Abstract: A surface within a facility, such as a floor, is equipped with electromagnetic sensors that generate data indicative of the presence of objects, such as the feet of users, at or close to the floor. The data may also be indicative of cross-coupling resulting from a transfer of an electromagnetic signal by the object, such as from one foot to another of a user. The data is processed to determine presence of individual object representations, such as representing a foot. Information about object representations such as their movement, cross-coupling, physical distance between, or features of the object representation may be determined. This data may be used to maintain the identity of particular object representations, track object representations over time, determine that particular object representations are associated with a single user and so forth. Adjacent object representations may avoid merging by using a top-down cross sectioning technique.

Abstract: Described is a system and method for efficiently tracking inventory using RFID tags (e.g., RFID tags). For example, an RFID tag reader may perform an inventory mode to receive RFID tag identifiers from RFID tags located within a range of an antenna element of the RFID tag reader. Those RFID tag identifiers may be included on an inventory table associated with the antenna element. In a second mode, the RFID tag reader may perform a targeted read. During a targeted read mode, the RFID tag reader, utilizing the antenna element, may issue a request for a selected RFID tag identified in the inventory table to reply to the request.

Abstract: Image-based object representation (OR) tracking of users or other objects in a facility may occasionally lose the identity associated with a particular OR. For example, in a crowded aisle the respective ORs for individual users may merge, resulting in a loss of identity of the particular OR. As the crowd dissipates, confidence in the identity of a particular OR may be low. In one implementation, image processing is used to determine OR movement data descriptive of the time(s) when the OR is in motion or stopped. Device movement based on data acquired by sensors on a mobile device carried by a user is descriptive of when the mobile device is in motion or stopped. A match between the particular OR movement data and the particular device movement data allows the identity of the particular OR to be determined as an identity associated with the mobile device.

Abstract: A fixture includes a shelf upon which items may be placed. In one implementation, the shelf is supported by four load cells that provide load cell data that may be used to calculate weight data for the load on the shelf. The load cells are mounted underneath a frame, with an upper portion of a load mount extending upward through the frame and engaged to the shelf. The shelf and the frame include stiffeners to increase rigidity, improving the quality of the load cell data. Electronics and a wiring harness are located underneath the frame. In this configuration, assembly of the fixture may be accomplished completely from the underside, simplifying assembly.

Abstract: Capacitive sensors may be used to gather information, such as the presence of objects at an inventory location, such as a shelf. Two or more adjacent capacitive sensors operating at the same time may interfere with one another. Described are techniques to prevent this interference by using seed values to initialize pseudo random sequencing of an order in which capacitive sensors are in operation. The capacitive sensor, or a portion thereof, may be also be used as an antenna. Selection of an initial tuning network for use by the antenna may be determined based on output from the capacitive sensor.

Abstract: Sensors at an inventory location can be used to detect the occurrence of an event at the inventory location. For example, capacitive sensors can gather capacitance values, which can then be analyzed for changes that indicate an event has occurred at the inventory location. When an event has been detected, event data is generated and used as a possible trigger to collect additional sensor data. As an example, if an event involving items at an inventory location is detected, such an action can trigger the collection and analysis of additional sensor data, such as weight sensor data, to determine a quantity of the items added or removed from the inventory location.

Abstract: A facility may include antennas directed to a known location and cameras with a field-of-view that encompasses the known location. The antennas acquire a device identifier and device data from a mobile device carried by a user at the known location. Antenna data is then generated to describe the data acquired by the antennas. Image data is also generated from the cameras to include images of a person at the known location. The antenna data and image data are then processed to determine estimated motion values and a comparison of such values is performed to check if such motion values are within a threshold of one another. If the motion values are within a threshold of each other, data indicative of presence of the mobile device at the known location is generated.

Abstract: Objects in a facility, such as users or totes, may be tracked as the object moves within the facility. An object representation of the object may be detected using image data. Apparent motion of the object representation may also be detected based on changes within the image data over time, which can help determine movement data for the object representation. However, the identity of the object representation may not be known. Using data from motion sensors in a device, movement data for the device can be generated. Thereafter, the movement data determined using the image data and the movement data determined using the data from the motion sensors in the device are compared for a possible match. If a match is found, an identifier of the device may then be associated with the object representation in the image data for tracking purposes.

Abstract: A user obtains authentication credentials using a portable device, such as a smart phone. While standing on a smart floor in a facility, the portable device transmits the authentication credentials to the smart floor. The body of the user electromagnetically couples to electrodes in a touch sensor of the portable device and one or more antennas of the smart floor, acting as a signal path for signals between the mobile device and the smart floor. For example, one or more of the voltage applied to the electrodes, timing of when voltage is applied, and so forth, may be used to produce a particular electromagnetic signal that conveys the authentication credentials. The authenticated user may now be tracked in the facility using the smart floor.

Abstract: This disclosure describes the ability to efficiently track inventory using RFID tags (e.g., RFID tags). For example, an inventory shelf located within a materials handling facility may include a series of antenna elements arranged in rows embedded into the shelf that are coupled with an RFID reader. The antenna elements are configured to establish electromagnetic fields oriented along shelf rows. The fields can be used to read RFID tags included or attached to inventory items placed on the shelf row.
