A system includes: a first camera configured to capture first images of a driver on a driver's seat within a passenger cabin of the vehicle; a second camera configured to capture second images in front of the vehicle; a driver module configured to determine a driver and a present rank of the driver; a module configured to detect a condition based on at least one of (a) a first image, (b) a second image, and (c) a parameter measured by a sensor; a reinforcement module configured to: display the present rank within the passenger cabin; generate an output within the passenger cabin in response to the detection of the condition; when no conditions are detected, increment a rank period of the driver; selectively increase the present rank of the driver; and generate an alert within the passenger cabin in response to the increasing of the present rank.

A computer implemented method for detecting whether a seat belt is used in a vehicle comprises the following steps carried out by computer hardware components: acquiring an image of an interior of the vehicle; determining a plurality of sub-images based on the image; detecting, for at least one of the sub-images, whether a portion of the seat belt is present in the respective sub-image; and determining whether the seat belt is used based on the detecting.

Disclosed are techniques and apparatuses for seat belt status detection in a vehicle. In an aspect, a method includes the operations of: obtaining first infrared (IR) images and second visible light images of a seat belt region where a seat belt is expected to be visible when it is worn by a person in the vehicle; transmitting the first images to a first classifier and the second image to a second classifier; determining a first estimate of probability and a second estimate of probability that the seat belt is correctly worn, from the first and second classifiers; combining the two estimates of probability, using respective scores attributed to the first and second images, each score being indicative of the trustworthiness of the corresponding image to detect a seat belt status, to determine a combined probability; and comparing the combined probability to a predetermined threshold to determine a seat belt status.

A vehicle includes a door sensor configured to detect opening and closing of a door; a radar provided in the vehicle and configured to acquire radar data regarding an object in the vehicle; a seatbelt sensor configured to detect a state of a seat belt provided on each seat of the vehicle; a seatbelt indicator configured to provide a notification regarding fastening of the seat belt; and a controller configured to control the radar in response to the opening and the closing of the door, perform a first check regarding the state of the seatbelt, check an occupancy and an occupied position of the object based on the radar data, identify a type of the object in the vehicle based on the radar data, and determine an operating state of the seatbelt indicator based on the type of the object and the occupied position of the object.

A mechanism for restraining a passenger restrained in a restraint system of an amusement ride, comprising at least one sensor device which includes a sensor for verifying whether there is a form-fit between the passenger and the mechanism.

A monitoring system for buses includes presence sensors and belt sensors connected to slaves connected to a connection cable to transport the signals from the slaves in such a way to form a field bus. The connection cable is connected to a master that receives the signals from the slaves. The master is connected to a human-machine interface (HMI) by a network cable.

A heat flux sensor is installed in such a way that heat flux emanating from a biological object present at a predetermined position is detectable. It is determined whether or not a biological object is present at the predetermined position by comparing sensing results of the heat flux sensor with determination criteria. The determination criteria is preset according to heat flux that can be sensed when a biological object is present at the predetermined position. When the sensing results of the heat flux sensor satisfy the determination criteria, in other words, when the heat flux sensed by the heat flux sensor is the heat flux emanating from a biological object, it is determined that a biological object is present at the predetermined position. Consequently, it is possible to realize accurate detection of a biological object.
