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.

Abstract: Network hardware devices organized in a Wireless mesh network (WMN) in which the network hardware devices cooperate in distribution of content files to client consumption devices in an environment of limited connectivity to broadband Internet infrastructure are described. One mesh network device includes a micro controller, RF radios, and antenna switching circuitry. The antenna switching circuitry, in response to the control signals from a micro controller, selectively couples individual ones of a first set of antennas to individual channels of the set of RF radios to communicate content data with client consumption devices and selectively couples individual ones of a second set of antennas to other individual channels of the set of RF radios to communicate content data with other mesh network devices in a WMN.

Abstract: An unmanned vehicle determines how to perform a task based at least in part on a message received from another unmanned vehicle. At a later time, the unmanned vehicle detects that the other unmanned vehicle has become untrusted. The unmanned vehicle recalculates how to perform the task such that the recalculation is independent of any messages from the other unmanned vehicle. The unmanned vehicle may also transmit messages to other unmanned vehicles to provide notification of untrustworthiness of the other unmanned vehicle.
Abstract translation: 至少部分地基于从另一无人车接收到的消息，无人驾驶车辆确定如何执行任务。 以后，无人驾驶车辆检测到其他无人驾驶车辆已经不受信任。 无人驾驶车辆重新计算如何执行任务，使得重新计算独立于来自其他无人驾驶车辆的任何消息。 无人驾驶车辆还可以向其他无人驾驶车辆发送消息，以提供其他无人驾驶车辆的不可信度的通知。

Abstract: A user device transmits data at a first transmit power level. The user device detects a presence of a human body part within a predetermined distance from an antenna of the user device using one or more sensors disposed at a back side of the user device. In response to the detection of the presence of the human body part, the user device transmits information at a second transmit power level that is less than the first transmit power level.

Abstract: This disclosure describes a distributed automated mobile vehicle (“automated mobile vehicle”) system for autonomously delivering orders of items to various delivery locations and/or autonomously returning items to a return location. In some implementations, each user may own or be assigned their own automated mobile vehicle that is associated with the user and an automated mobile vehicle control system maintained by the user. When the user orders an item, the user owned or controlled automated mobile vehicle navigates to a materials handling facility, retrieves the ordered item and delivers it to the user.

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.
