  • Publication number: 20230223852
    Abstract: A DC-DC converter is disclosed having an electronic switch network having a supply node, a ground node, an output node, a first inductor node, a second inductor node, and switch control inputs. An inductor is coupled between the first inductor node and the second inductor node. Control logic circuitry has switch control outputs coupled to the switch control inputs, wherein the control logic circuitry is configured to cause the electronic switch network to couple the inductor between the supply node and the output node to provide current flow through the inductor for a fixed time period, and at the end of the fixed time period to measure a check time period until the current flow through the inductor is equal to predetermined current value, and based upon the measured check time period to determine to switch between buck operation and boost operation or boost operation and buck operation.

  • Publication number: 20230126435
    Abstract: An automated package delivery machine, comprising: a housing with auto-lock doors; carousels; and robotic assemblies. The housing may substantially enclose the carousels and the robotic assemblies, and substantially prevents unwanted access to an interior of the housing. Each carousel may comprise a plurality of storage containers, a drive belt, a motor, and one or more rails. The storage containers may each have a plurality of slots, which are configured to accept and contain one or more packages to be delivered to one or more customers. The rails may form a loop track to which the storage containers are slidably engaged. The drive belt, driven by said motor, is configured to slidingly move the storage containers along the rails. The robotic assemblies are configured to remove the packages from the slots and deliver them to an interior side of the auto-lock doors.

  • Publication number: 20220255431
    Abstract: A direct-current to direct-current (DC-DC) converter circuit is provided. The DC-DC converter circuit is capable of generating a DC output voltage in a defined voltage range based on an input voltage. The DC-DC converter circuit can include a modulator circuit, an output filter circuit, and a compensator circuit. In a non-limiting example, the output filter circuit includes an inductor-capacitor (LC) circuit formed by an inductor and a multi-layer ceramic capacitor (MLCC). Notably, the MLCC can produce a variable capacitance in the defined voltage range due to inherent DC bias instability, thus risking stability of the DC-DC converter circuit. As such, a control circuit is configured to determine a configurable transconductance based on feedback of the output voltage and control the compensator circuit to operate accordingly. As such, it may be possible to mitigate the effect of MLCC capacitance variation, thus helping to maintain stability of the DC-DC converter circuit.

  • Patent number: 11294731
    Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for performing a joint simulation for satisfying multiple different coexisting commitments to allocate digital resources. In one aspect, a method includes accessing logged data for prior allocations of digital resources, where the logged data includes at least one property associated with respective allocations of the digital resources. Different allocations of the digital resources included in the logged data are assigned to different ones of the multiple different commitments. For each commitment to allocate digital resources, an expected required resource amount that results in the commitment being allocated at least a specified minimum resource based on the allocations of digital resources of the logged data that were assigned to the multiple different commitments is determined.

  • Patent number: 10826480
    Abstract: An integrated circuit includes a gate driver circuit that controls high side and low side transistors to operate in buck or boost mode. In buck operating mode, after switching off the low side transistor, the gate driver circuit controls the high side transistor in a constant current mode. After the low side transistor is disabled and no longer conducts current, then the gate driver circuit controls the high side transistor to operate in full-enhancement mode. In boost operating mode, after switching off the high side transistor, the gate driver circuit controls the low side transistor in a constant current mode. After the high side transistor is disabled, then the gate driver circuit controls the low side switching transistor to operate in full-enhancement mode. In both buck and boost operation, the gate driver circuit operates without dead time in which both the high side and low side transistors are off.
