Abstract: This disclosure describes, in part, systems for enabling physical retail stores and other facilities to implement automated-checkout techniques for the purchase of items that are priced per unit weight. For example, the described systems may enable a facility to implement technology where users are able to remove items from inventory locations, where the inventory locations include weight sensors detecting the weights of the items that were removed. The system then determines the prices based on the weights and charges the users for the prices of the items without performing manual checkout of the items. The price of an item is determined based on the weight of the item and the price per unit weight of the item. The systems described herein thus enable customized retail facilities, as opposed to a retail facility that allows automated-checkout only for prepackaged-type or otherwise non-customizable merchandise.

Abstract: This disclosure describes, in part, systems for enabling physical retail stores and other facilities to implement automated-checkout techniques for the purchase of items that are priced per unit weight. For example, the described systems may enable a facility to implement technology where users are able to remove items from inventory locations, place the items on weight sensors, and then be charged for the prices of the items without performing manual checkout of the items. The price of an item is determined based at least in part on the identifier of the item and the price per unit weight of the item. The systems described herein thus enable customized retail facilities, as opposed to a retail facility that allows automated-checkout only for prepackaged-type or otherwise non-customizable merchandise.

Abstract: A sensor for sensing ions, comprising a circuit board assembly, and a core assembly connected to the circuit board assembly, the core including a first electrical conductor and a second electrical conductor.

Abstract: A sensor for sensing ions, including a circuit board assembly, a core, a cage at least partially surrounding the core, a first wire wrapped around the core and connected to the circuit board assembly, a second wire wrapped around the core and connected to the circuit board assembly, and a third wire connecting the cage to the circuit board assembly.

Abstract: A fluid application system includes a diluent reservoir, a chemical container, a sprayer housing, a manifold located in the sprayer housing, and a pump assembly in fluid communication with an outlet of the manifold. The manifold includes a diluent inlet in fluid communication with the diluent reservoir, a chemical inlet in fluid communication with the container, a mixing chamber in fluid communication with the diluent inlet and the chemical inlet and the outlet of the manifold. The pump assembly draws a mixture of the chemical and the diluent from the manifold and sprays the mixture of the chemical and the diluent from the nozzle.
