Method, system and computer readable medium for providing an output signal having a theme to a device in a short distance wireless network

A method, system, and computer readable medium allows a user to select an output signal for device/terminal in short distance wireless network. In embodiments of the present invention, the output signal is a ring tone, alarm, background image, vibration signal, font type, or portion of a motion picture. In embodiments of the present invention, a system comprises a first and second device, in a short distance wireless network, generating a first and second output signal. A cellular device generates a first and a second short-range radio signals responsive to a cellular signal from a cellular network. The cellular signal includes a first multimedia file for the first device and a second multimedia file for the second device. In an embodiment of the present invention, the first multimedia file and second multimedia file are thematically related. In an embodiment of the present invention, a processing device is coupled to the cellular network and stores the first and second multimedia files. In an embodiment of the present invention, a user selects a theme on a device or at a web site in order to change the output signals in the short distance wireless network. In an embodiment of the present invention, the output signals are changed periodically without user intervention. In still a further embodiment of the present invention, promoters or users pay a telecommunication network provider for conveniently and safely changing the output signals.

Multi-sensor integrated synchronous control method and system for high-precision time-space data acquisition

The invention provides a multi-sensor integrated synchronous control method and a multi-sensor integrated synchronous control system for high-precision time-space data acquisition. The method comprises the following steps of: establishing a time-space reference circuit which provides time reference and space reference; establishing a linear reference coordinate system through the time reference and the space reference, and implementing conversion between the linear reference coordinate system and a geodetic coordinate system; sending an analog control signal to an active synchronous sensor according to the preset parameters to realize synchronous control of the active synchronous sensor; and receiving an external event pulse signal, and responding to the interruption generated by the external event pulse signal to realize synchronous control of a passive synchronous sensor. An active synchronous control circuit and a passive synchronous control circuit are provided; and based on the time and space references provided by the time-space reference circuit, the circuits can expand random multiple sensor synchronous control cases aiming at different sensors and control requirements, and have extremely strong expansion and flexible functions.
