An apparatus for reminding a user of overlong access to a webpage is provided. The apparatus typically includes a communicating module, a timing module, and a control module. The communicating module transmits to a network server a request by the user to be logged into the network server, and accesses a webpage of the network server. The timing module times an elapse time of the webpage being not operated by the user. The control module sends a reminder to the user to operate the webpage when the elapse time has reached a reminding time. The control module stores information which was edited on the webpage and webpage content if the webpage is not operated again within a predetermined period, and transmit a signal containing an instruction for the network server to log out the user. A related method is also provided.

An overvoltage and overcurrent protection circuit includes a connection jack, an overvoltage protection switch connected to the connection jack, an overcurrent protection switch, a voltage reference module, an overvoltage and overcurrent detection module, a comparing module, and a current control module. The overcurrent protection switch is connected to the overvoltage protection switch in serials, and further connected to a load. The voltage reference module is to output a reference voltage. The overvoltage and overcurrent detection module is to detect the voltage of the load and the current of the path. The comparing module is to compare the voltage of the load with the reference voltage, when greater, turns off the overvoltage protection switch, when not greater, turns on the overvoltage protection switch. The current control module is to turn off the overcurrent protection switch if greater than the preset value, and turn on the overcurrent protection switch if not greater.

An interactive voice recognition electronic device converts a received voice signal to a text, and searches a voice databases to find a matched voice text of the converted text. The matched voice text is taken as a recognized voice text of the voice signal if the matched voice text exists in the voice database. The electronic device obtains a predetermined number of similar voice texts if no matched voice text exists in the voice database. The electronic device converts the predetermined number of similar voice texts to the voice signals, outputs the converted voice signals in turn, and selects one of the similar voice texts as the recognized voice text according to the selection of the user. The electronic device obtains the associated answer text of the recognized voice text in the voice database and converts the answer text to voice signals.

An assay device capable of assaying purity of a substance in an object includes a memory, an emitter, a receiver, a processing unit, and a display device. The memory stores names and standard densities of a number of substances. The emitter emits rays at the object. The receiver receives the rays reflected by the object. The processing unit calculates density of the object according to intensity of the emitted rays and intensity of the reflected rays. The processing unit further calculates purity of a selected substance in the object according to the density of the object and standard density of the selected substance stored in the memory, and outputs the calculated purity to the display device.

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.
