  • Radar liquid level measuring apparatus and radar liquid level measuring method
    Patent number: 9823110
    Abstract: A radar liquid level measuring apparatus (10) includes a first oscillation module (102), a second oscillation module (104), a frequency comparator (106) and a control module (107). The first oscillation module (102) has a first oscillation frequency. The first oscillation module (102) generates a first pulse signal (10202). The second oscillation module (104) has a second oscillation frequency. The second oscillation module (104) generates a second pulse signal (10402). The frequency comparator (106) converts the first pulse signal (10202) and the second pulse signal (10402) into an adjusted signal (10602). The control module (107) compares the adjusted signal (10602) with an expectation value (10818) to obtain a comparative result signal. According to the comparative result signal, the control module (107) adjusts the second oscillation frequency, so that the second oscillation frequency and the first oscillation frequency have a constant frequency difference.

  • Methods for processing and addressing data between volatile memory and non-volatile memory in an electronic apparatus
    Patent number: 9037773
    Abstract: An electronic apparatus is disclosed. The electronic apparatus comprises a random access memory (RAM), a read-only memory (ROM) and a processing unit. The RAM stores a call transfer table, wherein the call transfer table comprising at least one transferred address in the RAM. The ROM stores at least one code to call one address of the call transfer table. The processing unit executes the code in the ROM and reads the transfer table accordingly, then transfers to run the data in the transferred address of the RAM.
