Monitoring system
A monitoring system for determining whether an object is touched by a living body includes a receiver and a piezoelectric sensor attached to a substrate such that when the substrate is attached to the object. The piezoelectric sensor generates an output signal as a function of whether the living body is in contact with at least one of the substrate and the object. A processor processes the output signal to determine whether the living body is in contact with at least one of the substrate and the object and outputs a contact information signal containing information indicative of whether the living body is in contact with at least one of the substrate and object based on the determination. A transmitter transmits the contact information signal to the receiver.
1. A monitoring system for determining whether an object is contacted by a living body, the monitoring system comprising:
a receiver;
a piezoelectric sensor attached to a substrate such that when the substrate is attached to the object, the piezoelectric sensor generates an output signal as a function of whether the living body is in contact with at least one of the substrate and the object;
a processor that processes the output signal to determine an amount of time that the living body is in continuous contact with at least one of the substrate and the object as a function of whether a frequency of the output signal falls within a predetermined range corresponding to a biological tremor, the processor outputting a contact information signal containing information indicating the amount of time the living body is in contact with at least one of the substrate and object as a function of the determination; and
a transmitter that transmits the contact information signal to the receiver.
2. The monitoring system according to claim 1 , wherein the piezoelectric sensor also detects bending forces applied to the substrate and the output signal contains information indicative of such detected bending forces.
3. The monitoring system according to claim 2 , wherein the processor determines the amount of time that the living body is in contact with at least one of the substrate and the object as a function of whether or not the frequency of the output signal falls with the predetermined range and whether or not the output signal indicates that a predetermined level of bending forces have been applied to the substrate.
4. The monitoring system according to claim 1 , wherein the processor only outputs the contact information signal when it has determined that the object has been picked up.
5. The monitoring system according to claim 1 , wherein the processor only outputs the contact information signal when it has determined that the living body has been in contact with the substrate and/or the object for a predetermined period of time.
6. The monitoring system according to claim 1 , wherein the object is a product.
7. The monitoring system according to claim 1 , wherein the object is a display case.
8. The monitoring system according to claim 1 , wherein the receiver includes a display which displays information indicating that the living body has been in contact with at least one of the substrate and the object.
9. The monitoring system according to claim 1 , wherein the receiver includes a display which displays information concerning the object.
10. The monitoring system according to claim 9 , wherein the information is sales information relating to the object.
11. The monitoring system according to claim 1 , wherein the receiver includes a notification unit that provides an indication that the living body has been in contact with the object for at least two seconds.
12. The monitoring system according to claim 11 , wherein the indication is visual.
13. The notification system according to claim 12 , wherein the indication is also audible.
14. The notification system according to claim 1 , wherein the processor determines that the object has been picked up by the living body when the frequency of the output signal falls within the predetermined range and the length of time between two spikes in the magnitude of the output signal exceeds a first threshold, the first spike having an absolute value which is greater than a second threshold, the second spike having an absolute value which is greater than a third threshold.
15. The notification system according to claim 14 , wherein the living body is a human and the receiver displays information indicating that the human has an interest in purchasing the object.
16. The notification system according to claim 1 , wherein the piezoelectric sensor is not an acceleration sensor.
17. The notification system according to claim 1 , wherein the living body is a human and the receiver provides in indication that the human has an interest in purchasing the object as a function of the amount of time that the living body has been in contact with at least one of the substrate and the object.
