Abstract: The disclosure pertains to using ultra-wideband (UWB) radio communications to execute a pedestrian-vehicle rendezvous. In one example operation, a personal device such as a smartphone, is used to identify a location of a vehicle with a first level of accuracy. For example, the smartphone may be used by a pedestrian to obtain GPS location coordinates of a ride-hail vehicle summoned by the pedestrian. The vehicle may be located relatively far from the pedestrian. The smartphone may be configured to automatically establish a UWB radio link with a UWB transponder in the vehicle and/or a smartphone carried by a driver of the ride-hail vehicle, when the vehicle is within range to establish UWB communications. The UWB radio link may be used to execute one or more of various procedures to locate the vehicle with a second level of accuracy that is higher than the first level of accuracy.

Abstract: A display device includes: a display layer having a display area including a plurality of pixel areas and a peripheral area at least partially surrounding the display area; and a cover layer disposed on the display layer to encapsulate the display area. The cover layer includes: a light blocking portion overlapping the display area and the peripheral area and including a plurality of openings to transmit light from the plurality of pixel areas and to block light in the peripheral area; a first protrusion disposed on the light blocking portion in the peripheral area and surrounding the display area; and an overcoating layer covering the display area and contacting a lateral surface of the first protrusion.

Abstract: A vehicle controller communicates with a cellular communication system to request content. The content is transmitted to one or more road side units with storage (RSS) lying on the vehicles known or inferred trajectory. When the vehicle passes by the RSS some or all of the content is transmitted to the vehicle using a short-range, high-bandwidth communication protocol. The content may be divided into segments and each segment sent to an RSS. The segments are sized according to a capacity of the RSS and the amount of time the vehicle is expected to spend traversing a range of the RSS. Content may be cached in the RSS for use by other vehicles.

Abstract: An interface device including: a first fixed portion and a first rotation portion which are fixed to a body; a first power portion which is connected to the first fixed portion and the first rotation portion and provides power to the first rotation portion; and a control unit which controls, when receiving a signal from an external device, the first power portion to control rotation of the first rotation portion, wherein the first power portion switches the first rotation portion to a free state of being rotatable by external force or a control state of being not rotatable by external force.

Abstract: Transportation infrastructure provides for vehicle-to-infrastructure (V2I) communication over a vehicle-to-everything (V2X) communication network with a V2X transceiver of a vehicle in accordance with a subscription level defining a level of access of the vehicle to data services of a cellular network. An interface controller operates as a gateway between the cellular network and the V2X communication network. A vehicle includes a transceiver for V2X communication. The transceiver provides for V2I communication over a V2X communication network with transportation infrastructure in accordance with a subscription level defining a level of access of the vehicle to a cellular network, and also provides for vehicle-to-vehicle (V2V) communication over the V2X communication network with other vehicles in accordance with the subscription level.

Abstract: Example vehicle communication management systems and methods are described. In one implementation, a communication management system determines whether a vehicle can communicate with an external system. If the vehicle is unable to communicate with the external system, the communication management system identifies a neighboring device that can communicate with the external system and communicates vehicle information to the neighboring device. The communication management system also requests the neighboring device to communicate the information, and other details from the neighboring device's perspective, to the external system.

The force feedback method includes detecting occurrence of a contact event that a virtual user object contacts a single virtual object; setting a writing pressure of a user object in the contact event; and setting a force feedback control variable based on the writing pressure.

Abstract: One or more processors associated with a vehicle can be configured to determine whether a condition exists that requires a request for assistance, such as a vehicle malfunction, a passenger emergency, and so forth. In response to a determination that the condition exists, the processor(s) determine availability of remote objects or devices with which the vehicle can communicate wirelessly. In response to a determination that no remote object or device is available, the processor(s) cause a visible light communication (VLC) transmitter to transmit the request for assistance.
