  • Patent number: 8890697
    Abstract: Mobile devices may minimize the radiation exposure to users by controlling the distance between the user, specifically the groin area, and the mobile device to a minimum distance. The reduction in exposure is realized due to the operation of the Inverse Square Rule on electromagnetic signal from the mobile device recognizing there is a steep fall off of signal strength resultant from increased distance between the head of the user and the source of the signal. Embodiments alert the user to a mobile device in the users pocket is in a transmission mode and thus should be removed from the users pocket to maintain operational distance between the user and the device to reduce signal absorption of the users reproductive organs. Enabled mobile devices detect the transmission mode and the acceleration of the device in determining whether to alert the user. Embodiments influence the user to maintain a minimum distance via alerts, interruptions and warnings.

  • Patent number: 8822895
    Abstract: A fiber fuse detecting apparatus provides early detection of a fiber fuse generation in an optical fiber that propagates laser light, preventing the damage from expanding. It comprises light input means arranged on a laser light incidence side of the optical fiber that inputs at least a portion of reverse direction propagation light propagating in a reverse direction to light incidenting the optical fiber, light receiving means that photo-electrically converts light input by the light input means, electric filter means that extracts from an output signal of the light receiving means a prescribed frequency band component that contains a periodic signal due to fiber fuse, detecting means that detects change of or a prescribed value in output level of the electric filter means, and warning means that emits a warning signal in response to a detection output of the detecting means. The laser light to the optical fiber is stopped or reduced by means of the warning means.

    Abstract: An assembly (13) for monitoring ionising radiation comprises a detector substrate (2) for generating electronic charge responsive to incident ionising radiation, the detector substrate (2) having an array of ionising radiation sense volumes (12) formed in it. A circuit substrate (14) supporting an array of read-out circuits (16) corresponding to the array of sense volumes is mechanically and electrically coupled to the detector substrate (14). Each of the read-out circuits (16) is switchable between first and second charge integration modes for receiving charge from a corresponding sense volume. A charge integration circuit (30) is configured in the first charge integration mode to integrate charge corresponding to sensing of a single ionising radiation detection event in a corresponding sense volume and in the second charge integrating mode to integrate charge corresponding to sensing a plurality of ionising radiation detection events in the corresponding sense volume.

  • Patent number: 8642960
    Abstract: A flux detection apparatus can include a radioactive sample having a decay rate capable of changing in response to interaction with a first particle or a field, and a detector associated with the radioactive sample. The detector is responsive to a second particle or radiation formed by decay of the radioactive sample. The rate of decay of the radioactive sample can be correlated to flux of the first particle or the field. Detection of the first particle or the field can provide an early warning for an impending solar event.

  • Patent number: 8629761
    Abstract: In a method and a system for initiating communication with an implantable medical device to conduct a wireless communication session between the implantable medical device and an external programmer device. A directional antenna is employed for initiating communication between a programmer device and an implantable medical device (IMD). The IMD is targeted by the programmer device by having an operator of the programmer device orient the directional antenna toward the IMD and transmitting a communication-initiating signal from the programmer to the IMD via the directional antenna. The directional antenna has a directional characteristic and communication range. the IMD responds to the communication-initiating signal by sending identification information to the programmer. the programmer may then use this identification to establish a communication session with the IMD targeted by the directional antenna.
