Abstract:
A charger and a charging system are provided. The charger includes: a rectifier, a transformer, a first diode, a capacitor, a voltage sampling feedback unit, a pulse width modulation (PWM) controller, a battery voltage feedback unit and a semiconductor switching component, where the battery voltage feedback unit is added in the charger to detect battery voltage of a terminal, and the detected battery voltage of the terminal is fed back to a voltage sampling feedback unit inside the charger, so that the voltage sampling feedback unit can adjust an output voltage of the charger in real time according to an actual battery voltage of the terminal, and therefore, the output voltage of the charger gradually rises along with an increase of the battery voltage of the terminal, thereby effectively reducing energy consumption of the charger and achieving a purpose of energy saving.
Abstract:
A target detection method and apparatus based on online training. According to this method, an Nth frame of image is obtained; target detection and/or target tracking is performed on the Nth frame of image to obtain at least one Nth target area; and then, online training is performed on a training detection unit by using an (N−1)th target area, where the training detection unit stores all target areas that are detected in a first frame of image to an (N−1)th frame of image, so that online parallel processing on a detected target and the training detection unit is implemented, and multiple target samples are obtained according a user requirement; therefore, a target diversification requirement of an intelligent terminal user is satisfied, and further, a relatively accurate target area can be obtained according to a current user requirement.
Abstract:
Embodiments of the present invention provide a data transmission method, a base station, and a user equipment. The data transmission method includes: determining, by a base station, a modulation and coding level and a time-frequency resource, and determining, in a first or second modulation and transport block size index table, a TBS index and a modulation mode, where a second TBS index is not smaller than a first TBS index; and sending service data and a system scheduling control signal to a user equipment by adopting the selected TBS. In this way, the base station can select a larger TBS to achieve a higher coding rate and increase a system throughput.
Abstract:
In embodiments of the present invention, first user equipment acquires reference time, a first timing advance, and a data frame configuration, where the first timing advance represents a timing advance for the first user equipment to receive a first receiving subframe that is in the data frame configuration, and the first receiving subframe is sent by second user equipment; and the first user equipment determines, according to the reference time, the first timing advance, and the data frame configuration, time for receiving the first receiving subframe. Therefore, time when first UE receives a first receiving subframe sent by second UE is adjusted by using a first timing advance, so that the first UE has more accurate timing of a data frame, and interference among symbols can be avoided.
Abstract:
The embodiments of the present invention provide a method and an electronic apparatus for realizing virtual handwriting input. The method for realizing virtual handwriting input includes: obtaining, by an electronic apparatus, position coordinates of a handwriting apparatus in a virtual handwriting area through monitoring in a real-time manner, where the virtual handwriting area is an area in which a distance-measuring detector in the electronic apparatus may perform effective distance measurement; obtaining a track formed by the position coordinates, and obtaining a handwriting track of an entire handwriting input process when it is detected that the current handwriting input ends; and identifying a character corresponding to the obtained handwriting track and displaying the identified character. With the embodiments of the present invention, handwriting input may be realized simply and conveniently, and handwriting input may be realized and may be implemented with a low cost.
Abstract:
A web application security access method, including periodically detecting, by an application store server, if the locally stored source code is inconsistent with the source code that is corresponding to the web application and that is in the web server, adding an exception identifier to a version parameter stored on the application store server; receiving, by the application store server, an access request that is for accessing the web application and that is sent by a user by using a client, where the access request includes a user version parameter of source code corresponding to the web application installed on the client; and if detecting that the exception identifier exists in the version parameter, returning, by the application store server to the client, prompt information used to indicate to the user that there is a security risk in accessing the web application.
Abstract:
The present invention discloses a method, an apparatus, and a terminal for answering a call and relates to the field of terminal technologies. The method includes, after a call is received from a calling party, answering the call by using an automatic call answering function of a terminal, and talking with the calling party. If an instruction is received from an owner in the process of talking with the calling party, an operation is performed according to the instruction of the owner. If no instruction is received from an owner in the process of talking with the calling party, an emergency level of the call according to call content is determined, and an operation is performed according to the determined emergency level.
Abstract:
A wireless communications component that supports a first radio access technology (RAT) and a second RAT. After the wireless communications component establishes a connection with a second RAT network, the wireless communications component receives a first message sent by the second RAT network. The first message includes content that is used to query a second RAT capability of the wireless communications component. The wireless communications component sends a second message to the second RAT network. The second message is used to indicate the second RAT capability of the wireless communications component and indicate that the wireless communications component does not support the first RAT. Because the wireless communications component reports to the second RAT network that the wireless communications component does not support the first RAT, the second RAT network does not instruct the wireless communications component to be changed to the first RAT.
Abstract:
Embodiments of the present invention disclose an information search method and apparatus, where the method includes: acquiring a query keyword input by a user and a bookmark website address; acquiring a target bookmark website address according to the query keyword and the bookmark website address, where a page to which the target bookmark website address points includes the query keyword; and displaying a page label item corresponding to the target bookmark website address. By using the present invention, a website address that is actually required by a user can be more comprehensively and accurately found, so as to improve query efficiency and accuracy.
