A tire pressure monitoring system used for a vehicle includes a sensor unit, a receiving device, and a control device. The sensor unit is provided at each wheel of the vehicle, detects tire pressure of the each wheel with a tire pressure sensor and transmits data of the detected tire pressure by radio waves. The receiving device includes a receiving antenna that is provided at an outside of the vehicle to receive the data of the tire pressure transmitted from the sensor unit. The control device includes a data acquisition unit that acquires the data of the tire pressure received by the receiving device.

Example systems, devices, media, and methods are described for tracking one or more movable objects and presenting virtual elements on a display in proximity to the tracked movable objects. One or more ultra-wideband (UWB) transmitters are mounted to each movable object in a physical environment including at least two synchronized UWB receivers. The receivers calculate a current location of each movable object. A plurality of portable electronic devices, including one or more eyewear devices, are paired with the receivers in a network. A localization application determines a current location of each eyewear device. A rendering application presents one or more virtual elements on a display as an overlay relative to the current movable object location and in relative proximity to the current eyewear location. The physical environment is represented by a static mesh. A time synchronized tracking application identifies moving items that are not coupled to a UWB transmitter. The rendering application presents the virtual elements on the display in accordance with the static mesh and the moving items.

Techniques described herein provide for the efficient usage of an RF channel for PRS transmissions by performing LBT sensing for a group of one or more vehicles (e.g., V2X vehicles) in a predetermined area by using an RSU. The RSU can determine a sequence in which an order for each vehicle in the group to transmit a respective PRS is defined, and provide the sequence to the group. The RSU may further perform the LBT functionality by listening to availability on the RF channel and, when the channel becomes available, the RSU can initiate this sequence by sending an initial PRS. This LBT sensing for a group can provide far more efficient usage of the RF channel than if LBT functionality were performed by each divisional vehicle.

A method for managing a ping rate for a shipment tracking device includes determining, a battery life for a power source of a shipment tracking device associated with a shipment between an origin location and a destination location. The method further includes determining a budget of pings for data transfer by the shipment tracking device, where a ping includes various data collected by a plurality of sensors on the shipment tracking device. The method further includes determining, based on the battery life for the power source and the budget of pings for the data transfer, a transit ping rate for an initial portion of a transit route. The method further includes responsive to receiving a first ping from the shipment tracking device with a first set of the various data, updating the transit ping rate based on the first ping with the first set of data.

Methods, apparatuses, systems, and non-transitory computer-readable medium are disclosed relating to abnormal transmission identification. One method comprises, at a receiving device, receiving a V2X message from a transmitting device. The method further comprises determining a signal propagation context for the receiving device and obtaining an RSSI value and a distance value for the V2X message. The method further comprises generating an adjusted RSSI value based on (1) the RSSI value and (2) the signal propagation context for the receiving device. The method further comprises obtaining a predetermined RSSI-to-distance relationship model and comparing an adjusted RSSI-to-distance data pair, comprising the adjusted RSSI value and the distance value, to the predetermined RSSI-to-distance relationship model. The method further comprises, in response to determining that the adjusted RSSI-to-distance data pair fails a criterion for conforming to the predetermined RSSI-to-distance relationship model, identifying the V2X message as an abnormal transmission.

An interference detection system in a network identifies a first wireless station that has experienced radio frequency (RF) interference from an unknown source and identifies one or more second wireless stations that have experienced similar interference. A plurality of estimated interference source locations are scored based on a comparison of estimated interference to observed interference at the one or more second wireless stations. A predicted interference source location is identified based on the scored plurality of estimated interference source locations. It is determined whether the unknown interference source is a persistent interference source over a selected time period, wherein the predicted interference source location is identified for each interval in the selected time period. The predicted interference source locations for each interval in the selected time period are retrieved and an aggregated predicted interference source location is calculated based on the retrieved predicted interference source locations.

A vehicle is provided that includes a vehicle body, a plurality of RF signal receivers located at a plurality of locations within the vehicle, a portable pet bowl configured to be transported in the vehicle body, the pet bowl including a container for holding content such as water, an RF signal transmitter located on the pet bowl for transmitting an RF signal, and a controller for processing the RF signal received by each of the plurality of RF signal receivers and determining a location of the pet bowl based on the received RF signals.

Apparatus and methods of artificial intelligent based provision of digital content where and when the digital content is needed based upon where an agent is located and a purpose for accessing the content. A location of a user seeking to access the digital content may be used that enables access to the content. Persistent digital content is linked to location coordinates. A physical onsite location may be linked with digital content to enable provision of a user interface with augmented reality that combines aspects of the physical area with location specific digital content. In addition, access to digital content may be limited to users in defined access areas.

A vehicle lighting control apparatus includes a light control unit, a first detection unit and a second detection unit. The first detection unit detects a target object present outside an illumination range of a low beam of a vehicle, using a far-infrared camera. The second detection unit detects a location of the target object detected by the first detection unit, using a ranging sensor that measures a distance with a laser. The light control unit illuminates the location of the target object detected by the second detection unit with a marking light that can illuminate an area at a greater distance when compared with the low beam.
