Abstract: A method for distracted driver detection and alert includes receiving vehicle speed data from one or more wheel speed sensors disposed on the vehicle and receiving proximity data from one or more proximity sensors disposed on the vehicle, the proximity data indicating a distance of the vehicle relative to any objects in front of the vehicle. The method also includes executing a distracted driver detection algorithm that uses the vehicle speed data and the proximity data to determine the vehicle is disrupting a flow of stop and go traffic and a driver of the vehicle is distracted from operating the vehicle. The method includes, based on determining that both the vehicle is disrupting the flow of stop and go traffic and the driver of the vehicle is distracted, instructing a system of the vehicle to output an alert to reengage the driver.

Abstract: A method is described. The method can include establishing a block chain network of multiple imaging devices. The block chain network can be established such that, at least a first imaging device of the multiple imaging devices can be validated by at least a second imaging device of the multiple imaging devices. Further, the method can include generating a block message by the first imaging device. The block message can be generated by using a secured hash function and based on a set of parameters that can be associated with the first imaging device. The set of parameters can include, a first imaging device identifier, a network fluctuation parameter, and at least one inertial parameter. Furthermore, the method can include sending by the first imaging device the block message to the second imaging device. In this regard, the block message can facilitate validation of the first imaging device.

Abstract: A roller tappet including bearing sleeves is disclosed. The roller tappet includes a housing having a circumferential sidewall with a first sidewall portion including a first bore and a second sidewall portion including a second bore diametrically opposed to the first bore. A roller is positioned at least partially inside the housing between the first sidewall portion and the second sidewall portion. A first bearing sleeve is arranged in the first bore of the housing and a second bearing sleeve arranged in the second bore of the housing. An axle extends through the first bearing sleeve and the second bearing sleeve and through the roller, such that the roller is rotatably mounted on the axle within the housing. Axial ends of the axle are respectively positioned in and rotatable relative to the first bearing sleeve and the second bearing sleeve.
