The roadway management system can also generate updates to the vehicle state based upon data obtained from sources external to autonomous vehicles.

Abstract: Systems and methods are provided herein for providing item information via a network page of an electronic marketplace. A set of items associated with a potential order of an electronic marketplace may be obtained. The set of items may be associated with a threshold condition that must be met prior to enabling completion of the potential order. Item information associated with the set of items, electronic representations of a portion of a plurality of related items, and a remainder value may be displayed on a network page provided by a mobile device. The remainder value may indicate a difference between a current state of the set of items and the threshold condition. A request to associate a related item of the plurality of related items with the potential order may be received. The set of items may be updated and the remainder value may be modified based on the update.

The input surface may include a plurality of RFID transmitting devices provided on at least one flexible layer, and the input station may include one or more RFID receiving devices, e.g., antennas and/or readers, provided in communication with a computing system or network. A worker may contact one or more portions of the input surface, and thereby cause one or more of the RFID transmitting devices to transmit one or more RFID signals including information, data, commands or instructions to be provided to the RFID receiving devices. Audible, visible or haptic feedback may be provided to the worker in response to the transmission of the one or more RFID signals.

Abstract: An RFID device may include one or more manually activated RFID tags configured to transmit unique RFID signals in response to a manual activation thereof. A transaction may be defined upon receiving a confluence of multiple RFID signals at the same time, or at nearly the same time, at an RFID reader. A transaction may also be defined upon receiving multiple RFID signals or confluences of such signals in a predetermined series or sequence. The RFID devices may include a single manually activated RFID tag, or two or more of such tags, which may be individually activated by one or more manual interactions from a user.

Abstract: Disclosed are various embodiments for making ordinary objects network-enabled interfaces. A radio-frequency identification (RFID) tag may be fixed or detachably attached to an item capable of being manipulated by a person to obtain information about the item or to cause a performance of a task associated with the item. The RFID tag may include a capacitive touch interface that, when manipulated by a person, causes the RFID tag to emit an identifier associated with a corresponding item. A receiver, having the identifier and an instruction from a person, may communicate with a remote computing device to process the instruction and to generate a response to the instruction.

Abstract: An inventory system can include radio frequency identification (RFID) tags and RFID tuners that can be brought into interacting proximity with one another to provide input or other information about the location or other condition of movable elements within the inventory system. A wearable accessory that is wearable by a human operator can include RFID tuners thereon for interacting with RFID tags on other elements of the inventory system in order to communicate details about the elements and facilitate functions of the inventory system.

Abstract: Aspects of tag-based product monitoring and evaluation are described. In one embodiment, a system directs a tag reader to interrogate an RFID tag provided on a product package for a product. In response, the system receives a unique identifier, product detail data, and product usage data from the RFID tag. In certain cases, the system can place an order for the product on an electronic commerce platform based on the unique identifier, the product detail data, and the product usage data. For example, the system can identify when the product package was opened with reference to the product usage data, determine that the product is expired based on when the product package was opened, and place the order for the product based on the product being expired.

Abstract: In some examples, a reader system is provided for managing inventory items in an inventory system. The reader system may be configured to read tags associated with items stowed in an inventory holder. The inventory holder may be detachably coupled to a mobile drive unit. The mobile drive unit may move the inventory holder to a first position near an antenna of the reader system and the tags may begin to be read. While reading or at other times in the reading process, the mobile drive unit may move the inventory holder relative to the antenna. The identified tags may be compared to a manifest list of items expected to be stowed in the inventory holder.

Abstract: An inventory system employs self-illuminating inventory management containers. A self-illuminating container can include a container body, an illumination element, and a signal receiver for receiving instructions to illuminate the container. The self-illuminating inventory management containers can be illuminated to assist in locating the containers in the system broadly, or locally, and to assist in inventory processing operations.

Abstract: In some examples, a mobile reading device is provided. The mobile reading device may include an movement device and a reader device. The reader device may be configured to read, via one or more antennas, identifying tags associated with items. The one or more antennas may be included as part of the mobile reading device, within a holder structure, or in some other structure or device.

Abstract: A reader system and an imaging device are provided. The reader system is configured to read a tag attached to an item at a location relative to a barcode. The barcode is associated with the item. Once the reader system identifies the tag, the imaging device uses the placement of the tag and/or features of the tag to identify and read the barcode. The imaging device may also identify the tag. Once the barcode is identified, the barcode and the tag are associated.

Abstract: A wearable RFID device may include one or more manually activated RFID tags configured to transmit unique RFID signals in response to a manual activation thereof. Such wearable RFID devices may be worn about any aspect of a user's body, such as a hand, a wrist or an arm of the user, who may contact the manually activated RFID tag and transmit an RFID signal that is consistent with a particular action or instruction associated with a task. The action or the instruction may be executed based on the RFID signal, or upon receiving a confluence or sequence of RFID signals. Additionally, a wearable RFID device may be recognized by one or more discrete systems and configured to operate such systems accordingly.

Abstract: Where a safety requirement mandates contact with a grippable structural element such as a handle, a handrail, a handlebar or a steering wheel, compliance with the requirement may be determined using one or more manually activated RFID tags provided in designated locations on the grippable structural element. A level of compliance with the requirement during a given activity may be determined based at least in part on the number of RFID signals received from the manually activated RFID tags, which may be compared to a number of workers engaged in the given activity. Based on the level of compliance, relevant feedback in the form of electronic messages, signals or sounds may be identified and provided to one or more of the workers.
