  • Patent number: 10537671
    Abstract: A hemodialysis apparatus comprising diaphragm pumps for the movement of both dialysate and blood, and under the control of a controller, is capable of detecting blood flow conditions that give rise to an alarm and implement procedures to adjust, pause, or halt the pumping of dialysate and/or blood. The controller can direct the application of a time-varying pressure to fluid in the control chamber of a blood pump, and monitor the resulting pressure waveform during a fill stroke of the blood pump. A deviation of the measured pressure variation from an expected value can give rise to an alert to a user and to the initiation of an adjustment, pause, or cessation of the dialysate pump's activity.

  • Patent number: 10449280
    Abstract: Disclosed are hemodialysis and similar dialysis systems including fluid flow circuits. Hemodialysis systems may include a blood flow path, and a dialysate flow path including balancing, mixing, and/or a directing circuits. Preparation of dialysate may be decoupled from patient dialysis. Circuits may be defined within one or more cassettes. The fluid circuit and/or the various fluid flow paths may be isolated from electrical components. A gas supply may be provided that, when activated, is able to urge dialysate through the dialyzer and blood back to the patient. Such a system may be useful during a power failure. The hemodialysis system may also include fluid handling devices, such as pumps, valves, mixers, etc., actuated using a control fluid. The control fluid may be delivered to the fluid handling devices using a detachable external pump. The fluid handling devices may have a spheroid shape with a diaphragm dividing it into two compartments.

  • Patent number: 10443591
    Abstract: Hemodialysis and similar dialysis systems including a variety of systems and methods that make hemodialysis more efficient, easier, and/or more affordable, and include new fluid circuits for fluid flow in hemodialysis systems and a blood pump. The blood pump is configured to pump blood to a dialyzer of a hemodialysis apparatus and comprises a pneumatically actuated or controlled reciprocating diaphragm pump. The diaphragm of the pump comprises a flexible membrane formed or molded to conform to a curved inner wall of a pumping chamber or control chamber of the pump, and the diaphragm is pre-formed or molded to have a control side taking a convex shape, so that any elastic tension on the diaphragm is minimized when fully extended into a control chamber of the pump.

  • Patent number: 7472485
    Abstract: An improved wheel alignment turntable for supporting a wheel of a vehicle. Embodiments include a turntable having a base, and a top plate for receiving the vehicle wheel, the top plate being mounted to an upper surface of the base for rotational and translational movement relative to the base. A pair of paddles, removably adjustably attachable to the base, engages a peripheral wall of the top plate for maintaining the top plate in a predetermined position relative to the base while the vehicle wheel is being positioned on the turntable. The paddles are easily removable when the wheel is supported on the turntable. A plurality of slide pads are removably mounted to a lower surface of the base, for enabling sliding motion between the turntable and a surface of a lift without damaging paint on the surface of the lift. The slide pads are stackable against one another for adjusting height of the turntable relative to the lift.

  • Patent number: 7449766
    Abstract: Methods to form contact openings and allow the formation of self-aligned contacts for use in the manufacture of semiconductor devices are described. During formation of a multi-layered resist, a hard mask material is introduced beneath an anti-reflective coating to be used as an etch stop layer. The multi-layered resist is patterned and etched, to transfer the desired contact pattern to a substrate material, such as a silicon substrate, to form contact openings therein. The contact openings provide for the formation of self-aligned contacts therein.

  • Patent number: 7369222
    Abstract: In a vehicle alignment system an optical sensing mechanism is structurally coupled to a vehicle supporting lift for movement in unison with the lift so that the field of view of the sensing mechanism encompasses a wheel of a vehicle positioned on the lift during lift movement. Sensing modules may be selectively placed so that they are in correspondence with the vehicle wheel base. Modules may be deployed to extend outwardly from the lift, for viewing the wheel during an alignment procedure, or retract to a adjacent the lift for stowing. A protective cover extends above the sensing modules in the retracted position.

  • Patent number: 7329618
    Abstract: An ion implanting method includes forming a pair of spaced and adjacent features projecting outwardly from a substrate. At least outermost portions of the pair of spaced features are laterally pulled away from one another with a patterned photoresist layer received over the features and which has an opening therein received intermediate the pair of spaced features. While such spaced features are laterally pulled, a species is ion implanted into substrate material which is received lower than the pair of spaced features. After the ion implanting, the patterned photoresist layer is removed from the substrate. Other aspects and implementations are contemplated.
