  • Publication number: 20210318738
    Abstract: Methods and apparatus for enhanced power delivery between devices. In one embodiment, the power delivery is enhanced relative to legacy capabilities, and a source device negotiates with a sink device to establish a high-voltage (HV) power contract. In one variant, such HV operation enables power delivery greater than the legacy USB-C standard maximum of 20 V and 100 W. In one implementation, the source, sink, and/or source and sink collectively ensure that multiple criteria relating to power delivery are met for the interface (i.e., source, the sink, and the interposed cable or power delivery medium). Multiple conditions, including enclosure construction compliance and device capabilities, must be cleared to ensure safety while operating beyond standard maximums. If the criteria are met, HV validation is complete, and the source may offer HV operation to the sink to establish the HV contract. Additional fail-safe mechanisms enable the HV contract to discontinue upon triggering.

  • Patent number: 10236697
    Abstract: Circuits, methods, and apparatus where a dongle or adapter may provide continuous power in the event of a disconnection of a charging device. One example may provide a dongle having a charge storage circuit. A charging device connected to the dongle may be used to power an accessory also connected to the dongle. Following a disconnection of the charging device, the dongle may use the charger storage circuit to provide power to the accessory for a first duration. After the first duration, a host device also connected to the dongle may provide power to the accessory via the dongle.

  • Patent number: 9494989
    Abstract: Circuits, methods, and apparatus that provide for the powering of active components in connector inserts at each end of a cable may in various ways. For example, where a host is coupled to a device that is not self-powered, the host may provide power for circuitry at each end of the cable. In various embodiments of the present invention, the device may request higher voltage from the host, such that more power can be delivered. In these cases, the device may regulate the voltage received from the host to a lower voltage, and then provide the lower voltage to circuitry at one or both ends of the cable. Where the host is connected to a device that is self-powered, the host and the self-powered device may power their respective connector insert circuits.

  • Patent number: 9477437
    Abstract: An electronic device selectively couples a head with links in a graphics processing unit to a currently selected display port in a pair of display ports. During operation, control logic in the electronic device monitors a pair of configuration signals from the pair of display ports, where the pair of configuration signals correspond to physical connections to the pair of display ports. Then, the control logic determines a selection control signal based on the monitored pair of configuration signals, a policy setting and a default display port, where the selection control signal specifies the currently selected display port. Moreover, the control logic provides the selection control signal to a multiplexer in the electronic device. Next, the multiplexer selectively couples the head with the links in the graphics processing unit to the currently selected display port based on the selection control signal.

  • Patent number: 8745430
    Abstract: The disclosed embodiments provide a system that facilitates synchronization between a first component and a second component connected to the first component via an interface in a computer system. During an active state of the interface, the system uses a local time base in the second component to generate a local clock signal that tracks a host clock signal from the first component. Next, during an inactive state of the interface, the system uses the local time base to maintain the local clock signal at the second component. Finally, during a subsequent active state of the interface after the inactive state, the system adjusts the local clock signal to remove clock drift between the local clock signal and the host clock signal.
