    Abstract: A flow meter ultrasonically measures fluid velocity in a pipe and ultrasonically transmits fluid flow data along the pipe. An ultrasonic transducer used for fluid velocity measurement may optionally also be used for communication of flow data, and optionally, the ultrasonic frequency for fluid velocity measurement may be the same as the ultrasonic frequency for communication of flow data.

    Abstract: Methods and apparatus for creating a physically unclonable function for SRAM are disclosed. An example method includes decreasing a supply voltage of a memory array to a first voltage level, the first voltage level being below a normal operating voltage associated with the memory array, reading a first value of a bit cell after the supply voltage has been at the first voltage level, and determining a function based on the first value of the bit cell and a second value, the second value stored in the bit cell when the memory array is operating at a voltage level above the first voltage level, the function to represent an identification of a circuit including the memory array.

    Abstract: Read-only (“RO”) data consisting of a physically unclonable function (“PUF”) pattern is written to a ferroelectric random-access memory (“FRAM”) memory array. The FRAM array is baked to imprint the PUF pattern with a selected average depth of imprint and a corresponding average read reliability. The average depth of imprint and corresponding average read reliability are determined during testing after baking. The PUF pattern as read after baking is compared to the PUF pattern as written prior to baking. Additional PUF pattern writing and baking cycles may be performed until the average depth of imprint and associated read reliability reach a first selected level. Integrated circuits determined to be over-imprinted by exceeding a second selected level may be rejected. The first and second levels of PUF pattern imprint are selected such as to produce FRAM arrays with a unique fingerprint for each individual FRAM array-containing integrated circuit.

    Abstract: A transceiver device combination includes a first ultrasound transducer and a processor chip including a central processing unit (CPU). A memory is coupled to the CPU including stored ultrasound communications software for rendering the processor chip a target device for an ultrasound probe driven via a host computing device having a second ultrasound transducer for together performing ultrasonic debugging of the processor chip. The transceiver device combination includes (i) a transmit path including an ultrasound driver having an input driven by an output of the CPU, where an output of the ultrasound driver is coupled to drive an input of the first ultrasound transducer to transmit ultrasound signals and (ii) a receive path including analog signal processing circuitry that couples an output of the first ultrasound transducer responsive to received ultrasound signals from the ultrasound probe to an input of the CPU.
