  • 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.

    Abstract: Radon detection or sensing is provided within a building automation system for a site (e.g., building or campus). As such, one or more short-term and/or long-term radon levels may be detected or monitored. The radon levels are monitored from a remote location. The building automation system may be programmed to automatically respond to a specific (e.g., unsafe) radon level and/or a change in one or more radon levels, or combinations thereof, in order to mitigate or reduce the monitored or detected radon levels. Trending, pattern comparison between radon level and other measured information, automated response, interaction or response between different radon sensors, or combinations thereof may be provided by integrating one or more radon sensors into a building automation system.

  • Patent number: 8576087
    Abstract: A radiation imaging system includes a radiation imaging cassette and a console device. A communication mode between the cassette and the console device is switchable between a wired mode and a wireless mode. Due to shortage of a battery of the cassette, the communication mode is switched to the wired mode to start charging the battery and send image data from the cassette to the console device through a cable. The console device has first and second judging sections. The first judging section judges whether or not a charge level of the battery exceeds a predetermined threshold value. The second judging section judges whether or not radiography is in progress. If it is judged that the charge level of the battery exceeds the predetermined threshold value and the radiography is not in progress, a window that indicates permission for switching to the wireless mode is displayed on a monitor.

  • Publication number: 20130285819
    Abstract: The present invention provides an inspection method of a backlight module and an inspection apparatus. The inspection method of the backlight module comprising: obtaining space brightness values of multiple positions of the backlight module on an inspection machine when the backlight module is setting in standard luminance mode, and setting the space brightness values as standard brightness values; obtaining real-time space brightness values of the multiple positions of the backlight module; comparing the real-time space brightness values with the standard space brightness values in order to determine if the backlight module is abnormal. The present invention compares the real-time space brightness values measured by the brightness meters with the standard space brightness values corresponding to the standard luminance mode of the backlight module in order to determine if the backlight module is abnormal instantaneously, and using the brightness meters to replace the luminance meters results in cost saving.

  • Publication number: 20130278427
    Abstract: A method of reporting local environmental conditions in real time is implemented by providing a sensor that takes measurements of an environmental condition; attaching the sensor to a vehicle, a person, an object such as a street lamp or other structure; and displaying visible light to the public at a scale visible from at least 30 feet from the visible light. The visible light is controlled by a microcontroller receiving information from the sensor. The visible light is either variable to depict the measurements, such as in color, frequency of illumination, or is variable in a plurality of lamps lighted in accordance with the magnitude of the measurements or in accordance with a composite index. The sensor is preferably modular so that it can be swapped in and out of a printed circuit board.

  • Patent number: 8552866
    Abstract: The invention provides an RFID tag with means for determining when such tag has been tampered and means for securing the tag to an object. The tag may use an optical or infrared transmitter/receiver pair for detecting active tag removal from the object to which it is attached; and a method of attaching the tag holder to rounded objects regardless of object diameter while still preserving tamper capability of the active tag. Alternatively the tag may use an infrared radiation sensor to determine a change infrared radiation that occurs when the tag is removed from a person, and a light sensor to determine when tag has been tampered.

  • Patent number: 8519335
    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.

  • Publication number: 20130207808
    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.
