  • Patent number: 10997095
    Abstract: Systems, apparatuses, and methods for training procedures on reference voltages and sampling times associated with symbols communicated with a memory device are described. The training procedures may be configured to compensate for variations that may occur in different symbols of a signal. For example, an individual training operation may be performed for each reference voltage within a first unit interval. These individual training operations may allow a reference voltage of the first unit interval to be positionable independent of other reference voltages in the same unit interval or in different unit intervals. In another example, an individual training operation may be performed for the sampling time associated with a reference voltage. These individual training operations may allow a sampling time associated with a reference voltage in the first unit interval to be positionable independent of other sampling times in the same unit interval or in different unit intervals.

  • Patent number: 10998011
    Abstract: Methods, systems, and devices for drive strength calibration for multi-level signaling are described. A driver may be configured to have an initial drive strength and to drive an output pin of a transmitting device toward an intermediate voltage level of a multi-level modulation scheme, where the output pin is coupled with a receiving device via a channel. The receiving device may generate, and the transmitting device may receive, a feedback signal indicating a relationship between the resulting voltage of the channel and an value for the intermediate voltage level. The transmitting device may determine and configure the driver to use an adjusted drive strength for the intermediate voltage level based on the feedback signal. The driver may be calibrated (e.g., independently) for each intermediate voltage level of the multi-level modulation scheme. Further, the driver may be calibrated for the associated channel.

  • Publication number: 20210113856
    Abstract: In various embodiments, a radiation therapy method can include loading a planning image of a target in a human. In addition, the position of the target can be monitored. A computation can be made of an occurrence of substantial alignment between the position of the target and the target of the planning image. Furthermore, after the computing, a beam of radiation is triggered to deliver a dosage to the target in a short period of time (e.g., less than a second).

  • Patent number: 4302333
    Abstract: A backpressure grid plate is provided for a pressure filtration system of the type comprising a housing with an inlet and outlet for conducting fluid to be treated, a filter disposed in the housing between said inlet and outlet, and a backpressure grid means arranged between the filter and the inlet. The backpressure grid means comprises a plate containing minute openings which are equal in size and distributed unevenly over the surface area of the plate in such manner that the surface distribution density of the openings is lowest within an inner impact area of the plate which receives inflowing fluid to be filtered and is highest within a proximity area of the plate located immediately adjacent to and surrounding the impact area. The surface distribution density of the openings within an outer area surrounding the proximity area is lower than that of the proximity area and higher than that of the impact area.

  • Patent number: 4229306
    Abstract: A housing for single-use pressure filtration units comprises upper and lower parts. A filter element is to be clamped between the housing parts. The upper housing part, preferably molded in one piece of synthetic material, includes a plurality of radial ribs which hold the filter element down, and a baffle disk supported solely by the ribs. The disk is spaced beneath the axial inlet duct to prevent direct impingement of axially incoming pressurized fluid against the filter element. Only some of the ribs support the disk, the remaining ribs terminating short of the disk to promote uniform radial distribution of fluid deflected by the disk. Radially inner ends of the disk support ribs are inclined downwardly and inwardly and act in funnel-like fashion on the inflowing fluid.

  • Patent number: 4136029
    Abstract: A pressure filtration apparatus including an upper portion with an inflow channel and a discharge channel for the concentrate and a lower portion with a filter support and a discharge channel for the filtrate, the upper and lower portions being releaseably connectable with one another while forming a pressure space. The apparatus contains a distributor plate whose underside is disposed parallel to the upper side of the filter and snugly above the latter while forming an intervening space, and in the center of which is an opening for the concentrate discharge channel. The outer edge of the distributor plate forms a small annular opening which extends all around closely against a basically vertically interior of the pressure space. The top side of the distributor plate has a peripherally raised outer edge which while forming a narrow annular clearance extends to close up against a downwardly pointing horizontal interior wall of the upper portion.

  • Patent number: 4127486
    Abstract: A pressure filtration cell includes a reservoir for liquid to be filtered, a filter at the bottom of the reservoir, and a manually actuable pump for supplying compressed air. The pump is detachable from the reservoir. The air is introduced near the bottom of the reservoir closely adjacent the filter so as to create turbulence in the liquid and across the filter. The turbulence is of a pulsating nature due to the intermittent operation of the pump. Thus, the pump is easily portable for use anywhere and creates a "dynamic" filtration process even without a mechanical stirrer. If used in a laboratory, the cell can be provided with a rotary, magnetically operated stirrer mounted on a relatively short axle.

  • Patent number: 4113144
    Abstract: A syringe of the slide piston pump type is adapted to overcome a pressure resistance at its outlet as may be provided, for instance, by a filter in communication with the outlet and through which the syringe is to pump a medium, particularly a liquid medium, for filtration. The syringe comprises a cylinder containing a piston, and a piston rod. The piston rod is fixed to a second piston sliding within a longitudinal bore in the first-mentioned piston. The bore and the second piston cooperate to define an air-filled pressure chamber connected to a cylinder chamber, defined by the first piston and the cylinder, by a valve. Inward movement of the piston rod produces an over-pressure (e.g. 16 atmospheres) in the pressure chamber to open the valve to apply the over-pressure to the liquid or other medium in the cylinder chamber to overcome the pressure resistance of the filter and enable the liquid to be forced through the filter.
