Abstract: Capacitive sensors may be used to gather information, such as the presence of objects at an inventory location, such as a shelf. Two or more adjacent capacitive sensors operating at the same time may interfere with one another. Described are techniques to prevent this interference by using seed values to initialize pseudo random sequencing of an order in which capacitive sensors are in operation. The capacitive sensor, or a portion thereof, may be also be used as an antenna. Selection of an initial tuning network for use by the antenna may be determined based on output from the capacitive sensor.

Abstract: Sensors at an inventory location can be used to detect the occurrence of an event at the inventory location. For example, capacitive sensors can gather capacitance values, which can then be analyzed for changes that indicate an event has occurred at the inventory location. When an event has been detected, event data is generated and used as a possible trigger to collect additional sensor data. As an example, if an event involving items at an inventory location is detected, such an action can trigger the collection and analysis of additional sensor data, such as weight sensor data, to determine a quantity of the items added or removed from the inventory location.
