Abstract: A Brayton cycle engine including a longitudinal wall extended along a lengthwise direction. The longitudinal wall defines a gas flowpath of the engine. An inner wall assembly is extended from the longitudinal wall into the gas flowpath. The inner wall assembly defines a detonation combustion region in the gas flowpath upstream of the inner wall assembly.

Abstract: A Brayton cycle engine and method for operation. The engine includes an inner wall assembly and an upstream wall assembly each extended from a longitudinal wall into a gas flowpath. An actuator adjusts a depth of the detonation combustion region into the gas flowpath between the inner wall assembly and the upstream wall assembly. The engine flows an oxidizer through the gas flowpath and the inner wall captures a portion of the oxidizer. The engine further adjusts the captured flow of oxidizer via the upstream wall and flows a first flow of fuel to the captured flow of oxidizer to produce rotating detonation gases. The engine flows the detonation gases downstream and to mix with the flow of oxidizer, and flows and burns a second flow of fuel to the detonation gases/oxidizer mixture to produce thrust.

Abstract: The present disclosure describes a computer-implemented platform for managing electronic instruments and electronic endorser verification information in order to validate endorser identity. A generated link and a verification information request are sent in one or more messages targeted a phone number of a computing device associated with a target party. The verification information request includes a request for imagery of the target party captured by the computing device. An endorsed electronic instrument and electronic verification information is received from the computing device, including received imagery data and a time stamp indicating when the received imagery data was captured. The received imagery data is validated at least according to whether the time stamp is sufficiently recent, and whether the received imagery data sufficiently matches expected imagery data of the requesting party based on performing a facial recognition on the received imagery data and the expected imagery data.

Abstract: A system for dynamic pricing of secondhand goods comprising: a tag corresponding to an item, a database for hosting information regarding a plurality of items, a software capable of comparing items within the system and identifying a sale price, a location for placing the item for sale; placing an item for sale and dynamically raising or lowering the price of the item for sale as the information in the database is modified.

Abstract: The present disclosure describes a computer-implemented platform for managing electronic endorsable instruments and electronic endorser verification information in order to validate endorser identity. A computer system receives an endorsable electronic instrument and a mobile phone number associated with a targeted potential endorser. The endorsable electronic instrument and a verification information request are sent to the mobile phone number by sending a link to an endorsement application via a message to the mobile phone number. The endorsed electronic instrument and corresponding verification information are received and are associated to validate the endorsed instrument.
