An electronic device includes a touch screen. When the electronic device wakes up and works in a locked state, a notification interface including a predetermined unlocking area is displayed on the touch screen. A user pattern formed by at least two fingers of a user located within the predetermined unlocking area is detected. The electronic device is unlocked if the user pattern matches a predetermined unlocking pattern.

Electronic device and unlocking method thereof

An electronic device includes a sound collecting unit and a processor. The processor determine whether continuous sound signals collected by the sound collecting unit includes a first alternating portion, a direct portion, and a second alternating portion in sequence. The processor further determines whether a first duration of the direction signals portion falls within a first preset time range, and determines whether a second duration of each of the first alternating portion and the second alternating portion falls within a second preset time range. The processor then triggers a function of the electronic device when the first duration falls within the first preset time range, and the second duration falls within the second preset time range. A related method is also disclosed.

Electronic device and method for triggering function of electronic device

A method for protecting a touch-sensitive device includes: switching the touch-sensitive device from a normal mode to a protection mode when a preset operation is exerted; determining whether a touch operation is exerted after the touch-sensitive device enters the protection mode, and further determine whether a duration of the touch-sensitive device in the protection mode exceeds a preset time interval; comparing a touch size of the touch operation with a preset size when the duration of the touch-sensitive device in the protection mode exceeds the preset time interval; and generating an alarm signal when the touch size is less than the preset size. A related touch-sensitive device is also provided.

Touch-sensitive device with protection function and protection method

A battery simulation circuit simulates a rechargeable battery. The battery simulation circuit includes an integrated amplifier, a voltage adjustment unit, a current limitation unit, and a feedback unit. The voltage adjustment unit provides a reference voltage for the integrated amplifier; the current limitation unit provides a reference current for the integrated amplifier and the feedback unit provides a negative feedback signal for the integrated amplifier to control the integrated amplifier working in a linear state. The integrated amplifier outputs an output signal according to the reference voltage and the reference current; the battery simulation circuit supplies power for an electronic device. When the output terminal is connected to a DC power source and a voltage of the DC power source is greater than the output voltage of the output terminal, the battery simulation circuit simulates a battery being recharged by the DC power source via the output terminal.

A message transmitting method of a communication device, the communication devices stores an information matching table. The information matching table includes a telephone directory column recording a plurality of predetermined telephone numbers and a message column recording a plurality of predetermined messages in advance. When an incoming call is received, whether a phone number of the incoming call is recorded in the telephone directory column of the matching information table is determined. If the phone number of the incoming call is recorded in the telephone directory column, a prompt message stored in the information matching table is determined as a prompt message to prompt a user according to the phone number of the incoming call.

Communication device and message transmitting method

An anti-eavesdropping communication system and method are adapted to be applied in a mobile phone. The mobile phone defines a normal call mode and an anti-eavesdropping call mode. When a user of the mobile phone has a phone conversation using an earphone in the anti-eavesdropping call mode, the system plays a preset audio file which is a recording of the voice of the user saying unimportant things. From the position of a bystander, the recording of the voice of the user interferes with the clarity of what the user is actually saying, and prevents people beside the user overhearing or eavesdropping on the actual conversation which is taking place.

Anti-eavesdropping communication system and method

A resistance-measuring circuit includes a controller for outputting a PWM signal and further for adjusting the duty cycle of the PWM signal, and a sampling circuit for processing the PWM signal and transmitting the processed PWM signal to the sensor. The sampling circuit samples the signal outputted from the sensor to generate a sampled signal with the voltage thereof changing according to any change in the duty cycle of the PWM signal, and further transmits the sampled signal to the controller. The controller obtains the real-time duty cycle of the PWM signal when the voltage of the sampled signal reaches a threshold voltage, and further calculates the exact resistance of the sensor according to the obtained real-time duty cycle of the PWM signal and the threshold voltage. An electronic device with the resistance-measuring circuit is also provided.
