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.

Image-based item detection and allocation

This disclosure describes a system for disambiguating between multiple potential users that may have performed an item action (e.g., item removal or item placement) at an inventory location. For example, if there are three picking agents (users) standing near an inventory location and one of the agents removes an item (item action) from the inventory location, the example systems and processes described herein may utilize various inputs to disambiguate between the users and determine which of the potential users performed the item action.

Disambiguating between users

Item detection and transitions

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.

Systems, methods, and apparatus are provided for enabling orientation of directional antennas even when one or more of the directional antennas are moving. Position information for each directional antenna is transmitted using an omnidirectional antenna transmitting at a low bandwidth and a low power. The position information of the directional antennas is used to orient the directional antennas so that a high bandwidth, low power wireless connection can be enabled and/or maintained between the directional antennas. The position information is periodically transmitted and the orientation of the directional antennas is updated as one or more of the directional antennas move so that the wireless connection between the directional antennas is maintained.

Agent identification and disambiguation

Wireless mesh network (WMN) architectures of network hardware devices organized in a mesh topology 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 is described. A self-contained, fully connected WMN can be used for localized delivery of content files. One WMN includes a single ingress node for ingress of content files into the wireless mesh network. The WMN also includes multiple network hardware devices wirelessly connected through a network backbone formed by multiple P2P wireless connections. A first network hardware device is wirelessly connected to a client consumption device by a first node-to-client (N2C) wireless connection and a second network hardware device is wirelessly connected to the single ingress node.

A system includes a platform including a first mounting component and a second mounting component, the platform being secured to an external surface of a structure via the second mounting component, a first network device coupled to the first mounting component, the first network device being part of a first network, and a second network device coupled to a surface of the platform and communicably coupled to the first network device. The system may further include an energy source component configured to provide power to the first network device, wherein the second network device is configured to receive data from the first network device and provide the data to one or more client devices located within the structure.

Mounting platform for network devices in a reconfigurable network

Network hardware devices organized in a wireless mesh network (WMN) in which a home access node (HAN) device that includes a first set of radios, each of the first set of radios being coupled to a beam-steering antenna and each of the first set of radios establishing a first point-to-point (PtP) wireless connection over which the HAN relay device communicates with a second HAN relay device in a first sub-mesh network of HAN relay devices. The HAN device also includes a second set of radios, each of the second set of radios being coupled to a beam-steering antenna and each of the second set of radios establishing a second PtP wireless connection over which the HAN relay device communicates with at least one of a plurality of HAN devices in a second sub-mesh network in the WMN.

Wireless mesh network for broadband connectivity

Network hardware devices are organized in a wireless mesh network (WMN) including multiple home access node (HAN) relay devices located in a geographic area and separated from one another by a distance. To avoid an obstruction preventing terrestrial line-of-sight (LOS) communications, an aerial reflector is deployed for terrestrial non-line-of-sight (NLOS) communications between first and second HAN relay devices. The aerial reflector device is positioned at an aerial location above a first terrestrial location of the first HAN relay device and a second terrestrial location of the second HAN relay device. The aerial reflector device includes a reflective surface that is positioned and oriented to provide terrestrial NLOS communications between a radio of the first HAN relay device and a radio of the second HAN relay device.
