    Abstract: A system for facilitating the effective administration of cardiopulmonary resuscitation (CPR) by providing feedback regarding release velocity, which is the velocity of the chest while resiliently expanding during the upstroke of a CPR compression cycle. The feedback is provided, indicating whether the CPR provider has substantially released the chest, through a control systems which analyzes sensor input corresponding to chest displacement to determine chest compression depth and release velocity, compares the determined release velocity to a desired release velocity threshold. The desired release velocity is determined based on the depth of compression. The desired release velocity may be determined based on assumed or target compression depth, selected by a CPR provider and input into the control system, or the desired release velocity may be determined adaptively, based on the chest compression depth achieved during compressions and/or the rate of compressions, as determined by the control system.

    Abstract: It is determined whether a traffic light is recognized in an image based on each of a result of a recognition operation by a traffic light first recognition unit (a recognition operation of the traffic light for an image acquired by a camera using a learned model based on pre-annotated data) and a result of a recognition operation by a traffic light second recognition unit (a recognition operation of the traffic light for an image acquired by the camera based on a feature amount of the traffic light). This makes it possible to sufficiently obtain the recognition accuracy of the traffic light, and to appropriately perform an instruction to a pedestrian according to the state of the traffic light.
