Abstract: A mobile device mounting system includes a device case and a mount. The device case includes: an insert including a rectangular bore and defining a set of undercut sections about the rectangular bore; and a first set of magnetic elements arranged in a first pattern about the rectangular bore. The mount includes: a body; a polygonal boss extending from the body and configured to insert into the rectangular bore; a set of locking jaws arranged on the polygonal boss configured to transiently mate with the set of undercut sections to constrain the polygonal boss within the rectangular bore; and a second set of magnetic elements arranged in a second pattern about the polygonal boss and configured to transiently couple to the first set of magnetic elements to transiently retain the mount against the device case and to drive the set of locking jaws toward the set of undercut sections.

Abstract: A radiation detection apparatus (2) is disclosed. The apparatus includes a housing (20), a window (26) at least partially transparent to electromagnetic radiation in a first wavelength range and a photomultiplier tube (24) for generating an electrical output signal dependent on the intensity of the electromagnetic radiation. A resiliently deformable optical coupling (28) is located between the window and the photomultiplier tube for allowing at least some electromagnetic radiation passing through the window to enter the photomultiplier tube, and a scintillator element 8 converts gamma radiation into visible light in the first wavelength range entering the photomultiplier tube.

Abstract: The invention comprises a radiation and contamination monitor for the monitoring of radiation and contamination. The instrument is intrinsically safe and comprises a radiation detector, a power source, a signal processor and a display, said power source, signal processor and display being housed within a sealed instrument housing formed from a non-metallic material which is resistant to static discharge. The detector may be housed in a detachable housing for contamination monitoring.

Abstract: Provided herein are methods and systems relating to location-based services such as social networking, providing demographic information, tracking mobile devices, providing business information, providing an adaptable user interface, remotely effecting a change on a portable electronic device, providing a geofence, outputting location-based information on a mobile device, varying transmissions to and from a mobile device, providing location-based alerts, verifying transactions and tailoring information to the behavior of a user.

Abstract: For a client seeking network resources from a network site, such as a web page, audio, visual, or other data, where the network site's desired network resources are also provided by mirroring network hosts, measurements are made to determine a communication efficiency between the client and the network site and mirroring network hosts. The client is then directed to communicate with the network site or a mirroring network host according to which had the highest measured communication efficiency with the client. In such fashion, real time adjustments can be made so as to more optimally distribute client network resource requests across all available sources of the desired network resources, and provide for real time load balancing and fail over of disabled hosts.
