Abstract: Disclosed embodiments include a computer readable medium that may include instructions that when executed by one or more processing devices cause the one or more processing devices to perform a method. The method may include: identifying at least one reviewer-generated comment in an electronic document; based on analysis of the at least one reviewer-generated comment, generating one or more text output options each responsive to at least one aspect of the reviewer-generated comment; causing the one or more text output options to be displayed to a user; receiving an input from the user indicative of a selection of one of the one or more text output options; and automatically revising text implicated by the reviewer-generated comment in accordance with the selected one of the one or more text options.

Abstract: A system and methods for shopping checkout includes shopping carts, on which are affixed one or more shopping cart identification (ID) tags; a checkout counter that includes a payment register and a checkout processor, and a store exit that includes an exit ID tag reader, an exit processor, and an alert device. The checkout processor is configured to receive payment approvals from the payment register, to receive ID values of shopping cart ID tags, and responsively to generate shopping cart approval records. The exit processor is configured to determine ID values of shopping cart ID tags from output of the exit ID tag reader, to confirm whether or not the ID values correspond to the shopping cart approval records, and, if not to signal a lack of approval at the alert device.

Abstract: A method and system for determining locations of internet of things (IoT) tags are provided. The method includes receiving, during a predefined time window, packets from a plurality of gateways, wherein a received packets include at least sensing signals transmitted from the IoT tags; determining an affinity among the IoT tags based on the sensing signals; determining locations of IoT tags based on the determined affinity and the sensing signals, wherein a location of an IoT tag is a probability that an IoT tag is located in proximity to a gateway; and reporting the determined locations to a user terminal.

Abstract: 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.

Abstract: 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, wherein a downward force on the weight guard rail does not impose a downward force on the basket and is not indicated by the output signal provided by the scale, a user identification unit; and a payment module.

Abstract: A shopping cart includes a cart platform; a handle bar; wheels; a product scale; a basket resting on the scale independent of any support by the platform; and a user interface. The cart further includes a product sensor with a processor to read product information. The product scale, which weighs the products to ensure correspondence between the product price and its weight, is constituted merely by one or more transducers in operable contact with the basket.
