The present disclosure provides a control method of an electronic device. The electronic device includes a touch display screen and a proximity sensor. The proximity sensor is disposed under a display area of the touch display screen. The control method includes: keeping the proximity sensor deactivated; determining whether the touch display screen is shielded according to a signal output by the touch display screen; controlling the touch display screen to enter a black-out state and activating the proximity sensor when the touch display screen is shielded; and controlling a display state of the touch display screen according to detection data of the proximity sensor. The present disclosure also provides a control device, an electronic device, a storage medium and a computer device.

Control method, control device, electronic device and storage medium

Systems, devices, and methods allow real-time communication between an access device and at least one communication device. The access device is configured to: determine whether a distance between a communication device and the access device reaches a predetermined access distance for accessing a network; if so, allow the communication device to gain access to the network via the access device to achieve real-time communication between the communication device and the network.

Real-time communication system, device, and method

The present invention relates to a communication system and a communication method. The communication system includes a micro IC card, a radio frequency (RF) card sleeve and a multi-frequency card reader. The micro IC card is used to communicate with the RF card sleeve through a contact interface. The multi-frequency card reader is used to perform an RF communication with the RF card sleeve. The communication method includes exchanging data with a micro IC card through an RF channel; and the micro IC card sleeve exchanges data with the micro IC card by a contact communication. The communication system and method provide operators a working environment to adapt cards with different frequencies. Thus, telecommunication operators and financial service providers are able to independently issue their own cards, which lowers difficulties of promoting mobile payment services, and aids to boost the popularization and applications of the mobile payment services.

Communication system and communication method

A radio frequency communication system, method, and device operate in the VHF, UHF, or SHF range, where a controller controls the radio-frequency communication range provided by the VHF, UHF, or SHF radiation.

System, method, and device for radio frequency communication

A method and RF SIM card communication system using a tag recognition to control the RF communication range, a tag for providing data information is installed on a mobile communication terminal equipped with an RF SIM card, a tag reader module for reading out and transmitting the data information is installed on an RF card reader device, setting a card reading condition for the card reader device as: under the condition that the tag reader module reads out the tag data information, the RF card reader module, based on the data information of the tag, establishes wireless communication link with and transfers data to the RF SIM card in the mobile terminal. The present invention is not affected by the shielding effect of the mobile communication terminal, thereby avoids the cumbersome calibration process for the RF SIM card transceiver power and receiver sensitivity in existing technologies, this both brings convenience to the users, and further facilitates of widespread use of RF SIM cards.

Method and communication system for controlling communication distance of RF SIM card with the aid of tag identification

A radio frequency (RF) device includes an RF transceiver, an RF antenna, and a magnetic signal detector. The RF is selected to be in the very high frequency (VHF), ultrahigh frequency (UHF), or super high frequency (SHF) bands such that the shielding effect is reduced and the RF device can be configured as a SIM card disposed inside a cellular phone with an increased RF communication range. The magnetic signal detector is used to sense a magnetic field signal from an RF reader, which includes an RF transceiver, an RF antenna, and a magnetic signal transmitter. The longer communication range afforded by the VHF, UHF, or SHF bands is reduced by the sensing of the magnetic field, thereby providing a communication range control, while the RF device and the RF reader exchange information through the RF channel with improved security as a result of the range control.

RF SIM card, card reader, and communication method

A radio frequency (RF) IC card device with very high frequency comprises an IC device (), a radio frequency interface device (), an RF antenna (), an IC card interface () and an RF interface (). Particularly, said RF interface device () and the RF interface () operate in a frequency band of UHF (ultra high frequency) or SHF (super high frequency); said RF antenna () is directly integrated on an IC card (); the RF IC card device with very high frequency exchanges data with other RF devices via the RF interface ().
