  • Publication number: 20230341234
    Abstract: In various examples, a lane planner for generating lane planner output data based on a state and probabilistic action space is provided. A driving system—that operates based on a hierarchical drive planning framework—includes the lane planner and other planning and control components. The lane planner processes lane planner input data (e.g., large lane graph, source node, target node) to generate lane planner output data (e.g., expected time rewards). The driving system can also include a route planner (e.g., a first planning layer) that operates to provide the lane planner input data to the lane planner. The lane planner operates as second planning layer that processes the lane planner input data based at least in part on a state and probabilistic action space of the large lane graph and calculates a time cost associated with navigating from a source node to a target node in the large lane graph.

  • Publication number: 20230290735
    Abstract: An Integrated Circuit (IC) package has a ferrite-dielectric shield between a planar inductor coil and a semiconductor chip. The shield blocks Electro-Magnetic Interference (EMI) generated by currents in the inductor coil from reaching the semiconductor chip. The shield has a ferrite layer surrounded by upper and lower dielectric laminate layers to prevent electrical shorts. The center end of the inductor coil connects to the semiconductor chip through a center post that fits through an opening in the shield that is over the air core center of the inductor coil. The center post can connect to a die attach pad that the semiconductor chip is mounted to. Bonding wires connect pads on the semiconductor chip to lead-frame pads on lead-frame risers that end at external package connectors. The outer end of the inductor coil connects to lead-frame outer risers also having external package connectors such as pins or bonding balls.

  • Patent number: 11258364
    Abstract: A re-configurable bank of DC-DC converters has many channels, each with a DC-DC converter and a controller that senses the channel's output voltage and current to adjust a duty cycle of switch signals to the DC-DC converter. A serial bus connects to all controllers and writes digital voltage and current control targets into each controller. The controller has Digital-to-Analog Converters (DACs) that convert the targets to analog voltages that are compared to sensed output voltage and current. The comparison results are compared to a sawtooth wave to generate pulses of the switch signals that have a duty cycle adjusted for the target comparisons. In combined mode, a primary channel's controller generates switch signals for secondary channels having outputs shorted to the primary channel. Secondary channels have a mux to select switch signals from the primary controller during combined mode, and from the secondary controller during separated mode.

  • Patent number: 11206014
    Abstract: A modulator spreads the spectrum of a generated clock to reduce Electro-Magnetic Interference (EMI). A capacitor is charged by a variable current to generate a ramp voltage that is compared to a reference to end a clock cycle and discharge the capacitor. An up-down counter drives a Digital-to-Analog Converter (DAC) that controls the variable charging current to provide triangle modulation. A smaller offset current is added or subtracted for cubic modulation when the up-down counter reaches its minimum count. A frequency divider that clocks the up-down counter also clocks a Linear-Feedback Shift-Register (LFSR) to that controls pseudo-random current sources that further modulate variable current and frequency. The LFSR is clocked with the up-down counter to modulate each frequency step, or only at the minimum count to randomly modulate at the minimum frequency. Binary-weighted bits from the up-down counter to the DAC are swapped to modulate the frequency step size.
