Title: Airbag jacket activating system

Applicant(s): Honda Motor Co Ltd [JP]

Publication number: CA2733752 (A1)

Publication date: September 24, 2011

Abstract: Provided is an airbag jacket activating system capable of: securing the confidentiality of the signals; and activating an airbag jacket with precision. An airbag jacket activating system includes: radiocommunications transceivers configured to make RF communications and LF communications, respectively; an acceleration sensor configured to detect acceleration of a motorcycle; an update unit configured to update an LF communications ID, to code the updated LF communications ID together with an RF communications ID, and to transmit the coded updated LF communications ID and the coded RF communications ID to an airbag jacket through RF communications; an update unit configured to store the updated LF communications ID in a case where the LF communications ID is received together with the RF communication ID; a control unit configured to cause the coded RF communications ID and an ignition signal to be transmitted through the RF communications, and to cause the LF communications ID and the ignition signal to be transmitted through the LF communications, in a case where the acceleration exceeds a predetermined value; and a control unit configured to deploy the airbag jacket in a case where the ignition signal is received together with the RF communications ID or the LF communications ID.

Title: Wireless sensor network system for underground mines and application thereof

Applicant(s): Yong Ma

Publication number: CN102137511 (A)

Publication date: July 27, 2011

Abstract: The invention relates to a wireless sensor network system for underground mines and an application thereof. The wireless sensor network system comprises a ground monitoring system arranged in a control room, wireless communication base stations widely distributed in mine roadways, radio tags adhered to personnel or equipment, an environment monitoring sensor and personnel wireless communication equipment. A wireless sensor network organically integrates a mine personnel positioning system, the environment monitoring system and mine personnel communication systems into one system. The wireless communication base station of the wireless network is powered by a battery, thus periodically sleeping so as to reduce the power consumption; and the base stations are communicated through radio frequency identification. The network has a self-restoration function, and the network base station can start up a routing reestablishing mechanism when the partial network has a crash. The network has a data collection function, and can be used for performing cross-layer analysis on the received frames in the base stations and repacking the frames, thus acquiring higher network communication efficiency.

Title: Intelligent bus stop display panel

Applicant(s): Univ Shanghai

Publication number: CN102129782 (A)

Publication date: July 20, 2011

Abstract: The invention discloses an intelligent bus stop display panel, which is characterized in that the general packer radio service (GPRS) communication module and the Bluetooth short-distance communication module of the bus station are connected to a micro controller through serial ports; an light emitted diode (LED) display screen and a temperature and sound sensor module are connected to the micro controller through input output interfaces; a solar cell panel and a storage battery combined module are connected to the micro controller as well as each module circuit; the Bluetooth module is used for searching for the stop information of bus; the communication between the bus station and the bus station is realized by using the GPRS communication module; the position information of the bus is transferred in real time; the real-time position of the bus in each route is displayed by the LED display screen, thereby informing the passenger waiting at the bus stop display panel of the stop time of the bus; and for the passengers not at the bus stop display panel, the information can be sent to the bus stop display panel in the manner of sending short massage and then the stop time and the real-time position information of each bus under the bus stop display panel are automatically replied through the GPRS, thereby being convenient for distant passengers to make a schedule as early as possible.

Title: Wireless communication via seabed for underwater seismic detection network

Applicant(s): Wireless Fibre Systems Ltd [GB]; Hyland Brendan [GB]; Rhodes Mark [GB]

Publication number: GB2472428 (A)

Publication date: February 9, 2011

Abstract: An undersea seismic monitoring network comprises at least one underwater vehicle and at least two monitoring stations located on the seabed. Each of the monitoring stations has at least onesensor for gathering seismic data and a radio modem for data transfer with the underwater vehicle via a first wireless connection formed by electromagnetic radiation through the water. A second wireless connection is established between the monitoring stations, formed by the propagation of an electromagnetic signal at least partially through the seabed. The first wireless connection may support a higher data transfer rate than the second connection. The modem may only be activated when the vehicle comes within a predefined range of the station. The stations may each further comprise a storage device to store the gathered data and transmit it via the first connection to the vehicle, and rechargeable power sources which may be recharged via magnetic coupling with the vehicle.

Title: 4D (Four Dimensional) thunder collecting method of sensor network

Applicant(s):Univ Beihang

Publication number: CN101975894 (A)

Publication date: February 16, 2011

Abstract: The invention belongs to the field of natural situation data acquisition and analog, specifically a 4D thunder collecting method using a sensor network. The method comprises the following steps of:

1. 1.

   designing multiple physical attributes sampling nodes of the thunder, and collecting physical parameter information such as radio frequency spectrums, thunder clap and the like of space 3D lightning shapes and thunder by using the sensor network in a large range, wherein each network node comprises the following devices: a low-speed camera, a high-speed camera, a sound detector, a global positioning system, a 3G wireless communication device, and a radio wide frequency spectrum analyzer;

2. 2.

   carrying out multilevel sampling in thunder areas by combining fixed-point collection and mobile collection;

3. 3.

   carrying out the synchronization of data acquisition by the calibration of multi-node multi-device;

4. 4.

   transmitting multi-node large-scale sampling data by the 3G wireless communication device; and

5. 5.

   generating a 4D thunder sampling database.

The invention has the characteristics that the 3D shapes of lightning, thunder clap and radio frequency spectrum can be synchronously acquired and the collection on large-scale thunder data is realized by the combination of the fixed-point collection and the mobile collection. In the invention, the collected thunder data can be applied to the meteorological environmental monitor and the thunder simulation based on physic.
