Abstract: A transcription of audio speech included in electronic content associated with a meeting is created by an ASR model trained on speech-to-text data. The transcription is post-processed by modifying text included in the transcription, for example, by modifying punctuation, grammar, or formatting introduced by the ASR model and by changing or omitting one or more words that were included in both the audio speech and the transcription. After the transcription is post-processed, output based on the post-processed transcription is generated in the form of a meeting summary and/or template.

Abstract: The invention discloses a powder leakage monitoring device and a powder leakage monitoring method. The powder leakage monitoring device comprises light field camera, 3D PTZ (3-Dimensional Pan/Tilt/Zoom) and computer. Wherein, the light field camera records original light field images of monitored area; the 3D PTZ under the light field camera adjusts the shooting angle of the light field camera when it rotates according to the set direction; and the computer respectively connects to the light field camera and the 3D PTZ, which generates refocused images corresponding to the original light field images, and determines the spatial coordinates of the powder leakage point and the hazard range of the powder leakage in the monitored area according to the refocused images and the shooting angle. Therefore, the range and accuracy of powder leakage monitoring are both increased by using this invention.

Abstract: A lock-on switch system for hand drill includes a switch disposed in a switch housing for controlling the operation of the drill, a trigger which is adapted to be movable between a home position where the trigger turns off the switch and a pushed-in position where the trigger turns on the switch, a pivotable locking bar having a front end adapted to be engaged with the trigger for locking the trigger in the pushed-in position, a slidable actuator adapted for pushing the locking bar into engagement with the trigger, and biasing means adapted for applying a force on the locking bar in a direction of disengaging the locking bar from the trigger.
