Abstract: Aspects of the disclosure are directed to a transactional agent for user interactions. The agent can seamlessly respond to user requests in a conversational manner while maintaining the conversational state. The agent can include a multi-stage modular model architecture, including a semantic understander and a semantic matcher. The semantic understander can be configured to understand common conversation conventions and/or patterns to produce a structure representation of a user request. The semantic matcher can be configured to map items and modifiers to product entries for a particular domain.

Abstract: Described is a system and method for routing output information to one or more of a plurality of output devices. In one implementation, output information that includes information to be presented and a location information identifying where the output information is to be presented may be generated by an output host. The output information is received by an output router that determines, based on the location information, an output device and routes the output information to the output device for presentation.

Abstract: Described is a system and method for developing and dynamically updating user paths through a materials handling facility. A user path through a materials handling facility may be developed that will route a user past one or more items (e.g., pick list items, recommended items, wish list items, promotional items) planned for the user. If the user does not follow the user path, the user path may be dynamically updated to account for the current location of the user and/or to consider other actions performed by the user.

Abstract: Described are systems and techniques configured to present information to a user of a facility that uses a wearable device. Using sensor data acquired from sensors in a facility, operational data associated with the user is generated. Such operational data may be related to providing customer assistance. The operational data is used to generate user interface data, which is transmitted to the wearable device. Upon receipt, the wearable device presents the operational data as a user interface using a display device, which may help provide customer assistance as needed.

Abstract: Described are systems and techniques configured to present information to a user of a materials handling facility storing items in inventory locations. A device such as a head-mounted display or a tablet computer is configured to provide an augmented reality user interface in which computer-generated data overlays objects in the real-world. The user interface may present information associated with assisting other users of the facility, operation of the facility, and so forth.

Abstract: A capsule pressure control assembly for regulating or controlling the internal pressure of filled capsules, whereby instances of capsule elongation are reduced or eliminated, thus resulting in an increased yield rate of acceptable filled capsules.

Abstract: This invention is a method (and an apparatus in combination) for sweep testing of cable television distribution systems and the like, wherein time division multiplexing between test signal and program signal is accomplished in such manner as to eliminate interference to the program signal due to testing. Additionally, the test signal received by the detector is time demultiplexed in such manner that the test signal is displayed clearly without interfering signals.

Abstract: Starch-thickened compositions containing particulate peroxygen compounds, especially diperazelaic acid, provide stable, effective compositions especially adapted for use as color-safe fabric bleaches at alkaline pH's, e.g., in laundry baths.

Abstract: Articles releasably containing starch-thickened peroxygen bleaches are provided.

Abstract: A mobile radio extension unit for converting a conventional mobile transceiver having a transmitter and a receiver to use as a repeater or transponder for establishing a bidirectional communications link between a transceiver of limited range and a base station or other mobile transceivers in the network. In a mobile communications system network having a plurality of extension units, associated mobile radios, and limited range transceivers, each extension unit includes means for automatically inhibiting multiple transmissions by units within range of one another and for providing punch through priority communications from a limited range transceiver to the base station or other mobile transceivers via one selected extension unit when the receiver associated therewith is repeating a communication to the transceiver.
