  • Patent number: 11843484
    Abstract: A system for selecting an equalizer setting of an equalizer to equalize signals received via a communications link. Starting with a first (e.g., minimum) equalizer setting and a threshold voltage near the mid-eye voltage of the equalized output signal, the system estimates the amplitude of the inner eye of the equalized output signal by comparing the equalized output signal to a series of threshold voltages. If the amplitude of the equalized output signal is less than ideal, the system dynamically increases the equalizer setting. The system quickly converges on the equalizer setting for the communication link because, rather than comparing the output signal at every voltage offset using every equalizer setting, the system only evaluates the equalizer settings necessary to select the equalizer setting for the communications link and uses only the voltage offsets necessary to evaluate each equalizer setting.

  • Publication number: 20230337879
    Abstract: A dirt separator for a vacuum cleaner includes a chamber having an inlet through which dirt-laden fluid enters and an outlet through which cleansed fluid exits the chamber. A disc located at the outlet rotates about a rotational axis and comprises holes through which the cleansed fluid passes. The dirt-laden fluid enters the chamber along a flow axis that intersects the disc.

  • Patent number: 11792361
    Abstract: A redriver system adapted for coupling to a first device and to a second device includes first and second transmitter drivers and a snoop circuit. The first transmitter driver has a first enable input. The second transmitter driver has a second enable input. The snoop circuit is coupled to the first and second enable inputs. The snoop circuit is configured to determine whether the first device and the second device are to operate according to a first protocol. Responsive to the snoop circuit determining that the first and second devices are to operate according to the first protocol, the snoop circuit enables the first transmitter driver and disables the second transmitter driver. Responsive to the snoop circuit determining that the first and second devices are not to operate according to the first protocol, the snoop circuit disables the first transmitter driver and enables the second transmitter driver.

  • Patent number: 11765811
    Abstract: Embodiments of a laser system having an extremely large number of small pulsed lasers for irradiating small targets in inertial confinement fusion experiments, high energy density physics experiments, and inertial fusion power plants is more flexible than existing laser systems. Embodiments facilitate finer control of critical features of laser pulses for inertial fusion, as well as significant reduction in development costs and expansion of the community involved in the research relative to existing laser systems. Embodiments produce smooth intensity profiles at the target, large bandwidth that is over two orders of magnitude greater than existing laser systems, and fine control over laser wavelengths, focal properties, temporal pulse shape, and illumination geometry. Properties of each of the small pulsed lasers are individually selectable.

  • Publication number: 20230092178
    Abstract: Apparatus and methods are disclosed for correcting deformities in a patient's foot. In one example, a metatarsus adductus is addressed using a pin placement guide that is angulated to be placed in alignment with a cuneiform and a metatarsal, such that the TMT joint can be subsequently cut, and the metatarsal moved into proper alignment. Th pin placement guide can be a variable angle guide, or a kit of fixed-angle pin placement guides can be provided.

  • Publication number: 20220370211
    Abstract: Methods and apparatus are disclosed for excising a joint between first and second bones to define a resected joint, approximating the first and second bones to reduce the resected joint, and fixing the first and second bones relative to each other. The excising step can be performed using a cut guide that is movable from a first orientation to cut the first bone to a second orientation to cut the second bone. A compressor block can be driven over temporary fixation members that extends into the first and second bones to reduce the resected joint. A staple, along or in combination with other fixation elements, can then permanently fix the first bone to the second bone.

  • Patent number: 11486272
    Abstract: A switching roller finger follower comprises an inner arm assembly. A pair of outer arms surround the inner arm assembly. A pivot axle connects the inner arm assembly to pivot with respect to the pair of outer arms from a starting position to a lost motion position. A latch assembly comprises a latch selectively movable from a latched position latching the inner arm assembly to move dependent with the outer arms and an unlatched position unlatching the inner arm assembly to pivot independent of the outer arms. A stop pin spans between the pair of outer arms and through an inner port in an axle of inner arm assembly. The stop pin comprises a clearance fit with the inner port, and the stop pin is configured pivotable independent of the outer arms. At least one return spring biases the stop pin toward the starting position.
