Title:
INTERLOCK APPARATUS FOR FITNESS EQUIPMENT
Document Type and Number:
WIPO Patent Application WO2002049722
Kind Code:
A3
Abstract:
Interlock apparatus for fitness equipment comprises a microprocessor [105] receiving grip signal inputs from grip sensors [101A, 101B] mounted on a load-bearing component of the fitness equipment. Signal conditioners [103A, 103B] provide noise filtering, signal debouncing and digital inputs for the microprocessor. Grips status monitors [106A, 106B] provide grip status signals used by microprocessor [105] to determine the validity of the grip signals. Microprocessor [105] provides validity criteria which changes depending on the grip status inputs. The apparatus detects sensor connection changes and abnormal sensor and circuit operation and modifies logic functions to improve the capability and reliability of safety locks and brakes on the equipment.
