  • Publication number: 20210380060
    Abstract: An electronic control unit for a restraint control module comprises a PSI5 communications interface configured to communicate with a remote sensor using a current-modulated signal with PSI5 compliance upon a two-wire interconnection. The PSI5 communications interface includes a signal driver configured to apply a signal voltage to a first signal terminal for driving current to the remote sensor via the two-wire interconnection. The PSI5 communications interface also includes a second signal terminal providing a return path for the current; and a resistor within the return path of the PSI5 communications interface. Several different alternative impedance balancing and damping circuits are provided to provide the resistor. The alternative impedance balancing and damping circuits include passive and active resistors. The impedance balancing and damping circuit may also provide current protection against damage due to fault currents.

  • Publication number: 20210372298
    Abstract: A valvetrain suitable for an internal combustion engine of a type that includes a combustion chamber, a moveable valve having a seat formed within the combustion chamber, and a camshaft. The valvetrain includes a rocker arm assembly having a rocker arm and an electrical device that either configures the rocker arm assembly or provides position feedback for a part of the rocker arm assembly. The valvetrain includes a framework that fits around a spark plug tube while holding a component of a circuit that includes the electrical device in a position adjacent the rocker arm assembly. The position may place the component in contact with or very close to the rocker arm assembly. This framework structure may effectively utilize the available space under a valve cover while facilitating correct positioning of the component in relation to the rocker arm assembly.

  • Patent number: 11038723
    Abstract: At least some aspects of the present disclosure provide for a method. In at least one example, the method includes applying first equalization to a received data signal to generate an equalizer signal and comparing the equalized signal to each of a plurality of reference voltages for a predetermined period of time per respective reference voltage to generate a comparison result. The method further includes determining a plurality of counts with each count of the plurality of counts uniquely corresponding to a number of rising edges in the comparison result for each of the plurality of reference voltages. The method further includes comparing at least one of the plurality of counts to at least another of the plurality of counts to determine a relationship among the plurality of counts and applying second equalization to the received data signal based on the determined relationship among the plurality of counts.

  • Patent number: 11003605
    Abstract: An input/output (I/O) level shifter for a subscriber identification module (SIM) interface includes a controller configured to apply a first enable signal to turn ON a first transmitter when the direction of packet flow is from an interface device to a SIM card, and is configured to apply a second enable signal to turn ON a second transmitter when the direction of packet flow is from the SIM card to the interface device. The controller is configured to not apply the first and the second enable signals concurrently. The controller selectively controls the ON/OFF period of the first and the second transmitter to maintain half-duplex communication on the interface I/O line and the SIM I/O line to prevent undesired positive data feedback.

  • Publication number: 20210120656
    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.
