摘要:
Systems, methods, and apparatus for adaptively modifying latency times governing entry of a PCIe interface into low power states are described. A method performed by a controller of a PCIe interface includes determining that a burst of data is being transmitted on a PCIe link, configuring a timer to signal when an entry latency period has elapsed after determining that a PCIe link has entered an idle state, causing one or more circuits of the PCIe interface to enter a low-power state when the timer signals that the entry latency period has elapsed before the PCIe link becomes active, and increasing the entry latency period when a number of entries of the PCIe interface to the low-power state that occurs during transmission of the burst of data exceeds a threshold maximum number.

A method for initiating fingerprint capture in an electronic device is described. The device includes a touch screen with a sensing region, a touch controller, a fingerprint controller, and a host. The device is placed in a low power doze mode where the fingerprint controller is in a low power state and the device scans for an object proximate to the sensing region. When an object is proximate to the sensing region, the device executes a validation mode to determine whether the object is a fingerprint. When a fingerprint is detected, the device sends a wake up signal to the fingerprint controller and places the fingerprint controller in a high power mode. One or more fingerprint images are then captured.

A device for detecting biometric information is provided. The device includes a housing, a fastener coupled to a part of the housing and detachably attached to a part of a user's body, at least one first sensor configured to detect the motion of the electronic device, at least one second sensor configured to detect a change in the user's body, a memory, and a processor electrically connected to the at least one first sensor, the at least one second sensor, and the memory. The memory may store instructions that configure the processor, when being executed, to determine whether the electronic device is worn on a part of the user's body using the at least one first sensor, acquire information on the motion of the electronic device using at least a part of the at least one first sensor for a second period of time shortly before and/or immediately after a first period of time selected passes from the time when the electronic device is worn on a part of the user's body, and activate the at least one second sensor based on at least a part of the information on the motion.

Techniques for low-power implementation of a Universal Serial Bus (USB) Type-C connector subsystem are described herein. In an example embodiment, an integrated circuit (IC) chip device comprises a Universal Serial Bus (USB) Type-C subsystem. The Type-C subsystem is configured to operate an Ra termination circuit that consumes no more than ΙΟΟμΑ of current after the Ra termination circuit is applied to a Vconn line of the Type-C subsystem, and/or to operate one or more standby reference circuits in a deep-sleep state of the device to perform detection on a Configuration Channel (CC) line of the Type-C subsystem, where the device consumes no more than 1ΟΟμΑ of current in the deep-sleep state.

摘要:
According to an example of managing a universal serial bus ("USB"), a device connected to a USB hub controller is sensed and a USB information scheme from the device is fetched. A power requirement of the device is determined through the USB information scheme, and a total power consumption of a plurality of devices connected to the USB hub controller is calculated. USB information scheme data to display to a user and a data display arrangement are determined, and a monitor scalar is instructed to display the USB information scheme in the determined data display arrangement. Power to the device is distributed based on the total power consumption of all devices connected to the hub controller and a user setting.
