Abstract: A computer server system comprises a communications module; a processor coupled with the communications module; and a memory coupled to the processor and storing processor-executable instructions which, when executed by the processor, configure the processor to receive, via the communications module and from a server associated with a first device, a request to perform an operation; determine that the first device cannot perform the operation; send, via the communications module and to the server associated with the first device, a signal causing the first device to output a message indicating that the first device cannot perform the operation and requesting authentication from a second device; receive, via the communications module and from the second device, a signal including authentication information; and send, via the communications module and to the second device, a signal including a selectable option to perform the operation.

Abstract: A radiation detection system may include a mobile device having a flash memory. The device may monitor various characteristics of the flash memory to determine when damage to the flash memory has occurred from radiation exposure. The device may associate damage to the flash memory with a radiation dose, and determine a level of radiation to which the memory, and thus the device, has been exposed. The device also may determine a length of time and locations where the radiation exposure has occurred. If the device determines that the level of radiation exposure exceeds a threshold associated with a safe level of radiation exposure for a human user, the device may generate an alert to the user.

Abstract: The invention is an energy-curable composition which contains a dual functional component which has at least one ethylenically unsaturated group and at least one carboxylic acid-functional group and a nanoparticle metal oxide component. The curable composition can optionally contain initiators (photoinitiators and/or free radical initiators), components which can react with the dual functional component and additives generally present in energy-curable compositions.

Abstract: Free radical, energy-curable coating compositions comprising: (a) at least one ethylenically-unsaturated monomer component; and (b) at least one chlorinated polyolefin, wherein the at least one chlorinated polyolefin is at least partly soluble in the at least one monomer component; are described along with processes for coating substrates therewith.
