A shopping cart and method of autonomous shopping are provided including a cart chassis, a scale configured to rest on base of the chassis, a basket resting on the scale, wherein weights of products placed in the basket are indicated by the output signal of the scale, a weight guard rail positioned above the product basket and attached to the cart chassis, a user identification unit, a payment module, and a motion sensor.

A wearable payment device, such as a finger ring worn by a user, communicates payment data to a payment reader that uses the payment data in order to request a payment transaction. Such wearable payment device may be conveniently carried by and accessible to the user such that utilization of the payment device for the payment transaction is less burdensome for the user, thereby encouraging use of the payment device for payments. Indeed, in some cases, such as when the payment device is implemented as a finger ring or other type of jewelry, the user may be encouraged to carry the payment device in an exposed manner such that it is readily available for the payment transaction without the user having to search in a wallet, pocket, or purse.

An electronic device such as a wearable electronic device may have a coil. The device may have a finger-ring housing that surrounds a finger-shaped opening to allow the device to be worn on a finger of a user. The coil may be formed from metal traces on a printed circuit that wrap around the finger-shaped opening. Near-field communications circuitry in the device may be used to gather near-field communications tag information. The tag information may be gathered in response to user input. Wireless communications circuitry that uses a non-near-field communications antenna may wirelessly transmit the tag information and/or other information such as user input to a companion device.

A system and method for tracking marine equipment is provided. Generally, the system and method of the present disclosure are designed to generate indicia corresponding to the inventory level of marine equipment used for a particular marine activity. To facilitate the assignment of indicia reflecting the inventory level of marine equipment used for a marine activity, the system and method of the present disclosure uses a plurality of equipment profiles having a defined lower limit and quantity associated with each piece of marine equipment. The lower limit may be manually input or automatically generated. The quantity may be tracked by the system using equipment transmitters and equipment sensors. In a preferred embodiment, the indicia indicate whether the quantity of a piece of marine equipment has fallen below a certain specified level as defined by the user. Users may purchase new marine equipment from third-party retailers via the user interface.

An autonomous or semi-autonomous vehicle fleet comprising a plurality of autonomous or semi-autonomous vehicles for providing an assortment of items to a customer or a potential customer after such customer or potential customer summons the one or more autonomous or semi-autonomous vehicles in an unstructured open or closed environment. Each autonomous or semi-autonomous vehicle comprises one or more compartments configured to contain and secure the assortment of the items to be selected once the summoned autonomous or semi-autonomous vehicle arrives to a customer or potential customer.

A container includes a surface defining a volume of the container, a first resonance portion disposed on a first portion of the surface of the container using one or more first carbon-based inks, and a second resonance portion disposed on a second portion of the surface of the container using one or more second carbon-based inks different than the one or more first carbon-based inks. The first resonance portion can resonate within a first range of frequencies in response to one or more electromagnetic pings received from a user device, and the second resonance portion can resonate within a second range of frequencies in response to the one or more electromagnetic pings, the second range of frequencies being different than the first range of frequencies. In some instances, the user device may be a smartphone, a radio frequency identification (RFID) reader, or a near-field communication (NFC) device.

Provided is a user interface for both event generation and participation.

An event management system includes: an API database that stores an event execution management API and a resource management API; an event database that stores an event execution program and log data; an API registration processing unit; an event generation processing unit; an event registration processing unit; and a communication processing unit. The event management system treats a module as a nested scenario; uses a time zone and a field zone, a transition arrow, an icon, and a descriptor; interprets, in a completed chart diagram, a structure of the time zone, field zone information, an inclusion relationship of contents and a descriptor with respect to the time zone, portion arrangement information of contents and the descriptor on another icon, and a connection relationship of a transition arrow; generates an analysis structure to set as a structure unique to a chart and a module; and realizes chart interpretation equivalent to programming in a markup language.

A method includes processing, by a processing module of a data logging device, a plurality of log commands. The processing of a log command of the plurality of log commands includes obtaining a measure of an environmental condition. The processing further includes updating a status of the environmental condition based on the measure of an environmental condition. The method further includes determining, by the processing module, the updated status of the environmental condition after the plurality of log commands have been processed. When the updated status of the environmental condition is favorable, the method further includes generating, by the processing module, a favorable environmental condition signal.

A data logging device includes an activation circuit, an environmental sensor, a processing module, and an environmental indicator. The activation circuit is operably coupled to place the data logging device in a ready mode based on an activation signal. The environmental sensor is operable to sense an environmental condition associated with the data logging device in response to a log command to produce sensed data. The processing module is operably coupled to generate the log command; receive the sensed data; determine whether the sensed data triggers an environmental violation; and, when the sensed data triggers the environmental violation, generate an environmental violation signal. The environmental indicator is operably coupled to provide a visual indication of the environmental violation based the environmental violation signal.
