Contact sensing device and system

摘要

A contact sensing device and system includes all the required sensing components, including a capacitive sensor and an elongate portion configured to generate at least one sense signal upon contacting at least one substance. All necessary sensing components are contained in a handheld device and do not require conductive contact surfaces to detect contact with a target area. The sport of fencing benefits in particular from this contact sensing device and system.

主权项

1. A handheld device for sensing contact with a substance comprising:
a capacitive sensor comprising an elongate portion comprising a blade of a fencing weapon configured to generate at least one sense signal upon said elongate portion contacting at least one substance; a processor for receiving said at least one sense signal from said capacitive sensor, processing said at least one sense signal to determine a property of the at least one substance, and for generating an indicator signal; and an indicator which receives said indicator signal and indicates if the capacitive sensor contacts the substance; wherein at least a portion of the elongate portion of said capacitive sensor further comprises a contact sensing lead for sensing contact between a lateral side of said at least a portion of the elongate portion and said at least one substance.
