Abstract: The disclosure is directed to a system and methods for waking-up a wireless receiver on a wireless network. The method includes the steps of: listening, by the wireless receiver, for signals in a predetermined frequency band periodically and decoding a wake-up key; validating the wake-up key by correlating the wake-up key with values stored in a memory using a first processing device; if the wake-up key is validated, decoding at least one PHY Protocol Data Unit (PPDU) and checking the value of one or more bits of the PPDU to validate the decoded PPDU as a wake-up PPDU; if the wake-up packet is validated, decoding a wake-up address and comparing the wake-up address to the station (STA) wake-up address; if the decoded wake-up address matches the STA wake-up address, powering-up a second processing device and confirming wake-up by exchanging an encrypted frame with Access Point (AP).

Abstract: Methods and systems for connecting short term rental with distributed infrastructure are provided. According to one example, a server maintains access to a plurality of property data contracts on a decentralized blockchain ledger, each property data contract associated with a real property in a locale and a cancellation policy data contract. The server receives a booking data operation including a cryptocurrency transaction and a cryptocurrency address and verifies the booking data operation relative to the cancellation policy contract. Responsive to the verifying, the server approves the booking data operation, processes the cryptocurrency transaction, and updates the decentralized blockchain ledger. After the booking data operation has been approved, the server runs a token data operation to provide a token to the cryptocurrency address associated with the user electronic device.

Abstract: A mixture for enhancing eye lubrication comprises a plurality of microspheres having diameters ranging from about 5-40 microns combined with an aqueous component comprising water. The microspheres can be coated with oil. When the mixture is applied to the surface of a user's eyes, the microparticles will enhance lubrication during blinking and partially lift eyelids so that other components of the mixture can be better distributed beneath the eyelids. An oil can be added to the mixture. Preferably the oil is configured so that, when the mixture is agitated, it forms a temporary, thermodynamically unstable emulsion from which the oil quickly disassociates when the mixture is applied to the eye. The oil thus is quickly available to enhance lubrication performance.
