This invention relates to a device for determining vibration characteristics of vibrated, supported, generally round, substantially ellipsoid articles, such as eggs, comprising:. The method also includes capturing authentication data from a user with a communications device in accordance with the authentication data requirement, and capturing biometric data of the at least one new verification phrase from the user with the communications device. Each occupancy sensor transmits an occupied control signal to the load control device in response to detecting an occupancy condition in the space and a vacant control signal to the load control device in response to detecting a vacancy condition. The spacer and the device may be configured to be assembled together with a trocar and an obturator.
