Improving automated package delivery to mobile delivery receptacles to allow accurate and reliable package deliveries comprises a delivery receptacle for an automated package delivery via an unmanned aerial delivery device. The delivery receptacle is notified of a pending delivery and travels to a receiving location. The delivery receptacle emits infrared (IR) beacons from one or more IR beacon transmitters. An aerial delivery device detects the IR beacon and uses the beacons to navigate to the delivery receptacle. The delivery receptacle receives IR beacon responses from the aerial delivery device and continually or periodically directs the IR beacons in the direction of the aerial delivery device. The aerial delivery device deposits the package in the delivery receptacle. After receiving the package, the delivery receptacle transports the package to a secure location, such as into a garage.

A Bluetooth beacon for a luminaire assembly includes a module and an antenna associated with the module. The Bluetooth beacon is monted such that the antenna is communicatively visible from a light emitting side of the luminaire assembly. The Bluetooth beacon is configured to provide a signal extending a predetermined distance from the luminaire assembly such that a Bluetooth receiver on a user device can receive a signal from the Bluetooth beacon.

A system for tracking assets. The system includes a visible light source that includes a wireless signal generator configured to produce wireless signals and a tag that includes a detector that detects the presence of the wireless signals produced by the visible light source. The tag includes a transmitter that is configured to send additional wireless signals. The system further includes a tag monitor that includes a receiver that is configured to receive the additional wireless signals. The tag monitor determines a location of the tag based on the additional wireless signals received from the tag.

According to one embodiment of the present invention, a method by which a terminal receives a reference signal for determining a position in an unlicensed band in a wireless communication system can comprise the steps of: receiving positioning reference signal (PRS)-related configuration information transmitted through the cooperation of one or more unlicensed band cells, wherein the PRS-related configuration information includes information on a plurality of sub-bands in the unlicensed band, in which the PRS is transmitted, and information on a PRS transmission period for each of the plurality of sub-bands; receiving and measuring the PRS by using the PRS-related configuration information; and reporting the PRS measurement result to a serving cell.

A method for energy management in a robotic device includes providing a base station for mating with the robotic device, determining a quantity of energy stored in an energy storage unit of the robotic device, and performing a predetermined task based at least in part on the quantity of energy stored. Also disclosed are systems for emitting avoidance signals to prevent inadvertent contact between the robot and the base station, and systems for emitting homing signals to allow the robotic device to accurately dock with the base station.

Methods and apparatuses are provided for use in monitoring product placement within a shopping facility. Some embodiments provide an apparatus configured to determine product placement conditions within a shopping facility, comprising: a transceiver configured to wirelessly receive communications; a product monitoring control circuit coupled with the transceiver; a memory coupled with the control circuit and storing computer instructions that when executed by the control circuit cause the control circuit to: obtain a composite three-dimensional (3D) scan mapping corresponding to at least a select area of the shopping facility and based on a series of 3D scan data; evaluate the 3D scan mapping to identify multiple product depth distances; and identify, from the evaluation of the 3D scan mapping, when one or more of the multiple product depth distances is greater than a predefined depth distance threshold from the reference offset distance of the product support structure.

Disclosed are systems and methods for tracking position of a mobile device within a venue. In an aspect, the mobile device obtains a plurality of light source identifiers and a plurality of location identifiers corresponding to a plurality of light sources within the venue, determines a first position of the mobile device within the venue, the first position having a first position accuracy, determines a subset of the plurality of light source identifiers corresponding to a subset of the plurality of light sources based on a location of each light source in the subset of light sources being within a threshold distance of the first position, demodulates a fragment of a light source identifier, and determines a second position of the mobile device based on one or more location identifiers corresponding to the light source, the second position having a greater position accuracy than the first position accuracy.

Provided is a guidance display device which transmits predetermined information by visible light communications, the guidance display device including: a light source which emits light for visible light communications, the light including the predetermined information; a housing covering the light source and having a first light-exit surface which transmits the light emitted by the light source; a first guidance display on the first light-exit surface; and a first mark on the first light-exit surface, wherein the first mark has a shape corresponding to a total number of light-exit surfaces, including the first light-exit surface, of the guidance display device through which the light for visible light communications emitted by the light source exits.
