  • SYSTEM FOR PUMPING AND METERING A FLUID FOR A TURBINE ENGINE AND METHOD FOR CONTROLLING SUCH A SYSTEM
    Publication number: 20240159192
    Abstract: A system for pumping and metering a fluid for a turbine engine, which system includes at least one pump for the fluid and an electronic computer configured to determine the flow rate of the fluid to be delivered to the turbine engine, the pumping and metering system being wherein it further includes a first electric motor and a second electric motor, which are each configured to drive the at least one pump, and in that the electronic computer includes a first control loop for controlling at least the first electric motor and a second control loop for controlling at least the second electric motor.

  • Bulk acoustic resonator devices and processes for fabricating bulk acoustic resonator devices
    Patent number: 10181835
    Abstract: In a bulk acoustic resonator device, at least one additional metal feature is formed on a top surface of the bottom electrode at a location at which the bottom electrode electrical contact will subsequently be formed, thereby thickening the metal at the location below where the piezoelectric material layer will be etched to form the opening for the bottom electrode electrical contact. Consequently, even though some of the metal of the additional metal feature and/or of the bottom electrode will be removed during the process of etching the opening in the piezoelectric material layer, the bottom electrode will always retain sufficient thickness after the piezoelectric material layer is etched.
