Abstract: A system configured to detect a tap event on a surface of a device using microphone audio data and motion data. Instead of using a physical sensor to detect the tap event, the device detects a tap event based on a power level difference between two or more microphones. When a power ratio exceeds a threshold, the device may detect a tap event and perform an action, such as delaying or ending an alarm. To reduce false positives caused by wind or loud noises close to the microphones, the device may confirm a tap event using motion data that indicates actual movement of the device. In some examples, the device may detect the tap event using a neural network processing the microphone data and the motion data. In addition, the device may embed the motion data within the microphone data using unused bits of the microphone data.

The apparatus includes a mid-infrared region laser that generates a first light beam, and a stage adapted to carry a specimen to be scanned. An optical assembly focuses the first light beam to a point on the specimen. A first light detector measures a first intensity of light leaving the point on the specimen.

The image can be based on reflected or transmitted light. The maximum size of the imaged area is determined by a scanning assembly that moves in a first direction relative to the stage, the stage moving in a direction orthogonal to the first direction.

Abstract: Sensors in a facility obtain sensor data about a user's interaction with a fixture, such as a shelf. The sensor data may include images such as obtained from overhead cameras, weight changes from weight sensors at the shelf, and so forth. Based on the sensor data, one or more hypotheses that indicate the items and quantity may be determined and assessed.

A hypothesis having a greatest confidence value may be deemed to be representative of the user's interaction, and interaction data indicative of the item and quantity may be stored.
