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: 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: An item-providing system supplies items to a user device for consumption at the user device via communication infrastructure. In one representative implementation, a user device includes a mode switching wireless communication module. The mode switching wireless communication module is adapted to receive a first paging signal via a first communication protocol when in a first mode of operation and adapted to receive a second paging signal via a second communication protocol when in a second mode of operation. The user device also includes a to-do list processing module. In response to receiving one of the first or second paging signal, the to-do list processing module sends a request to a remote network device. The request requests that one or more instructions be sent from the remote network device.

Abstract: 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.

Abstract: A system and method for controlling access to digital content based on proximity and location of a user device. A user device connects to a local network and an audio transmission including a perpetually rolling key is transmitted within a geo-fence in the local area. The user device hears the audio transmission and uses the key to authenticate to a content server over the network. Once authenticated, the user device may then stream content from the content server. In order to terminate access to the content when the user device leaves the geo-fence, the content server may require the key to be retransmitted from the user device at regular intervals to re-authenticate the user device. Other factors such as radio fingerprints from the user device may also be used instead of or in addition to the audio to verify the user device's presence within the geo-fence.
Abstract translation: 一种用于基于用户设备的接近度和位置来控制对数字内容的访问的系统和方法。 用户设备连接到本地网络，并且包括永久滚动密钥的音频传输在本地区域内的地理围栏内传输。 用户设备听到音频传输，并使用密钥通过网络向内容服务器进行身份验证。 一旦认证，用户设备然后可以从内容服务器流传输内容。 为了在用户设备离开地理围栏时终止对内容的访问，内容服务器可能需要定期从用户设备重传密钥以重新认证用户设备。 也可以使用诸如来自用户设备的无线电指纹的其他因素来代替或补充音频，以验证用户设备在地理围栏内的存在。

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: A processing device receives network data from a plurality of user devices. The network data identifies networks available to provide roaming service to at least one of the plurality of user devices at one or more geographical locations. The processing device generates at least one list of identifiers of preferred networks for at least one of the geographical locations based on the network data. The processing device sends the list of identifiers to the plurality of user devices.
