Abstract: A transmitting/receiving device for a bus system and a method for reducing an oscillation tendency in the transition between different bit states. The transmitting/receiving device has a transmitting stage for transmitting a transmission signal to a first bus wire of a bus of the bus system and for transmitting the transmission signal as an inverse signal to a second bus wire of the bus, and an asymmetry reduction module for reducing an asymmetry of bus signals arising in the bus wires. The asymmetry reduction module includes a polarity reversing diode, whose cathode is connected to the cathode of a reverse polarity diode of the transmitting stage. The asymmetry reduction module switches a potential of the cathode of the polarity reversing diode to a potential that is greater than or equal to a level of a recessive bus state.

Abstract: The present invention obtains a controller and a control method capable of appropriately emitting an emergency braking signal in a straddle-type vehicle. A controller (60) and the control method according to the present invention control operation of a straddle-type vehicle (100) in which anti-lock brake control for a front wheel (3) and anti-lock brake control for a rear wheel (4) are executed. An acquisition section of the controller (60) acquires an anti-lock brake actuation state showing whether the anti-lock brake control is actuated for any of the wheels (3, 4). A determination section of the controller (60) determines a threshold value on the basis of the anti-lock brake actuation state. An output section of the controller (60) outputs an emergency braking signal command in the case where deceleration of the straddle-type vehicle (100) is higher than the threshold value.

Abstract: Methods and systems are disclosed for generating training data for a machine learning model for better performance of the model. A source image is selected from an image database, along with a target image. An image segmenter is utilized with the source image to generate a source image segmentation mask having a foreground region and a background region. The same is performed with the target image to generate a target image segmentation mask having a foreground region and a background region. Foregrounds and backgrounds of the source image and target image are determined based on the masks. The target image foreground is removed from the target image, and the source image foreground is inserted into the target image to create an augmented image having the source image foreground and the target image background. The training data for the machine learning model is updated to include this augmented image.
