Abstract: A software defined button includes a force sensor and a haptic output element. The button further includes an immutable logic core and a mutable logic core. The mutable logic core is configured to define one or more thresholds against which input received from the force sensor can be compared to determine whether a user input has been provided. The immutable logic core is configured to verify actual force input has been received when the mutable logic core signals that user input has been received. In response to receiving a verified force input, the haptic output element can be caused to be driven by one of the mutable or immutable logic cores to provide a haptic output to a user.

Methods of use are also provided, including automated priming sequences, blood return sequences, and dynamic balancing methods for controlling a rate of fluid transfer during different types of dialysis, including hemodialysis, ultrafiltration, and hemodiafiltration.

Abstract: An impact mill using hammers to strike particles and reduce their size as the material progresses through a grinding chamber. Baffles are provided in the grinding chamber, adjacent the interior wall thereof, concentrically about the drive shaft of the mill. The baffles are adjacent to the hammers in the area of hammer sweep and form a path for the material using the flow of air through the mill and the swing of hammers to keep material from falling within the mill and remaining in the hammer sweep area. A variable speed motor varies the rate of movement of the hammers to increase or decrease the rate of strike of hammers to more efficiently and effectively reduce the material passing therethrough. The baffles can be retrofit into existing mills and can be created in angular sections with the lining of the grinding chamber for modular installation and removal.

Abstract: A hammermill, such as an imp mill 10, for pulverizing material includes a housing 16 defining a grinding chamber 14 having a grinding apparatus 12 disposed therein. The material is fed into the grinding chamber to the grinding apparatus through an inlet conduit 24, and the resulting ground material is directed from the grinding chamber through an outlet conduit 28. The grinding apparatus includes a plurality of hammer disks 32 axially spaced along a rotor 34, wherein disks 32 are disposed within the grinding chamber 14. A plurality of rows 41-46 of hammers 30 is attached to the hammer disks 32. The hammers 30 of each respective row of hammers are circumferentially spaced around the hammer disks 32, wherein each row of hammers is formed to provide generally uniform wear across each row of hammers. The uniform wear may be achieved by forming the hammers 30 of different hardness or wear resistant qualities, and/or configuring the rows of hammers with different shapes.
