Abstract: An interactive alerting method for an electronic apparatus is disclosed. The method receives and displays an alerting message once an abnormal situation occurs to the electronic apparatus. The method provides interactive questions to a user according to the type of the abnormal situation. Next, the method receives replies from the user aimed at the interactive questions, and obtains one or more causes of the abnormal situation according to the replies. Eventually, the method displays the obtained causes on a mobile device of the user. The cause of an abnormal situation occurs to an electronic apparatus is obtained via the replies aimed at interactive questions made by a user, which effectively increases the accuracy of the cause of the abnormal situation offered to the user.

Abstract: A system for managing real-time work information of a motor fitting provides a sensor set at the motor fitting to transmit the real-time work information to a processing module. A processing unit of the processing module sends type information and a real-time work parameter according to the real-time work information. When a detection unit determines the real-time work parameter is fallen outside a normal work parameter according to a lookup table stored in a database and the type information, the detection unit generates an abnormal-notification signal for transmission. When an application procedure of the application-processing unit is triggered, the application-processing unit activates a play unit to play the normal work parameter, and further the activated play unit plays notification information upon receiving the abnormal-notification signal.

Abstract: A gain and frequency compensated barrier circuit is disclosed for use with a telephone transmission line having variable loop lengths. A DC component of the input signal is provided to the input side of the barrier circuit. Loop length losses, as well as barrier gain variations, are adjusted on the output side of the circuit by comparing a barrier DC voltage level with a DC reference level and adjusting the AC gain in accordance therewith. Frequency response, which is also a function of loop length, is corrected by using the DC input voltage to generate an effective loop length dependent capacitor for further controlling the output signal level. An optocoupled circuit is disclosed for use in one embodiment of the disclosure.

Abstract: A remote gain controlled optocoupled device is disclosed utilizing a DC reference voltage in the output section to compensate for variations in the optocoupling characteristics of the circuit. The DC voltage level output of the photodetector, which is a function of the light transfer characteristics of the circuit, is compared to a remotely controlled reference DC level. The output AC signal level, which substantially tracks the DC voltage output, is gain adjusted under control of the compared DC voltage levels.

Abstract: There is disclosed a protective coupler circuit of the circuit breaker type having a relay contact inserted in the communication line between the key telephone station and the central office in order to protect the central office line from hazardous voltages. A longitudinal unbalance detector is coupled with a metallic high voltage detector to control the relay operation. Circuitry is provided to operate in conjunction with the ring detection circuitry of the key telephone unit to insure proper circuit operation when ringing potential is present on the communication line even though that potential is over the threshold level of the hazardous voltage protector.

Abstract: In order to reduce the signal loss in a telephone line switching and conferencing system there is interposed between each line and the switching matrix a monobus port circuit arranged to convert a transmitted telephone signal into an equivalent current source. An opto-coupled hybrid replaces the port circuit transformer and serves to provide the desired voltage to current conversion. The currents from several monobus circuits are added in a bus resistor before distribution back to the individual monobus circuits as a voltage where the original signal is subtracted from the bus signal. The resultant signal is transmitted to the telephone receiver via the opto-coupled hybrid. When the switching matrix crosspoint resistance is negligible, the component of the bus voltage measured at the current source output which results from current generated from each port circuit is equal and opposite in magnitude to the voltage generated in the port circuit.

Abstract: A plurality of idle paths through a multistage switching network which are capable of establishing a connection between a particular line and a particular trunk are identified. Repeated selection of paths identified as idle, but actually out-of-service, is avoided by selecting successively different ones of the identified idle paths in a pseudorandom manner to complete the connection between the line and the trunk. The pseudorandom path selection is accomplished in response to predetermined portions of a pseudorandom pattern of binary bits.

The currents from several monobus circuits are added in a bus resistor before distribution back to the individual monobus circuit where the original signal is subtracted from the bus signal. The resultant signal is transmitted to the telephone receiver. When the switching matrix crosspoint resistance is negligible, the component of the bus voltage measured at the current source output which results from current generated from each line is equal and opposite in magnitude to the voltage generated in the line. In any given line these voltages cancel each other, thereby eliminating the feedback signal.
