20090019933 | COMBINED ACCELEROMETER AND GYROSCOPE SYSTEM - An embodiment of the present invention relates to a combined accelerometer and gyroscope system. The combined accelerometer and gyroscope system includes a combined accelerometer and gyroscope for maintaining vibration of a mass body at a constant amplitude using an applied drive voltage, and detecting vibration signals in directions of an acceleration axis and an angular velocity axis. An acceleration axis vibration signal obtainment unit obtains the vibration signal in the direction of the acceleration axis. An amplitude maintenance control unit outputs an acceleration axis vibration maintenance control signal using the vibration signal. An acceleration axis driving input unit receives a voltage signal from the amplitude maintenance control unit and applies the voltage signal to the combined accelerometer and gyroscope. An angular velocity axis vibration signal obtainment unit obtains the vibration signal in the direction of the angular velocity axis. A force balance control unit outputs an angular velocity axis vibration maintenance control signal using the vibration signal received from the angular velocity axis vibration signal obtainment unit. An angular velocity axis driving input unit receives a voltage signal received from the force balance control unit and applies the voltage signal to the combined accelerometer and gyroscope. | 01-22-2009 |
20090264104 | MULTIMEDIA MESSAGE SERVICE METHOD AND SYSTEM - Disclosed is a multimedia message service method and system for sharing and searching for multimedia messages stored in an MM box. The MMS client has the possibility to associate an access mode (“public”, “restricted”, or “private”) to any multimedia message stored in or uploaded to an MM box. When a multimedia message is permitted to be shared, the MMS clients who have been granted access to the multimedia message can be notified of the shared multimedia message. When the MMS client requests to view or retrieve a multimedia message, the MMS relay/server checks if the MMS client has been granted permission to access to the multimedia message. If the MMS client has been granted permission to access to the multimedia message, the MMS relay/server allows the MMS client to access the multimedia message. | 10-22-2009 |
20100056077 | METHOD AND SYSTEM FOR INTERRUPTED FLOOR RECOVERY IN PUSH-TO-TALK OVER CELLULAR NETWORK - As described above, when a particular PoC client participating in a PoC session requests media transmission to a PoC server during transmission of media from another PoC client, the PoC server transitions the PoC client with the floor to a suspended state by sending an MB Suspend message and grants the floor to the requesting PoC client. After media transmission of the interrupting PoC client, the PoC server returns the floor to the interrupted PoC client. Therefore, the privileged PoC client in a current PoC infrastructure interrupts the ongoing conversation and sends media, after which the floor is returned to the interrupted PoC client without issuing an explicit media request from the interrupted PoC client. Even in the pre-emptive case scenario where the pre-emptive PoC client interrupts the ongoing conversation, the conversation can be continued in a natural way. | 03-04-2010 |
