Abstract: A system, machine, device, manufacture, circuit, and/or a method that can comprise and/or relate to active thrust bearings and/or active radial bearings that each utilize electromagnetic and permanent magnetic flux paths that can influence a location of a shaft of a rotating machine in response to internal and/or external forces applied to the shaft.

Abstract: Partial body-weight support systems and methods for human gait training are disclosed. The system may include a motor and a cord coupled to the motor, the cord and the motor providing at least partial body-weight support to a user during human gait training. The system may also include a controller that actively adjusts the operation of the motor based upon measured gait parameters. The method may include coupling a human to a motor and monitoring the gait of the human while the human is walking to produce a signal indicative of the gait of the human. The method may also include varying the operation of the motor based on the signal so as to assist the human in attaining a predetermined gait pattern.

Abstract: A blood pump has an impeller rotatably disposed and magnetically suspended within a cavity of a stator by a plurality of magnetic bearings (passive permanent and active electromagnetic) having impeller magnets on the impeller and stator magnets or coils/poles on the stator. A motor includes impeller magnets on the impeller and coils/poles associated with the stator. A single, annular blood flow path extends axially through the cavity between the impeller and the stator, and between the impeller magnets on the impeller and the stator magnets or the coils/poles on the stator.

Abstract: A blood pump has an impeller rotatably disposed and magnetically suspended within a cavity of a stator by a plurality of magnetic bearings including an axial bearing to support the impeller axially in the cavity. The axial bearing includes adjacent impeller magnets and adjacent stator magnets with axially aligned polarities and reverse polarities with respect to adjacent magnets. A motor includes impeller magnets on the impeller and coils and poles associated with the stator. Radial permanent magnet and electromagnetic bearings are also included. The magnetic bearings and the motor have stator magnets or coils and poles disposed radially across the fluid passage from corresponding impeller magnets to define an annular gap positioned radially between the impeller and the stator, and positioned radially between all of the plurality of magnetic bearings, creating a straight through blood path without secondary flow paths.

Abstract: A polygonal, indexable cutting insert having a positive rake and a cutting edge having a truncated sinusoidal form. Serrations on the side faces extend perpendicular to the top face.

Abstract: A cutting guide for a power handsaw which cutting guide is of simple and inexpensive construction; is easily transported and used; and is particularly adapted to hold the material to be cut along the desired line of cut, whereby to prevent shivering upon cutting. This cutting guide includes an elongated support plate or strip, a guide ridge projecting from the top face of the support plate and forming a longitudinal guide for a power handsaw running lengthwise of the support plate. The opposite lateral edges of the support plate are arranged parallel and at predetermined and distinct spacings from the guide ridge.

Abstract: A miter table assembly adapted to produce miter cuts with a power saw, such as a circular handsaw, and which is particularly adapted to be safe to operate and readily collapsible for easy transportation from one job site to another. This miter table assembly comprises a table top, hollow legs pivoted to the table top, bars or struts each removably engaging a pair of legs to hold the same in operative position and stowable in a hollow leg for transportation, an elongated base with a channel extending transversely thereof, a guide frame pivoting on top of the elongated base about an upright pivot axis, defining a straight slot upwardly registering with the transverse channel and adapted to slidably support and guide a power handsaw, stopping devices secured to the guide frame to prevent falling of the saw at either end of the slot and allowing selective removal of the saw, and clamping levers on opposite sides of the channel and of the base to clamp both cut pieces of work on either side of the base.
