A transfer device transfers an image formed on each of image-carrier rotating members onto a transfer belt by applying a bias voltage to the image-carrier rotating members. These conversations often occur over generalized communications channels, such as email or social network messages, which may be unstructured and ephemeral. The keyless entry device may include a haptic actuator and one or more processors that may establish a communication channel with a vehicle, communicate, via the communication channel, a command to the vehicle, receive a response to the command from the vehicle, and cause the haptic actuator to output a first haptic effect based on the response. The use of multiple energy sources provides isolation of acoustic energy and allows measurement of local resonance of the drumhead. According to one aspect of the present invention, a method for transmitting control information for additional broadcast information in a wireless communication system comprises a step in which a base station transmits control information containing information on the transmission time of the additional broadcast message, and transmits the additional broadcast message at said transmission time.
