Disclosed is an electric range controlling heat power based on properties of a heating target. The electric range may adjust the heat power based on the properties of the heating target, when a user makes a gesture of moving the heating target in a specific direction. A unit decrease amount value of the heat power sequentially decreasing may be set based on the information related to the heating target. The information related to the heating target may include at least one of the weight of the heating target, the size of the bottom surface of the heating target or the property of contents contained in the heating target.

The present invention relates to a luggage scale device. A housing of the device can be attached to a wall via a fastener, wherein a weighing member can then be extended perpendicular to the housing. The strain gauge load cell is positioned on the member and allows luggage to be weighed via placing a strap of the luggage on the member such that the device suspends the luggage above the ground. The weight of the luggage is then displayed via a display on the housing.

A wireless scale apparatus can include a housing having one or more receiving portions formed therein, a printed circuit board (PCB) having a microprocessor coupled therewith, the PCB operably coupled with a power source, an antenna, and a load cell, wherein the microprocessor is operable to determine a load received upon the load cell.

A method for addressing a shopper's eligibility for frictionless checkout may include identifying at least one shopper in a retail store designated as not eligible for frictionless checkout; in response to the identification of the at least one shopper designated as not eligible for frictionless checkout, automatically identifying an ineligibility condition associated with the at least one shopper's designation as not eligible for frictionless checkout; determining one or more actions for resolving the ineligibility condition; causing implementation of the one or more actions for resolving the ineligibility condition; receiving an indication of successful completion of the one or more actions; and in response to receipt of the indication of successful completion of the one more actions, generating a status indicator indicating that the at least one shopper is eligible for frictionless checkout and storing the generated status indicator in a memory.

Disclosed is a mobile robot configured to cut lawn in a work area. The mobile robot may include a main body, a weight sensing sensor, an obstacle sensing sensor, a blade, and a processor. The mobile robot may execute an artificial intelligence (AI) algorithm and/or a machine learning algorithm, and perform communication with other electronic devices in a 5G communication environment. As a result, it is possible to enhance user convenience.

Systems and apparatuses for safety deposit box access using a smart table and a locker are described herein. A safety deposit box access system includes a smart table and a locker. The smart table includes a processing circuit configured to receive an appointment request from a customer user device. The processing circuit is further configured to authenticate the customer, verify the customer is authorized to access the safety deposit box, release the safety deposit box from the locker, measure the change in weight of the safety deposit box, lock the locker, and transmit a notification to the customer when the safety deposit box has been returned to the vault.
