Abstract: An electronic business postal system collects, clears and delivers electronic business mail through a closed access, secure messaging system. A collection subsystem consists of access portals that are associated with secured system nodes. The access portals provide authenticated users access to the system to send and retrieve electronic business mail that includes postal system electronic delivery addresses, physical delivery addresses, or both. Secured message servers that are associated with the respective access portals process the electronic business mail into uniquely identified messages for delivery over the system nodes and also process received messages to provide the corresponding electronic business mail to the intended recipients through associated access portals. A delivery subsystem directs the messages through the system nodes associated with the senders' access portals to the system nodes associated with the recipients' access portals.

Abstract: The present invention is directed to an intraluminal guiding device having an expandable guiding member so as to facilitate and overcome the difficulties associated with obtaining contra-lateral leg access of a bifurcated stent or a bifurcated stent graft with a second guidewire and a method for treating abdominal aortic aneurysms with such a device. The guiding device comprises a pre-loaded second wire positioned within the contra-lateral leg which facilitates access to said leg in accordance with the present invention.

Abstract: An adjustable implant is disclosed herein. The adjustable implant may comprise a shell including membrane and a base and having a first diameter in a plane parallel to the base. A band may be disposed within the shell. The band may have a first end and a second end connected to a spool. The band may be in a round (e.g., elliptical) configuration having a second diameter in the plane that is less than the first diameter. By wrapping the band onto the spool, the diameter of the band may be decreased and the height of the implant may be increased. By unwrapping the band from the spool, the diameter of the band may be increased and the height of the implant may be decreased.

Abstract: A stator assembly has coils in a distributed winding configuration. A poly-phase switched reluctance motor assembly 3002 may include a stator assembly with multiple coils in a distributed winding configuration. The stator assembly may have a central bore into which a rotor assembly having multiple poles is received and configured to rotate. A method of controlling a switched reluctance motor may include at least three phases wherein during each conduction period a first phase is energized with negative direction current, a second phase is energized with positive current and there is at least one non-energized phase. During each commutation period either the first phase or second phase switches off to a non-energized state and one of the non-energized phases switches on to an energized state with the same direction current as the first or second phase that was switched off. The switched reluctance motor may include a distributed winding configuration.

Abstract: A method of a control system controls an inductance motor in a device that may include an impeller using a pressure compensation control system. The control system may be implemented in a respiratory pressure therapy device. The control system may include a sensor configured to provide a pressure signal indicative of the pressure of a flow of fluid produced by the device. A measured pressure may be compared to a set pressure to determine a pressure error. A slip frequency may be adjusted as a function of the pressure error in an attempt to eliminate or minimise the pressure error.

According to one aspect there is provided a computer-implemented verifiable data storage method comprising: receiving a product serial number; receiving an account identifier; producing a non-invertible hash by operating on the product serial number and the account identifier; and causing the hash to be written to a secure distributed data store. According to another aspect there is provided a computer-implemented verification method comprising: receiving a product serial number; receiving an account identifier; producing a non-invertible hash by operating on the product serial number and the account identifier; searching a secure distributed data store for the hash; and depending on a result of the searching, providing confirmation or denial of the hash's presence in the secure distributed data store.

Abstract: Various embodiments of an adjustable implant are disclosed herein. The adjustable implant comprises a hydraulic mechanism disposed within the shell, which includes a first component and a second component that is moveable with respect to the first component, and a band with a first and second end disposed within the shell in a round (e.g., elliptical) configuration having a second diameter in the plane that is less than the first diameter. In some embodiments, the first end of the band may be connected to the first component and the second end of the band may be connected to the second component. In some embodiments, the mechanism may include a fluid and a pump that has a first actuator comprising a first chamber and a second actuator comprising a second chamber. Depressing the first actuator causes the first component to move in a first direction, which reduces the diameter of the band and increases the height of the implant.

Abstract: The locations of flowers on a plant, rather than the locations of agricultural products produced from such flowers, are used to facilitate the performance of harvesting and other agricultural operations in robotic agricultural applications. In some implementations, the identified location of a fruit-producing flower may be used by a robotic device to apply an indicator tag to a flowering plant proximate the flower for later identification when performing various types of directed and automated agricultural operations. In other implementations, the identified location of a fruit-producing flower may be used by a robotic device to anchor a stem of a flowering plant to a predetermined location such that the location of the flower, and of any fruit(s) later produced by such flower, are controlled and/or known when performing subsequent agricultural operations.
