  • Patent number: 10481256
    Abstract: Example shopping cart corral systems and associated systems and methods are described. The example shopping cart corral system includes a corral structure, a radio-frequency transmitter, a radio-frequency receiver, and a controller coupled to the radio-frequency transmitter and the radio-frequency receiver. The controller estimates a quantity of shopping carts disposed in the shopping cart corral based on at least one property of the reflected radio-frequency signal. An example shopping cart counter system includes an elongated structure, first and second electrical contacts, a power source and a processing device. The power source applies a voltage or an electrical current to the first electrical contact and the shopping carts complete an electrical circuit between the first and second electrical contacts. The processing device estimates the quantity of shopping carts disposed in the elongated structure based on an electrical resistance associated with the shopping carts.

    Abstract: A method of processing documents by receiving at least a batch of documents and a separator card in an input receptacle of a document processing device. The separator card includes a conductive material disposed on one side, and a barcode indicative of the source of the batch of documents. The documents and separator card are transported via a transport mechanism past an evaluation unit and a field-effect sensor, respectively. The document processing device evaluates each document, determines whether the document meets or fails predetermined criteria, and detects the presence of the conductive material when a separator card is transported past the sensor. The source identification information from each separator card is entered into a memory of the document processing device after all the documents from the corresponding batch of documents have met the predetermined criteria. Feeder operation is paused between each batch long enough to verify that the previous batch closed successfully.
