Methods and systems for generating a composite image in remote sensing applications are described. In an example, a device can receive an image having a plurality of points specified in an image space. The device can extract a portion of the image and transform points among the extracted portion from the image space to a parameter space defined by a distance parameter and an orientation parameter. The device can identify a set of intersection points in the parameter space that indicate at least one occurrence of a geometry feature in the extracted portion of the image. The device can augment the portion of the image with a plurality of new pixels based on the identified set of intersection points. The device can generate a composite image using the augmented image, where the composite image can include a plurality of augmented images corresponding to other portions of the image.

The disclosure describes systems and methods that are configured to measure and generate parking environment data including locations of parking spaces and their occupancy status, and to use the parking environment data to find an unoccupied parking space for a vehicle. In particular, a system is configured to determine the location and occupancy status of parking spaces based on parking environment data received from a vehicle, and to determine a location of an unoccupied parking space based on a database of parking environment data.

Systems and methods for presenting a map and changing a facing direction of an object. In an aspect, an elongated map segment is presented according to a pointing direction of a device. In other aspects, a facing direction of an object is changed according to a pointing direction of a device or a facing direction of a user.

Localization systems and methods for transmitting timestampable localization signals from anchors according to one or more transmission schedules. The transmission schedules may be generated and updated to achieve desired positioning performance. For example, one or more anchors may transmit localization signals at a different rate than other anchors, the anchor transmission order can be changed, and the signals can partially overlap. In addition, different transmission parameters may be used to transmit two localization signals at the same time without interference. A self-localizing apparatus is able to receive the localization signals and determine its position. The self-localizing apparatus may have a configurable receiver that can select to receive one of multiple available localization signals. The self-localizing apparatuses may have a pair of receivers able to receive two localization signals at the same time. A bridge anchor may be provided to enable a self-localizing apparatus to seamlessly transition between two localization systems.

Certain aspects of the present disclosure provide measures, including apparatuses, circuitry, methods and computer programs, for use in monitoring user activity. Orientation data for a user is generated. The generated orientation data is inserted into advertising packets of a wireless communication protocol. The advertising packets comprising the generated orientation data are broadcast according to the wireless communication protocol.

Wireless mobile device functionality can be added to radio devices via a hardware device that comprises wireless network access. Alternatively, radio device functionality can be shared with a wireless mobile device or the hardware device. The functionalities of either device can be shared via a physical or wireless connection. For example, a microphone device comprising a display screen and long-term evolution (LTE) functionality can be connected to a radio device to facilitate LTE functionality for the radio device. Thus, a user of the radio device can utilize the display screen of the microphone device to send text data, which could not previously be sent by the radio device, over the wireless network via the microphone device.

A system and method for operating a terminal facility handling containers may comprise: a sensor set sensing containers entering and/or exiting the facility for providing container identification data and location data to a relational database; and container handling equipment having a sensor set for providing container identification data and location data to the database when a container is grasped and/or released. Sensors may sense when the equipment grasps and/or releases a container for storing a record thereof in the database, and/or geo-tagged identification data and location data relating to carriers that are to pick up and/or to deliver a container is received and stored as records in the database. The relational database contains records representing the current location of each container and each container handling equipment substantially in real time and can estimate arrival time.

A system generating, using a first addressable unit address decoder, a first addressable unit address based on an input address, an interleaving factor, and a number of first addressable units. The system then generating, using an internal address decoder, an internal address based on the input address, the interleaving factor, and the number of first addressable units. Generating the internal address includes: determining a lower address value by extracting lower bits of the internal address, determining an upper address value by extracting upper bits of the internal address, and adding the lower address value to the upper address value to generate the internal address. Using an internal power-of-two address boundary decoder and the internal address, the system then generating a second addressable unit address, a third addressable unit address, a fourth addressable unit address, and a fifth addressable unit address.

Secure communication for autonomous vehicles can be increased by performing authentication operations before nodes, such as vehicles, roadside equipment (RSE), or base stations, are within communications range. A digital certificate management system for mobile nodes, including for moving vehicles, can facilitate ultra fast communications between vehicles and other nodes. The RSE can propagate vehicle node data, comprising direction, speed, or estimated time of arrival, to other vehicles and/or other RSEs. Consequently, this propagation of data prior to the communication between nodes can facilitate an efficient authentication system.

Certain embodiments are directed to techniques (e.g., a device, a method, a memory or non-transitory computer readable medium storing code or instructions executable by one or more processors) for passive beacon communication techniques. Transmitting devices (e.g., beacons) can transmit advertising messages using a first wireless protocol to provide timing for ranging messages for one of more ranging messages over a second protocol (e.g., UWB). One or more receiving devices can determine using signal strength if the devices are within a threshold range to perform communication techniques. Various ranging communications techniques can be used to determine a range between the receiving device and transmitting device. Other techniques can be used to passively calculate the angle of arrival for transmitter signals. The angle of arrival information can be used for precise position locating for the receiving device or to indicate interest in information provided by the one or more transmitting devices.
