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 may pick, place, or move an item at an inventory location, such as a shelf. Described are techniques to determine a location of one or more of an object, such as an item or a user, with respect to an array of capacitive sensors. The array may be part of the shelf. As an item is added to, moved or removed from the shelf, when the user's hand is near the shelf, and so forth, capacitance measured by one or more of the sensors in the array may change. Based on these changes, a location relative to the sensor array may be determined. A particular shelf may have different areas, each designated as holding a different type of item. The location information obtained from the capacitive sensors may be used to determine which item on the shelf was interacted with.

Abstract: An apparatus includes a crossbar to which a plurality of accessories using different mechanical interfaces may be attached and detached. The crossbar is instrumented and provides information, such as a weight change due to addition to, or removal of, items from an accessory on the crossbar. An extensible bracket attaches the crossbar to a supporting structure, decreasing mechanical strain on the crossbar due to minor misalignment of the supporting structure. Accessories such as wire hooks, shelves, bins, and so forth may be supported by the crossbar. A tether device, locking cam device, or clip device may be used to prevent lateral movement of components such as the accessories or the entire crossbar relative to its supporting structure. A baffle may be affixed to the crossbar to constrain airflow for operation in a temperature-controlled case.

Abstract: A fixture includes a plurality of brackets. Accessories such as wire hooks, shelves, bins, and so forth may be supported by one or more brackets. A load cell supports each bracket and generates a signal that is indicative of changes to the bracket as items are added or removed from the accessory. The brackets include features such as tabs that prevent accessories from moving laterally. The fixtures are easily reconfigured to accommodate accessories of different sizes that in turn may support items of different sizes.

Abstract: One or more surfaces within a facility are equipped with devices having several segments, each segment with an antenna. Segments may be grouped together into a cluster. Each segment within a cluster is associated with a particular timeslot. A transmitter at the device transmits on a specific frequency. During the particular timeslot for that segment, a signal at the specific frequency is transmitted and radiated from the antenna for that segment. An object electromagnetically couples to one or more antennas of the device, acting as a signal path for the signal. A receiver in a second segment detects the signal, and information about the timeslot for the signal and relative signal strength is generated. By using this information, a location and path of the object may be determined. Receivers in shelves may also be used to facilitate disambiguation of one user from another when interacting with items on those shelves.

Abstract: A facility is equipped with floor tiles. Each tile is equipped with transmitters that transmit on specific frequencies. A particular set of frequencies identifies a particular floor tile and a particular segment on the floor tile. A user electromagnetically couples to one or more antennas of the tile, acting as a signal path for the signals on the particular set of frequencies. A receiver detects these signals, and the information about the frequencies detected and relative signal strength may be used to determine a location of the user within the facility. Receivers in the floor tiles allow a first tile to transmit its set of frequencies and a second tile to receive the set of frequencies and determine where the user has stepped from. By concatenating these steps a path of the user may be determined. Receivers in shelves facilitate disambiguation of one user from another when interacting with items.

Abstract: A platform is supported at four corners by four half-bridge load cells. Adjacent load cells are oppositely polarized. During operation, analog output from a pair of oppositely polarized half-bridge load cells is provided to an instrument amplifier. Analog output from the instrument amplifier is provided to an analog to digital converter to provide digital data. The digital data is then used to determine weight data indicative of a weight as measured by the pair of half-bridge load cells at that time. A set of switching elements, such as a quad bilateral switch controlled by a microcontroller, rapidly switch between pairs of oppositely polarized load cells. The weight data may be used to determine an overall weight change on the platform, such as a pick or a place of an item. Weight data from the four pairs of load cells may be used to determine a change in center of gravity.

Abstract: Fixtures can hold one or more items. Load cells may be used to measure the weight of the items on the fixture. In cases where items are added to or removed from the fixture, the load cells will detect a weight change at the fixture. Data reflecting the weight change is then used to determine interactions with the items on the fixture. However, vibrations to the fixture can introduce noise which can lead to inaccuracies in weight data acquired from the load cells. A vibration sensor can be used to measure the level of vibration detected at the fixture. Weight data acquired during a time interval when vibrations exceed a vibration threshold value is deemed invalid weight data. By contrast, weight data acquired when vibrations do not exceed the vibration threshold value will be deemed valid weight data that can be used for determining interactions with items at the fixture.

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.
