    Abstract: An optical mode converter for coupling between photonic integrated circuit (PIC) and optical fiber of different mode sizes is illustrated. The optical mode converter includes a waveguide assembly including a Single waveguide structure, a Multi-layer waveguide structure, and a Transitional waveguide structure. The Single waveguide structure includes a single waveguide. The dimension and propagation constant of a first end, of the single waveguide, is similar to a waveguide of a photonic integrated circuit (PIC). Furthermore, the Multi-layer waveguide structure included a multi-layer waveguide. Further, the Transitional waveguide structure is formed at a transitional structure. The Transitional waveguide structure allows transition of an optical mode between the Single waveguide structure and Multi-layer waveguide structure.

  • Publication number: 20190318720
    Abstract: A sound recognition system including time-dependent analog filtered feature extraction and sequencing. An analog front end (AFE) in the system receives input analog signals, such as signals representing an audio input to a microphone. Features in the input signal are extracted, by measuring such attributes as zero crossing events and total energy in filtered versions of the signal with different frequency characteristics at different times during the audio event. In one embodiment, a tunable analog filter is controlled to change its frequency characteristics at different times during the event. In another embodiment, multiple analog filters with different filter characteristics filter the input signal in parallel, and signal features are extracted from each filtered signal; a multiplexer selects the desired features at different times during the event.

    Abstract: In an aspect, a tensioner is provided for tensioning a belt on an engine, and includes a base mountable to a stationary member, and a first tensioner arm pivotably connected to the base. The first tensioner arm is biased in a first pivot direction. The tensioner includes a first bumper on one of the base and the first tensioner arm, which is engageable with a first travel limiter on the other of the base and the first tensioner arm to limit travel of the first tensioner arm in a second pivot direction, and a first pulley rotatably mounted to the first tensioner arm and positioned to engage a first section of the belt. The first bumper and the first travel limiter together have a selected first combined spring rate during engagement. The first combined spring rate increases progressively with compression between the first bumper and the first travel limiter.

  • Patent number: 10412485
    Abstract: A duty-cycled acoustic sensor saves power, for example, by operating for relatively short periods of time in a repetitive manner. A sensor bias current provides operating power to the sensor. An output analog signal from the sensor carries the information induced by the sensor upon the bias signal. Capacitive coupling is employed to remove direct DC voltage from the output analog signal to generate an analog input signal for acoustic analysis. A capacitor for capacitive coupling is pre-charged to reduce the charging time of the capacitor as the sensor is being powered up. After the capacitor is sufficiently precharged, acoustic analysis is performed on the analog input signal. The sensor is powered down by substantially blocking current flow through the sensor, which saves power. Results of the acoustic analysis can be used, for example, to control parameters of the duty-cycling of the acoustic sensor.
