Abstract: Disclosed herein is a dual-active bridge converter and methods of operating the same. The dual-active bridge converter can include a transformer, a DC-AC converter, an AC-DC converter, and/or a control device. The DC-AC converter can be coupled to a first DC bus and a primary side of the transformer. The AC-DC converter can be coupled to a secondary side of the transformer and a second DC bus. The control device can send a first PWM signal to the DC-AC converter and a second PWM signal to the AC-DC converter. The first and second PWM signals can initiate the output voltage at zero, add jump edges at odd-numbered current harmonics, or make a phase of the input voltage trail a phase of the output voltage of the DC-AC converter. The control device can adjust the PWM signals for transformer current regulation or pulse overlap control.

Abstract: A distributed display method provides different parts of an application interface that are collaboratively displayed on a plurality of terminals, so that manners for collaborative display between the plurality of terminals are more flexible and richer. A first terminal displays a first interface including a first part and a second part. When the first terminal detects that a preset condition is met, the first terminal displays a second interface, where the second interface includes the first part and does not include the second part; and the first terminal notifies a second terminal to display a third interface, where the third interface includes the second part and does not include the first part.

Abstract: A ripple control method for a modular cascaded power conversion device is provided. The method obtains, according to a grid voltage vector of three-phase AC power, a second-order fluctuating voltage superposition vector representing the total amount of second-order fluctuating voltages on respective floating DC sides of the three phases; determines a single-phase power control amount of each phase to be transferred from the floating DC sides to a low-voltage DC side; determines a single-module power control amount of each power module to be transferred to a low-voltage DC side thereof; and generates a single-module control signal for controlling the power module, so as to transfer a second-order fluctuating voltage on a floating DC side of the power module to the low-voltage DC side thereof. A modular cascaded power conversion device is also provided.

Abstract: A component for a vehicle interior may comprise a light guide to allow light transmission from a light source for a user interface, and a cover to cover the light guide. The user interface may be presented at the cover. The cover may comprise a depression in an inner surface of the cover and the light guide may comprise a projection comprising a light-transmissive resin fit within the depression. The projection may comprise an icon to be presented at the user interface when illuminated, and to be hidden by the cover when not illuminated. The user interface may comprise a light display and an input device connected to a sensor. The icon may comprise an image. The cover thickness may be greater than the projection height. The component may comprise a steering wheel, console, floor console, center console, instrument panel, door panel, dashboard, display, armrest, or cockpit.

Abstract: A method includes receiving a burst access request for transfer of data between a memory and a first bus. The burst access request specifies an amount of data that is at least a multiple of an amount of data transferred in one beat. A single memory request is issued, instructing the memory to transfer the specified amount of data between the memory and a buffer coupled to the first bus. The specified amount of data is transferred between the buffer and the first bus in a plurality of beats.

Abstract: An apparatus and method are provided for extracting connection information from a traffic header in a communications network. The apparatus includes a first storage element containing a first look-up table for determining a first data packet header offset and data size for extracting a communications protocol type from the header and a second storage element containing a second look-up table for determining from the communications protocol type a second data packet header offset and second data size for extracting a connection address from the header. The storage elements may be in the form of content-addressable memories. Exception handling and hardware initialization can be controlled by a system processor.

Abstract: A buffer circuit for use in a node in a network-based data transport system is configurable for providing channel status information of all channels associated with a given signal in the network-based data transport system. The buffer circuit includes a memory and a controller coupled to the memory. The controller is the operative: (i) to receive channel status information from a plurality of different channel status sources; (ii) to select one of the channel status sources for supplying the channel status information at a given point in time; and (iii) to store the channel status information corresponding to the selected channel status source in the memory.
