Abstract: An electronic device includes a transmit buffer, a receive buffer, a communication port, and a controller. The controller is to: communicate with a target device via a data link established via the communication port; determine a throughput ratio between the transmit buffer and the receive buffer; in response to a determination that the throughput ratio is above a threshold, transmit a request to the target device to change an aspect of the data link, where the request includes a payload size indicating an amount of data to be transmitted from the electronic device to the target device; and in response to receiving a grant message associated with the request, increase an amount of transmit lanes within the data link from the electronic device to the target device.

Abstract: An example power delivery device includes a two-fold rotationally-symmetrical electrical connector with electrical connector pins having power delivery capability. A switch is operatively connected to the two-fold rotationally-symmetrical electrical connector to transmit power through the electrical connector pins. A power delivery controller to (i) identify a first set of electrical connector pins being used for transmission of electrical signals, (ii) identify a second set of electrical connector pins that are not being used for transmission of the electrical signals, and (iii) control the switch for power delivery between a first electrical device and a second electrical device through the first set of electrical connector pins and the second set of electrical connector pins.

Abstract: Example implementations relate to touch input detection. In some examples, a computing device may include a touch sensitive interface, a processing resource, and instructions executable by the processor. The instructions may be executable by the processor to cause the processor to detect a period of inactivity of the touch-sensitive interface; activate a one-dimensional scan for a touch input on the touch-sensitive interface in response to detecting the period of inactivity; and activate a two-dimensional scan for a touch input on the touch sensitive interface in response to detecting the period of inactivity.

Abstract: In one example in accordance with the present disclosure, an electronic device is described. An example electronic device includes a processor, a port to receive a connector of a peripheral device, and a power supply. An example power supply is to supply power to the processor and the peripheral device when connected to the electronic device. The example electronic device also includes an electronic device controller. The electronic device controller is to alter an amount of power from a first value to a second value to supply to the peripheral device based on an amount of power available from the power supply and a lower threshold power level that enables data communication from the peripheral device. The example electronic device also includes a power delivery controller. The power delivery controller is to provide the amount of power having the second value to the peripheral device based on an output from the electronic device controller.

Abstract: In some examples, an electronic device comprises a processor and a power circuit coupled to the processor. The power circuit is to provide power to the processor and to measure a current drawn from the power circuit by the processor. The electronic device also comprises a voltage regulator controller coupled to the processor and the power circuit. The voltage regulator controller is to receive a current usage prediction from the processor, receive the measurement from the power circuit, compare the current usage prediction and the measurement, and, based on the comparison, drive the power circuit in accordance with the measurement instead of the current usage prediction.

Abstract: In one example in accordance with the present disclosure, a computing device is described. An example computing device includes an integrated circuit chip having a first pin and a second pin. The example computing device also includes a conversion circuit. An example conversion circuit assigns an output of the first pin to a first voltage range and assigns the output of the first pin to a voltage value within the first voltage range based on a logical value of the output of the first pin. The example conversion circuit also assigns an output of the second pin to a second voltage range that is different from the first voltage range and assigns the output of the second pin to a voltage value within the second voltage range based on a logical value of the output of the second pin.
