  • Publication number: 20190146684
    Abstract: Systems and methods for quality of service (QoS) using adaptive command fetching are disclosed. NVM Express (NVMe) implements a paired submission queue and completion queue mechanism, with host software on the host device placing commands into the submission queue. The memory device processes the commands through various phases including fetching, processing, posting a completion message, and sending an interrupt to the host. NVMe also includes an NVMe virtualization environment, which uses a subsystem with multiple controllers to provide virtual or physical hosts direct I/O access. QoS may be used so that the NVMe processes in the virtualization environment receive sufficient resources. In particular, bandwidth assigned to a submission queue may be considered when processing of commands (such as fetching of commands). In the event that the bandwidth assigned to the submission queue is exceeded, the processing of the commands (such as the fetching of the commands) may be delayed.

  • Patent number: 10125814
    Abstract: A magnetic bearing retains a rotatable shaft in a selected position by magnetic coupling between a circular magnet and one or more magnet arrays. Each magnetic coupling completes a magnetic circuit. The magnet arrays focus magnetic flux towards the circular magnet to facilitate magnetic coupling. Magnet arrays configured in Halbach series may be employed. Magnet arrays configured as electromagnets may also be employed. The shaft may be attached either to the circular magnet or the magnet arrays. Shaft rotation does not affect the magnetic circuit, but axial displacement of the shaft disrupts the magnetic circuit and increases magnetic reluctance. Increasing magnetic reluctance inhibits axial displacement. The shaft thereby supports a load while rotating freely, constrained to a selected position by forces of magnetic reluctance. A centering bearing may be employed to maintain gap distance between circular magnet and one or more magnet arrays.

  • Publication number: 20180166946
    Abstract: A flywheel energy storage device includes the Halbach Motor/Generator with rolling biphasic coil control, continuously variable torque transfer via magnetic induction and a reluctance magnetic levitation system known as the Axial-Loading Magnetic Reluctance Device. Electric energy input turns the magnetically coupled rotors of the Halbach motor, and torque is transferred to a flywheel through a copper cylinder variably inserted between the Halbach magnet rotors. In idle mode, the energy is stored kinetically in the spinning flywheel, which is levitated by a permanent magnet bearing. Electric energy output is achieved by transferring torque from the flywheel through the copper cylinder to the rotors of the Halbach Generator by magnetic induction. Rolling biphasic motor control includes dividing Halbach motor coils into increments, then energizing groups of contiguous increments into virtual coils, which revolve in tandem with the magnet rotors so to achieve continuous and optimal torque.

  • Publication number: 20180143091
    Abstract: An elastic strain sensor can be incorporated into an artificial skin that can sense flexing by the underlying support structure of the skin to detect and track motion of the support structure. The unidirectional elastic strain sensor can be formed by filling two or more channels in an elastic substrate material with a conductive liquid. At the ends of the channels, a loop port connects the channels to form a serpentine channel. The channels extend along the direction of strain and the loop portions have sufficiently large cross-sectional area in the direction transverse to the direction of strain that the sensor is unidirectional. The resistance is measured at the ends of the serpentine channel and can be used to determine the strain on the sensor. Additional channels can be added to increase the sensitivity of the sensor. The sensors can be stacked on top of each other to increase the sensitivity of the sensor.

  • Patent number: 9876407
    Abstract: A motor includes two magnetically coupled, coaxially-nested Halbach cylinder rotors, one of which passes through a toroidal series of at least two stator coils while the other is attached to an axle or other means of transferring mechanical power. An embodiment is described comprising an additional third Halbach cylinder rotor in which a circumferential arrangement of permanent magnets is mounted rotatably and proximally outside the stator coils, coaxial with the stator coils. Adjacent stator coils are configured so as to produce opposing magnetic fields upon energizing of the motor. Alternating the current to the stator coils induces movement in the rotor. Commutation can occur brushlessly, or the motor can be configured to function without commutation by varying the frequency of the alternating current, and can be configured to operate by either DC or AC current. Alternatively, the rotor may be driven to generate an electric current in the stator.
