Abstract: System, methods and products for receiving an indication of a booking event completed by a user utilizing an application executed on a computing machine, the booking event being memorialized by way of storing a booking record in a booking database, the booking event being associated with a user's balance, the user's balance being represented by a number of points divisible into a first points portion and a second points portion. One or more electronic tokens are generated having a first value equal to a value of the first points portion, in response to a first threshold being met. The one or more electronic tokens are stored in an electronic ledger associated with the user. The user may be authorized to utilize the one or more electronic tokens on an electronic exchange platform to obtain one or more items or services. The second points portion are as credit on the user's balance. In one embodiment, the user is not authorized to use the credit to obtain items or services of value.

Abstract: Methods and systems for acquiring a freehand or cursive signature on a secondary device with a touch receiving surface for use on a primary device without a touch receiving surface are provided. The primary device sends a message to the secondary device requesting a signature. The user responds by signing her name, using a finger or stylus, on a touch receiving surface. As the user signs her name, the signature is displayed on the secondary device and transmitted to the primary device. The signature may then be stored, displayed, analyzed, or validated by the primary device.

Abstract: An in-space spacecraft servicing system (10) includes a servicing spacecraft (22) and a propellant module (24). The servicing spacecraft includes a client servicing system (136), as well as navigation avionics (108) for independent flight operation and a servicing propellant tank (170). The propellant module moves the servicing module from an upper stage drop off location and releases it in proximity to a client spacecraft (16) for a servicing mission. It has a propellant tank (172) with capacity for multiple missions and is used to refill the servicing spacecraft's propellant tanks between missions. Either or both the servicing spacecraft and the propellant module may have navigation avionics. The servicing spacecraft also has a universal docking adaptor (70) for different client spacecraft, and can convert a client spacecraft from non-cooperative to cooperative.

Abstract: The electromechanical regulator for passenger oxygen is a hybrid oxygen regulator that provides for electronic or mechanical regulation of oxygen flow. The electronic portion of the regulator consists of an inlet solenoid valve, an outlet solenoid valve, a cabin pressure transducer, a regulated output transducer and a PID based controller, and the solenoid valves are normally biased so that in the event of an electronic system failure or a power supply failure the system will automatically revert to mechanical operation.

Abstract: The riser line shutoff valve where oxygen flows into the valve from the inlet and through an orifice in the piston. This orifice creates differential pressure between the upstream and downstream side of the piston. When the differential pressure across the piston exceeds the spring load and friction between the piston and the valve body, the piston moves to the left and seats on the brass probe in the conical area of the piston, preventing the flow of oxygen. The valve will not open until the upstream pressure is removed. The base of the brass probe has holes, allowing oxygen to flow out of the outlet port when the valve is open. The probe is threaded into the probe base allowing for valve adjustment for proper operation. The spring simultaneously serves the functions of retaining the probe base and providing a piston load to keep the piston open until the critical flow rate is reached.
