Abstract
A system includes a structure configured to hold items, at least one capacitive touch sensor, and an item scanner configured to move the capacitive touch sensor relative to the structure and to identification elements disposed on the items held by the structure. Each identification element represents a multi-digit code. The capacitive touch sensor is configured to generate a sensor signal comprising sequences of waveforms in response to movement of the capacitive touch sensor relative to the identification elements. Each sequence of waveforms includes the multi-digit code that identifies one of the items.
Claims15
A system comprising:
- a structure configured to hold a plurality of items;
- at least one capacitive sensor;
- and
- an item scanner configured to generate a sensor signal when the item scanner scans the items, wherein the sensor signal is generated in response to relative movement between the at least one capacitive sensor and identification elements disposed on the items held by the structure, each identification element representing a multi-digit code, wherein the capacitive sensor touches the identification elements during the relative movement, and further wherein the item scanner is further configured to scan the items in response to a trigger comprising a signal from a sensor that senses that an item has been removed from the structure or placed in the structure;
- wherein the sensor signal generated by the item scanner when the item scanner scans the items comprises sequences of waveforms, each sequence of waveforms includes the multi-digit code that identifies one of the items.
A method comprising:
- in response to a trigger comprising a signal from a sensor that senses that an item has been removed from a structure or placed in the structure, scanning items held on the structure by causing relative movement between a capacitive sensor and identification elements disposed on items held on a structure, each identification element representing a multi-digit code, wherein the capacitive sensor touches the identification elements during the relative movement;
- and
- in response to relative movement between the capacitive sensor and the identification elements, generating a sensor signal comprising sequences of waveforms, each sequence of waveforms representing a multi-digit code identifying one of the items.
