A vehicle-mounted alert system includes display devices equipped to a vehicle, a sight line detection device detecting driver's sight line, a surrounding monitoring device detecting a presence of an object near the vehicle and a direction of the object with respect to the vehicle, and an alert control device controlling the display devices to display an alert image for informing the driver of the presence of the object detected by the surrounding monitoring device. The alert control device controls the display device located in a direction of the sight line of the driver to display the alert image, and then, controls the display devices so that the alert image successively moves from the display device located in the direction of the sight line of the driver to the display device determined based on the direction of the object detected by the surrounding monitoring device.

A vehicle sensing system is for being disposed on a vehicle. The vehicle sensing system includes a calculating unit, which includes a turning calculating module and a vehicle dimension dataset. The vehicle dimension dataset includes at least one of a wheelbase, a vehicle width, a front overhang and a rear overhang of the vehicle. The calculating unit is configured to receive a turning dataset of the vehicle. Based on the turning calculating module, the calculating unit is configured to determine an inner front wheel and an inner rear wheel. The calculating unit is configured to further determine a turning alarm zone in accordance with the vehicle dimension dataset and the turning dataset. The turning alarm zone is dependent on at least one of time and the turning dataset.

There is provided a work machine information processing device including a risk detector configured to detect a risk relating to a state or a surrounding environment of a work machine, notifier configured to notify an operator of the work machine of the risk detected by the risk detector, behavior detector configured to detect a behavior of the operator after the notification of the notifier, and calculator configured to calculate a safety behavior evaluation value obtained by quantitatively evaluating the behavior of the operator in terms of a degree of contribution to the safety, based on contents of the risk detected by the risk detector and the behavior of the operator detected by the behavior detector.

A safety alert system includes a child seat that may be positioned within a vehicle. The child seat has a plurality of belts and each of the belts may restrain a child in the child seat. A remote unit may be retrofitted to a dome light of the vehicle. The remote unit generates an alarm sequence when a door of the vehicle is opened. A base unit is removably coupled to the belts on the child seat and the base unit is in electrical communication with the remote unit. The base unit emits an audible alarm when the remote unit generates the alarm sequence. Thus, the base unit may prevent the child from being inadvertently left unattended in the vehicle.

The present application provides an obstacle detection system and method thereof. The obstacle detection method comprises: obtaining a first image captured by a camera at a first time point; identifying a vertical edge candidate in the first image, and measuring a first length of the vertical edge candidate based on the first image; obtaining a second image captured by the camera at a second time point; measuring a second length of the vertical edge candidate based on the second image; calculating a difference between the first length and the second length; and comparing the difference with a predetermined length difference threshold, if the difference is greater than the length difference threshold, outputting a message that an obstacle is found.
