Patent number: 10444120Abstract: A method for determining whether a defect exists in a machine. The method includes receiving a signal from a sensor that includes data related to operation of a machine. It is determined whether the data in the signal is accurate or valid and a first input is generated therefrom. It is determined whether a defect exists in the machine by analyzing the data in the signal and a second input is generated therefrom. The first input and the second input are introduced into one or more logic gates, which generate an output that indicates whether the defect exists in the machine. A user is notified when the output indicates that the defect exists in the machine.Type: GrantFiled: May 26, 2015Date of Patent: October 15, 2019Assignee: Aktiebolaget SKFInventor: Johannes Izak Boerhout
