    Abstract: A method includes: transmitting, by a first radio frequency transceiver of a first device, a first signal; receiving, by the first radio frequency transceiver of the first device, a second signal in response to the first signal; determining a time value associated with the receiving of the second signal; determining that at least one of the time value or a distance value determined using the time value is less than or equal to a first threshold value, wherein the first threshold value is associated with the first device; and triggering a first output by a user interface component of the first device based on at least one of the time value or the distance value being less than or equal to the first threshold value.

    Abstract: Systems and methods for detecting an event within a monitored area are provided. A transmitter emits an RF interrogation signal into the monitored area. An RF target positioned within the monitored area reflects the interrogation signal as a target signal when the interrogation signal impinges on the RF target. The RF target has a switch actuatable by a user between a switch-state in which the RF target operates in a first reflective state, and a switch-state in which the RF target operates in a second reflective state. A receiver receives the target signal from the RF target. Based on the target signal received by the receiver, a processor can detect an indication of the reflective state in which the RF target is operating. The processor triggers an action in response to the indication of the reflective state in which the RF target is operating.

    Abstract: Provided are architectures, systems, methods, and computer program products for real-time object locating and position determination using frequency channel diversity for transmitting and receiving position determination signals including bursts of location signals. Channelized frequency diversity of a short burst of small location signals that “hop” across multiple frequency channels is used to collectively produce a quasi-wideband position determination signal. Object tags operating with frequency channel diversity for transmitting location signals of position determination signals require low power consumption, but can still efficiently provide adequate position determination signals for reliable position determination.

    Abstract: A method of generating dimensioning assist information for an item includes: obtaining data associated with a physical size of a graphical dimensioning aid associated with the item; generating dimensioning assist information by encoding the data into a machine-readable data object carried by the item. A method of dimensioning an item includes, at a dimensioning system: capturing an image of the item and the graphical dimensioning aid carried by the item; detecting an edge of the item within the captured image; determining a measurement of the edge; detecting the graphical dimensioning aid within the captured image; determining a measurement of the graphical dimensioning aid; decoding a physical size of the graphical dimensioning aid from a machine-readable data object carried by the item; and dimensioning the edge based on the measurement of the edge, the measurement of the graphical dimensioning aid, and the physical size.

    Abstract: A method includes: obtaining an item identifier corresponding to an item for placement in a container, the item being associated with a delivery destination; in response to placement of the item at a storage position within the container, recording a storage location including coordinates of the storage position; monitoring transit information of the container during transport of the container; when the transit information of the container corresponds to the delivery destination, retrieving the recorded storage location of the item within the container; and controlling an output assembly to generate item retrieval guidance based on the recorded storage location.

    Abstract: An example method includes determining that first locations of a first location tag and second locations of a second location tag indicate that the first location tag is moving at a different rate than the second location tag; and, in response to determining that the first and second locations indicate that the first location tag is moving at a different rate than the second location tag at a first time, determining a distance magnitude between the first location tag and the second location tag at the first time; comparing the distance magnitude to a reference distance; and determining, based on the comparing of the distance magnitude to the reference distance, whether the first and second locations indicate that a type of movement of an asset is rotational.
