Patent number: 8497465Abstract: Helmet-mounted switch systems are disclosed. A helmet-mounted switch system comprises a mount portion, an electronic device, a power source, at least one accelerometer, and a processor. The mount portion is rotatable around a rotation axis. The electronic device is mounted to the mount portion. The power source is configured to switchably supply power to the electronic device. The at least one accelerometer is operable to measure an acceleration of the mount portion. The system may also include at least one gyroscope operable to measure a rotation of the mount portion. The processor is configured to receive acceleration data. The processor is programmed to determine whether the mount portion is rotating around the rotation axis based on the acceleration data. The processor is programmed to change a power state of the electronic device when the mount portion is rotating around the rotation axis.Type: GrantFiled: May 28, 2010Date of Patent: July 30, 2013Assignee: Exelis, Inc.Inventor: John Barnett Hammond
