Abstract: This disclosure describes a system for managing inventory as it transitions into a materials handling facility, as it transitions between locations within a materials handling facility and/or as it transitions out of a materials handling facility. In some instances, a user (e.g., picker or picking agent) may retrieve an item from an inventory location and place the item into a tote. The systems described herein detect the item when it is added to or removed from the tote.

Abstract: A user device receives a command to transmit information at a transmit power level specified by a wireless carrier. The user device determines whether transmitting the information at the specified transmit power level using a first duty cycle will cause the user device to violate a condition. Responsive to determining that transmitting the information at the specified transmit power level using the first duty cycle will cause the user device to violate the condition, the user device determines a new duty cycle that is lower than the first duty cycle, and transmits the information using the new duty cycle.

Abstract: Wireless mesh network (WMN) architectures of network hardware devices organized in a mesh topology is described. One device communicates, using a first radio, first data with a second device via a first wireless link between the device and the second device. The device communicates, using a second radio, second data with a third device via a second wireless link between the device and the third device. The device communicates, using a third radio, third data with a fourth device via a third wireless link between the device and the fourth device. The device communicates, using a fourth radio, fourth data with a server of a content delivery network (CDN) via a point-to-point wireless link between the device and the server. The device is an only ingress point for content files for a mesh network that includes at least the device, the second device, and the third device.

Abstract: Described are techniques for determining occurrence of an error within a system of related devices. If the device affected by the error is not known, other devices within the system may be used to determine whether a device is unresponsive, non-functional, or limited in functionality. The other devices may also be used to determine data indicative of characteristics of the error, such as statuses and activities of devices at or near the time of the error, which may be used to generate a query. The query may be used to determine possible control actions that may address the error or prevent subsequent errors.

Abstract: Network hardware devices organized in a wireless mesh network (WMN) in which one network hardware devices includes multiple radios. A processing device of a first network hardware device receives, via a first radio, a beacon frame from a second mesh network device, scans, via a second radio, for a second mesh frame of the second mesh network device, and receives the mesh frame. The processing device determines a first sector identifier that identifies an antenna from which the mesh frame is transmitted, a first signal strength indicator value corresponding to the mesh frame, an unused radio and an unused channel of the second mesh network device. The processing device sends a first message to the unused radio of the second mesh network device on the unused channel via the second radio, receives a second message, and configures the multiple radios to communicate with the second mesh network device.

Abstract: Radio frequency (RF) front-end circuitry and methods of operating the same are described. One apparatus includes multiple antennas and a RF front-end circuitry. The RF front-end circuitry includes a first diplexer, a second diplexer, a third diplexer, a fourth diplexer, and a switch. A first transceiver is coupled to a first antenna via the first diplexer and the second diplexer. The third receiver is coupled to the first antenna via the first diplexer. The second transceiver is selectively coupled to a second antenna via the third diplexer, the switch, and the fourth diplexer when the switch is set to the first mode in response to the control signal from a processing component. The first transceiver is selectively coupled to the second antenna via the switch and the third diplexer when the switch is set to the first mode in response to the control signal from the processing component.

Abstract: An unmanned vehicle communicates with other unmanned vehicles. When the unmanned vehicle receives a message from another unmanned vehicle, the unmanned vehicle verifies authenticity of the message. For at least some types of messages, if determined that the message is authentic, the unmanned vehicle updates a set of operations the unmanned vehicle will perform in accordance with information in the message.

Abstract: Two unmanned vehicles come within communication range of one another. The unmanned vehicles exchange logs of messages each has received. Each of the unmanned vehicles analyzes the messages that it received from the other unmanned vehicle to determine whether any of the received messages warrants changing a set of tasks it was planning to perform. When a message indicates that a task should be changed, the task is updated accordingly.
