Abstract: An energy saving method for an automobile is provided herein. The energy saving method includes: judging whether the automobile is stopped; starting a timer to measure and signal an end of a predetermined time interval by outputting an interrupt signal; and turning off an engine of the automobile in response to the interrupt signal. A related energy saving device is also provided.

Abstract: A mobile communication method is used for identifying a subscriber of a mobile communication device. The mobile communication method includes: sampling biometric information of the subscriber; generating an biometric analysis; generating digital signals according to the biometric analysis and an IMEI number; generating RF signals according to the digital signals and transmitting the RF signals; receiving the RF signals and transforming the RF signals to the digital signals; retrieving the biometric analysis and the IMEI number from the digital signals; comparing the biometric analysis and a user biometric profile; selecting a phone number according to the biometric analysis if the biometric analysis and the user biometric profile are the same; and transmitting the phone number to the mobile communication device based on the IMEI number. A mobile communication device and a mobile communication system are also provided.
