Abstract: A floor device generates output data indicative of the presence of objects, such as feet of users, on the floor device. The output data from the floor device is processed to determine an object representation at a given time. The object representation may then be associated with a user identifier based on characteristics or features of the object representation. If a location of a user associated with the user identifier is determined to be near a fixture that stores one or more items, changes in quantity of items at the fixture may be associated with the user. For example, sensors on the fixture may generate fixture data indicative of a pick or place of items on the fixture. Based on the location of the user being near the fixture and the fixture data, interaction data may be generated indicating the user interacting with the items at the fixture.

Abstract: A facility is equipped with floor tiles, each tile having several segments, each segment with an antenna. Each segment on a tile is associated with a particular timeslot. A transmitter at the tile 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. A user electromagnetically couples to one or more antennas of the tile, acting as a signal path for the signal. A receiver in a second tile detects the signal, and information about the frequency detected, timeslot for the signal, and relative signal strength is generated. Where the user has stepped from is determined using the information. 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 tamper detection system utilizes a barrier that includes a bar sized to extend across a rack in an arrangement in which the bar blocks access to an appliance received in the rack. The tamper detection system further utilizes a detector configured to log, transmit, or otherwise generate an indication that the barrier has been tampered with, such as in response to the bar being pulled away from the rack enough to decouple a magnet that when magnetically coupled to the rack maintains a switch in a first state against a biasing force of a biasing mechanism urging the switch toward a second state, or such as in response to the bar becoming severed or pulled away from the rack enough to cause a detectable change of resistance or other electrical characteristic in a corresponding circuit.

Abstract: A storage unit includes a support bar for hanging items and an RFID antenna provided within a predefined distance of the support bar. When the items hanging from the support bar are adorned with RFID tags, and the RFID antenna emits electromagnetic fields in a direction of the support bar, RFID signals identifying the items are transmitted from the RFID tags to the RFID antenna, thereby enabling a placement or a removal of an item to be automatically registered, or an accounting of the available items to be automatically performed. The RFID antenna may be a portion of a transmission line that uses shields and/or dielectric materials to shape the electromagnetic fields toward a predefined direction, and the locations of items bearing RFID tags on the support bar may be determined by varying the phase of the emitted radiofrequency and determining strengths of RFID signals when the electromagnetic fields are emitted at varying phases.

Abstract: A facility monitoring system and/or a secure data storage device transport trolley accounts for data storage devices removed from rack computing devices while in transport. The secure data storage device transport trolley comprises a backplane, backplane connectors, and a computing device coupled to the backplane. The computing device scans for data storage devices connected to the connectors of the backplane at regular intervals and maintains an updated list of data storage devices being transported by the secure data storage device transport trolley. The secure data storage device transport trolley also provides the list to a facility monitoring system for reconciliation.

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: An entry portal to a facility may include radio receivers with directional antennas and cameras at known positions in the facility. The receivers acquire device identifier and device data from a mobile device carried by a user passing through the portal. Portal data is generated that is indicative of the coverage volume of a particular antenna that received a signal carrying the device identifier and signal strength of that signal. The cameras acquire images of the user. Other sensors may acquire other information included in the portal data. The portal data, device data, device identifier, and the images are processed to associate a particular account with a person passing through the entry portal. Subsequently, that person may then be tracked using images from other cameras in the facility.
