Abstract: A gateway device for controlling sensor network transmission frequency comprising: means to detect the gateway device location, transmission means arranged to at least transmit a beacon signal in the UHF band, characterized in that the gateway device is arranged to detect radio frequency band limitations associable with the detected location, and further sending beacon signal on 868/915 MHz frequency, or on 2.4 GHz frequency or other available ISM/SRD frequency if frequency band limitations associable with the gateway location are detected. Corresponding arrangement and method are also presented.

Abstract: A gateway device for a sensor network comprising: communication means to communicate with an aircraft interface device or other communication means provided by aircraft, short-range wireless communication means for communicating with nodes via short range communication means, characterized in that the gateway device is arranged to receive flight status information from the aircraft interface device and to facilitate control of nodes in accordance with the flight status, such as that the gateway sends the nodes a command to disable all wireless transmission when the aircraft status is take off or landing, and a command to utilize only short-range wireless transmission means when the aircraft status is climb, cruise or descent. Corresponding arrangement and method are also presented.

Abstract: The present invention relates generally to acquisition of data from RFID devices (132-136), such as sensor data. Prior art systems of active RFID devices have a problem of high average power consumption, and therefore, the energy source of the RFID devices needs to be replaced or charged frequently. The present invention provides a new solution wherein the RFID device has a power saving mode in which the receiver of the RFID device has a decreased ability to receive/detect RF signals. The RFID device may include a timer which is functional during the power saving mode, and the receiver of the RFID device will turn into active mode at a point of time based on the time value of the timer. Signal strength of an RF channel is indicated with a receiver, and transmission of data is dependent on the indication of the signal strength.

Abstract: Anchoring devices, anchoring systems for intervertebral implants, intervertebral implants, and instruments and methods for implanting implants are disclosed. In preferred configurations, these various objects share the feature of comprising or cooperating with an anchoring device (1) having a body comprising at least one curved plate (10) elongated along a longitudinal axis (L), designed to be inserted through a passage (21) crossing at least a part of implant (2), in order to penetrate into at least one vertebral endplate and attach implant (2) onto this vertebral endplate by means of at least one stop retaining the implant, characterized in that the body comprises at least one longitudinal rib (11) on at least a part of at least one of its faces, said rib (11) being designed to cooperate with a groove (211) made in passage (21) of implant (2).
