摘要:
The present invention relates to the field of battery measurement for a mobile terminal, and provides a method and a device for measuring state of charge (SoC) of a mobile terminal The method comprises: measuring, after the mobile terminal enters a sleep/idle mode, battery parameters of the mobile terminal in accordance with a predetermined measurement period; filtering, when the mobile terminal exits the sleep/idle mode, the measured battery parameters and storing the filtered battery parameters; and acquiring state of charge of the mobile terminal in accordance with the stored battery parameters. According to the technical solution of the present invention, the battery power of the mobile terminal can be measured and the process of the battery power consumption can be calculated accurately.
摘要:
A method of connecting an NFC reader to a plurality of NFC devices, the plurality of NFC devices comprising at least one NFC-A device and at least one RF barcode, the method comprising the steps of: detecting and logging the active and sleep intervals of the RF barcode when an RF field is switched on; and synchronizing the transmission and reception of data to, and from, the or each NFC-A device such that transmission and reception of data to, and from, the or each NFC-A device occurs only when the or each RF barcode is in a sleep interval.
摘要:
An apparatus for calibrating a stereoscopic camera, the apparatus comprising: - a processing unit configured to support at least a first triangulation unit, a second triangulation unit and a Bundle Adjustment unit, with respect to at least one stereo-image of the stereoscopic camera, wherein the processing unit is further configured to determine a convergence criterion indicative of whether or not a camera calibration ground-truth has been found. A method, devices and a computer-readable storage medium are also claimed.
摘要:
An exemplary method of maintaining secure time in a computing device is disclosed in which one or more processors implements a Rich Execution Environment (REE), and a separate Trusted Execution Environment (TEE). The TEE maintains a real-time clock (RTC) that provides a RTC time to the REE. A RTC offset is stored in non-volatile memory, with the RTC offset indicating a difference between the RTC time and a protected reference (PR) time. Responsive to a request from the REE to read the RTC time, a current RTC time is returned to the REE. Responsive to a request from the REE to adjust the RTC time, the RTC time and the corresponding RTC offset are adjusted by a same amount, such that the PR time is not altered by the RTC adjustment. An exemplary computing device operable to implement the method is also disclosed.
