  • Publication number: 20250083649
    Abstract: A method of automated vehicle braking control includes detecting a first object threat in a reverse travel path of a vehicle, monitoring a distance of the vehicle from the first object threat with respect to a time to collision threshold, and in response to a determination that the vehicle is crossing the time to collision threshold, initiating a first rear virtual bumper event by automatically applying brakes of the vehicle. The method includes storing a location of the first object threat, defining a boundary region surrounding the location of the first object threat, detecting a second object threat in the reverse travel path, comparing a location of the second object threat with the boundary region, and inhibiting automatic application of the brakes in response to a determination that the location of the second object threat is within the boundary region, to avoid a second rear virtual bumper event.

  • Publication number: 20240426951
    Abstract: An ultrafast wide-field quantum sensing device using a neuromorphic event-based vision sensor includes a laser generating a laser beam; a dichroic mirror directing the laser beam onto a diamond sample and passing the laser beam reflected from the diamond, and an event camera receiving from the dichroic mirror the beam reflected from the diamond. A source of microwave energy applied to the diamond. A pulse generator synchronizes the microwave source and the event camera to create CW-ODMR measurements, wherein trigger pulses from the pulse generator are applied to the camera and microwave source. The optically detected magnetic resonance (ODMR) resonance frequency is determined based on the CW-ODMR measurements.

  • Publication number: 20240414866
    Abstract: Disclosed are an electronic device housing including a casing and a seal, and an electronic device. The casing has an interior provided with an accommodating cavity configured to accommodate electronic device components, and a casing wall provided with a mounting cavity configured to mount the seal. The casing includes first and second through holes. The first and second through holes communicates the mounting cavity with the accommodating cavity and an outside, respectively. The seal includes a sealing part and a fixing part connected thereto. The fixing part is fixed to the casing wall, and the sealing part blocks the first through hole. The sealing part has elasticity. When pressure in the accommodating cavity is greater than that of the outside, at least part of the sealing part is separated from the first through hole, such that the accommodating cavity communicates with the mounting cavity to communicate with the outside.

  • Patent number: 12139073
    Abstract: Vehicles and systems and methods for providing rearview displays for vehicles are provided. An exemplary system is provided for a vehicle having a gate moveable between closed configuration and opened configurations. The system includes a camera mounted to the gate and configured to collect dynamic pixel images of an area behind the vehicle; a display screen configured to display the collected dynamic pixel images; and memory configured to include executable instructions and a processor configured to execute executable instructions that enable the processor to crop the collected dynamic pixel images to display a lower portion of the collected dynamic pixel images on the display screen when the gate is in the closed configuration, and to crop the collected dynamic pixel images to display an upper portion of the collected dynamic pixel images on the display screen when the gate is in the opened configuration.

  • Patent number: 11131992
    Abstract: A RLP system for a host vehicle includes a memory and levels. The memory stores a RLP algorithm, which is a multi-agent collaborative DQN with PER algorithm. A first level includes a data processing module that provides sensor data, object location data, and state information of the host vehicle and other vehicles. A second level includes a coordinate location module that, based on the sensor data, the object location data, the state information, and a refined policy provided by the third level, generates an updated policy and a set of future coordinate locations implemented via the first level. A third level includes evaluation and target neural networks and a processor that executes instructions of the RLP algorithm for collaborative action planning between the host and other vehicles based on outputs of the evaluation and target networks and to generate the refined policy based on reward values associated with events.

  • Publication number: 20200034351
    Abstract: Systems and methods are disclosed and include a node storing a local table and a control module that collects heterogeneous sensor data, tracks objects in an environment of the node, and converts the heterogeneous sensor data into time series data. An object-relational mapping module formats the time series data for direct compatibility to data in a master database of a cloud-based server. A correlation module further formats the time series data to provide resultant data in a single format commonly used by multiple map sources. A first primitive extraction module extracts primitives from the resultant data. An edge computing module generates a first table of data corresponding to the primitives and compatible with a master table of the master database, detects a changed primitive, uploads the changed primitive to the cloud-based server, receives updated data based on the changed primitive, and updates the local table based on the updated data.

  • Publication number: 20190392309
    Abstract: An AI system is provided and includes a long short term memory and data processing, feature selection, behavior recognition, parameter, and driver assistance modules. The data processing module, at a host vehicle: receives training data associated with features; based on the training data, determines candidate features using a synchronous sliding window; and indexes and ranks the candidate features. The feature selection module selects ones of the candidate features having higher priority than other ones of the candidate features and filters the training data of the selected features to provide filtered data. The behavior recognition module determines a behavior of a remote vehicle based on the filtered data. The parameter module determines a parameter of the remote vehicle based on the determined behavior. The long short term memory predicts a value of the parameter. The driver assistance module assists in operation of the host vehicle based on the predicted value.
