Voice interaction development tool
A voice interaction development tool is described. Initially, user input associating voice interaction data with a visual object is received via a user interface. The voice interaction data, for example, may include voice commands and corresponding output content. Subsequently, a request is received from a voice assistant platform, due to initiation via a voice command to the voice assistant platform. In real-time (e.g., as the user speaks the voice command) a visual object corresponding to the spoken voice command is graphically indicated, e.g., a flow diagram element corresponding to the voice command is emphasized. In real-time as output content corresponding to the voice command is output by a voice assistant device, the user interface provides a graphical indication of the visual object associated with the output content. In this way, the described system provides graphical feedback for testing voice interactions being developed. |

Common pool management
Disclosed in some examples are methods, systems, machine-readable mediums, and NAND devices which create logical partitions when requested to create a physical partition. The controller on the NAND mimics the creation of the physical partition to the host device that requested the physical partition. Thus, the host device sees the logical partition as a physical partition. Despite this, the NAND does not incur the memory storage expense of creating a separate partition, and additionally the NAND can borrow cells for overprovisioning from another partition. In these examples, a host device operating system believes that a physical partition has been created, but the NAND manages the memory as a contiguous pool of resources. Thus, a logical partition is created at the NAND memory controller level—as opposed to at the operating system level. |

Ultra-responsive phase shifters for depletion mode silicon modulators
A novel phase shifter design for carrier depletion based silicon modulators, based on an experimentally validated model, is described. It is believed that the heretofore neglected effect of incomplete ionization will have a significant impact on ultra-responsive phase shifters. A low VπL product of 0.3 V·cm associated with a low propagation loss of 20 dB/cm is expected to be observed. The phase shifter is based on overlapping implantation steps, where the doses and energies are carefully chosen to utilize counter-doping to produce an S-shaped junction. This junction has a particularly attractive VπL figure of merit, while simultaneously achieving attractively low capacitance and optical loss. This improvement will enable significantly smaller Mach-Zehnder modulators to be constructed that nonetheless would have low drive voltages, with substantial decreases in insertion loss. The described fabrication process is of minimal complexity; in particular, no high-resolution lithographic step is required. |

Devices and methods for quartz enhanced photoacoustic spectroscopy
In quartz-enhanced photoacoustic spectroscopy (QEPAS), an analyte (typically in gas phase) generates a pressure wave in response to incident laser light. A quartz tuning fork (QTF) resonant at the frequency of the pressure wave transduces the pressure wave into an electrical signal. Pulsing the laser briefly reduces the amount of thermal chirp and increases the fraction of time that the laser emits at the wavelength(s) of interest. This increases the measurement efficiency. Pulsing the incident laser light with bursts of short pulses at the QTF resonant frequency increases signal strength. Exciting the sample with a two pulses at different laser wavelengths, separated by a half QTF period yields signal and background acoustic waves that partially cancel when integrated by the QTF, producing a differential measurement. Pulsing the incident laser light at a frequency faster than the gas response cut off frequency can improve the noise performance of a QEPAS measurement. |

Method for magnetic flux compensation in a directional solidification furnace utilizing a stationary secondary coil
A process for directional solidification of a cast part comprises energizing a primary inductive coil coupled to a chamber having a mold containing a material; energizing a primary inductive coil within the chamber to heat the mold via radiation from a susceptor, wherein the resultant electromagnetic field partially leaks through the susceptor coupled to the chamber between the primary inductive coil and the mold; determining a magnetic flux profile of the electromagnetic field; sensing a magnetic flux leakage past the susceptor within the chamber; generating a control field from a secondary compensation coil coupled to the chamber, wherein the control field controls the magnetic flux experienced by the cast part; and casting the material within the mold under the controlled degree of flux leakage. |
