Narrowband direction of arrival for full band beamformer
A system and method for improving the performance of a hands-free voice user interface system while minimizing the computational complexity without sacrificing performance. Specifically, when estimating the location of the talker for the purpose of steering a directional beam in the direction of the active talker. A hands-free voice user interface system requires a clean signal to be streamed to the cloud for recognition. One way to improve the speech signal is to estimate where the talker is and steer a beam in the direction of the active talker. To locate the talker to a localized position, a direction of arrival estimator (DOA) algorithm is used. DoA generally requires noise and echo free signal for optimal estimation, but it is computationally expensive to run audio pre-processing such as an acoustic echo cancellation for each microphone in microphone array. To reduce computational complexity, the system and method extract certain range of frequency and operate pre-processing only on the selected frequency. By properly selecting the frequency range, it does not degrade DoA accuracy while significantly reducing computational complexity. |

Noise model-based converter with signal steps based on uncertainty
Embodiments of the present invention are directed to a noise-model based sensor converter configured to map a sensor measurement output to discrete, nonlinear steps of constant uncertainty. In a non-limiting embodiment of the invention, the sensor converter receives an output signal from a sensor. The output signal can include a measurement. The sensor converter can also receive a noise model. The output signal is mapped to a discrete set of steps based on the noise model. The discrete set of steps are nonlinearly spaced to provide constant uncertainty between adjacent steps. The sensor converter generates an output based on the discrete set of steps. |

Projection device
Light emitted from laser light source is divided by prism into two light flux and light flux corresponding to light emitted from slope and slope. Light flux and light flux are diffused by diffusion plate and diffusion plate to become light flux and light flux. By overlapping light flux and light flux, a radiation distribution with a wide angle and high light intensity can be obtained. |

TIC environmental event sensor
The TIC environmental event sensor is a nickel-sized, ultra-thin circuit assembly, containing an extremely compact array of both environmental sensors and physical sensors, along with local and wireless access to all the sensor data, including BTLE & LoRa, as well as an electronic ink display for limited field access to sensor events in real time. The TIC is designed to capture changes in the sensor data in real time, and then log it for future examination. The most recent change will remain on the device's display. The changes can then be transmitted to a smart phone or tablet via BTLE, networked as an asset via LoRa, or locally scrolled at the device. The TIC is Ideal for tracking any variations in the surrounding conditions of an asset's travel, storage or use. |
