    摘要: A hand-held sized imaging instrument identifies molecules with high selectivity and in complex mixtures. The instrument uses inelastic scattering and scattering intensities from with machine learning algorithms based on convolutional neural networks (CNN's) to identify the presence of a specified chemical or combination of chemicals. A laser is housed within the instrument to initiate a material response of a sample using laser light of a specified wavelength. The instrument uses an image sensor to capture visible images with inelastic scattering information. The CNN is able to classify the image to determine whether the specified chemical or combination of chemicals is present in the sample. The instrument is inexpensive, portable, easy to use by anyone (nonchemist, nonprofessional), and safe (laser is completely housed). The instrument can be used efficiently and easily for quality control, security, and other applications to reliably detect the presence of specified substances.

    摘要: Provided are display apparatuses. A display apparatus includes: a display, and a controller connected to the display, the controller is configured to: display a first interface on the display; in response to no operation for the first interface reaching a first time threshold, create a screensaver display interface by a screensaver application in the display apparatus, where the screensaver display interface is transparent with respect to the first interface; present the screensaver display interface on the display without blocking the first interface presented on the display; create a screensaver view comprising a plurality of screensaver interfaces by the screensaver application; and present the first screensaver interface in the screensaver view on the screensaver display interface to block the first interface, where the first access entry and the first presentation material are visible for a user and the first access entry is available for selection by the user.

    摘要: An exemplary method and system is disclosed that facilitates a readily-re-deployable and self-enclosed geofencing and proximity-based intrusion sensing and alerting system in a roadway or construction work zone. The sensing and alerting system is configured in the form factor of a safety cone, barricade or drum to sense and uses acoustic-echoes or LiDAR-based sensing to detect intruders that are in proximity to the sensing and alerting system to generate a siren or loud audible alert, as well as flashing lights, to warn workers of such intrusion.
