A network comprises a network apparatus constructed and arranged for each of a plurality of vehicles in radio frequency (RF) communication with each other, the network apparatus comprising: at least one first transceiver; at least one second transceiver configured to exchange RF signals with the at least one first transceiver; receiver circuitry configured to determine timing information from the acquired RF signals; memory storing information related to fixed distances between the at least one first transceiver and the at least one second transceiver; a processor coupled to the memory to access the stored information related to the fixed distances, and to the receiver circuitry to receive the timing information determined from the RF signals, the processor being configured to determine a relative position of the vehicle with respect to a receipt of the RF signals based on the stored information related to the fixed distances between each of at least three spatially separated antenna and on the timing information determined by the receiver circuitry; and a control system configured to control operation of the vehicle in response to the relative position of the vehicle, determined by the processor.

Spatial diversity for relative position tracking

Methods and systems for tracking a package within an area obtain package identification information from a scannable medium associated with the package and image information of the area acquired by an optical sensing device. Image processing detects the presence and location of an object in the area that matches the package based on a comparison of the package identification information obtained from the scannable medium with the image information of the area acquired by the optical sensing device. The package is registered as being present in the area at the location of the detected object in response to detecting a match between the object and the package.

Package tracking systems and methods

Methods and apparatus for providing validation of data from the tracker devices. In embodiments, a method includes registering a tracker device with a device registry and issuing by an issuer the tracker device to a third party. Raw and signed data is collected from the tracker device is hashed and stored to enable later validation of the data.

Methods and apparatus for a plurality of electronic sensor devices configured to take and report sensor readings or measurements relating to an asset with which each device is associated to a remote computer system. One of the devices at a given time has wide area network (WAN) connectivity as a designated device to communicate with the remote computer system using wide area network connectivity. The designated device and the other devices take sensor readings and measurements and the other devices to report sensor readings and measurements to the designated device using local area network (LAN) connectivity. The designated device reports sensor readings and measurements received from the other devices to the remote computer system using wide area networks connectivity. It is detected when a battery in the designated device has reached a charge level below a defined threshold. One of the other devices is assigned as the designated device.

Multi-sensor electronic device with wireless connectivity and sensing as a service platform and web application

Vehicles and methods of navigating vehicles comprise at least three receiver antennae configured to receive radio frequency (RF) signals from one or more RF-transmitting antennae coupled to an object, receiver circuitry coupled to the receiver antennae to acquire the RF signals and to determine timing information from the acquired RF signals, memory storing information related to fixed distances between each receiver antenna and each other receiver antenna, a processor configured to determine a relative position of the vehicle with respect to the one or more RF-transmitting antennae based on the stored information related to the fixed distances between each receiver antenna and each other receiver antenna and on the timing information determined by the receiver circuitry, and a control system configured to control operation of the vehicle in response to the relative position of the vehicle with respect to the one or more RF-transmitting antennae determined by the processor.

Methods and apparatus for configuring a sensor device in accordance with a first configuration defining data collection for a plurality of sensors and defining when the collected data for the sensors is transmitted to a remote network. The sensor device can be coupled to a shipping container for collecting environmental data as the shipping container is en route to a destination. The sensor device can receive a transition signal from the remote network instructing the sensor device to transition to a second configuration with different transmission parameters.

Linearization circuits and methods for multilevel power amplifier systems

A tracking system is described having at least two mobile transmitter/receivers ('transceivers') which sense and respond to at least one tracking transceiver. The signals sent to and received from the mobile transceivers are analyzed to get a distance (range) that each is from the tracking transceiver. This can be converted into a position relative to the mobile transceivers. If there are enough transceivers, and at least one knows its absolute location, the absolute location of the mobile transceivers may be determined. Existing smartphones, cellphones, WI-FI&#xae; wireless standard routers, BLUETOOTH&#xae; wireless standard devices, and near-field devices that have on-board processors, can be modified to run executable code to implement the current invention. They may communicate using at least one of the modalities for tracking. These may be implemented in tracking the position and orientation of moving devices, such as a head-mounted display for virtual/Augmented Reality, automobiles, packages in a package delivery truck. The system may also be implemented to identify and keep track of the last known location of various objects.

Accurate geographic tracking of mobile devices

Methods and apparatus processing acceleration data of a sensing device to determine whether the device is located on an aircraft during landing or taking off or in the air or landed. Based on a state of the sensing device, such as take-off, the sensing device is prevented from transmitting signals. In embodiments, the sensing device compares network identifying information stored in memory of the sensing device and locally received network identifying information. For at least one positive comparison of the network identifying information stored in the memory and the locally received network identifying information, the sensing device is prevented from transmitting signals. In embodiments, the acceleration data and the network identifying information provide independent ways to selectively prevent the sensing device from transmitting signals.

Selective prevention of signal transmission by device during aircraft takeoff and/or landing

Systems and methods improve virtual reality and augmented reality functionality for mobile devices using radio frequency (RF) signals transmitted by a tracked device and received at four or more spatially separated antennae. These antennae are connected, wirelessly or through wired connections, to a base station. Through RF signal time of arrival information acquired at the antennae, the base station can continuously determine accurate position information of the tracked device, without lighting or line of sight limitations experienced by camera and other optical systems. As the position of the RF-transmitting tracked device is registered within a virtual environment produced by an interactive software program in communication with (or part of) the base station, the virtual viewpoint of the tracked device is controlled to reflect the relative position and orientation of the tracked device with respect to the virtual environment produced by the software program and displayed on a view screen.
