Patent number: 8416972Abstract: A hermetically sealed actuator design for absorbing and reducing the effect of sound or vibration energy from a vibrating surface. The device comprises a body (1) containing a magnetostrictive core (2-6) a reaction mass (7) for energizing the actuator by compression, and a bearing or lever system to control the movement of the reaction mass. The actuator has a foot (11) for receiving the vibration from the structure into the device and a sensor (13) for monitoring vibration levels. The device can also function as an audio transmitter whereby it vibrates the surface onto which it is mounted and can be used for audio trans-10 mission through the structure or noise and vibration reduction by driving the surface out of phase with the vibration received from the structure.Type: GrantFiled: October 3, 2008Date of Patent: April 9, 2013Assignee: FeONIC PLCInventors: Martin Geoffrey Aston, Kamlesh Prajapati, Neil Munns, Christopher Tiler

Publication number: 20080034592Abstract: A razor has a thin shaving blade (21) arranged so as to make direct contact with the user's skin, in use, and driver means (24, 25) for vibrating the blade as it is moved in contact with the user's skin. In a preferred embodiment the razor has a thin shaving blade (21) provided with a layer (22) of giant magnetostrictive material on at least a surface thereof and means (24, 25) for applying an oscillating magnetic field to the blade such that the surface of the blade is caused to flutter.Type: ApplicationFiled: July 29, 2005Publication date: February 14, 2008Applicant: FEONIC PLCInventors: Brian Smith, Kamlesh Prajapati
