Abstract: A computing system for remotely activating a transaction device including at least one memory having instructions stored thereon that, when executed by the at least one processor, cause the at least one processor to receive, from a mobile device, a transaction device identifier, receive, from the transaction device, an authorization request associated with a payment account for a transaction at the transaction device, receive location information from the mobile device and location information from the transaction device in response to receiving the authorization request, compare the location information to determine whether the mobile device is in proximity to the transaction device, and upon determining that the mobile device is in proximity to the transaction device, determine an authorization status of the authorization request, and transmit a signal to activate the transaction device to complete the transaction, wherein the signal is transmitted based on the transaction device identifier.

Abstract: A method of remotely activating a transaction device includes receiving, at a computing system, a mobile device identifier from a mobile application executed on a mobile device. A selection of the transaction device is received from the application. The selection includes an identifier of the transaction device. A selection of a transaction amount related to purchase of a product is received from the application. An authorization request for a payment account associated with the mobile device is communicated to an issuer of the payment account. The authorization request is for a transaction of at least the transaction amount. An authorization approval for the transaction is received from the issuer and a signal to activate the transaction device to dispense the product is sent based on the identifier. The transaction device is deactivated upon dispensing the transaction amount and a receipt of the transaction is provided to the mobile device.

Abstract: The invention provides a cryogenic liquid pump system, having a first end with at least an insulating lid and motor; a second end, wherein the second end is a pump, said pump comprising an impeller; and a gas release plate upstream of the impeller; and a shaft disposed between the first end and the second end, wherein the motor imparts mechanical energy to the pump through the shaft. Also provided is a method for preventing cavitation of a cryogenic liquid in a cryogenic pump, the method having the steps of constantly maintaining pressure on the liquid in the pump and evacuating gas bubbles that form within the pump.

Abstract: In a general aspect, control of a quantum superconducting circuit is analyzed. In some implementation, a parameter set for a control signal for a superconducting quantum circuit is received. The parameters set can include initial voltage amplitudes for respective time segments of the control signal. A first subset of time segments is selected for improving a quality measure of a quantum logic operation produced by delivery of the control signal in the superconducting quantum circuit. New voltage amplitudes are calculated for one or more segments in the first subset, such that the new voltage amplitudes improve the quality measure. The parameter set is updated to include the new voltage amplitudes for the first subset while preserving the initial voltage amplitudes for a second subset of the time segments.

Abstract: The invention is directed to a safety globe valve having a housing and a stem. The stem is disposed within a hollow interior of the housing and disposed in a safety orientation. The safety orientation includes at least first stem member in spaced apart relation to at least second stem member. The stem can be also disposed in an operative orientation. The operative orientation includes at least first stem member temporarily connected to at least second stem member. At least first member of the stem is structured to retract in opposite direction of at least second stem member, upon disposing the stem in the safety orientation. At least first stem member is structured to advance in direction of at least second stem member, while disposing the stem in the operative orientation. The invention is also directed to a method to prevent accidental valve openings.
