Described herein are a device and a method for recognizing and monitoring a fluid in a system and/or in surroundings of the system via a computer vision application, the device including at least the following components: at least one luminescent dye, each luminescent dye having a dye specific reflectance and luminescence spectral pattern and being configured to be added to the fluid, a light source which is composed of at least two illuminants and which is configured to illuminate a scene which includes the system and/or the surroundings of the system, by switching between the at least two illuminants, where at least one of the two illuminants is based on at least one solid-state system, a sensor which is configured to measure radiance data of the scene when the scene is illuminated by the light source, and a data processing unit.

Described herein are a device and a method for forming at least one ground truth database for an object recognition system and for keeping the at least one ground truth database current. The device comprises includes at least the following components: a data storage unit configured to store color space positions and/or reflectance spectra and/or luminescence spectra of different objects; and a processor programmed for communication with the data storage unit and with the object recognition system.

Systems and methods for ossification center detection (OCD) and bone age assessment (BAA) may be provided. The method may include obtaining a bone age image of a subject. The method may include generating a normalized bone age image by preprocessing the bone age image. The method may include determining, based on the normalized bone age image, positions of a plurality of ossification centers using an ossification center localization (OCL) model. The method may include estimating, based on the normalized bone age image and information related to the positions of the plurality of ossification centers, a bone age of the subject using a bone age assessment (BAA) model.

A method for tracking a maximum temperature point includes acquiring a first pair of coordinates of a maximum temperature point in a current frame of image sensed by an infrared camera, determining a rotation angle of a gimbal equipped with the infrared camera according to the first pair of coordinates of the maximum temperature point in the current frame of image and a pair of coordinates of a target position of the maximum temperature point in a subsequent frame of image, and controlling the gimbal to rotate according to the rotation angle, so as to adjust the maximum temperature point in the subsequent frame of image captured by the infrared camera to be located at the target position.

A virtual reality display device, a display device, and a calculation method of a line-of-sight angle are provided. The virtual reality display device includes: a display screen configured to display a picture to a user, at least one infrared light source, and an infrared camera; and the infrared camera is on a side of the display screen away from an eye of the user, and is configured to acquire an eye image of the eye of the user that is illuminated by the at least one infrared light source.

A monitoring system and method for a tool of working equipment, preferably a ground engaging tool comprising wear members such as an excavator bucket, the system/method including one or more sensors mounted on the working equipment and directed towards the tool and a processor configured to: receive data relating to the tool from the one or more sensors, generate a three dimensional representation of at least a portion of the tool using the received data, compare the generated three dimensional representation with a previously generated three dimensional representation, and identify one or more of wear and loss of at least a portion of the tool, preferably a wear member portion, using the comparison of the generated three dimensional representation with the previously generated three dimensional representation.

This document describes techniques and systems that enable a smartphone providing radar-based proxemic context. The techniques and systems use a radar field to accurately determine a user's location and/or physical orientation with respect to an electronic device, such as a smartphone. The radar field also enables the device to receive 3D gestures from the user to interact with the device. The techniques allow the device to provide functionality based on the user's presence and/or orientation, and to appropriately adjust the timing, content, and format of the device's interactions with the user.

A vehicle lamp system mounted on a vehicle includes an in-vehicle sensor includes an IR light source, a scanning unit, an infrared camera, a region setting unit for comparing information acquired from the in-vehicle sensor and information acquired by the infrared camera and setting a dimming area and/or an emphasis area, and a lamp control unit for controlling an applied power amount and turning on and off of the IR light source such that a specific region is irradiated with the infrared rays emitted from the IR light source based on output of the region setting unit.
