier and the price indicator. In response, the method includes determining whether an account associated with the first identifier includes sufficient funds, and transferring an amount from the account associated with the first identifier to an account associated with the second identifier.
