    摘要： Network hardware devices organized in a wireless mesh network (WMN) in which one network hardware devices includes a first radio and a second radio coupled to a processing device. The processing device receives a request from a client consumption device via the first radio and determines a destination for the request as a second mesh network device. The processing device access a master routing table to determine that the second radio is to forward the request and forwards the request to the second radio. The second radio accesses a local routing table at the second radio to determine that a radio of a third mesh network device is a next-hop mesh network device in a first path to the second mesh network device. The second radio sends the request to the radio of the third mesh network device.

    摘要： Technology for a bi-directional radio frequency front-end (RFFE) architecture with high selectivity performance is described. One RFFE has a first mixer that receives a LO signal from the LO circuit and a transmit (TX) signal, having a first frequency, from a transmitter and produces a down-converted TX signal for channel bandwidth filtering, the TX signal having a second frequency that is lower than the first frequency. A programmable filter circuit, in response to a selection signal, filters the down-converted TX signal according to a selected channel bandwidth. The second mixer receives the LO signal from the LO circuit and a channel-filtered TX signal from the programmable filter circuit and produces an up-converted TX signal having the first frequency. The power amplifier amplifies the up-converted TX signal to produce an output TX signal to cause an antenna to radiate electromagnetic energy in the selected channel bandwidth.

    摘要： A wearable computing device, such as a wearable credit card type device or a wearable identification type device, that provides for deferred re-authentication that a user currently in possession of the wearable computing device is indeed the authorized user. In this aspect, the wearable computing device may store authentication data input by the user when network connection is unavailable, and transmit the authentication data when the network becomes available. For increased security, location information may also be incorporated so that the re-authentication may only occur within a limited number of geographic locations.

    摘要： 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.
