The disclosure relates to a method for requesting and granting priority between a host vehicle and other vehicles, and to a system which implements the method. The host vehicle, through the use of on-board vehicle sensors, detects and identifies an impeding vehicle which interferes with the host vehicle's path. The host vehicle transmits a priority request to the impeding vehicle. The priority request includes a remuneration offer. The impeding vehicle evaluates the priority request, including the sufficiency of the host vehicle's remuneration offer, and grants or denies the host vehicle's priority request. If granted, the impeding vehicle modifies its path to be less impeding to the host vehicle, for example by assuming a cooperative path that lets the host vehicle pass the impeding vehicle.

A system and methods for estimating the location of a mobile device are disclosed. In accordance with one embodiment, a mobile device located within a first corridor of a building receives (1) a first wireless electromagnetic signal and a first ultrasound signal from a first beacon located in the first corridor, (2) a second wireless electromagnetic signal and a second ultrasound signal from a second beacon located in the first corridor, and (3) a third wireless electromagnetic signal from a third beacon located in a second corridor of the building. The first wireless electromagnetic signal, the first ultrasound signal, the second wireless electromagnetic signal, and the second ultrasound signal are used to estimate a location of the mobile device.

The present disclosure relates to a location determination system that includes acoustic transmitting devices (104), location tags (112), and a wireless mesh network (106), where the wireless mesh network uses battery-powered devices. A location tag receives acoustic signals (e.g., ultrasound signals) from an acoustic transmitting device. Clocks from members of the wireless mesh network are synchronized by observation of clock pairings, each clock pair formed by respective clocks in a transmitting device that transmits a message and a receiving device that receives the message. By analyzing the observed clock pairings, a best fit between the clock pairings may be determined. After selecting a reference clock, an acoustic transmission schedule may be propagated to the respective acoustic transmitting device.

A system and methods for estimating the location of a mobile device are disclosed. In accordance with one embodiment, a mobile device receives an ultrasound signal lacking an identification of the source of the ultrasound signal. One or both of the mobile device or a server identify which of a plurality of beacons transmitted the ultrasound signal based on the time at which the mobile device received the ultrasound signal and the time at which the mobile device received a wireless electromagnetic signal prior to receiving the ultrasound signal. One or both of the mobile device or the server estimate a location of the mobile device based on the identified beacon and on the times at which the mobile device received the wireless electromagnetic and ultrasound signals.

Introduced here are recording devices optimized for recording speech between multiple parties (e.g., a speaker and a counterparty, or a first speaker and a second speaker). These recording devices can facilitate the discovery of personalized characteristics of an interaction by detecting location. For example, these recording devices can discover the intent behind certain terms and phrases in the context of a conversation. A recording device can include a communication module configured to stream recorded media content to another electronic device, as well as a marker identification module configured to identify nearby beacons. For example, a recording device may include a Bluetooth Low Energy chipset configured to identify nearby Bluetooth beacons and a Wi-Fi chipset configured to stream recorded media content to another electronic device.

A system, device and method that enables units to communicate with each other and point to each other's location without requiring line-of-sight to satellites or any other infrastructure. Further, the system, device and method are able to operate outdoors as well as indoors and overcome multipath interference in a deterministic algorithm, while providing bearings at three dimensions, not only location but actual direction.

A programmable buoy system having one or more buoys capable of connecting through the Internet to a buoy command server. The buoy command server relays commands to each of the one or more buoys in response to user commands sent from a buoys command interface application on a mobile device. The programmable buoy system includes one or more buoys each having a hull with two or more pontoons where the hull has a top side and bottom side. A stationary rudder extends downward from the bottom side of the hull to be positioned in a body of water when the one or more buoys are in use. A motor is pivotably connected on each one or more buoys, wherein the motor has a propeller positioned away from the bottom side of the hull. The propeller and motor move the select one of the one or more buoys in the body of water.
