An improved aviation transponder is discussed herein. The improved aviation transponder demonstrates improved cohabitation and survivability characteristics, allowing the transponder to be placed near other antennas without causing or receiving interference, and reducing potential damage caused by high-energy electromagnetic fields, such as those experienced near an air traffic control (ATC) or military radar installation. Additionally, a small form factor of the transponder results in a smaller, more compact aircraft that consumes less energy, reduces heat dissipation, and maximizes battery life and/or flight time. The transponder may comply with modular interface standards, and may include a radio configured for transmitting 200-watt signals. Based at least in part on the improved performance, the transponder can be implemented in unmanned aerial vehicles (UAVs), for example.

A tracking system determines a location of a tracking device associated with a user using one or more access points at the location. Each access point at the location is configured to detect and couple with the tracking device when the tracking device is within a communicative range of the access point. An access point provides updates on the tracking device's presence, as well as the tracking device's arrival to and departure from the communicative range of the access point, to a tracking server. The tracking server determines, from these updates, whether the tracking device is at the location. The user may be notified, via a mobile device, of the tracking device's location.

A delivery data server includes at least one processor that executes a delivery data server application to bidirectionally communicate delivery data with a first user of a first client device via a network. The delivery data includes delivery menu data sent to the first client device and delivery location data received from the first client device that indicates a service address associated with a user of the first client device and a delivery location associated with the service address for receiving at least one delivery to the service address. The delivery data server application processes the delivery location data to direct the at least one delivery to the service address.

A system for creating of list of active beacons includes at least one receiving device, comprising a receiver adapted to receive a beacon broadcast from one or more of a plurality of beacons, resulting in one or more received beacon broadcasts, a processor, a memory, and a smart beacon application. For each received beacon broadcast comprising informational data and data regarding a range of relevance for that beacon, the smart beacon application: 1) determines whether the beacon is relevant by comparing a strength of the received beacon broadcast to the range of relevance in the beacon broadcast, and 2) creates a list of relevant beacons.

An electronic verification system is provided, comprising: (I) multiple electronic verification devices (120), comprising: a beacon receiver (124) arranged to receive localizing beacon signals transmitted from multiple beacons (110) installed in the vicinity of the multiple verification devices, the verification device transmits the beacon message to an external beacon verification computer, and (II) the beacon verification computer (130) configured to analyze the multiple beacon messages to determine if a localization system comprising the multiple beacons is functioning correctly.

An object monitoring system including a plurality of location beacons, each location beacon being configured to generate a location broadcast message indicative of a beacon location and a tag associated with a respective object in use. The includes a tag memory configured to store object rules, a tag transceiver configured to transmit or receive messages and a tag processing device configured to determine context data at least partially indicative of a tag context by at least one of determining a tag location in accordance with at least one location broadcast message received via the tag transceiver from at least one of a plurality of location beacons and using stored context data, use the object rules and the context data to identify a trigger event, determine an action associated with the trigger event and cause the action to be performed.

The present invention relates to a method for indoor localization of a user equipped with a localization device having electromagnetic signal receiver means and means for detecting the orientation in a predetermined spatial reference system, wherein the indoor space is divided up into a plurality of rooms each of which includes a plurality of spatial volumes or areas, nodes, which are connected together in a directed-graph arrangement, and wherein a plurality of radio transmitters each designed to emit a respective localization signal are arranged inside this space. The method is based on the synergic use of three localization methods, i.e. fingerprinting, inertial navigation with intelligent step recognition and proximity localization.
